Sash window repairs London – we offer great tips on who to trust, and if your keen on DIY how to do it yourself. Firstly it’s important to understand the condition of your windows. If we cannot diagnose the problem, we cannot fit it! Above is an example of a window that requires sash window repairs.
Being an experienced sash window specialist this diagnosis would be easy. To bring this sash window up to good structural standards would require a sill front with a splice on the front cheek and stiles. We can see on the left hand side the parting bead has been broken off and is missing down to the sill. This is highly likely that an amateur broke off the rotten section, filled and painted over. This is a huge warning sign for any sash window specialist because the new concern is what else has been covered up. The likely full extent of the damage is a new sill, new sash stiles, the lower sash will need re wedging and the joints glued with an epoxy resin. We will also need to remove the filler placed under the sill. This has been filled where rot once was and the installer did not thoroughly remove the rot and the consequences of doing a poor job can now been seen, probably just twelve months after the repairs! A great example of sash window refurbishment can be seen on this post.
Sash window repairs London specialists would gently take off the staff bead, remove the lower sash, cut the sill away splice out the stiles and then splice out the stiles at 90 degrees so that new fresh timber can be cut and attached neatly with a crisp bond. Normally sash window repairs of this nature will be carried out using Douglas Fir. It is quite likely that water ingress under the sill will have made the wall damp, and blown plaster internally. This must also be dried out, but before doing so it is wise to pour in some quality dry rot treatment. Theres a fair chance after repair spores will be left behind and this will be the start of the dreaded dry rot, which will not only damage window, but if left long enough can run through the wall and into the beams, literally destroying the home! Now don’t panic this is all treatable and takes a long time. The point is not to let this occur. If your concerned that your windows may be in this kind of condition it would be wise to contact a London sash window company expert to at least survey the issue as they’ll be able to indicate the viability or repairing or replacing your sash windows.
