Anything can happen to a window, even in an RV. Replacing a regular house window can be a pain in the neck. It depends on the type of window, what the house is built with, and much more. Time consuming and exacting. Unless it’s done perfectly, the window won’t open.
An RV window isn’t as fussy- in fact you can do the job yourself, and its easier if you have a partner.
For the purposes of this article, RV will refer to all RV vehicles- travel trailers, Class A, B and C RV’s, Van conversions, etc.
Why would you replace an RV window? Road debris can break or shatter a window, stray toys (such as baseballs), debris thrown by storms, etc., can all break a window. Age works it’s unrelenting magic on the seal, and single-paned windows need to be replaced with double-paned insulated windows for energy efficiency.
RV supply stores carry replacement windows, and several online companies carry them as well. Contact your RV’s manufacturer to see if they carry windows for your specific RV.
If you have a vintage RV, your manufacturer may no longer exist. Don’t despair- several companies are happy to help you find the closest replacement size or build a custom window for your RV. It may cost a little more, but it will fit and work beautifully. Be prepared to give specific measurements for the window, and for the thickness of your RV wall. That makes a huge difference- if the wall is too thin, the window will fall out, if it’s too thick, the screws won’t attach the clamp to the window, and you’ll lose it.
This article is geared toward the clamp-style window. These are the most common, and the easiest to deal with.For motor home windshields, go to an authorized and licensed dealer or auto shop. That’s not a DIY job.
You will need:
· A drill or screwdriver
·.
Note:
· There should be 1/8″ clearance around the window in the opening. This allows for expansion and contraction of the materials and wall frame.
·.
· Only use the fasteners that come with the window- shorter screws won’t hold, and longer ones could puncture the outside window flange, creating leaks or worse damage.
· If your window is in good shape but you suspect a leak, you can use this article to replace the sealer by following the same steps. Use butyl tape instead of the clay tape for a near “forever” seal.
Step One:
Take down the curtains and curtain rods inside the trailer. Set these aside. Remove the new window from the package and remove the screen. Open the window- this will make it easier to handle.
Step Two:
Using the screwdriver or drill, remove the clamp ring from inside the RV. This is the window frame inside. Your helper should be holding the window from the outside so it doesn’t crash to the ground.
If you don’t have a helper, use outdoor duct tape to hold the window in place. Use glue remover later to clean up.
Step Three:
While your helper holds the window, release the old seal tape by gently working the paint remover tool around the perimeter next to the trailer.
Lift the old window out of the opening and set aside.
Step Four:
Completely clean the old tape and any residue off the window opening. Note any damage to the RV. Inspect the inside of the walls for any water damage. This can’t be ignored.
Place the window face down and apply the seal tape to the inside of the flange. Overlap the ends by at least a half inch. Some installers apply the seal tape to the RV window opening- either way is fine. Remove the paper on the seal tape.
Step Five:
Have your helper lift the new window into place. Go inside the trailer and make sure the window is centered in the opening. Use the shims and tape measure if necessary.
Once centered, place the clamp ring over the window opening and secure with the fasteners that came with the window.
Step Six:
Replace the window hardware.
Step Seven:
Outside, clean up any squeezed out sealant, and apply a bead of outdoor silicone around the window flange.
Dispose of the old window properly.
You’re done. Buy your assistant dinner, a soda or a movie. Help him or her with their windows.
