Abnormal size door frames

[iMCaan]

Hi 

 

I had 15 FD30 door frames fitted. A couple of months later I've learnt that none of the standard size doors fit the frames. The closest standard size door is a couple of inches off in height and width. Unfortunately, all plastering and decorating has been done so the frames can't be altered for standard size doors due to cost of plastering and decorating.

 

Obviously, the joiner has stopped answering my calls.

 

The cost of bespoke FD30 doors is way too high especially to gain couple of inches.
Adding door lipping to the FD30 doors is also expensive considering they would need painting to hide the lipping. Is it permissible to fit the door lipping to timber fire rated doors? Do they still retain their fire rating?

 

What other options do I have?

 

Thanks

What actual sizes are your door frames?

 

WHO specified them the size they are?

They may just be metric rather than imperial. 

Metrics are 626,726,826,926 wide

2040 high

 

Lipping can be fitted to hardwood doors but you start to get into a bit of a deep dive into certification and you'd probably need a contractor who can certify the install unless BC are happy.

Apologies for my late reply.

 

I don't recall specifying the door or frame sizes. All I recall was telling him I needed fire-doors FD30 as it stated on the plans. He purchased the frames and fitted them. 

I started looking at doors online and asked the joiner for the sizes. He said I'll need custom doors as they are not standard sizes:

34x82" (2083x864mm)

33x82" (2057x838mm)

When I got a quote for the custom doors, it was way too high, more than double.

 

I contacted XL Joinery about door lipping and they say: 

Unfortunately both the fire certification and product warranty would be void by doing as you suggest. 

You'd need to make the opening smaller.

 

Is there a way to make the door frame smaller without removing the existing frame? 

 

Thanks

Fit another door frame inside the one that is there?  Will the architrave cover both if you do that?

Do NOT use the same joiner again.  I would be asking why HE made a unilateral decision to fit non standard frames thus forcing you to buy non standard doors. and suggesting the easiest way to remedy HIS mistake is for him to come and convert them to standard size at his expense.

 

2040 is the tallest "normal size"  That is what we have from XL Joinery, very good doors.

 

It sounds to me like he did not think, he fitted door frames to fit the structural opening which is usually over sized, rather than fitting standard sized door frames with appropriate packing to fit the opening.

Thanks ProDave

 

Definitely not going to go with the same joiner. I asked him to put the frames right and since then he has stopped answering my calls. I've given up on him. A different joiner is coming out to take a look.

sure its not the FFL level that is out/not accounted for ? Very very strange for even the roughest chippy to set 2 doors to 2 completely different heights.
