RV Side Window Replacement

RV side window replacement typically costs $250–$900 installed per window, depending on size, whether the frame is reused, and whether the unit is single or dual-pane. Most RV side glass is tempered safety glass in an aluminum or vinyl frame, so a broken pane usually means replacing the full window assembly rather than just the glass — glass-only swaps are only possible when the frame is undamaged and the pane is field-serviceable.

What an RV side window replacement actually costs

Price is driven by three things: the size of the opening, whether the window is single or dual-pane, and whether your installer can reuse the existing frame. A small single-pane bunk-area window in a travel trailer may land at $250–$400 installed. A large dual-pane living-area window on a Class A diesel pusher runs $650–$900 and sometimes more if the unit is a discontinued size that has to be custom fabricated.

Labor is a small slice of that number on trailers and fifth wheels — most framed RV windows are held in by an inner clamp ring and a dozen screws, so the removal and reset is 45–90 minutes. On motorhomes with bonded or flush-mount glass, labor climbs because the old urethane bead has to be cut out and the opening prepped.

Small single-pane window: $250 – $400 installed
Standard living-area window: $400 – $650 installed
Large or dual-pane window: $650 – $900+ installed
Glass-only swap into a good frame: $150 – $350
Custom-fabricated pane for a discontinued size: add $200 – $500

Why RV side glass can't be chip-repaired

Windshields are laminated — two glass layers bonded around a plastic interlayer — which is why a chip can be filled with resin. RV side windows are almost always tempered, heat-treated so they break into small blunt pellets instead of shards. That safety property is also why there is nothing left to repair: a tempered pane either survives intact or turns into a pile of cubes.

If your side window is cracked rather than shattered, it is very likely laminated (some newer frameless coaches use laminated side glass for sound deadening). Laminated side panes can sometimes be crack-stabilized, but replacement is still the standard fix because the crack will migrate with road vibration and temperature cycling.

Getting the right window: measure before you order

RV window sizing is not standardized across brands, and manufacturers changed suppliers mid-model-year more often than owners expect. A shop needs the outside frame dimensions, the wall thickness the frame clamps onto, the radius of the corners, and whether the unit is a fixed, sliding, or awning-style window.

Photograph the window from inside and outside, and check for a supplier sticker or etched code in a corner of the glass — Hehr, Kinro, Lippert, Motion Windows, and Peninsula are the common OEM suppliers, and a code from any of them shortens sourcing dramatically.

RV Side Window FAQs

Can you replace just the glass in an RV window?

Sometimes. If the frame is straight and the window is a fixed or field-serviceable design, a shop can set a new pane into the existing frame for $150–$350. If the frame is bent, corroded, or the window is a sealed dual-pane unit, the whole assembly gets replaced.

How long does RV side window replacement take?

The install is typically 1–2 hours per window. The wait is in sourcing: 3–5 business days for a common size, up to 20 business days for a dual-pane or discontinued unit that has to be built to order.

Does insurance cover an RV side window?

Comprehensive coverage generally applies to side glass broken by road debris, hail, vandalism, or a break-in. Because side windows often cost less than a typical $500–$1,000 RV deductible, many owners pay out of pocket. Full glass coverage, where available, waives the deductible.
