Are you aware that mobile home windows do not only serve to let in light? In addition to protecting you from outside forces, they also add beauty to your home and may affect the energy efficiency of your home’s heating and cooling.
If you feel a draft by your mobile home windows, even if the windows are shut, it is a clear indicator that they do not seal properly. If air is getting in, and you’re feeling a draft, the cost to heat and cool the space will be higher! Luckily, replacing mobile home windows with vinyl siding is a great way to update the aesthetic of your mobile home as well as create a more efficient and durable home. Vinyl siding made its way to the market in the late 1950’s and has become a common choice in mobile homes because it is economical, and requires very little maintenance.
In this complete guide, we will go step-by-step through the mobile home replacement windows process. If you have to replace your mobile home windows because of damaged frames that require a full frame replacement, or if you just want to upgrade the materials in the existing windows, we will provide you with everything you need to know about replacing mobile home windows using vinyl siding. Let’s get started on transforming your living space!
Understanding Mobile Home Replacement Windows
Mobile home windows differ significantly from those found in traditional houses, requiring specialized knowledge for successful replacement. Understanding these differences helps ensure you select the right windows for your home’s specific needs.
What makes mobile home windows different
Unlike normal house windows that can be purchased in hundreds of different size configurations, mobile home windows typically come in three standard sizes–30″ x 60, 36″ x 54″ and 36″ x 60″. In addition to the sizes, there are more limited options for materials of the window frames. Common window frame material options for traditional homes might include wood, wood clad, aluminum, vinyl, fiberglass and composite, but the options for mobile homes are largely limited to aluminum and vinyl frames.
The criteria for installation of the windows can vary as well. When installing mobile home windows, the windows often do need a special mounting flange to mount to the narrower wall cavities in manufactured homes. This design consideration is largely due to the basic construction differences between mobile homes and traditional homes; mobile homes are built smaller, lighter and with lower density materials than traditional homes.
Types of replacement mobile home windows
Mobile home replacement windows come in several varieties to suit different needs:
Frame Materials:
- Vinyl frames provide excellent energy efficiency and require minimal upkeep. Made from polyvinyl chloride (PVC) with UV stabilizers, they’re affordable yet durable.
- Aluminum frames offer strength, lightness, and nearly maintenance-free performance. They resist corrosion, making them ideal for humid or coastal locations.
Glass Options:
- Single-pane windows are the most basic option but offer poor insulation.
- Double-pane windows feature two glass panes with an air gap between them, providing much better insulation.
- Thermal pane (triple-pane) windows contain three panes of glass separated by two air gaps, offering superior energy efficiency.
Window Styles: Various styles work well in mobile homes, including double-hung, sliding, casement, awning, and fixed picture windows, each providing different benefits for ventilation and esthetics.
Why vinyl siding matters in window replacement
Vinyl siding is a key component of the window replacement process. First off, it operates differently than building materials such as wood or brick—it is a more flexible material that will shift throughout the installation process. Additionally, vinyl siding is temperature sensitive—it will expand and contract with changes in weather or temperature, particularly one lives in a climate with freeze-thaw cycles.
While replacing windows, the installer will need to pay particular attention to potentially damage the siding. Potential problems include cracking brittle vinyl siding, damaging the J-channel which holds the window in place, and using improper cutting utensils. However, the advantages of vinyl siding outweigh its flaws; it has improved insulation, which increases energy efficiency and may lower heating and cooling costs for the homeowner.
Planning and Measuring for a Perfect Fit

Accurate measurements make all the difference when replacing mobile home windows. A seemingly minor error of even 1/4 inch can lead to significant problems during installation, causing gaps, drafts, and energy inefficiency.
How to measure for mobile home replacement windows
The measurement process for mobile home windows requires precision and attention to detail:
- Width measurement: Take three horizontal measurements—across the top, middle, and bottom of the window frame. Always use the smallest measurement as your final width.
- Height measurement: Similarly, measure vertically on the left side, center, and right side of the frame. Record the smallest measurement as your final height.
- Check for square: Measure diagonally from corner to corner in both directions. If these measurements differ by more than 1/4 inch, your opening is out of square and may require adjustments during installation.
- Depth consideration: For insert-style windows, measure the depth from inside stop to outside stop. Most replacement mobile home windows need about 3-1/4 inches of depth[9].
Remember to measure each window individually, as settling and frame shifts can cause size variations throughout your mobile home.
Choosing the right size and style
Windows for mobile homes are available in three standardized sizes: 30″ × 60″, 36″ × 60″, and 36″ × 54″, with actual dimensions likely to vary slightly.
In addition to size, please factor in:
How frequently you move your mobile home
The ease of removing windows to move the mobile home
A comfortable amount of glass
The amount you are willing to invest in windows with long-lasting frames or secure windows that have features similar to your home.
You can choose frame materials (vinyl or aluminum) or the style of either a single-hung, horizontal sliding, or casement window that suits your ventilation preferences and appeal.
Ordering custom vs standard windows
While standard sized windows may seem to be the most economical choice they are not necessarily the best option. Many manufactured homes have shifted over time, which has created non-standard openings.
To ensure the best fit, buy windows from a supplier or manufacturer that specializes in mobile homes. These manufacturers have experience with manufactured housing and understand the nuances involved in manufactured housing.
If you are going to choose custom windows then it’s typically worth it even if they cost more, even a little costly in the upfront process. Often DIYers make mistakes when replacing mobile home windows such as not ordering the right windows, taking incorrect measurements, and in installation skills in the process can lead to costing more than hired professionals does in the installation process.
Regardless of choosing the right to windows, standard and custom, taking critical measurements will always be the critical first steps towards replacing a window in a mobile home.
How to Install Replacement Vinyl Windows

Now that you’ve prepared properly, the actual replacement process for mobile home windows can begin. With the right approach, even a DIY enthusiast can achieve professional results.
Remove old windows and prep the opening
First, remove window coverings and carefully take out the trim using a pry bar or putty knife. Cut through existing caulking with a utility knife, then gently pry out the old window. Afterward, thoroughly clean the opening, removing all debris and old sealant with a steel brush. Inspect for rot or damage, especially in corners, and make necessary repairs before proceeding.
Install flashing and weatherproofing layers
Proper flashing is crucial for preventing water infiltration. Apply a waterproof membrane around the opening, starting at the bottom. Make sure the flashing’s flange tucks behind the siding against the sheathing. For the header, ensure the rain-shield laps over the flange, whereas at the sill, tuck the rain-shield behind the flashing. This “shingle-style” installation creates an effective moisture barrier.
Fit and secure the new window
Before permanent installation, dry-fit your replacement window to verify proper sizing. Next, apply putty tape or caulk to the back of the mounting flange—consider double thickness at the top for extra protection. Position the window with assistance, ensuring it’s level and centered. Initially, insert screws in the middle of each side without fully tightening. Check window operation, subsequently secure remaining screws working outward toward corners.
Seal and insulate for energy efficiency
Finally, apply quality silicone sealant around the exterior perimeter to create a watertight seal. Fill gaps between the frame and wall with expanding foam insulation. This attention to detail prevents drafts and substantially improves energy efficiency.
Finishing Touches and Maintenance Tips
The perfect finish after mobile home window installation ensures both esthetic appeal and lasting performance. Let’s complete our replacement project with these essential final steps.
Reinstall vinyl siding and J-channel
To reinstall vinyl siding, cut panels to the appropriate length with slight overlap at each end. Starting from the bottom, work upward, securing panels with siding nails. For a professional finish, install J-channel around windows for a clean transition between siding and window frames. Create proper drainage by mitering corners and including drainage tabs that direct water away from the window.
Add interior trim and caulking
For interior finishing, install jamb extensions to bridge the gap between the window and wall surface. Set the casing with a 3/16″ reveal from the edge for a professional shadow line. Secure with nails, then fill holes with putty. Apply paintable caulk along all seams to hide any gaps and create a smooth, finished look.
Inspect and test the new window
Examine the installation thoroughly. Check that the window opens, closes, and locks smoothly. Ensure all caulking is even without gaps that might cause drafts or leaks. Look for proper drainage and verify the siding installation directs water away from the window.
Tips to maintain mobile home windows
Regular cleaning with mild detergent extends window life. Inspect caulking annually for cracks or peeling, re-caulking as necessary to prevent leaks. For vinyl windows, avoid harsh abrasives—simply clean with a damp sponge and mild soap.
