Martinez, Contra Costa County
Post-Construction in Martinez, CA
KCS provides post-construction cleaning for commercial projects across Martinez and Contra Costa County — new construction, tenant improvements, and remodels. General contractors working in the Contra Costa County region use us because we sequence cleanly into their schedule: rough clean after major trades, final clean before inspection, touch-up before the owner walks Martinez projects on handover day. We are licensed, bonded, and insured, and certificates of insurance are issued promptly for your project file.
Construction activity in Martinez spans office build-outs, retail and restaurant TIs, school and church renovations, and medical suite remodels — from projects along Alhambra Avenue corridor to work near John Muir National Historic Site. Every one ends the same way: fine dust on every surface and a deadline. Our HEPA-equipped crews detail from ceiling grid to baseboard, and our floor specialists protect brand-new VCT, stone, and polished concrete during the clean.
If you have a Martinez project approaching final inspection, send us the plans or book a site walk. We bid flat by phase, hold the number, and staff nights and weekends when the schedule compresses. Call (925) 301-5566 — the earlier we see the Martinez site, the smoother your handover. Rough, final, and touch-up phases can be bid together or separately, matched to your punch-list schedule.
What's Included
Three-Phase Coverage
Rough, final, and touch-up cleans quoted together or separately, sequenced to your construction schedule and punch list.
HEPA Dust Removal
HEPA-filtered vacuums and microfiber tack systems pull fine drywall and silica dust off every surface — including ceiling grid, ledges, and inside cabinetry — instead of pushing it around.
Glass & Fixture Detail
Sticker, label, paint, and overspray removal from windows, storefronts, and fixtures using razors and solvents applied correctly, so coated glass and finishes are not damaged.
New-Floor Protection
Fresh VCT, polished concrete, stone, and LVT are cleaned by floor specialists using the right pads and chemistry — no hazing, scratching, or stripped factory finish.
