So I sent a letter off last week by recorded delivery, formally requesting that Fairview sort out disputed items and apparently a reply from Fairview is in the post. By email they have already advised me that they will not rectify the major issues identified. As yet the NHBC have not responded to my letter which was sent by email so I will chase them . There has been a flurry of activity though , regarding some already agreed items. We have waited 15 months but finally 2 weeks ago Treachers Glaziers were asked to repair glazing that we were told was causing problem leaks through doors . When Treachers experts( that’s you Dave)  arrived and inspected, they found that in fact , the vent holes in the frames were letting in the rain. Some mastic and re-glazing later, all seems water tight. I wait with trepidation the next heavy  rainfall. However, what annoys me is that we have been told for the past 15 months that the glaziers were being slow in responding. All the faxed letters to them , point to the fact that they were only informed 2 weeks ago! Another less than ideal situation… The leak detection system is being replaced yet again….we do not need alarm clocks as this goes off every morning and wakes us up….yet it never went off when we had a genuine leak……
