I hope you're comfortable doing all this. If it's the first time you're using any type of power equipment, it's my opinion your hubby wants the insurance $$$. This job is real easy if you know how to use the tools and are comfortable climbing around and all that.
Geesh, since he's leaving the job up to you to finish, either spend his $$$ to hire someone or find a friend who has some experience. My best to ya and hope this helps.
PS: I'm repainting the downstairs and upstairs these days. My wife asked me to do this since we're getting new furniture but you don't find me sending her out for the supplies. And I, possibly like your hubby, really ain't excited about 'the job'. It will bother me for a few days but once I get going, it's aaaaaalll over and done with. Have him read my Follow-up. FINISH THE JOB !!! (Now I feel better ...)
