Should I hire a professional cleaner or do post-construction cleanup myself in Ottawa?

For a full post-construction clean after a new build or major renovation, hiring a cleaning company is usually the better choice — and for good reason. Post-construction cleanup is fundamentally different from regular house cleaning, and the equipment, knowledge, and time required can put it beyond what a homeowner can realistically handle alone.

A big reason to hire a professional is dust control. Construction dust — especially drywall dust and concrete dust — is extremely fine. A regular household vacuum without a proper filter can blow much of it back into the air through the exhaust. Cleaning companies that do this work typically use HEPA vacuums, and many also run air scrubbers that filter airborne dust during the cleaning process. That equipment is expensive to buy for a one-time job, which is a big part of why hiring a crew that already has it often makes more sense.

Ottawa's winters add another layer of complexity. If your construction happened during the winter months, the heating system may have been circulating fine construction dust through your ductwork. That dust can sit in vents, registers, and duct runs throughout the home, and cleaning surfaces without addressing the HVAC system means dust can resettle afterward. Ask any company you are considering whether they handle vents and registers and whether they can coordinate duct cleaning as part of the overall scope.

There are situations where DIY makes sense. If you did a minor renovation — a single bathroom update, a backsplash installation, or a small flooring project — and the dust and debris are limited to one area, basic cleanup with damp cloths, a good vacuum with a HEPA filter, and standard cleaning products is reasonable. Wiping countertops, vacuuming visible dust from a small room, or cleaning up minor debris from a weekend project are all perfectly manageable.

However, for a full new build, a gut renovation, a kitchen remodel, or any project that involved drywall, sanding, or concrete work across multiple rooms, hiring a cleaning company is usually worth it. Consider what your time is worth — a crew with commercial equipment can work through a whole house far faster than one person with household tools, and with a better result. The cost of a professional clean is also small compared to the value of the renovation itself and the cost of potential damage from using the wrong products on new surfaces. Ask for itemized written quotes so you know exactly what you are paying for.

Also consider liability. Before you hire, ask the company for proof of liability insurance and what it covers — for example, if a ladder damages a ceiling or a product stains a new countertop. Ask whether they have WSIB coverage or a clearance certificate as well.
