AfterConstruction in Northridge, CA
Kitchen remodeling in Northridge runs $14,000-$45,000 across most homes, with the biggest variable being what’s hiding inside the wall. The city’s 1950s-1970s ranch stock and post-earthquake patch jobs mean a simple cabinet swap can turn into structural re-shearing once the drywall comes down. Rowan Construction Group writes the full price on paper before anyone picks up a tool, so that discovery never becomes a surprise line item. Call (470) 298-9650 and we’ll put the number in writing.
Why Northridge Homes Are Different
Northridge is the namesake of the January 17, 1994 magnitude 6.7 earthquake, and that event still shapes every interior wall, roofline, and foundation in the city. Homes built between 1955 and 1975 were engineered for a seismic code that predates the Northridge lessons by two decades. After 1994, crews swarmed through patchwork repairs: plywood shear panels, added hold-downs, sistered framing. Much of that work happened under emergency orders and never made it onto a permit record. So when we open a wall on Reseda Boulevard or Lassen Street for a kitchen or bathroom remodel, we often find a sandwich of original 1960s framing, 1994 repairs, and 1995-1997 reconstruction, all bearing load in ways the current building code doesn’t recognize. The valley location matters too. Northridge regularly hits 100°F in summer, so we schedule concrete pours for early morning and use wet-curing methods that account for how fast moisture leaves fresh mud in valley air. Those dry Santa Ana cycles also pull water out of fresh stucco and grout faster than coastal jobs 20 miles south, which changes how we set tile and cure masonry. Any contractor who doesn’t adjust for this gets hairline cracks, and in Northridge, cracks make buyers nervous for good reason.
Our Main Northridge Services
Two services get the most calls from Northridge homeowners because both sit at the intersection of curb appeal, HOA restrictions, and the valley’s hard sun. Each has its own dedicated page with full pricing.
Fence Installation in Northridge
Northridge fence jobs usually mean replacing 1960s-era redwood or chain-link that’s warped from decades of valley heat and Santa Ana wind. Many HOAs in the Northridge area have specific height, material, and setback rules, and we pull those requirements before we quote so the written price matches what the HOA will actually approve. We install vinyl, aluminum, and wood fences and always set posts in concrete below the shrink-swell soil line. Fence Installation in Northridge has the full local pricing breakdown.
Driveway & Pavers in Northridge
Driveway work in Northridge starts with what the 1994 quake did to the slab. Many original driveways cracked during the event, got a cosmetic patch, and have been slowly separating ever since. We remove and replace or install paver driveways and patios, using a compacted base that tolerates the valley’s thermal expansion cycles better than a monolithic slab. The heat also means we pour concrete before 9 a.m. in summer to avoid rapid-cure cracking. Driveway & Pavers in Northridge covers paver and concrete pricing.

BeforeAfterKitchen Remodeling in Northridge
Kitchen remodeling in Northridge typically runs $14,000-$45,000, and the range is wide because the 1960s and 70s ranch homes here conceal what we call earthquake patches: plywood shear panels and added framing that never got a permit. When we open the kitchen wall on a home near Cal State Northridge or along Devonshire Street, hidden structural work sometimes has to be corrected before cabinetry goes in. That’s why our Kitchen Remodeling process starts with a written price based on a physical inspection, not a phone estimate. We use KraftMaid and Wellborn cabinets and Cambria and Caesarstone countertops, so the line items reflect real material numbers you can verify.
Full Kitchen Remodeling
Signs you need it
Your floor plan blocks flow between sink, stove, and refrigerator, or the existing layout belongs to an era before dishwashers and microwaves were assumed.
What it costs in Northridge
Full kitchen remodeling in Northridge runs $14,000-$45,000 depending on cabinet grade, countertop material, and how much hidden seismic patchwork we have to correct.
How we do it
We measure, inspect inside the walls for 1994-era patchwork, produce a written scope and fixed price, then build in this order: demo, structural correction, rough plumbing and electrical, drywall, cabinets, counters, tile, finish.
Cabinets & Countertops
Signs you need it
Doors no longer align, hinges pull free from particleboard, or the countertop is delaminating along the sink cutout.
What it costs in Northridge
Cabinet installation alone is $4,000-$13,000; countertops run $2,000-$6,500 in Northridge.
How we do it
We set cabinets on shimmed, leveled bases before fastening to studs, and we install counters over a verified-flat substrate so the slab never bridges void and cracks.
What Kitchen Remodeling Costs in Northridge
| Item | Typical range in Northridge |
|---|---|
| Small kitchen remodel | $9,000-$20,000 |
| Backsplash installation | $800-$2,500 |
| Kitchen island installation | $3,000-$10,000 |
Will my kitchen remodel uncover earthquake damage in Northridge?
Possibly. Homes built before 1994 often have undocumented shear panels and added framing inside kitchen walls. We inspect as part of the written quote so structural work is in the price before we start.
Can I get a fixed kitchen remodel price in Northridge before work starts?
Yes. We physically inspect the space, identify structural corrections and material selections, then write a flat price with a written scope. Call (470) 298-9650 to schedule the free estimate.
Bathroom Remodeling in Northridge
Bathroom remodeling in Northridge runs $9,000-$28,000, with small bathrooms starting around $5,000. The post-WWII ranch homes here were built with cast-iron drain stacks that are now 50-70 years old, and many still carry earthquake cracks in the shower pans or tile mud beds that were never fixed. Our Bathroom Remodeling crew opens the wall, checks the drain stack and the condition of the framing behind the tile, and puts what we find in the written price before demolition starts.
Walk-In Showers & Shower Remodeling
Signs you need it
Grout is cracking or missing at the floor line, the pan liner is 25-plus years old, or moisture is reading through the drywall on the room behind the shower.
What it costs in Northridge
Walk-in shower installation runs $4,500-$12,000 in Northridge; a full shower replacement is $3,000-$8,500.
How we do it
We pull the old substrate to the studs, inspect for earthquake-cracked framing, install a bonded waterproof membrane over solid backing, and slope the mud bed before tiling.
Tub-to-Shower Conversion
Signs you need it
The tub is unused, the step-over height is a fall hazard, or the tub’s cast-iron underside has rusted through from decades of valley hard water.
What it costs in Northridge
Tub-to-shower conversion runs $3,500-$10,000 in Northridge.
How we do it
We remove the tub, re-grade the waste line to a shower drain, install a waterproof membrane and solid substrate, and set the new base and tile.
What Bathroom Remodeling Costs in Northridge
| Item | Typical range in Northridge |
|---|---|
| Small bathroom remodel | $5,000-$12,000 |
| Bathroom vanity installation | $800-$3,000 |
| Full bathroom remodel | $9,000-$28,000 |
Will a bathroom remodel in Northridge require a permit?
Most full remodels do when we relocate plumbing or open walls. We pull permits and schedule inspections as part of the written scope, not as a change order later. Call (470) 298-9650 with questions.
How long does a Northridge bathroom remodel take?
Most run two to four weeks depending on the level of existing damage and whether tile needs wet-curing time that accounts for valley heat. The schedule is written into the quote.
Roofing in Northridge
Roof replacement in Northridge runs $8,000-$20,000, and roof repair falls between $400 and $1,800. The valley’s 110°F summer afternoons bake asphalt shingles until they become brittle, while Santa Ana wind cycles lift and curl edges on the same homes that got quick re-nailing jobs after the 1994 quake. Our Roofing crews inspect the decking, count shingle layers, and identify hidden earthquake-induced rafter cracks before we quote, because the Northridge area still has thousands of roofs carrying 30-year-old patch materials.
Roof Replacement & Installation
Signs you need it
Shingles are curling, granule loss is visible at downspout exits, or the original 1960s roof decking is failing around old nails popped loose by quake movement.
What it costs in Northridge
Roof replacement runs $8,000-$20,000 in Northridge; full metal roof installation starts at $15,000 and reaches $40,000.
How we do it
We tear down to decking, inspect for cracked rafters and dry-rot, replace damaged sections, install a synthetic underlayment, and set GAF or Owens Corning shingles to manufacturer wind and heat specs.
Roof Repair
Signs you need it
Water stains appear on ceilings after storms, ridge caps are missing, or you see lifted shingle edges after a Santa Ana wind event.
What it costs in Northridge
Roof repair in Northridge runs $400-$1,800; tile roof repair is $600-$2,500.
How we do it
We locate the leak source, map the damaged area, replace the failed material, and photograph the repair before and after for the documented record we give you on every visit.
What Roofing Costs in Northridge
| Item | Typical range in Northridge |
|---|---|
| Roof replacement | $8,000-$20,000 |
| Roof repair | $400-$1,800 |
| Tile roof repair | $600-$2,500 |
Does Northridge heat change what roofing material I should choose?
Yes. Flat-roof and low-slope structures take a beating in 100°F-plus summers, and darker asphalt shingles absorb more heat. We spec lighter-tone GAF or Owens Corning shingle lines and proper attic ventilation for valley conditions. Call (470) 298-9650 for a free roof inspection.
Do you fix roofs damaged by the 1994 Northridge earthquake?
We repair and replace roofs on homes with quake-era rafter cracks and popped nails. The inspection documents what we find so you have a record, not a verbal claim.
Windows & Doors in Northridge
Window replacement in Northridge runs $4,500-$15,000, and impact windows start at $8,000. The ranch homes here still have original single-pane aluminum frames from the 1960s that flex in valley heat and rattle during Santa Ana winds, and many were never upgraded after the 1994 quake. Our Windows & Doors team measures every opening, checks the rough framing for quake-induced racking, and writes the price for what we find, not a per-window guess.
Window Replacement
Signs you need it
Frames no longer seal, glass sweat forms between panes, or the original aluminum tracks have warped from repeated 100°F expansion cycles.
What it costs in Northridge
Window replacement in Northridge runs $4,500-$15,000 depending on count, glazing, and whether impact-rated glass is required.
How we do it
We remove the old unit, check the sill and rough opening for rot and quake racking, correct any issues, then install with new flashing and insulation to cut valley heat gain.
Impact Windows & Doors
Signs you need it
You want opening protection during earthquake aftershock and wind events, or your insurance carrier requires impact-rated fenestration for wildfire-adjacent or high-wind zones.
What it costs in Northridge
Impact window installation runs $8,000-$25,000 in Northridge.
How we do it
We spec laminated glass units rated for the exposure, install them into structurally verified openings, and photograph the final assembly for your record.
What Windows & Doors Costs in Northridge
| Item | Typical range in Northridge |
|---|---|
| Window replacement | $4,500-$15,000 |
| Impact window installation | $8,000-$25,000 |
| Door installation (typical) | $1,500-$6,000 |
Do Northridge homes need impact windows?
Not for code compliance, but many homeowners choose them for the seismic and wind event resilience. We quote standard and impact lines so you can compare the written numbers side by side. Estimates are free at (470) 298-9650.
Will new windows lower cooling bills in the Northridge summers?
Usually, yes. Replacing single-pane aluminum with dual-pane low-E units cuts direct solar heat gain, which matters when outside temperatures sit above 100°F. We can show you the glazing specs before you decide.
Home Additions & ADU in Northridge
Home additions in Northridge run $45,000-$130,000, and ADU construction starts around $90,000. The city’s 1950s-70s single-story ranches are prime candidates for attached additions and rear-yard ADUs because lots are deep enough to build while keeping the existing house habitable. Our Home Additions & ADU process starts by checking for the unpermitted 1994-era patchwork that changes foundation and shear requirements, then we quote the written scope that includes the city’s plan-check fees and school district impact fees.
Garage Conversion ADU
Signs you need it
The garage is a storage dead zone, the slab passes inspection, and the city zoning already permits an attached ADU on your lot.
What it costs in Northridge
Garage conversion to ADU runs $30,000-$80,000 in Northridge.
How we do it
We assess the existing slab and framing, design the conversion to current seismic and energy codes, pull permits, and build the unit with the same documented photo record as every other Rowan job.
New Detached ADU
Signs you need it
You have rear-yard space, need rental income or a place for family, and want separation from the main house.
What it costs in Northridge
New detached ADU construction runs $90,000-$220,000 in Northridge.
How we do it
We survey, design, permit, and build from foundation to finish, including the utility connections, drainage, and the required new panel if the existing service can’t carry the additional load.
What Home Additions & ADU Costs in Northridge
| Item | Typical range in Northridge |
|---|---|
| Home addition | $45,000-$130,000 |
| ADU construction | $90,000-$220,000 |
| Garage conversion | $30,000-$80,000 |
Does Northridge zoning allow ADUs on most lots?
Most residential lots in Northridge fall under state ADU rules that preempt local restrictions on one or two units, but setback and size limits vary. We confirm your lot’s allowances before design begins. Call (470) 298-9650.
How long does an ADU take to build in Northridge?
Typically five to nine months depending on plan-check turnaround and the amount of site work required. The schedule milestones go into the written scope, and changes only proceed with a signed change order.
