Moving Into a New Build in Cornell or Berczy? Your First-Clean Guide
A brand-new Markham home looks finished, but fine construction dust hides in every vent, track and cabinet. Here's what a proper first clean covers before you unpack — and why new builds need it more than most people expect.
Markham keeps building. The master-planned communities of Cornell and Berczy add crisp new detached homes and townhouses every season, and there’s steady new construction near the town centre and the Markham Pan Am Centre. If you’re about to take possession of one of them, congratulations — and a heads-up: a brand-new home that looks spotless is usually anything but. Here’s what a proper first clean covers before you move a single box in, and why a new build needs it more than most people expect.
A new home isn’t a clean home — yet
Construction is a dusty business, and the finest of that dust — drywall and sanding residue — is almost invisible until the light hits it. By handover it has settled into places a builder’s broom never reaches:
- Inside kitchen and bathroom cabinets, drawers and closets, ready to coat whatever you put away first
- Along window tracks, sills and behind the glass
- In vents, returns and the tops of door frames and baseboards
- On top of light fixtures, trim and the fridge and range hood
On top of the dust, new builds come with the usual site residue: sticker adhesive on windows and appliances, paint specks and overspray, and grout haze filming new tile. None of it wipes away with a quick pass — it needs the right technique and products so you don’t scratch brand-new finishes.
Why the dust matters more than it looks
Fine construction dust is exactly the kind of particulate you don’t want circulating through a sealed, freshly built home — it’s an irritant, and once your HVAC starts running it moves that dust from room to room. That’s why we clean new builds with reusable microfibre that captures the fine stuff in the cloth rather than a dry sweep that relaunches it into the air, and with eco-certified, non-toxic products so your first breaths in the new place aren’t a lungful of solvent. It’s the same health-first approach we bring to every home — it just matters even more when a house is starting from a construction baseline.
What a first clean actually covers
Builders often do a rough sweep, but a genuine move-in-ready clean is a different job. Our post-construction cleaning works through the home in detail:
- Fine-dust removal on every surface — cabinets inside and out, closets, baseboards, trim, doors, switches and vents
- Residue removal — stickers, adhesive, paint specks and grout haze cleared from glass, tile and fixtures
- Inside appliances — oven, fridge, dishwasher and range hood
- Windows, sills and tracks, and a full floor clean finished appropriately to brand-new materials
- A touch-up right before you take possession, on request
The goal is simple: you walk in, and it’s genuinely ready to live in — nothing to wipe down before you unpack.
Do it while the home is empty
Like a move-in clean, a first clean is far more effective — and better value — on an empty home, when we can reach inside every cupboard and closet and get to the floors edge to edge. If you can, book it for after the builder’s final walkthrough and before the movers arrive. Tell us your possession date and we’ll schedule around it.
New builds and heritage homes are different jobs
One thing we’ve learned cleaning across Markham: the city’s homes aren’t interchangeable. A new Cornell or Berczy build needs dust knocked down and site residue cleared without scratching untouched finishes. A century home near Main Street Unionville, by contrast, asks for a gentler, more careful hand around original wood, older tile and painted trim. We scope each home honestly rather than running the same package over both — which is exactly why a “first clean” for a new build and a deep clean for a heritage house look quite different when we’re done.
Ready for a genuinely move-in-ready home?
Clean Proper cleans across Markham — from the new communities of Cornell and Berczy to historic Unionville — as a proudly Ukrainian-owned, fully $2M-insured residential company, with the same trusted cleaner each visit. Once you’re settled, many new homeowners switch to a regular or bi-weekly routine to keep that just-moved-in feeling.
