What makes Hillsborough different from every other Bay Area town isn’t the architecture; it’s what surrounds the house. Deep eave overhangs, mature oaks on nearly every lot, no streetlights, no sidewalks. A patio door here sits in shade most of the year, which means flashing details and drainage matter more than the glass spec. We account for that on every job.
Why Meridian Windows & Doors Is Hillsborough’s Preferred Patio Door Installation Company
We show up when we say we will. That sentence alone separates us from most of what Hillsborough homeowners have dealt with before. Elliot Vance leads our team, and the standard he set is simple: the price goes on paper before a single screw turns, the crew is background-checked and uniformed, and the work is covered in writing for 365 days. If something fails within that year, we come back at no charge.
Hillsborough homeowners call us because we know what a 1960s raised ranch off Floribunda Avenue needs versus a 1990s custom build near Burlingame Country Club. The rough openings are never square. The original aluminum frames from the mid-century are usually corroded at the jamb. The deck ledgers have decades of weather behind them. None of that surprises us, and none of it gets handled as an afterthought.
We also answer the phone. A live person picks up 24 hours a day, every day of the year. No voicemail loops, no “we’ll get back to you next business day.” When you call (817) 686-2228 about a patio door in Hillsborough, you talk to someone who can actually help.
Sliding Door Installation in Hillsborough
Sliding door installation in Hillsborough starts with the rough opening, not the door itself. Most homes here were built between the 1950s and 1980s, and the openings were framed with the tolerance of the era, which means they are rarely square and plumb. We shim, correct, and flash the opening before the new unit goes in. That is the difference between a door that glides for 20 years and one that binds by the second season.
Most sliding door installations in Hillsborough run $2,800 – $6,400 for a standard two-panel unit, installed. That includes tear-out of the old door, rough-opening correction, new head flashing, a sloped sill pan, and interior and exterior finish work. The final number depends on the size of the opening, the door line you choose, and whether we find rot in the jamb once the old frame comes out.
Choosing the Right Sliding Door for a Hillsborough Exposure
West-facing sliding doors on Hillsborough’s wooded lots are a particular problem. The afternoon sun comes through clear glass and turns the room into an oven, even with the oaks. We spec low-E insulated glass on nearly every west-facing door here, a thin coating that reflects heat while letting light through. It costs a few hundred dollars more, and it changes the comfort of the room in a way you notice the first week it is installed.
What the Installation Day Looks Like
We arrive with the new door, the flashing materials, and a plan for the old door’s disposal. Tear-out takes an hour or two. Rough-opening correction takes another hour. Setting the new door level and square, flashing the head, installing the sill pan, and sealing the threshold takes most of the day. By the end of the day, the door operates, the site is clean, and we walk you through the warranty in writing.
Patio Door Repair in Hillsborough
Patio door repair in Hillsborough covers everything from a slider that drags on the track to a French door that will not latch, and the cost runs $180 – $600 for most repairs. The most common call we get from Hillsborough homeowners is a door that is suddenly hard to open or close, and most of the time the cause is either a dirty or bent track, worn rollers, or a door that has settled out of square over the years.
Before we quote a repair, we look at how the door sits in the opening. If the jamb has swollen from a rotted deck ledger, new rollers will not fix the problem; the water entry has to be addressed first. We tell you that straight, because a $300 roller replacement on a door with a leaking threshold is a waste of your money.

Roller and Track Repair
Sliding door rollers wear out, especially on the heavy glass doors common in Hillsborough’s mid-century homes. We replace the rollers, clean and realign the track, and adjust the door so it glides. Most roller and track jobs run $180 – $320.
Threshold and Seal Replacement
A patio door threshold that has cracked or pulled away from the deck ledger lets winter rain inside. On Hillsborough’s raised deck conditions, this is the most common repair we do. We remove the old threshold, inspect the framing beneath for rot, replace what needs replacing, and set the new threshold so it slopes away from the house. These repairs run $300 – $600, more if the framing beneath has rotted.
Trusted Brands We Service in Hillsborough
We are authorized to install and replace patio doors from PGT, CGI, CWS, ES Windows, ECO Window Systems, Mr-Glass, Therma-Tru, and ViewLux. That matters in Hillsborough because the right door for a shaded, wooded lot off Ralston Avenue is not necessarily the same door you would put on a sunny Palo Alto townhouse. PGT’s laminated glass is a strong pick for west-facing sliders here. CWS and ES Windows offer the cleaner sightlines a lot of Hillsborough homeowners want on mid-century ranch layouts. Because we stock local parts and have direct relationships with these manufacturers, we can usually turn a warranty or replacement part around faster than a general contractor who has to order everything through a distributor.
Common Patio Door Installation Problems We See in Hillsborough Homes
- Mismatched rough openings. Hillsborough’s mid-century ranch and split-level homes rarely have a square, plumb opening. If the new door is not shimmed and flashed properly, it will bind within months and leak by the first winter.
- Flashing failures on raised decks. Without correct head flashing and a sloped sill pan, winter rain finds the gap between the door pan and the deck ledger. We see this on wooded lots off El Cerrito Avenue and Jackling Drive more than anywhere else in the Bay Area.
- Clear glass on west-facing doors. Picking clear glass over low-E insulated glass on a Hillsborough slider means the room overheats in summer and the door sweats in winter. The glass spec is not where to save money.
- Rotted jambs from old deck ledgers. The original aluminum frames on 1960s Hillsborough homes corrode where the jamb meets a leaking deck. A new door installed over that rot fails within a year. We open the wall, fix the framing, then set the door.
Pricing for Patio Door Installation in Hillsborough, CA
A standard two-panel sliding patio door in Hillsborough runs $2,800 – $6,400 installed, depending on size and glass spec. A three-panel or multi-slide unit runs $4,200 – $9,800. A hinged French patio door falls in the $3,800 – $7,500 range. The three cost drivers are the door line you choose, the condition of the rough opening once we open it up, and whether the deck ledger or sill framing has rot that needs to be rebuilt. We give you a written line-item quote before any work starts. If we find rot once the old door is out, we stop and show you, then price the fix before we proceed. The price does not move at the door.

FAQs About Patio Door Installation in Hillsborough
Yes. Hillsborough requires a building permit when you change the size of the rough opening or alter the structural framing around a patio door. A like-for-like replacement in the same opening may not require one, but any job involving deck ledger work or header modification does. We handle permit paperwork and schedule inspections as part of the job, and we never skip the permit to save time. Call (817) 686-2228 and we will tell you exactly what your specific project needs.
On site, one to two days. Most of our Hillsborough jobs are a two-day visit: day one for tear-out, rough-opening correction, flashing, and setting the door; day two for finish work and the final walkthrough. Full timeline from deposit to final inspection is 3 – 6 weeks, driven mostly by the manufacturer’s lead time on the door itself. Call (817) 686-2228 for a firm schedule based on the door you choose.
Three things: the door line, the rough-opening condition, and whether the surrounding framing is rotted. A premium multi-slide door costs more than a standard two-panel slider. A 1960s Hillsborough opening that is an inch out of square costs more in shimming and flashing than a clean 1990s build. And if the old deck ledger has rotted the jamb, that framing repair is added work, priced in writing before we start. Call (817) 686-2228 for a free line-item estimate.
It can, if the new door upgrades the opening’s impact or security rating. Hillsborough’s wildfire-adjacent zones and wooded lots make insurers sensitive to glazing and door-spec changes. A new laminated or tempered glass unit with a proper deadbolt and multi-point lock may qualify for a premium reduction, but you will need to send your insurer the spec sheet. We provide that documentation with every install. Call (817) 686-2228 and ask about impact-rated options for your exposure.
Usually, yes. If the frame is sound and the problem is rollers, a track, a threshold, or a latch, repair makes sense and runs $180 – $600. If the jamb is rotted or the glass seal has failed, replacement is often the better use of your money. We will give you the honest answer and the numbers for both paths. Call (817) 686-2228 for an assessment.
