What to know about Energy audits
An energy audit, called an EnerGuide home evaluation when it follows Natural Resources Canada's rating system, measures how your house uses energy and where it loses heat. An energy advisor registered with NRCan inspects the house from the basement to the attic, runs a blower door test to measure airtightness and uses the results to model the home's energy use. You come away with an official rating, a label and a report that ranks the upgrades most likely to make a difference.

Energy audit costs in Mississauga
Prices depend on the details of your project. We only publish price ranges when they’re backed by real LokalMatch quote data or reliable sources. Until then, here’s what usually changes the price:
- Area to insulate: attic, walls, basement or crawl space
- Type of insulation
- Removal of old insulation
- Air sealing work
- Access to the space
- Ventilation changes
How to choose energy auditors in Mississauga
- 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 energy auditors 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?
Energy audit permits in Mississauga
Some energy audit 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.

Common energy audit questions
Is LokalMatch free for homeowners?
Yes. You never pay LokalMatch to request quotes or talk to pros. Professionals pay a fee to connect with homeowners whose projects fit their business.
How many pros will contact me?
We introduce you to a small number of relevant pros — usually no more than three — so you’re not flooded with calls. If fewer pros are available in your area, we’ll tell you instead of promising quotes we can’t deliver.
Do I have to hire someone?
No. Requesting quotes doesn’t commit you to anything. Compare your options and hire only if someone is the right fit.
