Sash window repair in Harpenden

If you are looking at Draught Proofing in Harpenden, the timber is only half the decision. Around here it is garden city stock, Georgian market town frontages and commuter-belt detached housing, and that alone rules out anything bought by the pallet. moderate rainfall with cold inland frosts is the local complication, and frost damage to end grain and swelling on unbalanced-finished units is what it eventually causes. What you are paying for is sealing the perimeter without making the sash stiff to operate.

Nothing goes into manufacture until a surveyor has checked each opening on site. Give us the basics and you will have a written figure, not a range that moves later.

One thing that catches people out here: garden city areas carry design codes that restrict window style changes.

Harpenden questions

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.

Do you work in hardwood or softwood?

Both. Engineered hardwood is the default where movement or exposure is a concern, and slow-grown softwood is often the better value choice for painted work in sheltered positions. We will tell you which we would specify and why.

What guarantee do you provide?

Ten years on workmanship, covering manufacture and the factory-applied finish. Where we install, the installation is covered too. It is issued in writing with the handover paperwork.

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.

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.
