Waterproofing for Older Homes in Ontario, CA

Older homes, especially those built before modern waterproofing standards, are particularly prone to water intrusion. Copper pinhole leaks and corroded cast iron drains are frequent repair calls in homes that are now several decades old. Many older foundations may lack adequate exterior drainage or proper sealing. We specialize in assessing and upgrading waterproofing systems for these properties, often combining exterior excavation with interior drainage solutions. We take care to respect the existing structure while installing modern, effective waterproofing, with attention to the challenges of older brick and stone foundations.

Exterior Foundation Waterproofing in Ontario

Exterior foundation waterproofing involves excavating around the foundation to apply a waterproof membrane or coating directly to the wall. This is often the most effective method for preventing water from entering the basement or crawl space. We use high-quality asphalt-modified polyurethane membranes or polymer-based coatings that resist hydrostatic pressure and soil movement. Most homes in Southern California sit on concrete slabs, so slab leaks often show up as warm floors, wet carpet, or an unexplained jump in the water bill. Proper drainage solutions, such as French drains, are also added to divert water away.

Below-Grade and Basement Wall Waterproofing in Ontario

Copper pinhole leaks and corroded cast iron drains are common repair calls in homes that are now several decades old. Wherever a home has a basement or below-grade walls, heavy rain and snowmelt can push water through foundation walls and cracks. We seal cracks with injection products, apply interior or exterior waterproofing and install drainage where needed. A sump pump may be added if groundwater collects.

Shower Pan Leak Repair and Waterproofing in Ontario, CA

A cracked or poorly sloped shower pan often causes wet baseboards and stained ceilings below. We test the pan by plugging the drain and flooding it to verify the leak. Then we rebuild the pan with correct pre-slope, a new liner or bonded membrane and a properly clamped drain. A second flood test proves the pan is watertight before tile.

Sump Pump Installation and Repair in Ontario, CA

Sump pumps are a critical part of many interior waterproofing systems, particularly in homes that see heavy rainfall. We install high-capacity sump pumps designed to handle large volumes of water, keeping your basement dry even during heavy storms. Our services include primary sump pump installation, battery backup sump pump systems for power outages, and routine maintenance or repair of existing units. We make sure the discharge line is routed properly so water does not circulate back toward the foundation.

Crawl Space Encapsulation in Ontario

Crawl space encapsulation involves sealing the crawl space entirely with heavy-duty vapor barriers and often includes a dehumidifier. This not only waterproofs the walls but also controls humidity, stopping mold growth and wood rot in the crawl space. Hot inland summers push water heaters and outdoor plumbing hard, while coastal salt air can corrode exposed metal fittings. An encapsulated crawl space can noticeably improve indoor air quality and energy efficiency by keeping moisture from moving up into the home. We use durable, reinforced poly sheeting for walls and floors, sealed at all seams and penetrations.

Foundation Crack Repair in Ontario

Even small cracks in your foundation walls can allow water to seep into your basement or crawl space. Our walls waterproofing service includes foundation crack repair using specialized epoxy or polyurethane injection techniques. These materials fill and seal cracks, preventing future water entry and often strengthening the foundation. Addressing cracks early in Ontario homes is important to avoid larger, more costly structural issues.
