Fast, Reliable General Contractor Across Santa Ana
If you’re planning a remodel or addition in Santa Ana, the real decisions happen after the first wall comes down. A general contractor in Santa Ana needs to know what lives inside these older homes: cloth-wired circuits, galvanized supply lines, shallow slabs, and framing that met code in 1947 and hasn’t been looked at since. We approach every project here with that expectation, not as a surprise fee but as the reason you bring in a full-scope contractor in the first place. Our team works across 92701, 92702, 92703, 92704, 92707, 92735, and 92799, and we’re set up to quote, permit, and build without subcontractor chaos. Call (866) 253-5808 to talk through what you’re planning.
Why Timberline Contractors Is Santa Ana’s Preferred General Contractor Company
Nelson Fung founded Timberline Contractors on a simple idea: one contractor should own the outcome from foundation to ridge cap. In Santa Ana that matters more than in newer markets, because the typical job here involves a 1940s bungalow that needs rough-in corrections before any finish work starts. Homeowners in the 92701 and 92703 core regularly tell us they were quoted by someone who never looked behind the stucco. We do look. That inspection-first process is why Santa Ana customers bring us back for second and third projects, and why they refer us to neighbors along the older corridors off Main Street, Edinger Avenue, and Bristol Street.
We’ve built our local reputation by writing allowances for the code upgrades these houses trigger once walls are open. When a Santa Ana homeowner sees a line-item allowance for wiring or a galvanized repipe before the contract is signed, they know we’ve done this before. That transparency, backed by a roster of 50-plus material partners including GAF roofing, James Hardie siding, Kohler plumbing, and Cambria quartz, gives clients true material choice without losing single-source accountability. We bring the showroom to the project. It changes the conversation from “what can you get me” to “what do you actually recommend for this house.”
Our General Contractor team responds to every Santa Ana lead with a scheduled site visit, not a callback to a call center. We know the difference between a 1920s pier-and-beam in 92702 and a 1950s slab in 92704, and we quote accordingly. Estimates are free, written, and line-itemed. No allowances buried in the back. Call (866) 253-5808 and you’ll know what the job costs before you commit to it.

Hire a General Contractor in Santa Ana
Hire a General Contractor in Santa Ana when the project touches more than one trade, or when the house is old enough that the walls hold surprises. Most jobs we take on here fall into that second category. A kitchen remodel in a 1930s stucco bungalow off 92701 is rarely just cabinets and counters. It’s rewiring circuits that were installed before grounded outlets existed, opening walls to fix undersized framing, and pulling a permit that triggers current code requirements for the work you can now see. Santa Ana homeowners pay a general contractor to manage exactly that sequence, so the job doesn’t stall when the unexpected shows up. A kitchen remodel here typically runs $14,000 – $45,000 depending on scope and material tier. A smaller kitchen sits in the $9,000 – $20,000 range, and countertop work runs $2,000 – $6,500.
One Contract, Not Five
We handle the entire job: framing, plumbing, electrical, drywall, tile, flooring, paint, and the final walk. That means one contract, one draw schedule, one warranty. When the electrician and the framer disagree about sequencing, you don’t referee. Nelson Fung’s team manages the field and the paperwork, and every change is priced and approved in writing before we move.
Allowances Written Before Walls Open
On older Santa Ana stock, we write allowances for wiring, plumbing, and framing corrections into the original contract. It’s the honest way to quote a remodel on a house built before 1950. If the allowance isn’t needed, you don’t pay it. If it is, you approved the range up front, and the change order is a formality, not a fight.
General Contractor Services in Santa Ana
General Contractor Services in Santa Ana cover the full scope: kitchen and bath remodels, whole-home renovations, room additions, garage conversions, ADUs, roofing, siding, windows, fencing, hardscaping, and exterior envelope work. A typical whole-home remodel of an older Santa Ana bungalow runs $14,000 – $45,000 per major space depending on finish level, while a bath remodel sits at $9,000 – $28,000. Room additions on the small lots common in 92703 and 92704 start around $45,000 and can reach $130,000 for a well-finished primary suite. Garage conversions, which we do constantly in this market, run $30,000 – $80,000, and full ADU construction falls in the $90,000 – $220,000 range depending on site constraints, utility runs, and material selection.
Garage Conversion ADUs Done Right
In Santa Ana’s older core ZIPs, the garage-conversion ADU is the single most common permit pulled. That’s our bread and butter. We don’t treat a garage like a cosmetic remodel; we evaluate the slab, the wall framing, the electrical service, and the roof structure first, then write the contract around what living-space code actually requires. A garage built for parking in 1952 needs different framing and insulation than a studio someone sleeps in.
Interior and Exterior Under One Roof
Most Santa Ana remodels eventually touch the outside of the house. A kitchen remodel exposes a rotted window header, which leads to a siding repair, which leads to a roofing edge detail. We handle that sequence internally instead of referring you to three separate crews. One contractor, every phase, from the foundation to the ridge cap.

Trusted Brands We Service in Santa Ana
We are a general contractor, not a showroom salesman, so we’re not married to one manufacturer. We are partnered with more than 50 brands across every category, and we spec what the project needs. That means General Contractor in Santa Ana work can include Techo-Bloc pavers for a courtyard patio that handles the dry Santa Ana summer heat without fading, Unilock wall systems for lot-line retaining on tight urban sites, and Cambridge Pavers when the client wants a wider color range for a driveway that replaces a cracked 1960s slab. We keep local material access fast, and our suppliers serve the 92701 through 92707 corridor directly, so lead times don’t stretch out because we’re pulling from a warehouse across the state.

AfterCommon General Contractor Problems We See in Santa Ana Homes
- Cloth-wrapped or knob-and-tube wiring behind finished walls. A 1920s or 1930s bungalow in 92702 almost always has some of this still live. Opening a kitchen or bath wall without a wiring allowance in the contract is how remodel budgets blow up mid-job.
- Galvanized supply lines that have rusted inward. The water pressure looks fine at the hose bib but drops at the second-floor fixtures. On a Santa Ana remodel, we check the service and branch lines early, because repiping after tile is set is a five-figure mistake.
- Undersized framing and scabbed-in headers from decades of handyman work. These 1930s and 1940s bungalows were built with 2×4 walls and sometimes got questionable “repairs” over the years. If the permit inspector sees it, you’re correcting it. We’d rather find it before the inspector does.
- Low-slope roofs failing at seams and flashing. The dry Santa Ana winds and near-zero rainfall mean these older bungalow roofs don’t die from snow load. They die slowly at the seams, and the leak shows up inside a kitchen ceiling three years after it started. Roof condition routinely surfaces mid-remodel once walls are open, and we handle it as a scope item, not a surprise.
Pricing for General Contractor in Santa Ana, CA
Every price on this page is what we actually see in the Santa Ana market, not a national average. The biggest variable is the condition of the house behind the drywall. A clean 1990s remodel with no framing or wiring corrections will land at the low end. A 1935 bungalow with original wiring and a failing low-slope roof will land higher. The table below shows what we’re quoting across the 92701 through 92707 corridor and the surrounding ZIPs. Estimates are free, and every allowance is written in the contract before you sign.

FAQs About General Contractor in Santa Ana
Because most homes in the older core ZIPs (92701, 92703, 92704, 92707) were built between the 1920s and 1950s, and the wiring, plumbing, and framing behind the drywall rarely meet current code. A kitchen wall may hide cloth-wrapped circuits, undersized headers, or galvanized pipe that a permit requires us to bring up to standard. We write allowances for those corrections into the contract so the quote moves by an approved amount, not a surprise one. Call (866) 253-5808 for a quote that accounts for what’s actually behind your walls.
Yes. A garage converted to living space in Santa Ana requires a building permit and must meet current code for insulation, electrical service, egress, ventilation, and foundation anchorage. The slab, framing, and rough-in work on a garage built for parking almost always need correction before finish work starts, which is why a garage conversion here runs $30,000 – $80,000 rather than just what flooring and drywall cost. Call (866) 253-5808 to walk through your specific garage.
We treat them as a remodeling variable from day one. Low-slope and flat roofs on 1930s and 1940s bungalows fail at seams and flashing rather than from load, thanks to the dry Santa Ana winds and near-zero rainfall. If we’re opening walls below a low-slope roof, we inspect it early, and we write any repair scope into the same contract rather than pushing it off to a separate roofer after the project ends. Call (866) 253-5808 and we’ll include the roof condition in your estimate.
Everything from the first inspection to the final punch list. We hold the license and the insurance, we pull the permits, we schedule and supervise every subcontractor, we write and approve every change order, and we sign off on the final walk. You get one phone number, one draw schedule, and one warranty on the whole job. That’s the difference between hiring a general contractor and trying to coordinate five trades yourself. Call (866) 253-5808 to discuss what your project needs.
For an attached room addition, budget $45,000 – $130,000 depending on square footage, finish level, and foundation type. A detached or garage-conversion ADU in Santa Ana runs $30,000 – $80,000 for garage work and $90,000 – $220,000 for full new construction, with the spread driven by utility runs, site access, and whether the slab needs structural correction. Those ranges come from what we quote in 92701, 92703, 92704, and 92707, not a national calculator. Call (866) 253-5808 for a written estimate on your specific lot.
