Strata Commercial Advisor

Our FAQ section is not a list of common questions as there are literally hundreds of them, but rather a customized tool for you to ask anything and everything to do with your specific site(s). Please feel free to ask any building related question and if we don’t have the answer for you we will get it from our extensive network of vendors and sub-trades collected over the past 20 years.

Did You Know?

Started in 1996 by two brothers with an entrepeneurial flair for washing window screens of cars waiting for ferry departures, Cleantech has evolved into a full service commercial cleaning company which today offers a broad spectrum of services.

The cleaner just finished the window cleaning and was very efficient, another job well done! Another polite, tidy and respectful employee of Cleantech, what a team – thanks!

Strata Building – Strata Council Member


Strata Council met last week & all Council members (unsolicited) had positive comments about your cleaner and the difference he has made to our condo! He has worked hard to bring the site back to the standard we desire and believe we deserve. This has been noted by Council members and many owners/residents.

Strata Building – Strata Council President


I am very pleased with the professional relationship that has developed between us since you became the Cleantech representative for our building.  I appreciate your usual willingness to listen to my concerns and for your cheerful, positive responses.
