"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!"
