Do you replace the whole bay, including the corner posts?

Normally, yes: the bay is made to measure as one set of frames with matching corner posts. At survey we check the bay's structure, roof and cills, and tell you if anything else needs attention before we quote.

Will the bars and horns match the other windows?

Yes. The bay is specified with the rest of the elevation, so bar patterns, horns, rail depths and colours carry across the house.

Are bay sashes as secure as the other windows?

They have the same security: key-locking cam locks, toughened glass, an anti-jemmy bar in the cill and key-operated restrictors on every opening sash.

Five-Part Bay

Deeper bays for larger rooms.

Five lights forming a deeper, rounder bay for larger rooms and grander houses. Every light is a working sash unless you choose to fix one, and every one tilts in for cleaning.

Our Approach

Replacing a bay properly.

Surveyed face by face

Each light of the bay is measured individually, along with the angles between them.

Structure checked

We look at the bay roof, the cill and the corner posts before quoting, and tell you about anything we find.

Matched details

Bars line through from light to light, and horns, rails and colour match the rest of the house.

FAQs

Sash bay windows: your questions answered.

Yes. Each light in the bay can be a sliding sash. The centre sash can also be fixed if you'd rather have an uninterrupted view, with the side sashes providing ventilation.
