Putting a upvc door in a garage

[glenn2503]

I had a new front door fitted and am going to put the old front door in the side wall of my garage,

How much bigger than the door do i cut out?

Do i have to put it on the sill or can it go straight on the brick?

Does it go onto the damp course?

Do i need a lintel?

When fitting the frame do i take the door off the hinges and fit the frame seperately then put the door back on?

Any help is very much appreciated.

Door needs to be plumb, I'd allow the cut out to be 20mm larger than the door itself, give yourself 20mm on the height as well.
Sit the door on a new sill, most likely a 150mm one.
Sit the sill on the damp course, might have a step over though.
Lintel?? Dependant on roof structure and weight load above door, I would say yes.
Taking the door off does make it easier, make sure you have the clearance to get the door back on before fixing. Also make sure the door is plumb, you don't want any twists when the door goes back on

The problem I have is that if I put it on a sill I don't think the door will fit underneath the joists let alone put a lintel on.

What measurement have you got from dpc to the joist??
What is the door height??

 

[glenn2503]

Dpc to joist is 2120mm

Door height is 2064mm without sill the sill is 35mm

You have 20mm to spare, sounds ok to me

Yeah,i won't be able to fit a lintel in but its not a major problem imo,i may put a noggin in the 2 joists that won't be supported,1 in each side so they r supported by the joist that is on the wall,if that makes sense lol
