An excellent company, prompt, professional and clean. No over the top sales jargon, their straight price given was price paid. Not pushy. Workmanship great, any minor faults found by the company and rectified straight away. Extremely tidy workers and finished within estimated time. Would certainly recommend 100%.

My wife and I have had new windows and doors supplied by John and his excellent team over the last few days. The service has been exceptional from start to finish. John attended and gave a very competitive quote compare with 3 other local and national companies. No lengthy sales pitch or discounts if you sign up now, just honest and competitive quote with no pressure. The products were made and fitted within 3 weeks. They are of excellent quality. Darren and Adam the fitters were the most friendly and helpful tradesmen we have ever used. They are prompt, tidy and highly skilled professionals. We are so please as other trades people have often disappointed. Advanced Glazing Systems Ltd did not disappoint. Kind Regards Andy and Jan
