Water Intrusion is One of the Most Common — and Costliest — RV Failures
Water intrusion is one of the most widespread and expensive issues RV owners experience. Over time, roof and body sealants naturally dry out, shrink, crack, or separate. When that happens, water follows the path of least resistance and can enter ceilings, walls, floors, slide-outs and compartments — often long before any visible symptoms appear.
Moisture can enter from:
- Rain and snow
- Washing your RV
- High humidity and condensation
- Improper sealing around roof penetrations, windows, or wall seams
Once inside, water intrusion can lead to:
- Structural damage / delamination
- Damaged wall and floor substrate
- Hidden mold and mildew growth
- Soft floors & wall failure
- Rot and long-term structural weakening
Unfortunately, by the time visible staining or damage shows — the dry rot may already be significant.
Free Exterior Sealant Evaluation
To help prevent severe water damage, we offer a free exterior inspection of your RV’s roof and body sealants. Small sealant failures caught early can save thousands in future structural repair costs.
Did You Know?
Most RV manufacturers recommend inspecting exterior sealants every 30 to 90 days. Many units leave the factory WITHOUT complete sealing in critical areas — making routine professional inspections even more important.
When sealants shrink, crack, or go missing — water gets in.
And when water gets in quietly — damage escalates quickly.

Straight Time Operation (Billing Notice)
Water damage repair is not billed flat-rate.
All water damage repairs are considered Straight Time Operations due to the unknowns involved behind walls, floors and structure until disassembly occurs.
Straight Time Operation:
Billing applies to diagnosis, repair time, material handling, and reconstruction based on actual technician time required. Rates vary depending on severity and complexity.
Labor charges are calculated according to the true time and effort required to safely and properly complete the job.
