Fast, Reliable Door Installation Across San Leandro
Door installation in San Leandro runs $950-$4,200 for most single-entry replacements, with the price set by frame condition, door material, and whether the rough opening needs reframing. Homes in the flatlands west of I-880 rarely accept a stock pre-hung door without modification; the 1945-1968-era frames measure to pre-modern sizing, so we survey, shim, and document before quoting. Sightline Windows & Doors has installed thousands of openings across the East Bay under the Haven Standard since 2012, and every San Leandro job starts with a measured survey you keep. That survey and the written quote are the same document. Call (509) 265-6387 to schedule a free estimate.
Why Sightline Windows & Doors Is San Leandro’s Preferred Door Installation Company
San Leandro homeowners read the three-star reviews before they call anyone, and we respect that instinct. The evidence we hand over speaks before we do: a written price before work starts, a documented photo record when the job finishes, and the 365-Day Done Right Promise on every opening. If it’s not done right, we make it right. That’s Haven Clause 1 and Haven Clause 4, not a courtesy.
Our technicians arrive in uniform, background-checked, with license numbers on the record before they walk up the driveway. No subcontractor roulette. The person confirmed on the schedule is the person at your door in Davis Tract, Estudillo Estates, or Bay-O-Vista. We also answer the phone with a live person, 24/7. No callback window.
Local knowledge matters here because San Leandro’s housing stock is not generic. When a Washington Manor homeowner calls about a sticking entry door, we don’t guess; we check the threshold, the hinge sag, and the frame moisture reading. Salt-laden marine air from the Bay compresses weatherstripping faster here than in Castro Valley, and we quote accordingly.
Our Door Installation Services in San Leandro

Entry Doors
Entry door replacement in San Leandro typically runs $1,100-$4,200 installed. Post-war stucco homes in the flatlands often have a 4/9 rough opening from the original 1950s frame, so a stock 36-inch pre-hung unit won’t always seat without careful shimming or a near-custom order. We measure the rough opening, record the sightline, and write the scope before any tool is lifted. Fiberglass and steel entry doors from Therma-Tru and CGI hold up well against the morning marine layer that lingers up to Estudillo Road.

Hurricane-Proof Front & Entry Doors
Impact-rated front doors in San Leandro run $2,800-$6,500 installed, depending on glazing area and frame retrofitting. Homes west of I-880 get the full force of the Bay wind corridor through the East Bay hills’ coastal gap, and while San Leandro isn’t in a hurricane zone, the same impact-rated CGI and PGT assemblies specified for Florida also stop windborne debris and offer a real security upgrade on Washington Avenue and Manor Boulevard. We explain the U-factor and SHGC plainly: thermal resistance and solar heat gain, in dollars and performance terms, not marketing shorthand.

French & Double Doors
French and double door installation in San Leandro runs $1,800-$5,500, with the spread driven by whether you’re replacing a single slab or reframing a wider opening. The 1950s-60s tract homes in Floresta Gardens and Davis Tract often have narrow original openings not built for double-door swings, so we document the header and lintel condition before quoting. This is also where the salt-air issue shows up fastest: exposed hinges and threshold hardware on west-facing double doors pit and seize if not specified in marine-grade finish.

Replacement Doors
A standard replacement door in San Leandro runs $950-$2,600 for a same-opening swap with a stock or near-custom unit. The phrase “same-opening” does the heavy lifting there: if the original frame is square and the sill isn’t rotted, the job is straightforward. If the marine layer has been sitting on that sill since the Truman administration, the frame gets pulled and we do it right. We don’t hide that in the quote. Haven Clause 5: no surprises.

AfterTrusted Brands We Service in San Leandro
Sightline specifies from eight manufacturer lines, and for San Leandro we lean on CGI, CWS, and ES Windows for impact-rated and energy-efficient units that hold up to the salt air. We stock common threshold, weatherstripping, and hinge parts for these lines locally, which means a replacement door adjustment on a Bay-O-Vista home doesn’t wait on a freight truck from the Midwest. The brand on the label matters less than the performance spec on the survey. We’ll tell you which tier fits your opening, your budget, and your exposure to the morning fog.
Common Door Installation Problems We See in San Leandro Homes

- Compressed weatherstripping from marine-layer moisture: The daily fog cycle on the flatlands west of I-880 saturates door seals, then dries them in the afternoon sun. This compression-rot cycle fails weatherstripping twice as fast as inland Alameda County, which is why we quote replacement thresholds and seals as part of any door job here.
- Rotted wood sills behind stucco surrounds: Water intrusion at the sill-to-stucco junction is a repeat offender on 1945-1968 tract homes. We see it most on north-facing doors in Estudillo Estates, where the marine layer sits longest. A door swap alone doesn’t fix it; the sill has to come out and the flashing has to be redone.
- Out-of-square 4/9 rough openings: The original door frames in post-war San Leandro homes were built to a standard that doesn’t match today’s pre-hung door dimensions. We shim, we reframe, and we document the final reveal with photos so you can see the gap is even, not just trust that it is.
- Salt-pitted hinges and hardware on west-facing doors: The Bay wind corridor carries fine salt spray into the flatlands. Exterior hinges on doors that face west toward the water corrode and bind faster than any other orientation. We specify marine-grade stainless hardware on those openings as standard practice, not an upsell.
Pricing for Door Installation in San Leandro, CA
Line-item pricing matters in San Leandro; homeowners here want the number on the page before they pick up the phone, and Haven Clause 1 says the written price comes before any work starts. Here’s what we quote on the flatlands:

FAQs - Door Installation in San Leandro

Most San Leandro homes get a measured survey scheduled within a few business days, with installation typically 1-3 weeks after the survey, depending on whether the door is stock, near-custom, or impact-rated.

Yes, we cover the full city, including Washington Manor, Estudillo Estates, Bay-O-Vista, Davis Tract, Floresta Gardens, and the Marina area. Each neighborhood has its own frame-age and salt-air quirks, and we quote those details specifically, not from a generic East Bay price sheet.
Stock pre-hung door replacements can often be scheduled within one week if the opening is standard and the frame is sound. Impact-rated and custom doors take 2-3 weeks from order to installation because they’re manufactured to spec, not pulled from a warehouse shelf. Call (509) 265-6387 and we’ll give you a straight timeline in writing.
Pricing in San Leandro is generally comparable to Oakland and Alameda for the same scope, with entry door replacement running $950-$4,200 across the East Bay. San Leandro’s 1945-1968 housing stock means more jobs need sill repair or frame shimming than in newer cities, which adds line items. Our quote shows exactly which ones apply.
