"I contracted with American Foundation & Basement Repairs, LLC for waterproofing services to include replacing the drywall once the installation was complete. The salesman listened to me, made all the changes that I requested, answered my questions, and did it all quickly, efficiently, and without pressure. The work crews were courteous, cleaned up after themselves, hauled away all the debris, and kept me well informed throughout the process. They called daily to let me know when they would arrive since the repair was not at my residence, giving me plenty of time to get there to let them in the house."

"Blalock waterproofing did a fantastic job in my basement. Cory came out, gave an estimate and completed the job of 60 ft of waterproofing in just 6 days. From estimate to completion in 6 days, amazing. He started on Monday and Wed. Afternoon, cleaned up and job down. He dealt with my stairs- they were in the way, and added some additional support to the 4x4s that had been rotted out from all the water at floor level. Final price was exactly what was estimated. Hire them!"

Basement Waterproofing FAQs, answered by experts

The process might take a few days to a week, depending on the method chosen, area size, and weather conditions. Some solutions, like simple interior sealants, may require less time.

Water damage to concrete is often gradual and can take months, if not years, for a concrete structure to be fully destroyed. The process often starts with cracks on the surface, followed by sinking slabs and eventually crumbling cement. Therefore, it is important to repair minor damages early to prevent the situation from worsening.

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

Underfloor insulation alone will not cause moisture and mold, but improper installation can. Although the purpose is to seal any drafts, your subfloor still needs ventilation. If you seal the area too tightly and prevent all airflow, this can cause moisture to get trapped. This moisture eventually leads to mold and—if your floors are wood—rotting.

Roughing in and connecting utilities are the hardest parts of finishing a basement, and they’re the parts we typically don’t recommend doing as a DIY project. Unfortunately, your finishing timeline can be extended by weeks while you wait for contractors and inspectors to install electrical wiring, plumbing lines, and heating/cooling equipment and carry out inspections.
