Clean surfaces are the result. How we get there is the difference.
Every property we touch reflects our standards — not just our skill. When we show up to clean your windows, roof, siding, or gutters, we're not just checking a box. We're protecting what you've worked hard to build, and we take that seriously.
Good service shouldn't just leave your home looking great. It should leave you wondering why you didn't call us sooner.
Brandon Markel started cleaning windows in Petoskey in 2008. Two years later, Thru Glass was born with one simple standard: do excellent work and treat people right.
Early on, Brandon recognized that exterior cleaning isn't just about appearances. It helps homeowners protect their investment, enjoy their space, and feel proud of where they live. That insight has driven every decision since.
As demand grew, so did our services — expanding from window cleaning into roof cleaning, pressure washing, gutter care, and seasonal maintenance. Every addition was driven by the same goal: make it easier for clients to keep their property in great shape.
Thru Glass exists in this community, not just in it. We show up as volunteers, participate in the local chamber of commerce, and believe businesses should make the places they operate better — not just profitable.
Internally, we've built a company where careers are real. Our team members are skilled professionals who take pride in their craft and support their families through meaningful work. Many have built long-term futures here — and that's something we're proud of.
Thru Glass has grown, but our standards haven't shifted.
We invest in training. We prioritize communication. We build systems that keep every job consistent and every client informed.
We're proud of the work we do — and grateful you're considering trusting us with your property.
