Excellent service. came out to us as we were close to finishing a property refurbishment, unfortunately we were not quite ready for the windows doing this was our fault completely. Not a problem For Chris without hesitation he arrange to call out the following morning and he and his colleague did an excellent job cleaning the windows and frames. I’d highly recommend.

C-thru is a great window cleaning service I’ve been using them for over a year as I heard great reports prior on them and they’ve been doing my windows and other cleaning services since and I highly recommend them.

All the boys are lovely and would help me with anything.

The value for the amount of work and the effort that goes is unbeatable and the business is well known and respected I wouldn’t use anyone else
