Why Do Loft Cellars in NoHo Leak?
NoHo cellars leak through old masonry walls with worn mortar, through sidewalk vault roofs and vault lights, and around pipe openings. There is no special flood exposure here beyond heavy rain, so the water usually comes from the building or the sidewalk above it.
Many loft buildings have a vault that extends under the sidewalk. Vault lights, the glass lenses set in the pavement, were meant to bring daylight below. As their frames corrode and lenses crack, rain and melt water drip straight into the vault.
- Dripping from the ceiling of a sidewalk vault
- Damp or powdery walls in a cellar
- Water at the base of a wall after storms
- Peeling paint and bubbling plaster
- Musty storage rooms and mechanical spaces
- Water near an old pipe or conduit opening
A wet cellar is not always a waterproofing job. Sewage rising through a drain is a plumbing problem, and we help you work out which problem you actually have.
Vault Dripping After Rain?
Tell us when it drips and where. The pattern often points straight to the cause.
How We Fix It
How Do You Stop Water Entering a Loft Cellar or Vault?
We trace the entry point first. Then we repair the cause: cracked masonry, open joints, failed vault lights, weak sidewalk flags or a bad pipe seal. After that, walls are sealed and, if needed, a drainage path is set up so water can leave the space.
When the vault lights are the path, the repair starts at the surface. Resetting frames, replacing broken lenses or covering a failed panel stops water at the source. Repairing the flags around them closes the other gaps.
Inside the cellar, sealing treats the wall face. Water pressure behind the wall can still push it off, so we check how the wall is built and whether drainage is needed. Outside access in this part of Manhattan is limited, so a mix of inside and surface repairs is common.
Each option has limits, and we go through them with you. Waterproofing reduces moisture problems, and the estimate states in writing what we will and will not address.
What Rules Apply to Waterproofing a NoHo Cellar or Vault?
Sealing walls from inside seldom involves the city. Structural work, work in a sidewalk vault or changes to the sidewalk above can need DOB or DOT approval. NoHo has two historic districts, where vault lights and other historic materials may be reviewed. The city can confirm which approvals your property needs.
Under Admin Code 19-152 the owner keeps the sidewalk in repair. A cracked flag or failed vault light is therefore both a violation risk and a leak path. Our sidewalk violations page explains what happens if DOT issues a notice.
A wall that cracks and moves is a structural matter. In that case a licensed engineer comes first, DOB permits may follow, and nobody can honestly promise a result up front.
A loft above six stories also carries Local Law 11 facade duties. Cellar work is a different scope, though one visit can sometimes serve both.
Do I need a sump pump?
Only if water collects beneath the floor with nowhere to go. We check the layout and tell you whether a pump makes sense or if repairing the leak is enough.

FAQ
NoHo Waterproofing Questions
Yes. Corroded frames and cracked lenses let rain pass through. Repairing or replacing them can stop much of the water.
Probably not. An overflowing drain points to the sewer line, which is plumbing work, usually with a backwater valve. Sealing a wall will not stop it.
Outside access is limited in NoHo, so inside work combined with surface repairs is common.
We cannot guarantee that. We repair the cause we find and say in writing what the work does and does not cover.
