How much does new exterior siding cost in Quebec in 2026?
Replacing a home's exterior siding in Quebec costs from $5 per sq ft of wall for vinyl to over $40 for brick, installed and before taxes. For a house with about 1,800 sq ft of walls, the budget ranges from roughly $9,000 to more than $80,000. Tear-off, the air barrier and trim around openings weigh heavily on the bill.

What drives the price
- Tearing off and disposing of the old siding, especially when there are several layers.
- The air barrier membrane and furring, which protect walls from water and condensation.
- The number of windows, doors and corners that need trim and flashing.
- The height of the house and the scaffolding required.
- Brick and stone, which need a foundation ledge or angle iron able to carry their weight.
Mistakes to avoid
- Installing new siding without checking the wood and insulation behind the old one.
- Forgetting flashing above windows and doors, the leading cause of water infiltration.
- Choosing a material without checking municipal or heritage-area appearance rules.
- Replacing windows after the siding: the two should be coordinated to avoid redoing the trim.
How to get reliable quotes
- Ask for the wall area the contractor calculated and how openings are deducted.
- Have tear-off, the dumpster, the air barrier and soffits confirmed as included or not.
- Compare the manufacturer's warranty with the contractor's installation warranty.
- Check that the contractor holds a valid RBQ licence for this type of work in the Régie du bâtiment du Québec registry.
- Insist on a detailed written quote and compare at least three quotes line by line, not just the total.

Frequently asked questions
What is the cheapest exterior siding?
Vinyl remains the most affordable, often $5 to $10 per sq ft of wall installed. It needs little upkeep but handles impacts less well than other materials.
Do I need a permit to change my siding?
Most municipalities require a permit or approval, especially if the material or colour changes. Some areas have appearance rules.
How long does installation take?
For a single-family home, usually one to three weeks depending on the material and weather.
Can two materials be combined?
Yes, for example stone on the front and vinyl or engineered wood on the sides. It is a common way to control the budget.
