Fast, Reliable General Contractor Across Barstow
When you need a General Contractor in Barstow, you need someone who knows what’s underneath the surface before the first hammer swings. Most Barstow homes were built between 1950 and 1975, and they hold specific problems: the caliche hardpan that turns ordinary trenching into jackhammer work, wiring that predates grounding, and slab foundations that have shifted through decades of 110°F summers and below-freezing winter nights. We write a full price before work starts, and that price includes the realities of building in the Mojave. Call us at (936) 259-2607 and we’ll talk through what your project actually needs.
Why Penhallow Remodeling Is Barstow’s Preferred General Contractor Company
Barstow homeowners have been burned enough times: a verbal estimate that changed at the door, a crew that never showed, a repair that failed six weeks later. We handle it differently. Every project gets a written price before we start, a written 365-Day Done Right Promise, and a defined arrival window. If something inside that guarantee period fails, we come back and fix it at no charge. That’s the Kingswell Way, in place since 2004, and it applies to every job in Barstow, from a tub-to-shower conversion to a full General Contractor in Barstow project.
Trevor Nash leads our team, and he’s clear about what that means: background-checked, uniformed technicians on every job, a live person answering the phone 24/7, and materials that hold up to the desert. We install Cambria quartz, KraftMaid cabinetry, and James Hardie siding because those products carry their own warranties alongside ours. That matters when the Mojave heat and wind test everything exterior.
Hire a General Contractor in Barstow
Hire a General Contractor in Barstow and you’re hiring someone to manage the parts of a remodel most people only see after the walls are open. That means pulling San Bernardino County permits, scheduling the rough-in inspections, coordinating trades, and making sure the work that gets buried inside the walls was signed off before it got buried. For a Barstow homeowner, the first question isn’t “what will it look like” – it’s “what will you find when you open the wall, and how will you handle it?”
Here’s how we handle it: inspection first, allowances written into the contract, and any surprise priced and approved in writing before we touch it. A typical kitchen remodel in Barstow runs $14,000 – $45,000 depending on layout, cabinet line, and countertop material. A bathroom remodel runs $9,000 – $28,000. Those numbers include an allowance for what opening the walls reveals, because in a 1960s ranch, something always shows up.
Inspection Before the Contract, Not After
Before we write your price, we walk the property. We look at the panel, the foundation, the framing visible in the attic or crawlspace, and the condition of the slab. That’s how we catch the cloth-wrapped wiring and the failed shower pan before they become change orders in the third week of the job.
Written Allowances for What We Can’t See
No contractor can see through stucco. So we put a written allowance line in every Barstow contract for the work that only reveals itself during demo: wiring upgrades, framing repair, waterproofing replacement. When we open the wall and find something, we price it in writing and get your approval before touching it. The number on day one is the number on the invoice unless you approve a change.
General Contractor Services in Barstow
General Contractor Services in Barstow span the scope of work you’d expect: kitchen remodels, bathroom remodels, whole-home renovations, room additions, and the structural and mechanical upgrades that come with them. What’s less expected is the local layer underneath. When we bid a below-grade scope in Barstow, we price the caliche hardpan into the excavation from the start. A footing trench that reads standard on a plan becomes jackhammer or pneumatic-excavation work when the calcium-carbonate layer sits 12 – 24 inches below grade, which it does across large swaths of the Barstow basin.
That’s the difference between a contractor who knows Barstow and one who’s never dug here. The first price includes the caliche. The second price changes once the excavator hits it.
Kitchen and Bathroom Remodels
These are the jobs where opening the walls tells the real story. In a 1950s – 1970s Barstow ranch, we plan for outdated wiring, undersized framing where a header should carry the load, and waterproofing that failed years ago. We price those items as allowances up front and pull permits so the rough-in gets inspected while the walls are still open.

Additions and Structural Work
A home addition in Barstow runs $45,000 – $130,000, and the below-grade portion of that scope is where the caliche problem shows up first. We schedule footing and slab pours before dawn during summer months, when temperatures stay low enough to prevent rapid surface evaporation and premature curing. The concrete has to survive 110°F days and freezing nights, and that starts with the pour.

Trusted Brands We Service in Barstow
We stock and install materials from brands that stand up to the Mojave: Cambria quartz, KraftMaid and Wellborn cabinetry, Kohler and Moen fixtures, James Hardie siding, Belgard and Unilock pavers. For Barstow homeowners, we also keep Sakrete products on hand for slab and foundation repair work, because the caliche hardpan and freeze-thaw cycles make concrete repair a recurring need across the older housing stock. When you call about a repair, we can usually bring the right materials on the first visit instead of ordering and returning.
Common General Contractor Problems We See in Barstow Homes
- Cloth-wrapped wiring with no ground conductor. Homes built in the 1950s and 1960s across Barstow frequently still have this original wiring. Opening a wall for a kitchen or bath remodel triggers a code upgrade that a permit inspection will catch, so we plan for it and price it before we start.
- Undersized framing behind load-bearing walls. In older slab-on-grade ranches, we regularly find headers that were framed with undersized lumber that shouldn’t carry the load above. We stop, write the change order, and repair the framing before closing anything up.
- Failed shower pan waterproofing. The original shower pans in 1960s Barstow bathrooms often failed years ago, and the subfloor has been quietly softening ever since. We see it on nearly every bathroom remodel in the older tract neighborhoods.
- Caliche-driven foundation movement. The hardpan layer that underlies much of Barstow creates a rigid subgrade, and decades of thermal expansion and contraction in the slab show up as cracks and door misalignment. We assess the slab before we quote any addition or structural work.

What Opening Up an Older Barstow Home Actually Turns Up
On a 1962 slab-on-grade ranch off Rimrock Road, our crew opened the kitchen wall and found cloth-wrapped wiring with no ground, undersized wall framing where a header was supposed to carry the load, and a subfloor softened by a decades-old shower pan that had long since failed its waterproofing. We stopped the job, wrote a change order before touching anything, and priced the framing repair and rough-in upgrades in writing. Then we pulled permits so a San Bernardino County inspector could sign off on the wiring and plumbing while the walls were still open, not after we closed them. The finished KraftMaid kitchen landed inside the original kitchen remodel range because the surprise was approved in writing, not absorbed as a mystery.
That’s the single biggest reason a remodel quote moves in Barstow: the house has been hiding things since the Eisenhower administration. We don’t pretend otherwise. We build the inspection and the written allowance into the contract so the surprise has a process instead of a dispute.

FAQs About General Contractor in Barstow
Because most Barstow homes were built between 1950 and 1975, and the wiring, framing, and waterproofing from that era have been failing quietly behind the stucco for decades. We write allowances into the contract for exactly this work, so when we find it, we price it in writing and get your approval before touching anything. Call (936) 259-2607 and we’ll walk your property before you sign anything.
We price it into the excavation from the first bid. The calcium-carbonate hardpan sits 12 – 24 inches below grade across much of the basin, and it turns a standard footing trench into jackhammer work that can double cost and schedule on below-grade scope. A contractor who bids Barstow without accounting for caliche either hasn’t dug here or is planning to surprise you later. We don’t do either.
A permit gets you a San Bernardino County inspector looking at the wiring, plumbing, and framing while the walls are still open. That’s the rough-in inspection, and it’s the difference between work that was signed off and work that was buried before anyone saw it. We pull permits on every remodel, and we time the inspections so nothing gets closed up before it passes. Call (936) 259-2607 to talk through what your project would trigger.
Yes. Barstow has a significant share of manufactured and mobile homes, and they carry different structural and permitting rules than site-built construction. We assess each one against its specific standard before we write a scope, and we don’t apply site-built assumptions to a manufactured home. Call (936) 259-2607 and we’ll take a look.
We schedule concrete pours before dawn during summer months to prevent rapid surface evaporation and premature curing, and we spec fastening schedules for roofing and exterior cladding that meet San Bernardino County wind-load requirements. The schedule accounts for the desert; it doesn’t fight it. Call (936) 259-2607 to discuss your timeline.
