How do I clean a newly renovated commercial elevator lobby in an Ottawa building?

Cleaning a newly renovated commercial elevator lobby in Ottawa is a specialized project that demands a methodical approach, the right equipment, and a clear understanding of the high-traffic, high-visibility nature of the space. Elevator lobbies typically feature a concentrated mix of hard surfaces — polished stone, large-format tile, metal cladding, glass, and painted drywall — all of which require different cleaning methods and products. Getting this right the first time matters because a lobby is the first impression visitors have of the entire building.

The Right Sequence Makes All the Difference

Start with a rough clean before you attempt any detailed surface work. In a commercial renovation context, this means removing all construction debris, packaging materials, cardboard, tape, and bulk dust from the space entirely. Only once the space is clear of physical debris should you begin the detailed cleaning sequence — always working from ceiling to floor and from the back of the lobby toward the exit. Begin with ceiling fixtures, ventilation grilles, and any recessed lighting. Construction dust settles on every horizontal surface, and disturbing ceiling areas first means that fallout lands on surfaces you haven't cleaned yet rather than ones you've already finished.

HEPA vacuuming is non-negotiable for a commercial post-construction clean. Standard commercial vacuums recirculate fine drywall and concrete dust back into the air through their exhaust — this is the single most common mistake made on commercial cleanup jobs. A proper HEPA vacuum captures 99.97 percent of particles down to 0.3 microns, which is what you need to actually remove construction particulate rather than just move it around. Run an air scrubber continuously throughout the cleaning process to capture airborne dust that gets disturbed during the work — fine construction particles remain suspended for 48 to 72 hours after disturbance, which is a serious concern in an enclosed lobby space.

For polished stone floors, marble, or large-format porcelain tile — common choices in Ottawa commercial lobbies — avoid any acidic cleaners. Acids dissolve grout and etch polished stone surfaces permanently. Use a pH-neutral cleaner and an industrial floor scrubber to remove the construction grime layer. Grout haze is a particularly common issue after tile installation; use a purpose-made grout haze remover applied carefully according to the manufacturer's directions, then rinse thoroughly. Metal cladding and elevator door surrounds should be cleaned with a microfibre cloth and a mild degreaser — never abrasive pads, which scratch brushed or polished metal finishes.

Glass panels, sidelights, and lobby windows require glass-safe solvents to remove paint overspray, tape adhesive residue, and construction film. New glass is especially vulnerable to scratching, so ensure any cloth used on glass surfaces is completely free of grit particles. Work in straight strokes rather than circular motions to avoid trapping debris under the cloth.

From an Ontario regulatory standpoint, commercial post-construction cleaning must comply with WHMIS 2015 requirements — all chemical products used on site require proper labelling and safety data sheets. HVAC duct cleaning is essential after any commercial renovation; construction dust trapped in the building's ductwork will recirculate through the lobby every time the system runs, undoing your surface cleaning within days. Budget $400 to $800 for duct cleaning in a typical Ottawa commercial building section, and confirm this is included in your contractor's scope.

For a commercial elevator lobby, professional post-construction cleaning in Ottawa typically runs $1,500 to $8,000 depending on square footage, surface complexity, and the extent of the renovation. Always get a minimum of three written quotes that specify exactly which surfaces and services are covered.
