"They called as soon as I searched for a pro and coincidentally, they’re the same pro our friends referred to us as they also got their plumbing services when they bought a home. We didn’t have to wait for a week or so, they made it possible to have the job completed before we left (we were just visiting from Vegas to help our son moved to his new home). Everything went flawless, Trey went above and beyond. He noted other issues that need to be taken care of and he finished it in a timely manner, no hiccups thank God."

"overall good. All these guys worked very hard to get it done. When hiring a waterproofing company to waterproof a basement I would expect the company to fix any water issues coming into the basement that was uncovered during the process. When we tore sheetrock off the basement wall in one corner we seen a water issue letting water to come in to the bedroom. One guy told us that it was above his pay grade. We had to go thru 2 different handymen before we got it resolved. Again you all advertise waterproofing basements with a lifetime warranty. Other than that your people worked hard to complete our job so please let them know. Thanks."

Basement Waterproofing FAQs, answered by experts

Yes. Water can penetrate through a concrete foundation wall. This can happen whether or not you have cracks, as concrete is a porous material. You’ll want to take steps to waterproof your basement or crawl space.

Several factors can impact the cost of waterproofing your basement. Some of the most common cost factors include:

  • Location

  • Square footage

  • Cause of the water leak

  • Type of foundation

  • Accessibility

  • Waterproofing method

  • Materials

  • Contractor experience and availability

  • Engineering reports, if needed

  • Structural and other repairs

  • Permits

Plan on cleaning your crawl space at least once a year, though twice a year is ideal. During the cleaning, remove any debris or dust and check for potential issues like pest infestations or water damage. The sooner you catch these issues, the easier (and cheaper) it will be to fix them.

Installing a bathroom in a basement isn’t a project for most homeowners. Many parts—plumbing, electricity, and carpentry—go into this project, each requiring expert-level knowledge and tools. One miscalculation can lead to very expensive repairs. Plus, some homeowner’s insurance might not pay for damages caused by a homeowner DIYing this project. You can protect yourself by allowing the pros to complete this job for you. 

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.
