Attic, wall and basement insulation in Oshawa

Local attic, wall and basement insulation for homes in Oshawa — assessed for your building's actual needs, with a clear estimate before we start.

Oshawa's housing stock includes a large number of post-war homes built in the 1950s and 60s across neighbourhoods like McLaughlin, Eastdale and Vanier, many of which are still running on original attic insulation. As more homeowners move to Oshawa from elsewhere in the GTA, we're seeing more requests for attic top-ups, wall insulation in renovated homes, and basement insulation ahead of finishing. We serve Oshawa and the surrounding Durham Region with straightforward, honest estimates — you'll know exactly what your home needs and what it costs before we start.

Attic

Attic Insulation

The attic accounts for a large share of a home's heat loss. We install blown-in or batt insulation based on your roof's configuration, with a vapor barrier and proper ventilation to prevent ice damming and mold.

  • Blown-in insulation (cellulose or fiberglass)
  • Topping up existing insulation
  • Vapor barrier and baffle installation
  • Correcting thermal bridging and air leaks
New Build & Renovation

Wall Insulation

Whether it's new construction or a renovation project, we insulate your exterior walls with the material best suited to your budget and energy performance goals, including spray foam for superior air sealing.

  • Mineral wool or fiberglass batt
  • Spray foam insulation (high performance)
  • Insulation for additions and renovations
  • Improved air sealing
Comfort & Moisture Control

Basement Insulation

A poorly insulated basement lets heat escape and invites moisture. We insulate foundation walls and slabs to create a comfortable, dry space that's ready to be finished.

  • Foundation wall insulation
  • Slab insulation and thermal break
  • Moisture management and vapor barrier
  • Preparation for basement finishing
Decontamination

Attic Decontamination

A contaminated attic (mold, rodent droppings, vermiculite) needs to be decontaminated before any new insulation goes in. We safely remove the contaminated insulation, clean the space and prepare it for compliant re-insulation.

  • Removal of contaminated insulation (mold, rodent droppings)
  • Safe handling of vermiculite
  • Cleaning and preparation of the attic
  • Complete re-insulation after decontamination
