Post-Construction Cleaning Services in Washington

Premier Janitorial Services delivers post-construction final cleaning across the Puget Sound — Seattle, Tacoma, Bellevue, Kent, Renton, Federal Way, Olympia, Sumner, Spanaway, Puyallup, Lacey, Tukwila, Tumwater, Gig Harbor, Fife, Des Moines, and Auburn. Our W-2 crews come in after debris hauling and turn raw construction space into an occupancy-ready, photo-ready finish — drywall dust gone, windows streak-free, fixtures polished, floors sealed-and-finished. General contractors and commercial property managers across the region rely on Premier for clean handovers that close out punch lists on schedule.

Where We Fit in the Construction Cleanup Sequence

There are three distinct phases of construction cleanup, and most cleaning companies muddle them. Premier is explicit about scope so general contractors know exactly what we deliver:

1. Rough Cleanup — debris hauling, large material removal, demo waste. This is typically handled by your debris hauler or the GC’s own crews. Premier does not haul construction debris.
2. Final Cleaning (Premier’s specialty) — drywall dust extraction, paint overspray removal, fixture polish, glass and window cleaning, floor cleaning and sealing, HVAC vent cleaning, restroom and kitchen detail. This is the high-skill, high-margin phase.
3. Occupancy-Ready Turnover — final touch-up before client walkthrough or tenant move-in. Streak-free glass, fingerprint-free hardware, vacuumed soft surfaces, photo-staging-grade detail.

By owning phases 2 and 3 and being explicit about not competing with debris haulers, Premier becomes the cleaner-of-choice for GCs who already have a debris contractor lined up. Clearer scope = faster procurement.

Why Construction Sites Need a Specialist Cleaner

Post-construction cleaning isn’t deep cleaning at higher intensity — it’s a fundamentally different discipline. Premier crews are trained on:

• OSHA respirable crystalline silica compliance — drywall dust, concrete dust, and cementitious materials contain silica. Our crews use HEPA-filtered vacuums and wet-method removal, with documented exposure control protocols.
• Active jobsite safety — hard hats, safety glasses, steel-toed boots, hi-vis vests, and a crew lead trained to coordinate with GCs and subcontractors still on site.
• Surface-specific cleaning — different chemistry for stainless steel, brushed nickel, painted drywall, polished concrete, LVT, and natural stone. The wrong cleaner on the wrong surface costs the GC a punch-list rework.
• Window and glass detail — interior and exterior glass cleaning at scale, including newly installed storefront and curtain-wall glass where construction adhesive residue is common.
• HVAC vent and air-quality prep — duct vent covers cleaned, return-air grills wiped, and (when contracted) coil and filter inspection before tenant occupancy.

Built for General Contractor and Property Manager Procurement

Premier’s structure is designed for the way commercial construction actually procures cleaning:

• 24-to-72-hour turnaround from punch-list close — we schedule around your final walkthrough date, not the other way around.
• W-2 crews, not 1099 subcontractors — every cleaner is a direct Premier employee, background-checked, and W-2 covered for workers’ comp. Important for GC general liability and active-jobsite insurance compliance.
• Certificates of insurance furnished upfront — general liability with project-specific additional insured language when required. We provide COIs the same day a project is awarded.
• After-hours and weekend availability — most final cleans happen overnight or on weekends to avoid disrupting trades or final inspections. Premier rotates crews to cover.
• Square-footage-based pricing — transparent per-square-foot pricing for new construction final cleans, with surcharges for occupied/active areas and a separate quote-line for window cleaning beyond standard interior glass.
• Bonded and insured — all crews bonded and insured for the value of the property being cleaned.

Frequently Asked Questions

Do you haul construction debris?

No. Premier is a final-cleaning specialist, not a junk-removal company. Most GCs prefer this clean separation of scope — your debris hauler clears the rough waste, then Premier comes in for dust, polish, glass, and turnover detail. We can recommend trusted debris partners across the Puget Sound if you don’t have one.

Can you start while trades are still on site?

Yes, with safety coordination. Our crew leads check in with the site superintendent on arrival and work in completed zones while other trades wrap up. We carry hi-vis, hard hats, and steel-toed PPE as standard issue.

How do you handle silica and drywall dust?

HEPA-filtered vacuums on every crew, wet-method removal where appropriate, and N95 respirators per OSHA’s respirable crystalline silica standard. We document exposure controls on request for your safety binder.

What’s a typical price per square foot?

Post-construction final cleaning typically runs $0.15–$0.45 per square foot depending on finish quality required, glass square footage, surface mix, and occupancy schedule. We provide a fixed quote after a walkthrough — no hidden change orders.

How quickly can you get on site?

For pre-scheduled projects, we slot around your punch-list date. For rush jobs, we can typically mobilize a crew within 48 hours across our 17-city service area.

Do you work weekends and nights?

Yes. Most commercial final cleans run after hours or on weekends to avoid disrupting final inspections and trade work. Premier rotates crews to cover.
