Interior vs Exterior Window Cleaning: What’s the Difference?
The Short Answer
Exterior cleaning handles the outside face of your windows — the side that gets rain, snow, dust, sap, and hardwater. Interior handles the inside — dust, kids fingerprints, cooking residue, and general household grime. Most homes need both, but exterior is usually the higher priority.
What Exterior Includes
Full pane wash, frames, sills, hardwater removal on affected panes, and (with the Alta Club) rain/snow repellent tech. Because outside glass gets the worst weather, it needs a real 4-step process — scrub, squeegee, rinse, detail — not just a fast wipe-down.
What Interior Includes
Every pane, the sill, and the window track (that is the horizontal channel at the bottom where dirt and dead bugs accumulate — nobody thinks to clean it). Streak-free finish is the whole game with interior — Utah sunlight is unforgiving of even one streak.
Why Bundling Saves You Time & Money
Once a crew is at your house set up with ladders and gear, adding interior on does not double the price — it usually adds a lot less. And you get it all done in one visit. Ask about combo pricing when you get your quote.
The Utah Homeowner Sweet Spot
For most Utah homes: exterior 3x a year (Spring, Summer, Fall — the Club schedule) + interior 1-2x a year around holidays or big life events (party, listing, family visit). That keeps windows looking great year-round without over-spending.
