We went through les Forges yesterday & , rest assured, No 4 is still standing
I think you'll have some good neighbours there as they are always ready with a smile & a wave when driving through, but it certainly sounds like you have some work to do !!. I take it you aren't sleeping there in January ?. With regards to the Mairie TBH I've always found the secretary not very helpful on the odd occasion I've had to go there, also as google translate is not perfect it does not surprise me you've had no reply yet. Not sure if a " miniscule budget" fosse exists anymore as they all have to be up to French spec' now. As Martin said, Russell Waite has been going several years & has a good reputation , although not particularly local. It is always a good idea to get 2 or 3 quotes for whatever you are having done. In an effort not to "hi-jack" Martin's original posting I will send you a private message with local contacts & maybe help with some of your questions.
