Waterproofing for Older Homes in Tacoma, WA
Older homes, especially those built before modern waterproofing standards, are particularly prone to water intrusion. Newer homes in Tacoma usually use PEX supply lines, and many older houses have been partially repiped over the years. 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 Tacoma, WA
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 common 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.
Plumbing Leak Behind Walls in Tacoma
A slow drip from a shower valve, supply stub or drain fitting can soak a wall for months before you notice. We locate 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.
Basement Wall Sealing in Tacoma, WA
Basement wall sealing is a key part of walls waterproofing. East side homes near Tacoma and beyond face bigger temperature swings, which strain pipes, fittings and outdoor plumbing. We apply high-quality sealants to porous concrete and masonry walls to prevent moisture from wicking through and causing dampness, mold, or musty odors. This service can be performed alone or as part of a larger waterproofing system, offering a drier and healthier environment in your Tacoma, WA basement.
Below-Grade and Basement Wall Waterproofing in Tacoma
Newer homes in Tacoma usually use PEX supply lines, and many older houses have been partially repiped over the years. 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.
Foundation Crack Repair in Tacoma
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 proven epoxy or polyurethane injection techniques. These materials fill and seal cracks, preventing future water entry and often strengthening the foundation. Addressing cracks early in Tacoma homes is important to avoid larger, more costly structural issues.

Frequently Asked Questions About Walls Waterproofing in Tacoma
Shower wall waterproofing with a membrane system usually runs $1,200 to $3,500 including demolition and backer board, not counting new tile. Exterior block wall sealing often costs $800 to $3,000 depending on size. Below-grade foundation waterproofing generally ranges from $2,500 to $8,000.
Yes, FHN Plumbing stands behind the quality of our walls waterproofing services. We offer full warranties on our materials and workmanship, giving you peace of mind. Warranty details will be provided with your project proposal, outlining the coverage and duration of your waterproofing system.
Walls waterproofing is generally not recommended as a DIY project due to its complexity and the high importance of a sound foundation. It often involves heavy excavation, specialized equipment, precise material application, and knowledge of drainage principles and local building codes. Improper waterproofing can lead to more severe and costly damage down the line, so professional help is highly advisable.
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.
Absolutely. By preventing water intrusion through your walls, waterproofing significantly reduces the moisture and humidity levels in your basement or crawl space. This creates an environment less conducive to mold and mildew growth, improving air quality and protecting your belongings from moisture damage.
Shower remodels that change plumbing or drain locations often require a permit. Simple membrane replacement may not. We check local requirements and pull permits when needed.
Interior waterproofing addresses water after it has entered the foundation, typically 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.
Skilled DIYers can roll on liquid membranes, but mistakes at seams, corners and drains often lead to leaks. Shower pans also require correct slope and flood testing. Professional installation lowers the risk of hidden water damage.
