Fast, Reliable General Contractor Across Irvine
Finding a General Contractor who understands Irvine’s village-by-village rules is the difference between a smooth remodel and a stalled permit. We’re Toolbox Contractors, led by Norm Castellano, and we’ve built our entire Irvine workflow around the design-review boards, HOA standards, and builder-grade housing stock that define this city. From Woodbridge townhomes to Great Park single-family tracts, we know where approvals get hung up and how to keep your project moving. Call (855) 382-3257 for a free estimate on any scope, inside or out.
Why Toolbox Contractors Is Irvine’s Preferred General Contractor Company
Irvine homeowners don’t need a contractor who figures out the rules as they go. They need someone who already knows them. Our work across the city’s villages, from Northwood to Turtle Rock, means we’ve sat in enough pre-construction meetings with HOA boards to predict what gets flagged. That translated into faster architectural approvals and fewer redesign loops for our Irvine customers, which matters when you’re paying carrying costs on a project.
Our reputation in Irvine is built on the full-scope model. One contract covers your kitchen cabinets, your roof, your windows, and your hardscape. No coordinating five different specialists. No overlapping warranties that point fingers. Norm Castellano runs the crew with a simple rule: if it’s on the permit, we own it. Irvine homeowners tell us the single point of accountability is what sold them, especially on projects spanning interior and exterior work.

Hire a General Contractor in Irvine
Hire a General Contractor in Irvine when your project touches more than one trade, and you’ll avoid the chaos of juggling electricians, plumbers, framers, and inspectors yourself. The most common trigger is a kitchen or bathroom gut, but Irvine’s housing stock creates a second driver: exterior work that needs HOA sign-off before the city will even look at your permit. A kitchen remodel in a 1980s Woodbridge tract runs $14,000 to $45,000. A bathroom remodel lands between $9,000 and $28,000. Both ranges assume you’re working with a contractor who handles the full scope, not just one piece.
Full-Scope Remodeling
When a homeowner wants new KraftMaid cabinets, a Cambria countertop, and a roof replacement on the same property, they need one contractor who carries the whole permit. We install and warranty every phase, which means the cabinet installer and the roofer answer to the same lead. That’s how a project in a Portola Springs home went from HOA approval to final inspection without a single coordinator call to a third party.
ADU and Prefab Builds
Irvine’s ADU boom is real, and we’re ahead of it. Through partnerships with Abodu, Dvele, and Plant Prefab, we can deliver a permitted accessory dwelling unit faster than a traditional stick-built addition. ADU construction in Irvine runs $90,000 to $220,000 depending on size, site prep, and whether you go prefab or custom. In many Irvine villages, the design-review step applies to ADUs too, so plan for that approval window.
General Contractor Services in Irvine
General Contractor Services in Irvine span interior and exterior scopes, often on the same project. A homeowner replacing builder-grade cabinets in a Northwood kitchen might extend the job to a window swap and a paver patio, and that’s exactly the kind of bundled work we’re built for. The price ranges below reflect what we see across Irvine’s villages:
| Service | Typical Irvine Range |
|---|---|
| Kitchen Remodel | $14,000 – $45,000 |
| Bathroom Remodel | $9,000 – $28,000 |
| Cabinet Installation | $4,000 – $13,000 |
| Countertop Installation | $2,000 – $6,500 |
| Roof Replacement | $8,000 – $20,000 |
| Window Replacement | $4,500 – $15,000 |
Interior Upgrades
Most Irvine remodels start with the kitchen and bathrooms. Builder-grade cabinets in 1990s tracts are the first thing to go, replaced with Wellborn or KraftMaid lines that fit non-standard framing. Walk-in shower installations run $4,500 to $12,000 in Irvine, and tub-to-shower conversions land between $3,500 and $10,000. We install Kohler and Moen fixtures, and we stock the Schluter waterproofing systems that pass Irvine’s code on the first try.

Exterior Upgrades
Exterior work in Irvine means planning for design review. Roof replacements with GAF, CertainTeed, or Owens Corning systems run $8,000 to $20,000, and tile roof repairs on the Spanish-revival homes in Turtle Rock fall between $600 and $2,500. Window replacement, especially impact-rated PGT or CGI units for foothill villages, ranges $4,500 to $15,000. We handle the architectural sign-off before we pull the permit, because in Irvine that’s the sequence that works.

Trusted Brands We Service in Irvine
We service and install the brands Irvine homeowners actually research. That includes GAF and CertainTeed roofing systems with installer credentialing that backs the warranty, plus Boral and Tamko options for specific roof profiles. On the window side, PGT and CGI impact-rated lines come up often in the foothill-adjacent villages where ember resistance matters. We keep strong local stock for Irvine jobs, which means fewer waiting days on backordered trim or fasteners when your project is already underway.

AfterCommon General Contractor Problems We See in Irvine Homes
- Skipping HOA architectural approval before pulling permits. In Irvine, the village design-review board can reject your paint color or window style before the city accepts your application. We submit architectural packages first, every time, because we’ve seen neighbors lose six weeks reworking plans.
- Builder-grade cabinets that don’t line up with non-standard framing. Older Irvine tracts from the 1980s and 1990s weren’t built to modern cabinet dimensions. We measure and adjust rather than forcing a standard box into a wall that’s off by an inch and a half.
- Overlooking wildfire-zone requirements in foothill villages. Turtle Rock and Portola Springs sit in designated fire zones. Ember-resistant vents, Class A roofing, and defensible-space detailing aren’t optional. We’ve had inspections fail because a previous contractor skipped these, and it cost the homeowner three extra weeks.
- Assuming all Irvine homes are the same. A Woodbridge townhome built in 1978 has different framing, HOA rules, and stucco conditions than a Great Park home from 2018. We treat each village on its own terms, not as a generic Irvine job.
Our crew recently completed a kitchen remodel in a Woodbridge townhome where the homeowner wanted to remove a wall to open up the floor plan. We discovered it was load-bearing and needed a beam, which required a change order and an inspection sign-off before drywall. We also helped them navigate the HOA’s architectural review for new exterior paint colors, getting approval before we even pulled the permit. That’s the sequence in Irvine: HOA first, then city, then build.

FAQs About General Contractor in Irvine
Yes, for exterior modifications in most Irvine villages, you need architectural approval from your HOA design-review board before the city will accept your permit application. Interior remodels typically skip the HOA step unless you’re changing windows, doors, or rooflines. We prepare the architectural package first so you don’t lose weeks on a rejected submittal. Call (855) 382-3257 if you’re not sure whether your project needs HOA sign-off.
Builder-grade cabinets, laminate countertops, and standard windows are the most common first upgrades in Irvine’s 1990s and 2000s tracts. A cabinet replacement runs $4,000 to $13,000, countertops start at $2,000, and window replacement averages $4,500 to $15,000. These are the upgrades with the fastest return on daily comfort in a home you’re planning to keep. Call (855) 382-3257 for a free estimate on any of them.
The short answer is to leave structural and envelope work to the builder’s warranty terms, and route any modifications through a licensed contractor who documents the scope. In Irvine’s newer Great Park homes, the builder warranty often covers framing and roofing for a set period, but only if unmodified. We check your warranty language before we touch anything structural and work around it rather than through it. Call (855) 382-3257 with your warranty details and we’ll walk through what’s safe to remodel.
Homes in Turtle Rock and Portola Springs sit in designated wildfire zones, which means ember-resistant vents, Class A roofing, and specific exterior materials are mandatory on any remodel that touches the building envelope. A roof replacement in these villages must meet Class A standards, which typically means GAF, CertainTeed, or Tamko systems with the right underlayment. We handle the fire-code details as part of the permit package. Call (855) 382-3257 for a scope review in your foothill village.
A standard kitchen remodel in Irvine runs 6 to 10 weeks from demolition to final inspection, assuming no structural changes and smooth HOA approval. Adding a load-bearing beam, changing the footprint, or routing through a slow design-review board can add 2 to 4 weeks. We give you a written timeline before we start and update it weekly. Call (855) 382-3257 to get a timeline for your specific kitchen.
