We had a major basement flooding issue, and no one could figure it out—until we called Aquamaster Waterproofing. Sarah and David were thorough during the inspection and found that our sump pump had failed. They replaced it, installed a backup pump, and added better drainage around the foundation. The system works flawlessly now, and our basement has been dry ever since. Five-star service from a truly reliable company.

They installed a sump pump, sealed all visible cracks, and made sure our drainage system was working correctly. The workers were polite, neat, and extremely knowledgeable. It’s rare to find a company that combines great service with such high-quality workmanship. I’m beyond satisfied with the results.
