Step 1 of 7 · Question 1 of 1

What needs insulating? (required)

A real person responds within 24 hours.

What’s included

This is the work itself, item by item. If your job does not need one of these, it is not on your estimate.

  • Assessment before adding

    We look for air leakage and moisture first, because insulating over either makes it worse.

  • Air sealing

    Top plates, penetrations and hatches sealed, which usually does more than the insulation itself.

  • Attic insulation

    Blown or batt insulation topped up to the depth the Code requires, with baffles keeping the vents clear.

  • Wall insulation

    Cavity fill in existing walls and batt or board in open walls.

  • Spray foam

    Closed and open cell foam installed by spray-foam applicators where the assembly calls for it.

  • Basement and rim joist

    Rim joists and foundation walls insulated with the vapour control the assembly requires.

  • Crawl space insulation

    Walls or floor insulated depending on whether the crawl space is inside the envelope.

  • Ventilation check

    Attic intake and exhaust confirmed so the new insulation does not cause condensation.

  • Clean-up and depth markers

    Site cleaned and depth markers left in the attic so the work can be verified.

How it runs

Every job we take on follows the same sequence, from the first call to the walkthrough.

  1. Tell us about the house

    Age, which areas are cold, and what insulation you think is there now.

  2. We call you back

    Within 24 hours, to understand the assemblies and the symptoms.

  3. Site visit and written estimate

    We inspect the attic and the walls, and quote the scope in writing.

  4. Rebate and program check

    We tell you where the work may qualify under a current program, without promising an amount.

  5. Preparation and air sealing

    Access protected, baffles installed, and penetrations sealed.

  6. Insulation installation

    Insulation installed to the specified depth or thickness.

  7. Verification and walkthrough

    Depth checked and recorded, site cleaned, and the work shown to you.

That is the whole job. Tell us about yours and we will price it — a real person calls you back within 24 hours.
