How much does post-construction cleaning cost for a new garage build in Ottawa?

As a rough perspective, quotes for post-construction cleaning after a new garage build in Ottawa can run roughly $200 to $800, depending on the size of the garage, whether it is attached or detached, and the level of finish involved. A basic garage with a concrete slab floor and simple interior sits toward the lower end. A finished garage with insulated and painted walls, coated floors, built-in storage, or a heated workshop space sits toward the higher end, because the detailed cleaning of finished surfaces takes more time and care.

What Garage Cleaning Involves

Garage post-construction cleaning is different from cleaning a living space because the priorities shift. The biggest task is typically concrete floor cleanup — removing mortar droppings, drywall mud splatters, paint overspray, and construction adhesive from the slab. If the floor is going to receive an epoxy coating or sealer, ask the coating installer how they want it prepared, because contamination on the slab can cause a coating to fail. Cleaning crews may use floor scrubbers and concrete degreasers for this work; ask for floor cleaning to be listed as its own line on the quote.

Exterior cleanup around the new garage is often the overlooked cost. After a garage build, the surrounding area can have wood scraps, packaging materials, concrete spillover, displaced gravel, and general construction debris. Ask whether hauling that away is included in the cleaning quote or left to your builder, and agree it in writing. If a bin is needed and would sit on the street, boulevard or sidewalk, it needs a City of Ottawa Temporary Construction-related Encroachment (TCE) permit, so agree in writing who is getting it; the end of a driveway near the street can also be City land, so check before the bin arrives.

Timing matters too. A garage finished in winter may have frozen residue and ice-trapped debris that is easier to deal with once it thaws, so a spring cleanup can take longer. Ask whether the cleaning company would rather wait for warmer weather.

For a basic unfinished garage, a thorough DIY cleanup with a rented shop vacuum and some elbow grease is reasonable. However, if your garage has finished walls, coated floors, windows, or electrical panels that need careful cleaning around, hiring a cleaning company can be worth it. Incorrect cleaning of a new concrete floor, for example, can leave stains or cause problems for a sealer later.
