"Everything about this repair job was wonderful - from Brad giving us the bid (and explaining exactly what would be done), to Will and Ree (sp?) doing the excellent work. Everyone was courteous, professional and left everything spotless. And the cost was surprisingly lower than I thought it would be."

"Andrew did a fantastic job. He was very knowledgeable and explained the pros and cons of the different waterproofing methods he recommended I apply to my basement foundation to make sure it stayed sealed long term. He was very professional, a good communicator, cleaned up after himself, and made sure to provide updates throughout the work. He even repaired a cracked portion of my sewer while installing a sump pump. Would highly recommend! Not a lot of waterproofing companies out there like Affordable that are a one man show, which is the best part. One man job = one way communication and responsibility. It hurts me not to give him a full 5 stars, but the only minor con I can bring up was how the work was some charges tacked on at the close of the project, due to some extra cost he told me he incurred for the pipe/connections needed to repair/replace the cracked pipe. The labor materials for repairing the damaged pipe were listed on the original firm bid I received before the project started. As I said this was a VERY MINOR con and I feel you will not find a better contractor out there to replace Andrew for your waterproofing needs!"

"The technician that did the service, let me know specifically one thing that turned not to be possible. I would never known, because the issue was below the ground. He also gave me post sales advice to recommend to my A/C who would be installing a unit near the repair."

Basement Waterproofing FAQs, answered by experts

Since basements are prone to water and moisture issues and the resulting problems can be expensive to repair and potentially damaging to your home, basement waterproofing is almost always worthwhile. Even for homes that haven’t experienced water infiltration, waterproofing the basement is insurance against facing expensive repair bills in the future. All basements will leak at some point, so fixing drainage issues and taking steps to prevent moisture and water infiltration is wise.

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.

If you notice standing water under the deck after rainstorms, you may need a drainage system to efficiently move this water. You do not want standing water to rest against your foundation or against support posts for the deck, as this could cause significant structural problems over time. Make sure the area has proper grading, too.

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.

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.
