Windsor Deck & Fence builds custom decks, installs composite and cedar decking, and handles pergola and fence work for homeowners throughout Sonoma. We know the city permit process, the clay soil conditions, and what this climate demands from outdoor structures. Call us and we will respond within one business day.

Sonoma homes range from mid-century ranch houses to historic properties near the plaza, and each one calls for a deck design that fits the architecture and the lot rather than a standard template. Our custom deck design and build service starts with what you want from the space and what the property can support, then builds out from there.
Sonoma's hot, dry summers and wet winters put natural wood through an extreme moisture cycle year after year. Composite decking handles that swing without warping or splitting, and it does not need the annual staining that wood requires - a real time-saver for homeowners who use their Sonoma property part-time.
A pergola turns a Sonoma backyard into an outdoor room that works from spring through fall. The warm evenings in this part of the valley make a shaded outdoor structure genuinely useful most of the year, and the right design can tie into vineyard views without blocking them.
Many Sonoma homes were built in the 1950s through 1970s, and original wood decks from that era often have soft framing, failing ledger boards, and boards that have seen too many seasons. We assess what can be saved and what needs to go, and we give you an honest answer before starting any work.
Covered outdoor spaces extend the usable season in Sonoma by providing shade during the hottest summer months and shelter during winter rain. They also protect the deck surface itself from UV exposure and weather, which significantly extends the life of the wood or composite below.
Sonoma neighborhoods near the plaza tend to have modest lot sizes where a well-built privacy fence makes a real difference in how usable the backyard feels. We use materials suited to the dry summer and wet winter cycle so fences do not twist and separate within the first few years.
Sonoma sits in a high fire hazard severity zone, and after the 2017 Tubbs Fire and the 2020 Glass Fire burned close to or through parts of the valley, many homeowners have been thinking more carefully about the materials they use on the exterior of their homes. Decking materials, roofing vents, and fence construction all factor into how a property handles ember exposure during fire season. A deck builder working in Sonoma should be able to advise on ignition-resistant material options and how they integrate with standard deck construction.
The underlying clay soils in Sonoma Valley add another layer of complexity. Clay expands significantly when wet and shrinks when dry, and that seasonal movement puts stress on concrete footings and foundation elements below deck framing. Decks built on improperly sized or shallow footings in clay soil can go out of level within a few years, pulling the ledger connection away from the house and stressing the entire frame. Addressing the footing design correctly from the start - rather than patching a settling deck later - is the difference between a deck that lasts 20 years and one that needs significant repairs in 5.
Our crew works throughout Sonoma regularly, and we understand the local conditions that affect deck builder work here. Permit applications for Sonoma deck projects go through the City of Sonoma Community Development Department. Properties within the historic overlay district near Sonoma Plaza may have additional design review considerations, and we account for that during the planning phase so there are no permit surprises.
The city covers a relatively compact area, and the housing character shifts noticeably as you move from the older neighborhoods near the plaza toward newer residential streets on the north and east sides of town. We have worked on everything from 1940s bungalows with original framing to more recent construction on the valley edges. The Sonoma Valley wine country corridor - the roads lined with vineyards heading south toward the Sonoma-Carneros area - includes some of the larger residential parcels where deck and outdoor structure projects tend to be more substantial in scope.
We also regularly serve homeowners in nearby Kenwood up the valley, and in Petaluma to the south. If you have projects at multiple properties, we can coordinate scheduling efficiently across the area.
Contact us by phone or through our online form and we will reply within one business day. Share the address, the project type, and your rough timeline - we will ask about the property and any existing structures before we schedule a site visit.
We come to the property, assess what is there - including soil conditions, access, and existing framing if it is a repair - and provide a written estimate. You will know what the project costs before any work begins, and we will flag if city permit fees factor in.
For permitted projects, we handle the City of Sonoma application and coordinate the required inspections. We manage the review timeline so the build schedule is realistic from the start, and we keep you updated if city review runs longer than the standard window.
We complete the work, clear the site, and walk through the finished project with you before we leave. Any questions about maintenance, material care, or follow-up work get answered at that walkthrough so you know exactly what you have.
We serve homeowners throughout the city of Sonoma and the surrounding valley. Reach out by phone or online form and we will get back to you within one business day with a straightforward answer on next steps.
(707) 687-4980Sonoma is a small city of roughly 11,000 people at the heart of Sonoma Valley wine country, about 45 miles north of San Francisco. The city is best known for Sonoma Plaza - the largest historic town square in California - surrounded by tasting rooms, restaurants, and the old city hall. The residential neighborhoods immediately surrounding the plaza include some of the oldest homes in the city, many dating to the mid-20th century or earlier, with wood-frame construction, stucco exteriors, and mature landscaping. Farther from the plaza, the housing transitions to ranch-style homes built in the 1960s and 1970s, with more recent development along the outer edges of the city.
Sonoma State Historic Park, which preserves Mission San Francisco Solano and the Sonoma Barracks right in the center of town, gives the city an unusually dense historic character for its size. Owner-occupancy rates are relatively high here, and many residents treat their homes as long-term investments rather than just places to live - that shows up in the willingness to do outdoor projects right the first time. Homeowners in the northern end of Sonoma Valley, toward Kenwood, will find that we serve that community as well, and our work throughout the valley means we are already familiar with the properties and conditions across the whole region.
