Interior Waterproofing

Interior waterproofing keeps moisture, musty smells, and staining out of your living space by sealing your basement from the inside. It's a clean, less-invasive option that's ideal for damp walls, minor seepage, and protecting a finished basement.

We seal your foundation walls and the wall–floor joint where water most often sneaks in, add a vapor barrier, and pair it with a sump pump for any water that does get through. The result is a drier, brighter, healthier basement.
