Most window and door work in Hillsborough is not a standard replacement job. The town’s large estate homes, many built between the 1920s and 1960s in Spanish Colonial, Mediterranean, and Tudor styles, regularly require period-matched custom work, and the Design Review Commission often has something to say about what goes in. We dispatch our own background-checked, uniformed technicians to Hillsborough from our Bay Area office, and a live person answers the phone at (888) 635-0804 whenever you call. If you’re weighing restoration against replacement on an older Hillsborough property, we can talk through what the Board will and won’t accept before you spend a dollar.

What to Look For in a Hillsborough Window & Door Contractor
Hillsborough is different from Burlingame or San Mateo, and not in a small way. A contractor can hand you a standard Andersen or Milgard catalog and quote the job in twenty minutes, but if the Board rejects the design, you’ve lost weeks and paid for drawings twice. We’d rather spend the first visit walking the house, measuring every opening twice, and pointing out exactly where the process gets complicated. Then we put manufacturer lines side by side on paper, with warranty durations in writing, so you can see what you’re buying before you commit.
What separates a good Hillsborough window contractor from an expensive lesson:
- Design Review experience. If the contractor has never filed with the Hillsborough Design Review Commission, you’re paying for their education.
- Warranty paperwork, not warranty promises. Both manufacturer warranty layers should be registered before the truck leaves the driveway, with durations stated in writing. We call this The Keystone Standard, and it’s non-negotiable on every job.
- Restoration instincts. Many Hillsborough homes have original steel casement windows and true divided-light wood windows. Knowing when to restore, when to replace in kind, and when a modern update will pass review is what you’re hiring.
- Straight pricing. A written, line-item quote means the bill looks like the estimate. No change orders, no surprise line items, no phone calls explaining why the number moved.
Dale Kessler, our founder, is a second-generation glazier, and the rule on his whiteboard has governed every job since 2008: if the pane is not true, the job is not done. We’ve carried that through more than years of combined craft heritage, and we stand behind every install with a Done Right Promise.
Windows & Doors Services We Offer in Hillsborough
Window Installation
New windows in Hillsborough often mean custom sizing for older openings that were never built to modern standard dimensions. We install Andersen, Pella, Marvin, Milgard, and more, and we register both manufacturer warranty layers before we leave the driveway. Learn more about our Window Installation in Hillsborough.
Door Installation
Hillsborough’s oversized arched doorways and thick masonry walls make door installation a custom craft here, not a stock-unit job. We handle period entries, interior doors, and hardware that matches the home’s original character. Learn more about our Door Installation in Hillsborough.
Window Replacement
Replacing fogged or rotted windows on a 1940s Hillsborough estate means matching sightlines, muntin profiles, and finishes that a 2020s tract home never required. We quote manufacturer lines side by side and help you choose what will clear Design Review. Learn more about our Window Replacement in Hillsborough.
Impact Windows & Doors
Coastal wind and hillside exposure make Impact Windows & Doors in Hillsborough a smart upgrade for many homes, especially along western ridges. We install PGT and CGI lines, both of which we’re authorized to carry, and both with written warranty registration.
Energy-Efficient Windows
Original steel casement and single-pane wood windows let Hillsborough’s afternoon marine fog turn into a heating bill. Energy-Efficient Windows in Hillsborough, with Low-E and double-pane upgrades done to match the home’s architectural character, reduce that loss without erasing the facade’s period identity.
Sliding & Patio Doors
Many Hillsborough estates were built before large-format glass doors existed, so retrofitting Sliding & Patio Doors in Hillsborough into a period home takes planning, sometimes stamped drawings, and framing work that respects the original structure. We handle the whole process, permit to final inspection.
Glass Railing Systems
For hillside terraces, pool decks, and balcony overlooks, Glass Railing Systems in Hillsborough keep the view uninterrupted. Hillsborough’s sloping lots make these installations structural work, not decorative add-ons, and we treat them that way.
Custom Windows & Doors
When the opening cannot accept a standard unit, we build it. Custom windows and doors are the largest share of our Hillsborough work, from true divided-light wood windows to oversized arched entry doors to curved glass where the elevation calls for it.
Neighborhoods We Serve in Hillsborough
Our technicians work regularly across Hillsborough, from the estate-lined streets near the Town Hall area to the larger hillside parcels off Hayne Road and the western ridges toward Interstate 280. Typical response time for a scheduled estimate in Hillsborough is same-week, and repairs can often be handled in a single visit.
- North Hillsborough, near the San Mateo Creek corridor
- The Hayne Road estates
- West Hillsborough, along the 280 corridor
- The Alpine Road corridor
Why Hillsborough’s Climate & Housing Affect Windows & Doors
Hillsborough’s position on the San Francisco Peninsula means the town catches afternoon marine fog rolling in off the Bay, and that moisture-laden air settles on the hillsides. The local failure patterns follow from it. Original steel casement hardware corrodes faster here than in more fog-shielded inland towns, and wood sills and frames on the 1920s through 1960s estates absorb moisture seasonally, swelling and shrinking until the paint splits and rot sets in. A window that looks weathered in Hillsborough is usually further along than the same window would be in Atherton.
The housing stock compounds it. These are not production-built suburban houses. Most are bespoke estate properties with original multi-pane steel casement or true divided-light wood windows, oversized arched doorways, and facade details that define the home. The Town’s Design Review Commission requires that any replacement maintain the original architectural character, which is why so much of the work in Hillsborough is custom restoration or period-matched replacement, not standard residential retrofitting. Contractors who don’t know this get caught at the permit stage, and the homeowner loses weeks. We plan for Design Review from the first visit, not after the order is placed.

FAQs About Windows & Doors in Hillsborough
Yes, in most cases. Hillsborough’s Design Review Commission requires that window and door replacements on older estate homes maintain the original architectural character, and on many properties that means stamped architectural drawings and board sign-off before a building permit is issued. We file these drawings as part of our Hillsborough work, and we build the lead time into the schedule from the start. Call (888) 635-0804 and we can tell you whether your specific house is likely to need Board review.
Most Hillsborough window replacements run $1,400 to $3,600 per unit for period-matched work, with whole-house packages considerably higher. The range depends on whether the home has original steel casements, true divided-light wood windows, or unusual opening sizes. We give a written, line-item quote after measuring, and it’s a fixed number, not an estimate that moves.
Yes, and this is the majority of our Hillsborough work. Matching original multi-pane steel casement or true divided-light wood windows means matching sightlines, muntin profiles, finish colors, and hardware placement, and we carry more than a dozen manufacturer lines including ES Windows and ECO Window Systems to make that match. If you want to see side-by-side quotes on paper before deciding, call (888) 635-0804 and we’ll prepare them.
No. The quote we hand you is the bill, unless the scope changes and you approve the change in writing first. That’s how Dale Kessler has run jobs since 2008, and it’s the only way we know how to work. No surprise line items, no change orders slipped in, no phone calls explaining why the number moved.
A straightforward replacement of a few windows can often be done in a single visit. A larger estate project with custom manufacturing and Design Review sign-off typically runs six to twelve weeks from order to final inspection, with the Board’s review schedule as the variable. We’ll lay out the full timeline in writing before you commit to anything.

What Hillsborough Customers Say
"French doors to the patio, custom size because this house was built in 1961 and nothing is standard. Measured twice, three weeks to fabricate like they warned, and the install day they laid runners over my floors without being asked."
- Marie S."Our bay window had rotted at the sill and two other outfits wanted to talk us into a flat picture window instead. TruePane rebuilt the opening and matched the original look. Neighbors have knocked on the door about it."
- Gene A."Two entry doors. Showed up when they said, second day was a half day like they said, and the painter they recommended confirmed the frames were dead plumb. The financing was explained in actual dollars, not a brochure."
- Janet R.
