How often
Most homes suit a clean every four to eight weeks. Houses on main roads, near the coast or under trees tend to need it at the shorter end. Adam does rounds every second week or monthly, and one-off cleans.
Why it matters
Dirt on glass is mostly traffic film, pollen and dust stuck on by rain. It builds up in layers, so each clean you skip makes the next one harder.
Frames and sills hold the worst of it. Left alone, green and black growth settles into the seals and corners, where it is slow to shift.
Upstairs windows are the ones most people cannot reach safely themselves.

Do you clean the frames and sills as well?
Yes. Frames and sills are wiped down along with the glass.
Do I need to be home?
Mention any side gates or dogs when you book.
Why do windows streak again after a shower of rain?
Usually because dirt on the frames and sills runs back down onto the glass. Cleaning the frames and sills along with the glass cuts that down.
Can you clean windows and gutters on the same visit?
