When homeowners in Grand Rapids think about window cleaning, they usually picture the outside of the glass — the side that faces rain, pollen, and Michigan’s unpredictable weather. But what about the inside? Interior and exterior window cleaning serve different purposes, and getting both done makes a bigger difference than you might expect.
What Makes Exterior Windows Dirty?
Your exterior windows take the brunt of everything Mother Nature throws at them. In West Michigan, that means hard water deposits from sprinklers, pollen in spring, dust and dirt kicked up from nearby roads, bird droppings, and mineral buildup from rain. Over time, these contaminants bond to the glass and become harder to remove with a simple garden hose.
At Moonwalker Window Cleaning, we use water fed pole technology to clean exterior windows safely from the ground. Pure, deionized water dissolves dirt and minerals without chemicals or detergents — and because no ladders ever touch your home, there’s zero risk of damage to your siding, gutters, or landscaping.
What About the Inside?
Interior windows collect a different kind of grime. Cooking residue, fingerprints, pet nose prints, dust, and condensation all leave films on the inside of your glass. If you’ve ever noticed your windows look hazy even after the outside was cleaned, the interior is usually the culprit.
Interior cleaning also gives us a chance to inspect your window seals, screens, and tracks. Catching a failing seal early can save you hundreds on replacement costs down the road.
Do You Really Need Both?
Short answer: yes, if you want the full effect. Cleaning only the exterior is like washing the outside of your car but leaving the inside covered in dust — you’ll notice the difference immediately. When both sides are clean, natural light floods in, rooms feel brighter, and your home looks sharper from the street.
That said, exterior windows typically need cleaning more frequently than interior ones. Many of our Grand Rapids customers do exterior cleaning every 4–8 weeks during the season and add interior cleaning once or twice a year — usually in spring and fall.
How We Handle Both at Moonwalker
For exteriors, our water fed pole system reaches up to three stories from the ground. Pure water does the heavy lifting — no soaps, no squeegees leaving streaks, no ladders leaning against your house. We use a small 4-foot A-frame ladder for ground-level access only, but nothing ever touches your home or building.
For interiors, we work carefully around your furniture, curtains, and belongings. We clean the glass, wipe down frames and sills, and make sure everything is spotless before we move on.
The Bottom Line
If you’re investing in professional window cleaning, doing both interior and exterior gives you the best return. Your windows will look their absolute best, your home will feel brighter, and you’ll extend the life of your glass and seals.
