How to Replace Your Windows in a Mobile Home

Posted on: 24 February 2015


No matter how well you take care of the windows on a single-wide or double-wide mobile home, weather and time will wear them down. The good news is that you can usually replace all of them within a three- to four-hour span. Want to know how? Keep reading.


Before you start taking the windows out, you'll naturally need a few supplies before beginning. Here they are.

  • A regular screw driver or power screw gun
  • Exterior putty tape
  • Silicone
  • A chisel or a tool for scraping
  • A 5/16-inch hex screwdriver
  • Crowbar (optional)
  • Hammer, mallet, or other pounding tool
  • Replacement window(s)

The Process

1. Use the screwdriver to pry the siding away from the window. You should see hex screws that secure the window. Don't use too much force, though. The siding should move easily. If they're not, inspect the area for additional screws holding the siding in place. Typically, you don't need to remove the siding to replace the windows, but some homes do have them. If this is the case, simply remove them first.

2. Use the 5/16-inch hex screwdriver to remove the hex screws from the window.

3. Pry the window away from the home using the screwdriver or a crowbar. There should be a flange that holds the hex screws in place. Because houses shift and window frames expand over time, it might take a little wiggling to get it loose.

4. Once the window is removed, make a mental note of where the old putty is on the frame. Use the chisel or some other tool to scrape it away. Take caution not to remove any wood or part of the house's frame.

5. Once finished, apply new putty complete around the frame. Do a good job. The putty does double-duty as a layer of insulation and adhesive. If you do a poor job here, you'll have drafty windows that might rattle when the wind blows.

6. Install the window by tilting it up and pressing the top part into the frame. Check to make sure it's aligned. Then, work your way down, pressing on the sides and the bottom of the frame. Use a hammer or mallet to secure it in place.

7. Reinsert the hex screws. The key here is to make sure they're snug, but not tight. If they're too tight, the window might not open. Test the window to make sure it opens and closes smoothly. If it doesn't, you may need to loosen or tighten the hex screws. Alternatively, you might need to use the hammer or mallet to pound on the window a little more.

8. Once you're certain that the window is secured and functions properly, apply sealant. Use it along the frame of the window to prevent drafts. Replace any siding if you removed it. Otherwise, simply take the old siding and pop it back into position.
