Blown-in cellulose is the best value for an open attic, because it reaches R-60 across the whole floor at a fraction of the cost of spray foam and flows around everything in the way. Spray foam is the answer only when the attic is a cathedral ceiling or a finished room and the roof deck itself has to be insulated. Either way the ceiling is air sealed and the eaves are baffled first.
Go to the hatch and look at the depth of the insulation. If you can see the tops of the joists, the attic is well under the recommended R-50 to R-60. Ice dams and icicles along the eaves, frost on the underside of the roof sheathing, a bedroom that is cold in January and hot in July, and a furnace that runs constantly are the other signs of thin insulation. We measure the depth at the visit and tell you what a top-up would take.
Ice dams are caused by warm air leaking into the attic and melting the snow from underneath, which refreezes at the cold eave. Insulation alone does not fix them and can hide the leak, so the fix is air sealing the ceiling, insulating to depth and keeping the soffit vents open with baffles. In a snowbelt town like Innisfil that combination is what stops them.
Yes, spray foam insulation is safe once it has cured and been covered. Foam insulation in a living space must be covered by a thermal barrier, and half-inch drywall is the standard. We measure the substrate temperature before we spray, build the thickness in lifts and keep the space clear while the foam cures and airs out. The problems people read about come from foam mixed off ratio or sprayed too cold, and we install so that does not happen.
Only when the old insulation needs to come out. Dry, clean insulation can be blown over. Wet, mouldy, burnt or animal-soiled material, and vermiculite, come out first. Removal is quoted as its own line so you can see both numbers.
Blown-in attic insulation runs about $1,800 to $3,000 for a typical 1,200 square foot attic. Closed cell spray foam in a basement runs about $4,500 to $8,000, a crawl space about $3,500 to $6,500, and batts in open framing about $1 to $2.50 a square foot. Those are Ontario market ranges, and the written price is measured on site.
Ontario's Home Renovation Savings Program has offered rebates on attic, wall and basement insulation and on air sealing for eligible homeowners, with most measures requiring a home energy assessment before and after the work and an attic-only path available without one. The amounts and rules change, so ask us at the visit and we will tell you whether it is worth applying and supply the depth measurements and photographs the application needs.
Yes, cottage insulation is one of the most common jobs we do. The crawl space is sealed and foamed first, then the walls are foamed or dense-packed, and the roof is done last, either as a cathedral ceiling in spray foam or a low attic in cellulose. We write the plan in stages so it can be done at once or over a few seasons.
Most attic insulation is air sealed and blown in one day, with removal adding a day. Basement or crawl space insulation in spray foam takes one to two days plus a day for the foam to cure and air out. Dense-packing the walls of a house takes one to two days. A cottage conversion is planned in stages and each stage is a day or two.
Yes, commercial insulation is a regular part of our work. Steel buildings get closed cell spray foam on the inside of the skin so they stop sweating, barns and drive sheds get foam with a washable coating, and the offices inside get batts. We work after hours and in sections so the business keeps running.
Each page below covers the material, where it belongs, what it costs and how long it takes in Innisfil.
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.

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.

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.
