EXTERIOR LEAKS • FACADE WATERPROOFING • CAULKING • COATINGS

Waterproofing Contractor in NYC

Exterior waterproofing and leak-correction services for New York City buildings. We address water entry at masonry walls, parapets, joints, penetrations, roof-to-wall transitions and other vulnerable exterior conditions across all five boroughs.

Exterior Waterproofing & Leak Repair

Effective waterproofing starts with identifying how water is reaching the building. Exterior deterioration, failed joints, open masonry, cracked coatings, parapet conditions and roof transitions can all contribute to leaks.

  • Exterior wall and facade waterproofing
  • Caulking and sealant replacement
  • Waterproof coatings and protective finishes
  • Parapet and coping waterproofing
  • Window perimeter, lintel and sill conditions
  • Masonry joint and crack repair
  • Roof-to-wall transition waterproofing
  • Leak-related facade and building-envelope repairs

Waterproofing Works Best With the Right Repairs

Coatings and sealants cannot permanently correct loose brick, failed mortar, damaged parapets or other deteriorated substrates. When masonry or facade repairs are needed first, our team can combine those repairs with the waterproofing scope for a more complete exterior solution.

Waterproofing in Manhattan, Brooklyn, Queens, Bronx & Staten Island

We provide exterior waterproofing for residential, commercial and multifamily properties throughout NYC. Projects can be coordinated with facade restoration, roofing and Local Law 11 / FISP repairs.
