Sash Window FAQs

What Are Sash Cords?

Sash cords, sometimes referred to as sash ropes are a vital part of the sash window design which enables the window to operate properly. When these cords break, the windows may no longer be opened or closed.

If you’re experiencing faults with your windows operation, it could be that the sash cord is broken or worn, get in touch with us today to book a home visit.

How Much Does a Sash Window Repair Cost?

The cost of the repair or refurbishment of your sash window depends on several factors including age, style, accessibility and current condition.

At Novells, we don’t believe in hidden costs or surprise bills, that’s why we provide a free estimate to give you an idea of expected costs before work goes ahead.

Can I Repair My Own Sash Windows?

When it comes to sash window repair, some homeowners do opt for a DIY approach. However, without the proper expertise, this can do more damage and good to the window which is why we highly recommend using a professional unless you have the proper tools and knowledge to do it safely on your own.
