Consumer feedback

Generated from the text of this trader's consumer reviews

Advanced Glazing Systems Ltd (AGS) comes across as a genuinely people-led, family-run glazing team, with customers praising everything from the first meeting through to the finished installation. Multiple reviews highlight smooth, well-managed projects—whether supplying heritage uPVC windows and doors for conversions, fitting bay windows, or installing secure front and back doors—backed by professional, friendly communication from the office and attentive installers. Names that come up often include Tyler in the office (called “brilliant”, “friendly and reassuring” and “very knowledgeable”), plus fitters such as Ryan & John, and Steve, with installers consistently described as punctual, tidy and careful around surrounding structures.

What Customers Say

Excellent communication & customer care: Reviewers repeatedly mention being kept informed “throughout”, with the office team welcoming questions and support that feels “no hard selling” and reassuring from the start.
Punctual, tidy installations: Fitters are described as “polite and professional”, arriving on time, working hard all day, and leaving drives and surrounding areas clean—sometimes removing old doors “without any damage”.
Quality products & honest value: Customers say doors and windows are “of an excellent quality”, with pricing described as “honest” and “competitive”, and in at least one case praised for a “10 year warranty”.
Tailored advice for real needs: Tyler is specifically credited for understanding individual requirements, including support for disabled access and even guidance on key/locking usability.
