A cracked, sunken, or gravel driveway affects your home every day. We build concrete driveways in Windsor that handle Sonoma County winters, local clay soils, and decades of daily use.

Concrete driveway building in Windsor involves excavating the existing surface, grading and compacting the base, setting forms, pouring ready-mixed concrete, finishing the surface, and allowing the slab to cure - most residential jobs take one to three days of active work, plus about a week before you can drive on it.
Windsor homeowners deal with a specific challenge that most online guides overlook: the clay-heavy soils across Sonoma County expand in winter rain and shrink in summer heat. That seasonal movement is the main reason driveways crack in this area. Getting the base preparation right matters more here than in most parts of the country. If your current driveway is cracked, sunken, or draining poorly toward your garage, those are signs the original base work was not done properly - not just that the surface has aged.
Many Windsor properties benefit from pairing a new driveway with concrete patio construction at the same time, since coordinating the two projects in a single mobilization saves both time and money on site prep.
Surface cracks wider than a quarter-inch, or sections that have dropped noticeably, signal that the base beneath has shifted. Patching the surface without fixing the cause is a short-term fix. Left unaddressed, the problem spreads and the repair cost grows.
If water collects at the low end of your driveway or runs toward your garage, the slope is wrong or the surface has shifted. In Windsor's rainy season, that pooling puts constant pressure on your garage door threshold and foundation edge - problems that get worse with every wet winter.
Older Windsor homes, especially those built before the 1990s growth wave, sometimes have unpaved or asphalt parking areas. Gravel turns to mud during wet season. Worn asphalt develops ruts and potholes. A concrete replacement eliminates the ongoing maintenance and mess.
If you are adding an accessory dwelling unit, converting a garage, or need space for a second vehicle, a new or expanded driveway is often part of the project. Getting the concrete work done during the same construction phase saves money and avoids disturbing finished surfaces later.
Every driveway project starts with proper site preparation - excavating the existing surface, removing soft soil, adding and compacting a gravel base, and setting forms to the correct grade. That foundation work is what separates a driveway that holds up for 30 years from one that cracks within five. From there, we pour ready-mixed concrete, finish the surface to your specification, cut control joints at the right intervals, and manage the permit and inspection process from start to finish.
We also handle related flatwork that homeowners often combine with a new driveway. If your project includes walkways to the front door or along the side of the house, concrete sidewalk building can be completed in the same mobilization so you avoid double site costs and get a uniform finish across both surfaces.
Full build from excavation to finished slab - suits homes with gravel, asphalt, or no driveway at all.
Tear out of the existing slab and full pour - the right choice when the old surface is too far gone to patch.
Expanding an existing driveway for a second vehicle or wider turning radius - suits homes where the original pour was undersized.
Broom, brushed, exposed aggregate, or stamped finishes - suits homeowners who want curb appeal to match Windsor's wine country neighborhoods.
Windsor sits in Sonoma County's inland valley, and the ground here behaves differently than in most California cities. The clay-heavy soils that underlie much of the Santa Rosa Plain expand when they absorb winter rain and shrink again during the long dry summers. A driveway poured over clay without proper base preparation will shift, heave, and crack - not because of freeze-thaw stress (which is rare here), but because the ground beneath it is moving. Getting the excavation depth, gravel base, and joint placement right for local conditions is the foundation of durable work in this area. The dry season from late spring through early fall is the best window for a new pour, since rain on fresh concrete during Windsor's wet winters can ruin the surface finish and weaken the slab before it fully cures.
Many Windsor homes were built during the rapid growth of the 1980s and 1990s, which means a significant number of driveways in neighborhoods like those near central Windsor are now reaching the end of their original service life all at once. We also serve homeowners throughout Santa Rosa and the surrounding Sonoma County communities where the same soil and weather conditions apply.
