Windows Store Ltd
Timber and aluminium, made in London
Surveyed, built and fitted by the same small team, across every borough inside the M25.
What sets us apart
Most window firms stopped using putty. We didn't.
Linseed oil putty is bedded by hand, knifed to a clean bevel, and then left to skin before it can be painted. A pinned timber bead takes minutes and needs no waiting. That is the whole reason most of the trade moved away from putty — not because the bead is better, but because it is quicker.
It is also why other window companies bring their heritage work to us. A homeowner may not spot the difference between a putty line and a bead. A conservation officer does, and so does the firm that has just been asked to match one.

Who does the work
A small team, and no one else
The person who measures your windows works with the people who build them and the people who fit them. Nothing is passed to a subcontractor along the way, which means there is no point in the job where nobody is quite sure who is responsible.
