“Salvador did our decking project. He is an honest guy with great work quality and work ethic. A true stand up guy when we encountered decking issues. Please give Salvador a call before you hire anyone else!”
“We had a failed balcony waterproofing and needed to tear down to plywood. Salvador is the owner and he takes pride in his job. He is very knowledgeable about waterproofing. He does the work himself so you know job is done right. Salvador explained each step and answered all my questions. He is on time and quick to reply if you call him. He finished job on time and cleaned up. Highly recommend Salvador if you need waterproofing.”
