Our Services

Foundation and crawlspace protection tailored to Gresham homes.

Foundation Waterproofing

Gresham's consistent winter rainfall and high water table create constant pressure on basement walls. We seal exterior and interior foundation surfaces to stop seepage before it becomes structural damage.

Older homes in neighborhoods like Rockwood often lack modern waterproofing. We use proven epoxy and polyurethane sealants on concrete cracks and joints to keep water out for decades.

Crawlspace Vapor Barrier Installation

Unsealed crawlspaces absorb moisture from Gresham's clay-rich soil, creating damp conditions that fuel mold and rot. We install 6-mil or thicker vapor barriers to isolate your crawlspace from soil moisture.

Especially critical in Pleasant Valley and Kelly Creek where homes sit in low-lying areas. A properly sealed crawlspace keeps humidity under control and protects wood framing.

Crawlspace Cleanup & Encapsulation

Many older Gresham homes have crawlspaces filled with debris, damaged insulation, or standing water. We remove contaminated materials and encapsulate the space to create a clean, dry environment.

This protects both the structural integrity of your home and the air quality inside. North Gresham homes near Butler Creek benefit especially—water runoff during storms can flood crawlspaces quickly.

Window Well Covers & Waterproofing

Basement window wells are water traps in Gresham's wet climate. We install custom-fit metal or plastic covers with drainage systems to keep rain and debris out while allowing light in.

Window well covers are often overlooked but save thousands in water damage claims. Homes in Central City and Centennial benefit greatly from this simple, effective upgrade.

Why Local Waterproofing Matters in Gresham

Water damage is one of the fastest-growing insurance claims in Oregon—and Gresham's climate makes your home vulnerable.

Winter rains are relentless. An unprotected foundation invites moisture into your home, where it spreads to wood framing, electrical systems, and personal property. Even 'small' water damage can escalate into major repairs within 48 hours.

Waterproofing isn't cosmetic—it's structural protection. When we seal a foundation or install a vapor barrier, we're preventing foundation settling, mold growth, and the loss of your home's resale value. Gresham homebuyers expect dry basements and crawlspaces.

Why Gresham Needs Waterproofing Contractors

Three factors make waterproofing urgent in Gresham: heavy winter rainfall, clay-heavy soils that trap moisture, and an aging housing stock. Many homes built in the 1970s and 1980s lacked the waterproofing standards of today.

Neighborhoods like Rockwood, Kelly Creek, and Centennial have large populations of older homes. Combined with the region's high water table and frequent storms, water intrusion is common—and preventable with professional waterproofing.

We start before the problem becomes an emergency.

Waterproofing Across Gresham Neighborhoods

Each neighborhood faces unique water challenges.

Rockwood & North Gresham

Older housing stock with limited original waterproofing. High water table and proximity to Butler Creek mean water pressure builds fast. Foundation sealing and crawlspace encapsulation are priority services here.

Pleasant Valley & Kelly Creek

Low-lying topography with dense clay soils. Lot grading often directs water toward foundations. We focus on drainage solutions, vapor barriers, and exterior sump pump systems.

Central City & Centennial

Downtown and nearby neighborhoods with older single-family homes and apartment buildings. Window well covers, basement waterproofing, and crawlspace upgrades are common services.

Frequently Asked Questions

How do I know if my Gresham home needs waterproofing?

Signs include wet spots on basement walls, a musty odor, efflorescence (white powder on concrete), water staining, or visible cracks in the foundation. Homes built before 1990 in Rockwood, Kelly Creek, and other older neighborhoods benefit from professional assessment. Even if you don't see standing water, seepage or dampness indicates a waterproofing need.

What's the best time to waterproof a foundation in Gresham?

Spring and early summer are ideal because they allow us to work before fall and winter rains return. Interior waterproofing can be done year-round, but exterior work is easier when the ground is dry. Contact us in spring or early summer to schedule before the busy season.

How long does waterproofing last?

Quality waterproofing sealants last 10–20 years depending on soil conditions and maintenance. Vapor barriers typically last 15–25 years. We recommend inspections every 3–5 years to catch any deterioration early. Gresham's wet climate does age materials faster, so regular check-ups protect your investment.

Can I waterproof just part of my foundation?

Yes. If water enters from one wall or corner, we can target that area first. However, because Gresham's water table and clay soils create uniform pressure, we often recommend full-perimeter protection for lasting results. We'll discuss your priorities during the inspection.

Do I need interior or exterior waterproofing?

Both approaches work. Exterior waterproofing prevents water from reaching the foundation; interior systems manage water that enters. For older Gresham homes with limited exterior access, interior membranes or sump systems are effective. We recommend the right approach after inspecting your home.
