    Exterior door threshold - water leaks - suggestions?

    I recently installed one of these thresholds and door sweeps on my front door (photos below). The problem is that in a driving rain (aiming toward the front door), some water is still getting in at the seam where the little plastic weather stripping meets the wood on the threshold.

    Any suggestions?

    Add a storm door? That would be the easiest thing to do but it is expensive. My sister's first house had the same problem and after trying various combinations of door sweeps, weather stripping, etc, she added a storm door and that fixed it.

      How tight is the bond between the sweep and the wooden threshold? The reason I ask is that the threshold has ajustable screws to increase/decrease the hight. This might fix the problem

        Is the door sealed around the frame?

        you could try a door sweep with a rain drip cap to keep water from running down the door and going inward at the bottom.

        notice how this door sweep has a rounded front edge, the water will drip off of it.

          It's pretty tight, and the adjustable part is lowered all the way. The water isn't getting in between the sweep and the top of the threshold. It's getting in between the wooden part of the threshold (the part that has the adjustment screws) and the small bit of plastic weather stripping between the wooden part and the aluminum part.

            This might help -- I'll see if I can find something like this.

            I might try running a bit of caulk between the wood and aluminum on the threshold (under the weatherstripping) first and see if I have any better luck with that.

              It's not easy to fix.

              We had some improved results using a drip strip at the bottom of the door. Something like this: http://www.kilianhardware.com/acbrondriped.html

                I tried a couple replacement sweeps, an extra drip flap etc. and they helped but didn't totally fix the issue. With strong wind it's not very hard to blow the water uphill. I ended up solving the problem for real by adding a storm/screen door...
