    Working on an old bungalow renovation - Kitchen is very very cold, have noticed that a pvc door that was previously installed is very draughty and cold... rest of house is warm but this particular corner of the kitchen is barely getting heat despite being 2 foot from a rad. Door install is clearly not the best - how can I rectify this. At the minute i'm not worried about the step finish etc, just to lock out the cold and air. Also, unsure if proper DPC has been fitted to this and another PVC double french door - could any action be taken without taking out the doors themselves... pictures attached.

    Can I use expanding foam and/or sealant to seal air from outside?

    Immediatly surround the pvc door, floor and frame temperatures are very low - floor barely reaching 8/9 degrees.

    Centre of kitchen floors reading 14*C - where as room next to kitchen 17*C on floor, room next again 18*C

    Yuk! Have a look at my site on DraughtBusters


    Foam is ok to fill voids, I would like to see silicone sealants used outside, except across the bottom. There should be some drain channels and it would have been better practice to fit a sill or stub sill onto which these could have drained then that could have been sealed to the sill and inside of the frame. So for me the bottom only gets sealed internally.

    Inside I would seal with acrylic sealant

    Looks like most of the problems are with the frame/wall junctions

    Lots of care and attention to detail needed, but it is all easy.

    What is your goal? What's the construction of the door and its U-value etc? Are you planning to replace it?

    What sort of DPC would you expect?

    Most PVC doors have a replaceable rubber seal most in fact have 2 one on the door and one on the frame these should get compressed when you move the door handle up.
    the seals may have deteriorated or not been fitted in the first place .

    What does the close against?

    There is a system in the hinges to adjust clearance between door and frame to eliminate any gap between the 2.

    Have a close look to see if there is a gap in any of the four faces where the door meets the frame

    Jack frost will find his way through any gap .

    good luck .
