They guided us through the decision making process and accommodated a last minute change to the specification which made all the difference to the end result. Their fitting team were excellent - professional, integrated their work plan with the main contractor and delivered a high quality finish. Would highly recommend SPS." > — Customer in Greater London (5.0, via Which? Trusted Traders) > "We recently had timber casement windows fitted at our period property and we are delighted with the results. Simon, Richard and the team give you great confidence in the quality of the product and the finish. They started on the agreed date and finished on the agreed date. The installer (Nad) did a great job and checked in with us regularly to make sure we were happy with all aspects of the work. Highly recommended." > — Customer in Surrey (5.0, via Which? Trusted Traders) > "Due to workload, we had to wait a little while for our new bay windows and I cannot tell you how happy we are with the finished product. From the early stages - measurement, drawings and design, through to the installation and finish - we've been very impressed with the company, their team and the information given. Everything, every stage went according to the schedule agreed and laid out. We were particularly impressed with the fitter Nad. He's clearly a highly skilled fitter with a meticulous approach to his work. He was professional, punctual, with tremendous attention to detail as well as being courteous and pleasant at all times. At the end of each day, everything was left clean and tidy. The company was highly recommended to us by a friend so we were able to see at first hand the work the company had done for them. We too would not hesitate in recommending SPS Timber Windows Ltd in future." > — Andrew & Audrey in Greater London (5.0, via Which?
