Last I heard the seals were $2000 plus, and labor ranged somewhere between 4 and 8 man hours depending on who does the replacement.

I have had the misfortune of having to replace both seals over a period of 24 months. As Jon indicated, it is an expensive experience. You could save yourself a little bit of money by ordering the seal direct from Prevost.

Key to a lasting installation of the replacement is the removal of the old glue/adhesive. That means a lot of scraping and it will account for some of the hours you will be charged for this job.

The installation of the new seal goes relatively fast. So I would say, you pay 2/3 for the labor of removing the old seal and cleaning-up and 1/3 for installing the new seal.

I have spoken to a couple of people who say that a leaking seal can be repaired. Like a bicycle inner tube. If you are handy and would like to give it a try, it would not be that difficult.

The hardest part will be the removal of the rail on top of the slide. This must be done so that the slide can be moved inside past the exterior wall. Only then can you remove or repair the leaking seal.

If you should attempt to do this, make sure that you know how to disable the slide pins. Otherwise … $$$$

In any event, the slide seals are something that can cause a big headache and a large bill. Been there, paid for that.

Slide seals are a replacement item and at some point are going to age and fail. When they do develop a leak such that they cannot hold pressure for any length of time it is unlikely they can be repaired for a number of reasons.

Ron is accurate in his assessment of where the labor is involved and because of it, even if leaks could be repaired, it is at best a 50/50 chance the leak is accessible from the front side without removal, and then it is highly likely because of its shape the leak will be on the portion of the seal that flexes and makes a sharp bend as it collapses when the slide room is moving.

Once age starts to cause leaks, whether due to cracking at the flex joint, or leakage due to abrasion the life of the seal is over.

A single person can change a slide seal. It works better with two because handling something like a seal isn’t easy because of the risk of getting it dirty or located incorrectly. Not many tools are required, but the removal and scraping process requires a good technique or just a whole lot of time to insure the mounting surface is free of all the old adhesive.

A scaffold is almost a requirement so those working on the replacement can move freely across the entire width of the slide.

And as Ron points out whoever replaces the slide had better know and understand how to retract and disable the slide pins, know how far and the process to bring the slide room in past the seal, and know and understaand how to remove the slide room top angle and reseal it correctly when it is reinstalled. An owner willing to take the time, who has friends to help and who will do the replacement carefully can save the cost of labor, but is a criticaal step positioning the seal correctly because there is no second chance. The adhesive is there to stay.
