Frequently Asked Questions

You should schedule post-construction cleaning as soon as the final building inspection passes and all trades have completed their work. In Ottawa, this timing can be tricky during winter months when finishing trades may face delays due to extreme cold (-30°C or below), so it's wise to book your cleaning crew 1-2 weeks in advance. Most Ottawa cleaning companies recommend scheduling the rough clean immediately after drywall and major dusty work finishes, with the final detail clean happening 2-3 days before your move-in date. Keep in mind that Ottawa's clay-heavy soil means construction sites tend to produce more fine dust than average, so allowing extra time between construction completion and cleaning is always a good idea.

For a typical Ottawa single-family home renovation, a full post-construction clean takes 1-3 days depending on the scope of the project. A kitchen or bathroom renovation might only need a half-day to a full day, while a complete new build or whole-home gut renovation can require 2-3 days with a crew of 3-4 cleaners. Homes in Ottawa's heritage districts like Centretown, the Glebe, or Sandy Hill often take longer due to detailed trim work, original hardwood floors, and intricate architectural features that require careful hand-cleaning. The timeline also depends on whether the rough clean was done properly after each construction phase.

Post-construction cleaning in Ottawa typically follows three phases: rough clean, light clean, and final detail clean. The rough clean happens during construction after major dusty stages like demolition, drywall finishing, and sanding, and focuses on removing large debris, sweeping, and initial dust control. The light clean occurs once all trades have finished and involves washing surfaces, vacuuming with HEPA filters, and removing adhesive residues and paint splatters. The final detail clean is the most thorough pass, covering window tracks, light fixtures, cabinet interiors, outlet covers, baseboards, and ensuring every surface is move-in ready. Many Ottawa contractors now coordinate the rough clean phase directly with the cleaning company to reduce overall project timelines.

Expect the cleaning crew to arrive with commercial-grade equipment including HEPA-filtered vacuums, industrial scrubbers, and specialized cleaning solutions for different surface types. They will work room by room, starting from the top of the house and working down so dust and debris settle naturally with gravity. In Ottawa homes, crews pay special attention to HVAC vents and ductwork openings since construction dust circulated through your heating system during the build can recirculate for months if not properly addressed. You should also expect the crew to do a final walkthrough with you to identify any areas that need touch-up before they leave.

A rough clean is the heavy-duty first pass done while construction is still underway, focusing on removing large debris, drywall dust, sawdust, and bulk waste from the work area. A final clean is the detailed, meticulous pass done after all construction and finishing work is 100% complete. During the final clean, professionals address every surface including inside cabinets, window sills, light fixtures, outlet plates, door frames, and hardware. Ottawa's notoriously fine clay-based construction dust requires HEPA-filtered vacuuming during both phases, as standard vacuums simply redistribute the particles. The final clean is what transforms a construction zone into a livable home.

Professional post-construction cleaners in Ottawa use a combination of HEPA air scrubbers, negative air pressure machines, and polyethylene barrier sheeting to contain and capture airborne dust. HEPA vacuums with true H13 or H14 filters capture 99.97% of particles down to 0.3 microns, which is critical for the ultra-fine drywall and joint compound dust common in renovation projects. Ottawa homes, particularly older ones in neighbourhoods like Sandy Hill and Old Ottawa South, often have forced-air heating systems that spread construction dust throughout the entire house, so sealing and cleaning HVAC registers is a standard part of the process. Many Ottawa crews also use damp-wiping techniques on all hard surfaces rather than dry dusting to prevent re-suspension of particles.

Professional post-construction cleaning crews use commercial-grade HEPA vacuums, floor scrubbers and burnishers, steam cleaners, pressure washers for exterior work, and industrial-strength air scrubbers to cycle and filter room air. Razor blade scrapers are used for removing paint drips, adhesive residue, and sticker labels from glass and hard surfaces. In Ottawa, where hard water mineral deposits are common, crews also carry water-fed pole systems and deionized water for streak-free window cleaning. Microfiber cloths and mops are preferred over cotton because they trap fine particles rather than pushing them around, which is especially important given the high levels of fine clay dust typical in Ottawa construction projects.

For new hardwood floors, professionals use pH-neutral cleaners specifically designed for sealed wood and avoid excess water, which can cause cupping or warping, a particular concern in Ottawa where indoor humidity swings dramatically between dry winters and humid summers. Natural stone and granite countertops require non-acidic, non-abrasive cleaners since vinegar, lemon-based products, and standard bathroom cleaners can etch or dull the surface. New ceramic and porcelain tile is cleaned with mild alkaline solutions to remove grout haze without damaging the grout joints. Any reputable Ottawa post-construction cleaner will carry surface-specific products and should be able to tell you exactly what they plan to use on each material in your home before they start.

Yes, volatile organic compounds (VOCs) from fresh paint, sealants, adhesives, and new building materials are a legitimate health concern after construction. Professional post-construction cleaners help by using air scrubbers with activated carbon filters that capture VOC molecules, thoroughly cleaning surfaces where off-gassing residue settles, and advising on proper ventilation schedules. In Ottawa, winter renovations pose a particular challenge because homeowners are reluctant to open windows for ventilation when it's -25°C outside, so air purification equipment becomes even more important. Ontario's building materials generally meet low-VOC standards, but the cumulative effect of multiple new materials in a freshly renovated space can still exceed recommended indoor air quality thresholds.

Under Ontario's Workplace Hazardous Materials Information System (WHMIS 2015, aligned with the Globally Harmonized System), all cleaning contractors must have current WHMIS training, maintain Safety Data Sheets (SDS) for every chemical product they use on-site, and ensure proper labelling on all containers. This is enforced by Ontario's Ministry of Labour, Immigration, Training and Skills Development and applies to any post-construction cleaning crew working in Ottawa. When hiring a cleaning company, you should ask to see their WHMIS training certificates and confirm they carry SDS binders on their trucks. Companies that cut corners on WHMIS compliance are more likely to cut corners on the quality and safety of their cleaning work as well.

In Ottawa's older neighbourhoods like Centretown, the Glebe, Sandy Hill, and Rockcliffe Park, homes built before 1990 may contain asbestos in insulation, floor tiles, or textured ceilings, and homes built before 1978 may have lead-based paint. Post-construction cleaning crews are not licensed to remove or abate these materials; that work must be done by certified abatement professionals under Ontario Regulation 278/05 (Designated Substance - Asbestos on Construction Projects). However, a responsible cleaning company will recognize potential hazardous materials and refuse to disturb them, recommending proper testing and abatement first. If abatement has already been completed, the cleaning crew should verify clearance certificates are in place before beginning their work.

In Ottawa, post-construction cleaning typically costs between $0.25 and $0.75 per square foot for residential projects, with most whole-home cleans falling in the $500-$2,500 range depending on the size and scope of construction. A single-room renovation like a bathroom or kitchen usually runs $200-$600, while a full new-build clean for a 2,000+ square foot home can reach $1,500-$3,000 or more. Prices in Ottawa tend to be slightly higher than the Ontario average due to the city's strong construction market and the prevalence of heritage homes that require extra care. Always get at least three written quotes and make sure each one specifies whether rough cleaning, final cleaning, or both phases are included.

The biggest cost drivers are the square footage of the space, the type of construction work that was done (a drywall-heavy renovation creates far more dust than a kitchen cabinet replacement), the number of windows and fixtures, and whether the home has multiple storeys. Homes in Ottawa's heritage districts often cost more to clean because of intricate trim, original hardwood floors requiring specialized care, and plaster walls that generate different dust than modern drywall. The condition of the site also matters: if the construction crew did a poor rough clean or left significant debris, the cleaning company will need more time and labour. Accessibility is another factor, as homes without easy parking or with narrow stairways in areas like Old Ottawa South or Hintonburg add logistical time.

A standard post-construction cleaning quote in Ottawa should include dust removal from all surfaces, HEPA vacuuming of floors and carpets, washing of all hard floors, interior window cleaning, wiping down cabinetry inside and out, cleaning light fixtures and outlet covers, and sanitizing bathrooms and kitchens. Items that often cost extra include exterior window cleaning, pressure washing of driveways or exterior surfaces, carpet deep-cleaning or steam cleaning, air duct cleaning, and removal of heavy debris or construction waste. Make sure to ask specifically about disposal fees, as the City of Ottawa charges for construction waste at its Trail Road landfill and transfer stations, and some cleaning companies pass this cost through while others include it.

The City of Ottawa requires that construction and demolition waste be properly sorted and disposed of at approved facilities, primarily the Trail Road Waste Facility or one of Ottawa's transfer stations. Materials like drywall, concrete, wood, and metal should be separated for recycling where possible, as Ottawa's Integrated Waste Management Master Plan encourages diversion from landfill. Post-construction cleaning companies must transport waste in covered vehicles to prevent debris from blowing onto roadways, and loads over certain weights require a valid waste hauler permit. Dumping construction waste in residential garbage bins or at unauthorized locations can result in fines under Ottawa's Property Standards By-law and Ontario's Environmental Protection Act.

Absolutely. In Ontario, the Workplace Safety and Insurance Board (WSIB) provides mandatory coverage for cleaning companies, and any post-construction cleaner you hire should carry a valid WSIB clearance certificate. This protects you as the homeowner because without WSIB coverage, you could be held liable if a worker is injured on your property. You can verify a company's WSIB status online through WSIB's clearance certificate portal. Additionally, the cleaning company should carry a minimum of $2 million in commercial general liability insurance, which is the standard threshold most Ottawa general contractors require of any sub-trades entering a job site. Ask for proof of both WSIB and liability insurance before any work begins.

Ontario's Environmental Protection Act and Regulation 347 govern the handling, transportation, and disposal of hazardous waste, which in a post-construction context can include solvents, adhesive removers, paint strippers, and certain cleaning chemicals. Hazardous waste cannot be poured down drains, placed in regular garbage, or left on-site, and must be transported to a licensed hazardous waste facility by a registered hauler with proper manifests. In Ottawa, residents can bring small quantities of household hazardous waste to the city's Household Hazardous Waste Depot at Trail Road. Professional post-construction cleaning companies should have documented procedures for hazardous waste handling and be able to show you their waste disposal records upon request.

Ottawa's winters, with temperatures regularly dropping to -25°C or colder, create several unique challenges for post-construction cleaning. Windows cannot be left open for ventilation, so air scrubbers and mechanical ventilation become essential for removing airborne dust and VOCs. Exterior cleaning tasks like pressure washing, window exteriors, and siding cleanup must often be deferred until spring thaw. Salt and road grit tracked in by construction crews throughout winter embed deeply into new flooring and require specialized removal techniques. Indoor humidity drops to 15-20% in heated Ottawa homes during winter, which causes fine construction dust to remain airborne much longer than it would in more humid conditions, making HEPA filtration even more critical.

Spring (late April through June) and early fall (September to mid-October) are the ideal times for post-construction cleaning in Ottawa. These seasons offer moderate temperatures that allow windows to be opened for natural ventilation, comfortable working conditions for crews, and the ability to complete both interior and exterior cleaning in one visit. Ottawa's construction industry is busiest from May through October, so cleaning companies also tend to book up quickly during these months — scheduling 2-3 weeks ahead is recommended. If your renovation wraps up in mid-winter, consider doing the interior final clean right away but deferring exterior cleaning and a final air-quality ventilation pass to spring when conditions allow proper cross-ventilation.

Ottawa experiences one of the widest temperature ranges of any major Canadian city, from -30°C in January to +35°C with humidity in July, and this dramatic swing directly impacts post-construction cleaning. In summer, high humidity causes drywall dust and joint compound residue to become sticky and adhere to surfaces, making it harder to remove but less likely to become airborne. In winter, bone-dry indoor air means dust stays suspended and circulates through HVAC systems, requiring multiple passes with HEPA equipment over several days. Ottawa's clay-rich soil also means that construction sites track in more mineral-heavy dust than in sandy-soil regions, and this clay dust is particularly difficult to remove from grout lines, textured surfaces, and carpet fibres. Professional cleaners adjust their techniques seasonally to account for these Ottawa-specific conditions.

Ottawa's extreme climate can extend the gap between construction completion and final move-in-ready cleaning by days or even weeks compared to milder regions. Winter projects often require a staged cleaning approach: an initial interior clean after construction, followed by a spring exterior clean and final air-quality pass once windows can be opened. Freeze-thaw cycles in March and April can delay exterior work and cause additional mud and debris to be tracked into nearly finished interiors. During Ottawa's humid summer months, freshly cleaned surfaces may develop a haze from settling dust more quickly, sometimes requiring an additional touch-up pass 48-72 hours after the initial final clean. Planning your cleaning schedule around these seasonal realities ensures you get the best results and avoid paying for repeat visits.
