My Delton ceiling has a sag in it. Is that urgent?

Treat it as urgent. A sagging plaster ceiling has lost its keys and is holding itself against gravity. Keep people out from under it and call us. We will tell you whether it can be re-secured with plaster washers or has to come down.

Is it cheaper to board over the plaster instead?

Sometimes. Once roughly a third of a wall has failed, boarding over and skimming usually buys a better wall for the money than rebuilding the plaster. If the plaster is largely sound, repairing costs less and keeps the character. We quote the one we would actually do.

Can you match the texture on my old Delton walls?

Yes. We feather the skim well past the repair and match the surrounding texture before priming, so the patch does not read as a rectangle under side light. Where a wall is too uneven to blend into, we will tell you that skimming the whole wall gives a better result.

Do you work on plaster over brick?

Yes, and it is a different substrate — no lath, no keys, bonded to the masonry. It fails where damp has reached the brick, so we look for the moisture source before quoting, or the problem just moves along the wall.

Will you damage my plaster mouldings?

Not knowingly. We ask what is being kept before starting and work back to a natural break in the moulding rather than through it. Where a detail cannot be matched we say so beforehand rather than apologising after.

Can you repair Delton plaster without tearing the wall out?

In most cases, yes. If the plaster is still keyed to the lath it gets re-anchored and skimmed rather than removed. We only cut out sections that have genuinely failed, and we tell you on site which of the two you have.

Plaster repair in Delton, blended into the original wall

As older Delton houses settle, the plaster tells the story: hairline cracking, lath separation bulges, crumbling around past repairs. In Delton we repair plaster walls and ceilings and blend the work into the surrounding surface, or skim the whole wall to a flat modern finish. Delton is this established North Central community where reno, repair and ceiling drywall are common, so plaster work here ranges from spot crack repair to full-wall resurfacing. We cover Delton, Abbottsfield, Alberta Avenue, Beacon Heights and North Central, 7 days a week.

Our Delton plaster repair process in Edmonton, step by step

Stabilise the plaster first

A plaster repair in Delton only lasts if the plaster is stable. Pulled-away Delton plaster gets re-anchored; crumbling sections get cut back to sound material first. That skipped step is why Delton plaster patches so often re-crack.

Patch, skim, blend

The right plaster-grade material goes in, the area or full wall gets skimmed flat, edges feathered wide, then sanded paint-ready. In most Delton homes, once it is painted you will not find where we worked.

Delton drywall in context

About Delton

Delton has been part of Edmonton since 1910, a time when land speculators fuelled a tremendous expansion in the supply of vacant subdivisions.

What we see in Delton

In Delton the drywall work is plaster and lath repair, popcorn and stipple ceiling removal, careful patching into original surfaces. We confirm what your home actually needs on site, in writing, before anything starts.

Living in the house while Delton plaster is repaired

Dust is the real disruption

Plaster repair makes fine dust that travels, so containment matters more here than on new work. We seal the working area, cover floors, and run the sanding to a vacuum where the job allows it.

Sequencing around you

Plaster repairs cure in coats, so a room is usually worked over several visits rather than one long day. We sequence so the space is usable between coats wherever possible, and we say up front which days it genuinely will not be.

Corner beads in plaster walls

Metal that rusts

Older Delton plaster corners often have metal bead beneath, and where moisture has reached it the rust expands and pushes the plaster off from behind.

Why filling fails

Filling that corner without dealing with the corroded bead means the same failure returns, because the cause is still expanding. The bead section comes out and is replaced.

Why Delton plaster cracks in the first place

Movement, not bad workmanship

Most cracking in Delton plaster is seasonal movement rather than a defect. Alberta humidity swings move a timber frame, and plaster is rigid, so it relieves that stress at its weakest points: the corners of door and window openings, and the joint between ceiling and wall.

What that means for the repair

A crack that moves has to be taped, not just filled. Filler on its own bridges the gap and re-cracks in the first dry spell. We tape across the crack so the repair can take the movement, then skim it out flat.

Skim coating over sound Delton plaster

When a whole-wall skim beats patching

Where a Delton wall carries dozens of small repairs, decades of paint build-up and an uneven surface, patching each mark leaves a wall that still looks patched. A full skim coat over the sound plaster resets the surface to one flat plane.

What is involved

The wall is stabilised, glossy or flaking paint is de-glossed or removed, a bonding agent goes on where it is needed, then two thin coats are trowelled and sanded. The result takes paint like new board while keeping the original wall behind it.

Hairline crazing across a whole wall

Not the same as a crack

A network of fine random cracking across an Delton plaster surface is usually shrinkage in the finish coat or a paint film failing, not structural movement.

What it needs

Not filling — that leaves a wall of filled lines. It needs the surface stabilised and skimmed as a whole, which is why it is priced by the wall rather than by the crack.
