Basement Waterproofing & Foundation Repair in Somerville, NJ

Preserving Somerville's Historic Homes from Water Damage

Somerville is the vibrant, historic heart of Somerset County. Known for its bustling downtown and beautiful, tree-lined streets, the borough features a rich mix of architectural styles, including many stately Victorian and early 20th-century homes. While these older homes offer incredible charm and character, their aging foundations — often constructed from stone, brick, or early concrete block — are highly susceptible to water intrusion and structural deterioration.

At Down Under Waterproofing & Foundation Repair, we have the specialized knowledge required to protect and preserve older homes in Somerville. Since 2006, we have been providing expert waterproofing and foundation repair services that respect the historical integrity of your property while delivering modern, permanent solutions to water problems.

Our Services for Somerville, NJ Homeowners

We offer a complete range of services tailored to the unique needs of Somerville's older housing stock.

💧 Basement Waterproofing

Older foundations were rarely built with modern waterproofing standards in mind. Over decades, mortar joints deteriorate, allowing groundwater to seep into the basement. We install comprehensive interior French drain systems and reliable sump pumps that capture and redirect water before it can damage your basement. Our solutions keep your space dry, preventing mold and protecting your stored belongings.

🏛 Foundation Repair

If you own a historic home in Somerville, you may notice signs of foundation settling, such as uneven floors, sticking doors, or stair-step cracks in the exterior brickwork. We specialize in stabilizing aging foundations. Using advanced techniques like carbon fiber strapping and wall anchors, we can halt foundation movement and restore the structural integrity of your home without compromising its historic character.

🏠 Crawl Space Encapsulation

Many older homes feature dirt-floor crawl spaces that constantly emit moisture into the home, leading to musty odors and wood rot in the floor joists above. Our crawl space encapsulation service completely seals the area with a heavy-duty vapor barrier. We also install dehumidifiers to control moisture levels, improving your home's indoor air quality and protecting its structural wood.

🔨 Construction Restoration

Somerville's older homes often suffer from decades of moisture exposure that has weakened structural wood components. We replace sill plates, level sagging floors, repair termite and rot damage, and replace columns, support beams, and girders. Our construction restoration work addresses the underlying structural issues that allow water problems to continue unchecked.

🌋 Above Grade Waterproofing

Water doesn't only enter from below — it also penetrates through the building envelope above grade. We apply professional waterproofing coatings, caulking, and flashing to seal your home's exterior walls, window frames, and penetration points, stopping water before it reaches your foundation or interior walls.

🧱 Masonry Repair & Restoration

The exterior masonry of older homes requires careful maintenance. Harsh weather and time can cause brick faces to spall and mortar to crumble. Our expert masons provide meticulous repair and repointing services. We restore brick, stone, and concrete surfaces — including chimney repair, step rebuilding, and block work — ensuring they are structurally sound and visually appealing.

🏠 Stucco Repair & Application

If your home features stucco siding, cracks and water damage can quickly lead to severe underlying issues. We offer professional stucco repair and re-coating services that seal your home's exterior envelope against driving rain and moisture penetration, preserving the historic look of your Somerville home.

🌋 Retaining Walls

Managing exterior drainage is especially important for older properties in Somerville where original grading may have settled over the decades. We design and install structural retaining walls that prevent soil erosion, manage runoff, and reduce hydrostatic pressure on your foundation walls.

🚪 Bilco Doors & Egress Windows

Replacing old, leaky basement doors is a simple way to improve your home's water resistance. We install modern, weather-tight Bilco doors and egress windows that provide secure access, natural light, and keep the elements out year-round.
