Why Concord Homeowners Choose Barrett & Sons Construction
Founded in 1998, Barrett & Sons is owner-operated, and that matters in a city like Concord. When we work a kitchen remodel near Todos Santos Plaza or a roof replacement in the Holbrook Heights tract, the crew includes one of Tom’s sons. You’ll see the same faces from the first estimate to the final inspection. Our home page lists what we stand for, but here’s the short version: every scope change arrives as a written change order before work happens, every eligible job gets permits pulled and inspections signed, and every completed job carries our 90-Day Done Right Promise in writing. Homeowners in the Monument Boulevard corridor and the Clayton Valley side of town have hired us for exactly these reasons. They’ve been burned by outfits that promised one thing and billed for another. We put it on paper first.
Construction Services We Offer in Concord
Kitchen Remodeling
Concord’s 1950s and 1960s ranch homes often have original layouts that waste space and fight modern living. We plan kitchens around how your family actually cooks, with KraftMaid cabinetry and Cambria countertops when you want brand-name materials you can look up. Learn more about our Kitchen Remodeling in Concord.
Bathroom Remodeling
Older Concord slabs can complicate bathroom drain relocations, but we’ve handled enough of them to know what the soil does and when to plan around it. We install name-brand fixtures from Sterling and Grohe, and we never hide a plumbing surprise from you. Learn more about our Bathroom Remodeling in Concord.
Roofing
Concord summers over 100°F and fall Diablo winds punish roofing materials faster than most homeowners expect. We install GAF and CertainTeed systems with the exposure and ventilation details this climate demands. Learn more about our Roofing in Concord.
Windows & Doors
Pre-Title-24 insulation and single-pane Windows & Doors - Concord are common in older tracts, which means real heat gain and real energy loss. We install Andersen and Marvin products sized and flashed correctly for stucco exteriors.
Fence Installation
Concord’s zero-lot-line ranchers and hillside lots create boundary questions that matter before the first post hole goes in. We locate property lines, pull permits when required, and build fences that survive wet winters and dry summers.
Driveway & Pavers
Expansive clay soil under Concord slabs is the same soil under your driveway. We plan paver and concrete work with base depths and drainage details specific to Diablo Valley ground conditions. Belgard and Techo-Bloc are our standard hardscape lines.
Home Additions & ADU
Concord’s ADU rules make secondary units feasible on many lots, but grading and soil movement on slopes require attention before plans are final. We handle the full scope: design coordination, permits, foundation, framing, and finishes.
Neighborhoods We Serve in Concord
Our crews work throughout Concord, and we typically arrive for estimates within a day or two of your call. We know the streets, the soil, and the building styles in each area.

Why Concord’s Climate and Housing Affect Construction
Concord sits in the interior Diablo Valley, where summer temperatures regularly climb past 100°F and fall Diablo wind events send hot, dry gusts through the canyons. That combination bakes roofing underlayment, fades exterior paint, and stresses any material exposed to the sun. It’s not the mild coastal climate you get in Oakland or along the Bay shoreline. Contractors who treat Concord like just another East Bay city are missing the point. The heat and wind cycles here shorten the life of cheap materials and reward homeowners who choose Concord Roofing with GAF systems, premium window frames, and proper exterior flashing. And then there’s the soil. Concord’s older tracts were built on Montmorillonite clay that shrinks in summer and swells in winter. A slab that looks fine in February can show fresh movement by late August. Seasonal timing of concrete and foundation work matters here in a way it doesn’t in most neighboring cities.
Concord is also home to the former Concord Naval Weapons Station, nearly 5,000 acres now being redeveloped as the Villages at Concord. That project is generating a pipeline of grading, site prep, and new construction unlike anything else in the East Bay right now. At the same time, Concord’s dominant housing stock of 1950s through 1970s slab-on-grade tract homes sits directly atop that expansive clay. Foundation remediation, structural repair, and re-roofing are not occasional requests here. They’re persistent local demands. We see it every week when we walk a 1960s rancher near Monument Boulevard and find slab cracks that have nothing to do with earthquakes. The soil dried out, contracted, and the crack followed. It’s a Concord problem, and we plan for it.

FAQs About Construction in Concord
Most Kitchen Remodeling - Concord projects run between $35,000 and $85,000 depending on footprint, cabinet line, countertop material, and whether you’re moving plumbing or walls. Homes in the older tracts near Monument Boulevard sometimes need additional slab or framing work that coastal cities don’t, and that shows up as a line item. Call (877) 610-1318 for a written estimate, free of charge.
Only if you change the scope, and even then, you’ll receive a written change order before any new work begins. We don’t do verbal agreements followed by surprise invoices. The price we quote is the price we build to, and any allowance adjustment is documented on paper first. That’s the whole point of hiring Barrett & Sons instead of an outfit that quotes one number and bills another.
Yes. Every eligible job gets permits pulled and inspections signed. The permit inspector works for you, not for us, and that’s exactly why we like having him on site. Some contractors tell homeowners permits are optional. They’re not, and skipping them can create problems when you sell the house. We don’t skip them.
An ADU typically runs five to nine months from permit approval to final inspection, depending on site conditions and the scope of civil work. Concord’s expansive clay sometimes means additional grading or foundation steps, and we’d rather do that work correctly than rush the schedule. Your written estimate includes a project timeline.
Concord’s older slab-on-grade homes sit on Montmorillonite clay that shrinks during hot, dry summers and swells in wet winters. That seasonal movement cycles foundation cracks year after year, independent of any seismic activity. Contractors working the tracts near Monument Boulevard and east of I-680 see this constantly. It’s a local soil condition, not a construction defect. If you want an honest assessment of your slab, call (877) 610-1318 and ask for a second opinion on any written estimate you already have.

What Concord Customers Say
"Came back a year later to sort a door that had dropped as the frame settled. No charge and no argument about whether it was covered."
- Thaddeus Oyelowo"Addition over the garage matched the original roofline and brickwork so closely that visitors do not realise it was added. He tracked down the closest brick he could find rather than settling."
- Gideon Stroud"The bathroom was finished on the day he said at the start, which nobody had led me to believe was possible."
- Loretta Vanterpool
