Learn MoreReach out by phone or the contact form. Tell us what you need - a driveway, patio, foundation, or something else. We ask a few quick questions and schedule a time to come see your property. You can usually expect to hear back within 1 business day.
We visit your property, take measurements, and look at the ground conditions. You get a written estimate that covers materials, prep work, and labor - no surprises. We also handle any permit questions so you know exactly what the full process involves before you commit.
Once you approve the estimate, we schedule the project, pull any required permits, and show up on time. Our crew handles prep, the pour, finishing, and cleanup. When we leave, the job is done - and you have a concrete surface built to last in Sonoma County's climate.
We hold a California state contractor's license, verifiable through the CSLB, and carry general liability and workers' comp on every project. No license means no accountability - you should always verify before anyone pours a single yard of concrete on your property.
We have worked in Sonoma County's clay soils, handled the permit process with Windsor's building department, and know what the wet-dry cycle does to a slab built on a weak base. That local knowledge is what you are paying for - not just concrete.
We come to your property, look at the ground, take measurements, and give you a written quote. Nothing is added after you sign. If the scope changes, we talk about it before we act on it - that is how the relationship stays simple.
Concrete work near the street, attached to your home, or on a new foundation often requires a permit in Windsor. We pull the approvals, schedule any required inspections, and close out the permit - so the work is on record and your home sale won't hit a snag over unpermitted flatwork.

"They replaced our cracked driveway before the rainy season, which was exactly what we needed. The crew finished in two days and the slab looks solid - no low spots, clean edges. Six months in and not a crack to report."
Robert T., Windsor
Concrete driveway building
"We wanted a stamped patio that matched the stone look of our house. They walked us through pattern options, pulled the permit, and had the whole thing done in three days. The finished surface looks better than we imagined."
Maria C., Santa Rosa
Stamped concrete services
"We needed a slab foundation for a new garage and weren't sure about the soil on our property. They explained the base prep process before we even signed anything. The pour went exactly as scheduled and passed inspection without issues."

The main cause isn't freeze-thaw cycles - it's the clay soil. Sonoma County's clay-heavy ground expands in wet winters and shrinks in dry summers, stressing any slab on top. Proper base prep and control joints are the fix.
Late spring through early fall is the most reliable window. Windsor's rainy season runs November through March, and wet concrete is ruined concrete. Summer heat is manageable with curing compounds and early-morning pours.
Poured concrete handles Sonoma County's clay soils better than pavers because it's one solid slab. Individual pavers shift as the ground moves, creating uneven surfaces and weed gaps. Concrete stays level with a well-built base.
UV exposure does fade color over time. Windsor's long, sunny summers accelerate fading compared to cloudier climates. UV-resistant sealers and resealing every two to three years keeps stamped surfaces looking sharp.
Yes. Concrete is non-combustible and won't ignite from embers. In Sonoma County, where wildfire smoke and ember events are seasonal realities, a concrete patio or pool deck removes a real ignition risk. Learn more from FEMA's wildfire preparedness resources.
California requires contractors to hold a state license issued by the Contractors State License Board. Verify any license at cslb.ca.gov - it takes two minutes and tells you if the license is active, bonded, and in good standing.

Standard residential sidewalks and patios often don't require steel rebar, but driveways, foundations, and anything that will carry vehicle weight almost always do. Ask your contractor what reinforcement is in the quote and why.
Rain on fresh concrete is one of the more serious problems that can happen during a project. It dilutes the surface, creates a weak top layer, and can ruin the finish entirely. A good crew checks the forecast and won't pour if rain is likely in the first 24 to 48 hours.
Low bids usually cut base prep, skip permits, or use thinner concrete than the job calls for. Always ask each contractor to itemize the quote so you can see exactly what is and isn't included before you compare numbers.
The American Society of Concrete Contractors publishes best practice guides for residential flatwork that are worth a read if you want to understand what quality concrete work actually involves. When you're ready to talk through your project, call us at (707) 687-4808.
Windsor is a town of about 26,000 in Sonoma County, sitting about 9 miles north of Santa Rosa in the Russian River Valley corridor. Much of the housing stock was built during the rapid growth of the 1980s and 1990s - which means a large share of driveways, patios, and walkways across town are now 30 to 40 years old and showing it. The Town of Windsor has a well-kept downtown centered on the Windsor Town Green, with residential neighborhoods spread out along the 101 corridor and toward the vineyard edges of town where lot sizes are larger and properties often include long driveways or outbuildings.
The clay-heavy soils across Sonoma County are the main reason concrete work in this area requires more care than in many other parts of the country. That soil swells with winter rain and shrinks in the summer heat, which stresses slabs built on an inadequate base. Combine that with Windsor's concentrated wet winters and bone-dry summers, and you have conditions that expose every shortcut a contractor took on base prep - usually within the first few rainy seasons. At Meridian Windsor Concrete Company, every project in Windsor accounts for local soil conditions from the first excavation cut, so the concrete we pour is built for the ground it actually sits on.
