Why Penhallow Remodeling Sacramento Is Folsom’s Preferred General Contractor Company

Trevor Nash runs our team the way a contractor should: say the price before the work, show up in the window we gave, leave the place cleaner than we found it. That’s The Kingswell Way, and it’s been our operating standard since 2004. Folsom homeowners have told us the same story enough times that we know why they call: a verbal estimate that changed at the door, a crew that never arrived, or a repair that cracked six weeks after the check cleared. We write the number down, we write the guarantee down, and a background-checked, uniformed technician shows up when we said they would.
Every Folsom project gets the 365-Day Done Right Promise in writing. If something fails inside the guarantee period, we come back and fix it at no charge. No service call fee, no re-inspection fee, no argument. That promise applies whether we’re doing a $9,000 small bathroom remodel or a $220,000 detached ADU with county permitting.

Remodeling Contractor in Folsom
A Remodeling Contractor in Folsom should know the difference between city and county jurisdiction before you spend a dime, because acreage lots in Folsom often fall under Sacramento County rules even when the mailing address says Folsom. That changes permitting, septic and well setbacks, and how we scope the foundation before we ever open a wall. A kitchen remodel in a 1990s tract home in Folsom typically runs $14,000 to $45,000 depending on layout, cabinet line, and countertop material. A bathroom remodel runs $9,000 to $28,000. Those are written ranges; your written price is the number we both sign before work starts.
Kitchen and Bath Work
We install KraftMaid and Wellborn cabinetry, Cambria and Silestone countertops, and Kohler or Moen fixtures, so the material warranty sits on top of our own. In Folsom’s tract homes, we often see original 1990s vanities and laminate counters that have outlived their hinges and edge banding. A cabinet installation runs $4,000 to $13,000; countertops $2,000 to $6,500; a kitchen island $3,000 to $10,000.
Additions and ADUs on Acreage
Room additions and ADUs are where Folsom acreage gets interesting. A home addition runs $45,000 to $130,000, and an ADU runs $90,000 to $220,000. Those ranges include engineered plans, county permit coordination, and septic or well setback review, because on a Folsom acreage lot, the leach field often dictates where the building can sit before the architect draws the first line.
Licensed General Contractor in Folsom

A Licensed General Contractor in Folsom takes on the coordination that a handyman’s bid never covers: pulling the right permit, scheduling inspections, sequencing trades, and making sure the slab doesn’t heave five years after the concrete cures. On Folsom acreage, we pull Sacramento County permits where required, not city of Folsom permits by mistake, and that draw schedule difference can stall or save a project depending on who’s running the job. We handle it as a standard part of every addition or ADU quote, with the county’s inspection sign-off coordinated before rough-in starts.
Foundation and Soil Work
Folsom’s hot, dry summers and winter frost make expansive clay soil move enough to crack slabs and stucco. Before we add a second story or attach a shop to an existing slab, we bring in a geotech to test for clay lenses and recommend compaction or piering. That allowance goes in the written quote up front, so you don’t get a change order after excavation.
Equipment Access and Hauling
Long gravel driveways and tight turnarounds on Folsom acreage add real daily equipment costs that generic per-square-foot pricing misses. We drive the access path during the estimate so the written number includes what it takes to get materials and machinery to the build site, not a guess.
Trusted Brands We Service in Folsom
We install materials from brands that stand behind their products, because our guarantee sits on top of theirs, not instead of them. On Folsom projects you’ll see James Hardie fiber-cement siding on two-story additions, Cambria or Caesarstone quartz on kitchen counters, and Kohler or Delta fixtures in bathrooms. For exterior hardscape tied to a remodel, we use Unilock and Techo-Bloc pavers, both of which carry manufacturer warranties that run alongside our 365-Day Done Right Promise. We keep common parts stocked at our Sacramento shop, so Folsom jobs aren’t waiting on a backorder from a distributor’s warehouse in another state.

AfterCommon General Contractor Problems We See in Folsom Homes
- Expansive clay under slabs. Folsom’s hot, dry summers bake the clay, and winter frost swells it. We see stucco hairline cracks and slab heaving in Prairie Oaks and Empire Ranch within five to seven years of original build, and we fix the soil condition before we build on top of it.
- Wrong jurisdiction on permits. Folsom acreage often falls under Sacramento County, but homeowners assume city rules apply. Pulling the wrong permit stalls the draw schedule and can trigger a stop-work order mid-project.
- Patio slabs poured without compaction. In the Prairie Oaks and Empire Ranch subdivisions, back patio slabs were frequently poured over uncompacted clay lenses. They heave within five years, and if you’re attaching a shop or addition, that slab needs remediation first.
- Septic and well setbacks ignored on ADU plans. A detached ADU or shop with a bathroom may be pushed 40 feet or more from the house by the existing leach field. If nobody checks the setback before design, the floor plan changes after the permit application is filed, which costs money and months.
Pricing for General Contractor in Folsom, CA
Folsom pricing reflects the acreage realities most city pages ignore: hauling distance, equipment access, soil testing, and county permit coordination all move the number. Here are the written ranges we quote for Folsom work.
| Project Type | Price Range in Folsom |
|---|---|
| ADU Construction | $90,000 – $220,000 |
| Home Addition | $45,000 – $130,000 |
| Kitchen Remodel | $14,000 – $45,000 |
| Bathroom Remodel | $9,000 – $28,000 |
What changes the number? On acreage, septic and well setbacks can force a foundation 40 feet from the house, which lengthens utility runs and grading. Clay soil that tests positive for expansive movement adds compaction or helical piers. Long gravel driveways add hauling and equipment turns. We scope all of it before we quote, so the written number is the number on your invoice. Call (279) 300-1177 for a free estimate.

FAQs About General Contractor in Folsom
Septic and well setbacks usually dictate where the structure can sit before any load-bearing design begins. On a Folsom acreage lot, the leach field must maintain horizontal separation from any dwelling, which can push an ADU or detached shop 40 feet or more from the house. We pull the county’s septic and well records during the estimate so the floor plan fits the parcel, not the other way around. Call (279) 300-1177 and we’ll check your parcel before you pay for plans.
Yes. A shop with plumbing is a dwelling unit under Sacramento County rules, and unpermitted work can cloud your title, block a future sale, and fail a lender’s appraisal if you refinance. We pull the county permit, coordinate the inspection sign-off, and include it in the written price. Call (279) 300-1177 for a quote that covers permitting.
We bring in a geotech to test for clay lenses and compaction, then engineer a solution, which is usually helical piers at the heave-prone corners or over-excavation and recompaction before the new framing goes up. That work is written into the quote so the cost is known up front. Call (279) 300-1177 to schedule a soil evaluation on your lot.
Yes. In Empire Ranch, the original patio slabs were often poured without proper compaction over clay, and if you attach a shop to that slab, the heaving transfers into the new foundation. We remediate the slab first, then build. In Prairie Oaks, our crew scoped a detached ADU on a 1.1-acre lot where the existing septic leach field forced the foundation 40 feet farther from the house than the homeowner planned. We brought in a geotech for clay-lens soil compaction, engineered the slab with helical piers at the heave-prone corner, and coordinated the county’s inspection sign-off on the well setback before the rough-in started. That’s the sequence we follow here. Call (279) 300-1177 for a quote that includes the slab remediation.
Sacramento County inspections are scheduled at specific milestones: foundation after forms and steel, rough-in for framing and mechanicals, then final after the work passes all prior marks. Each inspection is a draw trigger for your lender, so a missed or failed inspection stalls the draw schedule, which stalls the build. We coordinate every county inspection as part of the job, and the written quote includes that coordination. Call (279) 300-1177 for a free estimate on your acreage project.
