How Much Does Basement Cleaning Cost in Ottawa?

Basement cleaning price depends on factors like the basement's size, condition, clutter level, and whether mould, water damage, or deep cleaning is involved.

The good news is that basement cleaning doesn't have to be expensive. Prices in Ottawa vary based on size, condition, and the type of cleaning you need. This guide breaks it all down in simple terms, so you know exactly what to expect.

Average basement cleaning cost in Ottawa

Basement cleaning cost in Ottawa usually falls between $150 and $600, depending on the size and condition of the space. Here is a quick breakdown:

Basement size	Light clean	Deep clean
Small (under 500 sq ft)	$150 to $220	$250 to $350
Medium (500 to 1,000 sq ft)	$220 to $320	$350 to $450
Large (over 1,000 sq ft)	$320 to $450	$450 to $600+

These numbers can shift based on clutter, mould, pests, or extra tasks like carpet cleaning. If your basement was flooded or used for storage for years, expect the higher end of the range.

What affects basement cleaning cost?

Several things change the final price of your basement clean. Here is what matters most:

1. Size of the basement

Bigger spaces take more time and more hands on deck. A finished basement in a home near Barrhaven or Kanata will cost more to clean than a small unfinished one in a Centretown condo.

2. Level of clutter

A basement packed with boxes, old furniture, and forgotten items takes longer to clear and clean. Sorting and hauling add to the cost.

3. Type of clean

• General cleaning: dusting, sweeping, wiping surfaces
• Deep clean: scrubbing floors, walls, corners, and vents (see our Ottawa deep cleaning cost guide for a full price breakdown)
• Move in/out clean: full reset before or after moving
• Post construction clean: removing dust and debris after renovation work, covered in our Ottawa post-construction cleaning guide

Each type comes with a different price point based on the time and effort needed.

4. Mould or moisture issues

Ottawa basements can face dampness, especially in older homes near the Rideau Canal or Ottawa River. Mould removal or moisture treatment adds to the total cost.

5. Frequency of cleaning

One-time cleans usually cost more per visit than recurring service. Booking regular visits often comes with a lower rate.

When mould needs more than a cleaning

A cleaning crew handles dust, dirt, cobwebs, and surface grime. Mould is different, and the right fix depends on how much there is. Health Canada's guide to moisture and mould sorts it by size:

Mould area	What Health Canada advises
Small: 3 or fewer patches, under 1 m² in total	You can usually clean it yourself with proper precautions
Medium: more than 3 patches, or 1 to 3 m²	Get a professional assessment; cleanup may be possible with the right safeguards
Large: a single patch over 3 m²	Get professional help

Tell your provider about any mould when you book. That way the quote reflects the real job, and you'll know early if you need a remediation specialist instead of a cleaning team.

Keep your basement drier between cleans

Moisture is what turns a dusty basement into a musty one. Health Canada recommends keeping indoor humidity between 30% and 50%, and suggests these steps for basements:

• Run a dehumidifier if the space feels damp.
• Store items in plastic bins instead of cardboard boxes, and never set cardboard directly on the floor.
• Keep storage uncluttered, especially along exterior walls.
• Remove carpet from basement floors where you can.

In Ottawa, check the basement after the spring thaw and after heavy rain. Look for damp spots, water stains, and musty smells, and fix leaks early before they turn into a bigger cleaning job.

How often should you clean a basement?

Most basements need a deep clean once or twice a year. Light touch-ups every few months help keep dust, allergens, and pests away. If your basement is finished and used often, a general cleaning every one to two months keeps it fresh and livable.

Basements that store seasonal items, like holiday decorations or winter gear, only need a thorough cleaning before and after each seasonal change.

Tips to save on basement cleaning costs

• Declutter first: Remove items you plan to donate or toss before the cleaners arrive
• Bundle services: Combine basement cleaning with a full home cleaning visit for better value
• Book recurring visits: Regular cleaning plans often cost less per visit than one-time bookings
• Clear a path: Make sure boxes and furniture are easy to move around so cleaners can work faster
• Flag problem spots: Mention water stains, pests, or mould when you book so the team brings the right tools
• Check the lights: Replace burnt-out bulbs so cleaners can see into corners and under stairs

Small steps like these can lower your final bill without cutting corners on quality.
