My in-laws bought a front door from Everest 2020 in March 2021. To this day over 9 months they have not had a satisfactory replacement letterbox. The letterbox which came with the door is not fit for purpose. It prevents the door from opening fully which should have been picked up on when measuring took place. This company have come 3 times with the same style letterbox for replacement - useless if the first one is not right. That’s on top of the times they went to fix a leak and draughts. They were supposed to go yesterday- they say they went twice and no one was in. My in-laws stayed in all day for the letterbox to be changed. The appointment was for between 8am and 10am. They claim to have gone at 12.30pm and 1.30pm. My in-laws were in all day, why would they go out when they expected a person to come to replace the letterbox after all this time. The door had a leak and draughts when first fitted these were fixed but took along time for the company to fix. My in-laws asked me to take over their situation with Everest because they found it all too stressful. Both are in their eighties and with ill health. Go to another company for your doors . A company that treats their customers with care and respect and who does a job properly for a reasonable cost.
