Homeowners who love the warmth of real wood siding but not the upkeep of it keep landing on the same product: LP SmartSide. It is engineered wood — the look and texture of a genuine wood grain, built to shrug off the moisture and pests that make solid cedar or redwood such a maintenance commitment. On Cotati's mix of older cottages and newer tract homes, that combination hits a real sweet spot. Bay Area Siding Company installs LP SmartSide across Cotati and the rest of Sonoma County; we are a Larkspur-based (Marin) siding and window contractor.

LP SmartSide is built from wood strands bound with resins and treated through LP's SmartGuard process — a treatment carried through the board that adds resistance to fungal decay and termites, the two things that historically shortened the life of natural wood siding. The result is a board that keeps a convincing wood grain and takes a range of profiles — lap, panel, trim, and shake — while being lighter and easier to work than fiber cement, and notably more impact-resistant. A stray branch or a ladder knock that might chip a cement board is far less likely to damage SmartSide. LP backs the product with a well-regarded, long limited warranty; the specific terms are worth confirming at spec time rather than quoting here.
Cotati's town center is built around a hexagonal plaza ringed by older cottages and early-subdivision homes, many of which wear — or once wore — wood siding that suits their era. SmartSide lets you keep that warm, wood-sided character without signing up for the repaint-and-repair cycle that real wood demands. On the postwar and newer tracts along the US 101 corridor, it is a warmer, more textured alternative to vinyl or aged hardboard. The town sits on the flat valley floor at the edge of the Laguna de Santa Rosa basin, and gets a cooler, marine-influenced climate through the Petaluma Gap — wet winters and mild, bright summers. Engineered wood handles that moisture far better than solid wood, provided one thing holds true: it has to be kept painted.
SmartSide is low-maintenance compared to real wood, but it is not no-maintenance the way vinyl or fiber cement's factory finish can be. It is a wood-based product with a paintable surface, and that finish is part of what protects it. Over the years it will want repainting — less often than solid cedar, but it is a real line item to plan for. Cut edges and penetrations have to be sealed properly at install, and the board relies on a sound coat of paint to keep the wet-winter moisture out over the long run. We prime and detail it correctly at install, and we are straight with homeowners that choosing SmartSide means committing to a repaint down the road. If a genuinely paint-free exterior is the priority, fiber cement or vinyl is the better match.

SmartSide is a wood-based product and is combustible, which is worth naming because it steers the choice on fire-hazard parcels. In Cotati that is usually not a constraint: most of the town sits on flat valley-floor ground that is generally not mapped as a Very High Fire Hazard Severity Zone the way foothill and ridge parcels elsewhere in Sonoma County can be, so engineered wood is a reasonable choice for most homes here. Designations are parcel-specific and maps change, so if your address is a question we confirm it before speccing — and where a parcel does carry a fire-hazard designation, we would point you toward noncombustible fiber cement instead.
Re-siding in Cotati is a permitted alteration through the City of Cotati Community Development Department, Building Division via the Cloudpermit portal, and we handle it. On the install we remove the old cladding down to the sheathing and substrate so the water-resistive barrier and the flashing can be inspected and corrected before the new siding goes up, then hang and detail the SmartSide to LP's spec — priming, sealing cut edges, and finishing so the board is protected from day one. We price after we measure. The drivers are the home's size and stories, the profile and finish you choose, whether you go with factory-primed or a full finish coat, how much substrate or flashing repair surfaces at tear-off, and the trim and window detailing involved.
How is LP SmartSide different from real wood siding? It is engineered from treated wood strands rather than solid lumber, which makes it far more resistant to rot and termites and more dimensionally stable, while keeping a convincing wood grain. It is lighter and more impact-resistant than fiber cement, too. The trade-off is that, like wood, it needs periodic repainting.
Does SmartSide hold up in Cotati's wet winters? Yes, when it is installed and maintained correctly. The SmartGuard treatment and proper edge-sealing handle the moisture, but the paint finish is part of the protection — keeping it painted is what makes the board last through repeated wet seasons.
Is SmartSide a good choice near the plaza's older homes? Often, yes. It lets you keep the warm, wood-sided character of an older Cotati cottage without the full maintenance load of solid cedar or redwood. On a fire-hazard parcel we would steer you to fiber cement instead, but most valley-floor lots are not so designated.
Do I need a permit for a SmartSide re-side? Yes. It is a permitted alteration through the City of Cotati Building Division via Cloudpermit. We manage the permitting and inspections.
