AfterWindow Company in Brentwood, CA
Juniper Windows & Doors is the window company Brentwood homeowners call when they want a written price before any work begins. We handle window replacement, new window installation, and door replacement across Contra Costa County’s fastest-growing corner, where summer heat and Delta winds put real stress on seals, frames, and hardware. If you’re shopping for impact-rated glass or a front door that actually seals, call (682) 281-2168 and we’ll walk you through what your project costs in Brentwood.
Why Brentwood Homes Are Different
Brentwood’s housing stock spans three distinct eras, and each one fails differently. The 1990s and early-2000s subdivisions around Garin Ranch and Apple Hill Estates are full of original aluminum-frame windows that now sweat in winter and leak conditioned air all summer. Older homes closer to downtown, built in the 1950s through 1970s, often sit on pier-and-post foundations that shift with Brentwood’s clay-heavy soil – which means doors that once latched cleanly now stick or gap. Newer builds in the Vineyards and beyond tend to use builder-grade vinyl that fades faster under Brentwood’s 250-plus sunny days a year. Our crews see the same issues repeatedly: failed seals from Delta temperature swings, fogged double-pane units, and entry doors that swell shut every winter when the Tule fog rolls in off the San Joaquin River. We plan for all of it, including the HOA design-review requirements common in Brentwood’s master-planned communities.
Our Main Brentwood Services
Most Brentwood homeowners reach out about two things: replacing windows that have failed, and installing new windows or doors as part of a remodel or addition. Here’s what each involves in this city specifically.
Window Replacement in Brentwood
Replacing windows in Brentwood usually means pulling out original aluminum or early vinyl units and setting in new frames sized to the existing openings. The big local factor is Delta heat – south-facing and west-facing windows in neighborhoods like Garin Ranch take direct afternoon sun from May through October, which is why we recommend low-E and impact-rated glass more often here than in most Bay Area cities. Full details on pricing, product choices, and the replacement process are on the Window Replacement in Brentwood page.
Window Installation in Brentwood
New window installation is different from replacement: the openings don’t exist yet, or the rough framing needs to change. This comes up constantly in Brentwood additions, garage conversions, and new builds in the Vineyards and Trilogy communities. We coordinate with your framing crew, pull measurements twice, and order from our eight product lines so the new windows match what’s already on the house. For a breakdown of how new installation differs from replacement and what it costs, see Window Installation in Brentwood.
Door Replacement in Brentwood
Entry doors in Brentwood deal with two extremes: triple-digit summer afternoons and damp, fog-heavy winters. Wood doors swell and bind; steel doors rust along the bottom sweep; fiberglass holds up best, which is why we install more of it here than anywhere else in our Bay Area footprint. Whether it’s a front entry, a patio slider, or a French door, we quote a fixed price and stick to it. Read Door Replacement in Brentwood for full door pricing and options.

Prices in Brentwood push toward the higher end when a home has custom sizing, stucco exterior work, or HOA-mandated product specs. Brentwood’s newer subdivisions often require specific frame colors and grid patterns, which can add 10 – 15% to material cost. Whatever your number ends up being, you’ll see it in writing before we order anything – no allowances, no change orders, no surprises.
