Short answer: drywall repair cost depends less on how big the mark looks than on how much of the wall or ceiling has to be rebuilt to make it disappear. A nail pop or a fist-sized hole is a surface patch. A door-knob hole or a failed seam needs a backing piece or new tape, and a water-stained or sagging ceiling needs a section cut out and replaced. Repairs cost least when every dent and crack in the house is done at once, and least of all when they are the first step of a repaint. We do not take drywall repair as a stand-alone job; we fix patches, cracks and nail pops, and replace damaged sections, as part of painting the room. Below: the three levels of damage, what each kind needs, when a patch stops making sense, and how repairs fit into a painting quote.
What drives drywall repair cost: three levels of damage
In practice, almost all damage falls into three levels.
| Level | Typical damage | What the fix involves |
|---|---|---|
| Surface patch | Nail pops, small holes, hairline cracks | Holes up to fist size filled, taped and feathered, sanded smooth and prime-ready |
| Larger patch | Big holes, failed seams, damaged corner bead | Door-knob holes with backing, seams and corners re-taped, blended flush with the wall |
| Section replacement | Stained ceilings, soaked board, sagging | Cut-back and board replacement, stain-blocking primer, overhead and textured ceilings |
The rest of this article matches common damage to its level. Where painter’s prep ends and repair begins is set out in our guide to wall prep before painting.
Drywall repair by type of damage
- Nail pops and screw pops — the fastener is reset or replaced beside the pop, the crater filled and feathered. Usually there are a dozen in a house once you look, which is why they are done as a group.
- Hairline cracks — cracks at door and window corners are taped, not just filled, so they do not come back the next winter. A crack that keeps reopening along a straight line is a failed seam and needs re-taping.
- Small holes, up to fist size — filled, taped, feathered and sanded to a prime-ready surface.
- Door-knob holes and larger — a backing piece goes in behind the opening, a new section of board is fitted, then taped and blended flush. A door stop is worth adding so it does not happen again.
- Corner bead — dented or cracked outside corners get the bead cut out, replaced and re-mudded along the full length so the repair does not show as a bump.
- Failed seams — bubbling or lifting tape is cut out, the joint is re-taped and coated in two or three passes.
- Water-stained ceiling — the stained section is cut back to sound board, replaced, taped and sealed with a stain-blocking primer.
- Sagging or soaked ceiling — sagging board has lost its strength and comes out; anything wet behind it is dried before the new section goes in.
- Patching a popcorn or stippled ceiling — overhead and textured work is slower, and the new texture has to be blended into the old. The options for a popcorn ceiling — removal, skim-coating and repair — are in our guide to popcorn ceiling removal.
- Whole rooms or full skim coats — at that point the job is closer to re-boarding or skim-coating the whole surface than to a repair.
Why repairs cost least as part of a repaint
A single nail pop takes a few minutes of actual work but a full visit: travel, setup, drop sheets, two or three coats of compound with drying time between them, sanding and cleanup. That visit costs the same for one patch or twelve, and a patched wall still looks patched until it is painted. Both problems go away when the repairs are the first step of painting the room, which is the only way we do them. Basic filling and caulking is inside every interior painting package. Larger repairs, up to cutting out and replacing a damaged section of board, are listed as their own lines in the same written quote, before work begins.
Before you ask for a price, walk the house with painter’s tape and mark every pop, dent, crack and scuffed corner. The list goes into the quote, and nothing on it turns into a surprise halfway through the job.
Repair or replace: when a patch stops making sense
A patch is the right call when the board around the damage is dry, solid and flat. It is the wrong call in three situations:
- The board is wet or has been wet for days. Gypsum that has soaked loses its strength and the paper face lets go. Once it sags or crumbles at the edge of the hole, the damaged section has to come out regardless of what the stain looks like.
- There is mould behind or on the board. Sealing it in is not a repair. The affected board comes out, the cavity is dried and treated, and new board goes in.
- More than about a third of the wall is damaged. At that point you are paying repair rates for what is really a re-sheet. Replacing the board is usually cheaper and gives a flatter result than a patchwork of repairs.
Ceilings and water damage: the order matters
A stain on the ceiling is a symptom. Before any repair, the leak — a roof, a bathroom above, a plumbing joint, ice damming at the eaves — has to be found and stopped, and the cavity has to dry. A repair done over a live leak fails within weeks. Once it is dry, the process is cut-back to sound board, new board fitted and taped, then a stain-blocking primer over the whole repair. That primer is the step people skip when they try to just paint over the stain: water stains bleed straight through ordinary paint, sometimes after the second coat looks fine, and the yellow ring returns. Overhead work is slower than wall work and textured ceilings need the texture matched, which is why the same damage costs more on a ceiling than on a wall.
Older homes: plaster and lath
Century houses in Toronto, Hamilton and the older parts of Mississauga and Brampton have plaster over wood lath rather than drywall. The damage looks different — cracks that follow the lath lines, sections that sound hollow, plaster keys that have broken away — and so do the fixes:
- Patch a crack or a small hole with a bonding agent and setting compound, then feather it out.
- Skim a wall that is sound but rough or map-cracked all over; this is a whole-surface job rather than a patch.
- Replace a section that has separated from the lath or is soft with moisture, usually with drywall shimmed to the plaster thickness.
Plaster damage is harder to judge from a photo than drywall, because what is behind the surface is not visible. If you are in a pre-1950s house, say so when you send pictures of the rooms you want painted.
Drywall damage we see across the GTA
- Toronto — condo scuffs and door-knob holes, plaster in the older semis, and building rules for access. See interior painting in Toronto.
- Mississauga — settling cracks and nail pops in 1980s–2000s houses, usually fixed as the first step of a repaint. See interior painting in Mississauga.
- Brampton — newer builds with builder-grade taping that lets go at corners and seams within the first few years. See interior painting in Brampton.
- Hamilton — plaster and lath, water damage from older roofs and flat-roof additions. See interior painting in Hamilton.
How to get repairs priced into a painting quote
- Take a photo of each repair straight on, with something for scale — a hand or a tape measure works.
- Count them. Six nail pops and one hole is a different job from one hole.
- Say whether the ceiling or wall has been wet, and whether the leak is fixed.
- Say which rooms you want painted. Repairs beyond basic prep in those rooms go into the same written quote, each as its own line.
IntraBuild fixes patches, cracks, nail pops and damaged sections of board as part of interior painting across Toronto, the GTA and Southern Ontario, not as a stand-alone repair visit. Send photos of each room and each repair, and we reply the same business day. With damage in the photos, we price the job after a walkthrough, which is free anywhere we work and carries no obligation. Anything beyond basic prep appears in the written price as its own line. There is no distance charge; some farther addresses have a higher smallest project, and we tell you the figure before the quote. The person who quotes your job is responsible for it.

Frequently asked questions
How much does it cost to fix a hole in drywall?
It depends on the size and what is behind it. Up to fist size, the hole is filled, taped, feathered and sanded. A door-knob hole needs a backing piece and an insert, taped and blended flush. We fix both as part of painting the room.
Do you do drywall repair on its own?
No. We fix patches, cracks and nail pops, and replace a damaged section of board where it is needed, only as part of painting a room. Basic filling and caulking is inside every painting package, and larger repairs are their own lines in the same written quote. We do not book a stand-alone repair visit.
Can a water-damaged ceiling be repaired without replacing it?
Sometimes. If the board is dry, flat and firm and only the surface is stained, the section is sealed with a stain-blocking primer and refinished. If it is soft, sagging or has been wet for more than a day or two, the damaged section is cut back and replaced.
How long does drywall repair take?
Most surface patches and larger patches are finished in one day, with drying time between coats built in, before the paint goes on. A replaced ceiling section needs extra drying time for its final coat and primer, so it is finished before any painting starts.
