General Contractor in Northridge - Licensed & Insured, Written Fixed-Price Quotes

Fast, Reliable General Contractor Across Northridge

If you’re searching for a general contractor in Northridge, CA, you’re likely standing in a home that has already survived more than most houses in this country ever will. The 1994 earthquake split this neighborhood into two worlds: original 1950s – 70s ranch tract homes with unretrofitted cripple walls, and insurance-funded rebuilds from 1994 – 1998 that were sometimes rushed, permits fast-tracked, corners cut at the sill plate. Penhallow Remodeling works both worlds, and we do it with a written price before any work starts and a 365-day guarantee that says if it’s not done right, we make it right. Call us at (936) 259-2607 for a free estimate.

Why Penhallow Remodeling Is Northridge’s Preferred General Contractor Company

Northridge homeowners call us because we answer the phone. A live person picks up 24/7, not a voicemail maze and not a callback window. You get Trevor Nash or someone from our team who knows Northridge, knows the permit tension between city and county jurisdiction, and knows what a 110°F heat spike does to a fresh concrete pour. Our technicians are background-checked and show up in uniform, so you know exactly who’s walking into your home. We work under the Kingswell standard, operating the way it has been since 2004: say the price before the work, show up in the window we gave, leave the place cleaner than we found it, and put the guarantee in writing.

Our General Contractor team has seen the hidden history behind Northridge walls. That’s not a marketing line. It’s what happens when you open up a load-bearing wall on a Devonshire Street acreage property and find OSB nailed to fractured framing from a 1994 fast-track repair. We know what LADBS inspectors will flag, what county jurisdiction covers, and what a rush-job rebuild from 1995 looks like underneath. That local knowledge changes how we scope, how we quote, and how we schedule.

Part of the Kingswell family of companies, each Penhallow location is independently owned and operated. We serve General Contractor in Northridge homeowners directly, with crews working local and scheduling coordinated from the brand’s Los Angeles office.

Hire a General Contractor in Northridge

Hire a General Contractor in Northridge when the job is bigger than a single trade, when permits are required, and when the work touches load-bearing structure, plumbing, electrical, or grading. On Northridge acreage, that almost always means navigating two permitting worlds at once: the City of Los Angeles for the primary dwelling, and county jurisdiction for detached outbuildings, shops, and ADUs with septic and well setbacks. A home addition in Northridge typically runs $45,000 – $130,000. An ADU runs $90,000 – $220,000. A garage conversion lands between $30,000 and $80,000. Those numbers include the reality that pre-quake framing may need structural correction once walls are open.

Written Scope Before Any Demo

We scope the full job before quoting. That means pulling the property’s permit history, checking whether the existing structure is pre- or post-1994, and verifying which jurisdiction actually governs the outbuilding. The written price we hand you is the number on the invoice, and the number on the invoice is the number on day one.

Structural Reality Checks

Northridge homes hide things. Cripple walls re-sheathed with OSB over damaged framing, sill plates that were never replaced, foundation bolting that never happened because the 1994 permit got rushed. We budget for what we can see, and we tell you clearly what happens if we find the things we can’t see.

General Contractor Services in Northridge

General Contractor Services in Northridge cover everything from Kitchen Remodeling - Northridge inside the house to a fully detached ADU at the back of the lot. Kitchen remodels here run $14,000 – $45,000, small kitchens $9,000 – $20,000, and bathrooms $9,000 – $28,000. But the acreage-specific work is where Northridge departs from a typical suburban job. Paver driveways run $7,000 – $18,000, concrete driveways $4,500 – $12,000. Home additions and ADUs require grading and drainage plans, septic and well setback verification, and long material hauls that affect both cost and scheduling.

Detached ADUs and Outbuildings

We build detached ADUs, shops, and outbuildings under county permit jurisdiction when the property crosses the city line. That’s a different approval path, a different inspection schedule, and a different draw schedule than a city-permitted remodel. Get this wrong and you’ll stall mid-project waiting on an inspector who never had jurisdiction in the first place. We verify before we quote.

Grading, Drainage, and Open-Lot Concrete

Open lots in Northridge bake under 108 – 112°F summer heat, and the 30 – 40°F overnight drop stresses stucco, framing, and roofing. Concrete poured in that heat cures too fast unless you use water-reducing admixtures and wet curing covers. We plan pours around the heat, not around convenience.

Trusted Brands We Service in Northridge

We build with materials that carry their own warranties alongside ours. Cambria quartz countertops come with a lifetime warranty from the manufacturer. Kohler and Moen fixtures carry multi-year coverage. James Hardie siding holds up through the Valley’s thermal cycling better than most. For Northridge acreage work, we also work with brands like Dvele when a homeowner wants a precision-manufactured ADU shell. We source these products through local channels so lead times stay short and replacement parts don’t stall a job.

Common General Contractor Problems We See in Northridge Homes

• Post-1994 fast-track structural repairs: Cripple walls re-sheathed with OSB nailed to fractured framing, sill plates never replaced, foundation bolting skipped. A routine remodel permit pull triggers a mandatory structural correction the homeowner didn’t know existed.
• Wrong jurisdiction on outbuildings: Homeowners and even some contractors scope an ADU or detached shop to City of Los Angeles permits when the property falls under county jurisdiction. The draw schedule stalls, inspection sign-off stalls, and the owner pays for it.
• Concrete curing failures in Valley heat: 108 – 112°F summer days with 30 – 40°F overnight swings cause accelerated moisture loss and thermal cracking. Without wet curing covers and proper admixtures, the slab fails long before inspection.
• Long material hauls and equipment access on acreage: Deep lots off Devonshire or west toward Chatsworth often need extended material handling, equipment staging, and sometimes temporary road access. That’s a real cost line item, not a surprise change order.
