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.

Is spot repair enough for my Riverdale plaster, or should the wall be skimmed?

It depends on the wall. In Riverdale, isolated cracks in sound plaster mean spot repair — widespread cracking or waves mean a full skim. We give you a straight answer for your Riverdale home.

Can you repair Riverdale 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.

Do you work on lath-and-plaster and on modern veneer plaster?

Both. Wood-lath and gypsum-lath plaster in older Riverdale homes, and veneer plaster over blueboard in newer builds. The failure modes are different, so we identify which you have before quoting.

My Riverdale plaster is bulging off the lath — fixable?

Yes. In Riverdale we re-fasten lath-separated plaster or replace what has failed, finishing with a skim-blend that hides the repair.

Plaster repair in Riverdale, blended into the original wall

As older Riverdale houses settle, the plaster tells the story: hairline cracking, lath separation bulges, crumbling around past repairs. In Riverdale we repair plaster walls and ceilings and blend the work into the surrounding surface, or skim the whole wall to a flat modern finish. Riverdale is an established south Edmonton community of 1960s-70s homes where ceiling stipple, settling cracks and dated texture are common, so plaster work here ranges from spot crack repair to full-wall resurfacing. We cover Riverdale, Boyle Street, Central McDougall, Dovercourt and Central, 7 days a week.

Gypsum lath and the middle era

Between lath and drywall

Many mid-century Riverdale homes have small gypsum board panels — often called rock lath — with a plaster skim over them, rather than wood lath.

How it fails

It fails at the panel joints rather than by losing keys, so the cracking pattern is more regular. Identifying which system you have changes both the diagnosis and the repair, so it is the first thing we look at.

Riverdale drywall in context

About Riverdale

Just east of City Hall and bounded to the south and east by the river, this large flat area is an important part of Edmonton's history.

What we see in Riverdale

In Riverdale the drywall work is infill new-build settling beside original-stock plaster/popcorn work. We confirm what your home actually needs on site, in writing, before anything starts.

Is the plaster still keyed to the lath?

The one question that sets the price

Traditional Riverdale plaster was pushed through wood lath so it squeezed out behind and hardened into keys. Those keys are all that hold it up. When they break, the plaster separates and the wall bulges or the ceiling sags.

How we check

We press and sound the surface by hand across the whole area, not only at the crack. Where the plaster still holds, it stays and gets skimmed. Where the keys have gone, that section is re-anchored with plaster washers or cut out and rebuilt. Nothing comes out that does not need to.

Why Riverdale plaster cracks in the first place

Movement, not bad workmanship

Most cracking in Riverdale 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.

Living with a heritage Riverdale interior

Mouldings and detail

Older homes often carry plaster cornice, ceiling roses and picture rails. Careless repair destroys detail that cannot easily be replaced.

How we work around it

We ask before starting what is being kept, work back to a natural break in the moulding rather than through it, and say honestly where a detail cannot be matched rather than damaging it and apologising afterwards.

Hairline crazing across a whole wall

Not the same as a crack

A network of fine random cracking across an Riverdale 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.

Reattaching plaster without removing it

Washers and adhesive

Where Riverdale plaster has separated but is otherwise sound, plaster washers screwed through into the lath or joists pull it back and hold it, sometimes with an injected adhesive behind.

Why it is worth doing

It preserves the original surface, is far less disruptive than removal, and costs less. It only works where the plaster itself is still strong, which is what the sounding test establishes.
