Below-Grade and Basement Wall Waterproofing in South Portland
Older farmhouses and capes often have a mix 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.
Foundation Crack Repair & Sealing in South Portland
Even minor cracks in foundation walls can allow serious water intrusion. Our services include crack repair using epoxy or polyurethane injection to seal these entry points for good. This method fills the entire depth of the crack, restoring strength and preventing water penetration. We address both vertical and horizontal cracks, knowing that horizontal cracks can signal structural issues that need a thorough assessment before sealing. Addressing these early prevents further water damage and expensive future repairs.
Plumbing Leak Behind Walls in South Portland
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 walls.
Exterior Foundation Waterproofing in South Portland
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. Basements are standard in most Maine homes, and groundwater and snowmelt make sump pumps and drainage important. Proper drainage solutions, such as French drains, are also added to divert water away.
Basement Wall Sealing in South Portland, ME
Basement wall sealing is a critical part of walls waterproofing. Maine has a long, cold heating season, so boilers, water heaters, and heating pipes work hard for many months. 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 South Portland, ME basement.
Laundry Room and Utility Wall Waterproofing in South Portland, 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.
Commercial Walls Waterproofing in South Portland
Beyond residential properties, BKN Plumbing also offers walls waterproofing services for commercial buildings in South Portland. Protecting commercial basements, equipment rooms, and underground parking garages from water damage is essential to business operations. We understand the need for minimal disruption and efficient project completion for commercial clients. Our team works with property managers and business owners to install robust waterproofing solutions that fit the demands of commercial structures and their code requirements.
Sump Pump Installation and Repair in South Portland, ME
Sump pumps are a key part of many interior waterproofing systems, particularly in homes that see heavy rainfall. We install high-capacity sump pumps designed to handle large volumes of water, keeping your basement dry even during flash floods. Our services include primary sump pump installation, battery backup sump pump systems for power outages, and routine maintenance or repair of existing units. We make sure the discharge line is routed correctly so water does not circulate back toward the foundation.

Frequently Asked Questions About Walls Waterproofing in South Portland
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.
BKN Plumbing works with reputable 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 site.
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.
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.
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 friendly to mold and mildew growth, improving air quality and protecting your belongings from moisture damage.
Walls waterproofing is a primary step in preventing future mold growth by eliminating the moisture source. However, it does not remove existing mold. If mold is already present, it will need to be professionally remediated before or along with the waterproofing process. Once the area is dry and mold-free, waterproofing will help make sure it stays that way.
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 specifically engineered 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.
