My house needs a repaint and some fascias replacing due to rot. I'm thinking of going for UPVC fascias/soffits/bargeboards instead.

A few questions:

1 - Anything to look out for with UPVC?
2 - How do they attach the guttering to the new UPVC fascias? If the guttering is old will the seals fail if disturbed so also need replacing?
3 - If *whatever the UPVC stuff is attached to* is rotten then will the UPVC contractor point that out or just attach the UPVC stuff to rotten wood work and disappear into the sunset?
4 - I assume ventilated soffits are a must?
5 - Does UPVC deteriorate in the sun quickly or will it be good for decades?

Basically any advice would be good thanks.

they should remove old soffitts/facia//barge boards e.t.c but depends on how good you contractor is

guttering will have to come off to fit new facias anyway


my white soffits and facias have been up on mine for 15 years and no fading/yellowing but as with everything i suspect it depends on the quality of whats fitted.

on the off chance you do guttering as well I would suggest don't get brown (it looks crap when it fades) and don't get white as it always looks dirty

yes vented would be a good idea with modern insulation levels

As above, if you're current stuff is rotten then you want that removing and new UPVC replacement boards fitted ie you don't want them to just fit a thin capping over the current boards. Make sure any quote you get specifies what they are quoting for!
Boards should be a minimum of 18mm thick (in my opinion although some may say 16mm) so guttering brackets will just screw into that.
Might be worth getting eaves trays fitted at the same time depending on what the felt is like.

Usually it is easier, cheaper and better to over clad the existing wood, it gives a good surface to nail and screw into. Get the guttering replaced at the same time.

This is good advice. A 10mm over fascia vent will also negate the need for soffit vents.

I’ve just had my filthy, 20+ year old, white UPVC soffits and gutters cleaned by the window cleaner and they’ve come up brilliantly, they look really good now and I doubt they’ll need replaced for a good few years. £70 well spent and he cleaned the downpipes, window frames & doors in the same job. UPVC definitely seems to last well and keeps its look with basic occasional cleaning.

You are right though, things like old cobwebs seem to show against the white which might not happen with other colours.

Thanks all. The wood is largely good but the box ends are rotten.

I hadn't realised they overlaid thin UPVC over the existing wood as one solution. I thought they stripped all existing wood off and replaced with UPVC.

It only gives a good fixing for the UPVC cladding if it's sound, which isn't likely otherwise it wouldn't need replacing & it will also carry on rotting under the UPVC. Cladding the old wood is a bodge.

Yes the old wood in places has some rot so does need replacing. I've advertised for a contractor so I'll see what they suggest.

Many thanks for your thoughts.

I had the lot replaced. I specified with all the companies that quoted that I wanted any rotten rafter (?) ends replaced - they all said they did that as otherwise they'd end up having to replace them on guarantee. The company I used in the end scarf jointed some ends in on the few rotten ones.
