Foundation Crack Repair in Lewiston
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 promptly in Lewiston homes is crucial to avoid larger, more costly structural issues.

Interior Walls Waterproofing in Lewiston, ME
Interior walls waterproofing focuses on managing water that has already penetrated the foundation walls. This typically involves installing an interior drainage system, often called a French drain, along the perimeter of the basement floor. Water is collected and channeled to a sump pump, which then sends it safely away from the foundation. While not preventing water from entering the wall, it stops it from pooling inside your living space. This solution is less disruptive than exterior excavation and is suitable where exterior access is limited.
Plumbing Leak Behind Walls in Lewiston
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.
Laundry Room and Utility Wall Waterproofing in Lewiston, 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.
Exterior Block Wall Waterproofing in Lewiston, 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 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.
Shower Pan Leak Repair and Waterproofing in Lewiston, 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 verify 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 confirms the pan is watertight before tile.
Exterior Foundation Waterproofing in Lewiston
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 integrated to divert water away.

Frequently Asked Questions About Walls Waterproofing in Lewiston
Shower wall waterproofing with a membrane system typically 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.
Yes. Sealing a wall with an active leak behind it traps water and causes more damage. We always fix the leak and dry the cavity first.
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.
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.
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.
Yes. Our workmanship is warrantied, and many membrane systems carry their own manufacturer warranty when installed correctly. We explain the coverage in your written estimate.
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.
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.
