"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)"

"I wish all the contractors on this basement project were as good to deal with as Family Waterproofing. Throughout the whole process, communication was good. Ken the owner was responsive and patient in answering all my questions and addressing concerns. They prepared a detailed contract of all work to be performed, and did what they said they would. I like that they did an exploratory dig after signing the contract to make sure we had a solid plan and avoid any surprises during installation. There was an area under the basement stairs and an old cistern that required a creative solution. They came up with a solid plan that didn't add extra cost. I asked them to pour some extra concrete under the stairs which wasn't included in the contract, which they did for a good price. The crew was friendly and had a good natured camaraderie on the job. The overall cost was very fair and we received great service and quality. They are honest, care about their customers and want you to be happy. Now I'm looking forward to a big rain!"

Basement Waterproofing questions, answered by experts

The most cost-effective foundation repair is using masonry patches and sealants to seal foundation cracks and offer some support to prevent further damage. These methods are used to fix minor foundation cracks quickly. However, they’re not suitable as a long-term solution, and they only offer minimal stability. On average, masonry patches and sealants cost $500, but a sealant like an epoxy crack injection can total over $2,000. If you’re handy and only looking for a temporary solution until you contact a local foundation repair contractor for a more permanent one, you can save hundreds by DIYing this repair.

The primary reason homes have crawl spaces is so the foundation can reach down below the frost line to avoid dangerous soil movement and structural damage when the ground freezes. They’re more popular in colder climates where the ground freezes down to a few feet, and slabs are most popular in warmer areas where there is no frost line. Crawl spaces also provide a space for utility lines to run where they’re at less of a risk of freezing.

The best way to waterproof a basement is to install a properly functioning gutter system and a French drain around the outside of the foundation. The best solution for your home could involve other waterproofing methods that resolve the problem unique to your situation. Depending on your soil type, climate, and other factors, that could include sealing, landscape alteration, interior drainage systems, and more.

While it’s possible to seal a foundation yourself, it’s not recommended, as it’s a tricky and labor-intensive job. Foundation sealing is best left to the pros to save yourself time, remove the risk of doing it wrong, and keeping yourself safe. Call a foundation repair professional near you to see what the job will cost.

Water can seep into porous materials like wood beams, floor joists, and roof rafters within minutes, but they’ll need to see prolonged exposure before you have structural damage. Mold can start growing within 24 hours, and mold can eat away at the structural components over time. Wood rot is more of a concern, though. Wet and dry rot are fungal infections that set in in moist conditions and rapidly deteriorate wood, causing major structural damage within just a few months in some cases.
