"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

Yes, you can finish a basement that leaks, as long as you address the leak first. Before finishing a basement, you’ll need to repair any cracks in the walls and waterproof the basement to prevent future leaks. It’s much harder to clean up a water leak from a finished basement than an unfinished one, so preemptively addressing any leaking areas prevents expensive repairs in the future.

While "dry" mode on your AC can help reduce humidity levels to some extent, it may not be as effective as a dedicated dehumidifier, especially in areas with extremely high humidity or larger spaces. Dehumidifiers are specifically designed to remove moisture from the air more efficiently, making them a better choice for tackling persistent humidity issues.

A plastic vapor barrier should completely cover your basement to prevent water from penetrating through the walls. This typically goes before installing insulation to prevent moisture from building up and becoming trapped on the inside of your insulation, where it can collect and lead to mold damage. Installing insulation after the vapor barrier allows for any moisture to exit the walls for better ventilation.

There are several small, inexpensive upgrades you can make to upgrade your basement. Although you still need to adhere to building codes and obtain permits when necessary, you can complete small but mighty tasks like painting the masonry walls and installing entertainment devices to make the space more usable. 

A leak under your foundation from a water supply line or sewage line is likely to lead to water pooling on certain areas of your property during rainfall, abnormally fast-growing or green grass in certain sections of your lawn, and differential settlement of your foundation, which can result in large foundation cracks, windows and doors failing to operate properly, a wavy or sloping roofline, or damages or irregularities in your interior walls, including cracks and bulging. If it’s a plumbing line embedded in your slab, you’ll also likely notice above-average water bills.
