How Much Does Window Cleaning Cost in Durham Region?

Professional window cleaning in Durham Region typically runs between $150 and $400 for a standard two-storey detached home, depending on the number of windows, their condition, and whether interior cleaning is included. Here's what goes into that price and how to know if you're getting good value.

What Affects the Price

Number and Size of Windows

Most window cleaners price per pane or per window unit. A standard Durham Region semi-detached might have 15–20 windows; a larger detached in Whitby's north end or Oshawa's Kedron neighbourhood can have 25–35. Larger picture windows, bay windows, and floor-to-ceiling glass panels take longer and cost more per unit.

Interior vs. Exterior Only

Exterior-only cleans are faster and cost less — typically 60–70% of the full interior and exterior price. A full interior and exterior clean takes roughly twice as long because the crew needs to work inside the home, protect floors and furniture, and detail the interior frames and sills.

Storeys and Access

Second and third-storey windows require ladders, additional setup time, and safety equipment. Most companies charge a modest premium for above-ground-floor access. If your home has hard-to-reach windows over a roof line, a garage, or a conservatory, expect the quote to reflect the added complexity.

Condition of the Glass

Windows that haven't been professionally cleaned in several years — or waterfront Whitby properties with mineral deposit buildup from Lake Ontario spray — may need a first-time deep clean at a higher rate. Once on a regular schedule, maintenance cleans are faster and less expensive.

What Should Be Included

• Hand-scrubbed and squeegeed interior and exterior panes
• Screen removal, cleaning, and reinstallation
• Track and sill detailing
• Frame wipe-down
• Final walk-through and touch-ups

Professional vs. DIY

DIY window cleaning is feasible for ground-floor windows. Above the first storey, the risk of ladder falls and the difficulty of getting a streak-free result without professional-grade squeegees and technique makes professional cleaning the practical choice for most homeowners. A professional crew can clean an entire two-storey home in 2–3 hours. The same job done by hand typically takes a homeowner a full day with less consistent results.

How Often Should You Clean?

Twice a year — spring and fall — is the standard for most Durham Region homes. Homes near construction zones, busy roads (like homes on Taunton Road in Oshawa or Dundas Street in Whitby), or the waterfront benefit from a third mid-summer clean to handle pollen, dust, and mineral deposits.
