Post-Construction Cleaning Markham | Fine-Dust Specialist

Post-construction + post-renovation cleaning across Markham. Fine-dust specialist, HEPA vacuum, finish-safe. Move-in ready in 1 visit.

If you've just finished a renovation in Markham, you already know: the fine dust is everywhere. Your contractor swept, maybe vacuumed. The visible dust is gone. But there's a haze on every surface that keeps coming back because drywall dust is too fine for a regular vacuum. We run HEPA-filtered post-construction cleans across Markham — it's a different scope entirely.

Why Post-Construction is Different

Drywall dust particles are 2–10 microns. Household vacuum filters let particles that small pass straight through. In Markham renovations, this means:

• Fine dust settles on every horizontal surface, then re-airborne every time someone walks through
• HVAC intake grills pull dust into ductwork — it returns for weeks
• Visible haze on glass, mirrors, picture frames
• Dust in electrical outlets and light switch covers
• Sticky residue from caulk and paint overspray

A regular cleaning service will dust, vacuum with a standard filter, and leave. A post-construction specialist works with HEPA-rated vacuums, finish-safe products (no abrasives on fresh paint or new hardwood), and a top-down 3-pass methodology. That's what we bring to every Markham job.

Markham Neighborhoods + Renovation Volume

We handle post-construction cleans across Markham including Unionville, Cornell, Markham Village, Thornhill, Cathedraltown, Berczy Village, Greensborough. Renovation density varies — Unionville and Cornell see heavy reno activity year-round, while newer subdivisions like Markham Village and Thornhill tend to be finish-coat cleans on new builds.

Markham-wide response from Unionville staging. Book 7–14 days ahead for post-construction since we bring a 3-person crew with HEPA equipment.

Markham Post-Construction Pricing

These prices are higher than our regular scope because the work is genuinely harder — HEPA vacuum rental cost, extra product, and a crew of 3 (not 2). But it's a fraction of the $80/hr per-person rates that most Markham post-construction specialists charge.

Finish-Safe Products + Protocols

Fresh hardwood floors in Markham, new marble, freshly painted walls — each needs different handling:

• Fresh hardwood — damp mop only, no standing water, no acid-based product
• New tile grout — needs 72 hours before first wet clean; we ask when grout was sealed
• Fresh paint — dry-dust only for first 2 weeks; water cleaning can lift paint
• New cabinets — often have protective film; we remove carefully per Markham builder standards
• Marble — pH-neutral products only, no vinegar or citrus-based cleaners

We ask for your Markham renovation timeline when you book — when materials were installed, when paint finished — so we know which finish-safe protocol to use per room.

What's Included in a Markham Post-Construction Clean

• 3-pass dust protocol: First pass dry-dust top-down, second pass damp wipe, third pass HEPA vacuum floor and horizontal surfaces
• HVAC intake wipe: All return vents and intake grills so ductwork doesn't re-circulate
• Inside light fixtures: Glass globes, shades, recessed cans
• Inside cabinets: Including drawer tracks and hinge areas
• Window sills + tracks: Where dust accumulates heavily during renos
• Electrical plates: All outlet and switch covers — dust settles behind
• Baseboards + door frames: 3-pass treatment
• Adhesive + caulk removal: From windows, tile, fresh paint — with finish-safe products
• Appliance wipe: Exterior of new appliances still in plastic, all stickers removed
• Final HEPA vacuum: All floors, commercial-grade pass

Most Markham post-reno jobs take 5–10 hours. We finish in one visit.
