Mud, clay soil, and rainy winters turn most San Anselmo backyards into wasted space. A properly built concrete patio gives you a level, draining surface outside your door for all twelve months.
Concrete patio construction in San Anselmo starts with excavating the area, laying a compacted gravel base, pouring concrete inside a wood form, and finishing the surface to drain water away from your home - most residential patios take one to two days of active work, then about a month of curing before you put furniture on them.
A lot of San Anselmo backyards go unused for half the year because the ground turns to mud the moment it rains. Others have older concrete or brick patios that have cracked, shifted, or lost their drainage slope entirely. Either way, the fix is the same: a properly prepared surface that stays level, sheds water correctly, and does not require constant patching or maintenance.
If you are also considering a water feature or outdoor entertainment area, our concrete pool decks service uses the same base preparation and drainage principles and can be coordinated with a patio build to create a unified outdoor space.
If your backyard is mostly lawn, gravel, or sloped ground, you likely lose it as functional space for much of the year. Many San Anselmo homeowners find that adding a patio transforms a yard they rarely used into one they step into every evening. A level surface changes how you actually live in your home.
San Anselmo's wet winters test low spots near your foundation every year. Standing water after a storm means drainage is not working right - and a properly graded patio redirects that water away from your home. Left alone, persistent moisture near a foundation leads to much more expensive problems over time.
If your current concrete or brick patio has shifted, cracked significantly, or developed edges that catch your feet, it is past the point of patching. Uneven surfaces are a trip hazard for children and older family members. In many cases, replacing the old surface is more cost-effective than repeated repairs that keep failing.
Parts of San Anselmo sit on clay-heavy ground that becomes soft and slippery when saturated. If your backyard is unusable for three to four months every winter, a concrete patio over a properly prepared base solves that permanently. You get your outdoor space back for all twelve months, not just the dry ones.
Every patio project starts with a site visit. We measure the space, check access for equipment, evaluate soil conditions, and assess how the yard drains. On sloped or clay-heavy lots - both common in San Anselmo - we adjust the base depth and drainage design before a single form goes in. That prep work is what separates a patio that looks good for years from one that starts cracking and heaving after the first wet winter.
Finish options range from plain gray concrete to broom texture, exposed aggregate, and stamped patterns. Stamped concrete is a popular choice for San Anselmo homeowners who want the look of stone or brick without the ongoing maintenance of individual pavers. We also handle color mixing if you want the patio to complement your home's exterior rather than blend into the background.
For homeowners planning an outdoor space that includes both a patio and a decorative finish, our stamped concrete services and concrete pool decks can be designed as a single system so the surfaces connect cleanly in material and drainage.
Suits homeowners who want a clean, durable outdoor surface at a practical price - the most common choice in San Anselmo.
Suits homeowners who want a decorative surface that mimics stone or brick without ongoing maintenance of individual pavers.
Suits craftsman and ranch-style homes where a textured, natural-looking surface complements the architecture.
Suits sloped or clay-heavy lots where directing water away from the foundation is as important as the surface finish.
Marin County's clay soils expand when wet and shrink when dry, and that cycle puts real stress on concrete over time. In San Anselmo specifically, many lots also have limited truck access - gates that are too narrow, steep grades, or mature trees close to the work area. When a concrete truck cannot reach the pour site directly, contractors use wheelbarrows or a pump, which adds labor time. Getting an accurate estimate requires that the contractor actually sees your yard first.
The town also participates in Marin County's stormwater program, which limits how much hard surface you can add without addressing drainage. We design patios to meet those requirements - directing runoff to planted areas or the street rather than pooling near your foundation or a neighbor's yard. Homeowners in Fairfax and Mill Valley face the same county rules, and we handle those projects by the same standard.
Timing matters here. Concrete pours need dry, stable conditions, and San Anselmo's rainy season makes November through March a poor window for new patio work. If you want your patio ready for summer, reaching out in February or March gives you the best shot at getting on the schedule before the dry-season rush fills up available dates.
We come to your property, measure the space, look at access conditions and soil, and talk through finish options. You receive a written estimate within one business day. No phone quotes - seeing the yard is the only way to price it accurately.
For most new patios in San Anselmo, we apply for the building permit through the Town's Community Development Department before work begins. This adds one to two weeks to the timeline, but you do not need to visit the permit office yourself - we handle all of it.
The crew excavates to the correct depth, compacts the soil, and lays a gravel base. On clay-heavy lots, we go deeper and adjust the base to account for seasonal soil movement. This is the foundation your patio sits on for the next 30 to 50 years.
Concrete is poured and finished in a single day, including your chosen surface texture. The patio is walkable in 24 to 48 hours, but heavy furniture and planters should stay off for at least a month. We coordinate the town inspection as part of the permitted close-out.
We visit your property before we quote - so you get a number that reflects your actual yard, not a generic estimate. Marin dry-season schedules fill up fast. Call or fill out the form and we will follow up within one business day.

A concrete patio is a long-term investment in how you use your home. Built right, with proper site prep and drainage, it will still look and function correctly decades from now. The Portland Cement Association recommends a minimum 28-day cure before heavy loading - we explain exactly what that means for your timeline so there are no surprises on when you can use your new space. And before you hire anyone, take 30 seconds to verify their California contractor's license on the CSLB website.
