Clean windows change everything — brighter rooms, better views and a home that looks instantly cared for. Our trained technicians treat every pane by hand, removing dirt, pollen and hard water spots without leaving a single streak behind. Whether it’s a cozy bungalow or a large two-story home, we bring the same meticulous attention to every piece of glass.

FAQ

Common questions

Everything you might be wondering about window cleaning.

Yes. Our standard service covers both interior and exterior glass, plus screens, tracks and sills for a complete, finished look.
Most Pittsburgh homeowners book two cleanings a year — spring and fall. Homes near trees, pollen or busy roads often prefer quarterly service, which you can lock in with one of our membership plans.
Not at all. We use eco-conscious, biodegradable solutions that are safe around landscaping, pets and family.
Clean windows aren’t affected by normal rain — it’s dirt that causes spots, not water. Our membership plans also include a 7-day rain guarantee for added peace of mind.
For exterior-only cleanings, no. If interior windows are included, we’ll just need access. We’re always happy to work around your schedule.
