"I have had two issues since they installed the new sump pump and irrigation. Issue number one was water still getting passed the new concrete. The other issue is that the new concrete was not level at all which has caused issues with the new flooring I installed. However, their customer service is top notch and will work hard to take care of you."

"The workers were on time. Very efficient. They did a blower door test and found the air leaks and insulated these areas. Blew installation above the garage, cleaned out the crawl space and put new installation there and basement. Found a water leak from my toilet,Thank goodness. Covered everything in the basement and swept and cleaned up after. I would recommend them!"

"If you need reliable contractor, my strong recommendation is Palm Construction. I hired them to build a deck and they did phenomenal job. Ray and his brilliant team made this project simple and non painful. I worked with many contractors and this was my best experience. They also charged at the end very reasonable final price, although quality of materials is superb. I can't recommend enough!"

Basement Waterproofing questions, answered by experts

You should always hire a structural engineer or a professional and licensed foundation repair company for crawl space repair.
