What Window Problems Do Pasadena Homes Face?
Summer heat, Santa Ana winds, and aging wood windows cause most window trouble in Pasadena.
01
Why Do Pasadena’s Summer Heat and West Sun Overwork Old Windows?
Pasadena averages a high of 91.3°F in August, based on NOAA climate normals. Single-pane glass lets that heat pour into west-facing rooms. The AC runs longer and furniture near the glass fades.
02
Why Do Santa Ana Winds From the San Gabriels Rattle and Leak Old Sashes?
Santa Ana winds race down the San Gabriel Mountains into north Pasadena. NOAA reported a 99 mph gust near Altadena in January 2025. Loose sashes rattle, dust blows through gaps and cracked putty lets glass shift.
03
Why Do So Many Pasadena Craftsman Homes Still Have Original Wood Windows?
Pasadena’s landmark districts are full of Craftsman bungalows with their first wood sashes. Those windows define the look of the house. In a landmark district, replacing them takes city approval, so many owners restore instead.
Window Repair in Pasadena
Many Pasadena windows need a repair, not a new window. Angi puts the average window repair in Los Angeles at $284.
In Bungalow Heaven and Madison Heights, contractors fix broken sash cords, painted-shut sashes and loose glass. In Hastings Ranch and Lamanda Park, it’s worn slider rollers, stripped casement cranks and dry weatherstripping.
You get a written price for each window. If one can’t be saved, contractors tell you why. See our window repair service.
Historic Window Restoration in Pasadena
Pasadena has 23 landmark districts, and Bungalow Heaven, designated in 1989, is the best known. Street-facing window changes there need a Certificate of Appropriateness before the city issues a permit.
Like-for-like windows get a staff review. Changing two or more features, such as frame material and grille pattern, goes to the Historic Preservation Commission.
Restoring is the easiest path. Contractors free painted sashes, restring cords, repair rot and reglaze with fresh putty. For steel windows in Spanish Revival homes, see our steel casement window restoration page.
Homes built before 1978 need lead-safe work under EPA rules. See our historic window restoration service.
Window Glass Replacement in Pasadena
If the frame is sound, contractors replace only the glass and keep the window. Angi puts the national average at $285 per window.
Hot summers wear out dual-pane seals, and the glass fogs between the panes. See our foggy window repair service.
On hot west walls, low-E glass cuts the heat that gets through. Glass near doors and tubs must be safety glass, and contractors check every spot before ordering.
Retrofit Windows in Pasadena
For stucco homes in Hastings Ranch and east Pasadena, retrofit windows are the fastest upgrade. The new window fits inside the old frame, so your stucco and plaster stay untouched.
Pasadena requires every new window to meet the California Energy Code. For replacement windows, that means a U-factor of 0.30 or lower, shown on the NFRC label.
Craftsman homes look best with double-hung windows that match the original style. See our double-hung window replacement page.
Window Installation in Pasadena
Adding a kitchen window, enlarging a bedroom window, or building an ADU is new installation. The opening needs a header, flashing and a permit, plus historic review in a landmark district.
Contractors frame the opening, flash it in the right order, and patch the stucco or siding to match. See our window installation page.
Emergency Window Repair in Pasadena
A branch through a window in a Santa Ana wind or a break-in off Colorado Boulevard can’t wait. Contractors board the opening, clean up the glass, and check the lock.
Angi puts a plywood board-up at $360 per window in California. See our emergency window repair service.
Window Screen Replacement in Pasadena
Summer heat turns fiberglass mesh brittle, and wind rips old screens from their frames. Contractors rescreen straight frames and build custom screens for casements, sliders, and patio doors.
Wood screens on historic homes can be rebuilt to match. See our window screen replacement service.
How Much Does Window Replacement Cost in Pasadena?
A whole-house job in Los Angeles averages $19,356, and most homeowners pay $16,359 to $22,377, according to Angi.
| Pasadena cost factor | Who it affects |
|---|---|
| Building permit | Every window change-out |
| Certificate of Appropriateness | Street-facing work in landmark districts |
| Lead-safe work | Homes built before 1978 |

Pasadena Water and Power has no window rebate right now. Its free Home Improvement Program does cover weather stripping and air sealing. See our pricing page.
Do You Need a Permit for New Windows in Pasadena?
Yes. Window replacement isn’t on the city’s permit-exempt list, so you file with Building and Safety at the Permit Center, (626) 744-4200.
- Plans: the city’s Window and Door Replacement sample plan shows each window and if the home sits in a fire zone.
- Energy code: every new window must meet the California Energy Code.
- Historic homes: get a Certificate of Appropriateness first for street-facing work.
- Small jobs: simple permits can be reviewed over the counter in as little as 5 to 10 minutes.

Pasadena Window Replacement FAQs
Can You Replace Windows in Bungalow Heaven or Another Landmark District?
Yes, with approval. Street-facing replacements need a Certificate of Appropriateness. Bungalow Heaven also has its own conservation plan.
Can the Mills Act Help Pay for Window Work on a Historic Home?
Yes, for eligible homes. Pasadena says owners who see savings under the Mills Act average a 51% cut in property taxes, and window repair counts as qualifying work.
Is Lead Paint a Concern on Older Pasadena Windows?
Yes. About 72% of Pasadena homes were built before 1980, and old sashes carry many layers of paint. Certified renovators must seal the work area and clean up with HEPA vacuums.
Which Windows Keep Pasadena Homes Coolest in Summer?
Dual-pane windows with low-E glass keep the most heat out. Start with west and south windows, since those take the afternoon sun.
