We clean ceilings first and floors last

Our construction cleanup covers every room

A remodel or new build leaves two kinds of mess. The contractor usually hauls off the big stuff, like drywall scraps and lumber ends. What stays behind is the fine layer nobody notices until the sun comes through a window. It sits on top of door frames, inside every cabinet, along the baseboards, in the window tracks and on the ceiling fan blades. That second mess is the job we do. We start by picking up leftover scraps and packaging so nothing gets dragged across a new floor.

We work from the ceiling down, and dry before wet. Fan blades and the tops of door and window trim get vacuumed with a brush head first. Then the walls, then the cabinets inside and out, then the counters and appliances. Floors come last, because everything above them drops dust while it is being cleaned. Wipe a counter before the upper cabinets are done and you will be wiping it again an hour later. That is how a cleanup doubles in length.

You can check the work yourself. Run a finger along the top of a door and it should come back clean. Look across a dark countertop with the light behind it and there should be no white haze. Pull out a drawer and the bottom should be free of grit. Heat register covers come off and get washed, since they catch more dust than almost anything else in the house. If a spot fails one of those checks, that spot is not finished yet.

• Window sills and tracks cleaned out
• Floors vacuumed, then mopped last

Drywall dust needs a dry pass first

Drywall dust behaves differently from everyday house dust. It comes from sanding joint compound, and it is fine enough to hang in the air long after the sanding stops. It settles slowly, over the next day or two, onto surfaces that were already wiped. That is why a cleanup done the morning after the last sanding can look perfect at noon and dusty by evening. We ask when the sanding finished so the final clean happens after the air has settled.

The mistake we see most is going straight to a wet mop. Water turns drywall dust into a thin paste, and when it dries it leaves a chalky film on floors and a streaky haze on dark cabinets. Then the whole surface has to be washed again, sometimes more than once. A regular household vacuum has its own problem, because the fine dust passes through the bag and blows back out the exhaust. So the dust comes off dry first, and the damp cloth only comes out after.

Helena houses run the furnace for much of the year, and that matters on a remodel. If the registers were open while the walls were sanded, dust went into the ducts. It will blow back out the first time the heat kicks on. We wash the register covers and vacuum as far into each opening as a hose will reach, but duct cleaning is a separate trade. Ask your contractor to change the furnace filter once the sanding is over, and again after our clean.

Old plaster walls leave a grittier mess

Plenty of the older housing near downtown Helena is brick on the outside with plaster and lath walls inside instead of drywall. When a remodel opens one of those walls, the mess is heavier than drywall dust. It is sand and crumbled plaster with splinters of lath mixed in, plus dust that sat inside the wall for decades. That grit works like sandpaper. Push a broom or a dust mop through it and you can scratch the floor you are trying to clean. So we vacuum it up instead.

Those older houses also have more places for dust to hide. Original wood trim has deep grooves along every edge, and each groove holds a line of grit until a brush gets into it. Cast iron radiators catch dust down between the fins, where a cloth cannot reach. Old wood floors often have gaps between the boards that fill up with plaster dust. We work these spots by hand with a brush and a crevice tool, because a quick wipe leaves the dust sitting in every groove.

Newer wood frame houses around town and out in Montana City make a different kind of mess. They are drywall throughout, often with open floor plans and tall ceilings. Dust travels from one end of the house to the other with no walls to stop it. High ledges and the tops of tall windows collect a thick coat, and those spots get skipped because nobody looks up there. We clean them from a ladder before we touch anything below them.

Dry winter air keeps the dust moving

Montana air is dry for most of the year, and it gets drier indoors once the furnace is running in the cold months. Low humidity lets fine dust stay in the air longer, and static holds it on plastic and new appliance fronts. That is one more reason timing matters. The final clean works best after the last trade has packed up, painters and finish carpenters included. If trim is still being cut in the next room, the dust lands right back on what we just cleaned.

Helena is a windy town, and a house under construction usually has its doors propped open for days at a time. Wind carries dirt in from the lot and piles it in the corners and along the bottom of the walls. In spring, bare yards on new lots turn to mud, and work boots track it across new floors and up the stairs. We loosen dried mud on entries and stair treads before we wipe them, so it does not smear into the grain of new flooring.

New windows arrive with labels and tape residue on the glass, and the outside panes usually carry a coat of dust from the lot. We clean windows inside and out, and the labels come off with the glass kept wet so grit under the blade does not scratch it. Pressure washing and sidewalk and driveway cleaning are on our list of services as well. Fresh concrete needs time to cure before it gets pressure washed, so tell us when the driveway was poured.
