Tools and Materials Needed

Before starting the replacement, gather these tools and materials:

  • New RV window (matched to your RV’s size and style)
  • Screwdrivers (Phillips and flathead)
  • Putty knife or plastic trim removal tool
  • Butyl tape or RV window sealant
  • Caulk gun
  • Painter’s tape
  • Rubber mallet (optional)
  • Drill (if necessary for mounting screws)
  • Rags and isopropyl alcohol for cleaning

Step 1: Remove the Old Window

1. Remove the Interior Window Frame

Most RV windows are secured by an interior trim ring, which needs to be removed first.

  • Use a screwdriver to remove all screws around the window frame inside your RV.
  • Carefully pull the interior trim ring away from the wall.

2. Cut Through the Old Sealant

The window is typically sealed to the RV’s exterior with butyl tape or caulk.

  • Use a putty knife or plastic trim removal tool to gently separate the window from the RV’s exterior wall.
  • Avoid using excessive force to prevent damaging the RV siding.

3. Carefully Remove the Window

Once the seal is broken:

  • Push the window outward from the inside.
  • Have someone outside hold the window to prevent it from falling.
  • Set the old window aside and inspect the opening for any damage.

If your RV window frame or structure is compromised, consult Daisy RV for professional repair services before installing the new window.

Step 2: Prepare the Window Opening

4. Clean the Window Frame Area

  • Remove all old butyl tape, caulk, or adhesive residue from the window opening.
  • Wipe the surface clean with isopropyl alcohol to ensure a strong seal.

5. Apply Fresh Butyl Tape or Sealant

  • Place a strip of butyl tape around the edge of the window opening.
  • Ensure an even application to prevent gaps or leaks.

Step 3: Install the New Window

6. Position the New Window

  • Have a helper hold the new window in place from the outside.
  • Align it properly with the opening before pressing it against the sealant.

7. Secure the Window in Place

  • Inside the RV, reattach the interior trim ring with screws.
  • Tighten the screws evenly in a crisscross pattern to apply equal pressure around the frame.
  • Do not overtighten, as this could warp the frame or break the glass.

Step 4: Seal and Finish the Installation

8. Apply Exterior Sealant

  • Use an RV-safe sealant (such as self-leveling caulk) around the outer edge of the window.
  • Smooth the sealant with a finger or tool to ensure full coverage.

9. Check for Gaps and Air Leaks

  • Inspect the window from both inside and outside to ensure a snug fit.
  • If needed, add extra sealant to any small gaps.

10. Allow the Sealant to Cure

  • Let the window sit undisturbed for 24 hours to allow the sealant to fully cure.
  • Avoid driving in wet conditions until the sealant is set.

Step 5: Test the New Window

11. Open and Close the Window

  • Ensure smooth operation of the window latch and screen.

12. Perform a Leak Test

  • Spray water around the window and check for any leaks inside.
  • If you notice any leaks, apply additional sealant as needed.
