Basement waterproofing and foundation repair company. Family owned since 1957 with over 300,000 dry basements. Free consultations. Lifetime warranties available. Award winning company.
"Good work in general; our basement no longer sees water for over 3 years now, which is the most important thing. But there were some real issues: The biggest issue is that USW did not adhere to local electrical codes, and did not arrange for a final inspection of the project. So we didn't find out that it wasn't to code until years later, and now it's a big hassle and minor cost to fix and get the permits. Ask your local gov yourself what you need to do for permits and inspections; don't rely on USW! USW said they would seal any foundation cracks found along the way; they didn't do this until I bugged the warranty dept about it (but they did do it eventually). USW sent someone out for the "annual checkup"... over 2 years after the install. It's a good thing they (eventually) did, because they discovered the backup battery wasn't charging. Now I know to check this stuff better myself. Prices also vary wildly and are kind of negotiable (I'd give more detail but I'm out of space)"

Basement waterproofing services FAQs
Due to the nature of basements, some level of waterproofing is necessary to prevent water from seeping in and causing damage. Some definitive signs that your basement needs waterproofing measures or needs existing waterproofing measures need to be updated include:
Water in your basement, including damp walls or puddles on the floor
Mold spots in your basement
Musty smells or odors
Warped doors or walls
Cracks in walls
Insect issues, such as cockroaches and termites
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.
Damp proofing and waterproofing are both methods to help keep your basement dry. Damp proofing keeps soil moisture from entering your basement, which is helpful since your basement is underground. Waterproofing, however, keeps both soil moisture and liquid water out of the basement, which is essential, especially if you live in a wet environment. Because it’s more protective, waterproofing typically costs more than damp proofing.
Several factors dictate if you should waterproof the interior or exterior of your basement. Waterproofing the exterior of your home is a great option if you use your basement for storage, as it provides the most protection from water and water damage. If you prefer work done outside of your home versus inside, exterior waterproofing is best for you. However, interior waterproofing is often less expensive since the area is easier to reach and requires less labor.
The cost of basement waterproofing is $4,950 for the average homeowner. However, you could end up paying between $600 and $14,000, depending on factors like basement size, waterproofing method, and the region you live in.
If you live in an area with heavy rainfall, you might be paying more for waterproofing than if you lived somewhere drier since waterproofing contractors would be in high demand. Likewise, a 500-foot basement costs between $2,500 and $5,000 to waterproof, but that price rises significantly for a larger basement.
