Fast, Reliable Windows & Doors Across Brentwood
Replacement windows in Brentwood run $4,500 to $15,000 for a typical home, and sliding patio doors run $3,000 to $10,000 depending on size and glass package. If your window or door opening has shifted because of Brentwood’s expansive clay soil, you’ll want a contractor who doesn’t just swap units but actually checks the rough opening before ordering anything. That’s what we do at Barrett & Sons Construction. Tom Barrett and his sons work these neighborhoods, they understand the soil movement out here, and they answer the phone at (877) 610-1318 when you call.
Why Barrett & Sons Construction Is Brentwood’s Preferred Windows & Doors Company
Brentwood is not San Ramon and it’s not Walnut Creek. The homes here were built fast, in big blocks, on soil that moves. We’ve been running crews through the Fairview subdivision, Garin Ranch, and the neighborhoods off Balfour Road long enough that we know what’s behind the stucco before we open the wall. When you call us, you get a live person. Not a call center. Tom publishes his name, his address, and his license number, and if something isn’t right after the job, he comes back. That’s the 90-Day Done Right Promise, written on every contract.
Brentwood homeowners tell us the same story over and over: a national company quoted one number on the phone and showed up with another, or a crew that couldn’t answer basic questions about permits. We don’t work that way. Every scope, every allowance, every price change arrives as a written change order before a single nail moves. The permit inspector works for you, not for me, and that’s fine by us. We pull permits on every eligible job and we stand there while the inspector signs off.
Our Windows & Doors Services in Brentwood
We handle the full range, but in Brentwood three things come up more than anything else: replacement windows, sliding and patio doors, and custom sizing. Here’s what that actually means in a 94513 tract home.
Window Replacement
Most Brentwood homes built between 1995 and 2008 came with builder-grade aluminum single-pane windows. After 15 to 20 years, the thermal seal fails. You’ll see fog between the panes, especially on west-facing elevations where afternoon summer heat pushes past 105°F. A sealed-unit swap is sometimes enough. Other times the frame is compromised and the whole window comes out. We’ll tell you honestly which one you’re looking at, and we’ll show you the condition of the opening before you commit to anything.
Door Installation
Front entry doors in Brentwood take a beating from the Delta wind and the afternoon sun. We install fiberglass and steel entry doors that hold their finish better than wood in this climate. But before we order anything, we check the frame for square. A door that rubs or won’t latch in winter is usually not a hinge problem. It’s slab movement. We’ll tell you that straight, because installing a new door in a racked opening just means you’ll be replacing it again in three years.
Sliding & Patio Doors
Sliding doors are everywhere in Brentwood’s newer subdivisions, and they’re frequent victims of the same soil movement. We install vinyl and fiberglass sliders from Simonton and Milgard, and we take the time to reset the rough opening with structural shims when it’s drifted out of square. Skipping that step is how you get a door that binds in July and leaks in January.
Custom Windows & Doors
When an opening has shifted enough, a factory-standard unit won’t fit. We order custom-sized windows and doors, often from PGT or Ply Gem, and we build the opening back to square before installation. For Brentwood homes on expansive Altamont-series clay, custom sizing isn’t an upgrade, it’s a requirement in certain parts of the house. We’ll tell you where you can use stock sizes and where you can’t.
Trusted Brands We Service in Brentwood
We install and service Simonton, Ply Gem, and PGT windows and doors, which means replacement hardware, rollers, and balance systems are available without waiting weeks for a special order. Milgard is another brand we work with regularly, especially for the Tuscany series that fits a lot of Brentwood’s 1990s and early 2000s floor plans. For a homeowner in Garin Ranch or the streets off Concord Avenue, that means we can usually identify the existing manufacturer, order the correct part, and get the repair done without replacing an entire unit that still has years left in it.
Common Windows & Doors Problems We See in Brentwood Homes
- Fogged glass from thermal seal failure. Builder-grade sealed units from the late 1990s and early 2000s fail predictably after 15 to 20 years, and west-facing windows go first because of Brentwood’s sustained summer heat. The fix is usually a new insulated glass unit, not a whole window.
- Out-of-square door frames and windows that bind in winter. Slab-on-grade homes on expansive clay move seasonally. A door that sticks in January and swings free in July is almost always slab movement, not a failing hinge. Reframing or shimming the opening is the real fix.
- Stucco cracking around window and door openings. Craze-cracking lets winter Delta rain reach the OSB sheathing underneath. Once that sheathing rots, the new window or door has nothing solid to fasten to. We repair the opening before we install anything.
- Patio door tracks that jam or leak. Sliding doors in Brentwood’s newer subdivisions sit on moving slabs. The track loses level, the panel drags, and water finds its way in during winter storms. Resetting the threshold and shimming the opening is standard work for us here.

HOA and Builder Warranty Questions in Brentwood
Because so much of Brentwood was built in master-planned communities, HOA architectural rules are a real part of this work. If you’re in a development with a design review committee, changing front window style or entry door color usually requires written approval before installation. We prepare the spec sheets, the dimensions, and the finish details the committee wants to see, and we’ve been through enough Brentwood HOA reviews to know what gets flagged. On the warranty side, if your home’s original 10-year structural warranty has expired, replacing windows and doors has no effect on it. If the home is still within the structural warranty period on the slab, we’ll tell you whether the movement we’re seeing is worth filing as a claim before we touch anything.

FAQs - Windows & Doors in Brentwood
Measure the diagonals of the rough opening from corner to corner; if the two diagonal measurements differ by more than a quarter inch, the opening is racked and a standard unit may not seat, seal, or operate correctly. We check this on every Brentwood job because slab movement is common in the local clay soil. Call (877) 610-1318 and we’ll measure your openings and tell you what’s needed before you order anything.
No, replacing windows does not void a structural warranty, and if the 10-year period has already expired, there’s nothing left to void anyway. Most Brentwood homes built in the 1990s and 2000s are well past that window. What’s more important is whether the opening we’re working in has structural movement that should be documented before installation. We’ll help you determine that.
A fiberglass sliding door or a vinyl slider with a low-E glass package handles Brentwood’s afternoon heat and winter wind best, because the frame won’t warp and the finish won’t blister the way a wood door will. We typically recommend Simonton or Milgard units for this exposure. The real question is the condition of the slab beneath the track, because that’s what determines whether the door will operate smoothly for years. Call (877) 610-1318 for a free estimate and we’ll assess the whole opening.
In most Brentwood communities with a design review committee, yes, you need written approval before changing the visible style of front-facing windows or the front entry door. We prepare the specification and finish details the committee requires and we’ve handled approvals in several of the city’s larger developments. We’ll tell you at the estimate whether your particular HOA requires submission, and we’ll handle the paperwork.
Winter rain swells the expansive clay under your slab, and the slab heaves just enough to rack the door frames. In summer the clay dries and shrinks, the slab settles back, and the doors swing free. The pattern alone is a reliable sign of seasonal slab movement, not a hinge or latch problem. In the Fairview subdivision, we replaced a 1998-era sliding patio door that had racked three-eighths of an inch out of square from slab settlement; we reset the opening with structural shims and installed a Milgard Tuscany series door. The homeowner’s builder warranty had expired, so no permit conflict arose. If your doors are doing this, call (877) 610-1318 and we’ll take a look.
