AfterRestoration Company in Cotati, CA
Cotati is a small city with a big geology problem. The adobe clay under most homes here swells and cracks with every wet winter, and the flat Santa Rosa Plain doesn’t drain fast enough to relieve the pressure. That combination means water finds its way into slab foundations, crawl spaces, and drywall in ways that surprise homeowners who’ve lived here for years. If you’re dealing with water, mold, or storm damage in Cotati, call (910) 613-6568 and a live person answers, day or night.
This page is the Cotati overview. The three services we provide here each have their own dedicated page linked just below, with pricing, timelines, and what to expect in this specific city.
Why Cotati Homes Are Different
Cotati sits on the Santa Rosa Plain’s adobe clay soils, directly east of the Laguna de Santa Rosa. The Laguna is a large seasonal wetland that backs up during atmospheric river storms and floods low-lying streets and properties. That’s not a rare event here. It happens multiple times most winters. The water ponds against foundations, sits for days, and works its way into whatever opening the clay has already created.
Most Cotati homes were built between the 1950s and 1970s, slab-on-grade tract houses and small apartment complexes built for the workforce and student population around Sonoma State University. These structures have aging vapor barriers and concrete slabs sitting directly on reactive clay. When the clay gets wet, it heaves. When it dries, it contracts. After forty or fifty cycles, the slab cracks in predictable places and those cracks become permanent water channels.
Old Town Cotati adds another layer. The early-20th-century wood-frame bungalows there were built with balloon framing and minimal insulation, so water that gets behind siding or into a wall cavity travels further and faster than in a modern house. We see this pattern constantly: a homeowner calls about one bad storm, and behind the drywall we find moisture evidence that goes back five or ten winters. The clay crack has been feeding a hidden mold colony for years, and nobody knew until the drywall finally stained.
Cotati gets 28 to 35 inches of rain annually, almost all of it between November and March in intense atmospheric river events. The flat terrain means stormwater drains slowly. That prolonged saturation window, longer than the hillside communities to the east and west, is why category-2 and category-3 water losses are more common here after every major rain. It’s also why mold moves faster in Cotati than most homeowners expect.
Our Main Cotati Services
Water and mold are the two calls we get most from Cotati homeowners, and storm damage runs a close third after every major atmospheric river event. Each service has its own Cotati page with detailed pricing and timelines. Here’s the short version of each.
Water Damage Restoration in Cotati
Cotati water damage is rarely a single event. The adobe clay under slab foundations cracks in the same spots every wet season, creating established entry channels that feed water into the same walls and floors year after year. Our job is to find those channels, not just dry the visible water. We use Dri-Eaz and Phoenix extraction and drying equipment, and we track moisture levels with readings that tell us when the structure is genuinely dry, not just dry on the surface.

Mold Remediation in Cotati
Cotati’s prolonged saturation window after storms means mold has more time to establish than in surrounding hillside communities. The flat terrain holds water against foundations for days, and that moisture wicks into drywall and framing. We find mold colonies behind walls that have been growing for multiple winters, fed by the same crack in the same slab. Remediation here requires finding the moisture source first, then treating the affected materials. Mold Remediation in Cotati
Storm Damage Restoration in Cotati
When the Laguna de Santa Rosa backs up, low-lying parts of Cotati flood, and the water doesn’t leave quickly. Storm damage here means standing water against foundations, saturated crawl spaces, and category-2 or category-3 water losses in homes that have been through this cycle before. We extract first, then stabilize, then dry. The goal is to stop the damage before the clay under the slab starts another heave cycle. Storm Damage Restoration in Cotati

We handle that by giving you a written price before any work starts. It’s a written commitment, printed on the work order, and it doesn’t change once demo begins.
