Frequently asked questions

What exactly is the OPTI-FENETRE program?
It's a turnkey program that combines all our repair services into a single package: sealed unit replacement, hardware, weatherstripping, caulking, screens and door restoration. Instead of replacing your entire windows, we restore them for a fraction of the cost.
How much can I save?
On average, the OPTI-FENETRE program costs 60 to 70% less than a full replacement. For a typical home with 12 windows and 2 doors, that's savings of around $12,000.
Is the result as good as a replacement?
In most cases, yes. We replace the defective components (sealed units, gaskets, hardware) while keeping the frames that are still in good condition. The result: optimal thermal and acoustic insulation, mechanisms that work like new.
How long does the work take?
For a standard home, the work is generally completed in 1 to 2 days. That's much faster than a full replacement which can take 4 to 8 weeks.
Which cities do you serve?
We cover Montreal, Laval, Longueuil, Brossard, Saint-Hyacinthe, Granby and the entire area within a 100 km radius of our workshop.
Is there a warranty?
Yes, all work performed under the OPTI-FENETRE program is covered by our Vosthermos warranty. Sealed glass units are guaranteed for 10 years.
