Window Cleaning
We offer regular, chemical, and construction / post-construction window cleaning services. Our team of professionals is trained to select the best methods based on the type of surface being cleaned to ensure outstanding results.
Whether your building is a high-rise or low-rise, caulking and weatherproofing can effectively help lower energy costs and decrease the risks of water leaks. It can be applied to any gaps in the structure of a building, and is commonly used around windows.

We are your one-stop cleaning and maintenance specialists for all your needs, from metal cleaning and spider control, to replacement of dryer vents and solar panel cleaning. Rest assured that our workers are fully trained. You'll be delighted with the results.

I am writing this letter of recommendation in support of PrimeTech Building Services Ltd.  We have contracted their services beginning in the spring of 2016 to clean all the exterior windows at The Palace Pier, located at 2045 Lake Shore Boulevard West in Etobicoke three (3) times per year, as well as to provide other related services such as spider treatments, cleaning and replacement of dryer vents, caulking and weatherproofing.  The spring, summer and fall cleans were started and completed on schedule.  The Board of Directors were pleased with the results and high quality of work.  The exceptional performance of PrimeTech’s crew in customer service, workmanship and safety was noted and appreciated.  We will continue using their services this year and, given the reasonable pricing, no doubt on into the future.  I feel very confident in recommending PrimeTech Building Services for a high-rise window cleaning and related services.
