"Jeff came out and did exactly what is advertised on their website: inspected and educated. Excellent service with a depth of knowledge. My wife and I have owned a house for almost a couple years now that is 62-63 years old with a crawl space. It had some foundation work done sometime before we took ownership and we just wanted some peace of mind that everything was still solid. Jeff came out and ended up just doing a cursory inspection since my wife and I didn't need anything official, just a professional eye. I followed Jeff around as he was pointing things out. Thankfully there was nothing of concern, just points of interest, and a lot of education. At the end of it all, my wife and I are much more confident in the backbone of our house thanks to Jeff and the Foundation Professionals of Colorado."

Basement Waterproofing questions, answered by experts

Depending on the severity, a slab leak can go undetected for months or even years, especially if you don’t carry out routine foundation inspections to find foundation leaks early. However, minor leaks are likely to turn into more severe leaks over time, so you might notice increases in water bills and issues with yard drainage, even if the problem is minor.

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.

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.

A vapor barrier keeps moisture out of the crawl space, while insulation reduces the amount of unconditioned air—and sometimes moisture—that enters the space. Coupling a vapor barrier with insulation can help prevent humidity and related moisture damage in a crawl space while also making your home more energy-efficient. Just be sure to use insulation that won’t get damaged from moisture, like rigid foam board or expanding spray foam insulation.

Yes, cleaning a crawl space is worth it. You might think you can ignore the area since it’s out of sight, but doing so can lead to pest infestations, mold, and other problems. Crawl space cleaning costs between $0.50 and $4 per square foot, but the cost to deal with pests or mold would be much higher.
