No hourly guessing games — pricing is based on what the diagnostic actually finds at your property.

Real Diagnostic Equipment On Every Truck

We map your full basement perimeter before recommending anything — staining alone doesn't tell the whole story.

Our Basement Waterproofing Service Lineup

We don't run a one-size-fits-all playbook — every basement waterproofing job starts from these core service components, adapted to what your property actually needs.

Perimeter Drain Tile & Sump Basin Installation

Coring runs the full interior perimeter, with drain tile bedded in washed gravel and tied into a sealed basin sized to your water table. The basin gets a cast-iron or high-torque pump with battery backup as standard, since power loss during a storm is exactly when you need it running.

Hydrostatic Pressure Relief

Groundwater pressure that builds faster than a wall can shed it finds the weakest point — a cove joint, a tie-rod hole, a hairline crack. Left alone, this kind of pressure doesn't just cause seepage — it can bow a block wall over years.

Wall & Floor Crack Injection

Cracks under an eighth of an inch and stable are strong candidates for polyurethane injection, which fills the crack's full depth and stays flexible with seasonal movement. Every crack is photographed and logged before and after treatment.

Battery Backup Pump & Alarm Systems

A primary pump that fails silently is the single most common cause of preventable flooding we see on service calls. Cellular notification add-ons put the alert on your phone, not just a beeping alarm in an empty house.

Interior Wall Vapor Barrier

Dimple-board membrane creates an air gap against the foundation wall, directing incidental moisture down to the drain tile rather than into insulation and drywall.
