"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!"

"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 questions, answered by experts

Mold and mildew are the things in basements that actually cause the musty odors, but moisture is the underlying issue that causes mold and mildew growth. Addressing moisture and water problems and then removing materials that are moldy are some of the best ways to get rid of the musty odors. Preventive measures after that—like installing air fresheners and a dehumidifier—can help keep musty odors from returning.

The easiest methods for waterproofing your basement include installing a gutter system to direct excess runoff away from your foundation and grading the soil away from your home to pull water away from the concrete. In some cases, these methods alone can be enough to eliminate water intrusion and moisture problems in your basement. If you have excessive rainfall in your area, though, you might need to employ more complicated solutions, like installing a French drain and a dehumidification system inside.

No, everything doesn’t get wet if the bathroom is well-designed and the fixtures are properly installed. It’s important that the floor of a wet room drains correctly, and proper waterproofing and slip-resistant flooring are used to avoid creating slipping hazards. Since the shower isn’t housed in an enclosed space, you’ll need to make sure the towel rack and toilet paper holder are placed in areas where they won’t get wet.

You can seal a concrete slab by cleaning the surface, filling in any cracks, etching the surface, applying a sealer, and letting it dry. Concrete slabs don't typically need sealing, but you can use a topical concrete sealer if you notice signs of water damage. If you haven't already fixed the cause of the leak, then you'll want to repair the plumbing before you seal a concrete slab.

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.
