I was looking for someone local who could supply and install Flush casement windows. After meeting with a few suppliers and checking reviews, I chose to go with Sanderstead Windows. Colin recommended Residence 7 windows, which really look the part. In total Colin installed 9 Windows and a back door, spread over around a year as we worked through a big renovation. I’m really happy with how the job went, the Windows look fantastic, and Colin was flexible and easy to deal with. Highly recommended.
Colin and Aca done a fantastic job. said they was going to be here at 07:30am and they was bang on time, also said the windows was going to be fully fitter within one day, they done by folding doors with blinds in and out all within one day. Very impressed with the workmanship even in the rain, the doors turned out far better than we thought. No decorating needed inside, perfect fit. Fantastic job top marks to the guys.
