"Let me start by saying that I would ABSOLUTELY recommend Weather – Tite Waterproofing to anyone who has water in their basement. They were incredibly professional and did top notch work. I had been getting water in my basement on and off for years. After fixing the gutters and fixing the roof it was time to address the basement. I consulted with three different Angie’s List companies (all very highly rated). Each company had a slightly different price but more importantly a different approach to resolving the problem. I picked Weather – Tite because I was comfortable with the approach that they proposed, and the price was in line with the other quotes. The work took 2 days. Day 1 was spent digging the trenches around the interior of the basement. Day 2 was spent putting in the stones and piping and hooking it all up to the sump pump. As you can imagine, putting in a drainage system is messy work – you would have been none the wiser – my whole house was spotless (including the basement) – no dust anywhere. The work was so professional that I had them come back and put up the baseboard and sheet rock. I can happily say that since the work has been completed, we have had quite a few heavy rains, and my basement has stayed dry."

"CT basement did a phenomenal job finishing our basement and we could not be happier with the results. They made every step of the process from design to the finished project simple and straightforward, everybody was easy to work with and made our opinions and needs the top priority and they were able to perfectly translate our vision into the final product. This was a fairly large project involving finishing 1200sq ft with an office, gym and full bathroom and their experience and expertise was obvious. They definitely understand the specific needs of a basement while making it look like any other room in the house. We would use them again in a second, we’ve even been joking about tearing down the rest of the house and just living in the basement!"

"Dean and his crew were professional, reliable, extremely neat/clean and went above and beyond, often, to make the sure work was completed to my satisfaction. They did small things not even required to make sure the entire basement area was much more than even expected. The basement has never been so dry in the 40 years I have lived here. I would hire them again in a heartbeat."

Basement Waterproofing questions, answered by experts

Preventing future basement flooding often involves installing sump pumps, improving drainage, sealing foundation cracks, and maintaining gutters. Costs vary, but preventive measures can range from a few hundred to several thousand dollars, depending on the solutions chosen. Investing in prevention can save you money on future flooded basement cleanup costs and repairs.

Foundation repair uses methods such as underpinning, slab jacking, or application of hydraulic piers. Each technique is chosen based on structural needs, soil conditions, and damage extent, ensuring a stable and secure foundation.

It is better to have a crawl space that is tailored to the outside temperature, your needs, and the season. For example, it is much better to have a vented space when it’s very hot outside and your AC bills are sky-high. Conversely, when the temperature drops and humidity rises, it is almost always better to have your vents shut and covered if possible.

Walkout basements cost more than other kinds of basements, and can also increase your risk of leaks as well as a loss of insulation, leading to higher heating and cooling costs. Improperly installed walkout basements may lead to structural issues with your foundation, so ensure you’re working with a contractor who has extensive experience with this kind of basement.

Although the two terms are closely related and often used interchangeably, pier and beam foundations and crawl spaces are different things. A pier and beam foundation is made up of concrete piers and wooden beams and creates a space under the home known as a crawl space. There are several types of foundations that create crawl spaces, often collectively known as “crawl space foundations,” but the crawl space itself is separate from the foundation.
