Fast, Reliable Custom Windows & Doors Across Brentwood

Custom window and door work in Brentwood, CA is not the same job it is over in Walnut Creek or Oakland. The housing stock here is younger, built fast between 1995 and 2008, and it is now aging in predictable, expensive ways. We see the same failures repeat across the subdivisions near Balfour Road and Sand Creek Road: fogged glass on west-facing elevations, weatherstripping that has turned brittle under 105°F heat, and framing that was undersized on day one. TruePane Windows & Doors has been doing custom replacements and retrofits in Brentwood long enough to know what is behind those stucco walls before we open them. If you are planning custom windows or doors, call us at (888) 635-0804 for a free estimate. We measure every opening twice, quote manufacturer lines side by side on paper, and register both warranty layers before the truck leaves your driveway.

Why TruePane Windows & Doors Is Brentwood’s Preferred Custom Windows & Doors Company

We are not a franchise that parachuted into eastern Contra Costa County last spring. Dale Kessler founded TruePane in 2008 on a rule that still sits on the whiteboard: if the pane is not true, the job is not done. That standard governs every custom Custom Windows & Doors project we take on, and it is why Brentwood homeowners keep our number in their phones long after the first job is finished.

Our technicians are background-checked and uniformed. They show up when they say they will show up. They work in your home the way they would work in their own mother’s house. And when a Brentwood customer calls with a question after install, a live person answers the phone. Not a voicemail tree, not a callback form. That is the standard we have held since 2008 of community service, and we do not intend to loosen it now.

Brentwood residents have come to expect a certain kind of company. One that sponsors county fairs and church roof funds, hires local apprentices and trains them into journeymen, and acts like it plans to be in town in thirty years. That is us. We serve Custom Windows & Doors in Brentwood as a local crew, dispatched from our San Francisco Bay Area office, with the parts, permits, and manufacturer relationships already in place.

Our Custom Windows & Doors Services in Brentwood

Custom work is not off-the-shelf work. It requires a shop that can fabricate to odd angles, handle oversized glass safely, and respect the architectural language of the home. These are the custom services we most often perform in Brentwood’s planned subdivisions and the older ranch-style homes scattered east of town.

Custom Shape Windows

Arched, radius, trapezoid, octagon, quarter-round. Brentwood’s 1990s and 2000s tract homes often included a single decorative shaped window over an entry or staircase, and those units are now failing seals or showing frame rot around the jamb. We template each opening by hand, order the custom insulated glass unit to the eighth of an inch, and install it with flashing tape rated for sustained heat. A typical custom shape window replacement in Brentwood runs $900 to $2,400 depending on size, glass package, and whether the rough opening needs reframing. The shaped unit is factory-welded, never site-glued, so the seal holds past the manufacturer warranty.

Custom Shape Windows

Commercial Storefront Glazing

Brentwood’s retail strips along Balfour Road and Sand Creek Road include storefronts that are now two decades old. Failed thermal seals, impact cracks, and outdated single-pane entries are common. We handle storefront glazing for small commercial properties in Brentwood, including door closers, panic hardware, and tempered or laminated glass replacement. Storefront glazing in Brentwood typically runs $35 to $65 per square foot for standard replacement, with custom door or hardware work quoted as a line item. We schedule commercial work around your operating hours, not ours.

Commercial Storefront Glazing

Curtain Wall Systems

Larger custom projects, including some of the newer commercial construction along Brentwood Boulevard, call for curtain wall systems that anchor glass to structural members rather than conventional framing. We work with architects and general contractors on curtain wall design, fabrication, and installation. For residential applications, interior glass walls and glass railing systems fall into this category. A curtain wall build in Brentwood typically starts at $85 per square foot and rises with hardware finish, thermal break requirements, and engineering. Every system is engineered and permitted, never improvised.

Curtain Wall Systems

Architectural Grilles & SDLs

Simulated divided lites and architectural grilles are the single most common request from Brentwood homeowners who want to preserve the street-facing look of their HOA’s design standard while upgrading to modern low-E glazing. We install SDLs between the glass panes, so the exterior profile matches the original muntin profile, but the surface stays flat and cleanable. Bay and bow windows, double-hung units, and casements all accept SDLs. Grille packages add $45 to $120 per window depending on profile width and pattern complexity. They are measured and matched to your existing window style, not approximated.

Trusted Brands We Service in Brentwood

We are an authorized installer for more than a dozen manufacturer lines, including, and PGT. For Brentwood’s climate, we frequently recommend Milgard’s high-solar-gain low-E packages and PGT’s impact-rated lines for homes that catch full afternoon exposure. CGI and Ply Gem round out the options we quote side by side on paper, so you see exactly what each line costs and what each warranty covers. We stock common replacement parts locally for Brentwood customers, which means a broken sash or failed IGU on a line we carry can often be ordered same week, not same month.

Common Custom Windows & Doors Problems We See in Brentwood Homes

Every city has a signature failure pattern. Brentwood’s is no mystery to us. Here is what we repeatedly find when we open up walls and trim in this town’s tract-home stock:

  • Failed IGU seals on west-facing windows: Afternoon sun hits unshaded stucco walls directly at 105°F and superheats the window cavity. Add the delta breeze dropping evening temperatures 25 to 35 degrees in a few hours, and the glass cycles through thermal expansion that the original builder-grade units were never rated to handle. Fogged glass at 10 to 12 years is the predictable result, well ahead of warranty expectations.
  • Undersized framing and failed waterproofing hidden behind the trim: The window may look fine from the outside, but the rough opening was often framed tight, not square, and flashed with the cheapest material available in 2003. Once we open the wall, the real scope of the job comes into view.
  • Outdated wiring that triggers permit-driven electrical upgrades: Custom window retrofits in Brentwood tract homes frequently expose wiring that is no longer code-compliant once the wall is open. The permit triggers the upgrade, and that has to be priced into the job before we touch anything.
  • UV-degraded weatherstripping and flashing tape: Hot Diablo winds bake exterior seals until they crack and curl. Air and water then find their way around jambs and sashes, and the homeowner notices a draft in winter or a mildew smell after rain. We replace degraded materials with products rated for sustained inland heat.

Pricing for Custom Windows & Doors in Brentwood, CA

Here is what custom work actually costs in Brentwood as of 2026. A single builder-grade window replacement typically runs $600 to $1,200, but full custom units with high-solar-gain low-E glass and SDLs run $1,800 to $4,000 installed. Custom shape windows land between $900 and $2,400. Oversized glass panels, such as a large fixed picture window with tempered glass, run $2,500 to $6,000 depending on square footage and whether the opening needs structural reframing. A full-home replacement on a typical 2,000 to 3,500 sq ft Brentwood tract home with 15 to 22 windows falls between $18,000 and $45,000 before any framing, electrical, or waterproofing allowances are written in.

We write allowances into the contract for exactly the things we expect to find behind those walls: bad framing, failed flashing, outdated wiring. If the allowance is not needed, you keep the money. If the scope expands, you approve a written change order before we proceed. Call (888) 635-0804 to schedule a free estimate. You will get a line-item quote on paper, no vague ballpark.

Trusted by homeowners across Brentwood and surrounding areas.

★★★★★

"Impact windows on the whole house. They handled the permit, the inspection, and gave me a folder with every approval number for the insurance company. My windstorm premium dropped enough to notice."

Bill T. · Verified customer

"Whole-house window replacement at 71 years old is not something you want to do twice. Dale walked the house himself for the quote. Crew was the same three men all four days, and the foreman knew every window by room."

Pat and Ray L. · Verified customer
