"We highly recommend US Waterproofing. Unfortunately, after repeated issues (we’ve had water getting through a basement door, water backing up from drain/sewer pipe, foundation cracks – all which were addressed) we now have had issues with hydrostatic water pressure delivering a great deal of water to our finished basement. Only one solution – drain tiles and sump pump installation. US Waterproofing was outstanding, every step of the way. They communicated clearly what was needed, and much to our surprise, what was not. They did not ever try to sell us anything that was not needed – only what was – installation of drain tile, window well drains, sump pump, and all work related. All of the crews involved were outstanding – in particular, the crews installing the drain tile and sump pump. The supervisor clearly and concisely explained every step – and when issues arose, they were dealt with promptly. The teams removing drywall and reinstalling also did very good work, and were very responsive. Everything was done correctly, and on schedule The work is now complete – and the basement is back to normal. I commend USW on all facets – they explained everything, did not try to oversell anything, and were responsive to issues as they arose. All the way around – sales, customer support, install teams – outstanding. If you have an issue with water in your home, please consider US Waterproofing."

"Project: Radon Mitigation Jordan explained what was being done for the project. He was very thorough in making sure the crawl space would be sealed and vacuum was proper in the crawl and basement. I would recommend Gardner Environmental to anyone needing Radon mitigation work."

Customers say: Quality work

"Very pleased with the prompt, friendly service. Very efficient and told me exactly what had to be done and what it would cost in advance. The old, limed up water heater had to be a bear to haul up and out of the basement. It gives me peace of mind knowing that the appliance was installed correctly by an experienced plummer and that it will last for many years to come."

"The work Everdry performed was excellent and The team was very professional and helpful through the whole process. Even today they are just a phone call away with any questions or anything I have about the work they perfomed in 2021. Along with that I haven't seen a leak or anything the basement drier than it has ever been and I couldn't thank them enough for all they did. 10/10 would recommend to anyone who needs their basement waterproof or looked at."

Basement Waterproofing questions, answered by experts

While "dry" mode on your AC can help reduce humidity levels to some extent, it may not be as effective as a dedicated dehumidifier, especially in areas with extremely high humidity or larger spaces. Dehumidifiers are specifically designed to remove moisture from the air more efficiently, making them a better choice for tackling persistent humidity issues.

Yes, many repair services include reapplying waterproofing and UV-resistant coatings.

Standing water under your house can threaten its structural integrity. If water pools in your crawl space, it can damage the foundation and the structure above ground, causing wood rot, mold, and other problems. If you have a concrete foundation, standing water under your house can also make your foundation slabs crack.

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.

If you set up a dehumidifier, it will usually dry out your wet crawl space within 12 to 24 hours. Once the space is dry, it’s a good idea to take preventative measures to keep it dry. These include installing a French drain or other exterior foundation drainage system, installing a sump pump in the crawl space, and installing a vapor barrier in addition to leaving the dehumidifier running.
