"I hired Jon initially to repair some water damage in the crawl space which affected a couple of the support beams. As he started working on the project he noticed some constraints that required a few adjustments to the original plan. Throughout the process he constantly explained the several available options and what the implications would be of choosing between them. To prevent future damage he also installed a French drain system to prevent water entering in the crawl space. As he was already working in the crawl space, we decided to also reinsulate the crawl space as the existing insulation was fairly old and not up to code. He was very flexibly in terms of timeline and did a great job in installing the insulation. This was a particularly challenging project due to the area size (over 4000sqf) and crawl space geometry. Overall I'm very happy with the work performed by Square 1 Venture group, I highly recommend then and would certainly work with them in the future. Great value and customer service!"

"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!"

"These guys did a great job on the drain cleaning and explaining to me how the drains were connected beneath and outside my home. I felt like the price was quite fair. I had gotten an estimate to re-do a french drain outside my basement after that experience, and I told them I would get back to them in a few months due to cost. It was a good price, but repairs are repairs, and most of them are expensive. I tried getting these guys out again a few months later, but I had a really hard time getting in touch with anyone. I was happy with the work from before, for sure."

"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

Brick is designed to absorb moisture, but it is also designed to let it evaporate as well. So in general, the goal shouldn’t necessarily be keeping moisture out but making sure it has the room to breathe. If you have excess moisture getting through your brick wall, it’s more likely that you have a crack or other issue at play that a typical sealant won’t fix. So, instead of investing in sealant, try repairing your brick wall instead.

Yes, usually you will need some kind of vapor barrier on the exterior walls when the framing is attached to concrete and masonry surfaces.

When doing any type of project involving mold, it's important to wear the right protective gear. You'll want an N-95 or KN-95 mask to keep yourself from inhaling mold spores, which can be irritating or trigger an allergic reaction in people with weakened immune systems. You'll also want to wear protective eyewear and gloves to limit your contact with mold.

Roughing in and connecting utilities are the hardest parts of finishing a basement, and they’re the parts we typically don’t recommend doing as a DIY project. Unfortunately, your finishing timeline can be extended by weeks while you wait for contractors and inspectors to install electrical wiring, plumbing lines, and heating/cooling equipment and carry out inspections.

A moisture or vapor barrier helps separate the warm air inside your home from the cold air outside of it. Without it, your walls could collect condensation, mold, or other damage. Check your local building codes to see if including an interior vapor barrier is necessary for your building project or renovation, especially for rooms that are likely to be humid, like bathrooms.
