Exceptional Work and Service from Cornerstone Construction

We recently completed a home addition and in-law suite with Cornerstone Construction, and we couldn’t be happier with the outcome. From start to finish, the entire process was smooth, professional, and stress-free.

Steve, the owner, was outstanding to work with—knowledgeable, responsive, and truly committed to delivering a high-quality result. He took the time to understand our vision, offered thoughtful guidance throughout, and ensured every detail was handled with care and precision. His team was courteous, skilled, and consistently went above and beyond to keep the project on track and on schedule.

The new space looks incredible and functions perfectly for our needs. It blends beautifully with the existing structure and feels like it was always part of the home. We’re especially grateful for the care taken in designing a comfortable and accessible in-law suite for our family.

We highly recommend Steve and Cornerstone Construction to anyone considering a home addition or renovation. Their craftsmanship, professionalism, and customer service are truly second to none.

Thank you again for a fantastic experience!

Summary: The best we've ever worked with. Absolutely amazing. Easy to work with and even another contractor friend commented how high quality their work was.

Details: We were in the middle of quoting out a good bit of random jobs when we had a pipe burst in our home. This increased the amount of work needed. We were so impressed with Stephen during the quoting process that we asked him to come back out, change some things, add a bunch, and requote. He heard us out and didn't mind the changes at all, and with the larger job gave us even better pricing, which was already fair and in line with other quotes. There ended up being about 20 different projects, including two new bathrooms, sheetrock installation/painting, new light fixtures, new electrical outlets, Trex stair handrails outside, wooden stair handrails inside, and a bunch more. The team was very respectful, kept things clean at the end of each day, disposed of everything properly, and did fantastic work. Any little things I'd point out they'd take care of without any hint of it being too much. When some of the grout work in one bathroom had issues, they fixed it without me even asking (my floors are not exactly level from the house shifting over the years, so it was a difficult job). When one thing went wrong a few weeks after they finished, they came back and fixed it again without any issue. I was in constant communication with Stephen and/or his team, and I couldn't have been happier with the process or how things turned on. Everyone that comes over comments on how amazing everything looks. I've already recommended Cornerstone to a handful of people, and will use them again in the future.

Cornerstone Construction did a great job rebuilding our deck. He gave us options in a written quote, and the work was done quickly. It looks great and we’re very happy.

Recently purchased a new home and I knew I wanted to finish the basement and create an In-law suite. I got quotes from a few companies and decided on Cornerstone. I had a vision for months on what I wanted to do with the space and they made it a reality. Fair prices, they completed the project way faster than I ever thought, and we were in constant communication the entire time. All the staff was great, I'd definitely use them for my next project.

Steve and his crew were very professsional and had attention to every detail when my bathroom was recently remodeled. I had so many questions before the project was started, but with Steve’s guidance, I quickly felt reassured. I was so delighted when the bathroom was completed. I only wish that I had remodeled a few years ago. I will definitely refer my friends and family to Cornerstone Construction.

Working with Stephen and his whole team was absolutely amazing! He regularly communicated with me, sent me photos, and kept me updated with the work. He was very timely, respectful, and patient about what I wanted, as I was new to this whole process. He also gave me recommendations as to what would look good. I would highly recommend them for any house project.

I personally believe that when one has had value in service from providers, then it should be rewarded by letting others know should they be looking for said experience themselves. I dont give 5 stars but this experience is worth it.

I had the professional assistance of Stephen, Marlon and the crew from Cornerstone Construction when navigating through what has been a kitchen nightmare for me and my family. They seem to somehow took our problems and made it their own and that gave us the good feeling of thongs to come.

ISSUES
i had a water damage kitchen that proves to be more of a gut job than a quick fix. Stephen was able to quicky access the damage areas to help us start the insurance claim process and created a timeline process for start to finish completion.

PRO
The team was timely, professional and patient. They quickly remove all damages and did a fabulous job of cleaning up.

When we ran into material issues, delivery hiccups and damges that would set us back weeks for the cabinet, Stephen and his team quickly provided solutuons that turned out to be cost effective and efficient to the build plan.

CON

The only negative was actually a positive on cornerstones end as they patiently worked with us as clients while we navigated some tough issues. It did extend the timeline and we ran into delays but like true professionals they were able to get us scheduled in between and the job completed once we got everything situated.

I honestly am grateful to have stumbled on Cornerstone in our search but even more grateful that it is lead by a responsive and fully engaged owner in Stephen, who responds to every call and addresses each concern no matter how small.

Thank you Cornerstone Construction.

P.s we live in that kitchen now

Stephen and his team were FANTASTIC to work with. They did much needed repairs to our sunroom -- ultimately replacing the entire ceiling and installing a new door. They also built a beautiful new lower deck and replaced the stairs to the upper deck. Throughout the multiphase project, Stephen worked with us , communicated effectively, and walked us through options. We will definitely call them again for future projects!
