Front door insulation

There is a lot of draught coming from my front door. I have put a curtain up but the main problem is the seals on the frame of the door and the door itself. It has lost its spring and in places is basically rotten.

Does anyone have any idea where to buy some more to replace it? I have attached photos in case someone knows of the particular seal I am looking for

Is that a wooden door frame? Looks like it could be a push-in rubber seal but what are the measurements and what does the cross-section look like, it's impossible to know from those side-on pics. Is it a bubble seal that has split?
Maybe a Stormguard TPE seal like this one: Amazon product.
It also looks a bit like this Munster Joinery timber door push-in draught seal but I haven't a clue where you'd buy it in England.


It is a wooden door frame, it does push in behind like a ?seam built into the door. I am at work today so I can't measure it or take photos but I will.

It looks a lot like the 2nd link. Tomorrow morning I will take a piece out and cut it and take a picture cross section and measure it.

Thanks for your interest

This is a picture of the cross section and it measures 12mm

Unfortunately it looks like the Munster Joinery timber seal only available in Ireland. I searched high and low for it online in England without success.

I suggest you try calling/emailing some seal retailers and ask them what they suggest as a replacement, or call/email Munster Joinery Wellesbourne and ask them if they can get replacement seals for you, after all it is the same company. If you call them ring the Reception number rather than the 0845 number.

Alternatively take a chance and buy the Amazon Stormguard push-in joinery seal for £7.29 if you can afford it. Here's a YouTube vid from Paddy's Diy on how to replace the seal:

.

Make sure you thoroughly clean the grooves in the door frame before fitting the new seal, an old toothbrush could come in handy here. A tiny bit of washing-up liquid may help if the seal is hard to push in, but once you get the knack it should be simple.

Update the thread in case this affects anyone else. Good luck!

This is great advice, I also couldn't find any similar seals on websites I was going to email a couple of the bigger specialist sites. I will try those things and when I have been able to sort it out I'll update the thread

Thanks

Sorry for hijacking slightly but hoped to leverage @Carbon 60 's knowledge or anyone elses...

Our front door is missing most of its seal, have tried to find replacement based on the profile of whats left but found nothing with the same profile, anything that has been close-ish has been much softer/thinner and seems to anticipate going into a thin grove whereas ours was glued into a flat sided channel.

I'm not 100% this is the original either given the smaller bit doesnt fill the channel properly but there is no branding on the door (its a metal finish inside and out) and the freeholder has no records of the manufacturer. Not sure what will be done if one door ever fails as they're fairly distinctive.

Hi @BobBob21

The seal in your pic looks like this Stormguard Universal PVCu push-in seal but you say it's a flat-sided channel. Is the channel plastic or bare aluminium? Can you clean some of the channel and then post a close-up pic?

What about the door threshold seal as well, is that OK or also perished. If it's perished too is it the same type of channel as the frame or different. If it's different post a pic of that as well.

Thanks @Carbon 60

All visible aspects of the door are metal, excluding the small round window, and that includes the channel for the seal. Whoever designed the building seems to have liked it as half the lower floors are clad in a similar bare metal at the front and all of the back of the building the same... no idea if its aluminium, zinc or something else

I'm not at home but I assume you were asking about the excluder at the floor? Would it be on the door or the step?

Usually there's one on or built into the step.

There seems to be a lip in the channel in which case one of these is will probably work,

Yes, the step. There should be a soft seal fitted on the inner face of the step where it meets the bottom of the door, the idea being to make it airtight and stop the bulk of draughts and rainwater from getting inside.

Thanks for the pic of the aluminium threshold plate. What's missing is the compression seal in the middle (as illustrated by Trajet's pics). No wonder you have draughts, it must get bloody freezing around and under the door in this cold weather. You need to get it sorted pronto and the door frame seals too.

I think the fastest solution would be for you to get an experienced professional in, let him get a good look at the door and its location, and tell you what your options are. The seals themselves are cheap and easy to fit for the most part but the condition and composition of the door, frame and threshold may need work too. Best to let someone who knows what they're doing assess the job.

I'm assuming (perhaps wrongly) that this is a double glazed door. If you know someone whose opinion you trust who can recommend someone, fine, if not I recommend you get some written quotes (not estimates), at least 3 if you can.

My go to if I don't know anyone or can't do it myself is Which? Trusted Traders, and fortunately for you there are a couple of dozen highly recommended dg door repair companies in your profile location London.

Here's the link, narrow it down using the filters if you like, although I guess they will all cover
any location, and look for companies that have the grey 'Doors' box, like the 1st company on Page 1, Pearson Glazing Ltd.

Take your time reading through the traders' customer reviews and make a shortlist. Then give them a call and see what each one says after visiting.

The foot detail of the seals is the most important part (section that clips in the frame) this is measured from both the widest parts of that detail, these are all profile specific, so some will fall out, some will be to large, you'd have to measure is and order a seal from that. Bubble gasket is the best for compression of the correct gasket is not found.
Extrudaseal have hundreds of types.
I'd probably recommend for the OP, to but a large bubble gasket with a stick on back, and try that.

Be careful with the low threshold, that looks like a Part M wheelchair access, so no gasket will fit on the base and you'll cover the drainage holes. You genuinely have a large flipper/bubble on the underside of the sash.
