High quality windows

SPS was recommended by our neighbour, who had used them for their own windows and were very pleased. We are pleased we went with them as we live in a conservation area and they were able to match the intricate lead and even offer stained glass options, including roundels, which most companies could not. They were also reasonably priced given the quality (good u-value and materials). Simon was very knowledgeable and responsive about the products and different options. The lead time to manufacture ended up less than expected, which was great. It is important to specify width of architrave, lead, mouldings etc. as they can match them and they offer you the chance to check over those details before manufacture. The windows are warm, smooth and elegant. In summary, we also highly recommend them!

Lovely modern sash windows, in keeping with the original Edwardian design
Customer Service

We had the original, single glazed sash windows replaced with the SPS Timber Windows A-rated double glazed windows with the modern in laid draught proofing system. The result, apart from the great look and feel, is noticeably warmer rooms and no condensation on the panes. Simon and his team replaced the frames as well as the windows, but the making good has been excellent and means a consistent design right through the house. The windows are not cheap, but worth if you have a traditional property where plastic would be an inferior option.

EXCEPTIONAL WORK
Customer Service

We are absolutely delighted with the work that Simon and his crew did in installing new windows throughout our house and also new patio doors. The Edwardian period features were closely replicated and the windows, installation and paintwork were of exceptionally quality. Considerable care was taken to minimise the spread of dust and disturbance to surrounding structures and to make good where necessary. The work was done as closely to schedule as the weather allowed and to cost. Simon and his crew were all pleasant and considerate - it was almost a shame to see them leave! The end result of their efforts has been to greatly improve the appearance and functionality of our house and also make it much warmer.

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.

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.
