Altadena is mostly older houses on their own lots
Altadena sits just above Pasadena and close to La Cañada Flintridge, and it's mostly single houses on their own lots, a lot of them older, with plenty of historic properties among them.
On our jobs there, the concrete we're replacing has usually been down a long time, and the old driveways, walks and steps show it, with cracks, settled sections and slabs pushed up by tree roots. Plenty of lots also climb toward the mountains, so a patio or driveway often needs a wall or a set of steps to handle the grade. That's why I start with what's underneath and where the water goes, because on these properties that's what decides whether new concrete holds up.
Concrete work we do in Altadena
Concrete driveway building
Older Altadena driveways are often cracked, sunk or lifted at the joints, and rebuilds need a new one, so we dig out the base before we pour.
See the service Concrete driveway buildingConcrete patio construction
On older lots here a worn patio often tilts toward the house, so we reset the grade and pitch the slab so water runs away from the walls.
See the service Concrete patio constructionStamped concrete services
Stamped concrete gives a patio or walk the look of stone or brick, which suits the older styles of house you see around Altadena.
See the service Stamped concrete servicesConcrete sidewalk building
Front walks here are often heaved by roots or broken into trip edges, so we tear them out and pour a level path with proper joints.

Detached garages on Altadena lots often have thin, cracked floors, and a rebuilt garage needs a new slab that can carry a car's weight for years.
See the service Garage floor concreteDecorative concrete
Colored and textured finishes let new concrete sit easily next to a house with some age on it, so a redone yard doesn't look like a fresh gray slab.

Sloped yards near the foothills often need a wall to hold the grade, and we work out the footing and the drainage behind it before anything gets poured.
See the service Concrete retaining wallsConcrete floor installation
Workshops, studios and additions on Altadena homes sometimes need a new floor slab, and we find out what's under the old one before we pour.

When an Altadena backyard gets redone, the pool deck often comes with it, so we give it a textured finish and slope it toward the drains.
See the service Concrete pool decksConcrete steps construction
Many homes here sit above the street with worn, uneven front steps, so we form new ones with even step heights that are easy to climb.
See the service Concrete steps constructionSlab foundation building
Houses being rebuilt here often start from a new slab, and we spend our time on the ground under it because that's where trouble begins.
See the service Slab foundation buildingFoundation installation
For rebuilds and additions on Altadena lots, we lay out and pour the foundation the plans call for, raised or slab, with the steel set where it belongs.
See the service Foundation installationConcrete parking lot building
Shops, offices and small apartment buildings here need parking that drains and holds up to daily cars, so we build a thicker base underneath.
See the service Concrete parking lot buildingConcrete footings
Walls, posts, additions and garden structures on Altadena lots all need footings, the buried concrete that spreads the load, and we dig them to solid ground.
See the service Concrete footingsFoundation raising
When an older Altadena house has settled and doors stick or floors slope, we work out why it moved before anybody lifts it.
See the service Foundation raisingConcrete cutting
On Altadena houses with some years on them, cutting lets us take out a cracked section or open a slab for plumbing without tearing out the whole thing.

What working in Altadena means for permits and price
Because Altadena is unincorporated, there's no city hall here, and Los Angeles County acts as the local government. Permits come from LA County Public Works, whose list names patios, retaining walls, pools, grading, new buildings and additions, so a good share of what we pour here goes through that office and the schedule follows its inspections. Driveways and walks aren't spelled out on that list, so when we're not sure, we check with Public Works before we start. As for licenses, Altadena has no city business license to look up and the county licenses only a set list of business activities, so the one to ask any contractor about is their state contractor license. We're fully licensed and insured.
What moves the price here is mostly the ground and the access, since some streets climb steep and narrow and a truck can't always pull up close to the forms. What moves the schedule is the permit, when there is one, plus the curing time before you can use the new slab, and your own figure comes with the estimate. As a concrete contractor in Glendale, CA, we're a short drive away, and we do the same work nearby in South Pasadena and Sierra Madre.
Altadena properties need concrete for two main reasons
Since the Eaton Fire hit Altadena in January 2025, a lot of the lots we walk are coming back from bare ground, with new footings, slabs, driveways and walls going in. Before anyone decides to keep old concrete that went through the fire, I want a close look at it. On the new work I put the most care into the base, because it's hidden on day one and it's the first thing people want to cut from the budget, but everything else sits on it.
On the older houses, the calls are cracks, sinking and water pooling against the walls, usually from a base that was raked flat instead of dug out and packed, a slab that tilts toward the house or joints nobody cut. We go after the cause, packing a firm subgrade, the ground the slab sits on, and cutting control joints, shallow grooves that tell the slab where to crack, so any cracking lands where we chose.
How a concrete job runs when you call us in Altadena
Here's how it goes from your first call to the final walk-through, and what you'll get from us at each step.
Call us or send the form
Call (747) 372-8605 or send the form with a few words about the job and where it is in Altadena. We get back to you and set a time for me to come out.
I look over the site
I check the ground, where the water runs and what's under any old concrete, and I ask a lot of questions, so it helps if you're there. You get a written estimate that spells out what's included, so you know what you're paying for before you decide.
We permit, pour and walk it
Once you say go, we pull any permit and line up the county's inspections, then our own crew digs out and packs the base, pours, finishes and cuts the joints with me running it. At the end we walk the job together so you can see every part of it.
Questions about concrete work in Altadena
How do I find out if my concrete project in Altadena needs a permit?
Enter your street address or parcel number on the county's Public Works permit site and click Find Services, and it shows which office handles permits for your property. Once a permit is issued, the county wants the first inspection requested within 12 months and a follow-up every 6 months to keep the permit active, so we schedule those as the job moves along.
What counts as a like-for-like rebuild in Altadena after the Eaton Fire?
LA County Planning calls a rebuild like-for-like when it's the same size, location and use as the legally established structure that stood there. Changes can still be approved if they add no more than 10 percent or 200 square feet, whichever is greater, to the floor area, size, height or footprint. Go past that and the rebuild has to meet the county's current standards for Altadena, including a front yard setback of at least 20 feet, which can change where a new foundation and driveway go. The county's Altadena One-Stop Permit Center offers residents free virtual appointments to go over rebuild plans and permits.
What should a contract for concrete work or a fire rebuild in Altadena include?
California's Contractors State License Board says any home improvement job over $500 needs a written contract that says who will get the permits and gives a completion date. For rebuilding after a wildfire or another declared disaster, the board says the contractor must use a fixed price contract and can't ask for or take a down payment of more than $1,000 or 10 percent of the contract price, whichever is less. If a bid you're handed doesn't line up with that, ask why before you sign.
How much does a concrete driveway or patio cost in Altadena?
There's no single price, because a driveway or patio here is priced on its size and on what has to happen under it, and I won't know that until I've seen the lot. Breaking out and hauling an old slab, digging down to firm ground for the base, adding rebar, the steel inside a slab that holds it together if it cracks, and stamping or coloring the top all raise the price, while a plain broom finish, a lightly brushed texture that gives shoes and tires grip, keeps it down. If the budget's tight, I'd rather trim the finish than the base, because the base is what keeps the slab from sinking.
How long until I can use my new concrete driveway in Altadena?
You can walk on new concrete well before you can drive on it, because it keeps gaining strength while it cures, the waiting period while it hardens. If the job needs a permit, the county's inspections add time before the pour. When we walk the finished job together, I'll tell you when it's ready for feet and when it's ready for the car.
Do I need a permit to pour concrete near an oak tree in Altadena?
You may, because depending on location LA County protects oak trees and other native trees, and development work within a protected tree's zone normally needs a permit. On a fire rebuild, the exception only covers a legally established structure that already stood in that zone on the day the disaster damaged or destroyed it. If there's an oak near your driveway or patio, we sort that out before anyone digs, since the roots usually run well past the trunk.
