Crew troweling a fresh concrete slab at a Fullerton house — 14Years on crews before 2021

Our story

C-8 Licensed, Working Out of Fullerton

Harbor Fullerton Concrete is a concrete contractor run out of a yard on Harbor Boulevard in Fullerton, CA. Grant Yoshida founded it in 2021, having spent 14 years on north Orange County crews first, and the work now reaches 20 towns across Orange and Los Angeles counties, none of them more than 25 miles out.

The work is residential and light commercial: drives, patios, garage and interior floors, walks, steps, walls and footings. One crew runs a job from breakout to the final walk, and the man who measured it is on site for the pour. Every job leaves with a written workmanship guarantee against defects in how it was built.

The classification is C-8 Concrete, on file with the California Contractors State License Board. liability insurance on every job is carried on every site, permits are lodged by us rather than left with you, and one of the crew stands the inspection. Every estimate is measured and written on site.

The man with the tape

Grant Yoshida Writes the Figure and Stands the Pour

14 years on crews he did not run came before the license, most of them on the flat postwar tracts between Harbor and State College. Every figure quoted on this site was written by him, on the property it belongs to.

Founder, digs the test hole, writes the figure

Grant Yoshida

CSLB C-8 holder, Fullerton resident, in concrete since 2007

Grant Yoshida first went out as a laborer on a flatwork gang at eighteen, and four summers went by on the screed before anything else did. By his late twenties the trowel end was his, and the twenty minutes after the last truck pulls out is where a surface is decided for the next thirty years. 14 seasons in this county is enough to have dug through most kinds of ground it holds, and enough to have been called back to the handful that later shifted.

He lives ten minutes from the gate and answers the phone on this site himself. The one thing he will not do is price a lot he has not walked. On a postwar block the top of the ground tells you almost nothing about what sits beneath a drive, old trench spoil, a filled pool, a slice of hillside cut and pushed back level, and none of that is visible from the curb, which is where a quick quote gets written.

Nothing on this page needs his word for it. The classification is filed with the California Contractors State License Board under the business name, and the board's register is open to anyone. Cover is bound before a crew arrives, liability insurance on every job, and the certificate goes out to a homeowner or an HOA board for the asking. The terms behind the workmanship sit on the same sheet as the figure, so a question in year six is settled from paper rather than from memory.

“If the top foot digs easy, that is the ground lying to you. Open the second foot before anybody puts a price on the job.”

How the crew works

Six Rules That Hold on Every Fullerton Pour

Six rules, and not one of them bends for the size of a job. Each exists because of a particular way flatwork goes wrong on this ground: a base laid straight on the clay horizon, a joint grid cut too wide, a figure agreed before anybody opened the soil.

Say when not to pour

Plenty of the call-outs here are one lifted corner over a joint, and a saw and a grinder settle that. We say so, and lose the job.

The hole before the price

We open the ground while you watch and the depth to the clay goes on your sheet as a number. A drive costed from the curb is a guess in a suit.

Materials named, not implied

Mix strength, slab depth, the rock beneath it and the joint spacing go on your sheet as figures. A docket comes back off every truck.

One crew, one number

The men who set your forms finish your slab, and the figure you signed is the one invoiced. A change is initialled before anyone acts on it.

The exclusions said out loud

Seasonal movement, staining and the wear a car brings sit outside the guarantee. You are told which is which before signing, not after a claim.

Our name on the filing

Applications go in under the business, Building and Safety upstairs at City Hall, Public Works Engineering for anything past your line.

The dates behind it

From Screed Hand to a Fullerton Yard of His Own

Eight dates, oldest first. Everything before 2021 happened on somebody else's payroll, over 14 years of north Orange County flatwork; everything after it has happened under this name, out of the yard on South Harbor Boulevard.

2007

First season on flatwork

He went on as a laborer with a tract-work outfit at eighteen, tying steel and pulling screed through an Orange County summer.

2012

Onto the trowel end

Five years in, the finishing became his: the short window at the close of a pour that sets how the surface will wear.

2016

Running the crew

Scheduling and subgrade calls came to him, and that is where digging a lot open before quoting it turned into a rule.

2021

The C-8 and one truck

One truck, a license in his own name, and a first winter of drives and garage floors on the tract streets south of Commonwealth.

2022

The Harbor Boulevard yard

The business took a yard at 1310 S Harbor Blvd, south of downtown, where the plans, the dockets and the job files still sit.

2023

A second finisher

The payroll went to four, which is what it takes to break out, base, pour and joint a house drive without a week of standing about.

2024

Terms onto the estimate

What the guarantee covers went onto the sheet you sign, worded identically job to job, so year eight is settled from paper.

2026

Where it stands now

16 services listed, 20 towns over 2 counties, from La Habra at three miles out to Diamond Bar at ten, founder on every pour.

Check these yourself

Eight Fullerton Claims You Can Check Yourself

Eight statements, each one checkable at a public register, on a certificate or at a counter. Ask for the document behind any of them and it comes back the same day, rather than being held until a dispute makes handing it over unavoidable.

The C-8 classification

Concrete work is a C-8 in California. The California Contractors State License Board issues it and its register is searchable by business name.

Cover before day one

liability insurance on every job is bound before a crew arrives, and the certificate goes to you, or straight to an HOA board, unchased.

Workers' comp on the crew

Every man on site carries cover, so an injury on your property is answered by our policy and never by your homeowner's.

Filings under our name

Building and Safety takes the permit through the city's EasyDev portal; anything past your property line goes to Public Works Engineering.

The guarantee, printed

What it covers is on the sheet you sign, base, thickness, joint grid, finish, rather than described down a phone afterward.

A ticket for every truck

Every load turns up with a docket for its mix and its yardage, and that docket is stapled into your file before we leave.

The figure, on paper

Every estimate is measured and written on site. You keep the sheet, so what you set against another bid is paper, not a memory of a call.

One name on the reviews

Google, Facebook and the BBB carry this business under one name and no other. Worth reading for a job on ground like yours.

All six are countable

Six Numbers Behind the Fullerton Yard

Six figures and no adjectives beside them. Each is a count taken from the service list, the towns on the coverage page or the business record itself, so every one can be checked against the rest of this site instead of being taken on trust here.

The place itself

A Fullerton Week, Yard Gate to Property Line

The yard is at 1310 S Harbor Blvd, on the south side of the city, and it exists to load a truck and sign paper rather than to be visited. From that gate a working day runs north into the old townsite grid, west toward the county line at La Habra, or up into the folds under West Coyote Hills, where a 510-acre ridge is still the largest undeveloped piece of ground in north Orange County. Two lots forty feet apart in elevation can behave nothing alike.

The work sorts itself by what a property has to carry. Houses want a drive, a garage floor, a patio and the walk out front. The shops along Harbor and Commonwealth want aprons and bays that take a delivery truck rather than a car. Two campuses sit in the middle of all that, Fullerton College, teaching since 1913, and Cal State Fullerton with 45,863 students last autumn, so accessible walks and ramps built to a tolerance are ordinary work here rather than a rare job.

Beyond the boundary the coverage list is a short drive rather than a journey. La Habra starts three miles from the gate, Placentia and Brea inside five, Buena Park and La Mirada about the same, and Diamond Bar at ten is the far end of it. Half those towns are in Los Angeles County, so a second set of curb standards applies, and the encroachment side of a job is agreed with the right city before a date goes in the book.

Ring the yard or leave the form and somebody calls back within 1 business day to fix a time. Digging the hole, taking the measurements and setting the figure down on paper is free either way.
