Water gets into your foundation. We keep it out.
Foundation waterproofing, foundation repair, drainage, chimney, roof and step repair across Fairfield County and the New York suburbs. Licensed, bonded and insured. Free estimates, emergency and same-day service, and a 30-year warranty.
Everything between the roofline and the footing
Water damage rarely has a single cause. A wet basement is often a gutter problem, a grading problem and a foundation problem at the same time. These are the services we offer across all five counties.

Foundation Waterproofing
Interior and exterior systems that stop water at the wall instead of managing it after it is already inside. Membrane, drainage board, interior drain tile and crack injection.

Foundation Repair
Cracked, bowing, shifting or settling foundations, repaired at the structure rather than patched at the surface.
Learn more
Foundation Underpinning
When a footing is too shallow, undersized or sitting on soil that moved, underpinning takes the load down to ground that will actually hold it.

Sump Pump Installation
Correctly sized pumps, sealed basins, check valves, discharge lines that run far enough from the house, and battery backup for the storms that take the power with them.

French Drain Installation
Perforated pipe, washed stone and filter fabric, pitched properly and daylighted or tied into a pump. The single most effective thing you can do about groundwater.
Learn more
Chimney Repair
Repointing, crown rebuilds, flashing, waterproof sealing and full rebuilds. Most chimney leaks are a flashing or crown problem, not a roof problem.

Roof Repair
Leak diagnosis, flashing, valleys, shingle and slate repair, and emergency tarping when a storm opens something up overnight.

Step & Stoop Repair
Settled, cracked and spalling steps rebuilt or resurfaced, with the drainage problem that caused the damage corrected at the same time.
Learn moreYour basement has been telling you for a while
A house usually gives warning long before a basement floods. Efflorescence, a smell that returns every spring, a hairline crack that widened over two winters. These are early-stage symptoms of the same problem that can eventually put water on your floor.
None of these mean your house is falling down. They do mean water is moving where it should not be, and the repair only gets more expensive the longer it runs.
- A damp, musty smell that comes back every spring
- White chalky powder (efflorescence) on block or concrete walls
- Water tracking along the joint where the floor meets the wall
- Horizontal cracks, stair-step cracks or a wall that bows inward
- Doors and windows that stick on one side of the house
- A sump pump that runs constantly, or one that never runs at all
- Standing water against the foundation after rain
- Mold on the bottom of boxes, drywall or stored furniture

A failed sump pump during a storm, a cracked foundation wall letting water across the slab, a roof opened up overnight. We offer emergency and same-day service, because standing water does more damage the longer it sits.
