Water seal for door.

[Dave Plowman (News)]

I have a south facing roof terrace and a combination of south winds and rain sees water forced in under the inwards opening door. The door is a custom made wood one in a wood frame. There is already a drip bar on the bottom of the door and an aluminium strip with matching rebate in the door

- about an inch high - running across the threshold in an attempt to stop this. But any wind just whips the water over this. What obviously is needed is some form of positive seal. The door is a very good fit already so there isn't room for a stick on rubber one.

My thinking is a rebated in magnetic one. Is this the way to go and any sources and info - or any alternatives? I'm running out of gaffer tape...

Not even draft excluder for window frames? That squidges down very thin,

I tried that and it didn't work. Being wood and not new I doubt everything lines up perfectly anymore so a simple foam one may not be enough.

That I am surprised at, should be enough for gaps 4mm down to almost naff all. Is this water really coming underneath or in through the jambs and running down the edge of the door/jamb?

To close the jambs off you can get strips of ali channel with a soft flexable blade attached. The ali channel nails to the frame and the blade presses flat against the door. Works up here... Bit of fiddle trimming correctly for the corners but worth it.

Would the silcone sealant and (greased?) cling film trick work along the top of the ali threshold strip to from a "custom moulded" soft seal?

Unhelpful suggestion #1: inflatable gas-tight seal in door frame.

Dave,

Is the "aluminium strip" something like that of a Stromguard waterbar (threshold)? If it is, try putting a 6mm x 6mm plough grove under the bottom rail of the door and over 'drip tray' of the aluminium strip - this stops the water being blown across the bottom rail and allows it to fall and drain out through the strips (stormguards) weepholes.

If the 'strip' is simply a flat bar, then try the groove trick in front of that - *if* there's enough room - or simly replace the strip for a Stormguard waterbar and that, along with the plough groove, usually works in the worst of weathers.

No - just a plain ally strip. Added by the builders.

I've just Googled Stormguard and it looks like I should try one of their products.

They seem to have a bewildering range. Any preference? The door has been rebated for this ally strip but would be easy enough to alter.

If height isn't a problem, just use the standard one

if you want the 'belt and braces' job use the Brydale the rubber seals will stop the draughts as well as the water.

After fitting many of these in my time, I would suggest that if you live in a high wind pressure area, that you also fit an aluminium weatherboard just above the Stormguard to stop the rain being 'pushed' down and under the door - especially if you use the standard sill.

If height is a problem (disabled access etc) then just use one of the lower profile bars with a weatherboard.
