Serrato Builders is Altadena's trusted C-8 licensed concrete contractor. We provide expert concrete driveways, stamped patios, structural foundations, and concrete replacement throughout Altadena. Licensed, bonded, insured — we pull permits and deliver quality craftsmanship at the foothills of the San Gabriels.
Altadena sits beautifully at the base of the San Gabriel Mountains — an unincorporated community with a rich architectural heritage, Craftsman homes, mid-century gems, and hillside properties with breathtaking views. Serrato Builders, as a C-8 licensed concrete contractor (License #1115625), has completed projects throughout Altadena's 91001 zip code. From the historic estates near Christmas Tree Lane to the hillside homes along the mountain front, we deliver concrete that respects Altadena's character.
Altadena properties present unique challenges: hillside terrain with decomposed granite soils, wildfire zone building requirements, and LA County (not City) permit processes. Our team understands these conditions intimately. Hillside foundations with caissons and grade beams, reinforced retaining walls, and drainage-integrated hardscape are all part of our regular work in Altadena.
Altadena residents value craftsmanship, character, and contractors who understand the foothill environment. Here's why they trust us:
Altadena's hillside properties offer stunning mountain and city views — but require serious engineering. We pour hillside foundations with caissons and grade beams, install reinforced retaining walls that manage decomposed granite soil pressure, and integrate drainage systems that protect against the heavy rains that can hit the foothills. This is specialized work, and we have the experience Altadena demands.
Altadena driveways range from long, winding approaches to hillside homes to classic front drives on historic properties. We handle complete driveway replacement with proper grading, reinforcement, and finishing. Options include broom finish, stamped concrete, exposed aggregate, and colored concrete — all with the proper drainage that Altadena's terrain requires.
We serve every Altadena neighborhood — from the historic district near Christmas Tree Lane to the hillside communities along the mountain front, the neighborhoods near Farnsworth Park, and all properties throughout the 91001 zip code. Wherever you are in Altadena, we're your local concrete contractor.
