The short answer
Window service covers resealing leaking frames, replacing failed butyl, reglazing fogged dual pane units, and full window replacement. Work runs $250 to $3,500, or 1 to 14 hours at $210 per hour plus parts, with a water test on every completed opening.
01
What this work actually involves
Window seal failure is the single most common water entry point we find on Southern California RVs, and the mechanism is straightforward. RV windows are bedded to the sidewall in butyl tape, not caulk, and butyl has a service life. Ultraviolet exposure and thermal cycling harden it until it no longer flows to fill the gap, and then the first driving rain off the Pacific pushes water past the top flange and into the wall cavity. The damage that follows shows up months later as a stained wall panel or a delaminated exterior skin, several feet below the window.
The mistake we correct most often is a bead of silicone run around the outside of a leaking window. That traps water behind the frame instead of keeping it out, and it turns a resealable window into one that has to come out and be cleaned to bare. A correct reseal means removing the window entirely, scraping the old butyl off both the frame and the wall, inspecting the substrate behind it, and rebedding on fresh butyl with the screws torqued in sequence so the tape compresses evenly.
Dual pane windows fail differently. When the perimeter seal on an insulated unit lets go, moisture enters between the panes and you get permanent fogging and mineral staining. That cannot be cleaned and it is not a reseal. The glass unit itself is replaced or reglazed. This failure accelerates in the low desert, where a window can go from a 45F night to a 130F surface temperature by mid afternoon, cycling the seal every single day of the summer.
Systems and brands we work on: Hehr, Kinro, A&E.
Location: All work is performed at our Yorba Linda facility. We do not offer mobile, roadside, or fleet route service.

03
When you need this service
- Staining on the interior wall directly below a window
- A dark or soft area on the exterior wall beneath a window frame
- Fogging, condensation, or mineral haze between the panes of a dual pane window
- Hardened, cracked, or shrunken sealant visible at the frame edge
- A window that has been previously sealed with silicone from the outside
- A slider that binds, will not latch, or has a torn screen
- Water appearing on the interior sill after a driving rain

How we do it, step by step
- 01
Leak confirmation and metering
The suspect opening is water tested and the wall metered around it, so we know whether the window is the actual source before anything comes out.
- 02
Window removal
Interior trim ring off and the window removed as a unit. A leaking window is not diagnosable from outside, because the damage lives on the hidden face of the flange.
- 03
Substrate inspection
Wall opening inspected and metered with the window out. Soft substrate or a delaminated skin edge found here changes the scope and gets documented before we continue.
- 04
Surface preparation
Old butyl scraped completely off both the frame and the wall to bare surface. New tape over old residue will not bond, which is why a partial reseal fails.
- 05
Rebed and torque sequence
Window bedded on fresh butyl and screws drawn down in sequence so the tape compresses evenly instead of squeezing out at one corner and staying loose at another.
- 06
Glass or hardware service
Fogged dual pane units replaced, tracks and latches serviced, and screens replaced while the window is out and accessible.
- 07
Water test and trim
Opening water tested at pressure from multiple angles, then the interior trim ring reset and the sill checked dry before delivery.

Questions about window reseal and replacement
Frequently asked questions
How much does an RV window reseal cost?
Window work runs $250 to $3,500, or 1 to 14 hours at $210 per hour plus materials. Resealing a single small window sits near the low end. Removing and rebedding every window on a coach, replacing two fogged dual pane units, and repairing substrate found behind a frame sits at the high end. Glass and windows are billed at parts markup.
Can you just caulk around the outside of a leaking window?
No, and we will not do it. Running silicone around a window frame traps water behind the frame instead of excluding it, and it turns a straightforward reseal into a job where the frame has to be cleaned to bare. A correct reseal removes the window, strips the old butyl from both surfaces, and rebeds on fresh tape.
Why are my dual pane windows fogged, and can they be cleaned?
The perimeter seal on the insulated glass unit has failed and moisture is now between the panes. It cannot be cleaned, because the surfaces are inside a sealed assembly and the mineral staining is etched. The glass unit is replaced or reglazed. Low desert heat cycling accelerates this failure considerably compared to coastal storage.
How often should RV windows be resealed?
Inspect the butyl annually and expect to reseal on a five to ten year horizon in this climate, sooner for a coach stored uncovered in the desert. Butyl hardens from ultraviolet exposure and thermal cycling rather than from mileage, so a low-mileage coach that sits in the sun is at higher risk than a high-mileage one that lives covered.
What if you find damage behind the window?
We stop, photograph the substrate, take moisture readings, and price the additional repair before going any further. Soft wall substrate or a delaminated skin edge behind a window is a common finding on a leak that has been running for a season or two, and putting the window back over it simply hides the problem for another year. On an insurance claim, that photographed finding is what supports the supplement.
