Frequently Asked Questions

Q: Do you replace sash windows or just restore them?

A: Whenever possible, we restore. Replacement is only recommended if the timber is beyond repair. Restoration preserves the character and value of your Cambridgeshire home.

Q: Can you make my sash windows more energy efficient?

A: Yes. Our draught-proofing systems, secondary glazing, and slimline double glazing significantly improve thermal performance while keeping the original appearance.

Q: How long does sash window restoration take?

A: A typical set of 4–6 windows takes 2–4 days for on-site restoration. Workshop restorations can take longer but deliver a perfect finish.

Q: Are you based in Cambridgeshire?

A: Yes. NJ Sash serves Cambridgeshire and surrounding counties. We’re local, responsive, and familiar with local conservation area rules.

Cambridgeshire has many conservation zones (e.g., Newnham, De Freville Avenue, Ely Cathedral Close). We are experienced in working within these areas and can advise on sympathetic sash window restoration that meets planning requirements.
