Beautiful, bespoke joinery from Wandsworth Sash Windows

We offer a wide range of services to repair and refurbish windows, as well as replacing them in full. We are specialists in timber and fully appreciate its natural beauty, helping you make the most of your property’s charm, character and period features. We’re highly experienced joiners and carpenters, with the skills needed to look after all timber windows, while at the same time using the latest technology to improve insulation and security.

We can also upgrade your glazing to bring further benefits – these are the two options we have available:


Acoustic Glass

this can reduce noise by 1dB for every 1mm of glass. This is important, as noise over 45dB can affect sleep, but the average noise level on a London street is 60dB. For this reason, acoustic glass is popular with our customers in South London, especially those living and working in busy areas such as Dulwich, Clapham and Vauxhall.


Safety Glass

choose from laminated glass or toughened glass, neither of which will shatter if broken. Toughened glass is harder to break and is a popular option for commercial buildings.

Please note, we can only install acoustic glazing when we completely replace your windows. This is to make sure the frame will accommodate the thicker glass.

Sash window replacements in South London

Some sash windows will need to be replaced, especially if they’re older and haven’t been upgraded. We’ll make and install your new sash windows ourselves so they’ll be the perfect fit for your property. We can ensure they look exactly the same as the originals to keep your property’s character, and so that they blend in with your other windows if they don’t all need replacing.

New sash windows benefit you because:

  • They’re beautiful yet traditional – a new and improved version of your current windows
  • They have excellent insulation – modern window technology is advanced and we offer double glazing as standard
  • They’re better soundproofed – enjoy a quieter life with new windows (even more so if you choose acoustic glass)
  • They can improve the value of your property – beautiful, well maintained windows help boost property prices
