Can you finish over rated board so it looks like the rest of the room?

Yes. The rated joint treatment comes first because it is part of the assembly, then the visible finish is taken to whatever level suits the room. A Calder garage ceiling and a living room do not need the same finish level.

How do I know which rated assembly my Calder project needs?

It comes from your drawings or from the building official at permit stage, not from us and not from the board supplier. We build to the assembly you have been given, and if what is specified does not match what is on site we will tell you before boarding.

Do you handle the firestopping as well as the board?

We firestop the penetrations that fall within our scope and coordinate the sequence with the other trades so nothing is covered before it is sealed. Where a penetration belongs to another trade, we flag it rather than tape over it.

Where is fire-rated drywall required?

The standard Calder fire-rating locations: garage-to-house walls, basement suites and party walls between units. We confirm what your Calder project needs.

Can I put an access hatch in my rated garage ceiling?

Only with a rated detail. Any hatch interrupts the assembly. It is a common find in Calder garages where storage access was cut in afterwards and never addressed.

Fire-Rated Drywall Calder Edmonton | Type X Board

Fire-rated drywall in Calder, installed to code

A fire-rated wall is not a board, it is an assembly. In Calder that means the specified board thickness and type, the specified stud and screw spacing, taped joints, and every penetration firestopped. Miss any one of those and the rating is not there, whatever the board says on the back.

Finishing a rated wall in Calder without compromising it

Rated first, pretty second

Taping on a rated assembly in Calder does two jobs: it completes the fire separation and it produces the surface you will paint. The tape and fill on the rated joints is not optional cosmetic work.

Level of finish

Beyond the rated joint treatment, the visible finish level is your choice — a garage ceiling rarely needs the same finish as a living room. We will tell you where a higher level is worth paying for and where it is not.

Calder drywall in context

About Calder

In the early part of the 20th century, Calder was part of the Hudson's Bay Company Reserve and settled primarily by employees of the Grand Trunk Pacific Railway.

What we see in Calder

In Calder 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.

What happens when an assembly is altered later

Every future trade is a risk

A rated Calder wall or ceiling stays rated only while nobody cuts an unsealed hole in it. Later work — a fan, a light, a duct, a speaker — can quietly undo it.

What we leave you

We photograph the rated work before covering it, so there is a record of what is behind the finish for whoever works on the house next.

Sealing at the top and bottom of a rated wall

The wall has to be continuous

A rated separation that stops at a suspended ceiling, or has a gap at the floor, is not a separation. Fire and smoke go over and under it.

Deck to deck

In an Calder build the rated wall runs to the structure above and is sealed at both ends. It is the detail most often missed in conversions where a wall was built to the ceiling and no further.

What affects the cost of fire-rated drywall in Calder?

Area and assembly

The cost in Calder depends on the area and the rated assembly required — a single-layer garage ceiling is different from a two-layer party wall. The Calder rating drives the build-up, and Type X board carries a premium over standard. We price off the spec and a site look.

Passing inspection in Calder

The common rated jobs here are garages and suites. The rating only holds if the assembly is built and sealed exactly to spec, so we install it to code and seal penetrations properly so your Calder project passes the first time.

Coordinating with the electrician early

Boxes in rated walls

Outlet and switch boxes in a rated Calder assembly need treatment — spacing rules, pads or listed boxes — and back-to-back boxes are a particular problem.

Why early matters

Rearranging a box after board is up means opening a rated wall. Walking the wall with the electrician before boarding takes ten minutes and avoids that entirely.

Rated ceilings and the membrane above

Protecting the structure

A rated ceiling under living space is protecting the floor structure above it, which is why the board and its fastening are specified rather than optional.

Access hatches

Any hatch through it interrupts the assembly and needs a rated detail. It is a common find in Calder garages where storage access was cut in afterwards and never addressed.
