A Note From Donmar Company About COVID-19

To Our Valued Customers,

We recognize that with the constantly changing COVID-19 situation in our country and around the world, this is an unprecedented time for everyone. With all the uncertainty, we want to let you know that we are here for you, and let you know about the precautions we are taking to keep our technicians and you and your family safe.

  • Our technicians will wear gloves, facemasks, and booties at all times while working, and stay in the work area unless its necessary to move around the home.
  • We will refrain from handshakes and adhere to social distancing
  • To minimize hand to hand transactions with the technicians, we have a payment tab available on our website, or you can call the office at anytime to process a payment for services rendered
  • Our technicians have sanitizing wipes stocked on their trucks, and will use it prior to entering your home
  • If any of our employees are showing any signs or symptoms of being sick, we will keep them home without hesitation

If you have any suggestions or can think of anything else we can do as a precaution, we are happy to listen. We will continue working so that your home is a source of comfort to you, and so the air quality is clean and safe. Again, the safety of our technicians, you, and your family are our number one priority.

Please be safe and stay healthy.

Sincerely,

Donald Wills

President
