Google ReviewsKeep Water Out of Your Basement for Good
On Huntington's North Shore hills, rain does not soak in where it falls. It runs downhill, and on a sloping lot it often ends up pressing against the uphill side of the foundation. Add older foundations in many of the homes near the village, and it is easy to see why so many Huntington basements struggle with water.
Promaster Maintenance Corp waterproofs foundations and basements across Huntington, stopping water at the source rather than just mopping up after it. We also serve Huntington Station, Greenlawn, Centerport and Cold Spring Harbor.

Signs Your Foundation Needs Waterproofing in Huntington
On a hillside property, water problems often show up first on the uphill wall. Call us if you see:
- Cracks in foundation walls or floors
- Water or dampness on basement walls, often along one side
- Peeling paint or bubbling on basement walls
- White, chalky efflorescence on concrete or block
- A musty smell or visible mold
Each of these means moisture is moving through the foundation, and the problem grows with every heavy rain.
Exterior Foundation Waterproofing in Huntington, NY
The International Residential Code requires below-grade foundation walls to be dampproofed, and waterproofed where groundwater is high. On a slope, the drainage step carries extra weight. Our process is:
- Excavating along the foundation to expose the walls
- Cleaning and repairing cracks in the concrete
- Applying a waterproofing membrane or bentonite barrier
- Installing drainage that intercepts water coming downhill and carries it away
- Backfilling and grading so surface water is directed away from the house
Waterproofing from the outside is the most thorough way to protect a foundation that takes runoff from higher ground.
Interior Basement Waterproofing and Drainage in Huntington, NY
On steep or tight Huntington lots, excavating is not always possible. An interior system manages the water that reaches the basement. We install:
Interior drainage relieves the hydrostatic pressure that builds up when water collects against a wall on a slope.
- French drains along the foundation to collect water
- Interior waterproofing coatings and sealants
- Sump pumps that remove collected water automatically

Older foundations and the pressure of water from uphill can both open cracks. We repair:
- Foundation wall cracks
- Leaks around pipes and wall joints
- Basement floor and slab cracks
We look at whether a crack comes from settling or structural movement before deciding how to repair it.
Crawl Space Repairs and Foundation Underpinning
Older Huntington homes sometimes have crawl spaces or foundations that have settled over the years. We provide:
- Crawl space repairs for moisture, rot and damaged supports
- Foundation underpinning to stabilize settling or sinking foundations
Stabilizing the structure first lets waterproofing do its job properly.
