Serving Corte Madera, CA and surrounding areas. (628) 212-4120
Your sidewalk is cracked, heaved by tree roots, or simply missing. We build and replace concrete sidewalks with the base preparation and root management Marin's soils demand.
Concrete sidewalk building in Corte Madera means removing whatever is there now, preparing a compacted gravel base, and pouring a fresh slab - most residential jobs take one to three days of active work, with roughly a week of curing before the walk is back to regular use.
Most homeowners call us after a sidewalk section has heaved from tree roots, cracked wide enough to become a tripping hazard, or after receiving a notice from the town requiring repairs. In Corte Madera, the combination of mature street trees and clay-heavy soils means root-related heaving is one of the most common sidewalk problems we see - and one that new concrete alone will not fix without first addressing the roots. If you are also looking to improve the driveway at the same time, our concrete driveway building service can be scheduled as part of the same project visit.
We start with a free on-site estimate. We look at the existing surface, check for tree roots or drainage issues, measure the area, and give you a written quote before anything is scheduled.
If part of your sidewalk has lifted on one side, creating a lip or step where slabs meet, that is a tripping hazard and a sign the ground underneath has shifted. In Corte Madera, this is most often caused by tree roots pushing up from below or by clay soil swelling after a wet winter. This kind of unevenness does not fix itself and gets worse each season.
Hairline cracks in concrete are common and usually harmless. But when a crack is wide enough to fit a pencil into - or when you can see one side sitting higher than the other - the structural integrity of the slab is compromised. Water gets into wide cracks, and in Corte Madera's rainy winters that water works under the slab and speeds up the damage.
If the top layer of your sidewalk is breaking apart into small chips or a gritty powder, the surface has deteriorated past the point of patching. This kind of breakdown is a sign the original concrete was mixed or finished poorly. Once it starts, the whole slab typically needs to come out.
The Town of Corte Madera can require homeowners to repair sidewalks that present a tripping hazard, particularly in the public right-of-way. If you have received a notice, or if someone has stumbled on your walk, acting promptly limits your liability and keeps the repair scope manageable before the damage spreads.
Every sidewalk project starts with demolition of the old surface, debris hauling, and proper subgrade work. We compact a gravel base before any concrete is poured - this step is invisible once the job is done, but it determines whether your walk stays level for 30 years or starts shifting within 5. For sections where tree roots caused the original failure, we assess the root situation first and discuss options like root pruning or root barriers before pouring anything new.
We apply a broom finish as the standard surface texture, which provides grip on wet mornings - a practical consideration in a coastal town with regular fog and morning dew. When a homeowner is also addressing stairs from the sidewalk level up to an entry, our concrete steps construction service handles that work alongside the sidewalk in a single visit. For larger paved areas such as front approaches combined with a concrete driveway, we can scope both in one estimate. The Portland Cement Association notes that proper curing - not just the pour itself - is one of the most important factors in long-term slab strength; we do not rush this step.
We pull the required permit through the Town of Corte Madera on every project. Unpermitted sidewalk work - especially work in the public right-of-way - can create real problems when you go to sell the home. We include the permit as a standard part of our process, not an optional add-on.

Corte Madera's tree-lined residential streets are one of the things that make the town attractive - and one of the leading causes of sidewalk damage. Mature roots from street trees push up under slabs over years and decades, creating the raised edges and tilted sections that are a tripping hazard and a liability. When we assess a sidewalk project here, root inspection is part of the process, not an afterthought. Pouring new concrete over an unaddressed root problem just means the slab fails again.
The clay-heavy soils common in Corte Madera - especially in the lower, flatter neighborhoods closer to the bay - swell when wet and shrink when dry. That seasonal movement stresses sidewalk slabs from below, which is why a compacted gravel base is not optional here. Much of the town's housing was built between the 1940s and 1970s, and many original sidewalks from that era are now overdue for replacement. The Bay Area is also one of the most seismically active regions in the country, and well-placed control joints give slabs room to flex slightly without fracturing, as noted by the American Concrete Institute.
We work throughout Marin County, serving homeowners in Larkspur, San Rafael, and Mill Valley alongside our Corte Madera clients. Tree root heaving and clay soil movement affect sidewalks throughout the region, and we bring the same site-specific approach to every job.
We visit in person to look at the existing surface, check for tree roots or drainage problems, and measure the area. You receive a written estimate within one business day that breaks out every cost - demo, base prep, the pour, finishing, and cleanup.
We handle the permit application with the Town of Corte Madera before any work begins. For right-of-way work, this step is mandatory. It adds a few days to the start date and protects you - permitted work is inspected and documented.
The crew removes the old concrete, hauls it away, and excavates and compacts a gravel base. If tree roots are present, we address them before the pour - not after. This step is mostly invisible once the job is done, but it is what the finished walk stands on.
Concrete is poured, broom-finished for grip, and cut with control joints. After roughly a week of curing, the forms come off, the site is cleaned up, and we schedule the town inspection for permitted work. You walk the finished surface with us before we call the job done.
We reply to all inquiries within one business day and provide free on-site estimates with no obligation.
(628) 212-4120Most contractors pour over a root problem because it is faster. We check for root intrusion on every sidewalk job and recommend root pruning or barrier installation when needed. A sidewalk that fails in three years because roots were ignored is not a job we are willing to put our name on.
We pull the required permit through the Town of Corte Madera before any sidewalk work begins - no exceptions. Permitted work is inspected, documented, and clean on your property record, which matters every time someone looks at your home.
We have completed sidewalk projects in more than 40 Corte Madera neighborhoods since 2022. That experience tells us which streets have the most problematic clay, where root heaving is worst, and how deep the base prep needs to be to give a slab a real chance of staying level. We bring that knowledge to every estimate.
Broken concrete rubble has to go somewhere, and some contractors leave that cost out of their initial quote. We include demolition debris removal in every estimate so you know the full price upfront. Material is disposed of at a licensed facility per CalRecycle guidelines.
We treat sidewalk work as a genuine safety project, not just a cosmetic one. A level, properly permitted walk protects you from liability, keeps your property records clean, and gives every person who walks up to your front door a better first impression of your home.
