FAQs: heritage sash windows in Hitchin

Do I need permission for sash window replacement in a conservation area?

It depends on your property and proposed changes. Like-for-like timber replacements often have a smoother path, while double glazing or altered profiles may require approval. We can prepare drawings/specifications and coordinate with your professional team. Always check with the local authority before works.

Can you fit double glazing in traditional sashes?

In many cases, yes—using slimline heritage units designed to protect traditional sightlines. Suitability depends on frame thickness, glazing bar design and conservation guidance. We’ll advise at survey stage.

What timbers do you use?

We select durable, properly seasoned timbers appropriate to the application and finish. We’ll recommend options during the quotation to balance longevity, maintenance and budget.

How long does an installation take?

Most restorations complete within a few days per elevation; full replacements vary with scope. We’ll provide a clear programme with your quotation.

Will the work be messy?

We use dust extraction, floor protection and daily tidy-downs to keep your home liveable throughout the works.
