How to Repair Rotten Window Frames and Sashes

sliding sash window for repairI’m always up for repairing rather than replacing if it makes sense.  When it comes to repairing rotten window frames and sashes I first weigh up the options.

I know I can make good, long lasting repairs to any type of timber window but then I’ve been doing it for years.  I hope, after you’ve read through these pages, that you will have the confidence to give it a go.  After all you could save yourself a lot money and keep your old or period windows.  With moderate DIY skills you can repair and restore windows that others would just rip out. 

You can learn about the simple steps you need to take to repair window frames and sashes. See some examples of simple and extreme window repairs I’ve been doing during our cottage renovation. And learn a few other window repair related tips and tricks.
