what clients say

People choose us because we’ve proven to be the best!

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.”

Andrew Liberstein

Regular client

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.”

Sam Smith

Regular client

Built genuine trust

“High quality finish, very transparent and honest. Built trust with myself. He knew what he was talking about and reacted positively to questions. Was accommodating when changes were made — went above and beyond given the situation we were in.”
