Crawl Space Encapsulation in New Bedford
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. Humid summers bring condensation on cold water lines and musty basements, which can hide slow leaks until damage appears. An encapsulated crawl space can noticeably 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.

Waterproofing for Older Homes in New Bedford, MA
Older homes, especially those built before modern waterproofing standards, are especially prone to water intrusion. Cast iron drains, galvanized supply lines and old lead service connections are still found in multi-family houses and older single-family homes. 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 take care to respect the existing structure while installing modern, effective waterproofing, with attention to the challenges of older brick and stone foundations.
Exterior Foundation Waterproofing in New Bedford
Exterior foundation waterproofing involves excavating around the foundation to apply a waterproof membrane or coating directly to the wall. This is often the most reliable 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. Rocky glacial soil and shallow ledge are common in Massachusetts, which can make digging for sewer and water lines slower and more expensive. Proper drainage solutions, such as French drains, are also added to divert water away.
Shower Wall Waterproofing in New Bedford
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.
Foundation Crack Repair in New Bedford
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 early in New Bedford homes is important to avoid larger, more costly structural issues.
Exterior Block Wall Waterproofing in New Bedford, MA
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 for good.
Foundation Crack Repair & Sealing in New Bedford
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.

Interior Walls Waterproofing in New Bedford, MA
Interior walls waterproofing focuses on managing water that has already penetrated the foundation walls. This usually 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 effectively stops it from pooling inside your living space. This solution is less disruptive than exterior excavation and is suitable where exterior access is limited.

Frequently Asked Questions About Walls Waterproofing in New Bedford
The cost of walls waterproofing in New Bedford, MA can vary a great deal 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 transparent, itemized quotes after a thorough inspection.
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 point to potential water entry issues. If you notice any of these, it's wise to get a professional assessment.
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.
Walls waterproofing is a key 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.
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.
For extensive walls waterproofing projects involving excavation, structural changes, or major changes to drainage systems, a permit from the city of New Bedford may be required. Simple crack repairs typically do not need a permit. BWM Plumbing will help you determine if a permit is necessary for your project and assist with the application process if needed.
Key signs you need walls waterproofing include damp or wet basement walls, visible mold or mildew growth, a musty odor in your basement or crawl space, efflorescence on concrete walls, cracks in the foundation, or standing water after heavy rains. Don't ignore these indicators, as they often point to ongoing water intrusion.
We commonly install Schluter Kerdi, Custom RedGard, Laticrete Hydro Ban and similar systems. The right choice depends on your shower design and tile. We follow each manufacturer's installation steps to keep the warranty in force.
