What we look for on your rig

During window leak repair, we start with how water enters: failed sealant, cracked gaskets, loose fittings, or condensation trapped after lay-up. We follow staining, soft spots, and musty areas until the path makes sense — not just the visible damage.

Lightweight plywood, luan, and foam insulation dry differently than residential walls. We keep structure open until readings are safe, document what must be removed, and explain what can stay.

What to expect when you call

You will speak with a coordinator, not an automated queue. Share your city, RV year/make/model, and symptoms — drip, bubble, spongy floor, or odour after storage.

We quote leak tracing, drying, or rebuild scope before major demolition. If insurance needs photos or moisture logs, we can provide them when useful.

Why act before the next trip

Water that sits continues along screw lines and edge grain. Mould follows moisture that never fully dried. A smaller repair today often prevents a full floor or wall replacement later.

After work completes, we note what was fixed, what to monitor, and when to re-check seals — especially before long hauls or winter storage.
