Google ReviewsKeep Water Out of Your Basement for Good
Many Montauk homes sit empty for long stretches of the winter, and that is exactly when Atlantic storms soak the sandy ground around them. Water can seep into a basement or crawl space for weeks before anyone notices, and the first sign is often a musty smell when the house is opened up in spring.
Promaster Maintenance Corp waterproofs foundations and basements for Montauk homeowners, stopping leaks at the source so the house is dry when you arrive. We also work in nearby Amagansett, Springs and East Hampton.

Signs Your Foundation Needs Waterproofing in Montauk
When you open the house each season, check the basement for:
- A musty smell or visible mold
- Water stains or dampness on floors or walls
- Peeling paint or bubbling on basement walls
- White, chalky efflorescence on concrete or block
- Cracks in foundation walls or floors
All of these show moisture moving through the foundation, and in an empty house the damage can build up unnoticed.
Exterior Foundation Waterproofing in Montauk, NY
Exterior waterproofing stops water before it reaches the foundation. The International Residential Code requires below-grade foundation walls to be dampproofed, and waterproofed where groundwater is high. 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 to carry storm water away
- Backfilling and grading so surface water flows away from the house
For a house that is not occupied all year, exterior waterproofing gives the most thorough protection.
Interior Basement Waterproofing and Drainage in Montauk, NY
Where excavation is not practical, an interior system manages the water that reaches the basement. We install:
Interior drainage relieves the hydrostatic pressure that pushes water through cracks and joints during winter storms.
- Interior waterproofing coatings and sealants
- Sump pumps that remove collected water automatically
- French drains that collect water along the foundation
