I had a large patio door glass unit that had ‘blown/missed up replaced by Double glazing doctor, in March. It was £330 but it was a large unit. I believe the fitter said he lived in Worthing.
Used these several times (must be close to all of our window panels having been replaced over the years) and in fact they’re in next week to replace a few (they also do lock/handle repair/replacement etc)
Great service, quick quotes and around a month from quote to fitting.
