Rénoclimat: Quebec's rebate for better home insulation

Rénoclimat is the provincial program that funds energy efficiency upgrades for existing homes: mainly insulation, air sealing, and the replacement of doors and windows. Managed by the Quebec government, it relies on an EnerGuide assessment before and after the work to measure the actual improvement. It is currently the central program for homeowners looking to upgrade the envelope of their home in Quebec, and it stacks well with other rebates.

Who qualifies

Rénoclimat targets owners of existing residential homes in Quebec. Single-family homes are the main focus, but smaller multi-unit buildings also qualify through the residential stream. New construction is not covered: Rénoclimat is designed to improve existing homes, not build them.

The homeowner needs an active residential energy account in the name of the home. For condo units, each owner can usually apply separately for their share, which simplifies collective envelope projects. The renovation contractor doing the work does not need to be Rénoclimat-certified themselves, but they must respect the program's technical requirements (insulation types, eligible ENERGY STAR windows, installation methods).

How to apply

The procedure follows a five-step sequence, and the first step is non-negotiable.

1. Book an EnerGuide pre-assessment with a certified energy advisor. The pre-assessment includes a blower door airtightness test, a visual inspection of existing insulation, and a detailed report with prioritized recommendations. It serves as the baseline for calculating the final rebate.
2. Complete the recommended work. The work can be done in stages or all in one phase, as long as it is finished before the post-assessment.
3. Book the EnerGuide post-assessment once the work is done. The advisor returns to measure the actual gains (usually a second blower door test) and compares them with the initial report.
4. The advisor submits the results to Rénoclimat. The final amount is calculated based on the measured improvement, not on the cost of the work.
5. Receive the payment by cheque or bank transfer within the following weeks.

What work is covered

Rénoclimat covers four main categories of envelope work.

Insulation is the main stream: attic insulation (the most cost-effective project in an existing home), above-grade walls, basements, and exposed floors over unheated spaces (garage, crawl space). The eligible insulation types are defined by the program and include cellulose, mineral wool, rigid foam panels, and a few others.

Air sealing targets all parasitic infiltration: caulking around existing windows and doors, perimeter sealing, and sealing of electrical and plumbing penetrations. This work is often inexpensive and has a high measured impact at the blower door.

Window and door replacement with ENERGY STAR-eligible models is covered, provided the installed models appear on the list recognized by the program. A high-performance triple-pane window can make a real difference in an older Quebec home.

Finally, some work on exposed foundations is eligible, especially in older unfinished basements. For a broader overview of every renovation rebate available in Quebec, see our renovation financial aid guide.

Not covered: purely aesthetic window work, heating system replacement (that falls under LogisVert and Chauffez vert), and any work done without an EnerGuide pre-assessment.

Mistakes to avoid

Five traps account for the vast majority of rejected applications or smaller-than-expected payouts.

• Starting work before the EnerGuide pre-assessment. Without an initial report as the baseline, there is no way to measure gains, so no amount can be calculated. This is the most common and most expensive mistake.
• Choosing a non-certified energy advisor. Only advisors on the official list can produce a report recognized by Rénoclimat. An off-list advisor invalidates the whole process.
• Documenting installed materials poorly. For windows and doors, the exact ENERGY STAR rating must be proven with a detailed invoice. For insulation, the R-value added must be documented.
• Letting too much time pass between the pre- and post-assessments. The program enforces a maximum window between the two: confirm the current limit at the moment of the pre-assessment so you can plan.
• Not stacking with other eligible programs. The LogisVert program covers the mechanicals while Rénoclimat covers the envelope: the combination is designed by the program authors themselves. The grant programs page lists everything that can be combined.

Frequently Asked Questions

What is an EnerGuide assessment?

It is a technical inspection performed by a certified energy advisor. It combines an airtightness test (blower door), a visual check of existing insulation, and a standardized calculation of the home's theoretical energy consumption. The pre-assessment serves as the baseline and the post-assessment confirms the gains actually achieved by the work.

How much does the EnerGuide assessment cost?

The assessment is paid privately: the advisor invoices the homeowner directly. The cost varies with the size and complexity of the home and the region. A portion of the cost is reimbursed through Rénoclimat once the work is done and the post-assessment is complete. Get quotes from a few certified advisors before booking.

How long between the pre- and post-assessments?

You need enough time to do all the work between the two visits, but not so long that you exceed the maximum window the program enforces. In practice, several months are typical for a comprehensive envelope project (insulation, air sealing, windows). Check the current limit on the official site before planning the schedule.

Can you combine Rénoclimat with other rebates?

Yes, and it is in fact the winning strategy in Quebec. Rénoclimat stacks naturally with Hydro-Québec's LogisVert for mechanicals (heat pump), with the federal Canada Greener Homes loan for zero-interest financing, and sometimes with municipal rebates. None of these programs penalizes you for claiming another.
