Waterproofing for Older Homes in Somerville, MA
Older homes, especially those built before modern waterproofing standards, are especially prone to water intrusion. The housing stock in Massachusetts is among the oldest in the country, with many homes built before modern plumbing materials existed. 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.
Crawl Space Vapor Barriers in Somerville
Many homes in Somerville have crawl spaces, which are very prone to moisture issues. Installing a heavy-duty vapor barrier on crawl space walls and floors is a key waterproofing strategy. This thick polyethylene sheeting prevents ground moisture from evaporating into the crawl space, protecting subflooring and joists and improving indoor air quality. It's an affordable way to control humidity and prevent wood rot.
Below-Grade and Basement Wall Waterproofing in Somerville
The housing stock in Massachusetts is among the oldest in the country, with many homes built before modern plumbing materials existed. 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 in Somerville
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 Somerville homes is important to avoid larger, more costly structural issues.
Laundry Room and Utility Wall Waterproofing in Somerville, MA
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 Somerville, 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 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.

Frequently Asked Questions About Walls Waterproofing in Somerville
The cost of walls waterproofing in Somerville, MA 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 influence the final price. We provide detailed, transparent quotes after a thorough inspection.
For extensive walls waterproofing projects that involve excavation, significant structural changes, or changes to drainage systems, a permit from the Somerville 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.
Yes, BWM Plumbing stands behind the quality of our work. We offer full warranties on our walls waterproofing installations, covering both materials and labor. The warranty details will be outlined in your service agreement, giving you confidence about your investment. Our goal is your complete satisfaction and a dry, healthy home.
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 first visit.
Walls waterproofing is generally not recommended as a DIY project due to its complexity and the high 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 highly advisable.
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.
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 valid.
While minor DIY fixes like patching small cracks are possible, complete walls waterproofing is best left to professionals. It involves specialized knowledge of drainage, foundation mechanics, and proper material application. Improper DIY work can lead to poor results, wasted money, and worse water damage over time.
