Why do bathrooms and kitchens need waterproofing?

Bathrooms and kitchens have high moisture levels. Proper waterproofing prevents leaks, mold, and long-term structural damage.

How long does bathroom or kitchen waterproofing take?

Most waterproofing jobs take 1–2 days depending on the size of the area and the extent of the work needed.

Do you offer leak detection if I’m not sure where the water is coming from?

Yes. We use moisture meters and detection tools to locate hidden leaks before sealing the area.

Is waterproofing required before tiling?

Yes. A waterproof membrane should always be installed before tiles to prevent water from seeping underneath.

Do you offer a warranty for waterproofing services?

Yes. All waterproofing services come with a workmanship warranty depending on the materials and system installed.

Bathroom & Kitchen Waterproofing in New York City

Bathrooms and kitchens deal with more water than any other rooms. If water leaks into walls, floors, or under tiles, it can cause damage that spreads fast. You may not see the leak right away, but the effects grow over time. Wet drywall, loose tiles, mold, and musty smells are all signs something is wrong. We provide full waterproofing for bathrooms and kitchens in New York City. We work in Manhattan, Bronx, Queens, Brooklyn, and surrounding areas. We seal wet areas, protect tile surfaces, and stop mold from forming. Whether you're remodeling or fixing a leak, we help keep your space clean, dry, and safe.

Why Waterproof Bathrooms and Kitchens?

These rooms are used every day. They have sinks, showers, tubs, toilets, and dishwashers. All these fixtures connect to water. If something leaks, it can affect the walls, floors, and the space below.

Waterproofing helps prevent:

Proper waterproofing protects your home and your health. It also helps your surfaces last longer and look better.

Common Water Problems We See

New York City homes and apartments face many types of water issues. Here are some we handle often:

Leaking Shower Floors
Tiles may look fine, but water slips through cracks in the grout. Over time, it reaches the wood or cement under the tile.
Loose or Hollow-Sounding Tiles
This may mean water has reached under the surface. It weakens the glue that holds the tile.
Wet Cabinets or Vanity Bases
Leaks under the sink or around the faucet can soak the wood base and cause swelling or mold.
Mold in Grout or Corners
Mold grows in wet spots that don’t dry well. It often appears in the corners of tubs or behind toilets.
Ceiling Stains Under Bathrooms
If water is leaking through the floor, it can drip into the room below. This causes stains, peeling paint, or soft drywall.

Toilet base edges

Tile Sealing and Grout Protection

Tiles are not fully waterproof. Water can pass through grout lines or cracked corners. We seal the grout and tiles to block moisture and protect your walls and floors.

Steps We Take:

We work with ceramic, stone, and porcelain tiles.

Meld Protection and Removal

Mold grows fast in warm, wet areas. It can harm air quality and spread if left untreated. We remove mold, clean the surface, and seal the area to stop it from coming back.

Mold Prevention Steps:

If the leak caused mold behind walls, we can open the area, fix it, and reseal it.

Subfloor and Underlayment Protection

Water may also seep through the floor and damage the layers below. We inspect under tile, vinyl, or wood surfaces for signs of damage.

We Offer:

This is great for bathrooms on second floors or apartments with people living below.

Water and steam from cooking can damage cabinets and walls. We seal backsplashes, sinks, and counter edges to stop water damage.

We Focus On:

We also help during kitchen remodels to waterproof new installations.
