The experience and knowledge to keep you looking your best

We are all about long-term relationships. And we are always looking for ways to stand out in order to help those relationships thrive. It doesn’t end there; SDA puts great energy and thought into forging lasting relationships with our staff and suppliers. Our low employee turnover and high company morale seem to indicate that we’re succeeding.

Our top priority is very happy customers

We test our abilities to prove this daily. Our discipline and concern for detail is legendary. We believe that quality maintenance programs and janitorial services should work to enhance real and intrinsic property values.

Every year SDA Building Services continues to support a special charity of their choice.

This year we are proud to announce that we are supporting The Canadian Breast Cancer Foundation and in turn supporting those who live with breast cancer, families who have lost loved ones to breast cancer and also those who are continually striving for a future without breast cancer.

We are honored to be a part of this incredible cause.
