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.

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

For over a decade Ive 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. Weve 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!

We recently changed all our old windows to flush ones with SCI and couldn't be more pleased. They were by far the best value for money, their service has been fantastic and the quality is exceptional. They look great too, just like wooden windows. Highly recommend!

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.
