Drywall

Drywall and plaster repair, skim coating and new partitions

We repair, skim and build interior walls and ceilings in New York homes: patching cracked plaster, replacing water-damaged drywall, flattening walls for paint and framing non-structural partitions. Each scope names the finish level the walls will get, so the result matches the paint sheen and the light in the room.

Scope

What the work can include

Every project is scoped individually. This is what is typically part of the work, not a package.

  • Patching holes, cracks and failed tape joints in drywall and plaster
  • Replacing sections damaged by a leak once the leak has been repaired
  • Skim coating uneven or patched walls before paint
  • Ceiling repair and new drywall ceilings below existing framing
  • Non-structural partitions, closets and soffits where the layout allows
  • Finish level agreed in writing for each room

New York homes

What is different here

  1. Plaster walls in pre-war houses

    In Brooklyn, 48.4% of housing units were built in 1939 or earlier, and many pre-war houses across the boroughs still have plaster on lath. Plaster cracks along lath lines and around door heads, and patching it with drywall compound alone often shows. We decide per wall whether to repair the plaster, skim it, or overlay it with new board, and say which in the scope.

  2. Ceiling stains below bathrooms and roofs

    In a two-family house or an attached rowhouse, a stain on a ceiling can come from the unit above, a shared wall or the roof. We do not cut and patch a stained ceiling until the source has been found and fixed, because a new patch over a live leak fails the same way. Roof and exterior repairs are outside our services, so that fix sits with the right trade before we return.

  3. New partitions in older layouts

    Splitting a large bedroom, adding a closet or boxing in pipes is common in older New York houses. Before we frame, an architect or engineer has to settle anything that touches load, and new outlets in the wall are electrical work that may require an appropriately licensed electrician. In the city, if the partition goes beyond DOB's exempt work, a registered design professional has to file plans. We only take on partitions that carry no structural load.

Finish levels

Matching the finish level to the room

How we choose a finish level (based on National Gypsum's summary of GA-214)
Room or conditionLevel we usually proposeReason
Closets, utility rooms, behind tileTaped and filled to suit what covers itSurface will be hidden or tiled
Bedrooms and living rooms with flat paintLevel 4Recommended for flat paints and light textures
Walls with eggshell, satin or gloss paintLevel 5Recommended for non-flat and glossy finishes
Hallways and walls lit at a low angleLevel 5Recommended where critical lighting conditions occur
Dark or deep-tone colorsLevel 5Level 4 is not recommended under deep-tone paints

A Level 5 finish adds a thin skim over the whole surface, so it costs more time than Level 4. If you are still choosing paint, the interior painting page explains how sheen affects what the wall shows.

Before demolition

Older walls and what cutting into them involves

  • Unknown materials: EPA says asbestos cannot be identified by looking, and recommends inspection by an accredited professional before remodeling. We ask whether materials have been sampled before we open older walls or ceilings.
  • NYC permitted work: when a job needs DOB alteration permits, the city first requires a Certified Asbestos Investigator's finding on whether it counts as an asbestos project.
  • Painted surfaces: sanding or cutting painted plaster in a home built before 1978 is paint disturbance, so we follow EPA lead-safe practices with certified renovators.
  • Permits: DOB lists plastering among jobs that need no work permit; partitions with new wiring are a different case and are filed accordingly.

Process

How a project runs

Written scope, written proposal, permits identified up front, and one project lead from start to finish.

  1. Conversation

    You describe the home and what you want to change. We ask about budget range and timing so expectations are clear early.

  2. Site visit and scope

    We look at the space, the structure of the house and any HOA, co-op or condo rules that apply, then write a scope of work.

  3. Design and selections

    Layout, materials and fixtures are agreed in writing before work is priced in full.

  4. Written proposal

    A written price and schedule for the agreed scope. Permits and any approvals are identified at this stage.

  5. Build

    One project lead coordinates the trades and keeps you updated. Some regulated work may require appropriately licensed specialty contractors.

  6. Walkthrough

    We review the finished work with you and resolve anything outstanding.

Questions

Common questions

Should cracked plaster be repaired or replaced with drywall?
It depends on how well the plaster is still attached to the lath. Sound plaster with surface cracks can usually be taped, skimmed and kept, which preserves trim and window casings. Plaster that is loose or bulging over a wide area is often better removed or overlaid. We press-check each wall during the site visit and price the option that suits it.
What does a finish level mean for my walls?
Finish levels describe how much tape and compound goes on drywall, from Level 0 to Level 5 in the Gypsum Association's GA-214. As National Gypsum summarizes it, Level 4 suits flat paint and light textures, while Level 5 is recommended for glossy or deep-tone paints and where critical lighting occurs, such as light raking across a wall from a window. We name the level in your scope.
Can you add a wall to divide a room?
Yes, when the wall carries no structural load and the rooms on both sides still work. Our project lead confirms the framing direction, the outlets the new wall will need and whether the change brings a filing. Anything load-bearing goes to an engineer or architect first, and structural changes are not part of our drywall service.
How long does skim coating take?
Most rooms need two or three thin coats, each sanded once dry, before primer goes on. Drying time depends on humidity and ventilation, so we schedule skim coating as its own phase and let you know which rooms will be closed off while it cures.
Do you repair ceilings with sagging plaster?
We assess it first. A ceiling that has pulled away from its lath can fall, so we keep people out of the room until it is secured or taken down under containment. If the sag comes from framing rather than the plaster itself, it becomes a structural question for an engineer before we close anything up.
