We started in the trades — concrete and framing, the work that either holds or doesn't — and built Guillen Construction into a licensed general contracting company the same way you build anything that lasts: one straight job at a time.
Guillen Construction Inc is family-owned and based in Mission Hills, in the San Fernando Valley. The people who run this company come off the tools, not out of a marketing department: we poured foundations, framed houses, and hung drywall for other builders before we ever put our own name on a truck. That history is why our crews self-perform the core trades instead of brokering every scope to the lowest bidder — and why our schedules hold.
Construction has a trust problem, and we understand why. Our answer is boring and effective: be licensed and insured, put everything in writing, follow California's payment rules, pull real permits, show up when we said, and tell you the truth even when it costs us the job. Half our work comes from referrals and repeat clients — that's not luck, that's policy.
We're a bilingual company in a bilingual city. Estimates, contracts, and every conversation on site happen in English or Spanish — whichever your family prefers. From the Valley to South LA, Central LA, and Orange County, we build for working families and property owners who want the job done once, done right, and done legal.
On time, in the window we gave you, with the crew we promised.
Real prices, real timelines, and a no when a no protects you.
Dust contained, tools stacked, streets swept. Every day, not just the last one.
Permits passed, punch lists cleared, and a phone that still answers after final payment.
California requires — and your project deserves — a licensed contractor. Guillen Construction Inc holds CSLB License #1146020, is bonded and insured, and contracts exactly the way state law prescribes, including down payments capped at $1,000 or 10% (whichever is less) on home improvement work. You can verify our license anytime at cslb.ca.gov.
Free on-site estimates. Straight answers on price, permits, and timeline — no runaround.
We reply within one business day — usually faster.
