Message From The Owner

Growing up in Meaford, ON, I’ve always had a passion for competitive sports, from Soccer, Rugby, Hockey and Snowboarding - just to name a few.

Welcoming 2 beautiful children into my life naturally forced some of the previously mentioned beloved past times to get sidelined, but my desire to focus and build something ensued.

Hence, Denni’s Window Cleaning+ was born.

Denni's emerged from our collective ambition to restore respect within the blue-collar service sector.

The frustration of dealing with workers who either arrived late or failed to complete promised tasks prompted us to ask why such mediocrity was tolerated.

Our mission is to shift this paradigm, reviving a time when there was a familiar and trustworthy relationship with those servicing our homes or businesses.

Don’t Take Our Word For It…

  • Dayna A.

    The team at Denni’s Window Cleaning were professional and did an amazing job. My house is a very tall three story building and they were able to get to the top with ease and clean windows that hadn’t been touch in years!

    Highly recommend as they hand wash everything vs other companies I’ve used in the past with water poles that always leave residue behind and don’t get to the sills. Great job all around!

  • Daryan A.

    After an extensive renovation, I was extremely cautious in selecting a window cleaning company.

    Alex and his team delivered from start to finish with excellent communication, transparency in the quotation/scheduling process followed by a top-notch quality job cleaning our windows and gutters. I will definitely use Denni’s Window cleaning again!

  • Colin G.

    Super pleased with the friendly and careful crew from Denni’s who cleaned our windows today. They arrived when they said they would, and were courteous and pleasant to talk to. They also did a great job removing all the spiderwebs around the windows on our rural home.

    Definitely would recommend them will have them back in the fall again.

  • Jesse A.

    Such a pleasure working with these folks - a throwback to a time when contractors cared passionately about the work they do. I will certainly be using Denni's again in the future - I didn't realize windows could get that clean!

    Wonderful service and sparkling clean windows! The Denni's team was warm, caring, attentive to detail, and so helpful. Right from the first interaction at the door, they were polite, professional, and responsive. Such a successful experience that I've engaged them to restore my deck next. Highly recommend!
