Fast, Reliable Door Installation Across San Carlos
Door installation in San Carlos runs between $1,400 and $4,800 for a standard entry door, with French doors landing between $3,200 and $7,500, and full-frame replacements on older ranch homes typically falling in the $2,800 to $6,000 range.

If a door is binding, leaking, or sagging out of square, call (888) 635-0804 for a free estimate.
We know San Carlos streets, San Carlos houses, and the way marine air off the bay works on a door frame over twenty years. This is not a generic install market. The older stock between El Camino Real and the water behaves differently than the hillside lots above Alameda de las Pulgas. A good door install here starts with understanding which side of the city you live on.
Why TruePane Windows & Doors Is San Carlos’s Preferred Door Installation Company
TruePane Windows & Doors was founded by Dale Kessler, a second-generation glazier who built the company on a single rule he keeps on the whiteboard: if the pane is not true, the job is not done. That principle applies to doors the same way it applies to glass. We set jambs square, we flash for wind-driven rain, and we register both manufacturer warranty layers in writing before the truck leaves your driveway in San Carlos.
We are not the cheapest bid you will get. We are the bid that shows up on time, measures twice, and writes the line-item quote on paper so you can compare what you are actually buying. Our technicians are background-checked and uniformed, trained in-house, and they work in your home the way they would work in their own mother’s house. A live person answers the phone 24 hours a day, 7 days a week. When a San Carlos homeowner calls at 7 a.m. with a door that will not latch, a person picks up.
Our Door Installation team has spent years working San Carlos homes, from the Laurel Street bungalows to the ranch houses off Brittan Avenue to the hillside lots near Crestview Drive. We know which frames corrode, which slabs shift, and which flashing details keep February rain out of your hallway. The Done Right Promise covers every job: if it is not done right, we make it right, no paperwork and no arguing.
Our Door Installation Services in San Carlos
Entry & Swing Doors
Entry doors in San Carlos take a beating from the daily marine fog cycle. Morning moisture condenses on steel and aluminum surfaces, and afternoon sun bakes it off. Over a decade, that cycle loosens threshold anchors and rots the bottom of wood jambs on bay-facing entries. We pull the old frame when it is compromised, rebuild the rough opening with sound lumber, and set the new door with stainless fasteners and a full-height flashing system. Most single entry doors in San Carlos run $1,400 to $3,200 installed, depending on whether the frame comes out or stays put.

Double & French Doors
French doors are common on San Carlos ranch homes where a back patio or garden sits off the family room. The problem we see repeatedly is the east-facing units: bay moisture gets driven into the astragal and bottom rail, and within a few wet seasons, the active door sags and the inactive door binds at the head. We pulled a racked French door on a hillside lot where February rains had shifted the clay soil under a post foundation. The slab moved so much the jamb was out of square by three-eighths of an inch and the sash bound against the threshold. We removed the frame, shimmed and rehung it with stainless fasteners, and replaced the weatherstrip with a marine-grade compression seal so the northwest wind stopped driving rainwater under the door. That is the standard, not the exception, on the western side of San Carlos. Double French door replacement typically runs $3,200 to $7,500 for a full-frame install.

Bifold & Folding Doors
Bifold doors show up most often on the higher-value hillside homes in San Carlos where indoor-outdoor living is part of the draw. The racking problem matters here more than anywhere else. A folding door system has four or more panels hanging from a top track, and when the slab moves even a quarter inch, every panel goes out of alignment at once. We check the floor for level before we ever order the unit, and we spec adjustable top-hung hardware that can be re-shimmed without tearing out tile. Bifold installations in San Carlos commonly fall between $4,500 and $9,000 depending on panel count and opening width.

Pivot Doors
Pivot doors are a hillside statement piece, often specified on newer builds and remodels in the western neighborhoods of San Carlos. They are heavy, they pivot on a top and bottom hinge point instead of side hinges, and they cannot be fudged if the rough opening is out of plum. We set pivot hardware with steel bearing plates and shim the frame dead level before the slab ever goes in. A pivot door install in San Carlos runs $3,500 to $8,500 for standard sizes, with custom units running higher based on the slab material and hardware line.

Storm Doors
Storm doors matter on the older San Carlos stock where original doors are thin and the east wind off the bay pushes rain under the threshold. A properly hung storm door cuts that moisture problem and buys years on the primary door behind it. We install storm doors on compressed timelines, often same-week once the unit is in stock, and the price in San Carlos runs $500 to $1,400 including hardware and weather stripping. For ranch homes with aluminum threshold corrosion, we replace the sill and set the storm door on a rebuilt base rather than just screwing into the old metal.

Trusted Brands We Service in San Carlos
We are an authorized installer for PGT, CGI, and ES Windows, among more than a dozen manufacturer lines. That matters in San Carlos because the bay-facing side of town needs impact-rated or marine-spec aluminum that does not corrode at the anchors, and the hillside side needs wood or fiberglass that does not rack with the clay. We quote manufacturer lines side by side on paper so you can see the price difference between a standard PGT frame and a CGI marine-grade unit, and we register both warranty layers before the truck leaves your driveway. No running out for parts that are not in stock, no second or third return visits because something was ordered wrong.
Common Door Installation Problems We See in San Carlos Homes
- Corroded aluminum door frames on bay-facing entries. The salt and moisture in the air eat through the threshold screws and jamb anchors within 15 to 20 years. The frame loosens, the door sags out of square, and hinge adjustments stop helping. Full frame replacement with stainless fasteners is the only fix that holds.
- Seasonally racked doors on hillside slabs. San Carlos clay soils expand every wet season and shrink every summer. Doors that latch cleanly in October bind by February. Hinge adjustments cannot correct a slab that has moved three-eighths of an inch. We pull the frame, re-square the rough opening, and rehang.
- Head flashing failures on west-facing hillside doors. Horizontal wind-driven rain overpowers standard weatherstrip and leaks at the top of the door. The surrounding framing rots, and by the time you see the water stain inside, the damage is already spreading. Proper head flashing and a marine-grade compression seal stop this.
- Soft rough openings on mid-century homes. The original wood framing around doors in San Carlos ranch houses has absorbed decades of coastal moisture. Screws will not bite, inserts will not seal, and any attempt to retrofit instead of replacing the frame leads to air leaks and early failure. We rebuild the opening with sound lumber before the new frame goes in.
Pricing for Door Installation in San Carlos, CA
A standard single entry door in San Carlos, installed, runs $1,400 to $3,200. French doors run $3,200 to $7,500 for a two-panel full-frame replacement. Bifold systems land between $4,500 and $9,000, and pivot doors typically run $3,500 to $8,500. What moves the number is the condition of the rough opening, the frame material you choose, and whether the existing frame can be saved or needs to be torn out and rebuilt.

FAQs - Door Installation in San Carlos
Most of the original wood rough openings in San Carlos ranch homes, especially in the 94070 ZIP between El Camino Real and the bay, are too soft and moisture-damaged to hold an insert-style replacement. The door frame is set into wood that has absorbed marine moisture for 50 to 70 years, and the screws simply will not bite. Attempting an insert leaves air gaps, leaks, and a door that binds within a season. Full-frame tearout and rebuild is the standard fix. Call (888) 635-0804 and we will inspect the opening and tell you straight whether the frame can be saved.
The daily marine fog cycle plus direct wind-driven moisture off the bay degrades standard weatherstripping on doors facing east, and the strong afternoon northwest winds push rain under west-facing thresholds. Seals on bay-facing and hillside entries fail years earlier than the same seals would inland. We spec marine-grade compression weatherstrip on exterior doors in San Carlos, not the standard bulb seal that comes in the box with most units. That upgrade costs an additional $80 to $200 depending on the door size, and it typically doubles the seal life.
First, do not force it. A door that will not latch after wet season means the slab or foundation under it has moved, and forcing it risks splitting the jamb or breaking the latch hardware. The fix is a full frame rehang: pull the frame, re-square the rough opening, shim with treated wood or composite, and reset the door with stainless fasteners. Hinge adjustments will not correct a three-eighths-inch slab shift. Call (888) 635-0804 and we will put a technician on it.
For bay-facing entries in San Carlos, composite and fiberglass frames hold up significantly better than raw aluminum or untreated wood. Aluminum corrodes at the threshold screws and jamb anchors within 15 to 20 years of marine exposure. Pressure-treated or composite frames with stainless hardware avoid that problem entirely. On the hillside side, where racking is the bigger issue, fiberglass offers dimensional stability that wood cannot match when the slab moves seasonally. Expect fiberglass frames to run 15 to 25 percent more than basic wood, and to last twice as long in this climate.
On most mid-century San Carlos homes, replacing only the slab is false economy. The frames on these houses are original to the build, which means 50 to 70 years of bay moisture has already compromised the jamb. Even if the frame looks square, the wood behind the casing is often soft, and a new slab hung on it will sag within two seasons. We will come out, pull the casing, and show you what is actually there. If the frame is sound, you pay less. If it is not, you know before the work starts. Estimates are free at (888) 635-0804.
