Fill gap between dry wall and window apron

9 years ago

I need to fill a gap between the drywall and a window apron, The gap is 1/4 to as much as 1/2 inch wide. I was thinking of putting in a backer using thin, narrow pieces of wood and then filling in with drywall mud.

Is there an easier way to do this? You face this window as you walk into the room.

Remove the apron and duplex cover. Install drywall, tape, mud, sand, prime, paint, and reinstall the cover and apron.

Yes, that would work. I'm hoping to find a less disruptive repair process.

backer rods & caulk.
the wood & drywall mud have little flexibility.

We have been using spray foam insulation as backer for large plaster voids. The green-label stuff that is "green" seems to be the best, as it cures out super fast. Then trim flush with a thin saw blade, vacuum the dust and tape with durabond.

Remove the apron. Fabricate and install a 3/4" x1" x length of apron below the stool. Reinstall the apron.

The house is over 100 years old. The drywall was installed sometime between 1960 and 1990, I would guess. Along the way, some framing dry-rotted and the sub-sill dropped. The apron was barely attached when I started my project of window sash and frame rehabbing and adding pulleys, chains, and weights. So I reinforced the rotted framing wood and raised the sill back up. I didn't realize there was going to be that much of a gap when I put it all back together.

how about ...

stuff hole with insulation ...

add a piece of molding over such ..

move on with life ... no need even for compound..

or.. remove the apron.. insert one inch piece up under sill ... replace apron one inch lower ...

i am thinking 15 mins.. if you have the ability to rip a one inch moulding .. and no wet cleanup ....

so its 100yrs old.

are you trying to make historically accurate?
if you are..hire someone..your way out of your league..

trying to fix the problem..
ok.

drywall..the newer solution
plaster/and lathe..the old way..much harder

easiest..hire some one..this is an easy fix for some anyone
that fixes sheetrock..
