A wet basement almost always starts outside. We excavate to the footing, clean and seal the foundation wall, install drain board and a new footing drain, then correct the grading, window wells, and downspouts so water leaves the property instead of collecting against it.
The crew that inspects it installs it. One point of contact from the first basement walk to the final test.
A specific number for your basement, in writing, that does not move after the inspection.
Installed to last and stood behind. 5 stars on Google says the work holds up.
Tell us where the water shows up, the address, and how long it has been happening. We will inspect it and put a fixed number in writing, for free.
