We rent a lovely grade 2 listed, C17th house. And finally the landlord has hired some builders to do some much needed repairs. One of these repairs is to a wooden windowsill which has basically all but rotten away (did I mention the works are much needed?). The builders had initially, I assume, underestimated the repair to this as I overheard them earlier coming up with a new plan which included using cement and wood. Now having always been lucky enough to have lived in beautiful (if, drafty) old houses, I feel strongly that as it is listed and it’s a street facing window that a botched job and not replacing like for like (all with no input from anyone in a conservation role) is just wrong. My DH is of the opinion that we don’t own the house, we don’t want to make trouble for the guys carrying out the work as they seem really nice and we don’t want to rock the boat as far as our landlords are concerned. So we just ignore it. But it doesn’t sit well with me at all and I want to anonymously contact listed buildings. Is this the right thing to do, or is my husband right and we just stay out of it?
