We’re Penhallow Remodeling, and we work across Whittier every week, from the Craftsman streets of Uptown to the sloped lots in the Whittier Hills and East Whittier. Trevor Nash leads our team, and the promise we make is simple: a written price before we start, a real arrival window, and a 365-day guarantee that if it’s not done right, we make it right.

Why Penhallow Remodeling Is Whittier’s Preferred General Contractor Company
Whittier homeowners call us because we answer the phone. A live person picks up 24/7, no voicemail maze, no “we’ll get back to you within 48 hours.” When you’re standing in a kitchen with a wall opened up and a surprise behind it, that matters. Our technicians are background-checked and arrive in uniform, so the person at your door is the person we described on the phone.
We’ve built our reputation in Whittier by handling the jobs other contractors price wrong. Uptown’s 1920s and 1930s brick commercial stock, the hillside homes with aging retaining walls, the mid-century ranches in East Whittier with knob-and-tube wiring still live behind the drywall. Our General Contractor in Whittier team writes allowances into the contract for exactly these conditions, so a discovery behind a wall doesn’t become a fight over the invoice. That’s what the Kingswell standard means: say the price before the work. Show up in the window we gave. Leave the place cleaner than we found it.
Construction Company in Whittier
Construction Company work in Whittier means something different than it does two cities west. The Whittier Fault runs directly through the hillside neighborhoods, placing large portions of upper Whittier inside California Alquist-Priolo Earthquake Fault Zones. Any room addition or structural project on those lots typically requires a fault-setback study and a peer-reviewed geotechnical report before plan check will even look at your drawings. A home addition in Whittier runs $45,000 – $130,000 depending on scope, and the geotechnical layer alone can add thousands and several weeks to the front end. We plan for it from day one.
Hillside Foundation Work
Whittier’s expansive adobe and clay soils swell and shrink through wet and dry cycles. We see foundation heave, slab cracking, and retaining wall rotation on hillside lots that flat neighboring cities never deal with. Before we frame an addition, we check what the existing foundation is actually doing.
Seismic Retrofit and URM Compliance
When a permit gets pulled on older masonry buildings near Greenleaf Avenue, LA County’s mandatory URM retrofit ordinance can trigger structural work that doubles the project scope. We handle the anchoring, shear-wall design, and the paperwork so the retrofit gets done once and passes inspection.
Remodeling Contractor in Whittier
Remodeling Contractor work in Whittier often starts with a simple kitchen or bathroom update and turns into a structural conversation once the walls come open. The 1987 Whittier Narrows earthquake damaged a lot of the city’s older masonry, and decades of deferred maintenance sit behind those plaster walls. A Kitchen Remodeling - Whittier project runs $14,000 – $45,000, with small kitchens starting around $9,000 – $20,000. Bathroom remodels run $9,000 – $28,000, and small baths start at $5,000 – $12,000.
What drives the number is rarely the finish you pick. It’s what we find when we open the wall: outdated wiring, undersized headers, failed waterproofing, and code upgrades the permit triggers. We handle it with a written allowance in the contract, and any change order is priced and approved before we touch it.
Kitchen Remodels in Whittier Homes
We opened a wall in a 1928 Craftsman on Greenleaf Avenue for a kitchen island rough-in and found knob-and-tube wiring and a header that wasn’t load-bearing as drawn. The inspection sign-off triggered a URM assessment because the adjacent brick facade shared a wall. We priced the shear-wall work, wrote the change order, and got approval before anything moved forward. The kitchen finished with KraftMaid cabinets and a Cambria island top on the revised schedule.
Bathroom Remodels and Shower Work
Bathrooms in Whittier’s older homes often sit on mud-set floors that are cracked and out of level. We replace the substrate, re-waterproof, and install fixtures from Kohler and Moen. The work carries our 365-Day Done Right Promise, and the materials carry their own manufacturer warranties. Two layers of protection, both in writing.
Trusted Brands We Service in Whittier
We install and service cabinetry from KraftMaid and Wellborn, countertops from Cambria, Silestone, and Caesarstone, and fixtures from Kohler, Moen, and Delta. We also work with prefab and panelized building systems from Abodu, Cover, and Dvele where they fit a Whittier lot, particularly for ADU and addition work where the hillside soils favor engineered panels over stick framing. We stock common replacement parts locally and coordinate directly with manufacturers on warranty claims, so a Kohler cartridge or a KraftMaid hinge doesn’t leave your kitchen down for two weeks.
Common General Contractor Problems We See in Whittier Homes
- Knob-and-tube wiring behind 1920s – 1940s walls in Uptown and East Whittier. It’s not always a dealbreaker, but it has to be evaluated before rough-in. We include wiring assessment in every remodel inspection.
- Unreinforced brick on Greenleaf Avenue and the Uptown commercial core. A permit for tenant improvements or an addition can trigger LA County’s mandatory URM retrofit ordinance. That structural scope can double a project, and lowball bids never accounted for it.
- Expansive adobe and clay soils on hillside lots causing slab cracks and retaining wall rotation. We see this in the Whittier Hills every winter after the rains. The fix usually requires a structural engineer, not just a patch.
- Failed waterproofing and dry rot around windows and decks on mid-century hillside homes. Whittier gets marginally more rain at the foot of the Puente Hills than the LA basin floor, and older flashing details were never designed for it.

FAQs About General Contractor in Whittier
Yes, if your property sits inside one of the Alquist-Priolo Earthquake Fault Zones in the Whittier Hills, a fault-setback study and a peer-reviewed geotechnical report are typically required before plan check approves a room addition or structural remodel. The report tells us how close the fault traces run to your lot and what foundation design the soils can support. We coordinate the geotech work and build it into the written price so you’re not surprised mid-permit. Call (936) 259-2607 and we’ll check your parcel against the fault zone maps.
LA County’s mandatory URM retrofit ordinance likely kicks in the moment the permit is pulled, which means seismic anchoring, shear-wall reinforcement, and possibly roof-to-wall connections before any interior work gets finaled. The structural scope can double a project that a flatland contractor priced as a simple remodel. We handle the engineering, the anchoring, and the inspection paperwork as part of the written contract, and we price the retrofit before we start so the permit set doesn’t fall apart mid-job.
We inspect first, then we write allowances into the contract for the conditions most likely to turn up in Whittier’s housing stock: knob-and-tube wiring, undersized headers, failed waterproofing, and URM triggers in the brick buildings around Uptown. Any change order gets priced in writing and approved by you before we touch the permit set. The number on your original contract is the number on the invoice unless you approve a change. No verbal estimate creep, no “we found something” phone call with a blank number.
The expansive adobe and clay soils. When those soils cycle through wet and dry seasons, they heave foundations, rotate retaining walls, and crack slabs. A project that starts as a kitchen remodel can turn into foundation repair once we open the floor and see what’s underneath. We budget for soil-related discoveries on every hillside job and write the allowance into the contract, so a cracked slab doesn’t become a change-order negotiation at the worst possible moment.
Yes. Kitchen and bathroom remodels in Whittier routinely require permits, and permits on older Whittier homes trigger structural reviews, electrical inspections, and sometimes URM retrofits that require a licensed contractor to sign off. A handyman can hang cabinets; they can’t pull the permit, manage the geotechnical report, or sign the structural change order. We run the whole permit process and the job site. Call (936) 259-2607 for a free estimate and we’ll walk you through what your specific Whittier property needs.
