# Seal and Gasket Replacement

Seal replacement renews the weather seals around doors, windows, hatches, and body joints. Correct function depends on the opening being aligned first, since a seal can only work under even compression.

Range: $400 to $3,000

Collision estimates for insurance claim walk-ins carry no charge. Systems estimates are $150 and diagnostics are $285 per hour, both credited against an authorized repair.


## Alignment then seal

Fitting a new seal to a door that does not sit square is the most common wasted repair in this category. The gap the seal has to close is uneven, the seal compresses on one side and not the other, and it leaks in exactly the same place it did before.

We check and correct alignment first. Then the new seal has a chance of doing its job.

## Questions

**Why does my new seal still leak?**

Because the opening is not square. A seal closes an even gap. It cannot close an uneven one regardless of how new it is.

**How often should seals be replaced?**

When they harden, crack, or take a permanent set. In California sun that is typically several years, sooner on a vehicle that lives outdoors.

**Do reefer door seals matter more?**

Considerably. On a refrigerated body the seal is a thermal boundary as well as a weather one, and a poor seal shows up as a unit running continuously.
