I had them come and clean for the first time since I bought this house two years ago. The price was right as I used a Groupon coupon.
Dale is the owner and he's been doing this for twenty years. He brought his sharp young helper, a recent transplant from Ontario.
They showed up exactly on time for the appointment. They took their shoes off at the door and took care not to scratch my hardwood with their equipment.
They were very courteous and sensitive to come in my home, as I'm generally a private person, because they do have to go into every room! They were efficient and quick and had the job done in under an hour.
My advice to homeowners would be to have your house tidy before they arrive, and make sure furniture is moved to provide access to vents and returns. This way, they can get the job done faster and do a good job.
I was very happy with this company. I would hire them again, and recommend them as responsible service providers.
