Insulation Rebates in Manitoba: How to Use Them During a Renovation

A renovation is often the easiest time to add insulation. The basement is bare studs, the walls are open, or the old siding is coming off anyway. In Manitoba, the main program that helps with the cost of the insulation itself is Efficiency Manitoba's Home Insulation Rebate. The catch is timing: the rebate is approved before work starts, so it has to be part of the plan from the first conversation, not something you remember once the old drywall is in the bin.

Everything below was checked against the official program pages on October 13, 2026. Programs change, so confirm the details with Efficiency Manitoba before you sign a contract.

Can you get an insulation rebate during a renovation?

Yes, if the area qualifies and the application is approved before work begins. Efficiency Manitoba's Home Insulation Rebate covers attics, roofs, wall cavities, exterior walls during re-siding, and foundation walls and joist headers. Projects that have already started or are finished are not eligible, so the rebate has to be lined up while you are still planning.

The program page lists these basics:

• You own the home, rental property or cottage, it has active Manitoba Hydro residential service, and it is heated for the whole heating season, September to May.
• The home is detached, semi-detached, or a mobile or modular home on a permanent foundation with a permanent water supply.
• Each area is at least 100 square feet (joist headers are the exception), and you have not already received a rebate for that area.
• Garages, three-season sunrooms, porches, verandas, seasonal homes, apartments and converting unheated space to heated space are not eligible.

How much does the rebate pay for each area?

The rebate is a set rate multiplied by the R-value you add and the square footage you insulate. Each area must start at or below a set R-value and finish within a required range. The rebate for an area cannot be more than the cost of the insulation material needed to reach that range, taxes included.

Source: Efficiency Manitoba. Insulation beyond the required final level is not rebated, and when old insulation is replaced only the R-value added above the original level counts.

To see how the arithmetic works: taking 600 square feet of uninsulated foundation wall to R-24 adds 24 R-value points, so the calculation is $0.06 × 24 × 600, or $864, as long as that does not exceed the cost of the insulation material. Your actual rebate depends on the measured areas and the existing R-values Efficiency Manitoba accepts.

Why does approval have to come before demolition?

Because Efficiency Manitoba needs to see what is there before it changes. Approval must come before you buy materials or start any work, including removing drywall, stucco or original insulation, and your home may be selected for an inspection to check the existing R-values and measure the area. Once a wall is gutted, there is nothing left to verify.

This is the step that catches people out on renovations, because a basement development or a kitchen gut usually starts with demolition. Build the rebate into the schedule like this:

1. Decide which areas you want insulated, such as foundation walls, the attic or exterior walls during re-siding, before the scope is final.
2. Choose a registered contractor or retailer from Efficiency Manitoba's supplier directory. The supplier starts the application, and the materials must be bought from the supplier named on it.
3. Wait for approval, including a pre-verification inspection if your home is selected.
4. Do the work: demolition, any air sealing, then the insulation, which must be installed within 12 months of the approval date.
5. Once the insulation is installed and paid for, your registered supplier starts the completion process, or you can contact Efficiency Manitoba; keep every receipt and invoice. A post-verification inspection may be needed before the cheque is mailed.

How does the air sealing bonus work?

Efficiency Manitoba adds an air sealing bonus of up to $1,000 to the insulation rebate. A pre-retrofit EnerGuide evaluation is the required first step, the air sealing must be done before the insulation goes in, and a post-retrofit evaluation measures the change in air leakage. Both evaluation reports are submitted with your paperwork.

Separately, Efficiency Manitoba offers a $400 rebate for a pre-retrofit EnerGuide evaluation when you plan at least one energy efficiency upgrade within the next 12 months; apply within 90 days of the evaluation. On a large renovation, booking the evaluation early gives you a baseline and keeps the air sealing bonus open.

Which programs are open, and which are closed?

As of October 13, 2026, Efficiency Manitoba's insulation rebate and Manitoba Hydro's Home Energy Efficiency Loan are both presented as current offers on their official pages. The federal Canada Greener Homes Grant and Canada Greener Homes Loan are closed, so do not build a renovation budget around either one.

Each program's official page is listed under Sources. Check them again before you rely on any of these.

Manitoba Hydro's Home Energy Efficiency Loan can finance insulation, with payments added to your energy bill. Manitoba Hydro must approve the application before any work starts or materials are bought, and the loan becomes due when the house is sold. Households that meet income requirements may qualify for free insulation upgrades through Efficiency Manitoba's Energy Efficiency Assistance Program, and there are separate First Nation and Métis offers.

Where does insulation fit in a basement or whole-home renovation?

Insulation goes in after framing and the plumbing and electrical rough-in, and before drywall. In a basement development that usually means the foundation walls and joist headers; in a whole-home renovation it can also mean exterior walls opened from inside and the attic. Any moisture problem should be fixed before insulation covers a wall.

A few practical points from the planning stage:

• A basement development needs a building permit from the City of Winnipeg. We coordinate permits and inspections with the City, or with your local municipality outside Winnipeg, as part of a basement development.
• If the basement has a history of water, deal with that first. Our guide to protecting a Winnipeg basement from flooding covers where to start.
• If the attic or walls contain loose, pebble-like vermiculite insulation, Health Canada advises not disturbing it and having a professional test for asbestos before renovating, with removal by a qualified specialist if it is found.
• On a whole home renovation, list every area you might insulate before the rebate application goes in, because each area is approved on its own.

What to ask at the on-site visit

• Which areas of my house are likely to meet the starting R-value limits?
• Who is the registered supplier on the rebate application, and when will approval come relative to demolition?
• Is air sealing part of the scope, and is the EnerGuide bonus worth it for my house?
• How does the 12-month installation window fit the construction schedule?
