I am at my wits end. Really don't want to fall out with our neighbours but it is now getting ridiculous. We live in the top floor flat and they are in the bottom flat of a semi-detached house - together we share the freehold of the property. We have already been more than patient as the work started in 2021 but it is still not finished. The owner has tried to do some of the work himself as a builder. When i asked for an update on when it should be done there isn't one as they can't find anyone to do some work that is needed (same excuse has been given since Christmas!) When we last redid our mortgage we had to pay a little more because of the risk of the extension (it was ongoing and there was a hole in the back of the house - there still is) We did not tell our neighbour this and just swallowed the extra cost, but the mortgage renewal is coming around again and we thought it wouldn't be a problem as it would be more than finished by now. I have now told our neighbour that we face having problems remortgaging and may have to pay more due to the hole in the back of the house but they don't seem to realise fully the implications - and the impact the work has had on us on a whole. Noise, mess for years. We've not been able to enjoy our garden or really invite friends around as the work has been sporadic and we've not always been updated as to when work is being done. We've tried to stay friendly, polite and patient but now we're coming to the end of our tether as we really can't afford to pay more again for our mortgage due to their overrunning work! Does anyone have any advice?
