Drainage System Integration in Kennebunk, ME
Lasting walls waterproofing often requires a robust 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 Kennebunk, ME properties, so water is efficiently managed and moved away from your home's vulnerable areas.

Below-Grade and Basement Wall Waterproofing in Kennebunk
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 builds up.
Basement Wall Sealing in Kennebunk, ME
Basement wall sealing is a key part of walls waterproofing. Maine has a long, cold heating season, so boilers, water heaters, and heating pipes work hard for much of the year. 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 Kennebunk, ME basement.
Crawl Space Encapsulation in Kennebunk
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, preventing mold growth and wood rot in the crawl space. Maine has a long, cold heating season, so boilers, water heaters, and heating pipes work hard for many months. An encapsulated crawl space can significantly improve indoor air quality and energy efficiency by keeping moisture from moving up into the home. We use tough, reinforced poly sheeting for walls and floors, sealed at all seams and penetrations.
Exterior Foundation Waterproofing in Kennebunk
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. Much of Maine has rocky glacial soil and shallow ledge, which can make digging for sewer, water, and septic lines difficult. Proper drainage solutions, such as French drains, are also added to divert water away.
Shower Wall Waterproofing in Kennebunk
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 reinforcement before new tile is set.
Waterproofing Costs vs. Repeat Water Damage in Kennebunk, ME
Waterproofing a shower or wall costs far less than repeated drywall, cabinet and flooring repairs. Ignoring moisture also invites mold, which can be expensive to remediate. A typical shower wall waterproofing project falls in the low thousands, while exterior block sealing varies with wall size. We give you a written quote so you can compare options side by side.

Laundry Room and Utility Wall Waterproofing in Kennebunk, ME
Washing machine hoses, utility sinks and water heaters can all leak into nearby walls. We replace burst-prone rubber hoses with braided stainless hoses and install leak pans and shutoff valves. Walls around water heaters and laundry boxes can be sealed to resist water damage. These small upgrades head off costly drywall repairs.

Frequently Asked Questions About Walls Waterproofing in Kennebunk
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 usually ranges from $2,500 to $8,000.
BKN Plumbing works with trusted manufacturers known for high-quality waterproofing products. We commonly use products from brands like Xypex, Tremco, and Sika for their proven effectiveness and durability, from crystalline admixtures to elastomeric membranes and sealants. We select the best product for your foundation type and conditions.
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.
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 heavier growth.
For extensive walls waterproofing projects that involve excavation, major structural changes, or changes to drainage systems, a permit from the Kennebunk 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.
Look for signs such as damp or wet spots on basement or crawl space walls, a musty odor, visible mold or mildew growth, efflorescence, a white powdery residue, on concrete or brick, and standing water. Cracks in foundation walls or bowing walls also indicate potential water entry issues. If you notice any of these, it's wise to get a professional assessment.
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 trusted names known for their durability and effectiveness in preventing water penetration.
The duration of a walls waterproofing project varies depending on its scope. Minor crack repairs might take a few hours, while an interior drainage system could take 1 to 3 days. A full exterior foundation waterproofing project, involving excavation around the entire home, could take 3 to 7 days or more. We provide a clear timeline during our first consultation.
