"They are this good and I am just that lucky! Saw a leak this morning at 830 AM. Called the main number, Marcus called back quick, sent pictures, installed new one and hauled off the old one by 230-3. Great Team. With that quick of a response and completing the job within the same day, it was worth every penny. Tried to upload photos but they were too big Highly recommend PLP"

"Excellent. Honest and quick work. Mr. King was able to get someone out on short notice, to shim/shiv the piers. They performed a full scale cleanup last year, and I will only use Basement kings for any of my crawlspace work. Best in Texas!"

Basement Waterproofing questions, answered by experts

Proper drainage prevents water damage, mold growth, and foundation settling, protecting your home’s structural integrity.

The least expensive basement waterproofing methods include grading soil away from your home, installing downspout extenders on your gutter system, and applying a waterproof paint on the interior of the foundation walls. Installing a French drain is a relatively inexpensive method if you do the work yourself, although it’s labor-intensive and can be challenging to install properly.

Damp proofing and waterproofing are both methods to help keep your basement dry. Damp proofing keeps soil moisture from entering your basement, which is helpful since your basement is underground. Waterproofing, however, keeps both soil moisture and liquid water out of the basement, which is essential, especially if you live in a wet environment. Because it’s more protective, waterproofing typically costs more than damp proofing.

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.

“Basement waterproofing” sometimes refers to applying a waterproof sealant to basement walls, in which case you would use a waterproof paint, often made of latex. However, there are many methods you can use to waterproof a basement, including exterior drainage systems, interior drainage systems, dehumidifiers, and more. As such, the materials you use can vary depending on the methods you use.
