Waterproofing for Older Homes in Gresham, OR
Older homes, especially those built before modern waterproofing standards, are particularly prone to water intrusion. Homes built from the late 1970s into the mid 1990s may still have polybutylene pipe, which is prone to unexpected failures. 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 respect the existing structure while installing modern, effective waterproofing, with attention to the challenges of older brick and stone foundations.

Exterior Block Wall Waterproofing in Gresham, OR
Block and stem walls often show efflorescence, which is the white mineral crust left when water passes through masonry. Irrigation and sprinklers aimed at the house are frequent culprits. We adjust or reroute irrigation, clean the wall and apply a breathable masonry sealer or elastomeric coating. Proper grading and drip line placement help keep the wall dry.
Drainage System Integration in Gresham, OR
Lasting walls waterproofing often requires a solid drainage system to divert water away from your foundation. This can include interior perimeter drains that channel water to a sump pump, or exterior French drains that collect surface water. Our team designs and installs custom drainage solutions for Gresham, OR properties, so water is managed well and moved away from your home's vulnerable areas.
Plumbing Leak Behind Walls in Gresham
A slow drip from a shower valve, supply stub or drain fitting can soak a wall for months before you notice. We find the leak with moisture meters, thermal imaging and pressure tests. The damaged section of pipe or valve is replaced, and wet drywall is cut out and dried. Once the cavity is dry, we restore the wall and seal any wet-area surfaces.
Below-Grade and Basement Wall Waterproofing in Gresham
Homes built from the late 1970s into the mid 1990s may still have polybutylene pipe, which is known for unexpected failures. 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 builds up.

Frequently Asked Questions About Walls Waterproofing in Gresham
The cost of walls waterproofing in Gresham, OR can vary a great deal based on the method used, the extent of the damage, and the size of your foundation. Basic crack sealing might range from $300 to $800 per crack, while a full exterior foundation waterproofing project could be $8,000 to $20,000 or more. Interior drainage systems with a sump pump usually fall between $4,000 and $12,000. We provide transparent, itemized quotes after a thorough inspection.
Yes. Our workmanship is warrantied, and many membrane systems carry their own manufacturer warranty when installed correctly. We explain the coverage in your written quote.
Key signs you need walls waterproofing include damp or wet basement walls, visible mold or mildew growth, a musty odor in your basement or crawl space, efflorescence on concrete walls, cracks in the foundation, or standing water after heavy rains. Don't ignore these warning signs, as they often point to ongoing water intrusion.
For extensive walls waterproofing projects that involve excavation, major structural changes, or changes to drainage systems, a permit from the Gresham building department may be required. We will advise you on any necessary permits and help with the application process so all work complies with local codes.
Interior waterproofing addresses water after it has entered the foundation, usually managing it with sealants and drainage systems inside the basement or crawl space. Exterior waterproofing prevents water from reaching the foundation walls in the first place, usually by excavating and applying membranes or coatings to the outside of the foundation.
For extensive walls waterproofing projects involving excavation, structural changes, or major changes to drainage systems, a permit from the city of Gresham may be required. Simple crack repairs typically do not need a permit. JFL Plumbing will help you determine if a permit is necessary for your project and handle the application process if needed.
Damp proofing is a less robust solution, typically a spray-on asphalt coating that resists soil moisture but isn't designed to withstand hydrostatic pressure. Waterproofing uses stronger membranes, coatings, or drainage systems built to prevent liquid water from entering, even under pressure. For basements or crawl spaces in areas with high water tables or heavy rainfall, waterproofing is the right choice.
Waterproofing prevents the moisture mold needs to grow. Existing mold should be removed and the area dried before sealing. We remove affected materials when needed and recommend remediation for larger growth.
