Serving Altadena, CA and surrounding areas. (323) 329-3072
Cracked sidewalks and undefined landscape edges make your property look neglected. We install clean, lasting concrete that holds up through Altadena seasons.
Concrete curbing and sidewalks in Altadena means forming, pouring, and finishing concrete into clean borders and walking surfaces, and most residential jobs are completed in one to two days of active work with a few days needed for the surface to cure before foot traffic resumes.
A lot of Altadena homes were built in the 1920s through 1960s, and the concrete work around them has been moving with the clay soil ever since. Heaved sections and undefined landscape edges are common. Whether you want a fresh front walkway, a clean border between your lawn and driveway, or both, we size and prep the job to the actual conditions on your property. If your project also involves other hardscape work, pairing it with grading and excavation at the same time saves money and keeps everything level.
When a section of sidewalk rises or tilts, Altadena's clay soil has shifted beneath it. The gap between slabs catches feet and wheels. Once a slab has moved significantly, patching rarely holds because the ground movement continues.
If your lawn creeps into the driveway or mulch washes onto the walkway after every rain, there is no defined border holding things in place. Concrete curbing provides a permanent edge that does not wash away or need to be reset each year.
Small surface checks are normal, but cracks that run across the full width of a slab mean the concrete has lost structural integrity. Water gets into those gaps, the soil below erodes, and the slab sinks further. Replacement is more effective than repeated patching at this stage.
When the top layer of concrete flakes off and the surface feels rough and pitted, the material has deteriorated. In Altadena's dry summers the sun works on older concrete year after year. A spalling surface is both an eyesore and a slip hazard - it will not improve on its own.
We handle new sidewalk installation, full concrete replacement, and decorative curbing for Altadena residential and commercial properties. When old concrete needs to come out first, we break it out and haul it away before grading the base. Every pour is sloped correctly for drainage - a detail that matters in a foothill community that gets heavy rain in short bursts. For properties that also need a re-established grade or drainage channel, we coordinate that work alongside the concrete so you have one crew, one timeline, and one finished result.
Curbing choices include standard straight-edge borders, rolled curbs, and decorative profiles. For sidewalks, finish options include broom texture, exposed aggregate, and stamped patterns. If your project sits near the public right-of-way, drainage solutions are often part of the same scope - we assess both at the same time so nothing is missed. We handle LA County permit applications for work that touches the county right-of-way.
Best for properties with no existing walkway or for homeowners replacing a full run of cracked or heaved slabs.
Best for homeowners who want a clean, permanent border between lawn, garden beds, or driveways.
Best for front entries and high-visibility areas where broom texture, exposed aggregate, or stamped patterns add character.
Best for properties where isolated sections have heaved or cracked while the rest of the walkway is still sound.
Altadena's clay-heavy soils are the main reason concrete work here needs to be done differently from the flatlands. The soil expands with every winter rain and contracts through the long dry summer - that movement is what pushes slabs out of level and opens cracks over time. Getting the base right before the pour, and cutting control joints at the correct spacing, is the difference between concrete that lasts 25 to 30 years and concrete that fails in five. Properties near the foothills also deal with runoff after heavy rain events, so slope and drainage built into the pour protect your landscaping and foundation.
Because Altadena is an unincorporated community under LA County, the permit rules for work near the street are specific to the county process - not a city process. We have pulled those permits before and handle the paperwork so you are not chasing approvals mid-project. We serve concrete curbing and sidewalk customers across the area, including Pasadena and La Canada Flintridge, where similar soil and right-of-way conditions apply.
Describe the project - length of sidewalk, whether old concrete needs removing, any finish preferences. We respond within one business day and schedule a site visit before quoting anything.
We walk the area, check the slope and soil, and confirm whether the project touches the county right-of-way. If a permit is needed, we explain the process and handle the application. No charge for the visit.
Old concrete is broken out and hauled away if needed. The crew grades and compacts the base material - the most important step in Altadena's clay-soil environment - then sets forms to define shape and slope.
Concrete is poured, leveled, and finished to your chosen texture. Control joints are cut at the right spacing. The surface needs three to five days before foot traffic and at least a week before vehicles.
We handle the site visit, base prep, and LA County permits. No pressure - just a clear quote.
(323) 329-3072Altadena sits on expansive clay that swells in winter and shrinks in summer - the main reason local concrete cracks faster than the textbooks say it should. We compact the base and cut control joints at the right spacing so movement happens where it is planned, not randomly through the slab. USGS research on expansive soils explains why base preparation matters as much as the concrete mix itself.
Because Altadena is unincorporated, sidewalk work near the street falls under county permit rules - not a city process. We have pulled those permits before and handle the paperwork so the project does not stall mid-job.
Old concrete that needs to come out does not become your problem to deal with. We break it out, load it, and haul it away as part of the job. You see the finished result without managing disposal.
California requires a state license for concrete and paving work. Our license is active and verifiable at cslb.ca.gov. Ask for the number before signing anything with any contractor - it takes two minutes to verify.
Every concrete job we take on starts with a site walk and an honest assessment of the base. If the soil or drainage conditions need attention before the pour, we say so - because concrete that starts on a bad base does not stay flat for long in Altadena.
Grind down a deteriorated asphalt surface to the correct depth before a fresh overlay - the right step before concrete transitions are set.
