What to know about Attic insulation
Attic insulation is often one of the most worthwhile upgrades in an older Canadian home. Heat rises, and in many houses built before today's standards the attic holds a thin, settled or patchy layer that lets warmth escape through the ceiling all winter. The same attic can turn upstairs bedrooms into ovens in summer.

How to choose insulation contractors in Welland
- Choose a contractor who talks about air sealing and ventilation, not only adding more insulation.
- Ask them to check the attic or walls for moisture, mould, old wiring or insulation that may contain asbestos before starting.
- Get a written quote that states the type of insulation, the areas covered and the target insulation level.
- For spray foam, ask about their training, curing time and when it's safe to be back in the home.
- Consider an energy audit before and after the work to see where heat is being lost.
Questions to ask insulation contractors before you hire
- What type of insulation do you recommend for this area, and why?
- Will you seal air leaks before insulating?
- How will you keep the attic properly ventilated?
- What will you do if you find old insulation that may contain asbestos, mould or old wiring?
- For spray foam, how long do we need to stay out of the house?
- Does this work need a permit or an inspection?
Attic insulation permits in Ontario
Some attic insulation work needs a permit or has to meet local bylaws. Rules vary by municipality, so ask your pro whether a permit is needed and who will apply for it — and check with your city or town if you’re unsure.
Licensing in Ontario
General contracting and renovation
Renovating an existing home generally doesn’t require an HCRA builder licence: HCRA says renovations or upgrades typically don’t make a home “new”. Ontario advises checking references, WSIB coverage and trade certificates before you hire.

What attic insulation costs in Canada
Blowing insulation into an attic is quick and cheap. Doing it in the right order is not, and the order is what decides whether you get a warmer house or a damp one.
