Why Exterior Window Cleaning Matters

Dirty windows not only affect the aesthetics of your building but can also impact energy efficiency and indoor air quality. Layers of grime can block natural sunlight, making spaces darker and less inviting. Our exterior window cleaning services ensure a streak-free finish that improves your property’s overall appearance while protecting glass surfaces from long-term damage. Trusted by businesses across Ontario, we make sure your windows shine, reflecting the professionalism of your brand. Regular cleanings also reduce maintenance costs and help avoid expensive repairs.

How We Achieve Spotless Exterior Windows

Our cleaning process begins with a thorough inspection of your building to identify any specific challenges, such as hard water stains or persistent grime.

We then use industry-grade equipment, including water-fed poles and eco-friendly cleaning agents, to provide a deep clean. For high-rise buildings, we leverage advanced methods like drone technology or rope-access cleaning to reach every corner safely and efficiently.

Our team prioritizes both results and safety, ensuring your property’s windows are cleaned to perfection without any disruption. Whether it’s regular maintenance or a one-time service, we deliver gleaming results every time.

 The team at LBM was fantastic – they arrived on time for each day they were scheduled. As this work required rented equipment at our own cost, it was wonderful to see urgency on their end in an effort to mitigate costs.

Thanks for your help in finding out their timelines today. It was very much appreciated. I don’t know who this could be passed on to but could you please let the Supervisor know that this is the second year the same two individuals attended the Unit to complete this task. Similar to last year, they were fantastic, efficient and thorough. The work they did was terrific and they were a pleasure to have in the building. Very professional.

 They answered the phone near 2:00am and arrived within an hour to address an emergency flood cleanup. As an FM I appreciate the responsiveness and would highly recommend them.
