Sash window overhauls in Harrow

When too much repair work is needed, it’s no longer cost effective. In this instance, a sash window overhaul may be required. This will usually involve replacing your sashes or the full box frame, depending on their condition and what will produce the best results.

When we replace sash windows, we consult closely with you, ensuring we can design windows that are the right aesthetic for your property. Most customers want their new windows to be replicas of the originals – we’ll work to preserve period features and keep your property’s character at all costs. We can also work within conservation areas, such as Harrow on the Hill Village, South Hill Avenue, Waxwell Lane and Moss Lane.

You can enjoy benefits like modern window technology, excellent security and superior insulation. Choose double glazing or a glass upgrade:


Acoustic Glass

this reduces noise inside your property and is perfect for busy areas of Harrow such as Greenhill Way, Lowlands Road and Harrow Road.


Safety Glass

if you’re replacing sash windows in a commercial property, safety glass could benefit you. This is harder to break – if it does get broken, it won’t shatter.
