Post-construction office cleaning: getting it ready

Post-construction office cleaning starts after the last trade has left. Clear out the debris, then remove dust from the top down with a HEPA vacuum and damp microfiber cloths, clean the glass, and do the floors last. Construction dust keeps settling for days, so plan for a second dusting pass before people move back in.

When should you schedule it?

After the work is truly finished: painters, flooring installers, electricians and the punch list. If you clean while trades are still working, their dust lands on everything you just wiped.

Before cleaning day, ask the contractor to:

• Remove leftover materials, tools, offcuts and debris, as their contract allows
• Take protective film and stickers off windows, fixtures and appliances, or tell you which ones can come off
• Tell you the cure time for any new floor finish, sealant or paint before it's cleaned
• Point out anything that shouldn't get wet, like new millwork that hasn't been finished

What do you need?

• A vacuum with a HEPA filter. A shop vacuum without a fine filter blows drywall dust right back into the air.
• Plenty of microfiber cloths, more than you think
• An extension duster for high ledges and the tops of partitions
• Buckets, warm water and a mild all-purpose cleaner
• Glass cleaner and a squeegee
• Dust masks and gloves
• Trash bags and a box for the small hardware and parts you'll find

How do you clean an office after construction, step by step?

1. Ventilate. Open windows if you can. Ask the building whether the HVAC system should run during the cleaning, or stay off until the dust is down.
2. Clear the floor. Pick up debris, screws, wire ties and packaging so you can move freely.
3. Dust from the top down. Start high: the tops of door frames, partitions, shelving and cabinets, light fixture exteriors and the exterior grilles of ceiling diffusers. Use the extension duster. Dust falls, so anything below gets cleaned after.
4. Vacuum walls and ledges. Run the HEPA vacuum's brush attachment over walls, window sills, baseboards and ledges before you wipe anything. Wiping first turns dust into streaks.
5. Damp wipe everything. Barely damp microfiber cloths on every hard surface: sills, baseboards, doors, switch plates, outlet covers, cabinet fronts and the inside of cabinets and drawers. Rinse or switch cloths often.
6. Glass. Wipe the dust off first, then clean with glass cleaner and a squeegee. For paint specks, ask the glazier or contractor what's safe on that glass before using a scraper; coated and tempered glass can scratch.
7. Restrooms and the kitchen. New fixtures collect dust and grout haze. Wipe the dust off before you use any cleaner, and check with the installer before using anything on new grout or stone.
8. Floors last. HEPA vacuum carpet and hard floors, slowly, in two directions. Then damp mop hard floors with clean water and a little mild cleaner, changing the water often. Follow the installer's instructions on new floors.
9. Bring furniture in. Once the floors are done, set up desks and chairs and wipe them down as they come out of the wrapping.
10. Second pass. A few days later, dust and damp wipe the flat surfaces again. Fine dust that was still in the air has settled by then.

What are the common mistakes?

• Wet mopping before vacuuming. Drywall dust and water make a paste that smears and dries into a film.
• Dry dusting with a feather duster. It just moves the dust into the air and onto what you already cleaned.
• Running the HVAC with the old filter. The system pulls construction dust through and blows it back out. Ask the building or the contractor about changing the filter after the work.
• Cleaning before finishes have cured. Water or cleaner on a fresh finish can mark it.
• Moving furniture in too early. It ends up covered and has to be cleaned twice.

FAQ

When should post-construction cleaning happen in an office? After the last trade has finished, including painters, flooring installers and electricians. Clean while work is still going on and the next round of dust lands on everything that was just wiped.

Why does construction dust keep coming back after cleaning? Fine dust hangs in the air and settles for days, and the HVAC system pushes more out of the ducts once it runs. Plan on a second dusting pass a few days after the first, and ask about changing the HVAC filter.

Can you mop construction dust? Not first. Wet mopping fine drywall dust turns it into a paste that smears. Vacuum with a HEPA vacuum first, then damp mop with clean water, changing it often.
