Bifold doors fitted incorrectly, fell out onto my husband- very dangerous. Windows fitted incorrectly. Incorrect side panels fitted. Poor customer service when attempting to get these issues rectified. Denied having correct side panels despite paperwork from own surveyor. No follow - up call to rectify minor problems such as missing screw covers. When we finally got a service call, fitter arrived without correct equipment. Assured us someone would call. No call came. Still waiting for all these problems to be rectified six months later. Poor service throughout, I would never use them again.
