AfterFast, Reliable Door Installation Across San Lorenzo
Door installation in San Lorenzo usually means one thing after the first estimate: the rough opening is no longer square. We see it on nearly every 1945-to-1960 tract home we work on. The clay soil under the flatlands shifts, the post-and-pier or slab foundations move, and a door that fit perfectly in 1958 now has a jamb that racks half an inch out of plumb. Our crews have been correcting that condition on San Lorenzo ranch homes long enough to expect it before we unload the truck. If you’re in the 94580 zip code and need a new entry, French, bifold, or custom door set right the first time, call (888) 635-0804. We’ll give you a written line-item quote, not a ballpark.
Why TruePane Windows & Doors Is San Lorenzo’s Preferred Door Installation Company
TruePane was founded by second-generation glazier Dale Kessler in 2008, and the crews we send to San Lorenzo work under a rule Dale has kept on the whiteboard since day one: if the pane is not true, the job is not done. The same applies to every jamb, threshold, and hinge we set. San Lorenzo homeowners tend to stay put for twenty, thirty, forty years. They remember the contractor who left a door that binds in July and lets the marine air whistle through in January. We’d rather spend an extra forty minutes shimming an opening square than leave a callback hanging over someone’s head.
Our San Lorenzo customers call for three reasons. They have a worn postwar door that doesn’t seal, they want a higher-end replacement with real millwork, or they’ve been told by another company that their 1950s opening needs full reframing at an inflated price. Most of the time, it doesn’t. It needs a patient installer who understands clay-soil settlement and knows how to re-square an opening with precise shims before the jamb goes in. We carry that practice into every Door Installation job we contract in this area.
A live person answers our phone 24 hours a day, seven days a week. Not a voicemail tree, not a callback form. When a San Lorenzo homeowner calls at 7 a.m. with a door that won’t close after a break-in attempt or a storm, they get a real person on the line who can schedule a visit. Our technicians are background-checked and uniformed. They measure every opening twice and put quote options from different manufacturer lines side by side on paper before any money changes hands.
Our Door Installation Services in San Lorenzo
San Lorenzo’s housing stock is overwhelmingly minimal-traditional and ranch-style tract homes of roughly 1,000 to 1,400 square feet, built between 1945 and 1960. The door work those homes need breaks down into a few recurring categories. We handle all of them, but the four below account for nearly every request we field in the 94580.
Entry & Swing Doors
A stock 36-by-80 replacement door rarely drops straight into a San Lorenzo rough opening. The foundation has moved since Truman was in office, and the opening has moved with it. We re-square the opening with custom shims, set the new jamb level on all three axes, and flash it properly before the door slab ever gets hung. In the flatlands near San Lorenzo Creek, we also pay close attention to the threshold. Moisture wicking up from the creek-side humidity accelerates rot at the sill plate, and a properly flashed, sealed threshold adds years to the door assembly.
Double & French Doors
Double doors on a shifting foundation present a compound problem. If one jamb is a quarter inch out of plumb, the two leaves meet unevenly at the astragal and the active door wears the hardware on the passive side. We see this constantly on postwar San Lorenzo homes where an original sliding patio door was swapped for a French set sometime in the 1970s or 1980s without addressing the foundation settlement. Our crews shim both jambs independently, then align the leaves so the lock stiles meet cleanly down the center. We carry Andersen and Marvin French door lines with prefinished options that hold up to the Bay’s salt air better than raw wood.
Bifold & Folding Doors
Interior bifold doors in San Lorenzo tract homes usually fail at the track and the bottom pivot bracket. The floor has settled, the header has shifted, and the panels now drag or bind. Most companies treat that as a door problem. It’s a framing problem. We re-level the track, reset the pivot brackets to the actual floor height, and if the panels themselves are shot, we quote replacement options from the manufacturer lines we’re authorized to install. On post-and-pier foundations, we set bifold tracks with a little more attention than average because the floor deflection between joists changes with the season.
Pivot Doors
Pivot doors are the exception in San Lorenzo, the high-end exception. They show up on remodels where a homeowner wants a statement entry on a 1950s ranch, often coordinated with an architect or designer. A pivot door needs a structural header and a frame that is absolutely plumb, because the entire weight of the slab hangs on the pivot hinges at top and bottom. On a clay-soil foundation, that means the opening gets re-squared and the header get reinforced before the pivot hardware is even ordered. We quote pivot door work with lead times fixed in writing. The slab itself, especially in an ES Windows or CGI line, can take weeks. The labor is not what drives the calendar. We make sure the homeowner knows that before the order is placed.
Arched & Custom Doors
Some of the nicer 1950s San Lorenzo ranches had arched front doors from the start, and homeowners doing a faithful remodel want that shape back. We cut and set arched jambs to match the original radius, coordinate with the door manufacturer on a slab that fits the opening, and handle the finish work. When someone asks whether we can match a custom arched entry to the rest of their postwar home, the answer is yes, and we’ll show them the exact spec sheet before fabrication begins. Custom millwork and specialty finishes are long-lead items. We price them that way, honestly.

Trusted Brands We Service in San Lorenzo
TruePane is an authorized installer for more than a dozen manufacturer lines. Around San Lorenzo, the brands that come up most on door work are Andersen for full-frame entry and swing doors, Marvin for French and custom configurations, and ES Windows for the occasional high-end pivot or architectural glass install. We also service and quote PGT and CGI for clients who want impact-rated doors, which makes sense in the flatlands where winter storms drive rain sideways off the Bay. We don’t push one manufacturer. We put two or three options on paper so a homeowner sees side by side what they’re actually getting, including warranty terms. Both warranty layers get registered in writing before the truck leaves the driveway. That’s the Keystone Standard.
Common Door Installation Problems We See in San Lorenzo Homes
- Racked rough openings from clay-soil settlement. The original 1950s door fit fine. Over sixty-plus years, the foundation shifted, the walls moved, and now a stock replacement door in the same nominal size binds on the latch side. We re-square the opening with shims before the jamb is set, which is standard practice for our San Lorenzo crews and the single biggest difference between a door that works for twenty years and one that rubs by spring.
- Corroded locksets and hinges from marine air. San Lorenzo sits close enough to San Francisco Bay that the air carries salt, and it roughs up uncoated door hardware faster than homeowners expect. Locksets get pitted, hinges stiffen, and screen door hardware on the older tract homes often has to be replaced at the same time as the door itself.
- Threshold rot from Bay humidity and San Lorenzo Creek moisture. Exterior door thresholds on the flatlands take on water from two directions: driving rain off the Bay during winter storms and persistent ground moisture near the creek. We routinely find sill plates that look fine on top but are punky underneath. A replacement door that sits on a rotted threshold won’t last, so we address the sill before hanging the new slab.
- Out-of-alignment handles and latches on sunken post-and-pier homes. The floor drops unevenly between piers on older San Lorenzo houses, which means the door slab tilts and the latch no longer lines up with the strike plate. Adjusting the hinges only works if the frame is still square. When it isn’t, the fix is re-hanging the door on a plumb jamb.
Pricing for Door Installation in San Lorenzo, CA
In San Lorenzo, a typical entry door replacement with a mid-range factory-finished slab and all necessary shimming and flashing runs $1,800 to $3,900, labor included. French door sets in this market run $3,200 to $7,500 depending on glass package and whether the opening needs moderate or significant re-squaring. A high-end custom pivot door with an ES Windows or CGI slab starts around $6,000 and goes up from there, because the door itself is the long-lead item and the engineering is real. Interior bifold or swing door replacements with new track and trim run $400 to $1,200 per opening. These are line-item quoted prices, not round numbers pulled at the kitchen table. A fixed price in writing means no change order surprises when the opening is found to be out of plumb, which in San Lorenzo is not an if but a how much. Call (888) 635-0804 for a free estimate. We’ll walk the openings with you and put the numbers on paper.
One thing we tell every San Lorenzo homeowner during a quote: on this postwar tract housing, lead times on the high-end stuff, not labor, set the calendar. A custom prefinished slab or an arched unit from a manufacturer line can take six to ten weeks. We fix the price before the order is placed, in writing, with the manufacturer’s current lead time attached. The Done Right Promise covers everything we install, and both warranty layers get registered in writing before we leave the driveway.

FAQs - Door Installation in San Lorenzo
San Lorenzo was built almost entirely between 1945 and 1960 on expansive clay soils, and nearly every original rough opening has racked out of square over the decades. A stock 36-by-80 door will slide into a truly square opening without complaint. In a San Lorenzo tract home, the jambs have drifted with the foundation, so we shim each opening back to plumb and level before the new jamb is attached. Installers who skip this step end up with a door that binds on the latch side within months. Call (888) 635-0804 and we’ll square your opening as part of the install.
The Bay puts salt in the air, and San Lorenzo’s flatlands sit close enough to receive it daily. Uncoated steel hinges and locksets pit and rust faster here than in inland East Bay cities like Castro Valley or Dublin. We recommend marine-grade or factory-finished hardware on exterior doors, and we replace corroded hardware whenever we hang a new door because it usually fails within a few years of the install anyway. The estimate covers it.
Six to ten weeks for most custom prefinished slabs and arched units, sometimes longer for specialty architectural glass from ES Windows or an impact-rated CGI line. The lead time is set by the manufacturer, not by our schedule. We state it in writing at the time of quote, and we fix the price before the order is placed. If you need a door sooner, we can usually get a stock size on the calendar within two weeks. Call (888) 635-0804 for a current lead-time estimate on the line you’re considering.
In most Alameda County flatlands jurisdictions, a like-for-like replacement door in an existing opening does not require a permit. If you’re enlarging the opening, adding a pivot door that changes structural loading on the header, or altering an exterior wall, a permit is typically required. We can tell you during the estimate whether your project falls into the permit category, and we pull the permits and schedule inspections when needed. We’ve done it many times on San Lorenzo remodels.
Yes. We template the existing or original arched opening and order a door to that radius, with the finish matched to the era of the home. Arched doors on San Lorenzo ranches were often a single plank or simple rail-and-stile construction, and we can replicate that look in a modern, weather-sealed unit. We’ll show you the manufacturer spec sheet and a drawing before fabrication. Estimates are free, and the quote is fixed in writing.
If you live in San Lorenzo and you’ve been putting off a door that sticks, drags, or lets the Bay air through, call us at (888) 635-0804. We’ll come out, measure the openings, point out what’s square and what isn’t, and put a fixed price on paper. No pressure, no surprise line items. Done right, in writing, with a warranty registered before we leave the driveway.
