New home construction, ADU projects, and older homes with failing foundations all need the same thing: a properly designed and poured base that handles Novato's soil and seismic requirements from day one.

Foundation installation in Novato covers excavation, forming, placement of steel reinforcement and anchor bolts, concrete pouring, and curing under inspection - most straightforward residential projects run one to three weeks from the first day of digging to a foundation ready for framing.
The most common type installed in Northern California is a perimeter foundation, also called a stem wall, which creates a raised crawl space beneath the house and keeps the living area off the ground. This design allows access to plumbing and wiring underneath and makes repairs easier down the road. Novato's older neighborhoods have a lot of homes from the 1950s through 1970s whose foundations were not built to current seismic or drainage standards, and many are now being replaced as part of larger remodels or ADU additions. If you are adding a backyard unit or extending your home, we can coordinate foundation work with concrete parking lot building or other flatwork to match your site plan.
The American Concrete Institute sets the national standards for how concrete foundations are designed and built in seismic zones. California Geological Survey publishes the soil and seismic hazard maps that inform how foundations in Marin County should be designed - we work to those standards on every project.
If doors or windows that used to open and close smoothly have started sticking, jamming, or leaving visible gaps at the corners, the frame of your house may be shifting. This kind of movement is often caused by foundation settlement or soil movement underneath. In Novato's clay-heavy soils, this symptom tends to get worse after a wet winter.
Diagonal cracks running from the corners of door frames or windows toward the ceiling are one of the clearest signs that your foundation is moving unevenly. Hairline cracks in drywall are common and usually harmless, but cracks wider than a quarter-inch or cracks that grow over time deserve a professional look.
If you place a marble on your floor and it rolls on its own, or if you notice a visible slope when you walk through a room, the foundation beneath that area may have settled or shifted. This is especially common in older Novato homes built in the 1950s and 1960s. An uneven floor is not just uncomfortable - it is a signal that the structure above may be under stress.
If water pools against the base of your home after a rainstorm and does not drain away within a day or two, that moisture is working its way into the soil around your foundation. Over time, repeated wetting and drying cycles can erode or destabilize the ground. Novato's wet winters make this a real risk for older properties.
Every foundation installation starts with excavation - digging out the perimeter where the foundation will sit and removing any existing material or debris. We then build the forms that give the concrete its shape, place the steel reinforcement and anchor bolts according to the engineer's drawings, and coordinate the required city inspection before the concrete truck arrives. After the pour, we manage the curing process and handle the final inspection so the permit closes out cleanly. We also work with structural engineers to produce the stamped drawings the City of Novato requires - in some cases a geotechnical soil report is required too, and we can coordinate that step as well. If your project also needs related concrete work, we handle slab foundation building and can scope the full foundation package under a single contract.
Foundation replacement is more involved than new construction because the existing house has to be supported while the old foundation is removed. This work is common in Novato's older neighborhoods, where many homes from the 1950s and 1960s have undersized footings, no anchor bolts, or drainage problems that were never addressed when the home was built. We will walk you through what to expect - this is not a surprise-free project, but it is manageable with the right planning.
Best for homeowners building a new home, ADU, or addition from the ground up on bare land or a cleared lot.
Best for homeowners with an existing house on a failing or substandard foundation that needs to be rebuilt while the house is supported.
Best for homeowners adding a room, garage, or backyard ADU who need a new perimeter foundation tied into the existing structure.
Novato's soils range from stable alluvial fill in the flatlands to expansive clay-rich soils in hillside neighborhoods. Expansive clay absorbs water and swells in winter, then shrinks and cracks in the dry summer months - a cycle that puts constant stress on foundations. On top of that, Novato sits near the Rodgers Creek and Hayward fault systems, which means California's building code requires specific earthquake-resistant features like anchor bolts that tie the house frame to the foundation and additional steel reinforcement. These are not optional add-ons - they are part of what gets inspected before the concrete is poured. We have worked in Novato long enough to know which neighborhoods have the most challenging soil conditions and how the City's permit process works - both matter when you are planning a foundation project.
Novato's Mediterranean climate means the ground is saturated from roughly November through March and bone-dry the rest of the year. Pouring concrete in very wet conditions can compromise quality, and excavating in saturated soil is harder and more expensive. Most contractors prefer to schedule foundation work in the spring or fall when conditions are more predictable. We also serve homeowners in San Rafael and across Marin County, where many of the same soil and climate conditions apply.
We respond within 1 business day to schedule a free on-site visit. We will ask the size of your home, whether this is new construction or a replacement, and whether you have had any soil or engineering work done.
We assess the site conditions - soil type, drainage, and access for equipment. You should expect a written estimate that breaks down the major cost categories, not just a single number. We will also let you know if a soil report is required.
We handle the permit application with the City of Novato Building Division and coordinate the engineering drawings. Plan review typically takes a few weeks. Once approved, we begin excavating and set up the forms and steel reinforcement.
A city inspector visits the site to verify steel placement before the concrete truck arrives. Once the pour is complete, we manage curing and pass the final inspection. You get the approved permit documents to keep in your records.
Free on-site estimate. We visit your property, assess soil and access, and give you a written quote with no obligation. Permit coordination handled by us.
(628) 348-0057We have installed foundations across Novato and Marin County and know where expansive clay conditions show up and which sites have drainage challenges. That local experience shapes how we design every project from the start - not just the steel schedule, but the footing depth and drainage layout.
We work with licensed structural engineers to produce the stamped drawings the City of Novato requires, apply for your building permit, and schedule every required inspection. You never have to chase city staff or wonder if the paperwork is in order - we close out the permit and give you the approved documents at the end.
Novato's proximity to the Rodgers Creek fault means seismic detailing is required by code on every foundation here. We do not treat it as an add-on - it is built into every estimate, every drawing, and every pour we do in this area.
Novato's rainy season runs November through March. We plan foundation work in the dry season - spring or fall - so you are not excavating in saturated ground or pouring in active rain. Weather contingencies are built into the schedule so your project finishes on time.
Every one of these points connects directly to the specific conditions homeowners in Novato face. Expansive soils, seismic requirements, a multi-week permit process, and seasonal weather are not abstract - they are the everyday reality of installing a foundation in Marin County, and we are set up to handle all of it.
