PVCu Windows

Our PVCu windows combine energy efficiency with low maintenance, designed to meet UK climate demands. Available in multiple styles, they enhance thermal insulation while preserving architectural aesthetics. Backed by a 10-year guarantee, these windows reduce energy bills and carbon footprints through A-rated double glazing.

Bi-Fold Doors

Bi-fold doors create seamless transitions between indoor and outdoor spaces. Crafted from durable materials, they offer sleek contemporary designs with smooth operation. Customisable to fit various property types, these doors prioritise security without compromising on style or functionality.

Composite Doors

Composite doors provide enhanced security and thermal performance with a choice of finishes. Reinforced frames and multi-point locking systems ensure durability, while custom designs maintain visual appeal. Ideal for improving kerb appeal and property value with minimal maintenance requirements.

Sash Windows

Traditional sash windows replicate period features while incorporating modern double glazing. Suitable for conservation areas, they balance authenticity with improved energy efficiency. The heritage designs maintain property character while meeting current building regulations.

Roof Lanterns

Roof lanterns flood interiors with natural light, ideal for loft extensions and open-plan spaces. Thermally efficient glazing options reduce heat loss while maximising brightness. Custom designs ensure structural integrity and aesthetic coherence with existing architecture.

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,

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!

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!
