And every completed job carries the 90-Day Done Right Promise in writing: if it isn’t done right, Tom comes back and makes it right. One call. Simi Valley homeowners who’ve been burned by phone-quote outfits tend to appreciate that the permit inspector works for them, not for us.
Construction Services We Offer in Simi Valley
Kitchen Remodeling
A Simi Valley kitchen remodel means working with the 1960s and 1970s tract-home footprints that dominate the valley, where load-bearing walls often sit where today’s open-plan layouts need them gone. We carry KraftMaid and Cambria and spec every allowance in writing before demo begins. Learn more about our Kitchen Remodeling in Simi Valley.

Bathroom Remodeling
Bathrooms in older Simi Valley homes frequently hide water damage behind original tile and failing shower pans. We open walls, assess what’s actually there, and provide a written change order if the scope shifts. Learn more about our Bathroom Remodeling in Simi Valley.

Roofing
Simi Valley roofs take punishment from Santa Ana winds that funnel through the valley with recorded speeds among the highest in the LA metro. We install GAF and CertainTeed systems with proper flashing and WUI-rated vent detailing where Chapter 7A applies. Learn more about our Roofing in Simi Valley.

Windows & Doors
Original aluminum-frame windows from the tract-home boom are a weak point in Simi Valley’s summer heat, which is why we offer Windows & Doors - Simi Valley. We install Andersen, Marvin, Simonton, and PGT units sized to the existing openings, with proper flashing for wind-driven rain.

Fence Installation
Simi Valley lot lines run against canyon edges and open space in many hillside neighborhoods. We set posts to handle wind load and soil movement, and we verify property lines before digging.

Driveway & Pavers
Decades of expansive clay and fill soil movement have cracked and heaved plenty of Simi Valley driveways. We use Belgard and Techo-Bloc pavers over properly compacted base, on lots where the original grading may not have settled the way the builder hoped.

Home Additions & ADUs
Adding square footage in Simi Valley means checking the pad first, especially in the hillside tracts north of the 118 where 1970s fill has settled unevenly. We pull permits, handle the grading evaluation, and bring the inspector in before framing closes.

Why Simi Valley’s Climate & Housing Affect Construction
Simi Valley’s rapid suburban build-out between roughly 1963 and 1985 left a dense stock of aging tract homes sitting directly against wildland open space on the valley’s northern and southern ridgelines. That geography puts a large share of the city’s parcels inside California’s designated High or Very High Fire Hazard Severity Zones. What that means for construction here is specific: virtually every significant remodel, addition, or new build in hillside-adjacent neighborhoods must comply with California Building Code Chapter 7A WUI fire-hardening standards. Those rules govern Simi Valley Roofing assemblies, ember-resistant vents, siding materials, and deck construction in ways that don’t apply across the hill in the San Fernando Valley’s LA County jurisdiction.
The valley’s inland bowl also funnels Santa Ana wind events with particular intensity. Summer highs regularly exceed 100°F, stressing exterior finishes, caulking, and wood framing on south- and west-facing elevations faster than coastal-adjacent markets. And on hillside tracts like Wood Ranch and the Knolls, 1970s pad grading placed homes on compacted fill that has since settled unevenly. We make foundation inspections and grading evaluations a standard pre-scope step before any addition or structural remodel on lots that back up to steep canyon grades. The permit inspector works for you, not for me, which is why we like having that step on paper before we quote.
Pricing for Construction in Simi Valley
Construction pricing in Simi Valley is driven by three things: the age of the home, the hillside or flat-lot conditions, and the fire-hardening requirements that apply to the parcel. As a planning reference before we walk your property:
- Bathroom remodel: $22,000 - $48,000, depending on fixtures, waterproofing, and whether we’re repairing hidden water damage
- Kitchen remodel: $45,000 - $95,000, driven by cabinetry, countertops, and structural changes to 1960s-1980s layouts
- Roof replacement: $14,000 - $28,000, influenced by pitch, access, and Chapter 7A WUI material requirements where applicable
- Room addition or ADU: $180,000 - $400,000+, depending on pad conditions, grading, utilities, and fire-hardening scope
Every scope, every allowance, every price change arrives as a written change order before work happens.

FAQs About Construction in Simi Valley
A home addition in Simi Valley typically runs $180,000 to $400,000 or more, depending on pad conditions, foundation work, and whether your parcel falls inside a WUI fire hazard zone requiring Chapter 7A hardening. Homes in Wood Ranch and the Knolls often need grading evaluations before we can price the job accurately. Call (877) 610-1318 for a written estimate.
Yes, in virtually every case. Simi Valley’s building department requires permits for structural, electrical, plumbing, and roof work, and hillside parcels add fire-hardening review. We pull permits and sign off on inspections on every eligible job, because the last contractor most customers used told them permits were optional. The inspector works for you, not for us, and that’s exactly why we want him involved.
If your parcel sits in a High or Very High Fire Hazard Severity Zone, which includes many hillside-adjacent neighborhoods along the valley’s northern and southern ridgelines, the answer is likely yes. That can mean Class A roofing, ember-resistant vents, and specific siding or deck materials. We’ll check your parcel status before you commit to any scope so the quote reflects what the building department will actually require.
Most Bathroom Remodeling in Simi Valley and kitchen projects run six to ten weeks from demo to final inspection, assuming the home’s 1960s-1980s framing doesn’t reveal surprises when we open the walls. If surprising conditions change the scope, you’ll get a written change order before any additional work starts. We don’t do surprise invoices on the back end.
Yes, estimates are free, and we don’t charge a trip fee anywhere inside the county. We also offer a free second opinion on any written estimate you’ve received from another contractor. Call (877) 610-1318 and a live person will schedule the walk-through.

What Simi Valley Customers Say
"Came back a year later to sort a door that had dropped as the frame settled. No charge and no argument about whether it was covered."
- Thaddeus Oyelowo"Addition over the garage matched the original roofline and brickwork so closely that visitors do not realise it was added. He tracked down the closest brick he could find rather than settling."
- Gideon Stroud"The bathroom was finished on the day he said at the start, which nobody had led me to believe was possible."
- Loretta Vanterpool
