Thermos replacement

What is thermos replacement?

The thermos is the sealed glass unit inside your window frame. When you notice fog or condensation between the panes, it usually means the seal has failed, not the entire window. Replacing just the thermos is a faster, cleaner and much more affordable solution than a full window replacement.

When should I consider replacing my window thermos?

Watch for these signs:

  • Persistent fog or moisture between the panes
  • Frost inside the windows in winter
  • Cold drafts with the window closed
If your frame is still in good condition, thermos replacement is often all you need.

Do you offer thermos replacement in Valleyfield and the surrounding area?

Yes, we offer this service in Salaberry-de-Valleyfield, Vaudreuil-Dorion, Beauharnois and nearby areas. It’s one of our most popular services, and we’ll always give you an honest recommendation based on the actual condition of your windows.

Energy efficiency & government programs

Is there a subsidy available for window replacement?

Yes. The Rénoclimat program offers financial assistance for replacing doors and windows with ENERGY STAR-certified products. Conditions and amounts are subject to change without notice. We recommend visiting the Transition Énergétique Québec website directly to confirm your eligibility before starting any work.

Are Fene-Tech windows ENERGY STAR certified?

Yes. Fene-Tech windows are ENERGY STAR certified and designed to meet the demands of the Quebec climate, making them eligible for Rénoclimat financial assistance.

Will replacing my windows actually lower my energy bill?

Well-insulated, properly installed windows reduce heat loss in winter and keep your home cooler in summer. The actual impact depends on the current condition of your windows and how many openings are replaced. It’s also a solid investment in your property value.
