Quick Answer
Mobile home window replacement costs $150–$800 per window installed, roughly 30–50% less than site-built home windows due to smaller standard sizes and simpler installation methods. Most manufactured homes use specific rough opening sizes (30”×60”, 36”×48”, 48”×48”) with flange-mount frames that slot directly into siding. Upgrading from single-pane aluminum to double-pane vinyl windows can reduce heating and cooling costs by 20–40% — a critical improvement for the 8.3 million manufactured homes in the US where energy costs consume a disproportionate share of household income.
Key Takeaways
- Average cost: $150–$800 per window (installed), with a typical single-wide home (8–10 windows) costing $1,200–$8,000 total
- Standard mobile home window sizes differ from site-built homes: common sizes include 30”×60”, 36”×48”, 48”×48”, and 54”×76” — not the standard 24”×36”, 30”×48”, 36”×60” sizes found at big-box stores
- HUD Title VI standards govern manufactured home window requirements including minimum egress, ventilation, and energy performance — windows must meet HUD Zone-specific U-factor requirements
- Top brands: Silver Line (Andersen), Simonton, Ply Gem, and MI Windows manufacture windows specifically for mobile homes with proper flange dimensions
- DIY installation is more feasible for mobile homes than site-built homes: flange-mount windows are designed for homeowner installation, saving $75–$200 per window in labor
- Energy savings of 20–40% are achievable when replacing 1990s-era single-pane aluminum windows with modern double-pane vinyl units with Low-E coating
Why Mobile Home Window Replacement Is Different
Manufactured homes are built to the HUD Code (Part 3280), not local building codes. This federal standard governs every aspect of construction, including window specifications. Unlike site-built homes where windows are sourced from local suppliers with regional sizing, manufactured homes use standardized window dimensions optimized for factory production and transportation.
Key Structural Differences
| Feature | Mobile/Manufactured Home | Site-Built Home |
|---|---|---|
| Window frame type | Flange-mount (nail fin integrated) | Box frame or flange-mount |
| Wall thickness | 2”×4” or 2”×6” (often thinner overall) | 2”×4” or 2”×6” standard |
| Rough opening | Specific to HUD standard sizes | Customizable on-site |
| Exterior finish | Vinyl siding, T1-11, or metal | Brick, stucco, wood, vinyl |
| Installation method | Window slides into pre-cut opening, flange nailed to sheathing | Window shimmed, leveled, insulated, flange or fin attached |
| Permit required | Usually no (HUD preempts local code) | Often yes |
| Typical window count | 8–14 (single-wide), 14–22 (double-wide) | 15–30+ |
HUD Code Window Requirements
The HUD Code (24 CFR 3280) sets specific requirements for manufactured home windows:
- Minimum egress: At least one window per bedroom with minimum 5.0 sq ft clear opening (ground floor) or 5.7 sq ft (upper floors)
- Minimum glazed area: 8% of floor area for habitable rooms
- Minimum ventilation: 4% of floor area as operable ventilation
- Wind zone ratings: Wind Zone 1 (standard), Wind Zone 2 (up to 100 mph), Wind Zone 3 (up to 110 mph) for coastal areas
- Thermal performance: U-factor requirements vary by HUD Climate Zone (Zones 1–3)
- Safety glazing: Tempered glass required in doors, tub/shower enclosures, and within 24” of door openings
Standard Mobile Home Window Sizes
One of the biggest mistakes homeowners make is ordering standard site-built home windows from Home Depot or Lowe’s. Mobile home windows use different rough opening dimensions. Here are the most common sizes:
Single-Hung Mobile Home Windows
| Size (W×H) | Typical Location | Price Range (Vinyl) |
|---|---|---|
| 28”×38” | Bathroom, small bedroom | $120–$280 |
| 30”×48” | Bedroom, kitchen | $140–$340 |
| 30”×60” | Living room, master bedroom | $160–$400 |
| 36”×48” | Bedroom, dining area | $150–$360 |
| 36”×54” | Living room | $170–$420 |
| 48”×48” | Large living area | $200–$500 |
Sliding Mobile Home Windows
| Size (W×H) | Typical Location | Price Range (Vinyl) |
|---|---|---|
| 36”×24” | Bathroom, laundry | $110–$260 |
| 48”×36” | Kitchen, bedroom | $140–$350 |
| 60”×36” | Living room, dining | $170–$440 |
| 72”×36” | Large living area | $200–$540 |
| 72”×48” | Great room, sliding door adjacent | $240–$650 |
How to Measure Your Mobile Home Windows
- Measure the rough opening, not the existing window frame: Remove interior trim to expose the framed opening in the wall
- Measure width first, then height: Record to the nearest 1/8 inch
- Measure from inside the home: Width = left-to-right, Height = top-to-bottom
- Order windows 1/4” smaller than the rough opening to allow for shimming and insulation
- Identify the flange type: Most mobile homes use an exterior nailing fin (flange) that sits against the sheathing
Pro tip: The model number of your existing windows is often printed on a metal or plastic label inside the frame track. This label includes the manufacturer and exact size, making replacement ordering much easier.

DIY vs Professional Installation
Mobile home window replacement is generally more DIY-friendly than site-built home window replacement. The flange-mount design and lighter wall construction make the process straightforward for homeowners with basic tools.
When DIY Makes Sense
- Your home has standard vinyl siding or T1-11 plywood exterior
- Windows are easily accessible (ground floor, no scaffolding needed)
- You’re replacing same-size windows (no rough opening modification)
- You have basic tools: drill, level, utility knife, caulking gun, pry bar
- Budget is tight (save $75–$200 per window in labor)
DIY Installation Steps (Overview)
- Remove interior trim carefully to expose the window frame
- Score the exterior caulk line with a utility knife where the window flange meets the siding
- Cut siding if necessary (for J-channel removal) — use a zip tool to release vinyl siding
- Remove old window: Unscrew flange screws, pry window out from exterior
- Clean and inspect rough opening: Replace any rotted wood, check for level
- Install new window: Apply flashing tape to sill, insert window from exterior, ensure flange sits flush against sheathing
- Secure window: Drive screws through flange into wall framing every 8–12 inches
- Insulate gaps: Fill any gaps between window frame and rough opening with low-expansion foam
- Apply exterior sealant: Run a bead of exterior-grade caulk around the entire flange perimeter
- Reinstall siding and interior trim
When to Hire a Professional
- Your home has aluminum or steel siding (difficult to cut and reseal)
- Windows are on a second story or require a ladder over 8 feet
- You need custom sizes that require modifying the rough opening
- Water damage is present around existing windows (needs professional assessment)
- Your home is in Wind Zone 2 or 3 (stricter installation requirements)

Energy Savings: Mobile Home Window Upgrade Impact
Manufactured homes built before 2000 typically have single-pane aluminum windows — among the least efficient windows in US housing stock. Upgrading to modern double-pane vinyl windows with Low-E coating delivers substantial energy savings.
Before-and-After Energy Comparison
| Window Type | U-Factor | SHGC | Annual Heating Cost (Zone 4) | Annual Cooling Cost (Zone 2) | Total Annual Energy Cost |
|---|---|---|---|---|---|
| Single-pane aluminum (pre-2000) | 1.10–1.30 | 0.80+ | $680–$1,100 | $420–$720 | $1,100–$1,820 |
| Single-pane aluminum with storm | 0.80–0.95 | 0.65–0.75 | $520–$850 | $340–$580 | $860–$1,430 |
| Double-pane aluminum (2000–2010) | 0.55–0.65 | 0.55–0.65 | $380–$620 | $260–$440 | $640–$1,060 |
| Double-pane vinyl (standard) | 0.30–0.35 | 0.35–0.45 | $240–$400 | $170–$290 | $410–$690 |
| Double-pane vinyl (Low-E, argon) | 0.22–0.28 | 0.25–0.35 | $190–$330 | $140–$240 | $330–$570 |
| Triple-pane vinyl (premium) | 0.15–0.20 | 0.20–0.30 | $150–$260 | $110–$200 | $260–$460 |
Estimates based on 1,200 sq ft manufactured home with 12 windows, 2026 average energy rates ($0.16/kWh electricity, $1.40/therm gas). See our Energy Savings Assumptions for Window ROI Models for methodology.

Common Mobile Home Window Problems
1. Jalousie Windows (Slatted Glass)
Found in pre-1990 mobile homes, jalousie windows consist of horizontal glass slats that crank open. They are extremely inefficient (effectively single-pane with gaps between slats) and difficult to seal.
Solution: Replace entire unit with a sliding or single-hung vinyl window. The rough opening is typically standard mobile home size. Cost: $200–$500 per opening.
2. Failed Seals on Double-Pane Windows
Cloudy or foggy glass indicates seal failure, allowing moisture between panes and eliminating the insulating gas fill.
Solution: If the frame is in good condition, glass replacement may be possible ($100–$250 per sash). Otherwise, full window replacement ($200–$500). See our Window Glass Replacement Cost 2026 Guide for details.
3. Aluminum Frame Corrosion
Coastal mobile homes often experience aluminum frame pitting and corrosion from salt air, leading to operational issues and air infiltration.
Solution: Replace with vinyl-framed windows (immune to salt corrosion). Cost: $200–$500 per window installed.
4. Water Leaks Around Window Frame
Often caused by failed exterior caulk, damaged flange, or improper original installation allowing water behind siding.
Solution: Remove window, inspect and repair substrate/flashing, reinstall with new sealant and flashing tape. Cost: $150–$600 per window (depending on substrate damage).
5. Drafty, Hard-to-Operate Windows
Single-pane aluminum sliding windows in older mobile homes often develop worn tracks, making them difficult to open and creating significant air leaks.
Solution: Replace with new vinyl sliding or single-hung windows. Cost: $150–$400 per window.
Seasonal Considerations for Mobile Home Window Replacement
Best time: Spring (April–May) and fall (September–October) offer moderate temperatures, lower contractor demand, and potential off-season discounts.
Summer replacement: Feasible but plan for temporary loss of AC in affected rooms. Work early morning to avoid heat exposure.
Winter replacement: Not recommended in cold climates — temporary exposure can freeze pipes in mobile homes with minimal insulation. If unavoidable, do one window at a time and seal immediately.

Frequently Asked Questions
How much does it cost to replace all windows in a single-wide mobile home?
Replacing all windows in a typical single-wide mobile home (8–10 windows) costs $1,200–$8,000 depending on window material and whether you DIY or hire a contractor. Budget vinyl double-pane windows installed DIY run $1,200–$3,000, while professionally installed Low-E vinyl windows cost $3,000–$6,000. Upgrading to fiberglass windows pushes the total to $4,500–$8,000.
Are mobile home windows different from regular house windows?
Yes, mobile home windows use different standard sizes (e.g., 30”×60”, 36”×48”, 48”×48”) than site-built home windows. They also use a flange-mount installation system designed for thinner manufactured home walls. Standard big-box store windows often won’t fit mobile home rough openings without modification. Always order from manufacturers that produce HUD-standard sizes like Silver Line, Simonton, or Kinro.
Can I install mobile home windows myself?
Yes, mobile home window replacement is one of the most DIY-friendly home improvement projects. The flange-mount design allows homeowners with basic tools to remove and install windows in 1–2 hours each. DIY installation saves $75–$200 per window in labor costs. However, hire a professional for second-story windows, aluminum/steel siding homes, or when water damage is present.
What size are standard mobile home replacement windows?
Common mobile home window sizes include 28”×38”, 30”×48”, 30”×60”, 36”×48”, 36”×54”, 48”×48”, 54”×76” for single-hung, and 36”×24”, 48”×36”, 60”×36”, 72”×36” for sliding windows. Always measure the rough opening (not the visible window) before ordering replacements, and order 1/4” smaller than the opening for proper shimming.
Do mobile home window replacements qualify for tax credits?
Yes, energy-efficient mobile home window replacements can qualify for the federal 25C tax credit (30% of costs up to $600) if the windows meet Energy Star or NFRC performance requirements. Additionally, many states and utility companies offer rebates of $25–$500 per window. HUD code homes are eligible for the same federal tax credits as site-built homes.
Which mobile home window brands are best for hurricane zones?
For manufactured homes in Florida, Gulf Coast, and other Wind Zone 2–3 areas, Prime Window Systems and Simonton StormBreaker lines offer impact-resistant glass rated for winds up to 110+ mph. These windows include laminated glass (similar to windshields) that stays intact even when struck by flying debris. Expect to pay 20–40% more than standard windows, but insurance wind mitigation discounts can offset much of the cost.
How long do mobile home replacement windows last?
Quality vinyl double-pane mobile home windows typically last 20–30 years with proper maintenance. Fiberglass windows last 30–50 years. Budget aluminum windows may need replacement in 15–20 years. Key factors affecting lifespan include climate exposure, installation quality, and whether the home is level (unlevel homes stress window frames). Look for windows with at least a 10-year glass seal warranty.
Can I replace my mobile home windows with larger ones?
Enlarging mobile home window openings is more complex than in site-built homes because manufactured home walls are load-bearing along specific stud paths. Enlargement requires structural engineering review and may violate HUD Code certifications. In most cases, it’s safer and more cost-effective to replace windows with the same size. If you must enlarge, consult a licensed contractor experienced with manufactured housing structural modifications.
