Why TruePane Windows & Doors Is Los Altos’s Preferred Door Installation Company
TruePane has spent more than four decades serving Bay Area homeowners, and in Los Altos that means working on homes where the land is worth more than the original structure. Dale Kessler founded this company in 2008 on a rule that still governs every install: if the pane is not true, the job is not done. That matters on a 1962 ranch near Foothill Expressway where the original aluminum slider track has bowed from thirty years of morning dew, and the homeowner is deciding between a standard replacement and a thermally broken Pella. We measure every opening twice, quote manufacturer lines side by side on paper, and register both warranty layers in writing before the truck leaves the driveway.
Los Altos homeowners tend to ask harder questions than most. They have seen a fogged seal, a door that binds in July, a contractor who disappeared. We answer the phone with a live person 24 hours a day, seven days a week. Our technicians are background-checked and uniformed. And every job carries the Done Right Promise: if it is not done right, we make it right, no paperwork fights, no arguing. The work is guaranteed for 90 days. Both manufacturer warranty layers are registered in writing, durations stated. That is The Keystone Standard, and it applies to every door we hang in Los Altos.
Our Door Installation Services in Los Altos
Entry & Swing Doors
A new entry door on a Los Altos ranch home is as much about thermal performance as curb appeal. The original doors on 1950s and 1960s homes are frequently hollow-core or single-panel wood with no weatherstripping left to speak of. We replace them with insulated steel or fiberglass doors that hold a seal against the morning marine layer and meet Title 24 requirements without guesswork. Pricing for a standard entry door in Los Altos typically lands between $1,800 and $4,500 installed, depending on the slab, the frame condition, and whether sidelights are involved.

Double & French Doors
Double French doors are a natural fit for Los Altos ranches that open to rear patios and gardens. The challenge is the opening itself: many original frames are no longer square after sixty years of soil settlement and dew-driven corrosion. We correct the framing before setting the door, then flash and seal properly so the door swings true in July and January alike. A double French door installation in Los Altos generally runs $3,500 to $8,000, with wood-clad and fiberglass lines at the mid to upper end.

Bifold & Folding Doors
Bifold and folding door systems are no longer a luxury upgrade in Los Altos. Homeowners renovating their original ranch homes routinely spec NanaWall or Fleetwood multi-panel systems as a standard replacement for the old aluminum slider. The engineering matters: these panels are heavy, the track must be dead level, and the rough opening has to be corrected for the system to operate without binding. We install bifold doors in Los Altos most weeks, and the labor on a ranch home with an out-of-square opening is real. Expect to budget $6,000 to $14,000 depending on panel count, glazing, and frame correction.

Pivot Doors
A pivot door is a statement, and Los Altos homeowners who invest in one expect it to operate flawlessly. These are custom-ordered, heavy, and hinge-bound to a floor mechanism that demands a precise subfloor and a plumb jamb. We handle the manufacturer coordination, the finish specifications, and the install. A custom pivot door in Los Altos typically starts around $5,500 for a standard-size slab and runs well past $12,000 for larger openings with custom millwork. We quote the full number in writing before ordering, so there are no surprises when the door arrives.

Common Door Installation Problems We See in Los Altos Homes
- Corroded original aluminum sliders. The east-side ranch homes built in the 1960s often have sliding door tracks that have bowed and corroded from decades of morning marine-layer dew. The rough opening is frequently out of square, which means the old door was never sealing properly even when new.
- Out-of-square rough openings. When a homeowner swaps a door without correcting the framing, the new door binds, leaks air, or fails to close flush. We see this constantly. The fix is re-planing the jamb and shimming the opening before the new door is set, and it adds labor that a cheap bid will not include.
- Skipped flashing tape on wide eaves. Los Altos ranch homes have broad overhangs that shed water close to the wall. If flashing tape is skipped behind the jamb, condensation and runoff get trapped and rot the aging wood frame. We flash every door opening properly before setting the unit.
- Mismatched seal performance. A homeowner replaces a slider but ignores the fogged single-pane windows next to it. The new door seals tight while the adjacent glass still sweats and condenses every morning. If you are renovating a wall, we check the full fenestration picture so you are not left with a half-done thermal envelope.
Pricing for Door Installation in Los Altos, CA
Entry and swing door replacements in Los Altos run $1,800 to $4,500. Double and French doors run $3,500 to $8,000. Bifold and folding door systems run $6,000 to $14,000. Pivot doors start around $5,500 and go up from there, with custom millwork and finish specifications driving the number. The hidden cost on east-side ranch homes is the framing correction: a bowed 1960s aluminum slider track almost always means an out-of-square rough opening, and fixing that before the new door is set adds real labor. We quote that correction in writing, upfront, so the price on the estimate is the price on the bill. Call (888) 635-0804 to schedule a free estimate, and we will measure the opening and give you a fixed number before any work begins.

FAQs - Door Installation in Los Altos
Your sliding door feels heavier in winter because the aluminum track and rollers on a 1960s Los Altos ranch home corrode and bow over time, and the morning marine-layer dew accelerates that corrosion. The track deforms, the rollers bind, and the door fights you. The fix is not lubrication. It is correcting the out-of-square rough opening and replacing the track and door as a unit. Call (888) 635-0804 for an exact diagnosis and a written quote.
Usually yes, but the rough opening has to be corrected first. The original aluminum sliders on east-side Los Altos ranch homes frequently sit in openings that have gone out of square from decades of soil movement and dew-driven corrosion. A Fleetwood multi-panel system needs a dead-level track and a plumb jamb to operate properly. We re-plane and shim the opening, flash it properly, and then set the new system. The door itself fits the existing hole in most cases. The labor to correct the frame is the part most homeowners do not expect. Estimates are free, and we will tell you the truth about your opening before any order is placed.
For Los Altos, argon fill is worth specifying. The town sits in the southern Bay Area’s marine-influence zone, where summer morning fog and overnight condensation are routine even in dry months. Dual-pane insulated glass with argon fill manages that condensation better than air-filled units and improves the thermal performance of the door. It is not a luxury add-on. It is the correct specification for a house that sees dew on the glass more mornings than not. We quote argon-filled units as standard on any Los Altos door replacement and register the manufacturer warranty for the sealed unit in writing.
Title 24 requires that any new or replacement door in Los Altos meet California’s energy efficiency standards, which include minimum U-factor and SHGC ratings for exterior doors. The original 1960s aluminum sliders and single-pane doors on ranch homes do not come close to these requirements. When we replace a door in Los Altos, we pull the permit, install a compliant unit, and close the permit with the inspection passed. The workmanship is covered by the Done Right Promise, and both manufacturer warranty layers are registered in writing before we leave the driveway.
The lead time on a custom pivot door is longer than the install because the slab is built to order: custom millwork, specialty glass, hardware finishes, and the pivot mechanism itself. That manufacturing run typically takes four to eight weeks depending on the line, while the actual installation is a one to two day job once the door arrives. The labor is not what sets the calendar. The factory is. We order the door the same week the contract is signed, price it in writing before any order is placed, and keep you updated on the schedule so the renovation does not stall waiting for a slab. Call (888) 635-0804 and we will walk you through the exact timeline for the door you want.
Our crew replaced a 1960s aluminum slider in a Los Altos ranch near Foothill Expressway with a thermally broken Pella fiberglass sliding door. The original track had bowed from years of dew, requiring us to re-plane the jamb and shim the rough opening before flashing tape and setting the new door to hold a tight seal. The homeowner was surprised to learn that the out-of-square frame, not the door itself, had been the cause of her persistent drafts.
