Post-Renovation Cleaning: What Your Contractor Skips

When a home renovation wraps up, the contractor typically does a "broom clean" as final scope: sweep up visible debris, collect major trash, remove tools and equipment. The homeowner gets the keys back and assumes the space is ready to use. Over the next 2-4 weeks, they discover fine construction dust on window sills, in HVAC vents, on top of cabinets, inside newly installed appliances, and redistributing through the air system whenever the HVAC runs.

This is the gap that post-renovation cleaning fills. Here is what a real post-reno clean actually covers and why it matters.

The Dust Problem

Renovation work — drywall, sanding, paint prep, tile work, flooring — generates fine particulate across a range of sizes. The visible debris is the large stuff. The problematic dust is:

• Drywall sanding dust (1-10 microns, airborne for hours, settles over days)
• Paint dust and overspray (sub-micron, can persist in air for weeks)
• Tile dust and grout dust (variable sizes, heavy accumulation near work areas)
• Wood dust from trim, flooring, cabinetry work
• Concrete and masonry dust from any structural work

This fine dust is what standard "broom clean" misses. It settles throughout the home, gets pulled into HVAC systems, and redistributes for weeks.

What Post-Renovation Cleaning Actually Covers

A proper post-reno cleaning scope includes:

Dust management:

• HEPA vacuuming of all horizontal surfaces including ceiling edges, door frames, window sills, top of cabinets
• Wet wiping of all vertical surfaces (walls near work area especially)
• HVAC register and return grille cleaning
• Replacement of HVAC filter (construction loads dramatically shorten filter life)
• Air scrubber operation during cleaning to capture airborne particulate

Surface detail:

• Every horizontal surface wet-wiped
• Windows cleaned (interior, plus exterior if accessible)
• Window tracks and frames (collects dust heavily)
• Floor vacuumed then mopped (multiple passes typical for heavy dust)

Cabinetry and millwork:

• Inside every cabinet (every drawer, every shelf)
• Inside appliance compartments (dishwasher, refrigerator, oven, microwave if newly installed)
• Sticker and film removal from new fixtures, appliances, glass surfaces
• Adhesive residue removal

Fixture detail:

• Light fixtures (including fan blades, interior of flush-mount fixtures)
• Electrical outlets, switch plates, thermostats
• Plumbing fixtures (faucet detail, drain covers, shower fixtures)

Final detail:

• Final dust pass on touched surfaces
• Spot check for missed areas
• Walk-through with homeowner

Typical labour: 6-12 hours for a medium-scope renovation (single room or cluster of rooms), longer for whole-home renovations.

The HEPA Requirement

This is the non-negotiable for post-reno cleaning. Standard vacuums do not filter fine construction dust — they exhaust it into the air. A commodity cleaning crew with consumer vacuums on a post-reno job actually makes the dust situation worse in the short term.

Real post-reno cleaning uses HEPA-filtered commercial vacuums (CRI Seal of Approval where applicable). Air scrubbers (HEPA-filtered air filtration units) running during cleaning capture airborne particulate. Microfibre cloths for wet wiping capture fine dust mechanically rather than pushing it around.

When evaluating a vendor, ask to see their equipment. If the answer is "we use good vacuums," that is not specific enough.

The Timing

Ideal timing:

• Construction substantially complete (all trades done except minor punch-list)
• 24-48 hours before the homeowner moves in or begins heavy use
• After any final touch-up work by the contractor
• Before furniture is moved in (an empty space is dramatically easier to clean)

Cleaning while trades are still working is wasted — the next trade's activity redistributes dust. Cleaning after furniture is in place misses much of the scope that depends on open access.

Single-Visit vs. Phased

Whole-home renovations often benefit from phased cleaning:

• Phase 1: rough clean after drywall and paint, before finish trades
• Phase 2: final clean after all trades complete
• Phase 3: touch-up day before move-in

Single-room renovations typically work with a single deep clean at end of trades.

Phased cleaning costs more in aggregate but produces dramatically better outcomes for larger renovations where dust would otherwise migrate between rooms.

Pricing

Canadian urban-market post-renovation cleaning:

• Single room renovation: $300-600
• Kitchen renovation (typical): $450-900
• Bathroom renovation: $300-550
• Full basement renovation: $600-1,400
• Whole-home renovation (single pass): $900-2,200+ depending on size

Pricing reflects the scope and HEPA equipment requirements. A post-reno quote that matches standard cleaning pricing is not actually post-reno cleaning.

The Dustline Approach

Dustline specializes in post-renovation residential cleaning across Canadian metros. Our equipment is 100% HEPA-certified for this work. We deploy air scrubbers during cleaning where warranted. We coordinate with contractors and designers to schedule around final trades. Photo documentation and a final walk-through with the homeowner are part of standard scope.

If your renovation is wrapping up and the contractor's "construction cleaning" is not addressing the fine-dust scope, the post-reno cleaning conversation is the missing layer. The difference between standard and HEPA-grade is visible within days of moving in.
