I have the same issue but I'm not renovating. I can't even register a print now. Booked in with apple tomorrow!
Before anyone says it. No my hands aren't dry, I use barrier cream at work and hand cream after work.
Last year I had my fingerprints taken for the Global Entry Program and the agents told me that people over 80 or who've done a lot of hand work (including washing dishes) without gloves are pretty much unreadable - and I'm guessing their sensors are better than an iPhone's.
On the plus side, you can take up a life of crime and not get caught.
