About bros

Protecting Boston Homes From Water Issues

We’re Boston’s basement waterproofing specialists. We’ve been fixing wet basements and foundation problems across the city, helping homeowners protect their homes from water damage.

Why Boston Basements Leak

Boston sits on a mix of clay and sandy soils that don’t drain well. Most Boston homes were built between the 1800s and early 1900s—long before modern waterproofing existed. Those old brick and stone foundations crack over time. Mortar deteriorates. Water seeps through. You see it as puddles on your floor, damp walls, or white mineral deposits on concrete.

Coastal storms dump inches of rain in hours. Winter freeze-thaw cycles crack foundations wider each year. All of this pushes water into basements across South Boston, Dorchester, Jamaica Plain, Back Bay, Charlestown, Roxbury, Brighton, and every neighborhood in between.

Prevent Costly Water Damage

Water doesn’t stop on its own. Foundation cracks grow. Mold spreads behind walls. Taking steps to protect your home from flooding prevents small problems from becoming expensive repairs. Home value drops when water damage goes unchecked.

How We Help

We inspect every basement thoroughly. We tell you exactly what’s wrong and why. We recommend the solution that fits your home—not the most expensive option. Bros Basement Waterproofing works in brownstones, triple-deckers, and colonial homes across Boston.

Basement Waterproofing

We stop water from entering your basement. Interior and exterior waterproofing systems protect your foundation and keep your space dry. This includes drainage installation, crack sealing, wall coatings, membrane systems, and moisture barriers.

Foundation Repair

We fix structural problems in your foundation. Cracks, bowing walls, and settlement issues get permanent repairs. Our work includes epoxy injection, carbon fiber reinforcement, wall anchors, steel beam installation, underpinning, and foundation stabilization.
