Frequently asked questions

Vosthermos offers a complete range of services for your doors and windows: sealed glass unit replacement, wooden door repair and restoration, custom screen door manufacturing, hardware replacement (handles, locks, rollers, etc.) and defogging. We serve the greater Montreal area within a 100km radius of Saint-Francois-Xavier. All our work is performed by experienced technicians with over 15 years of expertise.

Defogging involves removing moisture trapped between the two panes of a sealed unit without replacing the unit itself. It's a temporary and less expensive solution, but doesn't fully restore the glass's insulating properties. Sealed glass replacement involves installing a brand new sealed unit that provides optimal thermal insulation and is covered by our 10-year warranty. We generally recommend replacement for a lasting result and better energy efficiency.

Our 10-year sealed glass warranty specifically covers: condensation between panes (seal failure), glass manufacturing defects and breakage due to material defects. It does not cover accidental breakage, third-party damage, normal wear of mechanical components or damage from improper use. For hardware, the warranty covers manufacturing defects per the manufacturer's terms.

Our team will evaluate your claim quickly, usually within 48 business hours. If approved, we schedule the replacement at no additional cost. Always keep your original invoice as proof of purchase.
