San Leandro, California homeowner Nathan faced years of winter woes: flooded basements, moldy crawl spaces, and constant worry. This spring's deluge pushed him to seek a permanent solution.

 

He contacted Clean CrawlSpace for a permanent solution. Our expert moisture control specialist Daniel Griggs identified the source of moisture in Nathan’s crawlspace. Then our skilled installation crew came, installed a sump pump to permanently combat water infiltration, and sealed her crawl space using the innovative CleanSpace® Crawl Space Vapor Barrier system, installing a sump pump system with water trenches. The trenches collect rainwater before it can seep in, while the pump whisks it away from the house. 

 

The result? A bone-dry crawl space, a worry-free basement, and peace of mind for Nathan. If you're a San Leandro homeowner battling water woes, ditch the flood fears and call Clean CrawlSpace today. Their sump pump system might just be the lullaby your rainy season needs.

Job Stories From San Leandro, CA
Sump Pump System Saves San Leandro, CA Home

Nathan used to dread the heavy storms in San Leandro, CA. His crawlspace would turn into a soggy mess, leaving him worried about flooding and mold. This past spring, the nightmare was worse than ever. Water seeped into his basement, damaging flooring and creating a musty nightmare. Enough was enough! That's when he called Clean CrawlSpace. 

 

 

Our expert moisture control specialist Daniel Griggs identified the source of moisture in Nathans crawlspace. Then our skilled installation crew arrived and installed a sump pump. (A sump pump is a small pump that is installed in a pit in the basement or crawlspace. When the water level in the pit rises, the sump pump will turn on and pump the water out of the pit. This can help to prevent water from entering your home through the foundation.) The installation was quick and professional. 

 

Now, Nathan’s crawl space stays dry and healthy, thanks to Clean CrawlSpace. If you're facing water woes in San Leandro, CA, don't wait – call Clean CrawlSpace and ditch the worries!

I am interested in getting my crawl space encapsulated with a moisture/vapor barrier. The crawl space is more like a basement where you can actually walk underneath the house because its graded on a hill.
