Water under door thresholds.

This diagram is intended to clarify what I discussed in my previous post.

Attach a thin wood strip drip edge somewhat thicker than your sill to the front edge of the sill. Smear adhesive all over the drip edge and screw or nail in place. The adhesive will not only stick but also seal it from water.

I’ve got some extra lattice wood in random, but short lengths. I could use that. However, due to the much wider door threshold, I think aluminum sheet cut to length and depth then screwed and glued would look nicer. It’s quite ugly at the moment and aluminum might dress it up somewhat.

I see a simple fix thanks to the photo.

Copy and paste in the Google search box:

exterior door drip edge sweeps

Check photos in images

I'd think you could buy those online (at the appropriate door width) and have them shipped to your locale? I have successfully retrofitted a few of the extruded aluminum variety with the large curved lip and the integral sweep.

Additionally in your specific application I would bevel the tack strip AND bottom plate that is directly under the center of the door sufficiently such that the drip edge will shed water onto the bevel. That will help keep water from pooling under the door. Also, if you haven't already done it, caulk the seam under the side lites. Good luck.

If it fits not really for the current situation, but maybe for other readers:

It the offered products are not appropriate with the needed door width, I can imagine, that it isn´t a big problem to cut an bigger length....

I may not have explained myself well. Photos with notes might help. In my case, water is NOT come in under the door threshold. The door is outward opening and has a substantial overhange and seal.



It's coming in at other points.




Clear evidence of leak around door frame.



I don't have a photo of it, but before we had our flooring installed, the concrete foundation showed leaks under the bottom ring near the door (and windows) after heavy rain. I may have (mostly) fixed it with expanding PU but I'd like to add extra protection and dress up the entry.

This is how it looks now.



I'd like to add drip edges at the top and bottom. Also, do a better job of caulking with clear or brown silicone sealant where there are gaps in the wood trim.

I've marked up where I think I'd add aluminum drip edges, probably formed from stock aluminum sheet. I'll do something similar with the windows but only at the bottom sill where the frame meets the foundation.



Sorry, for the confusion. I know the original thread was about water under door thresholds but it can come in at various locations. Windows and doors are frequent leak points, right?

OK. Caulk is your friend in this application. I'd caulk every/all exterior and interior seams at the door. The lites, the door, the plates....all seams.

The drip edge sweep I mentioned is designed to shed water onto a slope away from the dwelling. That's why I suggested beveling the ext trim and the bottom plate below the door. Water will not pool it will move away from the yurt. You could likely fashion a BIG drip edge yourself with flashing if you did not want to do the beveling.

Additionally you might consider building a small awning at the entry, that tucks under the yurt cover above the door, and extends up the rafters a ways, and attaches to them to secure the awning in inclement weather. Driving rain blasting at the door is definitely hard to turn long term with simple sweeps and caulking weatherization.

Just tossing out some other ideas that aren't too much money. Fortunately I guess (?) you don't get extended rainstorms. We don't get them here. But, we have a huge porch so even if we did the ingress of water would not happen. It certainly WOULD occur because our entry door has none of the measures I have suggested.

I was thinking the same thing, especially a silicone based one. I am no master-builder so I kept my mouth shut lol..

I would just seal it up.

All great comments, chaps. It gives me a lot to think about.

Caulking - easy.
Aluminum drip edges - easy.

I like the awning idea but it's a step up in complexity, especially on a curved door and curved framing (headers and sills). I like flexibility and would love a retractable / removable capability for an awning - even more complex?.

However, the awnings may not be necessary. Our hallway / bathroom between the 2 yurts design is intended for wet or cold entry and exit with a substantial overhanging roof in the front where the door is. So in bad weather we could just avoid opening the yurt doors entirely avoiding rain and cold ingress. We're aiming to have the hallway/bathroom done in the next 2 months.

Our summers can be very rainy but only for 3 months, peaking in July. Most of the year it's very dry or snowy. However, our mountain location makes all weather conditions more severe.


Note the roof can have a substantial overhang and the entry door faces south. Prevailing winds are from the north so there's less chance of driving rain towards the door.
