Hollyburn Maintenance Ltd does an excellent job. Very efficient!! We hadn't washed the the exterior of our house for a couple years because I can't stand the continuous buzz of a power washer. Hollyburn Maintenance Ltd does a soft wash. They removed all the moss did a great job cleaning gutters made the house sparkling clean & they were quiet. Holly, the owner is a very nice lady with good PR skills, not pushy & very honest. I will definitely keep using there services. I would highly recommend Hollyburn Maintenance Ltd. Thanks
