"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

A crawl space is an area under the house that provides access to plumbing, electrical, heating ducts, and other HVAC units. Its purpose is to create a buffer between the ground and the living area, helping with ventilation, moisture control, and access for maintenance or repairs. Crawl spaces are most often seen in houses in North America which are built on concrete foundations versus other parts of the world where buildings are constructed differently.

Water can seep into porous materials like wood beams, floor joists, and roof rafters within minutes, but they’ll need to see prolonged exposure before you have structural damage. Mold can start growing within 24 hours, and mold can eat away at the structural components over time. Wood rot is more of a concern, though. Wet and dry rot are fungal infections that set in in moist conditions and rapidly deteriorate wood, causing major structural damage within just a few months in some cases.

Yes, basement insulation needs a vapor barrier due to its susceptibility to moisture seeping in from the outside of the house. You should install a moisture barrier before you install insulation or purchase insulation that comes prebuilt with a moisture barrier to avoid water damage in your insulation and costly mold and water remediation expenses. 

Brick is designed to absorb moisture, but it is also designed to let it evaporate as well. So in general, the goal shouldn’t necessarily be keeping moisture out but making sure it has the room to breathe. If you have excess moisture getting through your brick wall, it’s more likely that you have a crack or other issue at play that a typical sealant won’t fix. So, instead of investing in sealant, try repairing your brick wall instead.

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.
