Diagnostic
When several signs appear, OPTI-FENETRE is often more cost-effective.
The program is built for homes where several openings have issues at the same time, while the frames do not necessarily need replacement.
Permanent fog between panes
Windows that close poorly or let air through
Patio doors that are hard to slide
Crushed or missing weatherstripping
Cracked or loose caulking
Several repairs needed at the same time

Frequently asked questions about OPTI-FENETRE.
What is the OPTI-FENETRE program?
It is a complete restoration plan for your existing doors and windows. Instead of replacing everything, Vosthermos fixes the failing components: sealed glass, hardware, weatherstripping, caulking, screens and adjustments.
Is it cheaper than a full replacement?
In most cases, yes. The program keeps frames that are still in good condition and replaces only the components causing problems. Savings can reach 60 to 70% depending on the project.
Does it improve energy performance?
Yes when the losses come from failed sealed units, worn weatherstripping or deteriorated caulking. The diagnostic identifies the repairs with the highest impact.
Can you also replace screens and hardware?
Yes. The program can include screens, handles, rollers, locks, cranks, mechanisms and adjustments based on the condition of each opening.
Where is the program available?
The service is available in Montreal, Laval, Longueuil, Brossard, Saint-Hyacinthe, Granby and many South Shore cities.
