Attic Vac installs and tops up attic insulation, removes old insulation, applies spray foam, and rents a 14 HP insulation vacuum across Hamilton, from century homes in the lower city and Westdale to post-war houses on the Mountain and newer streets in Stoney Creek, Ancaster, and Waterdown.
Older homes get a material and wiring check before anything is moved, since some still have vermiculite insulation. Most post-war and newer attics only need air sealing and a top-up, which may qualify for the Ontario attic insulation rebate.

Hamilton attic assessment
Hamilton covers a wider spread of housing than almost anywhere in the region: Victorian and Edwardian homes in Durand, Kirkendall, and the lower city, 1920s and 1930s streets in Westdale, post-war bungalows and back-splits across the Mountain, and newer subdivisions in Stoney Creek, Ancaster, Binbrook, and Waterdown. The right attic scope depends on which of those you live in and what is actually above the ceiling.
Durand, Kirkendall, Corktown, and neighbouring streets often have small hatches, low roof slopes, past renovations, and several generations of insulation layered together. Access and material identity decide the scope before depth does.
Bungalows and back-splits from the 1950s to the 1970s usually have a simple, open attic that is well suited to air sealing and a blown-in top-up, as long as the existing material is dry and not contaminated.
In Stoney Creek, Ancaster, Binbrook, and Waterdown, check for thin coverage at the perimeter, blocked baffles, and settled insulation around the hatch before assuming the whole attic needs more material.
Wet, mouldy, pest-contaminated, or compressed insulation should come out. Clean, dry material that is compatible with the upgrade can usually stay, which keeps the project smaller and the cost lower.
Hamilton questions
Yes. We install and top up attic insulation, remove old insulation, apply spray foam, and rent our 14 HP insulation vacuum for homes across Hamilton, including the lower city, the Mountain, Stoney Creek, Ancaster, Dundas, Binbrook, and Waterdown.
Not automatically. What matters is what the material is, whether it is dry and clean, and whether wiring or repairs need attention first. Suspected vermiculite should be tested before anything is disturbed.
Hamilton homeowners can use the provincial Home Renovation Savings program, which offers up to $1,250 for a standalone attic insulation upgrade to R-50 with no energy assessment. The amount depends on the attic's starting R-value, and the work must be done by a participating contractor.
Yes. The 14 HP vacuum is $380 for the first day and $280 for each additional day, with bags sold separately. Pickup is available, and delivery can be arranged depending on location and schedule, so confirm it when you book.
Hamilton planning note
Older lower-city and Westdale attics are where unfamiliar loose fill is most likely. Pebble-like, grey-brown material may be vermiculite, which should be treated as potentially asbestos-containing until it has been tested. It should not be vacuumed, walked through, or covered until that question is answered.
The same older homes can still have knob-and-tube wiring in the attic. Before new insulation goes on top of any wiring of that age, have an electrician confirm what is live and what the safe approach is. It is a short conversation that prevents a much larger problem.
Once material and wiring are known, the rest is a normal plan: air seal the ceiling plane, correct ventilation and baffles at the eaves, then top up or replace the insulation to the target depth. If you are planning to claim the Ontario attic insulation rebate, the target is R-50 and the whole roof area has to be done, so confirm that in the quote.
