Fast, Reliable Custom Windows & Doors Across San Bernardino

Custom window and door work in San Bernardino starts with a question most contractors never ask: what did the Cajon Pass wind do to this opening? We measure every rough opening twice, check the jamb for rack, and look at how the existing unit was flashed before we quote anything. A typical custom window replacement in San Bernardino runs $850-$2,400 per opening, and a custom door replacement usually lands between $1,600 and $4,200, depending on size, glass spec, and whether the framing underneath is still square. Call (888) 635-0804 and we’ll come put numbers on paper before you spend a dollar.

Why TruePane Windows & Doors Is San Bernardino’s Preferred Custom Windows & Doors Company

We’ve spent years answering calls from homeowners in San Bernardino who are tired of fogged glass, doors that bind in July, and contractors who disappear after the check clears. Dale Kessler founded this company in 2008 on a rule that still hangs in our shop: if the pane is not true, the job is not done. That means we re-plumb a racked jamb instead of forcing a new door into it. We register both warranty layers in writing before the truck leaves your driveway, and every job carries our Done Right Promise. No paperwork fights. No arguing. If it’s not right, we make it right.

Our technicians are background-checked, uniformed, and trained the way a glazier’s apprentice should be: on real houses, under a journeyman, until the work is second nature. When you call, a live person answers, 24 hours a day, 7 days a week. Not a voicemail tree. Not a callback form. A person who can schedule your estimate and answer a straight question about glass packages.

We know the housing stock here. We know that a 1950s rancher off Highland Avenue has different framing realities than a 1970s split-level near Perris Hill Park. That local knowledge changes how we quote, how we flash, and how long the job takes.

Our Custom Windows & Doors Services in San Bernardino

Here’s what we do most often for San Bernardino homeowners, and what each job actually involves when the wall gets opened up.

Custom Shape Windows

Arches, radius tops, trapezoids, half-rounds, octagons. San Bernardino’s mid-century homes often have a picture window or a front-facing accent window that’s no longer manufactured in the original size. We build custom units to match the opening, not the other way around. In San Bernardino specifically, we pay extra attention to the upper portion of the frame, because the sustained wind load from Cajon Pass tends to stress the apex of arched and radius units more than square ones.

Commercial Storefront Glazing

For storefronts along Highland Avenue, Baseline Street, and the downtown corridor, we replace tempered glass, repair aluminum storefront frames, and upgrade to energy-efficient insulated glass that holds up to the San Bernardino sun. The same wind that racks residential door frames also works on commercial storefront headers, so we inspect the header and jamb connections before we set any new glass.

Curtain Wall Systems

For larger commercial and multi-story buildings in San Bernardino, we design and install curtain wall systems that meet Climate Zone 10 fenestration requirements. These are engineered assemblies, not off-the-shelf window replacements. We work with the manufacturer’s engineering team on wind load calculations specific to the Cajon Pass exposure, because a curtain wall that works in Riverside won’t necessarily hold up to what San Bernardino gets.

Architectural Grilles & SDLs

Simulated divided lites and architectural grilles give a custom window the look of true divided light without sacrificing energy performance. We install SDLs in both interior and exterior configurations, matched to the original sightlines of the home’s era. On San Bernardino’s 1940s and 1950s bungalows, we match the original muntin profiles so a replacement doesn’t look like a modern insert wearing a costume.

Oversized Glass Panels

Fixed picture windows, glass walls, and large-format patio door panels. This is where San Bernardino’s combination of heat and wind really tests the spec. We use low-E coatings with a low solar heat gain coefficient because Climate Zone 10 compliance demands it, and we size the tempered glass to the actual wind load the opening will face. When we replace an oversized sliding patio door facing the mountains, we check the header and the sill for sag before the glass goes in.

Trusted Brands We Service in San Bernardino

We’re an authorized installer for more than a dozen manufacturer lines, and we quote them side by side on paper so you can see exactly what you’re buying. For San Bernardino’s climate, we often recommend CGI for impact-rated units, ES Windows for custom sizing and narrow sightlines on mid-century replacements, and CWS for architectural-grade storefront and curtain wall work. Because we stock local parts and work directly with these manufacturers, we’re not waiting on a distributor in another state to ship a replacement sash to San Bernardino. That keeps turnaround reasonable, even when a custom unit needs to go back for warranty work under our Keystone Standard.

Common Custom Windows & Doors Problems We See in San Bernardino Homes

  • Racked door frames from Santa Ana wind events. The Cajon Pass funnels wind directly into downtown San Bernardino with more force than Riverside or Fontana see. Over successive seasons, door jambs get pushed out of square. A new pre-hung door cannot be installed correctly until the jamb is re-plumbed, and skipping that step is how you end up with a door that binds in July and won’t latch in January.
  • Failed seals on original insulated glass units. If you see fog between the panes, the argon is gone. In San Bernardino’s 105-110°F summers, a failed IG unit lets a measurable amount of solar heat through, and your air conditioner is paying for it. On many original units from the 1960s and 1970s, the seal strip has degraded to powder.
  • Undersized or deteriorated framing around original single-pane windows. Many San Bernardino homes built between the 1940s and 1970s still have the original aluminum single-pane windows, and the wooden rough openings have had decades of deferred maintenance. We regularly find sills with rot, headers that were never sized correctly, and openings that have drifted. Custom-sized replacements often require reframing before the new unit goes in.
  • Dust and particulate intrusion during wind events. The mountain bowl around San Bernardino traps particulate pollution, and when the Santa Anas blow, that dust finds every gap in an old window or door frame. Airtight sealing is not just an energy measure. It’s a genuine indoor air quality issue for people living with respiratory conditions.

Pricing for Custom Windows & Doors in San Bernardino, CA

Here are real numbers for the San Bernardino market, based on what we’ve quoted and installed across the 92401 zip and surrounding neighborhoods over the past several years.

  • Custom shape window (arch, radius, trapezoid): $1,100-$2,800 per unit, depending on glass package and whether the frame needs re-plumbing.
  • Standard custom-sized replacement window: $850-$1,600 per opening for vinyl or aluminum-clad; $1,400-$2,400 for fiberglass or wood.
  • Custom entry door replacement: $1,600-$4,200, depending on material, glass lites, and whether the jamb needs re-plumbing after wind damage.
  • Oversized fixed glass panel or picture window: $1,800-$5,500, heavily dependent on tempered glass requirements and wind load engineering.
  • Architectural grilles and SDLs: Add $120-$400 per window, depending on pattern and interior versus exterior placement.
  • Storefront glazing (commercial): $45-$90 per square foot for insulated glass replacement, plus any framing repairs.

What moves the price is what we find when the old unit comes out. If the opening is square and the framing is sound, the job is straightforward. If the Cajon Pass winds have racked the jamb or the original sill is rotted, that work gets priced into the allowance before we start. We write every allowance into the contract up front, and every surprise is priced and approved in writing before we touch it. Call (888) 635-0804 for a free estimate. We’ll quote it on paper, line by line.

How Cajon Pass Changes a San Bernardino Window or Door Job

This is the part that only applies to San Bernardino. The city sits at the mouth of Cajon Pass, which acts like a nozzle aimed at the valley floor. When a Santa Ana wind event kicks up, the pass funnels high-velocity, superheated desert air directly into downtown and the surrounding neighborhoods with an intensity that Riverside and Fontana simply don’t experience. Window seals, weatherstripping, and door frame alignments take repeated stress every wind season, and that stress shows up as a very specific failure pattern: racked door jambs, stripped hinge screws, and IG unit seals breached from frame flex.

Here’s what that looked like on a recent job. In a 1960s home in the 92401 zip, our crew found the original single-pane aluminum windows had racked frames after years of Cajon Pass wind load, and one double-hung sash had dropped from its jamb. We re-plumbed the opening, replaced the failed insulated glass unit with a ViewLux low-E argon-filled casement, and used flashing tape around the new fusion-welded frame to stop the seasonal dust and heat intrusion. That’s not a repair you can do from the outside with a caulk gun. It required taking the unit out, inspecting the framing, and doing the work in the opening.

It’s also why we always check the rough opening before we quote a custom window or door in San Bernardino. If the jamb is racked, the new unit will never sit square. Re-plumbing is a repair step we do here more frequently than in any other Inland Empire city we serve.

The Climate Zone 10 Reality

San Bernardino sits in California Building Climate Zone 10, which carries some of the most stringent Title 24 fenestration requirements in the state. Contractors must spec very low solar heat gain coefficient dual-pane or triple-pane units to pass energy compliance. This is a more demanding spec than what coastal LA projects require. Homeowners here are not choosing between “good glass” and “cheap glass.” They’re choosing between glass that meets code and glass that fails inspection. We spec to code on every job, and we pull the permits when the project requires them. If a wall is opened and outdated wiring or failed waterproofing is discovered, we stop, document it, and bring it to you in writing with a price. There’s no change order hidden in the middle of the job.

Trusted by homeowners across San Bernardino and surrounding areas.

★★★★★

"Our bay window had rotted at the sill and two other outfits wanted to talk us into a flat picture window instead. TruePane rebuilt the opening and matched the original look. Neighbors have knocked on the door about it."

Gene A. · Verified customer

"Two entry doors. Showed up when they said, second day was a half day like they said, and the painter they recommended confirmed the frames were dead plumb. The financing was explained in actual dollars, not a brochure."

Janet R. · Verified customer
