RV DIY: Replacing a Frameless Dual Pane RV Window

By:  Kelly Barnett

4th May, 17


We've had two instances where we've had to replace windows in our 2011 Heartland Landmark Key Largo fifth wheel...both due to little bitty ROCKS. The first time it was one of the tall skinny windows that are on the either side of the couch. The most recent (just this past March) was the hallway window.

The first time our son, Zack, helped Michael replace the window while we were staying at the Ft. Sam Houston FamCamp in San Antonio, Texas. The second time, I was Michael's assistant...and again...we were at the Ft. Sam Houston FamCamp in San Antonio, Texas. If I can help...and found the process to be ridiculously easy...you can too!

Tools Needed: Screw driver, ladder, silicone caulk and caulk gun (optional)

Time Required: 1 hour (depending on size of window)

Removing the Window Treatments

Remove the valance by removing the screws holding it in place. Ours was held in place with two screws. Set the valance and the screws aside.

Remove the shade if you have one. Remove bottom screws first and then the top screws. Ours had two screws on the bottom and two screws in the top. Set the shade and the screws aside.

Removing the Old Window

Remove the screws that are holding window in place.  Ours was held in place with 26 screws.  Set the screws aside.

It helps to have someone on the outside of the window when the last few screws are removed, just in case.

Once the screws have all been removed you can remove the inside trim piece and set it aside.

Next, you'll need to free the window of its seal so that it can be removed.  Some pushing from the inside of the window should do it.

If the window is shattered like ours, be very careful not to cut yourself.  The glass should stay intact, for the most part, but the edges of the glass may crumble.  You might want to wear some gloves, which we did not, but should have.

Lift the old window out of the window opening and set aside.

Prep the Replacement Window

Apply a rubber seal, also called a gasket, to the inside lip of the replacement window.  We reused the gasket from the original window; however, it would probably be best to purchase a new gasket.

We applied a thin bead of silicone on the rubber gasket to ensure a good seal. This step is optional but doesn't hurt.

Installing the Replacement Window

When the gasket (and optional silicone) has been applied to the replacement window, the window is ready to install in the window opening.

Carefully lift the window into the opening. It should just slide right into the opening with no problems. Once in place, with a second person holding the window from outside, replace all of the screws.

Reinstalling the Window Treatments

Using the screws, you set aside, reinstall the window shade. Replace the top two screws first, followed by the bottom two screws.

?If you have the day and night shades, like ours, you may need to adjust the tension on the strings in order for them to move freely.

To adjust the tension, you have to loosen or tighten the strings. To do that you need to remove the screw and the cord tension eyelet at the bottom of the shade (attached to the wall) and adjust the length of the string…shorter to tighten or longer for to loosen. When the tension is to your liking you'll need to replace the cord tension eyelet and tighten it down.

When the shade is in place, reinstall the valance, using the screws you set aside. Place the valance on the two brackets and screw into them to hold in place.

With the window and window treatments in place you can now remove the plastic protective coating from the window.

RV There Yet Chronicles

My husband, Michael, and I have been living fulltime in our 2011 Landmark Key Largo since April of 2011 and LOVE every minute of it. 

When Michael retired from the US Army in October of 2012 (after 29 years of service) we hit the road and haven’t looked back. 

We usually work in the south Texas oilfields in the winter and spend time with our two sons and their families in the summer. We travel and sight-see as much and often as possible.
