We could not be happier with Sterling Ridge Contracting! We did an addition and whole house renovation. Spencer, Walter and the team were extremely reliable, detailed and a pure pleasure to work with. We have heard so many horror stories from family and friends about construction experiences, so we were very hesitant. From our first meeting with Spencer, we knew we had a quality company. The bid process was so incredibly thorough that there were no surprises during the construction. Even in the midst of the Covid-19 pandemic, Spencer knew exactly what needed to be done to keep the project on schedule without sacrificing quality. Sterling Ridge managed to even finish 3 weeks early! We’re in love with the final product, and couldn’t recommend them enough!

Sterling Ridge Contracting, an incredible business started by the talented and capable hands of one generation and now, into the equally talented and capable hands of the next. I have done business with both. My husband and I had Sterling Ridge build our dream house in 2013. The workmanship was impeccable. The caring of the men behind the company was unparalleled. They will move heaven and earth so you will have an incredible experience and the finished product is always superb. Sadly, my husband passed away and I decided to sell the house and purchase a house with my son and daughter-in-law.
My high praise, I believe is proven by the fact that when we were in need of an extensive remodel on the newly purchased house, Sterling Ridge was the only company we would consider. Spence stepped up, and with patience, knowledge, efficiency and professional expertise got the job done. From the very first step, we were taken through to the incredible result. I have seen this company literally and figuratively move mountains to get the result we envisioned. We couldn’t be happier with Sterling Ridge.

The best decision we ever made was to use Sterling Ridge Contracting for our addition. After meeting with a few contractors before Spencer, we knew right away that he was who would become our guy. Reliable, professional and responsible from day one. Personable, friendly and accommodating from day 2, when he met our kids. He even drove our girls to school one morning when I was stuck in the driveway!
Spencer and Rick were extremely knowledgeable and showed great expertise from beginning to end. Their attention to detail is unmatched. They offered helpful advice all while partnering with us to make decisions regarding our newly built master bedroom.
From start to finish, they kept us up to date with with tentative timelines. Spencer and Rick were organized and meticulous, on time for every meeting and let nothing fall through the cracks. We were so impressed with the temporary insulated wall they built, equipped with a door and digital lock, so as not to disturb us, or freeze us out. Sterling Ridge was the only group who thought that idea up.
Spencer and Rick hire only the best, most reliable subcontractors, of whom we got to know and trust. They respect your home, as well as provide professional services and produce immaculate work.
They were involved every step of the way and we couldn’t be happier with the end result. We HIGHLY recommend Sterling Ridge Contracting for any and all construction projects. They do not disappoint!!!!

Sterling Ridge Contracting came highly recommended to us by friends who had used them for a number of large projects at their home.  I knew from seeing their home that it would be a great decision.  But honestly, they surpassed all my expectations.
Our project included a complete kitchen renovation which involved removing a bearing wall as well as an addition of a wrap around porch.  Our home was originally built in 1900 and with that came some unexpected structural challenges that Sterling Ridge and their team were able to solve with creative, high quality, yet cost efficient solutions.   During the entire process we were always kept in the loop as to what was happening and what was going to happen next.   I was extremely impressed with their scheduling and coordination of sub-contractors.  When one sub finished, literally the next day, the next sub was on the job.  A day never went by without work being completed.  We had hoped to be ready for Christmas, but we were ready for Thanksgiving!   I look forward to using them again for additional projects we have planned.

Prior to our renovation, we recently moved across the country and purchased an outdated home in Mahwah. Because of our lack of knowledge about the area, we were unsure of anyone to entrust in this project. From our first interaction with Spencer, we knew we were working with a reliable contractor. Our house project consisted of gutting the existing house, reworking the exterior, plus a large addition. Spencer and his professional team of subcontractors were honest, hardworking, and dedicated to fitting within our timeline and budget. It's rare to find a contractor who is as organized as the team at Sterling Ridge. Consistent work was happening each weekday of our renovation. Any issues or changes were communicated well in advance. Our large project finished on-time and at budget. We are so pleased with how our home turned out and haven't hesitated to recommend Sterling Ridge on many occasions.

When I think about Sterling Ridge Contracting two words come to mind: Professionalism and Dedication. From the start of the scope of work to the proposal, every detail was discussed so that there was no ambiguity. This attention to detail was evident throughout the project. Sterling Ridge renovated our kitchen, built a new laundry room and installed a new deck. The team that worked on our project was dedicated and never missed a day. Many times you hear about contractors jumping from project to project. Our team usually worked 6 days a week.  I guess the ultimate reference is... we would definitely contract with Sterling Ridge again!

Working with Sterling Ridge on our renovation was an excellent experience from start to finish. When we set out to find a contractor, we received at least five independent recommendations for Sterling Ridge. Each recommendation emphasized their professionalism and superior workmanship. We were not disappointed. The process, costs and variables were outlined for us from the beginning in a clear and transparent manner. Spencer was terrific at keeping frequent communication with us regarding the status of the job, any issues that arose, and proposed solutions to those issues. And despite certain vendor issues threatening the targeted completion date, Spencer was able to shift the work plan around so that we were able to move into the house right on our target date. The pictures of the finished product speak for themselves – we are thrilled with how everything turned out. Sterling Ridge made our vision a reality and were a true pleasure to work with.

We hired Sterling Ridge to build us our dream home and knew right away that we absolutely made the right choice! Rick was beyond professional and knowledgeable. His organization, experience and accessibility was paramount in creating a stress free experience for my husband and I. Even after the house was complete we found that we could still count on Rick for quick response and guidance. Anyone who has the opportunity to work with Sterling Ridge should consider themselves very fortunate as I couldn’t imagine there is anyone better out there!

Sterling Ridge delivered superior service throughout our entire garage project. You have to have confidence in a contractor to go away for two weeks and not have a thing to worry about. The craftsmanship and quality is first rate. Options were always offered throughout the building process, and Rick was in constant communication. The project came in on time and on budget, and we have gotten so many compliments on our new garage. We are just thrilled with Sterling Ridge and hope we will be able to use them again!

Spencer and his team did our basement renovation. Sterling Ridge far exceeded our expectations on the entire job. The planning process was seamless, the actual work was efficient and on time, and the end result is gorgeous! Spencer is knowledgeable and available, and his team was trustworthy and truly talented. Spencer felt like a true partner during the process, helping guide in decision making with the utmost patience! The word "renovation" is usually accompanied by words like "delays," "headache," "unforeseen costs." Sterling Ridge is a class act, and we did not experience any of the usual issues of a stereotypical renovation. We are looking forward to doing future projects on our home with Spencer and Sterling Ridge.

Gary and Felicia

The words that come to mind for Sterling Ridge Construction are: Professional, Organized, Punctual, Great Communication, Detail Oriented and, most importantly, Great Craftsmanship! When selecting a contractor for our project, it was a very easy decision for us to choose them based on how thoroughly they reviewed the architectural drawings and the existing house structure during the bidding period. They provided an estimate detailing accurate construction costs and timeline for completion. The construction team arrived on time daily executing to the plan. Rick was in constant communication with us multiple times a week. As with all construction projects, things had to be adjusted, and we partnered to make the decisions that worked for us, while maintaining construction standards. When the project came to an end, we were sad to see Rick and team go as we were used to speaking with them weekly for months! Every chance we get, we recommend them to friends and relatives as they are the best construction team we have worked with!

We engaged Spencer on a full gut renovation project in Ridgewood, and have continued to engage him on additional projects since then.
We give Spencer and his team our 5-star endorsement across all categories.
Working with Spencer is a breath of fresh air. He is incredibly knowledgeable and professional and perhaps most importantly Spencer is reliable, trustworthy, and honest - and he only works with subcontractors that embody these same principles.  When we embarked on such a large project we were bracing ourselves for a lot of stress and anxiety and everyone we knew told us to expect to come in over budget and for the project to finish late. “That’s just how it works”, we were told.
Our experience with Spencer and Sterling Ridge was the opposite. The entire process, end to end, was fun and exciting.  Spencer worked with us like a true partner. He shared our excitement and with his meticulous management of the details of our project, timeline, and allowances budget, we were able to maintain the energy and enthusiasm throughout the entire process.
We never had one delay (in fact, he worked hard to sprint to the finish line in order to get us in AHEAD of schedule so we could host Thanksgiving for our family in our new home), and we came in right on budget. Of particular note is the quality of Spencer’s communication. He was incredibly responsive on any/all mediums (email, phone, text) and punctual for our in person meetings.  He did a fantastic job of describing various pieces of the job and decisions in a way that easy for us to understand. Most people finish large projects and are happy that it becomes part of their past, but we look back on the time fondly with great memories.  We couldn’t be happier with the end result.

We have been using Sterling Ridge ever since they built our dream home in 2008. The building process was the perfect collaboration between our ideas and their expertise. Rick and Spencer are a class act...they are extremely knowledgeable, responsive and all around great people to work with. Their work is of the utmost quality and they always stand behind their work. The ultimate testament of the faith we have in their work is that we continued to use them for all other building projects thereafter...a detached garage, a pool house and a pool pavilion. We wouldn't think of using any one else!

Over the years, I have worked with Spence and Rick on countless projects at my office park. They have always exceeded expectations for myself and my tenants. Every project is delivered ahead of schedule, on budget, and ready for the tenant to occupy their new space. I look forward to working together for years to come.

We incurred storm damage from Hurricane Sandy. From dealing with the insurance company to getting our home back in order, Spencer's expertise was invaluable. His organization, knowledge and attention to detail made the whole process so easy to live through. Thanks Spencer!

While renovating a home can be quite overwhelming, Sterling Ridge Contracting made the experience very palatable. I met with the Purveyors and Subcontractors prior to the renovation and they were all knowledgeable and proficient. In addition, the Subcontractors were considerate and respectful and the remodeling process was completed in a timely manner with minimal disruption.

Building a home is probably one of the most stressful things one can do. My wife and I struggled for months with who would build our dream house in the country. We compared the numbers, the references and simply who made us feel most comfortable. We did not choose the lowest bid as we are well aware that you really do get what you pay for. In this case we could not have been more right about our decision to choose Sterling Ridge Contracting. We had almost no stress, the building process was smooth, orderly and actually a pleasure. The house is exactly what my wife and I envisioned and it was finished a week early.

My wife and I would like to express our sincere appreciation to Spencer, Rick, and the entire team at Sterling Ridge Contracting for their outstanding work with the addition to my house. Spencer’s impeccable attention to detail and quick responses to our questions were unmatched by any other contractor we have worked with. The entire team at Sterling Ridge was meticulous in keeping the job site clean every day and showed great respect for our living space. The finished product far exceeded our expectations and we could not have made a better choice than hiring Sterling Ridge for our addition. I submit my highest recommendation to Spencer and Sterling Ridge Contracting for anyone looking for the best work possible.

My wife and I could not be happier with Spencer and his team and would unreservedly use him again for our next project. The quality of the work was top-notch, but it is the "extras" that set him apart from contractors we have used in the past. First and foremost, Spencer is a real gentleman and deals with people with honesty and integrity. He truly makes every effort to do what is right, not just what is quickest or cheapest for him. There were so many examples of this, but one in particular stands out. We ran into unforeseeable structural issues, and Spencer fixed everything to beyond the required code on his own dime, sticking to his original quote. Spencer is incredibly organized and stays on top of every aspect of the project. I never had to remind him of anything or chase him and nothing slipped through the cracks. His pricing was very fair, especially given the quality of the work, and he didn't price gouge for any extras that came up on the job. His team was very meticulous, always showed up on time, worked extra to stay on schedule, and always cleaned up at the end of the day (Spencer even sent cleaning crews periodically!) We had a baby in the middle of our construction, and the sensitivity and conscientiousness of Spencer and his team was outstanding. Couldn't recommend Spencer more highly.


Mahwah, NJ

Thanks to Sterling Ridge and their team, my dream kitchen came to fruition. All my fears and trepidations dissolved the moment Spencer and his men walked through the door. Their meticulous demolition and detail-oriented work, which involved the installation of cabinetry, moldings, appliances, and hardwood floors, left me wondering why I had not undertaken this renovation sooner. Spencer is a class act contractor, whose first priority is customer satisfaction. Looking forward to my next Sterling Ridge project!

Our bathroom remodeling project was quite the task for our 126 year old home, but Sterling Ridge did a phenomenal job! Our new bathroom is absolute perfection; cozy and inviting with workmanship you’d see in a magazine. Everything happened according to plan, right on schedule, and there were absolutely NO issues with any of the inspections! The crew was extremely clean, polite and respectful of our home, being very careful not to damage anything, and they cleaned up at the end of each work day. Spencer was involved in every aspect of the project and kept us informed from beginning to end We couldn’t be happier and highly recommend Sterling Ridge for your next home remodeling project!

After buying a home that had not been updated since it was initially built about 40 years ago my wife & I knew we were in for a bit of a project. The stress of trying to find the right contractor along with comparing estimates/bids can be overwhelming even before you dive into the renovation process itself. Looking back we couldn't be happier that we hired Spencer and his team from Sterling Ridge Contracting as they made the process as easy & stress free as possible from the start. Even with a very tight deadline the quality of work was top notch and Spencer is as meticulous, responsive, and honest as they come (all things you worry about when hiring a contractor). There is no doubt that throughout the process he cared about doing what was right not what was cheapest or easiest for him. We would not hesitate to hire Spencer and his team again for the next series of projects we have as they completely beat our expectations while dealing with them through our most recent renovation.

A friend suggested that we contact Rick for a garage project we were thinking about. Frankly, we built our home 10+ years ago but decided to wait on building a garage. We always knew we wanted a garage, but it was not until we met with Rick that we felt comfortable moving forward. Meeting with Rick was a great experience. We felt that he understood our priorities and he did a great job of helping us to see how our dream could be realized. Every step along the way he kept us informed of progress and what to expect. When there were questions about options he took the time to meet with us and fully discuss. He shares ideas and options that make it easy to decide how to move forward. Our garage is now completed and we could not be happier. On time, on budget and even better than we originally planned. Does not get any better than that!

Jeff and Emily

Where do we start! Working with Spencer and his team was an absolute joy. His professionalism, organization and communication made our renovation project easier than we could have ever expected. From our first meeting to our final walk though, Spencer was always timely, fair and honest. Whenever we visited the house during the project it was clean, well organized and the work itself was extremely well done. We couldn't be happier with the finished project and although we plan on enjoying our newly renovated house for years to come, we would work with Sterling Ridge Contracting again in a heart beat!

Working with Spencer Cosgriff and Sterling Ridge Contracting on our home was an absolute pleasure from start to finish. We purchased a 1905 farmhouse and we wanted to modernize it to work for a family while still keeping much of the original charm and character that drew us to the home in the first place. It was an enormous undertaking, and Spencer actually managed to made it fun—all while keeping our project on time, on budget, and delivering us the home of our dreams. We would hire him again in a heartbeat. Here's why.

First of all, Spencer treated our home like it was his own. His attention to detail was remarkable, and he ensured that everything was done the right way. If something wasn't done properly the first time, it was corrected at no expense to us. Also, Spencer works with the best trades in the business. We loved meeting all the people who worked on our project. Without exception, they were extremely talented, knowledgeable, professional people who took great pride in their work. We can see their hard work and craftsmanship in every detail of our home today.

Finally, Spencer was incredibly responsive and communicative throughout our project. He was always reachable--via phone, text, email or in person. No matter how many questions, thoughts or ideas we had, we were never passed off to someone else in the company. It is hard to find a good contractor, but Spencer is trustworthy, honest and up-front, creative, extremely organized and very knowledgeable. Plus, our dog and our baby boy loved him. We cannot speak highly enough of him or of our experience with Sterling Ridge Contracting.

We recently worked with Spencer on our basement renovation. He was a pleasure to work with from beginning to end. He took away all of our anxiety by starting us out with a detailed timeline and to-do lists.

Spencer is so easy to work with, highly professional, reliable and an absolute perfectionist. If he saw anything that was not to his standards throughout the project, he would let us know and fix the problem immediately.

The team that Sterling Ridge works with is nothing short of the best in the business. The quality workmanship speaks for itself. Everyone stuck to Spencer's standards, and schedule, and were wonderful to work with.

The lines of communication were always open. It was very easy to reach Spencer by phone, text message or email at any point. We saw him almost every other day as he continually monitored the progress of the basement.

We wholeheartedly recommend Spencer and Sterling Ridge to anyone. Our finished basement and the entire renovation process exceeded our expectations. We also must mention that the project wrapped up one day before the deadline Spencer had set!

We were working on a huge hardscaping/landscaping project on our home and our landscape contractor discovered that we needed structural repairs to the exterior before they could continue. He introduced us to Sterling Ridge Contracting. Spencer evaluated the work and provided us with an estimate as well as a timeline. Given several circumstances, they were able to complete the work earlier than expected. I appreciated that they were able to complete the work sooner but more appreciative that he did not over promise and under deliver.

Since we were so impressed with Spencer and his team, we asked him to provide us with an estimate for the face lift of the exterior, another huge project we were about to undertake. We received several proposals and felt Sterling Ridge was a great fit. As they were working on the outside, we had two issues major issues occur inside (one after the other) that required a gut renovation of two rooms. Thankfully Spencer was here to address each. One happened at a time when we were traveling out of the country and Spencer handled everything on our behalf. He goes above and beyond.

As with any home, we will have ongoing projects and look forward to working with Sterling Ridge and their team again. Both Spencer and his team are courteous and professional. I met with Spencer almost daily during our projects. He would provide an update on what was happening and when. There was never a “surprise." He doesn’t let anything slip through the cracks. It’s been an amazing experience to have a contractor that communicates and works efficiently and effectively! He and his team were pleasure to work with!

We've dealt with several contractors for various projects since moving to Mahwah 3 years ago and for the most part had been disappointed. Delays, cost overruns, poor workmanship and lack of professionalism were common occurrences. When we decided to finish our basement it was of utmost importance that we get it right. A friend had recommended Sterling Ridge and Spencer in particular. From the moment we met him we knew that Sterling Ridge would be the perfect partner for our project.

Spencer provided us with an extremely detailed proposal, one in which we knew we wouldn't be "Nickel and Dimed" to send the cost of the project out of control. He held our hands throughout the project, was always available, explained every detail along the way, dealt with problems as soon as they arose and met every expectation we had. All of the subcontractors he used were on time, worked diligently and cleaned up the site at the end of each day. The quality of their work was first rate and the project was completed earlier than expected. Sterling Ridge, Spencer, and all the Sub Contractors were 100% trustworthy, not only in their personalities, but in THEIR WORK!

Spencer Cosgriff has managed three projects at our home in Saddle River. The largest of the three involved modifying the structure to permit installing an elevator; completely updating two bathrooms; rebuilding a walk-in closet, and adding molding upstairs and down. We were delighted with the relationship. Spencer is outstanding as a project manager and communicator. His work is of the highest quality, and he is 100 percent reliable.
