Quick Read -

  • Construction dust settles everywhere — including inside cabinets and HVAC systems
  • Window tracks, light fixtures, and vents are commonly missed
  • Professional post-construction cleaning goes far beyond surface wiping
  • A thorough clean protects your investment and your health

          You've just finished a renovation or new build. The contractors have packed up, the final walkthrough is done, and you're ready to move in. But wait — there's a layer of fine dust on everything, and the "clean" your contractor promised? It barely scratched the surface.

   Here's the truth: post-construction cleaning is a specialty service for a reason. It's not just about making things look nice — it's about removing hazardous dust, debris, and residue that can affect your health and damage your new finishes.

1The Dust Inside Your Cabinets

   Construction dust is incredibly fine. It doesn't just settle on countertops — it gets inside every cabinet, drawer, and closet. Even if the doors were closed during construction, that dust found its way in.

What we do: We open every cabinet and drawer, wipe down all interior surfaces, and remove dust from shelving. Your dishes and clothes shouldn't be covered in drywall dust.

2Window Tracks and Sills

   Windows get a quick wipe during most contractor cleanups, but the tracks? They're packed with sawdust, drywall dust, and debris. This buildup can actually prevent windows from opening and closing properly.

What we do: We vacuum out window tracks, scrub them clean, and wipe down all sills and frames. Your windows should glide smoothly and look spotless.

3Light Fixtures and Ceiling Fans

   Look up. See that haze on your new light fixtures? Construction dust loves to settle on horizontal surfaces, and light fixtures are magnets for it. Ceiling fans are even worse — they'll spread dust throughout your home the moment you turn them on.

What we do: We carefully clean all light fixtures, ceiling fans, and any overhead elements. No more dust raining down when you flip a switch.

4HVAC Vents and Returns

   This is the big one. Construction dust gets sucked into your HVAC system and settles in every vent and return. If you don't clean these, you'll be breathing that dust for months — and it can damage your HVAC system over time.

What we do: We remove vent covers, clean them thoroughly, and wipe down the visible ductwork. We also recommend changing your HVAC filter immediately after construction.

5Baseboards, Door Frames, and Trim

   All that beautiful new trim work? It's covered in a fine layer of dust that makes it look dull. Paint splatters, caulk residue, and fingerprints are common too.

What we do: We wipe down every inch of baseboard, door frame, and trim. We remove any paint drips or caulk smears that don't belong. Your woodwork should look crisp and clean.

6Behind and Under Appliances

   Appliances get installed, but nobody cleans behind them first. That means construction debris is trapped back there — and it's not coming out on its own.

What we do: When possible, we pull out appliances and clean behind and underneath them. Starting fresh means starting clean — everywhere.

7Sticker and Label Residue

   New windows, appliances, and fixtures come covered in stickers, labels, and protective film. Contractors often leave these behind, and the adhesive residue can be stubborn.

What we do: We remove all stickers, labels, and protective coverings. We use appropriate cleaners to dissolve adhesive residue without damaging surfaces.

The Bottom Line

Post-construction cleaning isn't optional — it's essential. A proper clean protects your investment, your health, and ensures you can actually enjoy your new space from day one. Don't settle for a quick wipe-down when you deserve a thorough, professional clean.

   At MMKAY Cleaning Services, we specialize in post-construction cleaning that goes beyond the surface. We know where the dust hides, and we don't stop until it's gone.
