A licensed GC your properties can keep on speed dial

Property managers and owners don't need another vendor — they need one licensed contractor who answers, shows up with insured crews, and closes work orders the first time. That's the business we've built: tenant improvements, unit turns, structural repairs, and the recurring maintenance that keeps buildings leased.

Commercial & Property Maintenance — Guillen Construction

One number covers concrete, framing, drywall, plumbing, electrical, and stucco. Fewer vendors to onboard, fewer trips to schedule, and one invoice your books will like.

Commercial & Property Services

What's included

Tenant improvements

Retail, office, and restaurant build-outs run on real schedules — because your tenant's rent starts when our work ends.

Unit turns & make-readies

Drywall, paint-ready surfaces, plumbing and electrical fixes, and flooring coordination — units back on the market in days, not weeks.

Balcony & walkway compliance

SB 721 / SB 326 structural repairs: we open, rebuild, waterproof, and document elevated elements so inspection findings actually clear.

Storefronts & facades

Stucco, siding, patching, and paint-ready exterior repairs that keep street appeal worth the lease rate.

Maintenance programs

Scheduled walk-throughs and a standing crew arrangement for portfolios — small problems fixed while they're still small.

Emergency & insurance repairs

Water damage, vehicle impacts, vandalism — secured fast, documented for the carrier, rebuilt properly.

How it works

How we work

01

Walk the job

We meet at your property, listen, measure, and give you straight answers — including the ones you didn't ask for. Estimates are free.

02

Price & permits

A written, line-item scope with a milestone payment schedule that follows California law. Plans, engineering, and permits handled.

03

Build

Our own crews, a clean site, and a schedule we actually keep. You get one point of contact and updates you don't have to chase.

04

Walk-through & warranty

We punch the list to zero, pass final inspection, and stand behind the work after the trucks leave.

FAQ

Questions we hear a lot

Can you handle vendor onboarding and COIs?

Yes — certificates of insurance, W-9s, and vendor-portal compliance are routine for us, and we carry the licensing and coverage your asset managers require.

My building failed its SB 721 balcony inspection. Now what?

Send us the report. We scope the flagged elements, price the structural and waterproofing repairs, pull permits, and deliver the documentation that closes the finding — we do this work regularly.

Do you work around occupied units and open businesses?

Constantly. We schedule around tenants, contain dust and noise, and keep paths of travel safe and legal — your tenants' experience is part of the job.

How fast can you turn a vacant unit?

A standard make-ready — patches, texture, fixtures, minor plumbing and electrical — typically runs 3–7 working days depending on scope. Give us the walkthrough and we'll commit to a date.
