I had some new windows fitted. There was a delay with window boards on my behalf and therefore the fitter stated he would return when I had them and complete the whole job. He left off the trims around the support poles etc internally/externally and other bits not completed. £1000 is outstanding which he stated would be taken once the job is complete. Ive emailed him many times asking when he will return but seem to being ignored. Do I need to put this in writing stating that I will hire someone else to complete the job and bill him for the works? But I still owe him the £1000 though. Any advice in my circumstances? I dont want to hire someone and down the line the fitter asks for his money.
