Repair sash window – fix or replace damaged sash cord
£120
Earl's Court, Greater London

Repair sash window – fix or replace damaged sash cord One of my sash windows still opens and closes, but the left-hand sash cord is damaged or detached, and the counterweight inside the frame may be stuck. The tension feels uneven when opening or closing. The work should require: Remove the interior staff bead (thin strip of wood on the left side holding the lower sash in place) Take out the bottom sash carefully — lift it slightly, tilt it forward, and rest it down Open the access pocket on the side of the window frame (small painted-over panel about 10–15 cm tall, held by one or two screws) Retrieve the counterweight and attach a new sash cord (cotton or waxed nylon) Thread the new cord over the pulley wheel, reattach it to the sash, and rebalance both sides The window and glass are intact; it just needs the cord mechanism repaired and adjusted. Please bring the cord and tools.

Sash window spring balance repair: I have a tilt-to-clean 1000x1300mm wooden spiral balance sash window from a 1990s building (SE16 5EE) that includes support bars to hold the window at an angle when tilted. The bottom half of the window was blown open into the tilt position in high winds a few weeks ago. I was able to rotate the sash back into the frame so it is vertical again. Now the left side is stuck open (about 4cm from the bottom) and won't slide up and down; the right side is fine. The tilt latches must have come undone to enable the wind to blow it open.

Fix Stiff Wooden Sash Window (Needs Lubrication and Light Repair)
£50
Newington, Greater London
29th Apr 2025
One of my sash windows has become increasingly stiff and difficult to open and close. The window can still move, but it’s sticking due to friction along the side tracks, possibly from paint buildup and wear. I need someone to: • Gently loosen the window if needed (without causing damage) • Lightly sand or clean the sliding tracks if necessary • Lubricate the sash tracks (preferably with a dry silicone spray, not oil-based lubricants) • Check the sash cords for basic condition (no need for a full replacement unless necessary) • Make sure the window slides smoothly again without excessive force Important: • No heavy force or removal of the window needed — it still moves. • Please bring your own tools and materials (fine sandpaper, silicone spray, etc.) • Care needs to be taken not to damage the paintwork unnecessarily.
Ed did a fantastic job fixing the sash window pulley system. He was efficient, knowledgeable, and went above and beyond to make sure the problem was fully resolved. His attention to detail and willingness to go the extra mile really stood out. Highly recommend his services!

I'd like to install three sets of locking secure stops across two sash windows. I have one set of two installed previously, meaning the bottom sash in one room can only be lifted about 15cm. I'd like to do the same to the top sash of the same window . I'd then also like to install four more stops to get another window to the same state, where both the top and the bottom sash can only be moved by 15cm
Fix 2 sash window stops to window frame.

I have bought 2 bronze barrel-style window stops to replace old ones, which now need screwing into a sash window frame. It should be straightforward. You can see from the photos we had to remove old ones because we lost the key so the new holes will go under the circles you see in the photos. It should involve drilling 2 holes and screwing the barrels into the frame so that the stopper can prevent the window from opening past a certain point. I’ve also included a photo of another window to show you what it will look like when complete. Thanks
Ismael was very prompt and managed the job quickly and efficiently. Very friendly.
