What is the average cost of glass cleaning for a multi-storey new build in Ottawa?

Quotes for a complete post-construction glass clean on a multi-storey new build in Ottawa, covering all interior and exterior window surfaces, can run roughly $800 to $2,000, and homes with extensive glass features like curtain walls, skylights, or floor-to-ceiling windows can go higher. Treat that as perspective rather than a price list, and ask for itemized written quotes.

Why Multi-Storey Builds Cost More

The primary cost driver for multi-storey window cleaning is access and safety equipment. Ground-floor windows can be cleaned quickly using standard tools, but second-storey and third-storey windows require extension poles, extension ladders, or scaffolding, all of which add time and labour cost to the job. The same window takes noticeably longer on the third floor than on the ground floor once you factor in ladder setup, repositioning, and the slower pace required for safe elevated work.

Window cleaning companies often charge more for elevated work, and safe work at height takes extra equipment and people. Ask each company how they will reach the upper windows and how they handle fall protection, and ask whether they have WSIB coverage or a clearance certificate. Some window cleaning companies use water-fed pole systems that let them clean upper windows from the ground using purified water pumped through telescoping poles, which can reduce the cost of upper-storey cleaning by eliminating ladder setup time.

For multi-storey new builds, the type of construction contamination on the glass also affects pricing. New builds collect contamination from multiple trades over many months. Mortar splatter from masonry work, stucco overspray from exterior finishing, and paint drips from soffit and fascia painting can all end up on upper-storey glass. Each of these requires specialized removal techniques beyond simple washing.

As a general pattern, a two-storey production home with a standard window package will usually price lower than a two-storey custom home with specialty glass, and a three-storey home or townhome tends to cost more again because of the additional access requirements. Skylights are often priced separately because reaching them from inside can require a platform setup.

When getting quotes for a multi-storey new build, ask each company specifically about their approach to upper-storey access, and ask for proof of liability insurance and what it covers. Get a few itemized written quotes and make sure each specifies interior and exterior cleaning, construction residue removal, and frame and sill wiping.
