"We paid close to $20,000 to BQ Basements to completely waterproof our basement. We still get water and they told us we need another sump pump installed at over $2,000. They guaranteed we would not get water after installation. Be aware they do not stand behind their work or honor warranties."

"Working with DJ from Groundworks (Select Basement) has been an outstanding experience. After struggling with various contractors who either failed to resolve our water issues or were unprofessional, DJ and his team truly stood out. DJ was incredibly helpful, patient, and responsive throughout the entire process. Our home is a ranch with 225 linear feet around the perimeter, and while other contractors insisted on installing a French drain for the entire length, DJ recommended a more targeted approach. He proposed installing the French drain for just 80 linear feet, focusing only on the areas where water intrusion was likely. His thorough explanations and prompt responses to all our questions were greatly appreciated. The workers arrived on time, maintained a clean work environment, and completed the job as promised. If we could give 10 stars, we would! Groundworks is a highly professional and honest company that didn't try to inflate the scope of work to charge us more. We wholeheartedly recommend them."

"They did it right & quickly. However, the price quoted to me was no where near the final price. They said they installed a secondary pump which added $1450 more!

Basement Waterproofing questions, answered by experts

Waterproofing or encapsulating protects against moisture, preventing mold growth and structural damage. These services also enhance energy efficiency and improve air quality by keeping humidity levels in check.

One handy thing about whole-house dehumidifiers is, once installed, you don’t have to worry about placement or changing the dehumidifier’s position. But if you are using a portable dehumidifier, we suggest keeping it away from walls, vents, and furniture. It needs a central, unobstructed spot with access to lots of air to do its job.

Signs include persistent dampness, mold or mildew presence, musty odors, and visible water stains. If any of these occur, it is advisable to contact a professional for an inspection.

You can DIY basement waterproofing in some ways to help save on the overall costs. If your basement isn’t experiencing a lot of water but is noticeably humid, you can try running a dehumidifier that will pull the excess water out of the air. If you notice water leaking due to outdoor drainage issues, you can add downspout extensions to keep rainwater away from your home. 

However, if the problem is more severe and requires a more extensive solution, it’s best to call a basement waterproofing professional to assess the treatment you need and install waterproofing safeguards properly. Since keeping water out of your basement is important, ensuring this job is done correctly the first time is best.

Yes, you can enclose your crawl space. Enclosing your crawl space can promote energy efficiency and reduce the risks of pests and mold by limiting factors like humidity. It can also reduce heat loss, which is why doing so for the winter can make your home more comfortable.
