"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)"

We are family owned and veteran owned (USMC). We provide professional basement waterproofing solutions that work within a family?s budget. We guarantee a positive experience in your moment of need. From the moment you contact us, you are treated as one of the family. We show up for our appointments on time, create a solution customized for your needs, and complete your project in a professional and timely manner. Our waterproofing solutions allow you to choose what you are most comfortable with, whether you are in need of a repair or interested in doing preventative maintenance.

"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

If a crawl space isn’t vented, there can be moisture buildup, which can lead to mold damage, easily destroying the foundation of your home. A closed-off crawl space can trap heat, which can be useful in the winter, but can also trap dangerous gases and prevent clean air from entering the home through the floorboards.

To ensure your basement walls are waterproof, it's crucial to address any existing moisture issues before finishing. Inspect for signs of water seepage, such as dampness or discoloration, and repair any leaks or cracks. Install a vapor barrier to prevent moisture from penetrating the walls, and consider waterproofing paints or coatings.

Proper drainage systems, such as interior or exterior waterproofing, can also be beneficial.

You don’t always need to install a dehumidifier in your encapsulated crawl space, but it might be a good idea in certain instances. If you notice obvious signs of condensation, mold, or musty smells permeating from your crawl space, a dehumidifier can help. It’s ideal for homes in humid areas.

In a worst case scenario, structural damage like rust on metal beams, rotting wood, and swelling on doors and windows can signal moisture problems that would benefit from a dehumidifier.

Crawl space encapsulation typically lasts between 10 to 20 years. If you experience a catastrophic event, like a flood, or poorly encapsulate your space with low-quality materials, it may only last a decade. Otherwise, as long as you properly maintain your crawl space, a high-quality encapsulation can last more than 20 years.

Yes, usually you will need some kind of vapor barrier on the exterior walls when the framing is attached to concrete and masonry surfaces.
