Sash Window Replacement Earlsfield South West London

Sash window replacement

We offer a unique service where a lot of people would love to upgrade their windows to double glazing but cant for conservation reasons, we have system where you keep your original frames and we insert new sashes in them keeping the section sizes the same with double glazing installed. It’s a way to keep your original aesthetics and benefit from double glazing and draught proofing. We call this a “retro fit”. we usually recommend a reasonably priced hardwood sash to replace the common softwood sash as with experience we find softwood sashes deteriorate rapidly compared to hardwood.

Draft Proofing Earlsfield South West London

Draught proofing sash windows

Draught proofing your sash windows is a great way to stop the common “whistling window” when its rattling in the wind and letting cold air into your property. We don’t use the reasoning that your initial investment would be returned in saving on your heating bills as the numbers just simply don’t add up! However, if you want a warm cosy home with reduced bills then this is a great option to think about. We can guarantee draft proofing sash and casement windows and doors up to 95% from its original state so it really is worth while.

Window Overhaul Earlsfield South West London

The window overhaul

In this system, we’ll re-cord your sashes, free off the sashes and pulleys or replace the pulleys where needed. Upgrade and replace the staff and parting bead. Counter balance the sashes to the weights to get them functioning properly and fill any minor defects/glazing putty ready for decoration to be done by your own decorator. Decoration is not included in this service.

Full Window Refurbishment Earlsfield South West London

The full window refurbishment

In this system we aim to bring your window completely back to life! As the window will probably be as old as us both put together we cant guarantee it’ll look completely brand new, but we can try to get it as near as dam it!
What we do is take the window apart completely, removing the catches firstly and see if we need to change or re use (depending on the property/customer preference) we’ll then assess the sashes for rot and splice/make good where needed, we’ll then go to work on the box, freeing off the pulleys. Removing the weights and generally cleaning it up, filling it, assessing the sill, pulley styles and linings getting it ready for recoating, we’ll prime,undercoat and top coat your windows using the zinsser paint system.
Once coated we’ll then fit new beads all round, new cords, catches, re-weight and draught proof, once this is done and the window is back together working, we’ll then apply another top coat to try and achieve a perfect finish!
Using this option it’s a one stop shop for everything which takes the hassle out of having to find any other trades to finish it off.

Mark manufactured and installed the windows in my farm house. They had to be changed like for like as we live in a conservation area, when the windows arrived at our house I was amazed how every little profile matched the ones we were taking out. Definitely would recommend.
