Replacing Sash windows with pvc

thejuggler

I'm looking at a property at present which has old timber sash windows which will need to be replaced. I was wondering if it would be acceptable to replace these with white pvc windows which will be maintenance free?

The house is a semi detached in an old estate. As far as I can see the other houses still have their original sash windows

I'm also thinking of making other changes such as an attic conversion, putting in a stairs to the attic and velux roof windows to the rear of the property (not visible from the front). I'm wondering if I will need to apply for planning permission for these changes or is it not necessary?

Or if I was to simply replace the sash windows with new sash windows would this mean that planning permission would not be required?

you can get pvc sash windows which are double glazed that look exactly like the original wooden ones....don't know who from though

only close up will you be able to tell they are different

How old is your house? Victorian?

If your building is deemed to be of architectural merit by the planninhg authority, then PVC windows may be objected to. This is unlikely to happen in practice.

PVC windows have a fairly short lifetime. I have had houses with PVC and would avoid them in future. Problems include: Discoloration over time. Can't be painted. Frames crack eg when kids stand on sills, and can't be repaired. Handles and other fitments break off and can't be repaired. Difficult to do things like change the locks as the screws tend to work themselves out of the plastic over time. When a PVC window is knackered it goes to landfill.

There are aesthetic considerations but this is a matter of taste. In general you will reduce the market value of an old house by fitting plastic windows. The wide shiny frames and thick glazing bars are an instant giveaway and are a becoming like the stone cladding of the 80s. Worst are the replacement sash windows that swing open rather than slide. Many people who buy old houses start by chucking out the PVC rubbish installed by the last owner.

There are several firms that will refurbish or replace wooden sash windows, including double glazed sashes. Most likely, only refurbishment is required. Once done, you need to check the windows once a year and touch up as necessary. It's not a massive job, one morning in the summer would do it and your windows will last for decades this way.

Attic conversion and velux windows to the rear do not require planning permission in general, check with your local council planning web site. Velux windows to the front usually do require planning permission. Refurbishment or replacement with wooden sashes do not require PP. Again check first.

Thank you for the information. Looks like I will stick to the sash windows then - probably they just need minor refurbishment and a coat of paint.

I guess there is a reason why none of the other houses in the estate have changed theirs.
