AfterFast, Reliable Window Installation Across Hillsborough
Window installation in Hillsborough is not a standard replacement job. The town’s housing stock runs to architecturally significant estate homes from the 1920s through 1960s, and most window work here requires Design Review Commission sign-off before a permit is even issued. TruePane Windows & Doors has navigated that process for Hillsborough homeowners for years, because Window Installation on true divided-light wood windows and original steel casements is what our crews do every week. If you’re planning replacement windows on a Spanish Colonial, Mediterranean, or Tudor home in Hillsborough, call (888) 635-0804. We’ll walk you through the schedule, the drawings, and the written price before anything gets ordered.
Why TruePane Windows & Doors Is Hillsborough’s Preferred Window Installation Company
Hillsborough homeowners tend to ask the same three questions before they sign anything: does the installer understand the Design Review process, will the new windows match the original profiles, and will the company still answer the phone in ten years if a seal fails. We answer all three in writing. Dale Kessler founded TruePane in 2008 on a rule that has not changed: if the pane is not true, the job is not done. Our technicians measure every opening twice, quote manufacturer lines side by side on paper, and register both warranty layers before the truck leaves the driveway. No fine print that covers neither.
We serve Hillsborough with background-checked, uniformed crews who understand what a 1930s Tudor or a 1920s Mediterranean home demands. This is not a market where you swap in a standard vinyl double-hung and call it a day. The Town’s Design Review Commission will catch a mismatched muntin profile, and the homeowner pays for it in weeks of resubmittals. We coordinate stamped architectural drawings, match grille patterns to the original, and get the package through review without a second trip to the board. That local knowledge is the difference between a clean install and a project that drags into the next season.

Our Window Installation Services in Hillsborough
Casement Windows
Hillsborough’s original steel casement windows are a signature of the town’s Spanish Colonial and Mediterranean estates from the 1920s and 1930s. The problem is the hillside fog belt that pushes marine moisture up the Peninsula slopes. Steel frames corrode faster here than in fog-shielded inland towns, and the operable sash seizes. By the time a homeowner calls us, reglazing is usually not an option. We replace those casements with period-matched steel or with thermally broken aluminum or wood casements that replicate the original sightlines. The Design Review package lists the muntin profile, the finish, and the hardware style before we order a single unit.
Awning Windows
Awning windows show up frequently over kitchen counters and in bathroom openings on Hillsborough’s older estate homes. The original wood frames take on moisture from the marine fog that settles on hillside properties from Chateau Drive up toward the higher ridges. Fog-driven moisture accelerates rot along the bottom rails. We replace those awnings with custom-milled wood or fiberglass units that match the original profile, and we flash the opening so the next sixty years of fog does not find its way behind the frame.
Fixed & Picture Windows
Large fixed windows and picture windows on Hillsborough estate homes are usually where the architectural statement lives. A wide arched picture window on a Mediterranean facade, or a bank of fixed true divided-light windows on a Tudor’s gable end, sets the character of the front elevation. We build these as custom units with Douglas fir or mahogany, low-E glass, and argon fill, matched to the original grille pattern. The town’s Design Review Commission looks at these first, so our team prepares the stamped drawings and the material schedule before the commission meets.
Single & Double Hung Windows
Double-hung windows are common on Hillsborough’s Colonial and shingle-style estates, and the original wood sashes fail in predictable ways. On a 1930s Tudor estate off Chateau Drive, our crew pulled the original true divided-light double-hung windows and found the oak sashes rotted along the bottom rails from years of fog-driven moisture. We replicated the original profiles in custom Douglas fir with low-E glass and argon fill, matched the original bronze hardware, and coordinated the stamped drawings with the owner’s architect so the Design Review package went through without a resubmittal. That is the work we do regularly in Hillsborough.
We also handle Sliding Windows, Bay & Bow Windows, and Garden & Basement Windows. Every job starts with a written line-item quote and ends with both manufacturer warranty layers registered in writing.

Common Window Installation Problems We See in Hillsborough Homes
- Corroded steel casement frames. Hillsborough’s hillside fog belt pushes marine moisture up the slopes from the Bay, and the original steel casement frames on 1920s and 1930s estates corrode faster than they do in fog-shielded towns. The operable sash seizes, and the only fix is full replacement with period-matched steel or thermally broken units.
- Design Review rejections over muntin profiles. Architects submit window designs that fail Design Review because the muntin profiles don’t match the original Spanish Colonial grille pattern. That mistake costs weeks of lead time. We coordinate the drawings with the architect before the package goes to the board.
- Hidden rot behind unflashed steel openings. Moisture trapped behind unflashed steel window openings rots the rough framing, and it stays hidden until the sashes are pulled for replacement. We open the wall, inspect the framing, and repair or sister the affected wood before setting the new unit.
- Fogged seals on true divided-light glass. Hillsborough homeowners with original true divided-light windows often assume the fogging is condensation. Seal failure on vintage insulated glass is common here, and replacement means matching the original muntin bars and glass profile so the window still reads as original.
Pricing for Window Installation in Hillsborough, CA
Window installation in Hillsborough runs higher than the Peninsula average because the work is custom. A period-matched custom casement window on a Spanish Colonial estate typically runs $1,800 to $3,400 per unit depending on glass package, finish, and hardware. A custom true divided-light double-hung in Douglas fir generally falls between $2,200 and $4,200 per window. Fixed picture windows with arched tops and custom grille patterns run $2,500 to $5,500, and bay or bow assemblies with matching roof work start around $9,000 and climb from there. What drives the price: the drawings and Design Review package, the millwork quality, the glass spec, and whether the rough framing needs repair once the sashes come out. We give you a fixed written quote before ordering anything. Call (888) 635-0804 for a free estimate and we’ll put the numbers on paper.
Lead times, not labor, set the calendar on this tier. Custom millwork takes eight to twelve weeks from order to delivery, and the Design Review package adds its own schedule. We tell you that on the first visit. There is no surprise later.

FAQs - Window Installation in Hillsborough
Yes, in most cases. Hillsborough’s Design Review Commission requires that any window or door replacement on older estate homes maintain the original architectural character, and most projects need stamped architectural drawings and board sign-off before a building permit is issued. This applies even when you’re matching the existing sizes and styles exactly. Neighboring cities like Burlingame or San Mateo don’t require this step. Call (888) 635-0804 and we’ll help you understand what your specific project needs before you spend money on drawings.
Sometimes you can, but in Hillsborough the steel frames themselves are usually the problem. The hillside fog belt corrodes the original steel casement frames from the inside out, and by the time the glass fails the operable sash has already seized. If the frame is sound, reglazing is possible. If the stems are rusted through, the window needs full replacement with period-matched steel or thermally broken aluminum. We’ll tell you which is which when we inspect the opening. Estimates are free.
Hillsborough architects commonly specify PGT and CGI for impact-rated installations and ES Windows for custom steel and thermally broken aluminum work that matches original Spanish Colonial and Mediterranean details. TruePane is an authorized installer for all three, along with. We quote manufacturer lines side by side on paper so you see the actual numbers. Call (888) 635-0804 for a written quote.
If the fog is between the glass panes and does not wipe away, it’s a failed seal. If the fog is on the room-side surface of the glass, it’s condensation from indoor humidity. In Hillsborough’s hillside climate, both happen, but seal failure on vintage insulated glass is common because the original units were never designed for sixty years of fog-driven moisture. We inspect the sash and confirm which one you’re dealing with before recommending repair or replacement. Call (888) 635-0804 and we’ll take a look.
Most Hillsborough stucco estate homes have wall thicknesses between 8 and 10 inches, which means the replacement window jamb depth runs 6-9/16 to 7-1/2 inches depending on the original framing and the plaster build-out. Custom millwork is usually required because off-the-shelf units will not hit the right reveal. We measure every opening twice and order the jamb depth to match the existing wall so the new window sits flush with the original trim. Call (888) 635-0804 for a free measurement.
