How much does siding replacement cost in Calgary?

The short answer

Kay2's 2026 cost guide puts a full siding replacement on an 1,800 square foot Calgary home at about $28,000 to $65,000. Vinyl sits at the low end, fibre cement such as James Hardie sits toward the top, and a tall two-storey house with lots of corners costs more than a simple bungalow of the same floor area.

Per square foot of wall, installed prices in Calgary this year run roughly like this.

The vinyl and lower fibre-cement figures come from a Calgary siding cost survey published in October 2026. Kay2's own cost guide puts installed fibre cement at $12 to $22 per square foot, with trim, corners and detailing pushing it toward the top.

Why the price per square foot is only the start

Siding is priced by the area of wall, not the floor area of the house. A two-storey house usually has more wall than its floor area suggests, and a walkout basement adds a full extra storey on one side. Then come the openings. Every window, door, vent, light and hose bib needs trim and flashing, and each one is slow, fiddly work.

So two houses with the same floor area can have very different siding bills. A simple box with eight windows is quick. A house with bump-outs, bay windows, gables and three storeys on the back is not.

How to estimate your wall area

• Measure the length of each wall and multiply by its height from the foundation to the soffit.
• For gable ends, multiply the width by the height of the triangle and divide by two.
• Add up all the walls, then take off large openings such as garage doors and big windows.
• Add around 10 per cent for waste and cuts.
• Multiply by the price per square foot for the material you are considering.

As a rough example, a house with 2,000 square feet of wall to cover in insulated vinyl at $7 to $11.50 works out to about $14,000 to $23,000 for the siding alone. Removal, repairs, trim, soffit and fascia, and permits come on top, which is why whole-house quotes end up in the range above.

What a proper siding quote should include

• Removal and disposal of the old siding, listed as its own line.
• Repairs to sheathing, with a unit price per sheet so you know what rot will cost if it is found.
• New house wrap over every wall, taped at the seams.
• New flashing over windows and doors and at the bottom of the walls.
• Corners, trim, window and door surrounds, and the capping on frames.
• Soffit and fascia, if they are being replaced too.
• Any added insulation board behind the siding.
• Scaffolding or lifts for tall walls.
• Permits, if the material is changing.
• The product warranty and the installer's workmanship warranty, in writing.

A low quote with a long list of exclusions is not a better deal. Our guide to choosing a contractor covers how to compare quotes.

What pushes the cost up

• Tall walls, such as third storeys and walkout backs, need scaffolding and take longer.
• Removing stucco costs more than removing old siding. Stucco is heavy and slow to strip, and the weight adds to disposal.
• Rot or damage behind the old siding, which nobody can see until it comes off.
• Lots of corners, gables, bump-outs and windows.
• Premium profiles such as board and batten, shakes or large panels, and dark factory colours.
• Changing the window trim to wider, heavier surrounds for a more custom look.
• Adding exterior insulation, which also means extending every window and door frame.

Vinyl, insulated vinyl or fibre cement

Builder-grade vinyl is the cheapest siding, and it is also the material most often destroyed by Calgary hail. If you choose vinyl, choose a thicker premium or insulated product. It is stiffer, quieter in the wind and holds up better to impact.

Fibre cement costs more but resists hail, fire and rot far better, and factory-painted colours last well in Calgary's strong sun. Engineered wood gives a warmer look at a price between the two. Our guide comparing stucco and siding goes through each material in detail.

Replacing siding after hail

Siding replacement in Calgary often starts with a hailstorm. The August 2024 storm alone caused nearly $2.8 billion in insured damage, and much of it was to roofs and siding.

Home insurance usually pays to repair or replace damaged siding with materials of like kind and quality, minus your deductible. If a few panels are damaged and the colour is no longer made, ask your adjuster how your policy handles matching, because policies differ. If you want to upgrade from vinyl to fibre cement, the insurer will normally pay what the vinyl would have cost and you pay the difference.

Call your insurer before any work starts, keep photos of the damage, and make sure your contractor's scope matches what the adjuster approved. Our hail-resistant exterior guide covers materials that stand up better next time.

Do you need a permit?

According to the City of Calgary, a permit is not required to replace or repair siding and trim with the same material. Replacing siding with a different siding material needs a building permit. Larger or smaller windows or doors need both a development and a building permit. Eavestroughs and downspouts do not need a permit.

Full replacement or just the damaged walls?

If only one or two walls are damaged and the product is still made, a partial replacement is often fine. Expect a slight colour difference, because the old siding has faded in the sun. Putting new siding on whole walls, rather than patches, hides the difference best.

If the colour is discontinued, the siding is near the end of its life, or you want a different look, replacing the whole house usually makes more sense. It is also the only practical moment to add insulation behind the siding and to fix the flashing around every window.

When to do it

Most siding work in Calgary happens between spring and fall. Sealants, paint and some products need temperatures above a minimum to bond and cure properly, and short winter days slow the work down. Siding can be installed in winter, but it costs more and there is less flexibility, as our guide to winter renovations explains.

Good exterior crews book up quickly after a big hail year, so plan early if your house was hit.

Adding insulation while the siding is off

When the old siding comes off, you can add rigid insulation board over the sheathing before the new siding goes on. It makes an older house warmer and quieter and cuts the cold spots at the studs. It also makes the walls thicker, so windows and doors need extended trim or new frames.

Questions people ask

• How long does siding replacement take? A typical house takes about one to three weeks of work on site, longer if there is a lot of repair underneath or the weather turns.
• Can new siding go over old siding? Sometimes over flat, sound siding, but it hides problems and makes the trim harder. In most cases it is better to strip it.
• How long does siding last? Good vinyl and fibre cement can last decades, but in Calgary hail is often what ends its life early.
• Does new siding add value? It makes a tired house look cared for, which helps when selling, but it is rarely worth more than it costs on its own.
