AfterRemodeling Company in Concord, CA
Home remodeling in Concord typically runs $14,000 – $130,000 depending on scope, with whole-house projects and additions at the higher end and single-room updates at the lower. We’re Penhallow Remodeling, and we specialize in the kind of work these 1955 – 1975 ranch homes need: opening up kitchens closed off by load-bearing walls, replacing aluminum wiring before we hang new drywall, and managing asbestos abatement when we pull original floor tile. Our crews coordinate scheduling from the San Francisco Bay Area office and serve Concord directly. Call (936) 259-2607 to schedule your free estimate.
Why Concord Homes Are Different
The bulk of Concord’s housing stock is 1,200 – 1,800 square foot slab-on-grade ranch homes built during the post-WWII bedroom-community boom, many still running original framing, roofing, and electrical. That vintage means we regularly encounter aluminum wiring, single-pane jalousie windows, and asbestos in drywall texture and duct wrap, all of which require licensed abatement coordination before we can pull a permit for renovation work.
Concord sits inland in the Diablo Valley and hits 95 – 105°F in summer, significantly hotter than coastal Bay Area cities. That heat compresses exterior construction windows and demands specific concrete cure-time management that contractors working out of Oakland or Walnut Creek often underestimate. The sharp wet-dry cycle also drives the expansive Diablo clay soils to heave and shrink, stressing slab foundations and making repairs recurring rather than one-time. In older neighborhoods near downtown and along the Monument Corridor, we frequently find unreinforced slabs poured directly on expansive adobe clay with no vapor barrier, a combination that causes seasonal cracking, interior moisture intrusion, and mudsill rot that shows up in nearly every full renovation in those zip codes.
The Concord-Green Valley Fault zone runs through the city, and most of this housing predates modern seismic codes, making structural retrofitting and foundation work a defining pillar of local construction demand. Meanwhile, the planned redevelopment of the former Concord Naval Weapons Station, one of the largest urban infill projects in California, is generating a construction pipeline with no parallel in neighboring Walnut Creek or Pleasant Hill.
Our Main Concord Services
Concord homeowners call us most often for whole-home transformations and room-specific renovations. Here’s what each service involves locally.
General Contractor in Concord
As a general contractor in Concord, we manage the full sequence from permit pull to final inspection, coordinating abatement contractors for asbestos-containing materials, structural engineers for load-bearing wall removals, and PG&E for electrical service upgrades common in these 1950s – 1970s homes. We know the Contra Costa County permit office requirements and the specific inspection points that trip up out-of-area contractors. General Contractor in Concord
Bathroom Remodeling in Concord
Bathroom remodeling in Concord means working around galvanized steel plumbing, venting exhaust fans through original roof decks, and often replacing subfloors damaged by decades of moisture on those slab-on-grade foundations. We pull permits for plumbing and electrical changes and coordinate with the county on asbestos abatement when we remove original floor tile. Bathroom Remodeling in Concord
Kitchen Remodeling in Concord
Kitchen remodeling in Concord almost always involves opening up load-bearing walls between kitchen and living areas in these closed-off ranch layouts. We bring in structural engineers, install proper headers, and upgrade electrical panels to handle modern appliance loads. We also manage the asbestos abatement common in original drywall texture before we hang new rock. Kitchen Remodeling in Concord

Home Remodeling in Concord
Home remodeling in Concord means working with the specific conditions of this post-war housing stock: aluminum wiring that needs replacement before we add circuits, single-pane windows that make energy code compliance a real challenge, and expansive clay soils that stress foundations and flatwork on a seasonal cycle. We’re familiar with the permit requirements for structural work in Contra Costa County and the abatement protocols required when we disturb original materials. Home Remodeling is our core service, and we’ve developed specific workflows for the ranch homes that dominate Concord’s neighborhoods.
