New wooden door swelling...

[roxburd]

The old garage door was rotten and so in April I fitted a new one. Actually, this one:

Fitted it and then put two coats of paint on it.

All done, all good.

Then winter came and, basically, it has swelled up so badly that it no longer even opens. It is the cross-bar at waist height that has swollen - you can see by eye as the vertical bar is bowed out where the cross-bar has pushed it out. And the vertical on the handle side has also swelled a bit - enough to make contact with the door step/sill when it's closed.

I was careful to paint the top edge and even under the bottom edge. But clearly, the damp has got in. Given that it's the waist-height cross-bat that's swollen, I guess the rain hit the window and run down between the glass and the moulding.

I have covered the entire door with a tarpaulin to stop it getting any more rain falling directly on it. Now can't use the pigging door at all.

My question are:
1) Did I miss something? How are you supposed to seal the gap between the glass and the moulding? Over-paint? Sealant?
I remember the days of sealing the (single) glazing in with putty - seemed to work much better.
2) If I leave it covered, will it dry out and return to its previous size? I don't want to plane it down and then get a huge gap when it dries out!

Grrr. I was so pleased with it and then it goes and does this. Grrr.

Did you not read any of the reviews? 73% of the reviews say it's terrible, it's a wonder anyone would ever buy it give the reviews. Or that B&Q even publish the reviews.

All wood swells outdoor, no matter how well it's treated.
That's why it's good practice to leave 5/6mm gap around the door and a bit more at the bottom.
A good trick is to fit the door in winter after having left it to acclimatise for a couple of weeks (or longer.
Then a smaller gap can be left and it will open up in summer.
For reference, I built a garden gate last summer, left 8mm all around and 20mm at bottom.
It's now down to just about 3mm gap.

If it’s in an exposed position softwood will swell and rot quickly , exterior door needs many coats of paint. A door canopy would help but only if it prevent rain hitting door .
Did you fit drip bars?

All timber naturally swells up in winter's humid weather. Just trim it down, and repaint.

except Accoya.... Having made several external doors and windows for our house, I can confirm you can make them with tiny clearances and they don't change winter and summer.
