Fourteen Knox County locals and a lot of clean glass
Sparkle Pane started in 2012 with one ladder, one van and a Bearden route. Thirteen years later we are still family run, still flat priced, and still walking every job with the customer before we load up.

Our story
Started with one ladder and a Bearden route
Renata Alvarez cleaned windows for someone else for six years before she started doing it her own way. The thing that bothered her was the pricing: hourly quotes that crept, jobs that got rushed at the end of the day, and customers who never quite knew what they were going to pay.
So Sparkle Pane was built around a flat written price. You get a number before anyone touches your glass, and that number does not move, even on the days when we underestimate the job. Thirteen years later it is still the rule, and it is the single thing customers mention most when they call us back.
We are fourteen people now, running three residential crews and two commercial routes out of a shop on Kingston Pike. We still do the walk-through on every job. If something is not right in the daylight, it gets done again before the van leaves.

How we work
Four rules we do not bend
They are simple, they are on the job sheet, and every new cleaner learns them before they touch a squeegee.
We quote flat, not hourly
You get a written price before we start. If the job takes longer than we thought, that is our problem, not your invoice.
Safe around pets and plants
Biodegradable solutions, beds wetted before and after, and gates checked twice so nothing with four legs gets out.
The same faces come back
Crews keep their neighbourhoods. Most repeat customers see the same two cleaners season after season.
Streak-free or we return
Spot something in the light after we go? Call within seven days and we come back out. No argument, no charge.
