“We are very pleased with Anson and his company Superior Maintenance Service. He provides a reliable window cleaning service at reasonable prices.


We were given his name by another office in town, and we are more than happy to give Anson and his company a referral to other business in the Alliston area. We are happy to support a local resident and his business.”

He is very reliable and attentive to his work and offers very reasonable rates. I would recommend him to other businesses in the area.”

“For friendly, prompt and courteous service along with affordable prices I would highly recommend the team of Doug & Anson Milligan (Superior Maintenance Services).

My rating would definitely be 10++. I am very fortunate to be one of their clients. Well done boys.”

They have kept our outside windows and common areas of our condominium building sparkling clean.

The cleaning team clearly takes pride in their work and are easy to work with and very approachable.
