What we do and how we do it

What makes Sash Window Restoration work in the UK is usually invisible once it is finished. You will find mostly a mix of period and modern stock in this area, and it moves as it ages. With the full range of UK exposure conditions in the mix, coating failure followed by rot at the joints is a question of when rather than whether. In practice that means taking the window back to sound timber before anything is recoated.

Nothing goes into manufacture until a surveyor has checked each opening on site. One call is usually enough for us to tell you roughly where the price will land.

A local consideration we always raise: specification should always be matched to local exposure.

Specification

  • Engineered hardwood or slow-grown softwood, FSC certified
  • Factory-applied microporous finish in any RAL or heritage colour
  • Sealed units, slim-cavity units or single glazing with putty line
  • Manufactured to survey dimensions, not to a stock size chart
  • Delivered UK-wide with chain-of-custody paperwork

Repair before replace

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

Draughts and rattle gone

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.

What happens next

Four steps from first call to installed joinery. No pressure at any stage.

  1. Condition survey

    We assess each window and tell you what is worth doing.

  2. Itemised quote

    Priced per window so you can phase the work if you want to.

  3. Repair and seal

    Cords, weights, splices and brush seals, mostly done in situ.

  4. Decoration

    Prepared and recoated so the repair actually lasts.

Frequently asked questions

Can you price from drawings?

Yes. Send a drawing set or a schedule and we will price against it. If anything is ambiguous we will query it before quoting rather than assume and reprice 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.

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.

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.

How do you handle glazing?

Standard double glazed units for most work, and slim-cavity units where a conservation officer has restricted sightlines. Single glazing with putty lines is available where the consent requires it.

Do you fit, or supply only?

Both. Supply-only is common for trade and contractor clients. For private clients we usually recommend supply and fit, because responsibility for the fit and the finish then sits in one place.

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.
