We recently had our old galvanized pipes removed and re-routed from a
very old house, which has resulted in a 3.5 inch square thru a stair
near an interior wall. The grain of the wood stairs (painted, non
carpeted) will be hard to match, so this will most likely always look
like a repair, but anything is better than seeing down thru this hole
to the basement floor :-). Initial thoughts are to hammer a similar
sized wood block and support the back (underside of the stairwell, ie,
not noticeable) with thinner wood. Then paint over to match.
Any other ideas?
Also, the same removal project left a more sizeable rounder hole in the
side paneling next to the steps (inner wall I spoke of earlier). I'm
not sure I'll ever find this old wood paneling anywhere (would be nice
if there was an extra piece in the garage loft), and it's not painted,
but once again, anything is better than walking down to the basement
and gazing into the laundry room on the way down, lol.
