Latest Reviews

  • Our second time working with the team at SCI. They deliver high quality products at a good price. Their workmen are on-time, polite, professional and tidy. They are booked out for months for a reason! Wouldn’t hesitate to recommend or use again.

    Ms O’Neill – Google Review

  • I don’t normally leave reviews but I had to because I think SCI really deserve one. They did an excellent job, did no damage and left the place spotless. They were also the cheapest quote of 4 for like-for-like product. After agreeing a price, I was called a few days later and they offered to replaced some rotten timber on the bottom of my 1st floor bay window for free. Very pleased over all from sales to installation. Also nice to support a small local company
