"I bought the Big Deal which was just for a single top coat to reseal the deck surface.  However, my deck was in a little bit worse shape than the deal allowed.  However, Ryan was awesome and added in sanding and then did the reseal for no additional charge.  The surface is not perfect but that is due to the rough pre-condition it was in and not his fault.  Shortly after the reseal the deck drains started leaking in to the garage below.  Ryan and crew came out again to fix the drain at no additional cost.  Again, this was not in the deal I bought but they provide such great customer service.  I would definitely use them again and will recommend them to friends and neighbors!

"The whole process was very smooth. They came out and spent a couple of hours assessing the problems...turns out we had several. The water heater burner had failed and was under warranty. But they also discovered our pressure regulator had failed, our gate valve was frozen, and we had a pipe leaking in the wall! They found the necessary part for the warranty repair and drove 50 miles each way to get it rather than make us wait 1-2 days for for the part to be shipped. They stayed until all the problems were resolved which was greatly appreciated! (My wife and three daughters were not relishing cold showers!)"

"I did not get the service from them. Their estimate for that job was extremely expensive and over price. I had to go with another vendor for half of that price with EXACT same steps to address the issue as they had offered and with great outcome. They were however very professional and made the diagnosis which I paid for ( very expensive) but I had to pay for that. I must say their diagnosis was very thorough."

"Will and his team at CXC did a great job replacing a failing stem wall perimeter foundation on my 1920s mid-city home. I bid the project out to six different contractors. His bid came in close to most and it became quickly apparent that his crew would delivery the highest quality and integrity to the job. His ability to accommodate my scheduling needs, the crew's many years of experience and overall professionalism, and the quick communication from the office administration all resulted in a great experience. A big shout out to WILL (Owner), CELSO (Foreman), and ROSANNA (Administration). Word of advice, get multiple bids and always verify general commercial liability insurance and that it covers the type of work that is going to be done. CXC's was easily verified...others were not and in some instance foundation repair was not even underwritten into their policies. CXC is BBB accredited, many others are not. I would not hesitate to work with Will and CXC again on my future projects."

Basement Waterproofing FAQs, answered by experts

Yes, if your crawl space is prone to humidity, a dehumidifier can help keep it dry. For use in a crawl space, you’ll need a high-capacity and high-efficiency dehumidifier with built-in air filtration. It’s also wise to purchase one with a self-draining feature. Otherwise, you’ll need to climb into the crawl space to empty the dehumidifier.

Interlocking garage tiles made with PVC are the most effective for garages with past issues of humidity and flooding because damp concrete is not suitable for paint. Epoxy coating is also water-resistant and can prevent mold buildup. Finally, porcelain tiles are a wonderful option for wet conditions if your budget allows.

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

Water leakage through window openings is much more common in older homes, but it can also create issues with window frames that are improperly installed. If left unattended, water buildup can cause damage to surrounding fixtures, lead to harmful mold, and compromise the architectural integrity of your home. The potential damage that a water leak poses makes investing in weather- and water-proofing your window frames entirely worthwhile.

A walkout basement is considered to be partially below grade because at least one wall is entirely exposed. In some cases and in specific municipalities, inspectors and appraisers will still count walkout basements as below grade, which means the space can’t serve as living space or be rented out. If you intend on using the area as living space or a separate apartment, you should check with your local building department to make sure it’s legal to do so.
