Fabulous product and service

SPS were professional and a pleasure to deal with from start to finish. Simon made sure every detail was perfect. They replaced a bay and two other windows in my house built in 1875 where nothing was straight but they made the windows to fit perfectly and totally in keeping with the original Victorian style. While the Accoya wasn’t cheap (I did have a much higher quote from another company) it is worth every penny for the quality, durability and sustainability. They also installed new French doors into the garden which look fabulous. The installation team were polite, clean and tidy and did everything possible to minimise disruption throughout. They were recommended to me and I would certainly recommend them and will use them again when I get other windows replaced.

Replacement of front door and 14 windows
Final Phase now completed hence the time lag. SPS have done a brilliant job although by no means the cheapest but you get what you pay for. They open and close like the door of an expensive car. They are painted in the factory so once fitted they can be used instantly. For our bay window they installed a screen to prevent the dust going all over the room. All windows were removed from this Victorian house without damage to the plasterwork. This also applied to the front door which was very impressive. Once the screen was removed all wood dust etc is taken off site and the room is immediately ready to use. The best workmanship I have come across in many years. A great team effort. Many thanks

We were so impressed with Simon and the team at SPS, and with the high quality of the double-glazed French door and window replacements they installed last year, that we called them back to replace the rest of the windows in the house. The remit was to recreate the same Victorian style as the originals, which they achieved down to the finest detail – including the shade and patina of inset coloured glass. The quality of workmanship was meticulous and finished to the highest standard, nothing was too much trouble and any problems that arose were resolved without fuss. We are delighted with the end result, which came in on schedule and on budget. The team was cheerful, tidy, and made huge efforts to minimise the disruption during the installation process. Not cheap, but certainly worth the expense. Highly recommend.

Fabulous accoya windows. Not cheap but will outlast me by a number of decades. Very clever way of incorporating the required trickle ventilation without a hideous trickle vent. Love them. Wish they were a bit cheaper and I'd get our bay windows done as well...But as others have stated, you get what you pay for....

We have just had our windows replaced by SPS. This was a complicated job, involving large, curved glass windows and tricky access via a shared scaffold. We are delighted with the finished windows, which look lovely and are beautifully made from accoya. The SPS team have been professional, patient, courteous and conscientious at all times, and a pleasure to deal with. They clearly take pride in what they do. It was very expensive but, given the nature of the job, somewhat inevitable. I have no hesitation recommending SPS to others.

Great quality sash windows

I’m very happy with my new windows. They look great and have helped reduce my heating bills and noise from outside. I started the process of replacing windows in 2020 and did this in three stages… finally completing them last week. Fitters were very tidy and friendly and communication from SPS has always been good. I also liked the idea of using Accoya wood as sustainable and very durable. The company was recommended to me by a friend and I’d recommend them too.

New Casement windows fitted by SPS - thoroughly recommended

We have just had all the windows at the front of our house replaced - two casement windows and one oriel. We are extremely happy with the windows and would recommend SPS without reservations. The fitters, Bryan and Sacha, were excellent and SPS were very good at keeping us updated with the whole process, from when we first contacted them in May 2022 until the windows were fitted in Feb 2023.

Fantastic new French doors and windows

Thanks to SPS for a first class job in renewing two sets of French doors, a new window and more particularly restoring a lovely 1920 stained glass window pane which had warped in the original frame. The company were a delight to work with and extra thanks to the lovely installation team who took a great deal of care to not only fit the new units but to clear up and restore the external and internal surrounds. Expensive, but as ever you get what you pay for.

Beautiful sash window installation

We are thrilled with our stunning new double-glazed sash windows in our downstairs bay and upstairs bedroom - expertly installed by the highly professional team at SPS Timber Windows. We can highly recommend their excellent service from the initial quote and surveying, through to the window manufacture and installation by their skilled and meticulous fitters Kal and Sonny. The project went like clockwork to schedule, the team were polite and considerate and their workmanship was excellent with great attention to detail. They take great pride in their work and our rooms were left in excellent condition. We wouldn't hesitate in using this company again to replace more of our period windows and doors.

SPS window fitting - Excellent service

The process has been seamless, if rather long, but that was what was expected and precise information was provided about each stage and how long it would take. In the end the fitting was delayed by us due to other ongoing building activities. The work carried out has been quite excellent. The window fitting was not straight forward as this is a 110 year old house where no walls or floors are straight. They were professional, extremely tidy, unobtrusive, and did an exceptional job leaving beautiful looking windows with the surroundings finished to a very high standard. The SPS team made what could have been very disruptive week relatively seamless.
