Start by getting accurate measurements, since most trailer home window sizes differ from standard house windows.

  • Measure the width and height of the window opening from inside edge to inside edge.

  • Easy-to-clean surfaces and sturdy locking mechanisms.

Specialized retailers often provide windows tailored to mobile homes to help you find the perfect match.

3. Remove the Old Window

Carefully remove the existing window to avoid damaging the surrounding wall.

  1. Unscrew the old window frame from the inside and outside.
  2. Use a utility knife to cut any caulk or sealant around the frame.
  3. Gently pry out the frame and sash, removing any debris left behind.

4. Prepare the Opening

Before installing your new window:

  • Clear away old caulk, nails, and screws.
  • Inspect the framing for rot or water damage and complete any needed repairs.
