Floor & Interior repair costs
Inside the rig, the big-ticket repairs are structural: a soft subfloor, a cracked windshield, a failed window seal. These guides cover what floor and interior repairs cost and which ones you can put off without making things worse.

Floors: the finish layer or the subfloor?
Most RV floor repairs run $800 to $4,500, and one question decides where you land: did the water get through the vinyl and into the plywood underneath? Replacing surface flooring in a typical travel trailer costs $800 to $2,500 at a shop. Subfloor rot starts around $2,000 for a small area and passes $7,000 when it runs under cabinets, appliances, or a slide. A full structural rebuild can reach $10,000 to $12,000. The floor repair guide covers each tier.
For subfloor work, the square footage of rot matters less than what's bolted on top of it. A DIY patch costs $100 to $900 in materials, a shop charges $800 to $6,000 for a localized soft section, and a full-rig replacement that means pulling cabinets and fixtures runs $6,000 to $20,000. Don't sit on a soft spot. The sealed underbelly gives trapped water nowhere to evaporate, so the rot keeps working.
Windshields: what you drive sets the price
Try a chip repair first. Glass shops charge $55 to $65 for the first chip and $25 to $35 for each one after, and if you carry comprehensive coverage, most carriers waive the deductible for repairs, so the fix often costs nothing out of pocket. A quarter-size chip outside the driver's direct line of sight is almost always repairable.
Full replacement depends on the rig. A Class B uses the windshield of the van it's built on, so it's priced like any van at an auto glass shop. A Class A windshield is specialty glass made to order and runs $1,200 to $5,000 or more installed; owners of older coaches with discontinued glass have been quoted over $8,000 for both panes. If the coach is your home or a trip is booked, ask about the parts lead time before you ask about price. The RV windshield guide covers every class.
Side windows and the rest of the cabin
Side windows cost $80 to $350 in parts if you swap them yourself, or $350 to $900 installed. A basic slider or jalousie assembly from a parts site such as RecPro runs $115 to $190, frameless and dual-pane units run $250 to $600 in parts, and egress windows land at $600 to $1,500 installed.
An interior remodel is the widest range on the site: $300 to $1,500 for paint and hardware, $2,000 to $10,000 for a full DIY overhaul, and $15,000 to $28,000 or more when a shop does it all. The biggest driver isn't the RV's age or size. It's how much of the work you do yourself.

Will insurance or a warranty cover it?
- RV insurance may cover this when the cause is a covered peril (storm, collision, fallen tree), not gradual wear or neglect.
- An extended warranty or service contract may cover this if the failure is mechanical and the component is listed in your plan.
Coverage depends on your policy and the cause of damage. Confirm specifics with your provider.
