LogisVert rebate
The LogisVert rebate for your attic insulation, made simple
R-50 roof insulation plus caulking: Hydro-Québec’s conditions explained plainly, who qualifies, and the documents the programme asks for.
What the programme pays
LogisVert is a Hydro-Québec programme. Its measure for roof insulation and caulking work pays a $1,500 rebate when all of the requirements are met. Both jobs have to be done: insulating the roof and caulking.
What follows is taken from Hydro-Québec’s LogisVert participation guide for the residential sector, under the rules in force on September 15, 2026 (version 1.10). Hydro-Québec can change the amounts and the conditions. Check your eligibility on the official site before you count on the rebate.
The house
The guide covers houses: single-family, semi-detached, row house, mobile home or cottage. Condos, multiplexes and apartment buildings don’t qualify.
The house also has to be heated mainly by electricity. Construction has to be finished, it has to be livable year-round, and it has to be in Quebec. And the measure is granted only once per dwelling.
Heated with natural gas or oil? Under these rules, the measure doesn’t apply.
The roof
The roof has to reach a thermal resistance of at least RSI 8.8, or R‑50, over its entire surface. At Isolation Cornerstone, we aim for R‑51 minimum.
The insulation is fiberglass or an equivalent material, with no health risk. And the guide requires the work to be done by a business registered with the Registraire des entreprises du Québec that holds the appropriate licences from the Régie du bâtiment du Québec.
The caulking
The guide asks for more than doors and windows. Every spot that leaks air has to be caulked, and in particular:
- windows, exterior doors and patio doors;
- attic access hatches;
- the kitchen range hood and bathroom fans;
- electrical outlets;
- fireplaces.
Installing or replacing doors or windows doesn’t count.
The invoices and the application
The application is made online only, from your profile on logisvert.ca. Email and mail are not processed. It has to be sent no later than 9 months after the work; if you group several measures, the clock starts with the first one.
The invoices have to be paid and show:
- their number, their date and the installation date;
- your name, your address and the address of the work;
- the company’s name, its Régie du bâtiment du Québec licence number and its GST and QST numbers;
- a description of the work, the material and the new thermal resistance, in RSI or R;
- the cost.
You attach proof of ownership, such as your tax bill or deed of sale. The first and last name on the invoices have to match that proof.
Two more details. The rebate can’t exceed the cost of the work before taxes. And when one application groups at least two different measures, for example a heat pump along with insulation and caulking, a bonus is added; the guide explains how it’s calculated.
What we do on our side
Isolation Cornerstone does the roof insulation and the caulking in the same project, with the same crew. You don’t have to find a second contractor.
At the visit, before any work, we go over the basic conditions with you. At the end, you get the invoices: before you send your application, check them against the list above. You file the online application yourself, and if a question stops you while you fill it in, give us a call.
The decision belongs to Hydro-Québec. Nobody can promise you the amount on its behalf.
What about Rénoclimat?
That’s a different programme, run by the Government of Quebec. Its new rules have been in force since October 1, 2026, and it requires an energy evaluation before and after the work. It can complement LogisVert when the work is separate. Its conditions are published on Québec.ca.

Hi! Pick a question and we’ll answer right here.
Choose a question
- Do I really have to do the caulking to get the rebate?
- Yes. The measure covers roof insulation and caulking together, and insulation on its own doesn’t qualify for the amount. Isolation Cornerstone does both in the same project.
- How long do I have to apply?
- Nine months after the work, at the latest.
- Am I sure to qualify?
- Only Hydro-Québec can tell you, based on its programme’s conditions. What we do on our end: we go over the basic conditions with you at the visit, before the work, so you don’t sign anything blind.
- My house is heated with natural gas. What does that change?
- Under the guide in force, the measure covers houses heated mainly by electricity, so it wouldn’t apply to yours. If your attic needs insulation, the visit is still free and we’ll quote it without the rebate.
