What We Install
We match the waterproofing system to the source of the water, then install the drainage, sealing, pumping, and moisture-control layers your basement needs to stay dry.
Interior Drainage System
Perimeter drainage channels installed along the basement floor intercept water before it pools. Gravity-fed or connected to a sump system.
Interior.Stops pooling.
Exterior Waterproofing
Membrane coating and drainage board on exterior foundation walls stops water at the source before it contacts the structure.
Exterior.Source control.
Sump Pump Systems
Battery backup sump systems actively remove water 24/7. We install, maintain, and warrant the entire system.

Humidity & Moisture Control

The Attic Pro team was amazing! Mynor Hernandez was fantastic! He kept me up to date on status and timeline. When complete, he shared photos of his team's excellent workmanship.
The workers arrived on time were professional and explained everything they were doing very well. Work proceeded in an expeditious manner, and everything was very well done. And the cleanup was excellent.
I bought an older house that hadn’t been maintained for years. There were a lot of entry points for rats to enter the attic, crawl space, and garage. I needed work on the HVAC, asbestos in the crawl space, insulation in the attic, as well as rat exclusion. The issue had gotten out of control and they were able to help at a much more affordable rate than all the other estimates I’d received. ...
Jose Olguin did an outstanding job finishing and inspecting work done on my house so professional loved him coming out and making sure everything was done properly .Attic Pro's great company.
