How do I get quotes for cleaning a large commercial construction project in Ottawa?

Getting accurate, comparable quotes for a large commercial post-construction cleaning project in Ottawa requires more preparation than simply calling a few companies and asking for a price. The quality of the quotes you receive depends directly on the quality of information you provide to the contractors bidding on the work. A well-prepared request for quotation saves time, reduces misunderstandings, and ensures you can make an apples-to-apples comparison between bidders.

Start by preparing a scope document that includes the total square footage of the space broken down by area type, such as office space, corridors, washrooms, mechanical rooms, parking, and amenity areas. Include the type of construction work that was performed, whether it was a new build, gut renovation, or tenant fit-up, because this directly affects the amount of dust and debris the cleaning crew will encounter. Specify the types of flooring, wall finishes, and fixtures throughout the building, as different materials require different cleaning methods and products. Note any specialty areas such as server rooms, kitchens, medical suites, or clean rooms that have higher cleaning standards.

Request itemized written quotes from more than one company. Each quote should clearly break down the work into phases: rough cleaning, final cleaning, and touch-up cleaning, which some companies price at a daily or hourly rate. For a large commercial project, totals can run into the tens of thousands of dollars depending on the scope and condition of the space, so the line-by-line breakdown is what makes quotes comparable. Ask each company to specify what is included and what is considered an add-on, particularly window cleaning, HVAC duct cleaning, exterior pressure washing, and parking garage cleaning.

Before accepting any quote, ask for the documents that matter. Ask whether the company has WSIB coverage or a clearance certificate, ask for proof of liability insurance and what it covers, and ask for references from similar-sized commercial projects they have completed in Ottawa. Ask whether they will be using their own employees or subcontracting portions of the work, as this affects quality control and insurance coverage. For large projects, request a detailed cleaning plan that outlines crew size, equipment to be used, estimated timeline, and the sequence of work across different areas of the building.

Timing your quote requests matters too. Start reaching out to cleaning companies well before your anticipated cleaning date, since waiting until the last minute can limit your options when crews are busy with other projects. Invite prospective contractors to conduct a site walk-through before submitting their quote, as this results in far more accurate pricing than a quote based solely on square footage and drawings.
