I'm doing a job right now that has sustained some water damaged plaster. The plaster installation was directly over an exterior brick wall and wet for years. Appx. 100sq. ft. was previously removed and has to be patched back in to the adjacent wall plaster.I've done plenty of drywall finishing.concrete finishing and some stuccoing. It seems as though our plaster guy is planning to go to go to the Bahamas with the money he wants to make on the job.I don't begrudge him a fair profit but he's raised his price 250% since giving a price that we bid the job with.My question is this. Anyone have any thoughts about doing this job in house or would it be wise to patch it back in with drywall? Any suggestions would be appreciated.
