2014 Thor A.C.E. Foggy Dual-Pane Window Replacement — Riverside, California
A 2014 Thor A.C.E. 30.1 had two fogged dual-pane side windows from failed perimeter seals. Rather than replacing the full frames, both glass inserts were reglazed into the original Kinro frames on site in Riverside in 2 hours 40 minutes, for $690 total — roughly half the cost of complete window assemblies.

Reglaze versus full window replacement
When a dual-pane RV window fogs, the glass is fine — the perimeter seal between the panes has failed and let moisture in. If the frame is straight and the slider hardware still runs, the insulated unit can be replaced inside the original frame at roughly half the cost of a complete assembly.
Full assembly replacement makes sense when the frame is corroded, bent, or when the original size is no longer manufactured. On this coach the Kinro frames were sound, so reglazing was the obvious call.
Why insurance did not apply
Comprehensive covers sudden accidental loss — a rock strike, hail, vandalism, a tree limb. A dual-pane seal that fails after ten years of thermal cycling is wear and tear, and every RV carrier excludes it.
That is worth knowing before you call: fogged windows are almost always an out-of-pocket repair, which is exactly why the reglaze route matters so much on multi-window jobs.
Frequently Asked Questions
Can a foggy RV window be fixed without replacing it?
The fog itself cannot be cleaned out — the moisture is sealed between the panes. But the insulated glass unit can usually be replaced inside the original frame, which on this job cost $690 versus $1,380 for complete assemblies.
How long does dual-pane window work take?
2 hours 40 minutes for two windows on this coach, with no cure time because the seal is mechanical rather than adhesive. The lead time is in building the glass — about six business days here.
