In the recent storms, I noticed that one of my patio doors is whistling. On closer inspection, I see the wind and some water is getting through the bottom of the door.
What is missing?
Is there some kind of weather strip I can use for this?
TIA

 

Depends on the door...is this a slider...a single swing..french door..etc? Different fixes for different things. They all have some sort of weatherstrip...some works better than others.

 

Hi Vic,

thanks for the quick reply.
It's a slider.

 

Ok...most sliders use a pile weatherstripping of some sort that is applied to a lip on the exterior of the door and seals against the track on the bottom.

Cheaper vinyl and aluminum doors have lower tracks and therefore less distance to prevent water intrusion and less area for weatherstripping.

Quality doors like Andersen have raised tracks and double weatherstripping.

 

If this is missing on my door, what would you recommend as a fix?

 

When the door is 1/8" from being closed, the reveal along the latch side should be perfectly straight. Check that first. If it's crooked, you have the rollers out of adjustment and need to turn one higher or turn one lower.

It's possible that someone raised the rollers up too high on the operating panel, and the bottom weatherstrip isn't fully contacting the monorail. Find the adjustment screws (usually need a #1 phillips screwdriver) and try to turn the screw until the door lowers a little bit. Might not take much. Adjust both rollers down the same amount. Some rollers adjust by inserting the screwdriver under the ends of the sliding door, right above the monorail. Others have 2 adjustment points on the interior side near the bottom, sometimes covered with plugs.

If the water is coming in at the middle of the door, it could be out of square and not interlocking properly (see above to correct crookedness) or there may be a missing/damaged seal at the bottom of the interlock.

When water comes in, it could also be dirt clogging the exterior track or plugging the drainage system/weep holes and backing up.

 

I don't see any bottom weatherstrip as you described but on closer inspection, I can see that the furry strip which is sealing the sliding door on the inside is missing. The door itself is level, the reveal is all equal etc but the whole length of the bottom of the door has an gap that allows the wind and water to get through. Can I get a replacement furry strip from a homecenter?

 

Forget the home centers. You'll have to take a sample piece to a local glass shop and they will have or can order it for you.
