Meridian Windsor Concrete Company is a concrete contractor serving Sebastopol, CA with decorative concrete, driveways, patios, retaining walls, and foundations. We have been working in Sebastopol and western Sonoma County since 2019, and we understand the large lots, older wood-frame homes, coastal fog, and clay soils that make concrete work here different from other parts of the county.

Sebastopol homeowners tend to value craft and character in their properties, and decorative concrete delivers a finished surface that fits that sensibility - stamped patterns, exposed aggregate, and color finishes that hold up in the wet coastal climate without the ongoing maintenance that wood or loose materials require. Explore our decorative concrete services and see what is possible on a Sebastopol property.
Long driveways are common on Sebastopol's larger lots, and many of them are aging gravel, cracked asphalt, or decades-old poured concrete that no longer drains or holds up well. We build concrete driveways sized for Sebastopol's property types, with base prep that handles clay soil movement and wet winters without crumbling inside of a decade.
Properties near the Laguna de Santa Rosa and in lower-lying areas around town deal with drainage and soil saturation every winter. A concrete retaining wall stabilizes sloped sections, redirects runoff, and creates level usable ground on lots that would otherwise lose soil every rainy season.
Sebastopol summers are mild and foggy enough to make outdoor living comfortable well into the evening, and a concrete patio is one of the most durable outdoor surfaces for this climate. We build patios that drain away from the structure, resist the freeze-thaw cycles of winter nights, and hold their finish even in high-moisture conditions.
Older Sebastopol homes often have walkways buckled by tree roots or cracked by decades of clay soil movement. Repair or replacement work that touches the public right-of-way requires city approval, and the standards differ from what the county requires. We handle the permit process through the City of Sebastopol so the work is done correctly from the start.
Sebastopol's large lots often have older outbuildings, barns, or detached garages left over from the area's farming history that need new foundations or replacement slabs. We pour slab foundations with the reinforcement and joint design suited to clay soils and high-moisture conditions so new structures start on solid, stable ground.
Sebastopol is the only incorporated city in Sonoma County west of Highway 101, which puts it squarely in the zone where coastal fog rolls in regularly from the Pacific. That fog keeps humidity high year-round - even summer mornings stay damp well after the sun is up. Wood fences, decks, and driveways that are not sealed and maintained correctly absorb that moisture steadily, and concrete surfaces on clay soil get the added stress of the ground expanding and contracting with every wet-dry cycle. The result is a faster rate of cracking, heaving, and surface wear than homeowners who moved here from drier inland areas might expect.
Sebastopol's housing stock skews older, with many mid-20th-century homes and some that pre-date World War II. A lot of the concrete flatwork on these properties has never been replaced and is showing its age. The clay-heavy soils common throughout the area also put concrete at risk from seismic activity - the Rogers Creek Fault runs through Sonoma County, and even modest ground movement can crack driveways and walkways that were poured without proper reinforcement. The City of Sebastopol handles its own building permits separately from the county, so knowing the city's process is important for any concrete work here.
Our crew works throughout Sebastopol regularly, and we understand the local conditions that affect concrete work here. Sebastopol properties tend to have longer driveways and larger footprints than standard suburban lots, which affects how we stage materials and access job sites. We have worked on properties near The Barlow on the north end of downtown, on the residential streets off Gravenstein Highway (Highway 116), and on larger parcels toward the western edge of the city where lot sizes increase and rural conditions apply.
The Laguna de Santa Rosa - one of the largest freshwater wetlands in Northern California - borders the east side of Sebastopol, and properties in that part of town deal with soil saturation and drainage issues that properties further west do not. We factor drainage conditions into our base preparation on every job in this area. We also serve homeowners in Guerneville to the northwest and in Santa Rosa to the east, where the same coastal moisture and clay soil conditions continue.
Call us or submit the contact form with a brief description of what you need. We get back to every inquiry within one business day. You do not need a detailed plan - a general idea of the project and the property address gets things started.
We visit the property, assess the site conditions - including drainage and soil - and measure the area. You receive a written estimate with a clear scope before any work begins. This visit also determines what permits the City of Sebastopol will require for your specific job, so there are no surprises after you sign.
We submit permit applications to the city and schedule your project once approvals come back. Concrete work in Sebastopol is best done in the dry months - roughly May through October - so booking ahead helps lock in your preferred window before the calendar fills.
Active work on most residential projects takes one to three days. The site is cleaned at the end of each day, and we walk you through the finished work before we leave. We provide clear curing guidance so you know exactly when the surface is ready for foot traffic, vehicles, or outdoor furniture.
We serve all of Sebastopol and the surrounding western Sonoma County area. Call or fill out the form and we will respond within one business day.
(707) 687-4808Sebastopol is a small city in western Sonoma County, situated along Gravenstein Highway (Highway 116) between Santa Rosa and the Russian River towns to the west. The city has a strong local identity rooted in its Gravenstein apple growing history - the orchards and farms that once defined the surrounding landscape still dot the hillsides today. Downtown Sebastopol anchors around a compact commercial district that includes The Barlow, a converted mill complex that houses local restaurants, breweries, and artisan shops. The city's character draws longtime residents and newcomers who prefer a quieter, more rural pace than what Santa Rosa and the larger 101 corridor towns offer. You can read more at the Sebastopol Wikipedia article.
Housing in Sebastopol is predominantly single-family, owner-occupied homes with a mix of mid-century construction and some older properties from earlier in the 1900s. Lots in and around the city tend to be larger than in most Sonoma County suburbs - many have long driveways, detached garages, and outbuildings that add up to significant concrete and flatwork needs. The proximity to the Laguna de Santa Rosa on the eastern edge of the city means drainage is a real consideration for properties in that zone. We also serve concrete customers in neighboring Petaluma to the south and in Rohnert Park along the 101 corridor.
