Double glazing designed around your property
Every home has different requirements when replacing its windows. The size of the openings, the age of the property and the preferred appearance all influence the most suitable solution. Advanced Glazing Systems offers a range of window styles, including casement, flush sash, sliding sash, bay and tilt and turn windows.For properties where maintaining traditional character is important, flush sash and sliding sash windows provide a classic appearance with the benefits of modern double glazing. For homeowners looking for a more contemporary finish, aluminium windows offer slim frames, clean lines and a wide choice of colours.uPVC windows provide a practical option for homeowners looking for durability and low maintenance, while still offering flexibility in terms of style and finish. The team can advise on the different materials and specifications available to help you choose windows that suit your home.Advanced Glazing Systems offers A-rated double glazing as standard, with A 12 and triple glazing options available where additional thermal performance is required. All windows are made to measure, professionally installed and supported by a 10-year guarantee.
Finding the right fit for Brentwood homes
Brentwood properties vary considerably in design, with Victorian and Edwardian homes, traditional detached houses and modern family developments all found throughout the area. This variety means replacement windows need to be considered carefully to achieve a result that feels natural.Older properties often benefit from window styles that reflect their original proportions. Flush sash and sliding sash windows can help maintain a heritage-inspired appearance while providing modern levels of security and insulation.For newer homes, extensions or homeowners wanting a cleaner look, casement and aluminium windows provide greater flexibility. The choice of colour and finish can help tie the new windows into the wider appearance of the property.
A practical upgrade for everyday living
Replacement windows are often an investment in the overall comfort of your home. Modern glazing can help create a warmer environment, reduce draughts and provide improved security compared with older window systems.Advanced Glazing Systems helps homeowners consider the different options available, from frame materials and window styles to glazing performance. This allows the final installation to reflect the needs of the property rather than relying on a standard approach.Whether you are replacing a small number of windows or upgrading your whole home, the right specification can help create a more comfortable and practical living space.

Great service from Start to finish.
After looking around for a while I made the great decision and chose AGS.
From the start Tyler was very professional and helpful on the phone, he sent me pictures by email of doors in the colours I was thinking about and also pictures of the fixtures and fittings so I could compare colours.
Tyler was very communicative throughout the whole process. On the day of installation the fitter was punctual and polite and clearly knew his stuff, door is working a dream. Especially happy with the making good and how he installed the trim, such a clean and tidy finish.
