NYC bathrooms face heavy use, tight footprints, and strict codes. Skipping waterproofing is a false economy. At JJS Management Inc., every wet area gets a complete waterproofing system — membranes, sealed corners, proper overlaps, and flood testing where appropriate.
Why it matters:
- Protects subfloors and framing from rot and mold.
- Prevents tile failures and grout cracking.
- Speeds inspections and reduces warranty issues.
We specify the right products for your tile/stone and ensure installers follow manufacturer details to the letter. You may not see the membrane, but you’ll feel the peace of mind.
