AfterFast, Reliable General Contractor Across Vallejo
Hiring a general contractor in Vallejo means finding someone who understands what’s behind the walls of a house built in 1915, not just someone who can swing a hammer. Penhallow Remodeling serves homeowners across Vallejo with written pricing before work starts, background-checked crews, and a 365-Day Done Right Promise in writing on every project. Trevor Nash leads our team, and we coordinate scheduling from our San Francisco Bay Area office with crews working in Vallejo every week. Call (936) 259-2607 and a live person answers, day or night.
Why Penhallow Remodeling Is Vallejo’s Preferred General Contractor Company
Vallejo homeowners call us because we write down the price before we pick up a tool. That matters here more than almost anywhere else in the Bay Area, because opening up a 1920s Craftsman on Capitol Street or a post-WWII tract home near Hogan often turns up wiring, plumbing, and foundation issues that other contractors would bury in a surprise change order. Our General Contractor team walks every job with the permit requirements in mind, so the number you approve on day one is the number you can plan around.
We do not ask you to trust us on faith. Every project we take in Vallejo gets a written scope, a written price, and a written guarantee. The guarantee lasts 365 days, and if something fails inside that window, we come back and fix it at no charge. No re-inspection fee, no service call charge, no argument. That’s the Kingswell standard, and it has been since 2004.
Our crews arrive in uniform, background-checked, and on the schedule we gave you. Vallejo traffic across the Carquinez Bridge can wreck a timeline, so we build real arrival windows into the contract instead of promising a vague “sometime Tuesday.” A live person answers our phones 24/7, which means when you call at 7 p.m. to ask about the permit status on your Kitchen Remodeling in Vallejo, you talk to a person, not a voicemail.
Remodeling Contractor in Vallejo
Remodeling Contractor work in Vallejo almost always starts the same way: you call us about a kitchen or bath that feels dated, and we open up a wall to find what the house has been hiding since the Navy boom. Pre-1930 Victorians and Craftsman homes along Georgia Street and the historic downtown blocks were framed before seismic codes existed. Post-WWII tract homes built for Mare Island workers are now 70 to 80 years old, with galvanized plumbing and early-aluminum wiring that don’t meet today’s code. A kitchen remodel that starts at $14,000 – $45,000, or a small kitchen at $9,000 – $20,000, sometimes grows once the inspection reveals what’s behind the tile. We handle that by writing allowances into the contract up front, so a change order is priced and approved in writing before extra work begins, never after the fact.
Inspection Before Demolition
We won’t swing a sledgehammer on a Vallejo remodel until we’ve looked at what the wall is hiding. That means checking for knob-and-tube wiring, cast-iron or galvanized supply lines, and enough framing to carry the new load. The inspection takes time, but it’s the difference between a quote you can trust and a price that balloons after demo day.
Allowances Written Into the Contract
Older homes don’t surprise us, because we build line-item allowances for the likely discoveries: abatement, electrical rough-in, repipe work. When a change order comes, it’s a conversation and a written number, not a phone call asking for more money with no paper trail.
Licensed General Contractor in Vallejo
Licensed General Contractor work in Vallejo is about more than pulling a permit. It means understanding that a remodel on Mare Island or near the waterfront triggers a different set of requirements than a project up in Fairfield or Vacaville, and those requirements have real dollar figures attached. Home additions in Vallejo typically run $45,000 – $130,000, and ADU construction ranges from $90,000 – $220,000 depending on whether the parcel sits in a liquefaction zone that demands an engineered foundation. We coordinate the geotechnical report, the structural engineer, and the permit package so the whole thing moves as one job instead of a stack of surprises.
Permit-Ready Documentation
Vallejo’s building department wants to see the same things on every pre-1930 remodel: an asbestos survey, a lead-paint assessment, and a plan for bringing wiring and plumbing to current code. We assemble that package before the first inspection, because a permit that stalls costs you weeks and money. This is standard practice for us, not an afterthought.
Geotechnical and Foundation Work
Parcels near the Mare Island Strait, the waterfront, and the lower east side fall into mapped liquefaction and bay-mud zones. That means a geotechnical report is not optional, and the foundation design often has to be engineered rather than prescriptive. We order the report early, get the engineer’s stamp, and build that cost into the written estimate so it doesn’t ambush you at plan check.
Trusted Brands We Service in Vallejo
We install materials from brands that back their products with real warranties, because the products behind our guarantee have to be as solid as the promise itself. In Vallejo kitchens you’ll see KraftMaid and Wellborn cabinetry, Cambria and Silestone countertops, and Kohler or Moen fixtures. For whole-home envelope work we spec James Hardie siding, and for hardscape we work with Belgard and Unilock. Some Vallejo homeowners ask about prefab and panelized options from companies like Abodu, Cover, and Dvele for ADU and garage-conversion work on tight lots, and we’re comfortable coordinating with those systems where the site conditions allow. We keep common replacement parts sourced locally so a cabinet hinge or a shower valve doesn’t hold up your finish schedule.
Common General Contractor Problems We See in Vallejo Homes
- Knob-and-tube wiring still feeding active circuits. We find this constantly in the 1870s – 1920s housing stock, and it will not pass inspection once walls are open. The fix is a full electrical rough-in for the affected rooms, priced as a change order against the allowance.
- Galvanized supply lines corroded to the point of weeping. Vallejo’s marine air accelerates corrosion, and post-WWII tract homes with original galvanized plumbing often show pinhole leaks behind walls. A repipe is a common mid-remodel discovery, and we handle it with written approval before any drywall goes up.
- Foundation settling on bay-mud soils. Homes on the east side and near the Mare Island Strait sit on compressible soils, and decades of settlement show up as cracked footings and out-of-level floors. The fix is shoring and sometimes engineered piers, which is why the geotech report matters before you plan a kitchen.
- Marine-air corrosion on fasteners and flashing. The confluence of San Pablo Bay and the Carquinez Strait puts salt and moisture into every exposed metal surface. Standard galvanized hardware fails faster here, so we spec stainless or hot-dip galvanized fasteners and flashing rated for the environment.

FAQs About General Contractor in Vallejo
Because Vallejo’s pre-1930 Victorians and Craftsman homes and its post-WWII Navy tract houses were built before modern codes, so once a wall is open, the inspector sees wiring, plumbing, and framing that no longer meet current standards. Knob-and-tube wiring, galvanized pipes, and undersized joists are common discoveries. We handle this by writing allowances for these items into your contract up front, so any change order is a written conversation, not a surprise bill. Call (936) 259-2607 and we’ll walk your specific house before you commit to anything.
Almost certainly yes. Parcels near the Mare Island Strait, the waterfront, and the lower east side of Vallejo sit within mapped liquefaction and bay-mud zones, and the city will require a geotechnical report and an engineered foundation design before issuing the permit. We order the report early in the process so it doesn’t stall your schedule. The cost is a line item in the written estimate, and we’ll explain exactly what the engineer found before you approve the foundation scope.
Three things: the scope of work, the price, and the guarantee. The scope should name every room, every material, and every code upgrade the permit will require. The price should be a written number, not an estimate range you can’t hold anyone to. And the guarantee should say exactly what happens if something fails, for how long, and at whose cost. Our 365-Day Done Right Promise says if the work fails inside a year, we come back and fix it at no charge, and that’s in writing on every Vallejo job. Call (936) 259-2607 for a written quote that covers all three.
Vallejo sits where San Pablo Bay meets the Carquinez Strait, and the marine air corrodes standard galvanized fasteners, rebar, and flashing faster than inland Solano County. We spec stainless or hot-dip galvanized hardware on any exterior or moisture-exposed connection, and we choose flashing and anchor systems rated for that environment. It costs a little more up front and saves you a repair later. The same logic applies to cabinet hardware and plumbing fixtures near the water, which is why we default to brands like Kohler and Moen that stand behind their finishes.
Yes. Mare Island is one of the largest brownfield redevelopment projects in California, and any work inside the former naval shipyard involves historic preservation mandates for 19th-century brick structures, EPA cleanup coordination, and complex adaptive-reuse build-outs. We’ve worked within those constraints and understand that the permit path is different from a residential remodel on Georgia Street. We coordinate with the environmental consultants and historic review boards, and every cost is written down before we move a single brick. Call (936) 259-2607 and ask for Trevor, and we’ll tell you straight what your Mare Island project will require.
