"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!"

"I saw them in the neighborhood, so I got their details and they gave me an estimate. They were re-repairing a crack from 20 years ago. They did their work and cleaned up afterward. I waited until after 3 or 4 serious rain storms before this comment. The basement still dry. No seepage through the cracks. I should have called them a long time ago."

"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 questions, answered by experts

Yes, slab leaks are fairly common, especially in older homes and places that are prone to earthquakes which can move home foundations.

Rigid foam board insulation is one of the safest insulation materials for basement walls. The panels offer a moisture barrier to prevent mold and mildew build-up. At the same time, this material is also fire-resistant, so you don’t have to worry as much about a fire breaking out as you would with spray foam insulation. 

Costs depend on the area's size and condition, damage extent, and chosen method. A professional evaluation provides a tailored estimate based on specific needs.

Permits may be required for major repairs, structural work, or electrical and plumbing restoration after a flood. Check with your local building department to determine permit requirements and associated fees for your flooded basement cleanup project. Obtaining the correct permits helps ensure work is done safely and up to code.

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.
