Your build is done. The trades are out. The walk-through with the client is next week. Now the space needs to look clean. Floors should shine. Windows should be clear. No dust in the corners.

Post-construction cleaning in Portland is its own job. It is not the same as nightly janitorial. There is drywall dust, paint overspray, stickers on new glass, and concrete haze on tile. Miss any of it and the client sees it on punch list day. Use this checklist before you book a cleaning sub. It will save you a punch list round you did not plan for.

Phase 1: Rough Clean (Before Final Finishes Touch-Up)

The rough clean happens after the trades finish but before you do your own final walk. The goal here is to clear the big stuff.

Bag and haul all debris, scrap, and trash
Sweep out every room, including closets and behind doors
Remove stickers, labels, and tape from new fixtures and glass
Vacuum HVAC grilles and return vents so dust does not blow out on day one
Wipe down walls to catch drywall dust before paint touch-up

Skip the rough clean and you will grind dust into fresh paint. You will also lose hours of your own time sweeping instead of finishing trim.

Phase 2: Final Clean (After Touch-Up, Before Punch List)

This is the clean that has to look perfect. The client walks the space in a few days, and your reputation rides on what they see.

Clean all glass inside and out — windows, mirrors, shower doors, glass partitions
Scrub tile and grout. Remove concrete haze and grout film
Detail floors: vacuum, mop, strip any construction film off VCT or LVP
Wipe down all baseboards, door frames, and switch plates
Clean inside cabinets, drawers, and closets
Polish fixtures: faucets, hardware, light trims, outlet covers
Vacuum and spot-clean all upholstered furniture and built-ins
Sanitize all restrooms, top to bottom, including partitions and vents
Final dust pass on every horizontal surface, including high shelves and vents

A good final clean takes a full crew a full day for a 5,000 sq ft space. Less than that and you are cutting corners. You will see them.

What to Ask Your Cleaning Sub Before You Book

Not every cleaning company does post-construction work. Most janitorial crews are set up for nightly office work, not dusty build-outs. Before you book, ask these questions:

Have you done post-construction cleans on commercial projects in Portland?
What is your crew size for a build-out this square footage?
Do you bring your own HEPA vacuums and microfiber, or do we supply them?
Are you bonded and insured for construction sites?
Can you hit a fixed punch list date? What happens if a trade runs late?
Do you warranty the clean through client walk-through?

If they hesitate on any of those, keep looking. You do not want to find out on punch list day that your sub does not work on construction sites.

What to Skip (And What Costs You If You Do)

Skip final clean to save two days on schedule. You will lose a week on punch list. Skip window interiors to save money. The client will see every fingerprint. Skip grout haze on tile. The client will see it the first time they mop. Post-construction cleaning is not the place to cut scope.
