Trusted Concord window installers, free in-home quotes, licensed & insured pros, workmanship warranty.
There are two US cities called Concord. This page covers Concord, California. If your home is in Concord, North Carolina, use our Concord, North Carolina window page instead , a different state energy code, a different permit office, and different local pricing apply, so the recommendations are not interchangeable.
Concord sits far enough inland that the bay stops helping by about noon. Summer afternoons reach 89 degrees in the Ygnacio and Clayton valleys while nights fall to the low forties in winter, and that spread is what tires out an old aluminum frame. Get the glass and the frame right and the west side of the house stops being a problem in August.
As the largest city in Contra Costa County, Concord is mostly a postwar suburb, and its windows tell you so. Dana Estates, Ygnacio Valley and the Monument corridor are full of 1950s and 1960s ranch and mid-century homes still running their first set of single-pane aluminum sliders. Around Todos Santos Plaza the stock is older again. You feel all of it as drafts in January and rooms that will not cool in July.
Concord is the largest city in Contra Costa County, in the East Bay inland from San Francisco. Its housing is largely postwar, mid-century ranches and tract homes around Todos Santos Plaza and the Concord and Clayton Valley neighborhoods, and its climate is classic inland California: hot, dry summers well above what the cooler coast sees, with mild winters. Sun and heat drive the window choice here. We fit Concord homes with a low-SHGC, spectrally-selective Low-E that blocks solar heat and glare, in a dimensionally stable frame, so a ranch home stays cool through a triple-digit Concord afternoon without punishing the electric bill.
In-house background-checked crews handle every install, and the measurer is on the job for the fitting too.
Written line-item pricing up front, including what a phased job costs if you split it across two visits.
Your installer pulls the permit through the City of Concord Building Division and manages Title 24 compliance for you.
Our installation is covered for life, and the manufacturer warranty backs the glass and moving parts.
Every style, built for Concord's climate.
Two sashes that slide vertically, easy to clean and a natural match for Concord's postwar ranch homes.
Cranks outward from a side hinge for strong airflow and a seal that holds through the daily heat swing.
Slides along a horizontal track, the standard replacement for the wide rear sliders in Dana Estates.
A single fixed pane with nothing to operate, ideal for a shaded elevation or a stairwell wall.
Multi-panel windows that project outward, adding floor space and depth to a long mid-century frontage.
Awnings vent from the top in winter rain, and garden windows create a sunny shelf above the kitchen sink.
For Concord's warm, sunny climate we most often install vinyl or fiberglass frames with Low-E 366 spectrally-selective glass.

Concord sits far enough inland for real summer heat, with cool nights and strong year-round sun. Solar control leads, and frame stability across a wide daily swing follows close behind. This is the package we fit on Concord homes:
| Spec | Recommended for Concord | Why |
|---|---|---|
| Glass coating | Low-E 366 spectrally-selective | blocks solar heat, keeps interiors cool |
| Frame material | Vinyl or fiberglass | mild, sunny climate, low expansion, long life |
| Gas fill | Argon | steadier indoor temps year-round |
| U-factor target | ≤ 0.28 | exceeds the California Title 24 requirement for your climate zone |
| SHGC target | 0.22 | beats the code cap, and it is what blocks the sun |
For Concord homes the Low-E 366 coating does the visible work, holding SHGC near 0.22 so afternoon sun stops loading up the living room. Vinyl and fiberglass also move far less than aluminum across a forty-degree daily range, which is exactly why the original frames in these tract homes leak now. Residential power in California averages about 36.1 cents per kilowatt-hour, so a lighter air conditioning load turns into real money across a Concord summer.
Window installation in Concord typically runs $600 to $1,000 per installed window, or $12,000 to $22,000 for a full home. Postwar tract homes are usually efficient jobs, because the openings are standard sizes and repeat across the house. Two-story homes in the hills above Clayton Valley can add access cost. With local home values near $720,000, a full replacement is a reasonable share of the property, and the quote you get is fixed and line-item.

We measure each opening in person and give you a written estimate, phased if you want the sunny side first.
Your windows are built to your exact openings, which matters even in a tract where sizes almost repeat.
Most Concord homes finish in one day, and we file with the Building Division ahead of the crew arriving.
We clean the work area, take the old frames away, and register your warranty before we go.
Concord requires a building permit for window replacement, and we file it through the City of Concord Building Division. Plan review tightens if you change the size of an opening, alter a bedroom window that has to satisfy egress rules, or modify a structural header. Every replacement unit has to meet California Title 24, which holds replacement fenestration to a 0.30 U-factor and a 0.23 SHGC, with a 0.40 U-factor allowed when the total replacement area stays under 75 square feet. That exception covers a lot of partial jobs in Concord, where homeowners often replace the sun-hit elevation first and come back for the rest. Your installer handles the permit and the inspection either way.
"Got three quotes in Concord. Theirs was the only one that explained the glass choice."
"The upstairs of our Clayton Valley place used to be unusable in summer. Not anymore."
"They worked around our schedule and finished the Dana Estates job in a single visit."

Yes. The City of Concord Building Division requires a building permit for window replacement. Your installer files it, meets Title 24, and schedules the inspection as part of the job.
For Concord's warm inland climate, we recommend Low-E 366 spectrally-selective glass with argon fill in vinyl or fiberglass frames at a U-factor of 0.28 or lower. Frame stability matters given the wide day-to-night swing.
Most Concord jobs run $600 to $1,000 per installed window, or $12,000 to $22,000 for a full home. Standard postwar tract openings keep labor efficient; hillside two-story access adds to it.
Residential power in California averages about 36.1 cents per kilowatt-hour. On a typical Concord home, efficient windows save about $546 a year on the ENERGY STAR published figure for this climate zone, or about $336 if you are replacing older double pane.
Yes, and many homeowners here do. Title 24 allows a 0.40 U-factor when the total replacement area stays under 75 square feet, so a west-elevation-first job is straightforward. We quote the phases separately so you can see what each one costs.
Yes. Every installer we match you with is licensed, bonded and insured in California, and their work carries a lifetime workmanship warranty from your installer alongside the manufacturer's warranty on the windows. We arrange your quote and the introduction; your installation contract is with the installer who does the work.
