The worst company I almost worked with. They came out for a free quotation and instead have invoiced 60 + 12 VAT. Would recommend everyone to avoid, poor service and hidden costs!

Thought we would use a local long established business and glad we did.we had several quotes from various companies for bi-folds, which included structural work and saje made the whole process hassle free and professional through planning, installation and aftercare, the owner even arrived to check the work and made sure we were happy with the finish.fantastic job from start to finish.

Superb company to deal with. I had my windows installed in 2002 and my windows look as good as they did 14 years ago. No hard sell salespeople, just good prices. I had a small issue after installation which was dealt with very quickly. I would use again without hesitation. Also, unlike others companies they don't change their company name every few years and are still a family owned company after all these years.
