"Initial work was acceptable, though they left a significant mess afterward. The real problem began with their ?Warranty,? which must be renewed yearly. My elderly mother missed a payment or two because no reminder was ever sent. When we tried to resolve the issue, Anthony (Tony) L. was extremely aggressive on the phone. Tony L. insisted we would need to pay $3,000 to recertify the work. When we asked about installment payments, he said ?No.? When we asked if they could set up automatic withdrawals to prevent future missed payments, he again said ?No,? even while boasting that they are a national company?apparently one that can?t manage automatic billing. When my elderly mother mentioned contacting the BBB, he threatened to sue her. He then made repeated calls to me and threatened to ?make trouble? with my employer. It is impossible to recommend a company that tolerates this kind of behavior from one of its service managers. Avoid this 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)"

"Dale was very thorough in his examination of my situation and gave me clear explanations of what was going on. Other firms that quoted the work insisted that the entire basement needed to be done. Dale said that we only need to fix what is leaking. Cost to do that was one third that of other bids. Crew was on time, prompt and thorough. I would definitely use this firm again."

Basement Waterproofing questions, answered by experts

Crawl space encapsulation can make repairs more complicated, particularly if you have plumbing or wiring surrounding your crawl space area. Additionally, some home designs benefit from the additional airflow that crawl spaces with vents provide. Vents are no longer an option after encapsulation. Always talk to your crawl space contractor to ensure the pros outweigh the cons before investing in the installation.

It’s normally possible to stay in a house with water damage, but it depends on many factors. If the water damage is minor, like from a small plumbing or window leak, there’s minimal risk to you and your family members, especially if you catch it early. Major water damage from flooding is more likely to lead to mold growth and electrical issues, which means it’s safer to relocate until you have a professional dry out the area and treat the mold.

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.

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.

If there is standing liquid on your concrete, remove it before attempting any of the above cleaning methods. For small amounts of water, use rags, a bucket, and a mop. For larger areas of liquid, lay down cat litter or baking soda to soak up the water first. If you have extremely large pools of water sitting on your concrete, break out the wet vac and get to work.
