REVIEW US ON

We hired Harris & Sons to remodel part of our house and also build an addition. The project involved 3 bedrooms, 2 walk-in closets, and 2 bathrooms. Throughout the construction process, which had a few unforeseen complications, Harris & Sons worked to meet our expectations, gave us constructive options, and pushed to keep as close to the schedule as possible. They worked with us on controlling overall cost and understood and respected our financial capabilities and limits. In the end they gave us a beautiful and good quality home.

From our first meeting, Christian Harris stood out. Not only is he incredibly knowledgeable about construction and design, but he also brought a level of calm confidence that made us feel like our home was in the best possible hands. He took the time to understand our vision, walked us through every step of the process, and communicated consistently, something that’s rare in the construction world these days.

I met with Christian and a tall young man whose name escapes me, and was very impressed by their professionalism. They gave me a quote for remodeling after major water damage. Sadly I couldn't use them as I was fighting with my insurance company at the time!! I still think about the awesome job I KNOW they would've done for me and am still upset it never happened.

We had Brian and his team Marcos & Jackson put in a privacy fence for us. The work done was outstanding and the fence looks great. I’m overjoyed by the job they did dealing with the ‘less-than-friendly” rock pile we live on. The work was done efficiently, clean, and fast. I don’t think I heard one curse-word uttered. These guys are clean, professional, quick, and darn good at what they do! I couldn’t recommend them more and we’ll be calling them again to put in our deck! Thx guys!!!

This team did such an amazing job building my pergola cover and enclosing my deck. Very professional and quality work. All of their suggestions for design were great, and I would recommend them for any project.

We have worked with Christian and his team for numerous projects around our home for the past year. They built and stained a beautiful fence for us, and also built a paver patio and pathway in our backyard. They are consistently friendly, communicative, and deliver high-quality work. Their employees are considerate and helpful. They have excellent follow-through from start to finish, and are exceptionally priced. We would highly recommend this team and we will continue to utilize their skills around our home going forward.
