Trusted Door Installation for San Francisco Homeowners

A door that sticks, drafts, or sits crooked in its frame is more than a nuisance. It lets fog-damp air into your entryway, lets heat slip out during the winter months, and turns every coming and going into a small frustration. We started with the idea that replacing a door should feel like opening a light well into your home: clear, measured, and brighter at the end than it was at the beginning. Our installers show up in uniform, with background checks already on file, and they lay down drop cloths and wear shoe covers before the first tool comes off the truck. We have been part of the Cedarwell network since 2010, and every door we hang in San Francisco is covered by the 365-Day Done Right Promise. If the finished work is not right, we make it right.

Front Door Replacement

Front Door Replacement means removing your existing entry door and installing a new slab and, in many cases, a new frame that seals tightly against the hill winds and salt air that move through San Francisco neighborhoods like the Sunset, the Richmond, and Noe Valley. For homeowners looking for professional Door Installation - San Francisco, this service addresses the specific challenges of coastal weather. We replace front doors when the old one has warped, the locking hardware no longer sits flush, or the seal has failed enough that you can see daylight around the edges. A steel or fiberglass front door replacement from Lightwell Windows San Francisco usually runs between $1,200 and $2,800, with wood veneer and custom glass inserts at the higher end. We specify Therma-Tru doors often for San Francisco homes because their composite frames handle the damp without swelling the way solid wood can.

What Gets Replaced

The old slab comes out first, then we check the rough opening for rot or settling before the new frame goes in. Kiln-dried shims, exterior-rated fasteners, and a continuous bead of sealant go in before the door is hung. If your threshold is worn from a decade of damp shoes and stroller wheels, that gets addressed in the same visit.

What It Costs

Entry door replacement with a standard Therma-Tru slab and no frame repair starts around $1,200. Add sidelights, glass, or a custom finish and the number moves toward $2,800. We hand you a written price that shows the door, the labor, and the fasteners and sealant, so there is no line item that surprises you later.

Door Replacement

Door Replacement is the broader service of swapping out any failing interior or exterior door rather than patching it, and it tends to become necessary when a door no longer swings, latches, or seals the way the house needs it to. We see this a lot in older San Francisco homes where the original doors were hung before the foundation shifted and the frames settled. Homeowners in nearby communities can also access our Daly City Door Installation services for similar foundation-related door issues. Replacing a door instead of repairing it makes sense when the slab itself is cracked, the core has gone soft from moisture, or the hinges have pulled loose more than once. A straightforward door replacement with a standard slab runs $850 to $1,800 through Lightwell Windows San Francisco, with the higher number covering exterior-grade materials and frame work.

Interior vs. Exterior

Interior door replacement is mostly about fit, swing, and how quietly the latch catches. Exterior work adds weather sealing, thermal performance, and security hardware into the same job. We treat them differently because the stakes are different: an interior door that drags is an annoyance, while an exterior door that seals poorly is a standing invitation to damp and heat loss.

When Replacement Beats Repair

If a door has already been planed down once, filled with wood putter, or shimmed at the hinges, replacement is usually cheaper than doing all of that a second time. A split panel or a rotted bottom rail will keep failing no matter how well it is patched. We tell you when a repair will hold and when it will not.

Sliding Glass Door Replacement

Sliding Glass Door Replacement swaps an older, dragging, or fogged sliding patio door for a new unit that rolls easily and seals against the fog that rolls through the Avenues and the hills. San Francisco homes with decks, rear yards, or garden access often have a slider that has not opened smoothly in years; the track is packed with debris and the rollers are worn flat. A slider replacement through Lightwell Windows San Francisco generally costs between $1,800 and $3,200, depending on glass package and whether the new frame is vinyl, aluminum, or fiberglass. We stock and install glass packages from ECO Window Systems and ViewLux, both built to shed water and resist the kind of thermal cycling that causes older sliders to fail.

Track and Roller Work

The new unit gets a fresh track, new rollers, and a clean, square opening rather than being forced into a frame that has shifted over the years. We square the rough opening with shims, level the track, and set the rollers so the door glides with one hand. That glint of daylight through clean glass after the job is done is exactly the feeling we aim for.

Safety Glass and Code

Any slider we hang in a San Francisco home meets tempered glass requirements for doors, and we pull permits and schedule the required inspection when the project calls for it. The team works with pet-safe sealants when there is an option, which matters in homes where a dog noses at the new threshold within minutes of the crew leaving.

Storm Door Installation

Storm Door Installation adds a second door outside your primary entry to block wind, rain, and salt air while still letting natural light into the entry. In San Francisco, storm doors are less about snow and more about the months of sideways drizzle that soak front entries in the Outer Sunset and the Richmond. A storm door from Lightwell Windows San Francisco installed on your existing entry typically costs $650 to $1,400 depending on glass options, frame material, and whether we need to build out the opening to accept the new door. It is a lower-cost way to protect a main door and add a buffer of air between the street and your living space.

Ventilation and Light

Most storm doors we install have interchangeable or retractable glass panels, so in summer the upper glass drops away and lets the afternoon breeze move through while the screen keeps kids and pets on the right side of the threshold. In winter, the glass stays in place and the extra layer holds more heat in the entry. The fit is the important part: a storm door that is hung even slightly out of square will rattle in the wind.

Protecting the Entry Door

A storm door takes the brunt of the wind-driven rain that would otherwise soak your main door season after season. That protection extends the life of a front door that might have cost twice as much. We hang them with the same drop cloths and shoe covers as any other job, and we explain the price before the first screw goes in.

Sliding Glass Door Installation

Sliding Glass Door Installation is the process of installing a new sliding door where none existed, or replacing an existing wall or window opening with a slider to open up light and access to a yard or deck. We do this work in San Francisco when a homeowner wants to connect an interior room to a rear patio, a garden, or a view corridor that has been closed off for years. Our Door Installation - South San Francisco team handles the same opening-up projects for homes just south of the city limits. A new slider installation runs $2,200 to $3,500 through Lightwell Windows San Francisco, with the cost driven by the size of the opening, any structural header work, and the glass package selected. ECO Window Systems and ViewLux sliders are regular choices on these jobs because they carry clean sightlines and strong sealing hardware.

Opening Work

Most slider installations begin with some opening work: cutting back drywall, checking for load-bearing conditions, and installing a proper header if the new opening is wider than the existing framing. This is not a job where you skip the permitting step. We pull permits, schedule the inspection, and show you the passing report when it comes.

Light and Access

The reason San Francisco homeowners add a slider is almost always the same: they want daylight to move deeper into the house and they want to step outside without fighting a swinging door. That is the light well idea, applied to your own floor plan. The new glass brings the backyard into the room even when the door is closed.

Door Repair

Door Repair corrects specific failures: a striker plate that no longer aligns, a hinge pulling away from the frame, a door that rubs the floor or sticks at the top corner, a failed weather seal that lets damp air into the entry. San Francisco houses settle, and a door that fit perfectly when it was hung in 1962 rarely fits the same way now. Repair work through Lightwell Windows San Francisco typically runs $150 to $600 depending on what has failed, and we give you that number before the work starts. If the repair cannot be counted on to last, we tell you honestly and quote a replacement instead.

Hinge and Alignment

Door sag is almost always a hinge or frame problem rather than a slab problem. We re-seat hinge screws into solid wood with longer fasteners, adjust strike plates so the latch catches without slamming, and plane edges only when the door has genuinely swelled with moisture. A door that closes with a soft click instead of a shove changes how a hallway feels.

Weather Sealing

In San Francisco’s damp, a failed threshold or worn sweep lets more than air into the house; it lets moisture wick into the bottom rail and start rot that spreads before you see it. We replace sweeps, thresholds, and jamb seals with products rated for exterior exposure. It is a small repair that often delays the need for a full door replacement by several years.

Exterior Door Installation

Exterior Door Installation covers any door on the perimeter of the home that faces weather: front entries, back doors, side doors leading to a garage or basement, and doorways from a kitchen to a deck. We do this work in San Francisco using door slabs from manufacturers like Therma-Tru and Mr-Glass, chosen for the way they hold up against constant damp and the salt air that comes off the Pacific. For properties across the bay, our Emeryville Door Installation service uses the same weather-resistant materials and techniques. A new exterior door installed through Lightwell Windows San Francisco runs $1,200 to $2,800 on average, including the door, hardware, sealant, threshold, and any minor frame correction needed to make the fit square.

Frame and Threshold

The frame is where an exterior door succeeds or fails. We inspect the rough opening for rot at the corners and bottom, treat or replace any compromised wood, and set the new frame in with shims behind every hinge and latch point. A solid threshold and a continuous seal around the jamb are what keep the rain on the outside and the heat on the inside.

Hardware and Security

We install the lock hardware as part of the door package, with the strike plate anchored into the frame rather than just into the jamb trim. That detail matters for security and for how the door feels when it closes. A properly set strike plate means the deadbolt slides home without friction, and the door does not flex under a push.

French Door Installation

French Door Installation sets a pair of hinged doors, usually with glass panels, into an interior or exterior opening, and it is one of the most requested door upgrades in Victorian and Edwardian homes across San Francisco. An exterior French door installation typically costs $2,000 to $3,500 through Lightwell Windows San Francisco; interior French doors run lower, from $1,200 to $2,200, depending on glass spec and hardware. ViewLux and Therma-Tru doors get specified often on these jobs because their glass packages and panel construction hold square in the city’s shifting frames.

Level and Square

Pair doors only look right when both slabs hang plumb and meet evenly at the astragal. That requires a level floor, a square opening, and hinge mortises cut to the exact depth of the hinge leaf. We shim, adjust, and test the swing on both panels before the hardware goes on, so the doors close in one motion instead of two.

Light and Room Boundary

Interior French doors keep a room feel open while giving you the option of closing it off: a home office that shares light with the hallway, a den that does not need to be sealed tight all day. The glass lets the light well effect do its work. Exterior French doors do the same for a rear wall, opening the whole back of the house to the garden after years of a single narrow door.

Brands We Service

We carry Therma-Tru exterior doors because in San Francisco’s damp, a composite or fiberglass slab that does not swell beats wood every time. The frames and thresholds sit square, the finish holds in the fog, and the factory hardware spec matches what our installers expect to see on a job.

We install ViewLux and ECO Window Systems sliding and hinged glass doors because their sealing systems and roller hardware are built for repeated cycling without binding. Mr-Glass rounds out the selection for entry door and glass panel work where a clean, modern line matters. Whichever brand you have, our installers understand how the door is built and how it should come apart for service, so the replacement follows the original engineering rather than fighting it. Whether you have a Therma-Tru, a ViewLux, or any other make hanging in your San Francisco entry, we can help you plan the swap.

Signs You Need a Pro Right Now

• Daylight visible around the closed door. If you can see light through the gap between the slab and the jamb, the weather seal has failed and damp air is moving through your entry all day. That same gap lets heated air out and pulls exterior moisture into the frame wood.
• The door needs a shoulder to close. A door that sticks and needs force is telling you the frame or the hinges have shifted. Forcing it closed loosens the hinge screws further and bends the strike plate until the latch stops catching altogether.
• Rust streaks below the hinges or threshold. Rust means water is sitting somewhere it should not, usually because a threshold is worn through or a corner seal has opened. The rust you see is the metal telling you the surrounding wood is wet.
• The deadbolt does not throw without lifting the handle. When the latch and the strike plate are out of alignment, you lose security in a way that worsens with every closing. A door that does not lock true is a door that is already failing.
• You can hear the street through the door. San Francisco traffic and sidewalk conversations should not sound like they are in your living room. Excessive noise pass-through usually means the slab has lost density or the seals have gone, and both are conditions a pro can fix with the right replacement.

Our Process, Step by Step

1. 1
   Measure and assess. We measure the slab and the rough opening in three places each, because San Francisco frames are rarely as square as they look from the hallway. Keith Yamada or one of our installers checks the existing frame for rot, the floor for level, and the hinge points for wear before any price is written.
2. 2
   Written estimate. You get a line-item price showing the door, the hardware, the sealant, the fasteners, and the labor, with no open-ended allowances. The estimate includes a permit fee line when the project requires one, so there is no invoice surprise after the work passes inspection.
3. 3
   Prep and protect. On install day, the crew lays drop cloths down the path from the entry to the work area, puts shoe covers on at the door, and moves only what needs moving after asking first. The C.A.R.E. values are in play on every visit: Clean up like it is our own home, Ask before we move anything, Respect quiet hours, Explain the price before the work.
4. 4
   Install and seal. The new door goes in with shims behind every hinge, a continuous bead of sealant around the jamb, and a threshold set level against the floor. We test the swing, the latch, and the deadbolt before we call the job done. If glass or pets are involved, we use pet-safe sealant wherever a suitable option exists.
5. 5
   Show you the result. Before the crew leaves, we photograph the cleaned work area and walk you through what was changed. The 365-Day Done Right Promise stays with the job: if something is not right, Lightwell makes it right.
