Drafts under front door

[applesandpears33]

We had our front door replaced a couple of years ago and it has been really drafty ever since. There is a UPVC frame that the door sits in and there is a gap between the bottom of the frame and the carpet. The drafts come in through that gap. I have tried to stuff the draft excluder that you can buy for windows into the gap but it isn't really cutting it. I suspect the door frame was not properly installed and sealed at the bottom. Is there anything I can use to seal it on the outside?

Brush strip on the inside.

Post some photos please, gap, bottom of door and sill, inside and out.

Sorry, it is sunny outside at the moment and the photos aren't great. I'll post another one from the outside when the sun goes in which shows the area directly underneath the door.

Carpet is not supposed to form part of the weather seal for a door. I’d try 2 routes to get sorted

1 - Contact installers if still under guarantee and invite them to sort it as it’s simply not right.

2 - If outside guarantee then if seal the gaps where the draft comes through (both inside and out). Use mastic or possibly builders foam depending on the size of the gap. Really you will need to have a good look at the and see how much of a gap there is and decide on the product, but I would expect it to be mastic.
You can buy mastic for both the inside and outside or both and it should give you an air proof seal.

Good luck.

Seconding what Grumpy has already said, especially about going back to the company who fitted it.

Oh I see what you mean. Brush strip is not correct for that gap (you use it for a gap between the door and the sill)

Some kind of waterproof, non-hardening mastic or similar material would be used. probably silicone sealant (not acrylic caulk, which cracks) on the outside of the gap, maybe waterproof neoprene strip foam for the gap under the rest.

I agree with getting the installing company back, they have not completed the job.

Unless they are completely inexperienced and incompetent, they must be filling this kind of gap every day of the week.
