Our History


Develop an association of trust and confidence with each of our customers by safely delivering quality and timely services that exceed expectations.

Diamond Building Maintenance Ltd. has proudly served residential, commercial, industrial and warehouse customers since 2002, using only top quality products for all repairs and maintenance services we offer. We started Diamond Building Maintenance because we felt there was a need for high quality services in the industry. We began by providing strata, commercial and residential low-rise & high-rise power washing cleaning and window cleaning services.

Our quality and workmanship was quickly recognized, and our happy customers let us know that they wanted us to expand our window washing and pressure washing services. Over the years, we have invested substantial time and money into industry leading training for our team and high quality equipment. Through ongoing industry training, Diamond Building Management Ltd. grew to include concrete waterproofing, concrete repair, concrete polishing, sealant replacement, exterior painting & coating, investigation of leaks, gutter cleaning, targeted concrete repair, balcony restoration, traffic coating, basement leak repair, roof repair and replacement, and more.

We pride ourselves on our workmanship and work ethic. Due to the trust we have earned from our customers, some of our key clients have invested in our company to provide our crew with the latest in industry training. This, in turn, allowed Diamond Building Maintenance Ltd. to grow to what we are today, and provide our key customers with better service for their buildings and projects.

When teaming up with Diamond Building Maintenance Ltd., you can rest assured that we deliver quality workmanship, on time and within scope. If we can’t do it, we will let you know before proceeding with any changes or extensions on a project. Time is precious, and we want to create a win-win situation for every project.

Diamond Building Services Ltd. maintains active WCB and Liability insurance for all the services we offer.

We have the job covered, and more importantly…YOU!
