Door installation in San Leandro costs $450 to $2,800 for most exterior entry doors, $600 to $3,200 for sliding glass doors, and $350 to $1,800 for storm doors, depending on size, material, and whether your rough opening needs structural work. Most standard installations are finished in one day, though doors in older San Leandro homes with non-standard rough openings may take two. Our crews are local to the Bay Area and routinely work in San Leandro neighborhoods like Estudillo Estates, Broadmoor, Washington Manor, and Marina Faire, so we can usually get to your home within a day or two of your call.
If you want a written price before any work begins, call (831) 480-4124. Keith Yamada leads our San Leandro door installation team, and a live person answers that number 24/7, not a recording.
Why Lightwell Windows San Francisco Is San Leandro’s Preferred Door Installation Company
San Leandro homeowners call us because we do not treat a door replacement as a generic swap. We know the difference between a 1940s bungalow in Washington Manor and a 1960s ranch in Bay-O-Vista, and we know what each one requires. A door that fits a newer tract home in Castro Valley will not simply drop into a San Leandro opening that was framed 70 years ago for a different standard. That matters, and it shows up in the final result.
Every job gets a written price before any work starts. That is not a promotion. It is how we operate. You will know the exact number for materials, labor, permits, and disposal before we touch your door frame. Keith Yamada has built our San Leandro reputation on that rule, and on the Door Installation team’s habit of showing up when we say we will. Our technicians are background-checked, uniformed, and trained to follow the C.A.R.E. values on every visit: Clean up like it is our own home, Ask before we move or touch anything, Respect your family’s time and quiet hours, and Explain the price before the work.
We carry shoe covers and drop cloths on every job, and we take a photo of the clean-up before we leave. If you have kids napping or a dog that gets anxious around strangers, tell us. We will work around it. That is not extra service. That is the standard.
Styles & brands we work with










Storm Door Installation in San Leandro
Storm Door Installation in San Leandro protects your primary entry door from the bay winds and salt air that roll in off the shoreline, while letting you keep the main door open for light and airflow on those cool, foggy summer afternoons. A storm door costs $350 to $1,800 installed in San Leandro, depending on the material, glass package, and whether the existing door opening needs any adjustment before the new frame goes in.
Homes within a mile of the shoreline, in neighborhoods like Marina Faire and along Neptune Drive, see more salt corrosion on metal door hardware than homes further inland. A storm door acts as the first line of defense, taking the brunt of the wind and salt so your primary entry door’s hinges, threshold, and weatherstripping last longer.
What the Job Involves
We remove the old storm door if one exists, check the surrounding trim and sill for rot or corrosion, and set the new door in a properly shimmed and sealed opening. On San Leandro homes with original wood trim, we match the new door’s color and hardware finish to the existing entry so the addition looks intentional rather than bolted on.
When a San Leandro Homeowner Needs One
You need a storm door if your front entry faces the prevailing west wind and you are tired of air leaks, or if you want to leave the main door open during temperate months without letting insects and dust inside. You also need one if your primary door is aging and you want to extend its life by a few more years before a full replacement makes sense.
Sliding Glass Door Installation in San Leandro
Sliding Glass Door Installation in San Leandro opens up the back of a mid-century ranch or bungalow to the backyard, and costs $600 to $3,200 installed depending on the door width, glass package, and whether your existing rough opening needs structural reinforcement. Many San Leandro homes built in the 1950s and 60s have original aluminum sliders with single-pane glass that leak air, stick on their tracks, and do not meet current Title 24 energy standards.
Replacing one is not always a straight swap. The rough openings in many San Leandro ranch homes were framed to non-standard dimensions, so a big-box prehung slider will often leave oversized shim gaps that leak air and fail inspection. We measure and fit to your actual opening, not the nearest off-the-shelf size.
Ranch Home Considerations
If you own a ranch-style home in Washington Manor or Bay-O-Vista, you may want to replace a slider with a hinged French door for easier access to the patio. That is doable, but it requires reframing the opening and verifying the lintel above the door can handle the span. We handle that structural work in-house, and we pull the permit before we start.
Glass and Airflow
San Leandro’s foggy summers mean you rarely need the highest solar-heat-gain glass. A low-E double-pane package works well here. If your door faces south or west and gets afternoon glare off the bay, we can upgrade to a glass package with a stronger solar control coating to keep the kitchen from turning into a greenhouse.
Trusted Brands We Service in San Leandro
We install and service doors from Therma-Tru, ViewLux, PGT, and other manufacturers we trust, and we keep common replacement parts on hand so San Leandro customers are not waiting a week for a hinge or a lock set. Therma-Tru fiberglass doors work especially well in San Leandro because they do not warp or rust in the salty bay air the way cheaper steel doors do. PGT makes a strong line of impact-rated doors for homes near the shoreline that want the extra wind protection. ViewLux sliding doors come in a range of sizes and glass options that fit the non-standard openings we see in mid-century San Leandro homes. We recommend the door that fits your house, your style, and your budget, not the brand we happen to have in the warehouse.

AfterCommon Door Installation Problems We See in San Leandro Homes
- Non-standard rough openings in 1940s-60s ranch and bungalow homes. Original door frames were often built to sizes that do not match today’s prehung doors. Forcing a standard door into a non-standard opening creates large shim gaps, air leaks, and a door that binds or sags within a year.
- Rusted steel doors and jambs near the shoreline. Salt air from the bay accelerates corrosion on steel door skins and hardware, especially within a mile of the water. We see rusted thresholds, frozen lock cylinders, and weatherstripping that has crumbled away, letting wind and damp air into the house.
- Original steel casement-adjacent side doors in Estudillo Estates and Broadmoor. These 1930s doors are prone to rusting at the base and are difficult to replace because their dimensions and trim profiles are unusual. They require a custom-fit door and careful work to preserve the home’s architectural character.
- Skipped permits and wind-load verification. We have been called out to fix installations where the previous contractor did not pull a permit or verify that the new door met San Leandro’s wind-load requirements for coastal exposure. The homeowner found out only when an insurance adjuster flagged the installation during a claim.

FAQs About Door Installation in San Leandro
Yes, in most cases San Leandro requires a building permit for exterior door replacement, especially if the rough opening is being altered, the door is in a location that requires egress, or the work involves structural reinforcement. We pull the permit as part of the job, and the permit fee appears as a line item on your written quote. A quote that does not mention a permit is a red flag. Call (831) 480-4124 to ask about your specific door, and we will tell you straight what is required.
Doors within about a mile of the San Leandro shoreline generally need to meet higher wind-load ratings than doors further inland, because the exposure to bay gusts is greater. The exact rating depends on your home’s location, the door’s height above grade, and whether the door is on the windward side of the house. We verify the required rating for your specific address before ordering a door, and we document compliance on the permit. Call us at (831) 480-4124 if you are not sure what your existing door was installed with.
Insurance carriers will sometimes apply a premium credit or reward documented, code-compliant door and window upgrades, particularly wind-mitigation features on coastal exposure homes. What matters for a claim is whether the installation is documented: permit pulled, inspection passed, wind-load verification on file. A door installed without that documentation can be flagged as non-compliant during a claim, which is the last place you want to discover a problem. We give you the paperwork. Call (831) 480-4124 and ask us what documentation we provide with every installation.
Yes, you can, and we do that conversion regularly in San Leandro ranch homes. It requires reframing the rough opening, adding a properly sized header or lintel if the span increases, and matching the new door’s style to the home’s original architecture. Because San Leandro’s design guidelines require replacements to fit the home’s character, we take care to match trim profiles and proportioning. Call (831) 480-4124 to schedule a site visit, and we will measure your opening and give you a written price for the conversion.
A compliant quote includes the permit fee, the wind-load verification for your specific address, structural reinforcement of the jamb and framing where required, matching trim work per the city’s design guidelines, and the manufacturer’s documentation. A cheap quote leaves out the permit, skips the wind-load check, shims the door into a gap it was not built for, and leaves you to deal with the consequences later. Get both quotes side by side and subtract the missing pieces. The cheap one stops looking cheap. Call (831) 480-4124 for a written quote that includes everything, on purpose.
