Door Frame Width Help

[markmcd]

Hi,

I'm currently in the process of installing some interior doors and corresponding frames in my house. The problem I am having is the width of the walls... The existing casings were 97mm wide to cover the studwork and plaster on either side, but the timber I have is 95mm, being the closest that was available. This obviously means that there will be a 2mm gap between the frame and the architrave running round the door, or 1mm if I spread the gap over both sides.

Can anyone suggest a solution to this? I have searched and it seems that 97mm width timber is not a common size. The house was built in the late 1970's.

Many thanks.

well you can either router out the back of the architraves,or plant on some thin timber onto the door linings,or offer up the archs mark the plaster and carefully chop the plaster off.

If you have loose stops you can rip the linings where the stop will cover the gap, and plant the stop to suit.

There are extension linings available - these can be adjusted to suit the width.

Cut down larger timber, though b&q stock this.

If it's all to be painted why not just run down the gap with a bit of decorators caulk?

I thought this, but was worried it would crack and look a bit rubbish...?

Decorators caulk will possibly crack, and definitely pull away due to vibration. All caulks and sealants will look shoddy.

I doubt it would be anymore susceptible to cracking as gloss paint! Decorators caulk is flexible as well

I would fit the casing and then offer up some architrave to see how it fits. It its only 2mm you may well find it looks fine especially if its wide architrave.

For 1mm I probably wouldn't bother the angle the arch will sit at will probably be inperceptable, if you are worried I would do as greggers says and cut the plaster back

Apologies to above, i hadn't realised we were talking about a 1mm or 2mm discrepancy.

Thanks for all the help. Can you paint treated timber the same as regular untreated stuff?
