Our Basement Waterproofing Process

01

Water Source Diagnosis

We determine whether water is entering through the floor, wall cracks, cove joint, or window wells — each requires a different approach.

02

Solution Design

A comprehensive waterproofing plan is developed — interior drainage, exterior excavation, crack injection, or a combination.

03

Installation

For interior drainage: perimeter drain tile is installed, sump pit is excavated, and a sump pump is installed. Crack injection fills structural cracks from the inside.

04

Grading & Drainage

Exterior drainage improvements — grading, downspout extensions, window well drains — are addressed to reduce water pressure against the foundation.

Basement Waterproofing FAQ for Fresno Homeowners

How often should Fresno homeowners get basement waterproofing?
Given Fresno's extreme summer heat averaging 99°f in july — 110°f+ days are not uncommon, most homeowners benefit from basement waterproofing at least once a year. Summer UV bleaching and cracking of stucco, paint, and caulk often makes spring or fall the optimal time to schedule service.
What home types in Fresno most need basement waterproofing?
Stucco ranch homes from 1960s–1990s throughout Fresno County and New construction in Clovis and northwest Fresno are the most common home types in Fresno and typically see the most wear. Our local pros are familiar with the exterior materials found across the metro.
What causes a basement to leak?
The most common causes: hydrostatic pressure from saturated soil, cracks in the foundation wall or floor, failed parging or waterproofing membrane, poor grading directing water toward the home, and clogged or inadequate drainage.
Interior vs. exterior waterproofing — which is better?
Exterior is the ideal solution but requires excavating around the entire foundation — expensive and disruptive. Interior drainage systems manage water that gets in and are more practical for most existing homes. The right answer depends on the specific water entry point.
How much does basement waterproofing cost?
Interior drainage systems run $5,000–$15,000. Exterior waterproofing with excavation is $20,000–$50,000+. Crack injection for single cracks runs $500–$3,000.
Will waterproofing allow me to finish my basement?
Yes. A properly waterproofed basement with humidity control is safe to finish with framing, insulation, and drywall. An active water problem must be fully resolved before finishing.
