Frequently Asked Questions
Below you will find answers to the most common questions regarding our sash window repairs, restoration, and joinery services in London.
How much does sash window repair cost?
The cost varies greatly depending on the condition of the timber, whether new sills are needed, and if you are upgrading to double glazing. A simple repair and draught-proofing service will cost significantly less than a full heritage window replacement. We offer free, no-obligation quotes after a thorough inspection of your property.
Do I need planning permission to repair my windows?
In most cases, sympathetic repairs—such as splicing in new timber or re-puttying panes—do not require planning permission. However, if you live in a Conservation Area or a Grade II Listed Building and want to install double glazing or fully replace the windows, you will likely need consent. We always advise checking with your local London council, and we are happy to assist with providing architecturally correct specifications.
How long does window restoration take?
A standard sash window repair and draught-proofing service usually takes about 1 day per window. Full restoration and slimline double-glazing retrofits can take longer depending on the drying time of paints, epoxy resins, and the complexity of the period joinery.
Can my original period windows be double glazed?
Yes! We specialise in retrofitting Slimline Heritage Double Glazing into existing timber sash and casement frames. This gives you the energy efficiency of modern windows without altering the historic, elegant look of your home.
Does draught-proofing really make a difference?
Absolutely. Professional draught-proofing can reduce heat loss through your windows by up to 50%. It significantly lowers your energy bills, completely eliminates rattling sashes, and helps block out London street noise.
Do you provide a guarantee for your work?
Yes, we are fully insured and offer a comprehensive guarantee on all our joinery, repairs, and glazing work. As a FENSA-registered installer, you can rest assured that our installations meet the highest industry standards for quality and safety.
