About us

Hi, I'm Jeremiah Johnson. In the summer of 2017, my wife, VIcky, and I moved to the Knoxville area to be closer to family after attending college in Florida for several years. It didn't take long for us to fall in love with the beauty of East TN. After spending a couple years in lawn care, I discovered you could get paid to clean windows. I could not imagine how many great people I would meet, and how satisfying it would be to brighten so many homes and businesses with a mop and squeegee. In 2025, I decided to start Glasstastic Window Cleaning Services because I love what I do and I want to brighten as many homes and businesses as I can. East TN is too beautiful to cloud the view with dusty windows, let us make your windows look glasstastic today!

Frequently asked questions

Question

Do you clean in the rain?

Yes, we do. Unless it is heavy rain or a severe thunderstorm, we do clean in the rain. We are confident in our skills, even if it's a little wet. Also our work is guaranteed, so, rain or shine, if you notice that we missed something, we will gladly come back and fix it.

Question

How long does your guarantee cover?

We understand that sometimes streaks and smudges can be hard to see on a cloudy day. That's why we are willing to come back anytime within 7 days of your original cleaning.

Question

What is excess debris and why is it not included in a normal cleaning?

Excess debris on windows are things like hard water stains, artillery fungus, paint, silicone, and bug spray. We are able to remove all of these. However, we have to price them differently due to the increased amount of time required to remove them.

Question

What should I do before you arrive?

We ask that you move all valuable or breakable items away from the windows before we arrive. We also ask that if a window is inaccessible, you provide at least 2 ft of clearance in front of the window with enough room to open any blinds, shutters, or curtains. We will gladly assist in moving large pieces of furniture, at our discretion.

Question

What should I do after you arrive?

Relax, and let us make your windows look glasstastic! At any time, if you have any questions, please feel free to ask. If you notice something we've missed, please let us know. We want you to be completed satisfied with the results and the experience.

Question

My windows are cloudy. Are you sure you cleaned them?

After we clean your windows, if they still look cloudy you may have broken seals. This means the seal between the two panes of glass has failed due to heat, age, etc. We recommend you contact Keith Window Company for repairs. You can reach them at 865-524-2424, or keithwindow.com.
