Concrete That Cracks Is Almost Always a Preparation Problem
Most concrete failures happen before a single yard gets poured. The ground wasn’t properly graded. The base rock wasn’t compacted. Rebar wasn’t placed where it needed to be, or wasn’t used at all. The mix wasn’t right for the conditions. Then the concrete goes down, it looks fine for a year or two, and then the cracking starts.
By that point, the contractor is long gone.
Concrete is a trade where the work you don’t see matters as much as the work you do. The base prep, the reinforcement, the curing process, these are the details that determine whether a driveway or patio holds up for twenty years or starts showing problems in two. Cutting corners on any of them doesn’t show up on pour day. It shows up later, and it shows up in the concrete.

How We Approach Your Concrete Job
Licensed General Contractor | Lic #1133241
I’m John Collins. I handle concrete work as part of JCW’s in-house trade scope, driveways, patios, walkways, and foundations. Every pour starts with preparation done right.
1. The base work gets done before anything is poured
Proper base preparation isn’t optional, it’s what determines whether concrete holds up long-term. Grading, compaction, base depth, and drainage are assessed and handled before a single yard is ordered. If the base isn’t right, the concrete isn’t right.
2. Reinforcement is included, not optional
Rebar and wire mesh aren’t upsells, they’re part of what makes concrete structural. JCW includes reinforcement as standard on driveways, patios, and any pour where the concrete is expected to bear load. You get concrete that’s built to last, not bid low and fail early.
3. The scope is scoped honestly
Concrete projects often involve more than just the pour, existing concrete removal, grading, drainage considerations, and finishing details. JCW scopes the full job before putting a number in front of you. What’s in the estimate is what’s in the project.
4. Finish and cure
Concrete finish, whether broom, brushed, or exposed aggregate, is part of the scope discussion. Curing is handled correctly to prevent surface cracking. The job isn’t done when the pour is done. It’s done when the concrete is properly cured and ready.

How ConcreteWork With JCW Gets Done
No two remodels are identical, but the process is consistent.
1. Site assessment and honest scoping
John comes out, evaluates the site, and scopes the full job, including existing concrete removal, base depth requirements, drainage, and reinforcement. You get an estimate that covers what the project actually requires.
2. Base preparation before anything gets poured
Grading, compaction, and base prep are completed before the pour is scheduled. Reinforcement is placed and inspected. The base is right before the concrete goes down.
3. Pour, finish, and cure
The concrete is poured, finished to the agreed specification, and cured properly. John manages the full process and does a final walkthrough before the project closes.
⭐⭐⭐⭐⭐ Lisa K.
I am in Petaluma and hired JCW Construction to complete a list of projects that have been on my list for a very long time. Their team replaced/upgraded all of my ceiling lights, fixed the bathroom ceiling fan and installed 2 ring cameras. I am in love with my new lights!
My experience could not have been better! They were prompt, courteous and professional. Their services were also very reasonably priced. If you need any electrical work, please consider contacting them. You will not be disappointed.

Frequently Asked Questions About Concrete Work in Santa Rosa
How long does concrete last if it’s installed correctly?
A properly prepared and reinforced concrete driveway or patio can last 25-40 years with basic maintenance. The variables are base preparation, reinforcement, and the quality of the pour and cure. Concrete that cracks within the first few years almost always has a preparation problem at the root.
How long does a concrete project take?
The preparation and pour phase for a standard driveway or patio typically runs two to three days. Concrete then needs time to cure before it can carry vehicle or heavy foot traffic, typically seven days for initial use, with full strength at 28 days. John will walk you through the timeline at the estimate stage.
Do you remove and haul away old concrete?
Yes. Existing concrete removal and disposal is included in the JCW scope where it’s part of the project. This is factored into the estimate upfront, not added as a separate line item later.
Do permits apply to concrete work?
It depends on the scope. Foundation work and some structural pours require permits in Sonoma County. Driveways and patios typically don’t, though there are exceptions depending on the location and drainage impact. JCW will confirm what applies to your specific project at the estimate stage.
Do you work in Marin County and the East Bay?
Yes. JCW handles concrete work across Sonoma and Marin County, the East Bay, and the Fairfield/Vallejo corridor. John manages the work personally in all markets.
