Double Glazed Bay Windows

In and Around Trowbridge, Melksham & Bath

From our founding in 1995, we have built a strong reputation by delivering reliable service and maintaining an unwavering dedication to the needs of our customers.

Our double glazed bay windows are built to keep the heat where it should be, so you stay cooler in summer and warmer in winter. They carry the highest possible rating from the British Fenestration Rating Council, making them one of the best ways to bring your energy bills down.

A C-rated window might be the legal minimum, but it’s not going to save you money on heating your home in the long run. With extra quality in mind, we only supply A+ and A++ rated glazing because we think if a jobs worth doing, it’s worth doing properly.

That’s the real benefit we see in using A-rated double glazing and once our team has it fitted, you’ll notice the difference straight away. Come brighter days, your bay windows give you brilliant airflow, and you’ll be able to enjoy beams of natural light throughout the day.

We cover our local SN12 postcode area, the city of Bath (BA1 & BA2) as well as nearby towns like Bradford-on-Avon (BA15), Trowbridge (BA14), Westbury (BA13), Warminster (BA12), Chippenham (SN14), Devizes (SN10), Marlborough (SN8), Royal Wootton Bassett (SN4), Calne (SN11), and the surrounding countryside.

Bay Window Replacements

in Trowbridge, Melksham & Chippenham

With bay windows, it’s often the frame or casing that shows the first signs of wear. Once that starts to happen, you’ll notice it looks worse, frequent cold draughts and some water will creep into the windowsill and wall around the bay.

This is the last thing you want with such a central feature of your home.

If your bay windows are starting to look tired, or single-glazed bays are letting the heat escape, you should consider an upgrade. At Alan Joy Windows, we’ll fit new double glazed bay windows that are far easier to look after, better for your energy bills and more secure.

Our team knows that replacing a bay window is a bigger job than a standard window. With 30+ years of experience fitting new bay windows across Wiltshire, we’re well placed to give you any advice with the right choice for your home.
