Buyer guide

Hiring a exterior cleaner in Ottawa

What separates a great exterior cleaner from a cheap quote, and the questions worth asking before you sign.

  • Soft washing is not pressure washing

    Siding, stucco and roofs are cleaned with low pressure and a cleaning solution; high pressure on those surfaces forces water behind them and strips finishes. Ask which method they will use on each surface, and be wary of anyone who answers 'pressure wash' for everything.

  • Confirm insurance and working-at-height practice

    Window and roof cleaning means ladders, and on a two- or three-storey Ottawa home that is real risk. Ask for proof of liability insurance and WSIB coverage, and how they access upper storeys.

  • Ask exactly what a window clean includes

    Prices vary because the scope does. Confirm whether the quote covers interiors as well as exteriors, and whether screens, tracks and sills are included or billed separately.

  • Book it around the salt

    Spring is the busiest window because road salt, sand and winter film come off then. Booking early in the season usually means better availability, and pairing it with fall eavestrough cleaning often costs less than two separate visits.

Common questions

Exterior Cleaning in Ottawa, answered

How much does exterior cleaning cost in Ottawa?
Ottawa window cleaning is usually quoted per window, commonly 5 to 15 dollars each for exteriors and 3 to 10 dollars for interiors, which puts most homes between 150 and 500 dollars. A full exterior house wash is priced separately and typically runs 200 to 800 dollars depending on size and how dirty the surfaces are. Confirm whether screens, tracks and interiors are included before comparing quotes.
Is pressure washing safe for siding and stucco?
Not at high pressure. Siding, stucco and roofs should be soft washed, which uses low pressure and a cleaning solution. High pressure can drive water behind cladding and strip finishes, so ask which method the company uses on each surface.
When is the best time to book exterior cleaning in Ottawa?
Spring is the most common, once road salt, sand and winter grime can be washed off. Fall is the other useful window, and many homeowners pair it with eavestrough cleaning after the leaves drop.
How often should a house be washed?
Once a year suits most Ottawa homes. Properties under heavy tree cover, on busy roads, or on shaded north-facing walls where algae builds up may benefit from more frequent cleaning.
