Google ReviewsKeep Water Out of Your Basement for Good
In Ronkonkoma, a lot of basement leaks show up in spring, when snow melts quickly and the ground around the house is already saturated. Meltwater and heavy spring rain both press against the foundation, and any weak point in the walls or floor lets it in.
Promaster Maintenance Corp waterproofs foundations and basements across Ronkonkoma, from the streets around the lake to the neighborhoods near the station. We also work in Lake Grove, Holbrook, Bohemia and Centereach.

Signs Your Foundation Needs Waterproofing in Ronkonkoma
After a thaw or a spell of heavy rain, check your basement for:
- Water or dampness on the floor or walls
- Cracks in foundation walls or floors
- White, chalky efflorescence on concrete or block
- Peeling paint or bubbling on basement walls
- A musty smell or visible mold
Each of these is a sign of moisture moving through your foundation, and it will get worse if it is left.
Exterior Foundation Waterproofing in Ronkonkoma, NY
Exterior waterproofing stops water before it can reach the walls. 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 grading so snowmelt and rain run away from the house
Treating the outside of the wall gives the most thorough, long-term protection.
Interior Basement Waterproofing and Drainage in Ronkonkoma, NY
Where excavation is not practical, an interior system manages the water that reaches the basement. We install:
An interior system relieves the hydrostatic pressure that pushes water through cracks during a spring thaw.
- Sump pumps that remove collected water automatically
- French drains that collect water along the foundation
- Interior waterproofing coatings and sealants
