Drywall damage is one of the most common home repair requests in Toronto — and one of the most varied. A tiny nail hole from a removed picture frame is completely different from a fist-sized hole from a doorknob or a water-damaged section that needs full replacement.
Here's an honest guide to help you decide: tackle it yourself, or call someone?
Types of Drywall Damage (and Their Complexity)
Small holes (under 3/4")
Nail holes, small screw holes, minor dings. These are genuinely easy to DIY with a tube of lightweight spackle, a putty knife, and some sandpaper. Cost of materials: under $15.
Medium holes (3/4" to 4")
Often from doorknobs, small anchors that pulled out, or minor accidents. These require a patch — either a self-adhesive mesh patch or a California patch technique. Doable DIY for someone reasonably handy. Takes 2–3 coats of joint compound with drying time between each.
Large holes (4"+)
Requires a proper backing — either a drywall clip, wood backing, or a full stud-to-stud replacement piece. More complex to feather and blend. Matching existing texture (orange peel, knockdown, smooth) adds significant difficulty.
Water damage
Never just patch over water-damaged drywall. The source must be fixed first (always), and the damaged section removed before patching. Wet drywall can harbour mould. This is a job for a professional.
Cracks
Hairline cracks near corners or along taped seams are often structural settling — usually cosmetic but worth monitoring. Wide cracks (over 1/4") or cracks that keep coming back need proper diagnosis before patching.
The Texture Problem
This is where most DIY drywall repairs fall apart: matching the existing texture.
Toronto homes have many different textures applied over the decades:
- Smooth (newer condos, higher-end finishes) — easiest to match
- Orange peel (light spray texture) — requires a hopper gun or aerosol knockdown can
- Knockdown (heavier, random pattern) — requires a trowel and practice
- Popcorn ceiling (older homes) — contains asbestos in pre-1980 construction; do not disturb without testing
Getting the texture right requires the right tools and experience. A patch that's been perfectly filled but has the wrong texture will still be visible after painting.
DIY Drywall Repair: What You Need
For small to medium holes:
Materials:
- Lightweight joint compound (not all-purpose — it shrinks more)
- Self-adhesive mesh patch (for holes over 3/4")
- Sandpaper (120 grit, then 220 grit)
- Primer
- Matching paint (if you have it — getting a perfect paint match is its own challenge)
Tools:
- Putty knife or drywall knife (4–6" wide)
- Sanding block
- Possibly: hopper gun or aerosol texture for texture matching
Time:
- Actual work time: 30–60 minutes
- Total time: 24–48 hours (waiting for compound to dry between coats)
Professional Drywall Repair: Typical Costs in Toronto
| Job Type | Typical Cost | |---------|-------------| | Small holes (nail/screw) — per visit | $80–$120 | | Medium patch (up to 4") | $100–$180 | | Large patch (6–12") | $150–$250 | | Multiple holes (same visit) | $150–$300 | | Water damage repair (section) | $250–$500+ | | Full wall repair + texture match | $300–$600+ |
These costs include materials, labour, texture matching, and usually a prime coat. Paint matching is typically extra (or you supply the paint).
When to Call a Professional
- Holes larger than 4" in diameter
- Any water damage (fix the source first, then call for repair)
- Texture matching on anything more than a smooth finish
- Multiple repairs in the same room (painting the whole room evenly after patches)
- Cracks wider than 1/4" or recurring cracks
- Pre-sale repairs where quality needs to be high
What My Handy Guy Handles
We do drywall repair across the full range — from filling nail holes before a move-out to patching after plumbing work, to fixing doorknob holes. We bring the compound, mesh, tools, and texture gear.
We'll be honest with you: if you have a small nail hole, buy a $12 tube of spackle and do it yourself. But for anything more involved — especially where the result matters — getting it done right the first time saves the cost of a second attempt.
