TLDR: A construction clean runs in three passes, not one. Most Spokane GCs book the final clean too early, while trades are still walking the floor, and then pay a second crew to redo it. This checklist covers what a real final clean includes, what site readiness looks like before the crew arrives, and the five items that cause almost every punch list callback.
What post construction cleaning in Spokane WA actually covers
Post construction cleaning takes a building from “the trades are done” to “the tenant can move in.” It has almost nothing in common with janitorial work, and the difference is the soil. Drywall dust is fine enough to slip past a shop vac filter and settle again an hour later, so a crew without HEPA filtration is just moving it around. Grout haze, glue labels, paint overspray, and dried mud on the glass need solvents and a razor, plus a tech who knows what will scratch.
Alpine runs construction cleans across Spokane, Spokane Valley, Liberty Lake, Cheney, Coeur d’Alene, and Post Falls. Our techs hold OSHA 10 cards and our supervisors hold OSHA 30. That matters on a site where other trades are still working overhead.
The three phases of a construction clean
Ask five contractors what a construction clean is and you’ll get five answers, mostly because they’re describing different phases. Here’s the sequence that works.
Rough clean. This happens after framing and drywall, before finish work. Crews haul out debris, sweep and shovel, pull nails and screws off the deck, and knock down the heavy dust so painters and flooring installers aren’t working in a cloud. It’s dirty, fast, and cheap compared to the alternative.
Final clean. The detail pass that makes the space handover ready. Every horizontal surface, every pane of glass, every fixture, inside every cabinet. This is the one that gets inspected, and it’s the one that gets rejected when the site wasn’t ready.
Touch-up/Fluff clean. The last pass. This usually takes place after the final punch list items are complete. Removing the final dust and spots from touch ups and patches. Then…project complete.
The final clean checklist
Work top down. Gravity is the whole method, and any crew that starts on the floors will be doing them twice.
High work and ceilings
- Vacuum ceiling grid, tile faces, and any exposed structure or ductwork
- Wipe sprinkler heads, smoke detectors, speakers, and camera housings
- Clean light lenses and troffers inside and out, and remove bulb stickers
- Wipe HVAC diffusers and return grilles, then confirm construction filters were pulled
Walls, doors, and glass
- Spot clean walls for handprints, scuffs, and overspray without burnishing fresh paint
- Wipe door faces, both sides of the leaf, plus frames, hinges, and hardware
- Clean interior and exterior glass, then detail tracks, sills, and frames
- Remove manufacturer labels, tape residue, and silicone from glass and mirrors
- Damp wipe outlet covers, switch plates, thermostats, and panel doors
Floors
- HEPA vacuum carpet and hard surface, corners and edges included
- Auto scrub or damp mop hard floors, then check for haze under raking light
- Remove grout haze and construction adhesive from tile
- Detail base cove, transitions, and the gap behind door stops where dust hides
- Apply finish only if it was scoped; a final clean is not a strip and wax
Restrooms and kitchens
- Clean and sanitize fixtures, partitions, dispensers, and mirrors
- Polish stainless and chrome, then remove protective film from every fixture
- Wipe inside and outside of all cabinets, drawers, and shelving
- Clean appliance interiors, including the gasket and the drip pan
Entry and exterior
- Blow down and pressure wash entries, walkways, and the dock apron
- Clear debris from landscape beds and the parking lot perimeter
- Wipe signage, address numbers, and exterior light fixtures
Where punch list callbacks actually come from
After enough handovers you start to see the same five items. Interior glass with a haze that only shows when the afternoon sun hits it. Dust on top of door frames and the upper track of sliding partitions. Protective film left on stainless appliances and elevator panels. Grout haze on tile that looked fine while the floor was still damp. And label adhesive on window glass, which is the single most common cleaning item on a punch list we’ve seen.
None of these are hard. They’re just easy to miss when a crew is working under a lighting setup that doesn’t match how the space will be lit on opening day. That’s why our supervisors walk each area with a flashlight held low and flat against the surface before we call it done.
Site readiness: when to schedule the final clean
A final clean booked before the site is ready is money spent twice. So we write readiness into the scope. Before our crew shows up, the site needs to have:
- Permanent power and lighting turned on, plus running water
- All trades out of the areas being cleaned
- Temporary floor protection pulled up
- Debris and material staging hauled off
- Clear access, and a working elevator on multi story jobs
If those conditions aren’t met, we’d rather reschedule than clean around a painter. Our construction agreements include a rescheduling clause for exactly this reason, and it protects both sides: you don’t pay for a redo, and we don’t send a six person crew to a site where half the space is still taped off.
One Spokane specific note. From late November through February, we lose daylight early and entries take a beating from sand and de-icer. On winter handovers, plan for an extra entry detail on the morning of the walkthrough rather than assuming Thursday’s clean will still look right on Monday.
What drives the price
We price construction cleaning off production rates, not a flat rate per square foot pulled from a rate card. Five things move a bid: square footage and ceiling height, glass count inside and out, how many phases you want, the floor types and what shape they’re in, and whether the job falls under prevailing wage.
That last one matters in Washington. On a public works job, Davis-Bacon and state prevailing wage rates apply to the cleaning scope too. A bid that ignores it is a bid you should question.
Common questions
How long does a final clean take?
It depends on square footage, glass count, and how well the rough clean was handled. A 10,000 square foot tenant improvement in decent condition is usually a one to two day final clean with a crew of four to six.
Do you work alongside other trades?
For rough and touch-up cleans, yes. For the final clean, no. The area being cleaned needs to be clear, or you’re paying us to clean behind someone who is still generating dust.
Are you insured for commercial construction sites?
Alpine carries two million dollars in general liability plus a twenty five thousand dollar janitorial bond, and we’ll provide a certificate naming your project before we mobilize.
Book a project walkthrough
September and October are heavy months for Spokane completions, and final clean slots fill from the GC side well before the actual handover date. If you have a project closing out this fall, get us on site for a walkthrough now and we’ll build the scope around your schedule instead of the other way around.
