Why Ajax attics differ from street to street
Ajax began as a wartime industrial town. In 1941 the federal government built the Defence Industries Limited (DIL) shell-filling plant in what is now south Ajax, and Wartime Housing Limited put up prefabricated houses for workers that were meant to be temporary. After the war, CMHC-era subdivisions followed. Ajax became a town in 1954, and in 1974 its boundaries grew to take in Pickering Village, Pickering Beach and Audley (History of Ajax, McGeachy, Ontario History, 2006). Later decades added large subdivisions further north. That history gives Ajax a wide mix of attics:
- Wartime and early postwar homes in south Ajax: small, low attics with tight access, little ventilation and often thin or mixed old insulation. These need careful assessment, and any old loose-fill is identified before it’s disturbed.
- Older homes in and around Pickering Village: a range of ages, often with several rounds of renovation and layers of different insulation overhead.
- 1960s–1980s homes: insulation has often settled, and past roof leaks or fans venting into the attic can leave damp or stained material.
- Newer north Ajax subdivisions: generally better insulated when built, but settling, thin spots at the eaves and wind-washed insulation are common as homes age. A top-up is often enough.
Our attic insulation process in Ajax
- Get a quote. Call 647-453-7037 or email us, and send your address, attic details or a few photos. If you plan to use the attic rebate, register with the program first. For some homes, depending on age and construction, we do a quick site check before the job so there are no surprises.
- Clear recommendation. We explain whether to top up or remove and why, and give you an itemized quote with the finished R-value stated. When we see the attic — from your photos, or in person if a site check is needed — we look at insulation depth, moisture, mould on the sheathing, rodent activity, air leaks and blocked soffits.
- Removal (if needed). Old insulation is vacuumed out and bagged, and the attic floor is cleaned so the deck and framing can be checked.
- Air sealing and ventilation. Gaps and penetrations in the ceiling are sealed, baffles go in at the eaves, and fans venting into the attic are corrected.
- Re-insulate. New blown-in insulation is installed evenly to R-50 or more, and depth is checked across the attic.
- Paperwork. For rebate jobs, you receive the invoice and documents the program asks for.
Remove or top up?
- Top up when the existing insulation is dry, clean and fairly even. It’s the lower-cost path.
- Remove when the old material is wet, mould is on the sheathing, rodents have nested in it, or it has packed down so thin the ceiling shows through in spots.
- Stop and test if we find vermiculite, a pebbly grey-brown or gold loose-fill. It may contain asbestos, and Health Canada advises leaving it undisturbed and hiring a qualified asbestos professional if it has to come out.

Attic insulation rebate for Ajax homeowners
The attic stream of the Home Renovation Savings program, run by Enbridge Gas and Save on Energy, doesn’t require a home energy assessment. According to the official program page, the rebate is 50% of the after-tax insulation cost, up to a maximum based on the attic’s starting insulation level:
- R-12 or less: up to $1,250
- Above R-12 to R-25: up to $1,000
- Above R-25 to R-35: up to $800
The finished attic must reach at least R-50, and the whole roof assembly must be insulated. You must own the home, which must be a detached, semi-detached, row/townhome or mobile home on a permanent foundation. Stacked townhomes and new builds don’t qualify. You must also heat with Enbridge natural gas, or with electricity, oil, propane or wood while connected to the Ontario grid. The work must be done by a participating contractor, and a home that already received an attic insulation rebate from Enbridge or Save on Energy isn’t eligible again. The starting insulation level is recorded before any old insulation comes out. The program describes the rebate as covering the purchase and installation of insulation, so we list removal and clean-up work separately on quotes.
Enbridge Gas announced in October 2026 that the program has been extended to March 31, 2027. Confirm current dates and eligibility at homerenovationsavings.ca before booking, because the official terms may still show the earlier date. Our Ontario attic insulation rebate guide walks through each step. Be wary of door-knockers or callers who claim to be from Enbridge.

How do I know if my Ajax attic insulation needs to be removed or just topped up?
If the insulation is dry, clean and even, a top-up is usually enough. If it’s wet, mouldy, contaminated by rodents or badly compressed, it should come out first. We’ll recommend one or the other after we see the attic — usually from your photos, or in person if a site check is needed.
Can you remove rodent-contaminated or mouldy attic insulation in Ajax?
Yes. We vacuum out contaminated insulation, check the roof deck and framing once the floor is clear, air-seal, and then re-insulate. If mould is on the roof sheathing or the source of the moisture needs fixing, we explain that before re-insulating.
Can Ajax homeowners get a rebate for attic insulation?
Eligible homeowners can get 50% of the after-tax insulation cost back through the Home Renovation Savings attic stream, up to $1,250, $1,000 or $800 depending on the starting insulation level, when the attic is brought to at least R-50 by a participating contractor. Enbridge Gas announced in October 2026 that the program has been extended to March 31, 2027. Confirm current dates and eligibility at homerenovationsavings.ca, because the official terms may still show the earlier date.
Does the rebate cover removing old insulation?
The program describes the rebate as covering the purchase and installation of insulation. Removal and clean-up aren’t listed, so we show them as separate lines on your quote.
How much does attic insulation cost in Ajax?
It depends on attic size, how much insulation is there now, whether removal is needed and how much air sealing is required. Send us a few details or photos and we’ll give you a free, itemized quote.
Do you serve older homes in south Ajax and Pickering Village?
Yes. Older and wartime-era homes often have small, low attics, so we check access, ventilation and the type of old insulation before recommending the safest way to bring them up to R-50 or more.
