Wall insulation is how we fill the empty or under-filled exterior walls of an existing house without stripping the drywall, and how we fill the open walls of an addition or new build. Dense-pack cellulose goes into closed walls through small holes, and netted cellulose, batts or spray foam go into open ones. We carry full insurance on every job.
The written scope names the material, the wall area and the method before we start.
Many houses in Innisfil built before the 1970s have nothing at all in their exterior walls, and many built after have batts that have slumped or were never fitted properly. The farmhouses on the concessions around Churchill and Stroud, the older streets of Cookstown, and the original cottages along the shore all fall into that group. A thermal camera on a cold morning shows the empty bays as bright stripes, and we use one at the visit.
Dense-pack cellulose is what goes into a finished wall, because it fills the whole cavity at a density that cannot settle and it goes in through a hole the size of a coffee cup in each stud bay. The holes are drilled from outside under the siding or from inside through the drywall, the cellulose is packed with a fill tube, and the holes are plugged and patched. The blown-in insulation page explains the material.
On a brick or solid masonry wall with no cavity, there is nothing to fill, and we say so rather than drill holes that go nowhere.
Open framing on an addition, a gutted renovation or a new house gives us the choice of netted cellulose, batts or spray foam, and we recommend by the wall. Netted cellulose fills around wiring and boxes best and quiets the wall. Batts are the least expensive and suit a simple wall, as the batt insulation page explains. Closed cell spray foam is the answer where the wall also has to be the air and vapour barrier, such as a lakefront wall facing the wind off Kempenfelt Bay.
Filling the walls does the most good when the top plates are sealed from the attic side at the same time, because that joint is where the warm air that used to rise up the empty wall leaks out into the attic. The air sealing and attic ventilation page describes it, and we usually price the two together.
Dense-packing walls in Innisfil is priced by the wall and typically runs about $2 to $4 a square foot of wall area, depending on whether the holes go through siding or drywall and how much patching follows. Open-wall batts run about $1 to $2.50 a square foot and spray foam about $3 to $8.50 depending on type and thickness. Those are Ontario market ranges, and the written price follows the site visit. Ontario's Home Renovation Savings Program has offered a rebate on exterior wall insulation.
Call +1 705-805-8881 or fill in the form below with the age of the house and the type of siding. We come out with the thermal camera, find the empty bays and write the price down. The full list of services is on the Innisfil Insulation Services home page.
The visit and the written scope are the same for every service, so pick the part of the building that needs attention.
Attic insulation is the service we install most often, because the attic is where a house loses the largest share of its heat and where a top-up returns the most for the money. We air seal the ceiling, fit baffles at the eaves and blow cellulose to the recommended depth, and every job is fully insured.

Spray foam insulation is the material we install where air, moisture and heat all have to be stopped in one layer, which in Innisfil means rim joists, crawl spaces, foundation walls, cathedral ceilings and steel buildings. Closed cell and open cell foam are both available, the substrate is measured before anything is sprayed, and the work is insured.

Blown-in cellulose or fiberglass is loose fill delivered through a hose, and it is how we insulate most Innisfil attics, fill the empty walls of older houses and pack the cavities of new builds. It reaches any depth you ask for, flows around obstacles that batts cannot, and costs far less than foam over the same area. We carry full insurance on every job.

Batts are fiberglass or mineral wool cut to fit between studs and joists, and they are the simple choice for open framing in a basement, a garage, an addition or a new build. Batts are inexpensive, they go in quickly, and fitted properly they perform to their rating. The work is insured.

Insulation removal is the vacuuming or bagging of old attic, wall and crawl space material that is wet, soiled by animals, mouldy, burnt, failed or simply in the way of a renovation, and we do it as its own service or as the first step of a new install. The material is taken away and the framing is cleaned before anything new goes in. Insurance covers the work.

Basement insulation covers the foundation walls, the rim joist and, where it helps, the ceiling of a lower level, and it is the cure for cold floors on the main level of a house. We install closed cell spray foam directly on the concrete or batts in a framed wall depending on the basement, and the rim joist is foamed either way. The work is fully insured.

Crawl space insulation is the work that makes the floors of a shallow-foundation house or cottage warm, and Innisfil has more crawl spaces than most Ontario towns because of the lakeshore building stock. We seal the ground, insulate the walls or the floor above with closed cell spray foam, and turn a vented crawl space into a sealed one. All of our work is fully insured.

Garage insulation covers the walls and ceiling of an attached garage, the ceiling under a bonus room, and detached garages and workshops that are heated, and it is one of the most common calls we get from the newer subdivisions. We install batts, mineral wool or spray foam depending on the assembly, and every job is fully insured.

Soundproofing insulation is mineral wool or dense-pack cellulose installed inside interior walls, floors and ceilings to keep the noise of one room out of the next, and it goes into renovations, new builds and finished basements across Innisfil. It goes in while the framing is open or through small holes in a finished wall, and insurance covers the work.

Air sealing and attic ventilation are the two pieces of work that decide whether attic insulation performs, and in Innisfil they are also the cure for ice dams. We seal the ceiling from the attic side, insulate and seal the hatch, and fit baffles at the eaves so the soffit vents keep working above the new depth. We carry full insurance on every job.

Cottage insulation is the work of bringing a seasonal building along the Lake Simcoe shore up to a standard it can be lived in through an Innisfil winter, from the crawl space to the roof, and it is a job this town has more of than almost any other. We plan it in stages that match a budget and a season, and every stage is fully insured.

Commercial insulation in Innisfil covers the steel and block buildings at Innisfil Heights along Highway 400, the shops and retail space along Innisfil Beach Road and in Cookstown, and the barns, drive sheds and workshops on the surrounding farms. We install spray foam, batts and blown-in insulation to suit the building and schedule the work around the business. Every job is fully insured.
