I have a 1918 Craftsman bungalow my wife and I are starting to restore. My problem has to do with damage to the trim around the doorways and some of the baseboards. There are numerous chips and scratches on the corners of the trim. I was told by the realtor when we bought the house that one of the previous owners or their child was disabled and their wheelchair or similar assistive device made the chips and scratches. My question is how do I repair the damage? The woodwork is stained a reddish oak and the scratches and chips are all the way through to either the original wood or an original lighter stain. Can I use colored wood putty or filler to repair these mark or is there another solution short of stripping the woodwork and refinishing it? Any suggestions would be helpful.
