Previous window cleaners were unreliable; they would turn up a couple of times and then disappear.
Timber is absolutely reliable, charges a fair price and does an excellent job.
All doors are cleaned as well as the glass. He also does inside cleaning on request and never leaves a mess. You can pay online very easily.
Timber is very pleasant to have around. I have recommended him to several neighbours and would have no hesitation in recommending him further.
