Shower Pan Leak Repair and Waterproofing in Ketchikan, AK
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 confirms the pan is watertight before tile.

Crawl Space Encapsulation in Ketchikan
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, stopping mold growth and wood rot in the crawl space. A long, severe heating season is the defining plumbing stress in Alaska, and boilers and water heaters run hard for much of the year. 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.
Plumbing Leak Behind Walls in Ketchikan
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 walls.
Shower Wall Waterproofing in Ketchikan
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.
Interior Walls Waterproofing in Ketchikan, AK
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.
Foundation Crack Repair in Ketchikan
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 Ketchikan homes is important to avoid larger, more costly structural issues.
Drainage System Integration in Ketchikan, AK
Effective 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 Ketchikan, AK properties, so water is efficiently managed and moved away from your home's vulnerable areas.

Commercial Wall Waterproofing in Ketchikan
Restaurants, gyms, salons and offices often have restrooms, locker rooms and kitchens with constant water exposure.

We also repair the plumbing behind those walls when leaks are found.

Frequently Asked Questions About Walls Waterproofing in Ketchikan
The cost of walls waterproofing in Ketchikan, AK can vary a lot, typically ranging from $3,000 for interior crack sealing to $15,000 or more for extensive exterior foundation waterproofing with drainage systems. Factors like the size of the area, severity of water damage, chosen methods, and accessibility all affect the final price. We provide detailed, transparent quotes after a thorough inspection.
CKN 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 conditions.
Damp proofing is a less durable 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.
For extensive walls waterproofing projects involving excavation, structural changes, or major changes to drainage systems, a permit from the city of Ketchikan may be required. Simple crack repairs typically do not need a permit. CKN Plumbing will help you determine if a permit is necessary for your project and assist with the application process if needed.
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.
A shower wall waterproofing project usually takes two to four days, including drying time between coats. Exterior block sealing can often be completed in a day. Larger foundation jobs may take several days.
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 inspection.
When professionally installed using high-quality materials, walls waterproofing can last for many 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 lasting durability.
