[Closed] Cost of fitting fire doors ?

Do you need new frames fitting or are they to be hung on the old ones? Also consider that the doors are heavy and I’m guessing they are to be carried upstairs? I usually charge £40-£60 to hang an internal door but try to do all cutting/planing outside to minimise dust/ cleaning up. This could mean each door being taken up and down stairs numerous times which is difficult for one man. If i know I’ve got more than 3 fire/oak doors to hang upstairs i will employ a labourer for the day to help. This will obviously be reflected in my price.

1/2 hour requirement are 44mm so you'll probably have to move clapping strips on door linings. If they are rebated frames you will need to replace the frames to accept a 44mm door, both will need routing to take intumescent strips. However.... are they (building control i presume) after 20min compartmentation or 30 mins. It does vary and 20 mins can be obtained by standard doors without intumescent strips. All the above can obviously add additional cost so it' worth clarifying.

We did a loft conversion 10 yrs ago (Scotland regs) and had to change most of the doors to fire ones with chain closures. They were about £200 each.

Frames are staying, 3 doors upstairs 1 down stairs

sandboy, where are you based ? I’m north London ( so I’m probably being charged extra Vaseline London price)

So if the frames are staying what size door? 38 or 44? And what fire rating have you been told to achieve?

match existing where possible.
 Fix 30 minute fire resistant timber doors to habitable rooms and hollow doors to bathrooms within converted area.

I’m in Norfolk, so I’m cheap compared to your location. My brother recently paid £280 for one fire door for his loft conversion in Brighton.

Ill have to to find out

Do find out as it can make a big difference in availability and price.

Holy shit how big is that smiley on the text quote 🤣

So as a rule standard 30 mins are 44mm. Yes they are heavy ish but that doesn't make fitting any harder. Any closers required such as percos or similar?  You'l be looking at pair and a half of 4" butts for each door then your choice of furniture. 300 a door seems steep to me but if that includes a good choice of styles and furniture then liveable, we pay about 70 quid for a plain premdoor 44mm oak venneer door but you wouldn't want them in your home as they are bit to boring and industrial.. A decent joiner will swing 4 doors in a day in new frames. As they are in to existing frames then it is more time consuming.

A quick Google suggests something like this is available.

So 300 a door is steep.

Thought they had done away with the requirement for domestic fire doors in three story properties?  All you need are self closers.

I'm a North London /Hertfordshire based loft converter and as far as I'm aware the regs haven't changed.

I build to the following - either every habitable room has a smoke detector with heat detector in kitchen or you have linked smoked detectors on each floor (on the landing area) and minimum 30min protection fire doors on every room except bathrooms.

Standard doors are 35mm thick.

30min fire door is 44mm

60min door is 54mm

You can however get 35mm 30min fire doors, they are out more expensive but save on disturbance of door frames.

£300 a door fitted is a bit steep, but depends on the style  and price of door you've chosen.

Yep, you are correct, I don't do much housing.

do linked wireless detectors like nests meet regs?
