RV Window and Glass Replacement Serving Long Beach
About 10 min left
OCRV Center replaces RV windshields, side windows and fixed glass, and repairs the frames and seals around them. Side window replacement and reseal runs $250 to $3,500, and Class A windshield replacement, which involves large one or two piece laminated glass, runs $2,500 to $7,500.
RV glass is a different animal from automotive glass. A Class A windshield is a one or two piece laminated panel that can measure over eight feet across, weighs enough to require multiple people to handle, and sits in a frame that has been flexing over road inputs for the life of the coach.
Side windows on coaches are usually Hehr, A and E or Kinro units, and the failure is almost never the glass. It is the seal, the frame corner welds, or the sealant where the frame meets a sidewall that has been quietly delaminating behind it.
Diagnosing a Window Leak Correctly
Water showing up on an interior wall below a window has three plausible sources, and only one of them is the window. It can be the window frame seal, the sealant at the frame to sidewall joint, or a roof leak that traveled down inside the wall cavity and emerged at the first horizontal surface it found.
Replacing a window to solve a roof leak is a common and expensive mistake. We water test with the interior panel off so the actual entry point is observed rather than inferred.
Class A Windshield Replacement
One and two piece Class A windshields are set into a frame with a rubber gasket or urethane, depending on the coach. Removal without cracking the replacement requires the frame to be clean, true and free of corrosion, and on older coaches it frequently is not.
Frame corrosion has to be addressed before the new glass goes in. Setting expensive laminated glass into a pitted frame guarantees a leak and risks stress cracking the panel as the frame continues to deteriorate underneath it.
Availability and Lead Time
Class A windshield glass for out of production coaches is often on extended backorder or discontinued outright. We check availability before the vehicle is scheduled rather than after it is disassembled.
Where the original is unavailable we source pattern glass, which fits correctly but may differ slightly in tint. We tell you that in advance.
Window Frame Repair and Reseal
Frames corrode at the corners where the weld or crimp sits, and once a corner opens the whole assembly loses its water seal regardless of how much sealant is applied from outside.
We remove the frame, repair or replace the corner, clean the sidewall opening back to sound material, and reset with fresh butyl and a proper exterior seal. Applying sealant over a failed frame from the outside is the single most common ineffective repair we see and it buys about one rainy season.
Sidewall Damage Behind the Window
A window that has leaked for more than a season has usually damaged what is behind it. We inspect the opening for wet substrate and rotted framing before setting new glass.
If we find it, the repair scope grows, and that is a conversation we have before proceeding rather than a surprise on the invoice. Setting a new window into a rotted opening means it has nothing sound to seal against.
What Is Included

- Glass availability and lead time verified before the vehicle is scheduled
- Frame corrosion repaired or the frame replaced before new glass is set

- Fresh butyl and correct exterior sealant rather than a surface bead over a failed seal
- Interior trim reinstalled and the assembly water tested before delivery
Our Process
- 1
Leak Diagnosis
Interior panel removed and the assembly water tested so the actual entry point is observed, not guessed.
- 2
Parts Verification
Glass and frame availability confirmed, lead time communicated before scheduling the vehicle in.
- 3
Removal
Glass and frame removed with the opening protected, existing sealant cleaned back to bare substrate.
- 4
Opening Inspection
Substrate and framing checked for moisture and rot, with any additional scope discussed before proceeding.
- 5
Frame Service
Corners repaired or the frame replaced, corrosion addressed and the sealing surface made true.
- 6
Installation
New glass set with fresh butyl or urethane as the design requires and exterior sealed correctly.
- 7
Water Test
Assembly tested under sustained water before interior trim is reinstalled and the vehicle released.
Frequently Asked Questions
How much does an RV windshield cost to replace?
A Class A one or two piece windshield replacement runs $2,500 to $7,500 installed, driven mostly by glass cost and whether the frame needs corrosion repair before new glass can be set. Side window replacement on a coach runs $250 to $3,500. The largest variable on older units is availability, since Class A glass for out of production coaches is frequently on extended backorder or discontinued.
Water is coming in below my RV window. Is the window the problem?
Possibly, but not necessarily. Water appearing on an interior wall below a window has three common sources: the window frame seal, the sealant where the frame meets the sidewall, or a roof leak that traveled down inside the wall cavity and emerged at the first horizontal surface. Replacing a window to fix a roof leak is a costly and frequent mistake, so we water test with the interior panel removed to observe the actual entry point.
Can you just reseal my window instead of replacing it?
If the frame is sound, yes, and a proper reseal means pulling the frame, cleaning the opening back to bare substrate and resetting with fresh butyl. What does not work is running a bead of sealant around the outside of a frame whose corners have already corroded open, which is the repair most owners have already tried. That buys roughly one rainy season before the leak returns.
What happens if there is rot behind my window?
We tell you before proceeding rather than after. A window that has leaked for more than a season has usually wet the substrate and sometimes rotted the framing behind it, and new glass set into a rotted opening has nothing sound to seal against. If we find it during removal, we stop, show you, and quote the additional substrate and framing repair so you can decide on the full scope with the actual condition in front of you.
