Dear Gilian I would suggest to post job description on main website if you do not feel confident to do it your self. Once you've posted a job with us and had a local tradesman quote, you should have been sent an emailed link to his profile. From here, you can read previous customer recommendations and ratings. I hope this will help Best regards Rafal

The pipework needs extra pipe clips to hold it in place, the system needs a thorough cleaning, or if this is already done correctly you may need to fit another expansion vessel. Jan South Coast Boilers

You are not obliged to go with any of the quotes- but ever job that's posted is paid for by the relevant tradesmen.if they contact you that means they are interested in your job. If one of them are awarded the job then great news for you both. ratedpeople.com Regards Michael

I would start by checking if any of the pipes seem wobbly or insecure and add extra clips if necessary or if the pipes have enough room to expand ( the pipes expand when they get hot ) or are restricted as they pass through flooring or walls, or are they touching other pipes whilst expanding.
