How Often Should You Get Your Windows Cleaned?
Wondering how often to schedule window cleaning in Nashville, Brentwood, or Franklin, TN? Here's what actually affects your windows — and when to call a pro.
Most homeowners in Nashville, Brentwood, Franklin, College Grove, and the greater Middle Tennessee area ask us this before they ever book a job: "How often do I actually need this done?"
The honest answer? It depends — but there are a few factors specific to Middle Tennessee that most people don't know about.
Nashville's Hard Water Is Working Against You
Nashville has notoriously hard water — meaning it carries a high concentration of dissolved calcium and other minerals. When your sprinkler system hits your windows, or when hard water runs off your roof or siding, and down your glass, those minerals get left behind as the water evaporates.
When that happens enough times over enough months, you're no longer dealing with dirty windows — you're dealing with mineral deposits that have bonded to the glass itself. Over time, those deposits etch into the surface and can cause permanent damage that no amount of cleaning can reverse.
For homes with irrigation systems running near the house, we typically see mineral buildup start causing real problems within 12 to 18 months of no professional cleaning. At that point, you're not just paying for a cleaning — you're paying for restoration work or, in the worst cases, glass replacement.
Our General Recommendation by Home Type
Exterior-only maintenance: Every 3–4 months for most Nashville-area homes will keep your home looking pristine and your windows healthy
Full interior + exterior: Twice a year is the standard for most of our clients, although you can get away with once per year on the interior since it is not facing harsh weather like the exterior.
High-exposure homes (pool nearby, heavy tree coverage, irrigation hitting the glass): Exterior window cleaning once per quarter will keep things in great shape
If you're in Franklin, College Grove, Belle Meade, and other areas with more tree coverage your windows are also dealing with significant pollen load from March through May. That alone adds a cleaning cycle most homeowners never account for.
One Sign You've Waited Too Long
Run your finger along the inside edge of your window frame where the glass meets the seal. If you feel a chalky or gritty residue and the glass still looks spotty after wiping — that's mineral etching starting. It's not dirt, and it won't come off with a paper towel and Windex.
That's when you need someone who knows the difference between a general maintenance cleaning to remove dirt and a proper restoration to remove hard water staining — and has the technique and experience to match the solution to the problem.
The Maintenance Plan Most of Our Clients Land On
After an initial full clean, most of our Nashville and Brentwood clients settle into a quarterly or semi-annual exterior maintenance schedule. It keeps mineral buildup from ever reaching the damage stage, visits are efficient, and your home consistently looks the way it should. Not to mention the tens of thousands of dollars it saves you by preventing window replacement costs.
If you're not sure where your windows stand, we're happy to take an honest look — even if the answer is that you don't need us yet.
Our estimates are always free: reach out to schedule service anywhere in Nashville, Brentwood, Franklin, Belle Meade, Green Hills, College Grove, TN or surrounding areas.
