Deck or Porch Repair
Larry did a beautiful job on our new deck. His work ethic and his and his team's (Danny) craftsmanship went beyond what I could have asked for! He said the job would be completed in 10 days, and it was. He quoted a more than reasonable price and stuck to that price. Larry is the real deal! If I could give him 10 out of 10 stars, I would!! Hire Thornhill Construction, you will not be disappointed!!

Owner Larry Thornhill provided a comprehensive quote at a more than fair and reasonable price. He and his carpenter, Daniel, completed the work exactly as quoted in a timely manner. Daniel was extremely conscientious and kept the work area clean as he went along. We were extremely satisfied with the result and we would highly recommend Thornhill Construction to anyone in need of that kind of work.

I am so glad I found Larry Thornhill and his team. Larry and Danny went above and beyond on this job. The stairs look great and are so much safer than before. I would highly recommend their team to anyone.

Larry did a great job and we had very good collaboration throughout the entire project. He listed to want I wanted and my ideas and solved a few ugly problems along the way that we didn't anticipate (it was a rebuild and he had to deal with unforeseen structural issues) without nickel and diming me for everything that popped up, and changes along the way I requested. The price was very reasonable, and the project was completed faster than I thought. And the deck looks fantastic, Great guy and friendly crew, my wife and I had lunch with them every day!

This was their second project for me. I was thrilled that they were available to replace my old porch with a beautiful new composite porch that matches my composite deck hey built last year. I highly recommend Larry Thornhill and his crew. He delivers a quality product for a comparable pice.

Larry was very professional. He came out and viewed our project and was able to give us a ballpark figure on the spot. He bid the project and the time it would take to build. He was spot on for both. What we really loved about the job was the quality of work. We added a ramp on the side for future wheelchair access . Larry and his guys constructed it perfectly. From where the ramp began on the pavement to where it ended at the deck, it was smooth. The whole deck is beautiful. We are delighted with Larry and his team's work. We would recommend them to others without reservation.

Larry and his crew did a fantastic job on replacing our front entry deck and stairs. Because we are on a hillside, the deck reconstruction was fairly complicated but the finished product turned out great ! We are very happy we chose Thornhill Construction and would highly recommend them to anyone needing work done !

Larry and crew were all business. They removed and installed a new attic ladder that was fairly complex, and the old ladder had to be removed prior to installing the new one. He upgraded the ladder , and still cosmetically made it look good, and like it had been there. Very dependable, and got the job done in almost exactly the estimated time. He and his crew answered all questions professionally. We would recommend him for any work that he said he could get done.

This is the second deck project Larry Thornhill has completed for us. We originally hired him after seeing the quality work on another job he completed in our community. He is super-dependable, on time, keeps the project moving forward and pays attention to details. He provides a written estimate before the project begins and gets approval for any changes or additional charges before proceeding. We recommend Thornhill Construction.

Larry Thornhill & his crew did an absolutely wonderful job on rebuilding our deck. Larry kept us informed on all stages. He set a work schedule for each day & finished the deck on the day he said he would. On budget & on time. Larry also made suggestions for improving our design and the deck is amazing and better than we expected. His crew performed quality workmanship and we are very satisfied.

Friendly and extremely competent in their work. I had an idea of want I wanted and Larry designed it better than I dreamed. The team found dry rot when they removed the old deck . They cleaned out the area, replaced a beam and fixed the siding on the house before completing the deck. They delivered on time and cleaned up nicely when they were done. I would highly recommend Thornhill Construction for any deck work needed! They go above and beyond regular construction companies!
