what clients say

Honest work, clear communication, and finishes that last

The team performed significant structural work on our house with no fuss opening us between kitchen and dining room and changing the layout of our downstairs. Raphael handled all of the trades for us and had good recommendations for suppliers. The finished result is fantastic and we have had so many compliments on it. We feel the work was fairly priced and overall we would definitely recommend using them.

Steel beam installation — structural issue caught early

“Raphael and his team initially came to do some minor kitchen and floor repairs after we purchased a new home. Raphael discovered a major structural issue, and within the hour had his structural engineer onsite inspecting the building’s integrity.”

Saw past the obvious solution

“Old built house — had other contractors look at the job. Others said rip everything out. Raphael saw past this and suggested we could retain key features from the old-style building. Very high attention to detail.”
