Travel Trailer Window Replacement

Travel trailer window replacement costs $200–$700 per window installed. Trailers have no windshield, so every opening is a framed tempered unit held in by an outer flange and an inner clamp ring — a 45–90 minute job once the correct size arrives. Sizing is by rough opening and wall thickness, not by model, so measuring correctly matters more than knowing your brand.

What drives travel trailer window pricing

Trailer windows are commodity parts from a handful of suppliers — Kinro, Philips, Lippert — so the cost is mostly size and pane count. The install itself is simple: back out the inner ring screws, push the unit out, clean the old butyl, re-tape, reset and re-clamp.

Small single-pane window: $200 – $350 installed
Standard living-area window: $300 – $500 installed
Large panoramic or dual-pane unit: $450 – $700 installed
Torklift or teardrop egress window: $350 – $600 installed
Butyl tape and clamp-ring hardware: $25 – $75

Measure the rough opening, not the glass

Order by three numbers: the rough opening width and height (measured inside the wall cutout, not the visible glass), and the wall thickness. Wall thickness sets the clamp-ring depth — a window built for a 2-inch wall will not clamp on a 2.5-inch wall.

Also note whether the unit is a slider, a vertical slider, or a torque/awning-style crank-out, and which side the screen sits on. A good supplier can match nearly any older unit from those five data points.

Fogged dual-pane windows

Condensation between the panes means the seal has failed. On a trailer, defogging services that drill, dry, and re-seal run $150–$300 per window, and full replacement runs $450–$700. Defogging restores clarity but not the original insulating value.

Travel Trailer glass FAQs

How much does a travel trailer window cost to replace?

$200–$700 installed per window depending on size and whether it's single or dual-pane.

Can I replace a travel trailer window myself?

Many owners do — it's a clamp-ring and butyl-tape job. The risk is a leak from imperfect sealing, which is far more expensive than the window itself.

How do I find the right size?

Measure the rough opening width, height, and wall thickness. Suppliers match on those numbers, not on trailer brand or model.
