Terms and Conditions
Effective January 1, 2026
Alliance Walnut Creek Concrete Company, walnutcreekconcretecontractor.com, projects@walnutcreekconcretecontractor.com
Accepting these terms
These terms apply when you use this website or hire Alliance Walnut Creek Concrete Company for concrete work. By browsing the site, asking for an estimate or booking a job with us, you agree to them.
If a signed contract or written proposal for your job says something different from these terms, the signed document controls for that job. If you don't agree with these terms, please don't use the site, and talk to us before any work is scheduled.
What we do
We're a concrete contractor in Walnut Creek, CA. We build driveways, patios, sidewalks, steps, pool decks, garage floors, slabs, footings, foundations and retaining walls, and we do stamped and decorative concrete, concrete cutting and related work. You can see the full list from our home page and read more about our crew on our About page.
Descriptions, photos and examples on this site show the kind of work we do. They aren't a promise that your job will look the same, because every yard, slope and soil condition is different. The scope of your job is whatever your written estimate or contract describes.
Estimates and pricing
We give free in-person estimates with no obligation. We base an estimate on what we can see and measure on the visit, including the size of the area, access for our equipment, the condition of what's there now, the finish you pick and how much old concrete or soil has to come out.
An estimate is our best price for the work as described. Some conditions stay hidden until the old slab is removed or the ground is dug out, such as soft or wet subgrade, which is the soil the new slab sits on, buried roots, old footings or debris. If we find something like that, we'll stop, show you, explain the options and give you the added cost in writing before we go ahead.
Changes you ask for after the work is agreed, like a larger area, a different finish or added steps, may change the price and the schedule. We'll confirm any change with you before we do it.
Unless your estimate says otherwise, an estimate is good for 30 days, because material and disposal costs move.
Scheduling, weather and cancellation
We schedule pours around the weather, because concrete poured in rain or very hot afternoons can end up with a weak, dusty top. If conditions on the day would put the quality of your slab at risk, we'll reschedule and let you know as early as we can. A weather delay isn't a breach of our agreement by either side.
Delays can also come from permit timing, inspections, material supply or site conditions outside our control. We'll keep you informed and get back on schedule as soon as we're able.
If you need to cancel or move your date, please call us at (925) 448-9528 as soon as you know. Your written contract will say whether any deposit is refundable and whether costs already spent, like ordered materials or completed demolition, will be charged.
Your part in the job
You agree to give our crew safe access to the work area, to move vehicles, furniture and anything else that's in the way, and to tell us about sprinkler lines, buried wiring, septic parts or private utilities we wouldn't otherwise know about. We aren't responsible for damage to unmarked private lines that you didn't point out.
You're responsible for knowing where your property lines are and for any approval your homeowners association requires. Some jobs need a permit from your city, and your contract will say who handles it for your job.
New concrete has to cure, which is the time it needs to harden before it can take weight. We'll tell you when it's safe to walk and drive on it. Damage caused by using the slab too early, or by people, pets or vehicles crossing it against our instructions, isn't covered by us.
Payment
Your contract will list the deposit, if any, the payment schedule and the payment methods we accept. Unless it says otherwise, the balance is due when the work is complete.
If a payment is late, we may pause remaining work until it's paid. Under California law, contractors who aren't paid can have lien rights on the property they improved, and we may use them if a balance goes unpaid.
What concrete will and won't do
Concrete is a natural material, and some cracking is normal over time. We cut control joints, which are planned grooves that give the slab a place to crack in a straight line instead of at random, and we dig out and pack the base so the slab doesn't settle with loose dirt. That lowers the chance of problem cracks, but nobody can promise a slab that never cracks.
Small differences in color, texture and finish from one section to another, and from samples or photos, are normal and aren't defects. Stamped and colored concrete in particular will vary from pour to pour.
Our satisfaction guarantee and any written warranty for your job are described in your contract. Beyond what your contract states in writing, and to the extent California law allows, we make no other warranties, express or implied, including implied warranties of merchantability or fitness for a particular purpose.
No warranty covers damage from earth movement, tree roots, flooding, heavy loads the slab wasn't built for, deicing salts, chemicals, lack of maintenance, or work done by someone else after we finish.
Limits on our liability
To the extent California law allows, our total liability for any claim connected with a job is limited to the amount you paid us for that job. We aren't liable for indirect, incidental or consequential losses, such as lost use of a driveway, rental costs or lost income.
Nothing in these terms limits liability that can't be limited under California law, including liability for our own gross negligence or willful misconduct.
Using this website
The information on this site is general and is meant to help you understand concrete work. It isn't engineering, legal or permit advice for your property, and it doesn't replace an on-site estimate.
We try to keep the site accurate and current, but we don't guarantee that every page is complete or free of errors, or that the site will always be available. Links to outside sites are there for your convenience, and we aren't responsible for their content.
The text, photos and design of this site belong to Alliance Walnut Creek Concrete Company or are used with permission. Please don't copy them for commercial use without asking us first.
Resolving a disagreement
If you're unhappy with any part of our work, call us first. Most problems get settled quickly once we come out, look at it together and agree on a fix.
If we can't settle it that way, both sides agree to try mediation in good faith before filing a lawsuit, unless the claim belongs in small claims court. Any lawsuit will be brought in the courts of Contra Costa County, California.
Governing law
These terms, and any work we do for you, are governed by the laws of the State of California, without regard to rules that would apply another state's law.
Changes to these terms
We may update these terms from time to time. The version on this page when you use the site or sign your contract is the one that applies, and changes won't alter a contract you've already signed.
Questions about these terms
If anything here is unclear, call us at (925) 448-9528 or use our Contact page, and we'll walk you through it before any work begins.
