Fast, Reliable General Contractor Across Fullerton
Ashbury Contractors handles whole-property construction and remodeling across Fullerton, from downtown bungalow updates to acreage builds in the 92835 hillsides. Most Fullerton homeowners call us when they need one accountable contractor across multiple trades rather than juggling separate crews. Call (833) 467-4091 for a free estimate, and we’ll walk your property with you before quoting a number.
Fullerton is not a single building market. A 1920s Craftsman near downtown and a 1960s ranch in the 92833 flats present completely different framing, wiring, and permitting realities. We have worked every block type in this city, and that local knowledge shows up in our scopes of work, not just our marketing.
Why Ashbury Contractors Is Fullerton’s Preferred General Contractor Company
Noel Quintero founded Ashbury Contractors to give homeowners one point of contact from the foundation to the fence line. In Fullerton, that matters more than in most cities because housing stock shifts block by block. A remodel on one street pulls original plaster and pier-and-beam subfloors. Three blocks over, it is slab-on-grade with post-and-beam framing. We scope both correctly the first time.
Fullerton customers keep calling us back because we specify the product before we quote the price. When we bid a kitchen remodel, the countertop brand, cabinet line, and fixture manufacturer are named in the proposal. No vague allowances you have to sort out later. That approach works whether we are replacing windows in a 92832 bungalow or building a detached ADU off a hillside drive in 92835.
We are licensed, insured, and bonded. Our crews know Fullerton’s permit paths, including where county jurisdiction kicks in on acreage parcels. That county-versus-city split catches a lot of contractors off guard. It does not catch us.
Styles & brands we work with
General Contractor Services in Fullerton
General Contractor Services in Fullerton means we run the entire job: demolition, framing, rough and finish trades, inspections, and the final walk. A homeowner needs us when the project spans multiple trades and the idea of coordinating a plumber, electrician, roofer, and cabinet installer separately sounds like a second job. A full kitchen remodel in Fullerton typically runs $14,000 to $45,000 depending on cabinet line, countertop selection, and how much wall movement the layout requires.
Kitchen and Bath Remodels
We spec Cambria, Caesarstone, or Silestone countertops before quoting. Cabinet lines come from KraftMaid and other vetted manufacturers. Fullerton homeowners in older homes often need us to correct out-of-level floors and non-square walls before cabinets go in, which is exactly the kind of thing a paint-and-tile crew will not catch until the countertop template shows a half-inch gap.
Whole-Home and Phased Work
Some Fullerton clients start with a kitchen and add bathrooms, windows, and fencing over two or three years. We keep material selections documented across phases so finishes stay consistent. That continuity matters when the first phase is a 1920s exterior window upgrade and the third is a modern kitchen in the same house.

Construction Company in Fullerton
A Construction Company in Fullerton working acreage, hillside, or flag-lot parcels has to manage county permitting, well and septic setbacks, long material hauls, and grading before quoting a single line item. In the 92835 hills and unincorporated pockets, a detached ADU typically runs $90,000 to $220,000, and a garage conversion runs $30,000 to $80,000. Home additions start around $45,000 and reach $130,000 depending on foundation type, utility runs, and site access.
Acreage and Outbuilding Scope
We build detached shops, ADUs, and outbuildings under one contract. When a parcel sits in county jurisdiction, the septic and well setbacks often determine where the building pad can go. We run those checks before we quote, which means the price you see is the price the county will actually permit.
Grading and Drainage on Open Lots
Fullerton’s hot, dry summers and Santa Ana wind episodes dry out expansive soils and open up cracks. When the rainy season hits, runoff on an open lot will find the lowest point, which is often your new slab. We design grading and drainage as part of the structural scope, not as a line item added after the first storm.
Trusted Brands We Service in Fullerton
Fullerton homeowners get access to more than 50 name-brand product lines through Ashbury Contractors. For windows and doors, we install ES Windows, ECO Window Systems, Mr-Glass, and Therma-Tru. For roofing, we work with GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral. Countertop lines include Cambria, Caesarstone, and Silestone. Plumbing fixtures come from Kohler, Grohe, and Toto. When we quote a Fullerton job, the brand is in the proposal. We do not substitute mystery materials.

AfterCommon General Contractor Problems We See in Fullerton Homes
- Original plaster and knob-and-tube-era framing. Downtown Fullerton bungalows from the 1910s through the 1930s often hide old wiring and plaster walls behind modern drywall patches. Opening a wall reveals scope nobody quoted for.
- Pier-and-beam subfloors meeting slab additions. Many Fullerton homes are half original, half added on. The transition between foundation types moves independently, and we have to account for that before setting tile or cabinets.
- Stucco cracking from the Santa Ana cycle. Fullerton’s dry summers and hot wind episodes shrink expansive soils. Older stucco develops hairline cracks that let water in during winter rains, and that turns into framing rot behind the wall.
- County-versus-city permitting on acreage. In Fullerton’s 92835 hillside parcels, the property may sit in unincorporated Orange County territory. Septic and well setbacks fall under county rules, and a city-style plan gets rejected at the permit counter.

FAQs About General Contractor in Fullerton
If the parcel sits in unincorporated Orange County, the county reviews the permit, including septic and well setbacks. If it is within Fullerton city limits, City of Fullerton planning and building departments handle it. We verify jurisdiction before quoting, because the plan path changes everything about the price and timeline. Call (833) 467-4091 and we will check your parcel.
Setbacks from the septic tank, leach field, and wellhead determine where the building pad can sit. On a small or awkward acreage parcel, that can force foundation adjustments, longer utility runs, or a smaller footprint. Those changes hit the price before any wall goes up. We confirm setbacks during the estimate, not after the permit is filed.
Fullerton gets long dry stretches and then concentrated winter rain. On an unpaved lot, stormwater flows downhill and pools at the lowest point, which is often against a new slab or outbuilding. Proper grading and drainage keep runoff moving away from the structure. We design that into the scope on every acreage project.
The scope should name the permit path, foundation type, framing, utility runs, material brands, and a line-item allowance for grading, drainage, equipment access, and hauling. If a contractor will not put those in writing, walk away. We lock scope and allowances before breaking ground on every Fullerton job. Call (833) 467-4091 for a written proposal.
We inspect the access route during the estimate and price the haul distance, turnarounds, and any staging limitations up front. On steep or flag-lot parcels in 92835, equipment access can add thousands to the real cost. We put that in a stated allowance so it never shows up later as a surprise change order.
On an acreage lot off the hillside edge near 92835, our crew scoped a detached shop and ADU where the existing well and septic set the building pad, forcing us to pull county permits and design grading and drainage to push stormwater away from the leach field. We locked the scope of work and allowances in writing before breaking ground, posted a draw schedule around the long material hauls up the narrow driveway, and walked the punch list with the owner after inspection sign-off.
That is how we build in Fullerton. One contractor, every trade. From the foundation to the fence line. Call (833) 467-4091 to schedule your free estimate.
