Drywall Repair and Painting
A drywall patch succeeds when the surface is supported and the finish blends with the room, not simply when the hole is covered.
Should I Repair Plaster or Replace It With Drywall?
Direct answer
Repair is often reasonable for a localized defect where the surrounding plaster and its base remain sound. Partial drywall replacement may make more sense where material is loose, extensively damaged, repeatedly cracking or must be opened for other work. First identify the existing wall construction: an older Ottawa home may have plaster, drywall or a combination. The finished surface, thickness and transition to the retained wall matter as much as the opening size.

| Item | What to know |
|---|---|
| Small, stable defect | Assess a local plaster repair and compatible finish. |
| Loose or widespread material | Check the base and extent before choosing partial replacement. |
| Access needed behind wall | Plan opening, closure and finishing as one scope. |
Identify the wall before specifying a repair
Look at an existing opening or other safe exposed edge to establish whether this is conventional plaster on lath, veneer plaster or drywall. CGC documents these as distinct systems. Do not infer material from house age; the same home can contain later drywall repairs beside older plaster.
Map damage and its cause
Mark localized chips, cracks, hollow or loose areas and any staining. A crack that reappears or a loose base needs more than a cosmetic skim. If access to plumbing, wiring or framing is required, define that work and the closure area before promising a small patch.
Compare local repair with partial replacement
A supported local defect can be patched and blended with the existing surface. For loose or missing material, a defined section may need removal and a suitable replacement assembly. Thickness, edge support, finish texture and the transition from plaster to drywall affect the visible result; a partial replacement is not automatically invisible.
Renovation1 approach
We would photograph and probe accessible damaged edges, identify the wall system, discuss access needs and specify both substrate and finish work. Hidden conditions discovered on opening may expand the repair.
What Renovation1 does in practice
Send full-wall and raking-light photos, close-ups of cracks or loose areas and any known wall-opening history. Note whether the damage is changing.
