Our services

A clear price for every project in your home.

Each example is calculated with the same pricing grids as your quote. Your price follows your house: its size, its year and your answers.

  • Attic insulation

    Adding or replacing attic insulation, ventilation and air sealing: the price comes from your address and a few details about the attic.

    Example · House built in 1985, 1,100 sq ft attic

    $3,300 to $3,850before taxes

    • Blown-in insulation, R-60 or more after settling
    • Cleared ventilation and baffles
  • Roofing

    Full replacement, from tear-off to new shingles: the roof is measured on the satellite photo, slope included.

    Example · 1,200 sq ft asphalt shingle roof, medium slope

    $6,850 to $7,900before taxes

    • Tear-off, dumpster and yard clean-up
    • 128 sq ft of damaged plywood replaced, included
  • Doors and windows

    Replacement, sealed glass units (thermos) or caulking: take photos of your windows, or let us count them based on the size of the house on the municipal assessment roll.

    Example · 9 windows in standard sizes, on the ground floor, with vinyl or wood siding

    $8,550 to $10,500before taxes

    • White PVC with double glazing
    • Removal of the old ones, installation, insulation around the frame and finishing

Transparency

What makes the price vary.

Two houses of the same size can cost very different amounts. Our questions help us understand yours, so that the quote truly reflects your house.

The firm price is confirmed on site, never before. You know exactly what you are paying.

  • The size of the attic

    This is what matters most. Operos measures it on the satellite photo, from your address.

  • The insulation already in place

    Insulation that is packed down, damp or old sometimes has to be removed before more is added. The year built, listed on the municipal assessment roll, gives a good clue.

  • Access to the attic

    A small attic hatch in a closet takes more time than an easy-to-reach door.

  • Ventilation and mould

    Black stains on the wood often mean the ventilation needs to be fixed at the same time.

How it works

Three simple steps, from the first click to the price.

  1. 1

    Choose your project

    Attic insulation, roofing, and doors and windows: just one click to get started.

  2. 2

    Enter your address

    Operos finds the year and size of the house on the municipal assessment roll, and measures the roof on the satellite photo. No tape measure needed, and “I don't know” is always a good answer.

  3. 3

    See your price right away

    Your price range and the details of the work appear on screen, and you receive the PDF by email. An expert then confirms the firm price with you.

Several projects

The whole house, without retyping anything.

After your first quote, add another project for the same house. Your address and contact details are carried over: only the questions specific to the work remain. Each quote arrives separately, with no obligation.

Insulation · why insulate

An investment you feel every day.

More comfortable

No more upstairs that's too hot in summer and cold rooms in winter. The temperature becomes more even from one room to the next.

Less heat lost

Heat rises. A well-insulated attic keeps it in the house instead of letting it escape through the roof.

A protected roof

Less heat in the attic means fewer icicles along the edge of the roof and less moisture on the wood.

Self-check

Your attic may be sending you signs.

Check what you notice at home. It takes ten seconds and tells you whether an evaluation is worth it.

Up to $2,000 in grants

Rénoclimat, with no energy evaluation needed since October 1, or Hydro-Québec's LogisVert. Your quote calculates the amount for you.

Frequently asked questions

You may be wondering…

What is Operos?

Operos is your renovation assistant in Québec: it shows you the price of your project online, free and with no obligation. For attic insulation, roofing, and doors and windows, enter your address and your price appears in 2 minutes. Coming soon: air conditioning and heating.

Is it really free?

Yes. The online estimate and the inspection are free, with no obligation. You decide afterwards, with no pressure.

How is my house measured?

From your address: your municipality's assessment roll gives the year and size of the house, and the satellite photo measures the roof. You have nothing to measure. Any detail that needs correcting can be changed on the quote.

I have several projects. Do I have to start over?

No. After your first quote, add another project for the same house: your address and contact details are carried over, and only the questions specific to the work remain. Each quote arrives separately, with no obligation.

How long does it take?

About 2 minutes online. You can stop partway and pick up later on the same device.

Do I see a price right away?

Yes. At the end, you see a price range and the details of the proposed work, and you receive it all as a PDF by email. An expert then confirms the firm price on site, so there are no unpleasant surprises.

Where do your prices come from?

From real data. Our insulation and asphalt shingle roofing price grids are built from data we collected ourselves on thousands of renovation transactions carried out across different areas of Québec. Our doors and windows grid starts from Québec's public price guides. Each grid is the same everywhere in Québec, whatever the contractor. The method is explained in our price barometer (in French).

I don't know what year my house was built. Is that a problem?

Not at all. Choose “I don't know” and you'll still see your price.

Who will do the work?

A contractor in your area who partners with Operos. Before passing on a request, Operos checks that they hold a valid licence from the Régie du bâtiment du Québec (RBQ). You can also check their licence number yourself in the RBQ's public register.

What do you do with my information?

It is used only to prepare your quote. It is shared only with the partner contractor handling your request, with your consent, as required by Law 25.

Which project would you like priced?

Two minutes now, a clear price to decide with peace of mind.
