Basement waterproofing and foundation repair company. Family operated since 1957 with over 500,000 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)"

Everdry is the Nations leader in basement waterproofing with 100,000 satisfied customers! We help you create dry usable space.

"We had a small leak that only happened in severe rainstorms. Instead of diagnosing this problem the salesperson wa ted to sell us their complete system. They painted a picture of a poorly constructed basement with many problems. We resisted but finally agreed this was s mistake, because the only problem found after tearing up our basement was a dead sump pump and maybe extra weep holes could have been put in the crock. The original basement drainage system was correctly installed to code. Now our perfect basement floor has permanent scars and we are still fighting the concrete dust leftover from the project. The workers also damaged our vinyl siding and stained it with some type of solvent when cleaning areas that were marred during work. They are probably solve severe basement problems, but we were definitely “oversold”. We made a regrettable error in trusting their expertise."

Basement Waterproofing questions, answered by experts

In perfect conditions—meaning, no overexposure to the elements without roofing material on top of it—an ice and water shield can last for decades. In fact, many come with a limited lifetime warranty because they should last for a long time. If, however, the membrane is exposed to the elements during building or if there is a delay in installing the roofing material, it might only last up to 180 days if exposed to the elements. The key is to make it a layer of protection and then protect that layer by installing the roofing.

If you decide to fill the space around your home’s foundation with landscaping materials, it’s important to consider the aesthetic as well as technical factors like drainage and protection from pests and the elements. Materials such as gravel, rubber mulch, concrete, and brick masonry are all good options.

Finishing an unfinished basement adds the most value, with an average return of 70% or $22,400. A bathroom addition in the basement will provide an ROI of 75%, but the higher cost will leave you with a lower actual return of $9,000, on average. Finishing a basement and adding a kitchen, bathroom, and bedroom to rent the space will leave you with the highest possible ROI, as you could see well over 100% if you rent the space out long-term.

The difficulty of adding a basement to an existing house can vary depending on the house’s location, the size of the basement, and the type and condition of the existing foundation. Adding a basement is a job best handled by the pros, so you’ll need to enlist professional help for this project.

Most houses will have vents in the crawl space. This allows for air passage and energy retention, which in many ways can help control the temperature inside the home. If you are able to consider the cost of a crawl space encapsulation, you may not need your crawl space vents at all.
