Top Job

Windows had not been done for a long time and now are better than they have ever looked. Very reliable and honest, would highly recommend to all.

First Class Service

I was so pleased with the work carried out on my conservatory that I asked them to clean the internal communal area windows in the supported housing scheme that I manage. Thank you for a first class and reliable service.

Very Happy!

C-Thru have cleaned my windows for the first time and I can honestly say they have never looked better. Will most certainly be asking them to do them monthly!
