What is the finish going to be? We have come in on jobs that had to plug natural wood doors/beams- sanded smooth and applied the finish. Sometimes the patch shows.
I whip out my palette and blend in with a quick grain/color match. WHen done, no one knows it's there.
I suggest hiring a local faux painter with good portfolio- cheaper than replacement. We do it in an hour or less.
One job recently, a contractor installed 150 year old beams on ceiling of a remodeled kitchen. They drilled 1" holes to use lag screws to hold them in place. Filling holes with plugs didn't even come close, so they called me.
4 hours or so later, it became a game by others to try and "find" the holes. Most couldn't be located...
A good faux artisan could help you out..
