How do I deal with a flaky neighbour?

[user1471867483]

I’ve been facing some frustrations with my neighbour's recent building works, particularly concerning external wall insulation they installed. Unfortunately, these renovations have resulted in unsightly holes in the render of my property. I've also discovered a leak from their pipe - I don't know if this is causing damp patches on my kitchen wall which is particularly alarming as the damp spots are situated close to the wiring from my boiler, raising concerns about potential electrical hazards.
In an attempt to address these issues, I filled in some of the cracks on my side of the wall, while my neighbour offered to repair the holes created by his renovations. However, despite his assurances that he would "fix up anything left that needs fixing," his follow-through has been disappointing. He has cancelled on us twice now. Initially, we had set a date and time for him to come over, but he called to say his son was unwell and needed to be taken to his aunt’s. The second time, he claimed that his wife was stuck in traffic and would be unable to make it. Each time, I found myself having to rearrange my own plans, which has added to my frustration.
I’m thinking of calling it a day with him and finding my own builder. What do you think?
TIA.

Bob, I'm getting the feeling that you're not understanding the impact your building works have had on my property.

Here is a list of all the issues that need rectifying.

This should have all been covered by a Party Wall Agreement, but we were caught on the hop when the works started 12 hours after you notified us. And you've now cancelled meetings 3 times.

I want to keep a good neighbourly relationship with you, but don't feel you are giving the same respect in return.
Please rectify the issues by 25 November or I'll have no choice but to seek professional advice.
Let's not fall out over this, but please bear in mind the damage and inconvenience I've been subjected to.

Thank you. Just to let you know he pitched up 40 minutes late as (his words), "I had to get the baby (two year old) off to sleep" 🙄. I said that it was supposed to be 3pm and that I had to put down all the dust sheets again as I thought you were not coming", but he didn't reply.

Just an update:

Thank you all for your replies. After two cancellations and with the third and final visit turning up late by 40 mins, he pitched up. However, he still didn't get everything fixed. He was supposed to attend yesterday but he didn't show up (again). I texted him telling him to I can't keep waiting in like I do and he will have to fix the problem from his side now. He has cancelled four times now and I have to keep rearranging my day. My front doorstep is also damaged. In the same text I asked him when he's likely to repair that, but no reply. I give up. I'll paint it myself.

This is brilliant.
