It’s an excellent product, extremely resistant to weathering and fading What’s more, it’s produced as a fully colour-matched suite including doors, window panels and conservatory roofs. Not all whites are the same, and it’s easy to end up with an irritating colour mismatch when installers use one type of moulding for the doors and windows, and then a complete roof, from another manufacturer. The Synseal system ensures that everything matches exactly.


Synergy offers a full range of sliding sash windows, and can provide suitable replacements for most ages and styles of house. They also offer leaded, bevelled and coloured glazing options, and there’s a service for the replacement of period coloured glazing, using a specialist expert contractor to produce hand-crafted replacements matched as closely as possible to the original colours. There’s also an extensive range of composite woodgrain doors, which have become very popular in recent years for their security, attractive appearance and wide selection of colours.


There’s a full project management service from design to completion, including any planning implications. When it comes to conservatories and garden rooms, plumbing, flooring, electrics, and heating & cooling systems can all be installed,


So what makes Synergy special? “We’re a family firm first and foremost,”. “We don’t employ high-pressure salesmen, and we don’t pay out huge commissions or enormous advertising costs, so we can compete well on price as well as quality. And buying from an established local company means we’re on your doorstep if you need us - you get to talk to the same people every time, and it’s easy to get after-sales support if you need it.” The company is a registered FENSA installer, and its guarantees are backed by GGF (the Glass and Glazing Federation), offering further peace of mind for its customers.
