Alliance General Contracting NY Inc is a licensed and fully insured contractor operating out of 2362 Westchester Ave in the Bronx. Bathroom Vanity Installation is one of the services our bathroom remodeling division performs week in and week out, and searching for vanity installation Manhattan or bathroom vanity installation near me should bring you to a team that actually works in your neighborhood rather than a call center three states away.

In pre-war NYC apartments and rowhouses we routinely find original mud-set tile over wood lath, galvanized supply lines near the end of their life, and no vent fan at all. We replace supply and waste lines within the wall while it is open, install a sheet or liquid waterproofing membrane instead of relying on cement board alone, and vent to the exterior rather than into a joist bay.

What's Included

  • Wall blocking installation
  • Plumbing rough adjustment
  • Vanity leveling and anchoring
  • Top and sink setting
  • Faucet and drain hookup
  • Backsplash and caulk finish

Why NYC Properties Need Bathroom Vanity Installation

Bathrooms are the smallest rooms we build and the least forgiving. Waterproofing, slope, ventilation and substrate all have to be right, because a shortcut behind a tile wall shows up two years later as a stain on the ceiling below. Alliance General Contracting NY Inc remodels bathrooms throughout the Bronx, Brooklyn, Queens and Manhattan with proper waterproof membranes, correctly sloped pans and ventilation that actually exhausts outdoors.

Across the four boroughs we work on two-family brick homes, pre-war walk-ups, semi-detached row houses and mixed-use storefront buildings; limestone and brownstone rowhouses, three-family frame homes and converted industrial lofts; attached brick colonials, Tudor-style singles, garden co-ops and two-family investment properties; pre-war co-ops, brownstone conversions, tenement-era multifamily buildings and high-rise condo interiors. Each of those building types ages differently, and bathroom vanity installation is specified accordingly what suits a detached Bayside colonial is not what suits a shared-wall Bed-Stuy rowhouse or a fifth-floor pre-war apartment in Washington Heights. That judgment is the part you are really hiring a licensed contractor for.

Signs You Need Bathroom Vanity Installation Now

Property owners usually call us after they notice one of the following: visible staining or discoloration on interior finishes, a musty smell that returns after every rain, hairline cracking that keeps widening season over season, materials that are loose, spalling, sagging or separating, rising utility bills that suggest a compromised building envelope, or a condition flagged on an inspection or violation notice. None of these get cheaper with time. Water in particular finds a path and then keeps using it, and by the time damage is obvious the repair has usually doubled in scope.

If you are seeing any of that, book the free estimate. We will tell you honestly whether it is urgent, whether a targeted repair will do, or whether you can safely budget for it next season.

Timeline and What To Expect

After your free walkthrough you receive a written, line-item scope with materials named and allowances stated. Once you approve it we confirm material lead times, arrange any filings the work requires, and give you a start date with a realistic duration. On site we protect the surrounding areas before work begins, keep the space clean at the end of each day, and send you progress photos of anything that will be covered up. When the work is done we walk it with you and close out every punch item before invoicing the balance.

Permits and code compliance are handled as part of the job where applicable. New York City has real requirements around structural work, sidewalks, facades, plumbing and electrical, and doing it properly protects your resale, your insurance position and your neighbors.
