Advice on which trade is best to install bifold doors?

Posted by Susan Wall, on Wed 27 Nov 2013 01:57pm

I have ordered some bi-fold doors (aluminium exterior/oak interior) which are top-hung, due to arrive next week. The builder working on our kitchen extension says he won't fit them as doesn't want to be responsible for any issues with them. They have full, clear and comprehensive instructions. The supplier has a fitting service, but they cannot come until late Jan and we need the work done in next 2 weeks. So is this a job for a carpenter, a builder, or another trade? Thank you

Hi Susan, I'm Robert from Saddleworth Window Outlet. As you have already found, even established quality builders sometimes turn up their nose when asked to fit Bifold doors. Of all door types, bifold doors need the most exacting care and expertise to fit properly. Due to their unique width spans and opening configurations, the doors have to be fitted to precise tolerances for them to operate correctly. We use digital laser levels when we fit these doors. If you have any concerns, I would contact your nearest reputable certified window and door fitter, to see if they have experience in fitting bifold doors. This is not a task for the uninitiated. Hope this helps. Rob Saddleworth Window Outlet

I have fitted bi fold doors and they can be problematic and the opening hss to be almost exact.i empathise with your builder and now insist the client has the manufacturer to fit them.beware of this as well unless they survey the site beforehand as they may refuse to fit them if the lintel etc is not to their liking. Hope this helps

Hi Susan, it would be best directed at double glazing industry. Bi folds can be problematic so make sure there is an installation on the warrantie. I would anticipate the cost to be around £500 depending on number of doors etc. If you are in Lancashire I would be happy to look at them for you. Hope the above was of use to you.

these are a complicated item to fit so you equire a Upvc instaler who has experience with Aluminium Bi Fold or an Aluminium Installer (a little harder to find) to fit them, I would not let a builder fit them as there are issues with weather sealing and toe and heeling
