We are very happy with the job. The new windows look great and have opened up the view from so many of the rooms. The stained glass window has cleaned up nicely and looks particularly well. Billy and Rodney worked very hard and did a great job and kept the disruption to a minimum and cleared up all of the dust and dirt from taking the old windows out.

Thanks for all your attention to detail. We are thoroughly delighted with our new look bungalow!! Billy and Rodney your 2 fitters were amazing lads at their work. We would certainly recommend Complete Window Systems.

A huge thank you to Hilary and his team for fitting our new front door. It looks fantastic, inside and out. His team was professional from ordering to fitting. Would recommend to anyone thinking of new windows and doors.

CWS completed our home’s transformation from double glazing to triple glazed windows and doors and we are immensely pleased with the results. The fitters were perfectionists, tidy and well experienced tradesmen and we are delighted with our new install. Thank you Hilary and team.

The guys were top class and finished to a quality beyond my expectations but to my delight. One example was that the second thing I was asked was “where is the vacuum” and that was well used. the guys were a pleasure to work along with, always busy busy, but always very friendly. The choice of Windows and especially the front door have been very suitable and the house now has a smile in its face.


Very professional job. Fitters were great no mess whatsoever. Would highly recommend Complete Window Systems. Love my new front door.
