Post-construction cleaning in Spokane — dust gone, build move-in ready
Construction dust gets into every track, vent, and finish joint. The job at the end of a build isn't to "clean" — it's to get the dust out before the owner walks through, before the inspector signs off, and before the punch list adds three days you didn't budget for.
Spokane Cleaning Group runs post-construction and remodel cleaning across Spokane and Spokane Valley for general contractors, remodelers, small commercial owners, and homeowners finishing a renovation. HEPA-grade dust control, phase-based scheduling, certificate of insurance on request.
We focus on small-to-mid commercial builds and residential renovations. If your project is over 25,000 square feet or involves regulated abatement (asbestos, lead, mold), it's outside our scope — we'll refer you to a contractor who specializes in larger or hazardous work.
The three-phase scope — rough, final, detail
Three standard phases. Pick the ones you need. Most projects use Final only; bigger or more sensitive builds use all three.
Rough clean. Bulk debris removal, scrap drywall pickup, pallet wrap and site trash out, sweep-out of the slab or subfloor. Run before flooring, paint, or finish trades arrive. Makes the space safe and workable for follow-on crews. Typically priced at the low end of per-square-foot rates.
Final clean. The full handover clean. Dust every surface (tops of doors, window casings, light fixtures, baseboards, vent covers), floors mopped or vacuumed by material, glass and mirrors streak-free, restrooms sanitized, sticker and adhesive residue removed from new windows, appliances, and fixtures. This is what gets you to inspection-ready.
Detail clean. A third pass for HVAC diffusers, light lenses, behind-toilet detail, deep grout edges, hardware polish, and the spots that bother an owner during their first walkthrough. Used on higher-finish jobs or any handover where the GC wants zero punch-list cleaning items.
For residential remodels (kitchen plus bath, basement finish, addition), Final is usually enough. For new commercial buildouts or higher-end residential new construction, Final + Detail is standard.
Equipment, dust control, and safety
Construction dust doesn't stay where the work happened. It migrates through HVAC, settles on finished surfaces in adjacent rooms, and recontaminates everything you already cleaned. The equipment matters.
HEPA vacuums. Commercial HEPA units on every job, not shop-vacs with regular filters. HEPA captures the fine drywall and concrete dust that standard vacuums recirculate back into the air.
Air scrubbers and containment. For sensitive handovers and occupied-adjacent work, we deploy negative-air machines and poly containment to keep dust out of finished areas. Standard on projects with phased occupancy.
Microfiber and tack-cloth systems. Drywall and concrete dust binds to electrostatic surfaces — paper towels and cotton rags just spread it. Microfiber and tack cloths capture it.
PPE and site compliance. Full PPE for every crew member, dust-rated respirators where the SDS calls for them, boot covers in finished areas, site-specific safety briefings to align with your safety plan. We follow your site's rules, not ours.
We don't do regulated abatement (asbestos, lead, microbial). If we find suspect material during the clean, we stop, document it, and notify you so you can bring in the right contractor.
Pricing: per sq ft, per phase, or flat project
Three pricing models — pick what fits your RFP or budget approach.
Per square foot (most common for commercial). Standard finishes typically run $0.25–$0.50 per square foot for Final clean. Rough clean adds $0.10–$0.20 per square foot. Detail clean adds $0.15–$0.30 per square foot. Higher finishes (luxury residential, medical, dental) run higher.
Per phase (best for sequenced work). Each phase is bid separately so you can pay only for the phases that fit your schedule. Useful when occupancy dates shift and you need to peel off a phase.
Flat project (best for turnkey turnovers and residential remodels). A single quoted price for the whole scope. We do a site visit or plan review, write a scope, and quote a fixed number. The price holds unless scope materially changes.
Sample project pricing for Spokane and Spokane Valley:
- 600 sq ft office remodel: $250–$450 (Final), $450–$750 (Rough + Final)
- 850 sq ft kitchen and bath remodel: $300–$550 (Final), often combined with grout or floor restoration
- 1,200 sq ft retail buildout: $450–$800 (Final), $750–$1,300 (all three phases)
- 2,400 sq ft new residential build: $750–$1,500 (Final), $1,300–$2,400 (Final + Detail)
- 3,200 sq ft tenant improvement: $1,000–$1,800 (Final), $1,800–$3,000 (all three phases)
Estimates after a 15-minute site visit or photo and plan review.
Scheduling around your trades
Build schedules slip. Trades overlap. The cleaner who shows up at 8 AM Monday when you needed them Friday afternoon costs you the inspection slot.
How we schedule:
- Pre-job walk with the super. Confirm scope, access, parking, dumpster location, outstanding trades, and any finish materials we need to protect or avoid.
- Flexible shift starts. Early morning, evening, or weekend starts to avoid trade conflicts.
- Phased mobilization. For sequenced jobs, the same crew runs each phase so they already know the building.
- Inspection-aligned final cleans. Scheduled tight to the inspection or owner walkthrough so dust doesn't have time to resettle.
- Last-minute requests. If the occupancy date moves up, we'll find a way to cover it — same-day mobilization isn't unusual on small jobs.
For residential remodels, scheduling is simpler — we work around the trades you're managing directly, and the handover is usually you to the homeowner instead of contractor to inspector.
Sample projects and scope by square footage
Project snapshots from recent Spokane and Spokane Valley work:
Project A — 3,200 sq ft tenant improvement, downtown. Rough clean before flooring install, then Final clean over two days including HEPA filtration and window detail. Handed over to GC for owner walkthrough on schedule.

Insurance, COIs, and contractor documentation
General contractors and property managers need documentation that matches their compliance requirements. We provide what your office needs without making you chase it.
- General liability insurance with limits standard for small commercial work
- Certificate of insurance issued with your project or GC listed as additional insured, returned within one business day of request
- W-9 and vendor onboarding completed before the first invoice
- Safety briefing acknowledgment signed before mobilization on any active job site
- Itemized invoices for accounts payable, with project code or PO field included
- Final clean signoff with photo documentation by room or zone, useful for handover packets
For residential remodels, this layer is usually unnecessary — the homeowner just wants the work done and an invoice. We scale documentation to the audience.
Questions clients ask first.
Do you provide a certificate of insurance with my project listed as additional insured?
Yes. Send the project name, GC name, and your insurance compliance contact, and we'll have the COI issued and returned within one business day. We can list multiple parties (GC, owner, lender) on the same certificate when the compliance form asks for it. This is standard, not an upcharge.
Can you start cleaning during construction or only after?
Both. Rough cleans happen during construction — usually after demo and framing, before flooring or finish. Interim cleans between phases keep finished areas from being recontaminated by later trades. Final cleans happen after all trades are out. For tight schedules we'll stage the work around your remaining trades.
How do you handle HVAC dust so we don't burn through new filters?
For projects where HVAC is running, we use HEPA vacuums and tack cloths on diffusers rather than blowing dust into the system. For containment-required jobs, we deploy air scrubbers and negative-air machines to capture airborne particulates before they reach the return. Some projects need a filter change after we leave; we'll flag it in the handover notes if so.
Do you do residential remodels or only small commercial?
Both. Residential remodels (kitchen, bath, basement finish, addition, full renovation, new build) and small commercial (tenant improvements, retail buildouts, office remodels, light industrial) are roughly half-and-half of our post-construction work. Same equipment, same phase structure — just different audiences and documentation needs.
What's the difference between Rough, Final, and Detail?
Rough is bulk debris and site trash, run during construction to make the space workable for follow-on trades. Final is the full handover clean before inspection or owner walkthrough — every surface, every track, every fixture. Detail is a third pass for HVAC diffusers, light lenses, behind-fixture detail, and the spots an owner notices on a first walkthrough. Most projects need Final only. New commercial and higher-end residential typically need Final plus Detail.
