To Our Valued Customers

This is to inform customers and contractors that all upcoming installations & service work will be postponed until further notice due to uncertainty of COVID-19.

Our employees & their families mean a lot to us and have agreed to go on EI until this is over, I myself will be answering my phone and helping to the best of my ability in self-isolation as I have a lung disorder and run a high risk of fatality if I were to contract the virus.

Again we apologize for any inconvenience and wish all of you to keep safe and appreciate the cooperation. Please don’t hesitate to call me about any questions or concerns. Wishing you and your loved ones good health during this difficult time.
