Why Meridian Windows and Doors San Francisco Is Hillsborough’s Preferred Window Replacement Company
Hillsborough homeowners do not hand out trust freely. Too many have been burned by crews that quoted a number, showed up late, and left the trim caulk a mess. Our approach is different. Elliot Vance, who leads our team, runs every Hillsborough job to The Garrison Code: show up when promised, put the full price on paper before work begins, and do not move that number at the door. That’s why Hillsborough clients keep calling us back when the next wing of the house needs glazing.
We work on the mid-century estates that define Hillsborough’s architectural character. We regularly inspect floor-to-ceiling steel frames, oversized wood sashes, and custom divided-lite patterns that no stock window will ever match. Our technicians are background-checked and uniformed, so you know exactly who is walking through your gate. And when you call, a live person answers, 24 hours a day, every day of the year. No voicemail loops, no next-business-day callbacks.
Part of the Garrison Partners family, we have operated to The Garrison Standard since 2009. We do not chase volume. We spec the right product from eight manufacturer lines, including PGT, Therma-Tru, and ViewLux, not whatever happens to be on a warehouse shelf. If our work fails within 365 days, we return at no charge. That is written on every contract, in plain English.
Window Seal Repair in Hillsborough
Window seal repair in Hillsborough typically runs $180 – $620 per unit, depending on whether we are replacing the insulated glass unit in a wood sash or re-bedding a steel frame that has lost its glazing compound. A failed seal shows up as fog between the panes, condensation you cannot wipe away, or visible gaps where the glass meets the frame. In Hillsborough’s mild but damp winters, a broken seal on a west-facing window can turn into moisture inside the wall cavity by February.
What Seal Failure Looks Like on an Older Estate
Many Hillsborough homes built in the 1940s through the 1960s still have original single-pane steel windows. When moisture gets between the glass and the steel profile, it corrodes the frame from the inside. You may not see the damage until we remove the sash. Our crew documents the condition before any work starts, so you are never surprised by the bill.
Repair Versus Replacement
On a mid-century steel casement, replacing just the glass while keeping the original frame is often the right call. It preserves the architectural lines and avoids a full frame rebuild that the town’s design review would need to approve. But if the jamb behind the steel is rotted, a seal repair alone will fail within a year. We will tell you which situation you have, and put the price for both options in writing before you choose.
Energy Efficient Windows in Hillsborough
Energy efficient windows in Hillsborough typically run $1,100 – $4,200 per opening installed, with large south-facing window walls on the upper end of that range. Low-E glass, which is a thin coating that reflects heat while letting light through, is now standard on nearly every replacement we install. For Hillsborough’s sunny southern exposures and the UV fading they cause, solar control glazing makes a measurable difference in both comfort and long-term interior preservation.
Low-E Glass and Solar Control
Hillsborough homes with floor-to-ceiling glass on the south side pick up serious afternoon heat from May through October. The right low-E coating cuts that heat gain by roughly 30 – 45 percent compared to clear single-pane glass. It also blocks most UV radiation, which is what fades drapery, furniture, and hardwood floors. We spec the coating based on the elevation, not a generic default.
Why Hillsborough’s Design Review Matters Here
The town’s design review standards require that any visible change to street-facing elevations preserve the original architectural character. Some homeowners assume that means they are stuck with single-pane glass, but that is not the case. Modern laminated low-E units can match the sightlines and profile of the original steel frames while delivering performance the old glass could not touch. We have handled that exact conversation with Hillsborough’s review board on multiple projects.
Trusted Brands We Service in Hillsborough
We are authorized to install and replace products from eight manufacturer lines: PGT, CGI, CWS, ES Windows, ECO Window Systems, Mr-Glass, Therma-Tru, and ViewLux. For Hillsborough homes, the three we most often spec are PGT for impact-rated and coastal-grade glass, Therma-Tru for period-appropriate entry doors, and ViewLux for large fixed picture windows and window walls. We hold inventory relationships with each manufacturer’s regional distribution, which means shorter lead times for Hillsborough customers and fewer surprises when a custom-sized unit has a production delay. If you already have a preferred brand, we will work within it. If you want a recommendation based on your elevation and exposure, call (831) 273-7126 and we’ll walk you through it.
Common Window Replacement Problems We See in Hillsborough Homes
- Water intrusion behind original steel frames. Hidden rot in the jamb and sill only surfaces during winter rains, and by the time you see a stain on the interior wall, the framing is usually already compromised. We open the wall, document the condition, and price the repair before ordering glass.
- Undersized or termite-damaged framing around oversized window walls. Homes built before modern span tables were not designed for the glass sizes they carry. When we demo an old window wall, we frequently find headers that are undersized for today’s code. That upgrade gets written into the allowance at contract, not added as a surprise change order.
- Single-pane glass that cannot meet solar control standards. South-facing elevations in Hillsborough take full afternoon sun, and original single-pane glazing offers almost no UV or heat protection. The fix is usually re-glazing the existing frame with low-E insulated units rather than a full frame replacement.
- Failed waterproofing behind the sill flashing. Even on well-maintained estates, the original waterproofing layers from a 1950s or 1960s build have a finite life. Once they fail, water tracks into the structure. The good news: we can repair the waterproofing during replacement without ripping out more wall than necessary.
One job on a 1950s estate off Crystal Springs Road captures this well. Our crew opened the wall around a leaking steel casement and found rotted jamb framing and outdated wiring in the chase. We documented the condition, wrote the allowance into the contract before starting, and after the homeowner approved the revised scope, we re-glazed the original steel sash with Low-E insulated glass units, bringing the opening up to current code while keeping the mid-century lines intact.
Pricing for Window Replacement in Hillsborough, CA
Here is the straight answer. Insert window replacement, where the new window fits into the existing frame, runs $850 – $3,400 per opening in Hillsborough. Full frame replacement, where we remove the entire window down to the rough opening and rebuild the waterproofing, runs $1,900 – $6,800 per opening. The higher end reflects oversized units, steel frame restoration, and structural repairs to the surrounding framing. Permit fees and any required design review filing are separate line items, always written into your estimate before work starts. Call (831) 273-7126 for a free walkthrough and written quote. You will know the full number before you commit to anything.
What moves the price: the size of the opening, whether we are preserving the original frame, the glass package (low-E, impact-rated, laminated), and what we find when the wall is opened. We handle those unknowns with a written allowance in the contract. If the framing is worse than expected, you approve the revised number in writing before we touch it. That is the only way we work.

FAQs About Window Replacement in Hillsborough
Any change to a street-facing elevation in Hillsborough typically requires design review, and structural work requires a permit. We handle that process for you. Our team pulls the permits, files the design review documents with the town, and includes the fees as a written line item in your estimate before any work begins. You will know the full process and cost on day one.
Call (831) 273-7126 to schedule a walkthrough and we will confirm what your specific home will require.
Yes, in most cases we can re-glaze the original steel sash with laminated low-E insulated glass units that meet current code while keeping the original frame profile. This preserves the mid-century lines and avoids a full frame rebuild. We have completed this exact work on multiple Hillsborough estates, including homes along Crystal Springs Road and Skyfarm Drive.

We document it, write the repair into an allowance that was already in your contract, and get your written approval before we do the work. If the framing is worse than expected, the revised scope and price go on paper first. No one starts cutting until you sign off. That is the Garrison Standard on every Hillsborough job.
Call (831) 273-7126 to schedule a walkthrough and we will assess the visible condition of your framing before we quote the job.
Yes. Impact-rated laminated glass with a low-E coating is available from PGT and other manufacturers we work with, and it can be specified to meet both solar control requirements and current design pressure ratings for Hillsborough exposures. This is a common spec for the oversized window walls on south-facing elevations.
Call (831) 273-7126 for a free estimate on impact-rated low-E replacement glass for your window wall.
Not automatically, but it is a real possibility if the original wiring runs through the wall chase directly behind the window, as we found on a Crystal Springs Road estate. When we open the wall, we inspect and document what is there. If a wiring upgrade is required by code, it becomes an approved written change before any electrical work begins. The window replacement itself does not trigger the upgrade; opening the wall may expose existing conditions that require it.
