Google ReviewsKeep Water Out of Your Basement for Good
Water is one of the biggest threats to your home’s foundation. Promaster Maintenance Corp provides foundation waterproofing that keeps basements dry, stops leaks at the source, and protects the structure your home is built on. We work with homeowners throughout Huntington and the surrounding Suffolk County communities.
Signs Your Foundation Needs Waterproofing in Huntington
Foundation water problems usually start small and get worse with every heavy rain. Call us if you notice:
- Water or dampness on basement floors or walls
- White, chalky efflorescence on concrete or block
- Cracks in foundation walls or floors
- A musty smell or visible mold
- Peeling paint or bubbling on basement walls
Each of these signs points to moisture moving through your foundation, and the longer it continues, the more damage it causes.
Exterior Foundation Waterproofing
Exterior waterproofing stops water before it reaches your foundation walls. The International Residential Code requires below-grade foundation walls to be dampproofed, and fully waterproofed where groundwater levels are high. Promaster Maintenance Corp follows a careful and proven process:
- 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 water away
- Backfilling and grading so surface water flows away from your home
Because it treats the outside of the wall, exterior foundation waterproofing is widely considered the most thorough way to keep water out for the long term.
Interior Basement Waterproofing and Drainage
When excavating isn’t practical, interior systems manage water that reaches the basement. Promaster Maintenance Corp installs:
Interior drainage relieves the hydrostatic pressure that pushes groundwater through cracks and joints, keeping your basement dry and usable.
- Interior waterproofing coatings and sealants
- French drains that collect water along the foundation
- Sump pumps that remove collected water automatically

Even small cracks give water a direct path into your home. We repair:
- Foundation wall cracks
- Basement floor and slab cracks
- Leaks around pipes and wall joints
We also check whether a crack is caused by settling or structural movement, because that changes the right repair.
Crawl Space Repairs and Foundation Underpinning
Some water problems cause damage that goes beyond a wet basement. Promaster Maintenance Corp provides:
- Crawl space repairs for moisture, rot and damaged supports
- Foundation underpinning to stabilize settling or sinking foundations
Stabilizing the structure first helps your waterproofing perform as it should.
