What is construction & post-renovation cleaning?
Construction cleaning is the process of removing debris, dust, and contaminants left behind after renovation or new build work. It happens in three phases: rough clean (ongoing debris removal during construction), final clean (after all trades are done but before you move in), and touch-up clean (final pass before occupancy).
Construction dust is not regular house dust. Drywall dust, concrete dust, and wood dust are fine particles that get into everything — HVAC ducts, behind light fixtures, inside electrical outlets, under baseboards, and into the pores of unfinished wood. Drywall dust is gypsum and paper fibers. Concrete dust contains silica, which is a known carcinogen and requires HEPA filtration to clean safely. Cutting or grinding masonry, brick, or concrete generates respirable crystalline silica that causes silicosis (irreversible lung scarring).
Duct cleaning after a renovation is not optional. Construction dust circulates through your furnace and AC system every time the blower runs. It coats the inside of the ducts, settles on the blower motor, and clogs the air filter within days. A proper duct cleaning uses negative pressure and rotating brushes to dislodge debris, then HEPA vacuums to capture it. Cost is $300-$500 for a typical house and takes 2-4 hours.
Final cleaning includes washing all hard surfaces (counters, floors, windows, trim), vacuuming carpets and upholstery with HEPA filters, wiping down light fixtures and switch plates, cleaning inside cabinets and closets, and removing paint overspray or adhesive residue. The goal is to make the space move-in ready.
Pressure washing the exterior removes concrete splatter, paint overspray, and mud tracked by workers. Use low pressure (1,000-1,500 PSI) for vinyl siding, brick, and stucco. High pressure (2,500+ PSI) is only safe for concrete driveways and walkways. Too much pressure on siding will crack it or drive water behind the vapour barrier.
When you need construction & post-renovation cleaning
- After finishing a basement, addition, or whole-house renovation before moving furniture back in
- Drywall dust visible on floors, counters, and air vents after drywalling and sanding
- Concrete dust or sawdust coating surfaces after demolition or framing work
- Before final occupancy inspection for a new build or addition
- HVAC system running poorly or air filter clogging every few days after renovation
- Paint overspray, adhesive residue, or sticker residue left on windows or fixtures
- Exterior siding covered in mud, concrete splatter, or paint from construction work
- Before staging a house for sale after a flip or major renovation
The Process
What happens from start to finish
Rough clean (during construction)
Ongoing during project, 1-2 hours per dayRemove debris and sweep floors at the end of each work day or trade phase. Bag drywall scraps, wood offcuts, and packaging. Dispose of construction waste in bins or arrange junk removal pickup. Keep dust contained to the work area with plastic barriers and negative air machines if possible.
HVAC protection and duct cleaning
2-4 hours for duct cleaningIf HVAC ducts were open during construction, or if dust got into return vents, schedule duct cleaning before final clean. Technician uses negative pressure system and rotating brushes to dislodge dust, then HEPA vacuum to capture it. Replace furnace filter after duct cleaning.
Surface washing and debris removal
4-8 hours depending on sizeSweep and vacuum all floors with HEPA filter vacuum (required for silica dust from concrete or masonry work). Wet-mop hard floors. Wipe down all horizontal surfaces (counters, windowsills, shelves, tops of cabinets). Remove paint overspray, stickers, and adhesive residue from windows and fixtures.
Window cleaning
2-4 hoursScrape paint and stickers off glass with razor blade. Wash interior and exterior windows with squeegee and cleaning solution. Clean window tracks and sills. Remove construction film or protective tape from frames.
Floor cleaning
2-4 hoursVacuum carpets with HEPA filter. Damp-mop hard floors (tile, vinyl, hardwood). For new hardwood, use pH-neutral cleaner recommended by the flooring installer. Remove grout haze from tile with grout haze remover (do not use vinegar — it etches grout).
Fixture and trim cleaning
2-4 hoursWipe down light fixtures, switch plates, outlet covers, door handles, baseboards, and trim. Remove fingerprints, dust, and paint overspray. Clean inside cabinets, drawers, and closets. Wipe down appliances if installed.
Final inspection and touch-up clean
1-2 hoursWalk through the space with the homeowner or contractor to identify missed spots. Touch up any areas that need re-cleaning. Vacuum and mop one last time. Remove all cleaning supplies and equipment. Run air scrubber or open windows to air out cleaning product smell.
Investment Guide
Construction cleaning pricing is based on square footage, level of dust and debris, and whether you need specialized services like duct cleaning or pressure washing. A typical post-renovation clean for a 2,000 sq ft house runs $500-$1,000. Add duct cleaning ($300-$500) and exterior pressure washing ($200-$400) if needed.
Post-renovation cleaning (per sq ft)
$0.15-$0.35/sq ft
Depends on: Level of dust and debris, accessibility, whether ducts were cleaned, number of windows
Typical house (1,500-2,500 sq ft)
$500-$1,500
Depends on: Basement renovation vs whole house, how much drywall dust, number of bathrooms and windows
Rough clean (debris removal during construction)
$200-$500 per visit
Depends on: Volume of debris, bin rental or junk removal fees, frequency (weekly or after each trade)
HVAC duct cleaning
$300-$500
Depends on: Number of vents and returns, accessibility of ducts, length of duct runs, dryer vent cleaning add-on
Window cleaning (interior and exterior)
$5-$15 per window
Depends on: Size of windows, amount of paint or sticker residue, accessibility (ground floor vs second floor)
Pressure washing (exterior)
$200-$600
Depends on: Square footage of siding, driveway and walkway cleaning, severity of mud or concrete splatter
Touch-up clean (final pass before move-in)
$150-$400
Depends on: Size of space, how thorough the final clean was, last-minute contractor fixes that created new dust

Common problems and risks
- Silica dust from concrete, brick, or masonry is a carcinogen — do not vacuum with a regular shop vac, use HEPA filtration only
- Do not use high-pressure (2,500+ PSI) washing on vinyl siding, brick, or stucco — it will crack siding or drive water behind the wall
- Drywall dust clogs HVAC filters within days if ducts were not cleaned — replace filter immediately after final clean
- Paint overspray on windows must be scraped with a razor blade, not scrubbed — scrubbing scratches the glass
- Do not use vinegar or acidic cleaners on natural stone, grout, or marble — it etches the surface permanently
- If you find asbestos floor tile or pipe insulation during cleaning, stop work and call an abatement contractor — disturbing asbestos is illegal
- Some cleaning companies are not insured for construction sites — verify WSIB coverage and liability insurance before hiring
- If the contractor says they will clean up but does not specify final clean, you will end up doing it yourself or paying extra
