AfterWindow Company in Hillsborough, CA
Window and door work in Hillsborough typically costs between $850 and $4,200 per opening depending on the product line and the condition of the existing frame, with most single-window replacements landing in the $1,200 to $2,800 range installed. Hillsborough’s housing stock runs older and larger than most Bay Area suburbs, which means we see more custom sizing, more wood frame repair, and more permit review than a typical tract-home job. If you’re pricing a project, call (817) 686-2228 and we’ll put the real number on paper before anything gets ordered.
Why Hillsborough Homes Are Different
Hillsborough sits on the San Francisco Peninsula with a microclimate that shifts noticeably between the eastern flats near El Camino Real and the upper lots along Crystal Springs Road and Hayne Road. Fog and marine air sit on the western slope longer than homeowners expect, which means wood window frames and sills here take more moisture exposure than homes ten minutes east. We specify products accordingly: thermally broken aluminum or vinyl where the fog lingers, and heavier sealing protocols on any west-facing opening. Rot at the sill and frame corners is the most common call we get in Hillsborough, ahead of glass failure.
The housing stock itself changes what we order. A large share of Hillsborough homes were built between the 1920s and the 1970s, many with original single-pane sash windows and non-standard rough openings. That means fewer drop-in replacements and more measured, made-to-order work. Several neighborhoods also fall under Hillsborough’s design review process, which can require architectural approval before any exterior window or door change. We handle the paperwork and coordinate with the town, but homeowners should plan for review time on top of the installation itself.
Our Main Hillsborough Services
Most Hillsborough homeowners call us for one of two reasons: windows that have reached the end of their service life, or patio doors that no longer seal or slide properly. Each service has its own Hillsborough page with local pricing and the full job breakdown.
Window Replacement in Hillsborough
Replacement work in Hillsborough usually means pulling an older wood or aluminum frame, inspecting the rough opening for rot, and installing a properly flashed, sealed, and trimmed new unit. On homes with original sash windows, we often find the frame itself is salvageable but the balances and weatherstripping are gone. Full details, including which frame materials make sense on the fog-exposed west side of town, are on the Window Replacement in Hillsborough page.
Window Installation in Hillsborough
New-construction and addition window installation in Hillsborough runs into a different set of conditions: fresh framing, current building code, and often a builder or architect’s spec sheet. We work from the approved plans, set each unit to the manufacturer’s tolerance, and flash to the exact detail the Hillsborough inspector will check. The Window Installation in Hillsborough page covers the process, code requirements, and what the crew does and does not do on site.
Patio Door Installation in Hillsborough
Hillsborough homes with rear decks, pools, or garden exposures lean on patio doors more than most. A door that sticks, leaks, or lets fog-condensation into the track is a recurring problem here. We install sliding and hinged patio doors, level the track, and seal the threshold against the damp air that settles on the lower lots. See the Patio Door Installation in Hillsborough page for pricing and the specific door lines we carry.

What pushes a Hillsborough job higher is usually the frame. Original wood frames from the 1930s and 1940s frequently have hidden rot that only shows once the old unit comes out, and the town’s design review can add time on certain elevations. The price we quote is the price you pay: it goes on paper before any work starts, and it does not move at the door.

FAQs About Window Company in Hillsborough
Calls are answered by a live person around the clock, and scheduling is handled from our Bay Area office. Most Hillsborough consultations are booked within a few business days, with the written price delivered at that first visit. Call (817) 686-2228 to get on the schedule.
Many do. Hillsborough requires design review for exterior changes on a large portion of its housing stock, especially for visible elevations and non-standard products. We prepare and submit the documentation as part of the job, but permit review time sits outside our installation schedule. Call (817) 686-2228 and we can tell you whether your specific project triggers review.
No. The price goes on paper before any work begins, and it stays there unless you approve a written change order first. If the work fails within 365 days, we return and make it right at no charge under the Done Right Promise. That guarantee is in writing on every Hillsborough job.
