Can you repair plaster instead of replacing it?

Yes — where the plaster is sound enough, we repair cracks, fill holes and re-secure sections that have pulled from the lath, then blend the repair in. We repair before replacing whenever the plaster can be saved.

Can you fix plaster that is sagging or pulling away from the wall?

Yes. We re-secure plaster that has pulled from the lath, and where a section has failed we re-back and rebuild it, then skim and blend the surface.

Do you repair water-damaged plaster?

Yes — once the source is addressed and the area is dry, we repair or rebuild the damaged plaster and blend it in. We can provide photos and invoices for an insurance claim where relevant.

Can you blend a plaster repair into the existing wall?

Yes. Blending the repair so it disappears into the surrounding plaster is the skilled finishing part of the job, and it is our specialty as a finishing company.

Do you handle plaster-to-drywall transitions?

Yes — in renovations where new drywall meets old plaster, we make the transition cleanly so the two surfaces read as one flat wall.

Do you cover all of Calgary for plaster repair?

Yes — all four Calgary quadrants, Airdrie, Cochrane, Okotoks and surrounding communities, 7 days a week, excluding downtown high-rise towers.

Plaster repair that respects an older home

Older and character homes in Calgary often have lath-and-plaster walls and ceilings, and plaster behaves differently from modern drywall — it cracks along stress lines, can pull away from the lath, and needs the right approach to repair without making things worse. We repair plaster cracks, holes, sagging sections and water damage, re-bond or re-back where the plaster has let go, and blend the repair into the surrounding surface so it disappears. We respect how an older home is built rather than just ripping it out. We cover all four Calgary quadrants, Airdrie, Cochrane and Okotoks, 7 days a week.

What affects the cost of plaster repair in Calgary?

Type and extent of damage

Plaster repair cost in Calgary depends on whether it is a hairline crack, a hole, a section that has pulled away from the lath, or water-damaged plaster that needs backing replaced. A surface crack is quick; re-securing sagging plaster or rebuilding a failed section is more involved. We assess on site and give a fixed price before we start.

Repair vs skim vs partial replacement

Sometimes the best value is to repair and blend; sometimes it is to skim a tired plaster wall flat; and where plaster has truly failed, a partial drywall replacement that ties into the plaster is the right call. We give you an honest recommendation for your wall.

Matching an older finish

Blending a repair into an old plaster surface so it disappears takes skill and time, and that finishing is part of the job. We finish so the repair reads as part of the original wall.

Our Calgary plaster repair process, step by step

Find why the plaster failed

Plaster cracks and sags for reasons — settling, vibration, moisture, or the plaster keys breaking off the lath behind it. We identify the cause first, because a repair that ignores it will fail again. Water-damaged plaster, for example, needs the source addressed and the area dried before repair.

Re-secure, fill and re-back

Where plaster has pulled from the lath, we re-secure it; where a section has failed, we re-back and rebuild it. Cracks are opened, bridged and filled so they do not telegraph back through. We use methods suited to plaster, not just drywall compound slapped over the top.

Skim, blend and finish

We skim and feather the repair into the surrounding plaster, sand smooth and check under light so the repaired area blends with the original wall. The goal is a wall where you cannot tell a repair happened.

Plaster versus drywall repair

Why plaster is different

Plaster is a harder, more brittle surface bonded to lath, and it cracks and fails differently from modern drywall. Treating plaster like drywall — just filling and sanding — often leads to cracks returning or repairs that do not bond. We approach plaster on its own terms.

Plaster-to-drywall transitions

In many older Calgary homes, renovations mean new drywall meeting old plaster. We make that transition cleanly so the two surfaces read as one flat wall. For modern drywall repairs specifically, see our drywall repair page; to smooth a tired plaster wall, see skim coating.

Plaster repair work we do across Calgary

Older and character communities

Lath-and-plaster is most common in Calgary's older and inner-city communities — Bowness, Silver Springs, Killarney, Renfrew, Bridgeland and the established inner ring — so that is where most plaster repair work is. We repair cracks, holes and sagging in these character homes while respecting how they are built.

Renovations and water events

Plaster repair often comes up during renovations of older homes, and after water events that stained or softened plaster ceilings and walls. We repair the plaster, blend it in, and can provide photos and invoices for an insurance claim where relevant.

Respecting an older home

Repair before replace

Original plaster is part of what gives an older Calgary home its character and solidity. Where it can be repaired and re-secured, that is usually better than tearing it out — it preserves the home and is often less disruptive. We repair before we replace whenever the plaster is sound enough to save.

When replacement is the right call

Where plaster has comprehensively failed or is unsafe, a clean partial drywall replacement that ties into the surrounding plaster is the honest recommendation. We tell you which path makes sense rather than defaulting to demolition.
