Repair before replace

If the original timber is sound we keep it. It is cheaper and it is better.

Brush seal systems that stop movement without making the sash stiff.

Honest condition survey

Including telling you when a window is genuinely beyond saving.

Most work in a day

Draught proofing and cord renewal are usually same-day, room by room.

Frequently asked questions

What if the opening is out of square?

Most older openings are. The survey records the actual dimensions at several points and the unit is manufactured to suit, which is the main reason we survey rather than work from the sizes given over the phone.

Will the finish need maintaining?

A factory-applied microporous finish typically needs inspection every three to five years, sooner on exposed coastal elevations. Maintaining it is far cheaper than letting a coating fail and the timber take up water.

Do you take a deposit?

Not before the measured survey. A deposit is only requested once the survey is complete and you have approved the final schedule and price.

Is the timber certified?

All our stock is FSC certified and chain-of-custody documentation is supplied with the order, which most main contractors and specifiers now require for their records.

How long does a typical order take?

Most made-to-size orders run six to ten weeks from survey to delivery. Conservation and heavily detailed work can take longer, and we confirm the lead time in writing at quotation rather than leaving it open.

Do you deliver nationwide?

Yes, we deliver across England, Wales and Scotland. Delivery is priced into the quotation so there is no separate charge added later.

Can you work on a listed building?

Yes, and a significant share of our work is listed or conservation area. We can supply drawings and section details to support a listed building consent or planning application, though the consent itself remains the owner's responsibility.
