Cost of installing new door opening

SargentDuck

Hey,

Can anyone suggest a guide price for installing a new door frame in a house? We are looking at putting french doors into our sitting room to try and get a little more light into the room and I was wondering does anyone know if its a costly/difficult job?

The house is build on 9" cavitys (ultra warm I know ) and the room is drylinded, there is nothing there currently (no existing window) so would be needing to knock out the opening.

We are replacing the windows in the rest of the house, so though while we are ordering everything else we might see if the budget could stretch to this too.

Thanks,
N.

Take advice from say a Structural Engineer, before you take on this project.
It's not just a case of knocking a hole in the wall, as the wall above the opening will have to be properly supported, and you will need a new concrete head, or maybe a steel rsj installed, over the new door.

Cheers for the advice, now I just have to find one willing to come out for such a small job

I had intended on getting a builder in to do it (I like a little DIY, but not this!!) and assumed a concrete head would be needed, never thought a steel RDJ would be needed.

It depends on the size of the opening, but as important is holding up the walls above, while the opening is made, last thing you want is a big crack running up the wall, where the blocks above have moved.
