AfterFast, Reliable General Contractor Across Lafayette
Finding a general contractor in Lafayette means finding someone who understands what happens when you open the walls of a 1960s hillside home. You get cloth-wrapped wiring, undersized framing, and the kind of surprises that turn a $30,000 quote into a $60,000 invoice if the contract wasn’t written right. Penhallow Remodeling handles that differently: we inspect first, write real allowances into the contract, and price every surprise in writing before we touch it. Call (936) 259-2607 for a free estimate, and we’ll tell you honestly what your remodel will cost before any work begins.
Why Penhallow Remodeling Is Lafayette’s Preferred General Contractor Company
Lafayette homeowners keep calling us back for one reason: we put the number in writing and stand behind it. Our General Contractor team works across Lafayette from Happy Valley Road to the hills above Acalanes High School, and we know what those houses hide. Reviews from Lafayette customers consistently mention the same things: we answer the phone, we show up in the window we gave, and when a surprise shows up mid-project, it gets priced and approved before anyone swings a hammer.
Trevor Nash leads every Lafayette job, and he’s the one walking your lot before the contract gets written. No sales rep passes you off to a stranger. Part of the Kingswell family of companies since 2004, each Penhallow location is independently owned and operated, and ours carries the same standing rule: a written price before work starts, a written guarantee on every job, and a 365-Day Done Right Promise that says if it’s not right, we make it right at no charge.
Response time matters when you’ve been burned before. We schedule Lafayette visits in a defined arrival window and send background-checked, uniformed technicians. When something goes wrong after the job closes, you call us, and we return for free during the guarantee period. No service call fee, no re-inspection charge.
Remodeling Contractor in Lafayette
A Remodeling Contractor in Lafayette takes your existing home and changes its layout, function, or finish without tearing it down. That’s kitchen remodels, bathroom remodels, whole-home reconfigurations, and the additions that make a 1,400-square-foot rancher work for a growing family. In Lafayette, almost every remodel also triggers Wildland-Urban Interface requirements once a permit touches exterior elements, so your contractor has to know the fire code as well as the framing code.
What does that mean for pricing? A kitchen remodel in Lafayette runs $14,000 to $45,000 depending on cabinet line, countertop material, and whether you’re moving plumbing. A bathroom remodel falls between $9,000 and $28,000. Whole-home remodels and additions climb from there, and we’ll walk you through every line item before you sign.
Kitchen and Bath Scope in Older Homes
Most Lafayette kitchens and baths sit in homes built between the 1950s and 1980s. That means galvanized supply lines, original drain stacks, and wiring that predates modern appliance loads. We write allowances for those conditions into every contract so the price you see on day one already anticipates what we’ll find on demo day.
Known Conditions, Written Beforehand
We walk the job with you before quoting. If we can see a cracked foundation stem wall or a roof with two layers of old shingles, that condition gets priced in writing. We don’t bury unknowns in change orders and hope you won’t notice.
Licensed General Contractor in Lafayette
A Licensed General Contractor in Lafayette carries the license, insurance, and bond required to pull permits, manage subs, and get your project through Contra Costa County inspection. That’s not a formality. Lafayette sits inside California’s Very High Fire Hazard Severity Zone, and the building department’s plan check process holds every job to Wildland-Urban Interface standards, even on interior remodels that touch exterior walls, vents, or roofing.
On a 1962 post-and-pier hillside home off Happy Valley Road, we opened a load-bearing kitchen wall and found cloth-wrapped wiring and undersized framing that no one could see at bid time. We had already written allowances for structural repair and a change order process into the contract, so our techs documented the rough-in, pulled the permits, and priced the framing and WUI-compliant vent upgrades in writing before the homeowner approved a single dollar. The job closed on a clear punch list, with inspection sign-off on the first pass.
Permits, Engineering, and the Code Triggers
Most Lafayette remodels need a permit. Once walls are open, building inspectors check wiring, shear wall nailing, hold-down hardware, and fire-rated assemblies. We schedule inspections, meet inspectors on site, and keep the project moving between each phase. Crews roll up shavings and still-moist latex paint if we’re handling demolition.
Seismic and Fire Code Upgrades
Lafayette’s hillside lots make seismic upgrades a genuine priority. Cripple walls, missing anchor bolts, and undersized shear panels are common in pre-1980 homes. We price those retrofits explicitly and coordinate with a structural engineer when the scope calls for it.
Trusted Brands We Service in Lafayette
We install materials that carry their own warranties because that’s what supports our 365-Day Done Right Promise. Cabinet jobs use KraftMaid or Wellborn. Countertops come from Cambria, Silestone, or Caesarstone. For exterior cladding and fire-resistant assemblies on Lafayette homes inside the WUI zone, we spec James Hardie siding and Sakrete concrete mixes. We keep local stock in Lafayette for common trim, underlayment, and flashing so short-turn punch list items don’t stall a closeout.
Common General Contractor Problems We See in Lafayette Homes
- Surprise change orders after demo. Contractors quote a fixed number before opening walls, then discover old wiring or rotted sheathing and hand you a bill you never approved. We write allowances for those conditions into the contract up front, and any change is priced in writing before we proceed.
- Skipping the VHFHSZ spec. Some contractors bid Lafayette jobs like they’re working in Walnut Creek or Concord. Then the roof, vents, or eaves get red-tagged at inspection for missing WUI compliance, and you pay twice for the same scope. We spec Class A roofing, ember-resistant vents, and non-combustible eaves from the start.
- Treating expansive clay like flatland soil. The adobe clay under many Lafayette hillside parcels swells and shrinks with every wet winter and dry summer. A conventional slab poured on that soil cracks within a season. We routinely recommend pier-and-grade-beam foundations or post-tension slabs based on Contra Costa County soils data.
- Unapproved foundation changes mid-project. Once demo exposes a cripple wall or a cracked footing, the structural scope changes. We handle the engineering review and permit revision so the additional work is priced and approved in writing before concrete gets poured.

FAQs About General Contractor in Lafayette
Yes. Once a permit is pulled and the scope touches any exterior wall assembly, vent, eave, or roof connection, the Lafayette building department applies Wildland-Urban Interface requirements regardless of whether the project started as an interior remodel. We spec those items from the beginning so the inspection doesn’t red-tag your job. Call (936) 259-2607 for an exact quote on your scope.
Cloth-wrapped or aluminum wiring, undersized floor joists, failed waterproofing around window and door openings, and occasionally asbestos-containing materials in older drywall compound or flooring. We factor those conditions into allowances in the contract, not as surprise change orders after the fact. We walk the findings with you and price the fixes in writing before work proceeds.
Most often because the contractor bid a fixed number without inspecting what’s behind the walls, then wrote change orders for framing repairs, wiring replacement, or WUI upgrades the homeowner never approved. We handle it differently: written allowances for known conditions, a written change order process for anything new, and your approval required before a dollar gets added. That’s the Penhallow standard, and it’s in writing.
You need a licensed general contractor. Hillside additions in Lafayette require structural engineering, grading plans, and Contra Costa County permits that a handyman cannot pull or close. The expansive clay soils on hillside parcels also demand foundation design that accounts for seasonal movement. Working without the proper license and permits puts the structural integrity of the addition at risk and complicates resale.
We start with the soils report and an engineer’s review of the existing foundation. If the lot sits on expansive adobe clay, we spec pier-and-grade-beam or post-tension slab design rather than a conventional slab. The foundation scope is priced in writing before demo begins, so you know the structural plan and its cost before walls come down. Call (936) 259-2607 to schedule a foundation review and free estimate.
