Window Replacement
Window Replacement Sized for Mobile Homes
Manufactured home windows are not the same size or construction as standard residential windows. Cal Star replaces them with units that fit the opening, seal properly, and improve comfort.

Warning Signs
Signs It Is Time to Replace Your Windows
Windows in older mobile homes were often single-pane and have decades of sun and frame wear behind them.
- Condensation or fogging between panes
- Frames that are cracked, warped, or difficult to open
- Noticeable drafts or hot spots near windows
- Rising energy bills with no other explanation
- Windows that will not stay open or will not latch
- Single-pane glass that lets heat and noise through
The Fix
What Cal Star Provides
Proper measurement, the right unit for a manufactured home opening, and installation that seals against Southern California weather.
Window Replacement
New windows sized to your home's existing openings — horizontal sliders, single-hungs, and picture windows common in manufactured housing.
Energy-Efficient Glass
Double-pane options that reduce heat transfer and cut down on the hot-wall effect in summer rooms.
Proper Sealing & Flashing
Windows installed with correct flashing and sealant so water does not find its way behind the siding.
Trim & Finish Work
Interior and exterior trim finished cleanly so the new window looks like it belongs, not like a patch.
Door & Slider Coordination
Sliding glass doors and entry doors replaced alongside windows when the whole opening needs updating.
Remodel Integration
Windows replaced as part of a kitchen, bath, or sun room project so openings, plumbing, and finishes are handled together.
Why It Matters
The Wrong Window Causes More Problems Than It Solves
A window that does not fit the manufactured opening precisely will leak, draft, and stress the siding around it. Standard residential windows are often the wrong depth and flange configuration for a mobile home wall, which is why a specialist matters.
Cal Star has replaced windows on manufactured homes across Southern California — including during full kitchen and bath remodels where the opening, the plumbing, and the interior finish all need to line up. We measure carefully, install to the home's construction, and stand behind the work.

FAQ
Windows Questions, Answered
Can you replace windows in a mobile home?
Yes. Manufactured home windows come in specific sizes and configurations. We source units that fit your openings and install them correctly.
Will new windows really help with heat?
Often noticeably. Replacing single-pane glass with insulated double-pane units reduces the heat that transfers through the wall, especially on west- and south-facing windows.
Can window replacement be part of a remodel?
Yes, and it usually should be when the opening is already being worked on. Kitchen and bath remodels are common times to update windows at the same time.
Do you handle the warranty if a window is damaged?
We work with homeowners through manufacturer warranty claims when a defective unit needs replacement after installation.
