Waterproofing for Older Homes in Bangor, ME
Older homes, especially those built before modern waterproofing standards, are particularly prone to water intrusion. Older farmhouses and capes often have a patchwork of copper, galvanized, and plastic plumbing from many decades of repairs. 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.

Shower Pan Leak Repair and Waterproofing in Bangor, ME
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 confirm 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.
Commercial Wall Waterproofing in Bangor
Restaurants, gyms, salons and offices often have restrooms, locker rooms and kitchens with constant water exposure. We waterproof commercial showers, mop sink walls and restroom wet walls with durable membranes. Work can be scheduled after hours to limit downtime. We also repair the plumbing behind those walls when leaks are found.
Crawl Space Vapor Barriers in Bangor
Many homes in Bangor have crawl spaces, which are highly susceptible to moisture issues. Installing a heavy-duty vapor barrier on crawl space walls and floors is a key waterproofing strategy. This thick polyethylene sheeting prevents ground moisture from evaporating into the crawl space, protecting subflooring and joists and improving indoor air quality. It's an affordable way to control humidity and prevent wood rot.
Shower Wall Waterproofing in Bangor
Tile and grout are not waterproof on their own, so water reaches the backer board in every shower. If the walls were built without a proper membrane, moisture soaks into studs and drywall. We remove failing tile, install cement board or foam board and apply a membrane such as Schluter Kerdi, RedGard or Hydro Ban. Seams, corners and niches get extra attention before new tile is set.
Exterior Block Wall Waterproofing in Bangor, ME
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.

Below-Grade and Basement Wall Waterproofing in Bangor
Older farmhouses and capes often have a patchwork of copper, galvanized, and plastic plumbing from many decades of repairs. 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.

Frequently Asked Questions About Walls Waterproofing in Bangor
The cost of walls waterproofing in Bangor, ME can vary significantly 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 clear, itemized quotes after a thorough inspection.
Sprinklers and drip lines aimed at the house are the most common cause. Heavy storms and poor grading also send water toward walls. Masonry absorbs that water and leaves mineral deposits as it dries out.
When professionally installed using high-quality materials, walls waterproofing can last for decades, often 20 to 50 years or even longer. The lifespan depends on the materials used, the quality of installation, and environmental factors like soil movement and water exposure. Modern membranes and sealants are designed for long-term durability.
The duration of a walls waterproofing project varies significantly. Smaller jobs like interior crack sealing might take a day or two, while extensive exterior waterproofing with excavation and drainage system installation could take several days to over a week. We'll provide a clear timeline during your consultation.
Walls waterproofing is generally not recommended as a DIY project due to its complexity and the critical 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 the smart choice.
We use a range of high-performance waterproofing membranes and coatings depending on the application and foundation type. These can include liquid asphalt-modified polyurethane, rubberized asphalt membranes, bentonite clay systems, and crystalline coatings. Brands often include well-known names known for their durability and effectiveness in preventing water penetration.
Shower remodels that change plumbing or drain locations often require a permit. Simple membrane replacement may not. We check local requirements and obtain permits when needed.
While minor DIY fixes like patching small cracks are possible, full walls waterproofing is best left to professionals. It involves specialized knowledge of drainage, foundation mechanics, and proper material application. Improper DIY work can lead to ineffective results, wasted money, and worse water damage over time.
