Google ReviewsKeep Water Out of Your Basement for Good
Medford's light, sandy soil on the edge of the Pine Barrens drains quickly, so many homeowners are surprised when their basement gets wet. The usual culprits are grading that slopes toward the house and roof water dumped right beside the foundation, and on loose sandy ground, years of water can also leave a foundation settling.
Promaster Maintenance Corp waterproofs foundations and basements throughout Medford, stopping leaks at the source and stabilizing foundations where needed. We also work in nearby Coram, Farmingville, Holtsville and Selden.

Signs Your Foundation Needs Waterproofing in Medford
Even on well-drained ground, check your basement for:
- Cracks in foundation walls or floors, including new ones
- Water or dampness on basement floors or walls
- White, chalky efflorescence on concrete or block
- A musty smell or visible mold
- Peeling paint or bubbling on basement walls
These all point to moisture moving through the foundation, and the damage grows the longer it continues.
Exterior Foundation Waterproofing in Medford, NY
Exterior waterproofing stops water before it reaches the walls, and on a Medford lot, the grading is often half the fix. 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 water away
- Backfilling and regrading so surface water flows away from your home
Correcting the grading at the same time stops water being directed back toward the foundation.
Interior Basement Waterproofing and Drainage in Medford, NY
Where excavation is not practical, an interior system manages water that reaches the basement. We install:
Interior drainage relieves the hydrostatic pressure that pushes water through cracks and joints.
- French drains that collect water along the foundation
- Sump pumps that remove collected water automatically
- Interior waterproofing coatings and sealants

On sandy soil, cracks can come from water or from the foundation settling. We repair:
- Foundation wall cracks
- Leaks around pipes and wall joints
- Basement floor and slab cracks
We check whether a crack is caused by settling or structural movement, because that changes the repair, and sometimes means the foundation needs stabilizing first.
Crawl Space Repairs and Foundation Underpinning
Loose, sandy ground can let a foundation settle over time. Promaster Maintenance Corp provides:
- Foundation underpinning to stabilize settling or sinking foundations
- Crawl space repairs for moisture, rot and damaged supports
Once the structure is stable, your waterproofing can do its job.
