Fitted new double glazed windows to front of house. Excellent price and workmanship from SCI. Efficient from initial approach from Neal the owner to completed work. The fitters Chris, Harry and Tony worked hard, were polite and cleaned up after completion. Highly recommend this company. Attached photo of how they copied the original coloured leaded glass of a 1920s house in Merton Park,

We used SCI 20 years ago and it's testament to the service they provide that they are still going strong now. We needed the whole house to have replacement windows and doors and remembering the great service we received 20 years ago called SCI in the hope they would come out to us since we moved to West Sussex from Surrey. Neal came out for a quote and there was no 'sell' like what we had from Zenith 20 years ago (4 hour sales pitch).
Quote arrived a few days later and without hesitation we accepted and Neal came back out to measure up. SCI kept us informed along the way and the day arrived for install. The 2 guys arrived on day 1 where absolutely amazing (Tony & Dean) and explained everything. They sheeted up and made us aware of everything that was being done. The care to our property was their priority and they upmost professionals.
They had a few issues beyond their control but made every effort to correct this keeping us informed along the way. Day 1 was cut short as more materials were needed but on day 2, they came in force with a couple of extra guys that fitted the back and front door leaving Tony and Dean to concentrate on the windows. Again, the extra guys where so lovely, even correcting a loose blind - way above levels of customer service.
Day 3 (today), Tony & Dean finished the bi-fold doors and front window, along the way they have explained everything, made sure our home was kept tidy and clean and just been all round nice people. Tony is an absolute professional and has genuine pride in his work and Dean is a diamond. I cannot recommend SCI highly enough to anyone that is looking to replace doors or windows. Neal, your team is awesome and we thank you for just the best service and customer experience - massive thumbs up to SCI!

For over a decade I've used SCI - both at work and at home. The after sales service is just stunningly brilliant. They also quote without all the silly games and really understand what you need before just fitting what they think you want. They made some excellent recommendations 10 years ago on my house - and still the windows are perfect. We've had a couple of return trips for support where we went against their advice and got uPVC bi-folds. they were right, we should have spent more on decent ones! A brilliant local company.

SCI replaced nearly every window in our house at a competitive price. Pleased to say that the installation went smoothly (fitters were punctual and left the house as clean as they found it) and there were absolutely no issues. Visitors to the house have complemented the look so we are very impressed. Well done to Neal and team!

Fantastic company, had a composite front door and side window fitted by them. Competitive price, no crafty or pushy sale tactics, whole process was easy from start to finish and the new door looks and functions great! Have happily recommended SCI to friends, family and would recommend to others. Will use again in the future for any window and door needs.

We had all windows, two doors and a custom designed stained glass unit installed by SCI. The whole team was extremely helpful from start to finish, and the quality of the work carried out is fabulous. In addition to the standard windows and doors we ordered, I designed my own complex stained glass unit for one of the windows. The end product is nothing short of stunning.
The workmanship is fantastic and the finished item matches my design to a tee. Prices were very reasonable, and sales people right through to the installation team were helpful, neat and friendly. I wouldn't hesitate to recommend SCI for any job - small or large.

We used SCI to supply and install our new bifold doors as well as front door and had absolutely no hassles with them. Neal and the team were a pleasure to work with and invited us to their showroom to review the details of the quote and explain everything very clearly. Our builders were also very impressed with their quick and clean installation. Can only highly recommend them and SCI will always be my first point of contact if I need anything window or door related.

Fantastic service from the SCI team. Great consultations from the very friendly Neal giving us lots of opportunity locally to see their work. Gave good advice to pick the right product. Delivered on time and did a great fitting job. Hardly any 'making good' required and even dealt with removing and refitting our shutters without a hitch. Highly recommended.
