Why Mason Remodeling Is Northridge’s Preferred General Contractor Company

Northridge homeowners tend to ask the same three questions before they sign anything: who exactly is showing up, what’s the real price, and what happens if something fails. Those are the right questions. Our crews roll into neighborhoods around CSUN, Dearborn Park, and the Northridge Fashion Center area in marked uniforms, wearing photo ID badges at the door, and you’ll already have their names and photos on your phone before they ring the bell. That’s The Threshold Standard, and it’s how we’ve operated since 2004 as a Threshold Group company.
We’re not here to win a race to the bottom on price. We’re here to scope the job correctly the first time, so the number on your written quote is the number that survives the work. That matters in Northridge, where a 1963 ranch house off Balboa Boulevard and a 1980s two-story near Granada Hills have completely different framing, plumbing, and electrical realities underneath the drywall. Isaac Pruett, our owner, reviews every Northridge project scope personally before it goes to quote.
Every project we complete in Northridge carries a written guarantee with clearly stated coverage terms, including what’s excluded and for how long: 365 days from the completion date. If a repair or installation fails, you get a free second visit at no charge.
Styles & brands we work with







Construction Company in Northridge
A construction company in Northridge handles the structural work: room additions, garage conversions, ADU construction, and any project that requires permits, engineered drawings, and inspections. This is the part where experience in Northridge’s specific housing stock matters most. Much of the single-family inventory between Nordhoff Street and Lassen Street was built in the 1950s and 1960s tract boom, which means original 2×4 framing, cast-iron waste lines, and 100-amp electrical panels hiding behind drywall. A construction company that prices off the visible surface will miss those. We don’t.
Room Additions and ADUs
Room additions in Northridge typically run $45,000 – $130,000 depending on square footage, foundation type, and whether the existing panel has the capacity to carry the new load. ADU construction runs $90,000 – $220,000, and because Northridge sits in a high-fire-severity zone along the Santa Monica Mountains foothills, exterior scopes often trigger brush-clearance and roof-class requirements that inland flatland cities don’t face. We pull all permits and coordinate inspections so the sign-off is clean.
Garage Conversions
Converting a detached garage in Northridge runs $30,000 – $80,000. Common complications include raising the floor to meet living-space code, running new sewer lines from the original slab, and upgrading the electrical service. We scope these line-by-line before quoting, so you’re not surprised at rough-in.
Remodeling Contractor in Northridge

A remodeling contractor in Northridge handles kitchens, bathrooms, and whole-home interior work that often requires demolition, framing repairs, and finish carpentry. Northridge’s 1950s – 60s ranch homes are full of load-bearing walls that look innocent until you open them. On a 1962 ranch house off Balboa Boulevard near Dearborn Street, our crew opened a galley kitchen wall only to find a load-bearing header over the old pass-through and a subfloor that had swelled from a decades-old slow leak under the sink. We pulled the right permits, added a change order for the header and subfloor repair, and finished with KraftMaid cabinets, a Cambria counter, and a Moen faucet. The homeowner got the open plan they wanted, and the inspection sign-off cleared on the first pass.
Kitchen Remodels
Kitchen remodels in Northridge run $14,000 – $45,000 for a full gut and rebuild, with smaller kitchens starting around $9,000 – $20,000. Cabinet installation alone is $4,000 – $13,000, and countertops run $2,000 – $6,500. The big cost drivers are layout changes, plumbing relocation, and any structural work behind the walls.
Bathroom Remodels
Bathroom remodels run $9,000 – $28,000, with small baths starting at $5,000 – $12,000. Walk-in shower installations run $4,500 – $12,000. If your home still has original galvanized supply lines, budget to replace them while the walls are open. Leaving them in saves money now and costs more later.
Trusted Brands We Service in Northridge
We install specification-grade materials from brands vetted for long-term performance, and we stock common replacement parts locally for Northridge customers. That means faster turnaround on punch-list fixes and warranty follow-ups without waiting on shipped parts. For kitchens, we work with KraftMaid and Wellborn cabinetry, Cambria and Silestone surfaces, and Kohler, Moen, and Grohe fixtures. For exterior scopes, we specify GAF and Owens Corning roofing systems. If you’re considering a prefab ADU, we’ve worked with Abodu and Cover and can coordinate as your General Contractor team on the site work, foundation, and utility connections.

AfterCommon General Contractor Problems We See in Northridge Homes
- 1950s galvanized supply lines: These corrode from the inside and often fail during a remodel, once the water is shut off and turned back on. If your home hasn’t had a re-pipe, budget for it.
- Undersized 100-amp electrical panels: Adding a kitchen island with outlets, a second bath, or an ADU often requires a panel upgrade. We flag this during scoping, not mid-job.
- Load-bearing walls in ranch layouts: Many Northridge galley kitchens have a structural header over the pass-through. Opening that wall without proper support is dangerous and will fail inspection.
- High-fire-zone exterior rules: Repairs and additions near the Santa Monica Mountains foothills trigger brush-clearance and fire-rated roof or siding requirements that add cost and review time.

FAQs About General Contractor in Northridge
Yes, any remodel that moves plumbing, alters framing, or changes the electrical layout requires a permit in Northridge, no exceptions. Unpermitted work resurfaces at resale and can block a sale entirely. We pull all permits and coordinate inspections. Call (803) 680-2547 if you’re unsure whether your project needs one.
Because the original quote was built on a verbal walkthrough, not a written scope of work. In Northridge’s 1950s – 60s tract homes, opening a wall often reveals galvanized supply lines, load-bearing headers, or subfloor rot that couldn’t be seen before demolition. Our written quotes include a line-by-line scope and we flag likely structural risk areas before you sign, so the price doesn’t move unless you approve a change order in writing.
A bathroom remodel in Northridge typically runs 3 – 5 weeks. A kitchen remodel runs 6 – 10 weeks depending on layout changes, structural work, and inspection scheduling. Permit review times in Northridge can add 2 – 4 weeks before demolition starts. We give you a written schedule with the quote, and we stick to it unless the building department or a structural surprise intervenes.
Yes, and it’s common in Northridge where detached garages are standard on the original tract lots. Garage conversions run $30,000 – $80,000 depending on whether you need a new foundation, sewer line extensions, or a panel upgrade. Full ADU construction runs $90,000 – $220,000. We handle the site work, permits, and inspections for both.
We install KraftMaid and Wellborn cabinetry, Cambria, Silestone, and Caesarstone countertops, and Kohler, Moen, Toto, and Grohe fixtures.
