"Willie and his team did fantastic work. After contacting numerous other "foundation experts", Willie provided the best plan and backed it up with his overall knowledge and certification/training in basement/foundation repair. He and his team do great work and take no short-cuts when it comes to the overall quality of the work. He also was very flexible when other requests were made and he gladly accommodated. He has a passion for his business, customers and takes great pride in his work. The basement and porch are now fixed and look great. Best of all is that we have confidence the work performed will last."

"took most of five days. patriot crew went above and beyond doing things like depositing excavated dirt to build a berm and raising a low spot in another part of the yard. they also hauled off concrete debris that was underneath the house and left us some river rock that wasn't used on the french drains. ventilation system appears to be working as advertised. we were so pleased that my wife baked them some chocolate-chip cookies. they were also pleased."

Basement Waterproofing FAQs, answered by experts

A sewage smell in your crawl space is usually from a damaged or clogged pipe leaking sewer gasses or actual sewage underneath your home, but there are some other common causes. Moisture, from poor or damaged encapsulation or a malfunctioning sump pump, can harbor mold and bacteria, causing a musty smell. Pests can also get stuck in your crawl space and die, which causes a sewage-like odor.

In nearly all cases, you are required to install a vapor barrier in your crawl space. However, local regulations will change based on the local climate and the crawl space's susceptibility to moisture. Even if a vapor barrier is not legally required, it is often a good idea to keep your crawl space dry.

Several types of insulation are effective for crawl spaces, with spray foam and rigid foam boards being two of the best options. Closed-cell spray foam insulation is a strong choice because it effectively repels moisture, resists biological growth, seals the air, and provides excellent thermal protection, especially in hard-to-reach areas. Rigid foam insulation boards are another excellent material as they insulate well, resist water damage, and will not settle over time like fiberglass or cellulose.

In most cases, it is safe to live in a home with minor foundation problems, but you should not let the issues persist. Virtually all foundations have small cracks from normal settlement, which are not a structural concern but should be sealed to prevent water intrusion. However, major damage—such as large structural cracks, sinking foundations, or bulging walls—can make a home unsafe. Other issues that can pose safety and health risks include poor indoor air quality from mold or pests, uneven floors, and rotten beams or joists. It is always best to have a foundation repair expert or structural engineer inspect any issues to determine if your home is safe to live in.

Yes, if your crawl space is prone to humidity, a dehumidifier can help keep it dry. For use in a crawl space, you’ll need a high-capacity and high-efficiency dehumidifier with built-in air filtration. It’s also wise to purchase one with a self-draining feature. Otherwise, you’ll need to climb into the crawl space to empty the dehumidifier.
