Fast, Reliable Custom Windows & Doors Across Pasadena
Custom windows and doors in Pasadena are not a simple swap-out job. The city sits at the foot of the San Gabriel Mountains, recording summer temperatures above 100°F with a regularity that makes glazing choices structural, not decorative. And large portions of Pasadena’s housing stock date from 1900 to 1940, which means many openings were framed for single-pane wood sashes and mortised door jambs that big-box replacement units simply will not fit. We know this because we work these streets. If you are in Pasadena and need a custom window or door measured, specified, ordered, and set true, call (888) 635-0804. A live person answers, any hour.
Why TruePane Windows & Doors Is Pasadena’s Preferred Custom Windows & Doors Company
Dale Kessler founded TruePane on a rule that still hangs in the shop: if the pane is not true, the job is not done. That standard carries through every custom order we handle in Pasadena, from a single arched window in a Spanish Colonial Revival off Orange Grove Boulevard to full curtain wall packages in commercial storefronts near Colorado Boulevard. We are an authorized installer for more than a dozen manufacturer lines, including, PGT, and CGI, and we quote those lines side by side on paper so you can see exactly what you are buying and what it costs before any order is placed.
What does that mean for a Pasadena homeowner? It means the person measuring your opening in the 91101 zip code is background-checked and uniformed, and that person measures twice. It means both warranty layers, the manufacturer’s and ours, are registered in writing before our truck leaves your driveway. We carry a Done Right Promise on every custom job. If something is not right, we return and make it right. No paperwork fight. No fine print that covers neither.
We have also learned to work the city’s approval process, not against it. Pasadena’s Design Review requirements trip up plenty of out-of-town contractors. Our crews have submitted and passed historic-preservation reviews in Bungalow Heaven, and we can tell you before you order whether your window specification will survive the hearing or get bounced back for redesign. That local knowledge is not a marketing line. It saves you weeks and permit fees.
Our Custom Windows & Doors Services in Pasadena
Every custom window and door project is a chain of decisions, and each link has to hold or the whole thing fails. Here is how we handle the work in Pasadena specifically. And if you want the fuller picture of what a custom order involves, our Custom Windows & Doors team walks through the process step by step.
Architectural Grilles & SDLs
In Pasadena, grilles are not a cosmetics conversation. Bungalow Heaven’s landmark ordinance mandates true divided lights on Craftsman homes. That means the sash bars must physically separate individual glass lites, not imitate them with a snap-in grid over a single pane. We specify wood or aluminum-clad wood units whose bar profiles match the original sash dimensions on file with the city. Order the wrong profile and Design Review will flag sightline drift even after an approval. We get the specification right the first time.

Custom Shape Windows
Spanish Colonial Revival and Mediterranean Revival homes in Pasadena regularly feature round-top, arch, and eyebrow windows that off-the-shelf manufacturers do not catalog. Our shop orders these as custom radius units, templated from the actual rough opening rather than a standard arc. That matters in older Pasadena homes where settling over a century has left openings that are no longer perfectly square. A traced template handles the irregularity. A factory default radius does not.

Oversized Glass Panels
Pasadena hillside homes built to capture San Gabriel Mountain views often call for glass panels that exceed standard glazing sizes. These units need thicker glass, heavier frames, and sometimes tempered specifications depending on proximity to the Very High Fire Hazard Severity Zone in the northern foothills. We specify the laminate and low-E stack to handle both the view and the afternoon solar gain that hits east- and west-facing elevations hard in summer. The goal is a window that frames the mountains without turning the living room into an oven.

Commercial Storefront Glazing
For storefront work along Colorado Boulevard and Lake Avenue, the constraints are different but no less exacting. Landlords and the city both have standards, and a storefront down for a week is lost revenue. We install commercial storefront glazing and curtain wall systems with clear schedules and fixed written pricing, including for jobs that require after-hours coordination or fire-rated glass in mixed-use buildings. Most commercial Pasadena work we handle is quoted as a single line item with a defined lead time, not a series of change orders.

Trusted Brands We Service in Pasadena
We install and service custom windows and doors from more than a dozen manufacturers, and in Pasadena we lean heavily on Marvin for true divided-light Craftsman work, Andersen for clad-wood replacements in larger Spanish Revival homes, and CGI for impact-rated units in foothill fire zones. We keep relationships with ES Windows and ECO Window Systems for specialty profiles and oversized lites. Because we quote these brands side by side on paper, you can compare frame material, glazing packages, and warranty durations line by line before you commit. That is the square deal, and it is how every Pasadena bid leaves our office.
Common Custom Windows & Doors Problems We See in Pasadena Homes
After years of custom window and door work across Pasadena, certain failures repeat. Here are the ones we see most often in this city’s housing stock.
- Simulated divided-light windows flagged by Design Review. A homeowner or contractor installs a vinyl unit with SDL grids, and Bungalow Heaven’s preservation staff rejects it outright. The fix is a true divided-light wood or clad-wood unit matching the original Craftsman sash profile, and the reorder adds weeks.
- Missing Title 24 documentation on custom glazing. California’s energy code applies to replacement windows even in historic districts. Skip the compliance paperwork on a custom wood order and final inspection fails, which can delay occupancy by two months.
- Fogged seals in original single-pane-to-insulated conversions. Homes off N. Michigan Avenue and around the Arroyo Seco that received early retrofits often have failed insulated glass units now showing condensation between panes. The seal is gone, the argon has leaked, and the unit needs replacement, not a wipe-down.
- Off-the-shelf units that do not match the original sash profile. In older Pasadena homes near San Marino and South Pasadena, a standard-width frame changes the sightline enough that the window reads as a patch, not a replacement. Historic-preservation officers notice, and so do neighbors.
Pricing for Custom Windows & Doors in Pasadena, CA
Custom window and door pricing in Pasadena runs higher than in neighboring tract-home markets because the work is fundamentally different. A true divided-light Marvin clad-wood double-hung sized to a Craftsman opening in Bungalow Heaven typically runs $1,800 to $3,200 per window, installed, depending on glazing package and permitting complexity. Custom shape windows, arches and round-tops in Spanish Revival homes, run $2,400 to $5,000 per unit. Oversized glass panels for hillside view walls start around $4,500 and can exceed $12,000 depending on size, glass thickness, and fire-zone requirements. Architectural grilles and SDLs add $250 to $700 per window depending on bar profile and true divided-light construction. The design review submittal itself usually adds three to five weeks to the schedule, not in labor but in paperwork and lead time. Our fixed written price is set before we order. Lead times on custom units often stretch past twelve weeks, and ordering after the project starts means rush fees. We write the price down before the long-lead order so the number does not move.

FAQs - Custom Windows & Doors in Pasadena
Yes. Bungalow Heaven’s preservation ordinance requires true divided-light wood or aluminum-clad wood sashes matching the original Craftsman profile, and Design Review staff automatically reject any submittal using vinyl frames or simulated divided lights. The rejection typically costs three to five weeks in redesign and re-permitting. We handle this by specifying true divided-light units from the start and submitting dimensions matched to the original sash profile on file with the city. Call (888) 635-0804 before you order anything, and we will tell you if your spec will pass.
Plan on three to five additional weeks for any custom window or door job in a Pasadena Historic Landmark District. The Design Review submittal and approval cycle runs before the manufacturer even accepts the order, and custom true divided-light units routinely carry factory lead times of twelve weeks or more. In Arcadia or Temple City, the same window would skip the preservation review entirely. We build that added time into the schedule up front so you are not surprised when week three arrives and the windows have not shipped yet.
Yes, in two ways. Title 24 sets minimum low-E glazing standards for replacement windows throughout Pasadena, and homes within the designated Very High Fire Hazard Severity Zone in the northern foothills may additionally require tempered or fire-rated glass and non-combustible door and frame materials. The exact specification depends on your parcel’s fire-zone designation and the window’s distance from grade. We document the glazing package for final inspection so there is no reorder at the end of the job.
Fog between panes means the insulated glass seal has failed, the argon or krypton fill has leaked out, and the unit’s insulating value is gone. On a classic Pasadena bungalow or Spanish Revival home, a fogged replacement unit usually means the original retrofit used a low-bid insulated glass package that has now failed. The repair is a full replacement of the insulated glass unit, matched to the frame’s existing sightline so the window still reads correctly against the home’s architecture. Call (888) 635-0804 and we will quote the replacement at your existing frame, not force a whole-window swap if the sash is sound.
For Spanish Colonial Revival and Mediterranean Revival homes, the windows that look right and perform well are typically wood or clad-wood casements, arched fixed units, and multi-lite double-hungs with true divided lights in narrow profiles. These homes were built with deep stucco reveals and masonry openings, so the window should sit within the wall plane rather than proud of it. We specify units that match the original trim depth and muntin bar thickness, then add a low-E glazing package to handle Pasadena’s summer heat without changing the window’s exterior appearance. The result is a window that looks original and performs like a modern unit.
