People often ask how often their windows should be cleaned. The honest answer is that it depends on your home, but the seasons give a good rhythm. Here’s how the year usually goes.

Spring, the big one

Winter leaves salt, grit and grime on the glass. A spring clean clears it and lets the light back in. It’s the most popular time to book by far, so reserve your spot early.

Summer, keep it clear

Pollen, dust and insects build up quickly through summer. A mid-season clean keeps the view sharp when you’re using the house most, and RainBlock helps it stay that way through summer storms.

Fall, set up for winter

A fall clean takes off the summer’s build-up and the season’s webs, and leaves the glass clear for winter. Fall dates fill quickly too.

So how often?

Twice a year, spring and fall, suits most homes, which is why The Loop offers a two-clean plan. Homes under heavy trees, with lots of glass, or where you want the windows clear all season do better on four cleans a year. Either way, we’ll tell you straight what yours needs.
