Our skilled technicians are equipped with the latest tools and technologies to resolve any damp basement situation—from advanced sump pumps to interior drainage and beyond. Let us find the right solution for your basement’s unique needs!

Control Basement Wall Moisture

What We Do

Excessive moisture can wreak havoc on your basement by enabling mold growth. It also ruins materials stored in the space, such as fabric and wood, and damages your belongings. Moisture doesn’t just enter basements through open windows and doors—it can also seep in via small cracks in the walls. That’s why we recommend sealing your basement walls with an industry-leading vapor barrier as the first crucial step in waterproofing.

What We Use

WallSeal™ Basement Wall Vapor Barrier

Control Ground Water Seepage

What We Do

You can’t keep all water out of your basement entirely. Doing so could actually increase pressure on your home from the outside. Instead, you want to control the amount of water that accumulates in your basement and ensure it doesn’t damage your property. Our interior and drainage sump pump systems can effectively collect and remove any unwanted water from your basement.

What We Use

Sump Pump System

Interior Drain System


Manage Humidity and Improve Air Quality

What We Do

An energy-efficient dehumidifier is the final component of our comprehensive basement waterproofing solution. It removes mold spores from the air that can impact your property’s foundations and your family’s health. A high-quality dehumidifier cleans the air and reduces moisture levels.
