Need a trusted concrete construction contractor in Sonoma County?

About Allen Winters

I grew up in this industry, learning it from my father. I got started as a Ready-Mix truck driver and eventually owned Sebastopol Ready-Mix, Dynamic Precast, and Rock Recycle. In 2005, Allen Winters Concrete was formed and became incorporated in 2018. I love working in the construction industry because of the challenge of making projects come together. Our crew of 5 full-time employees are highly skilled in concrete construction techniques for both commercial and residential projects.

We are a family owned and operated company, proud to be members of the community. Our long-standing, excellent relationships with local construction material suppliers ensure that we obtain materials on time and at the best prices for our clients.

“Allen is the real deal. Great experience, great crew, great getting permits, never misses a beat evokes confidence. I’d never use anyone else.”

“The crew did a great job matching the existing concrete. Saved me a ton of money because at first I thought I’d have to redo at least half if not the entire driveway. Great, fast, smart, and complete.”

Paul S.


“Extremely knowledgeable and reasonably priced. Knows the business inside and out. 40 plus years of experience. I did not even get a second bid, that’s how impressed I was!”

Chuck O.


“Allen and his professional team have helped to transform our backyard walkway and patio from an embarrassment to a source of pride. We highly recommend Allen Winters Concrete as they deliver what they promise and more and come up with creative solutions.”

Vicki & Chris C.


“It was a very easy experience dealing with Allen and his team. They did more then I expected and that makes me a delighted customer. They know their stuff and are very professional in delivering what they said they would do. They cleaned up everything after the job was done and didn’t leave until I was fully satisfied.”

“Did a great job and solved several serious drainage problems. His bid was about 10% below the other contractors and he did as good or better job than the other bidders would have done. His years of experience was a big plus with some of the problems we had. Also I should note he has a great crew of skilled concrete finishers.”

Alan B.


“Allen’s company gave a quote that was very fair and within our budget. His employees were really hard workers and knew what they were doing. They did an awesome job, we are very happy with this company. Allen cares about the person or persons he is working for and wants to do a great job. If you need someone to do concrete, I feel confident in referring Allen Winters Concrete.”

“Allen had the lowest bid on the work, and also the most detailed in his bid. He showed up on time and completed the project in two days, doing everything promised on the bid and working with me to insure that everything was A1 in quality. He and all of his crew were very friendly, courteous, and professional. I will use him again when further work is needed and I recommend him highly.”

“Allen Winters built a beautiful new front entry to my house. They eliminated steps and allowed for wheel chair accessibility. Allen’s many years of experience enable him to provide a lot of advice on how to best solve several complex problems to create an entry that did not have a “wheel chair ramp” look to it. His multiple contractors licenses also helped address draining, irrigation, re-piping, etc. I would recommend him again.”

Roger W.


“I am very pleased with the finished product! I have to say that overall, he and his team are the best “contractor experience” one could hope for. They showed up when they said they would and got the job done while I was at mine. It was nice to come home to see the daily progress that they had made, without having to worry about anything. NICE JOB!”
