Our Story

Cleantech Service Group has been proudly serving Metro Vancouver since 1989, when our founding company, International Building Maintenance, was first incorporated. Beginning with core exterior services including professional window cleaning, pressure washing, and gutter cleaning, we quickly built a strong reputation across Vancouver, Burnaby, Surrey, Richmond, and North Vancouver for delivering exceptional results and customer satisfaction.

As client demand grew throughout the early 1990s, we expanded into janitorial contracts, and in 1996, Cleantech Janitorial Management was incorporated to manage our growing operations. Building strong client relationships and a commitment to excellence, we continued to grow our presence as a leading facility maintenance provider across Metro Vancouver.

In 2011, both companies merged to form Cleantech Service Group — a unified, full-service facility maintenance company with decades of combined expertise and resources, positioning us as one of Metro Vancouver's most comprehensive and trusted facility maintenance providers.

Today, Cleantech Service Group is a proud partner to strata, commercial, and industrial clients across Greater Vancouver, offering a wide range of facility maintenance solutions built on quality, reliability, and personalised service on every project we undertake.
