Fast, Reliable General Contractor Across Loomis
Most general contractor work in Loomis isn’t a simple swap of cabinets. The town’s semi-rural, foothill location means large lots, septic systems, wells, aging ranch houses, and additions that need real site work. Homeowners here need a contractor who understands Placer County permitting, not just who can swing a hammer. Our crews serve Loomis from our Sacramento office, but the work is local: we know the parcels off Horseshoe Bar Road, the drainage patterns on the open lots, and what an original 1968 septic system means for your planned addition. We give you a written price before any work starts, and that number holds. Call (279) 300-1177 to schedule a free estimate.
Why Penhallow Remodeling Sacramento Is Loomis’s Preferred General Contractor Company

Homeowners in Loomis call us because the number we write down on day one is the number on the final invoice. No verbal ballpark, no change order creep. That matters a lot when you’re budgeting a $45,000 addition or a $90,000 ADU on acreage. You don’t want surprises, and neither do we: our entire Kingswell standard is built around the written price, the arrival window, and a clean job site.
Our reviews from Loomis customers consistently mention two things: we answer the phone, and we show up when we say we will. A live person answers 24/7, so when you call at 7 a.m. on a Tuesday to ask about a permit question, you get a real person, not a voicemail maze. Every technician who walks onto your Loomis property is background-checked and in uniform, so you know exactly who you’re letting in.
Trevor Nash has built this company around one principle: explain the trade word, then quote the honest price. Cement board substrate, the moisture-resistant layer behind your tile, is not a phrase we’d throw at you and walk away. We explain what it is, why it matters, and what it costs. That’s the kind of contractor Loomis homeowners keep recommending to their neighbors.
Styles & brands we work with






Construction Company in Loomis
A construction company in Loomis does work that suburban contractors in Roseville rarely touch: additions that trigger septic evaluations, detached ADUs with well setbacks, outbuildings and shops on acreage, and grading that keeps drainage off a neighbor’s orchard. We handle the county permits, the site planning, and the building itself, so instead of juggling three separate contractors you get one written quote and one team. Home additions in Loomis run $45,000 – $130,000, and garage conversions typically land between $30,000 – $80,000 depending on the condition of the slab, the framing, and whether the existing septic system can absorb another bathroom.
Septic and Well Coordination
Adding square footage to an older Loomis home often triggers a septic system expansion or replacement. Placer County requires a septic evaluation before issuing most addition permits, and what the evaluator finds can change your budget by $20,000 to $40,000. We scope this before quoting, so the written price you get reflects reality, not hope.
Outbuildings, Shops, and Detached ADUs
A detached ADU in Loomis means checking the well and septic setbacks on the actual parcel. Many lots here have both on the same side of the house, which leaves less buildable area than the plat map suggests. We verify all of this before we hand you a number. ADU construction in Loomis runs $90,000 – $220,000, including the site work, foundation, and utility coordination.
Remodeling Contractor in Loomis

A remodeling contractor in Loomis handles the interior work that makes an aging ranch house livable again: kitchens, bathrooms, whole-home updates. But because so many Loomis homes were built between the 1960s and 1990s, we’re often working around old framing, original plumbing, and sometimes the same septic system that came with the house. That’s not a problem; it’s just part of the quote. Kitchen remodels in Loomis run $14,000 – $45,000, and a bathroom remodel lands between $9,000 – $28,000 depending on whether you’re moving walls or keeping the existing footprint.
Kitchen Remodels with Real Numbers
We tell you up front that cabinets from KraftMaid or Wellborn will push the price one direction, while Cambria or Silestone countertops will move it another. A small kitchen remodel in Loomis can run $9,000 – $20,000, and a full cabinet installation alone sits between $4,000 – $13,000. You choose the material; we show you the line item before you commit.
Bathroom Upgrades Without Guesswork
A walk-in shower installation in Loomis runs $4,500 – $12,000, and a tub-to-shower conversion typically lands between $3,500 – $10,000. We install Kohler and Moen fixtures, and every job comes with our 365-Day Done Right Promise in writing. If the work fails inside that year, we come back and fix it at no charge.
Trusted Brands We Service in Loomis
We source materials from recognized trade brands because they support the guarantee we put in writing. Cambria quartz carries its own lifetime warranty alongside ours. James Hardie siding holds up through Loomis summers that top 100°F for weeks at a time. For outdoor work, we install Unilock and Techo-Bloc pavers, which handle the region’s heavy winter rain and long dry heat better than poured concrete alone. We keep local stock familiar to Loomis customers and coordinate deliveries to long gravel driveways off Horseshoe Bar Road without blowing the schedule.

AfterCommon General Contractor Problems We See in Loomis Homes
- Septic systems sized for a smaller house: Many original leach fields off Horseshoe Bar Road were sized for the original 1960s – 1990s footprint. Adding a bedroom or bathroom can overload them, which Placer County flags immediately.
- Well and septic setbacks that shrink the buildable area: Both systems often sit on the same side of the house on Loomis parcels, leaving less room for a detached shop or ADU than the plat map shows.
- Long gravel driveways and material haul timing: A crew without a plan for staged deliveries and concrete pump trucks can lose a full day getting materials to the back of a 2-acre lot.
- Drainage that crosses property lines: Open-lot grading in Loomis can send water toward a neighbor’s pasture or orchard. We grade to keep water on your parcel, and we document it in the permit drawings.

FAQs About General Contractor in Loomis
You might. Placer County requires a septic evaluation before issuing most addition permits in Loomis, and many original leach fields are sized for the house as it was built in the 1960s, 1970s, or 1980s. If the system lacks capacity, the addition triggers an expansion or replacement, which can add $20,000 to $40,000 to the job. Call (279) 300-1177 to have your parcel checked before you commit to a plan.
Placer County enforces a 100-foot setback between a well and any new septic tank or leach field. On Loomis parcels where the well and septic both sit on the same side of the house, that can eliminate a large portion of the lot from consideration. We verify the setbacks on your actual parcel before quoting, so the price reflects what’s buildable, not what the plat map suggests.
Yes. We pull all Placer County permits, coordinate the required septic evaluation, schedule inspections, and keep the paperwork moving. You don’t need to become a permit expert; that’s part of the job. Estimate is free, and the written price includes the permit scope. Call the office at (279) 300-1177 with any questions.
Yes, and we’ll address it in the grading plan before the foundation is poured. Placer County will not sign off on a project that directs water onto an adjacent property. We regrade the pad to keep drainage on your parcel, and we include that cost in the written quote. For an exact figure on your lot, schedule a free estimate with our team.
Most detached ADUs in that size range take 6 to 9 months from permit application to final inspection. Septic evaluation, well setback verification, and county review typically add 6 to 10 weeks at the front end on Loomis parcels. Call (279) 300-1177 and we’ll give you a written timeline along with the written price.
