Worse company EVER!!!!

 Absolutely shocking workmanship.

Gaps you could drive a bus through. Draughts like a gale. I have all the videos and pictures to prove it easATgunbase . I went through warranty process and 4 visits later a slight improvement. Tried to use warranty again and they say they went out business as everest windows. So my lifetime warranty is useless. A couple of months later they open up as everest 2020. Look at companies house and you will see they have been doing this for years. Screwing over the customer when times get tough.

Today I fixed the balcony door took off the trims and I could see daylight over the frame. They chop up your bricks to make it fit then fill with foam then put trims over. Stopping no sound from the environment or heat escaping. Why because that takes 5mins where as they should plaster back. Absolutely shocking will never use Everest again EVER and hope to spread the gospel of Everest quality (NOT) far and wide.

Shockingly bad installation. 11windows 1 door. I installer 1 sweeper up. 3 days. Recipe for a terrible installation and it was! Your the best as ripping people off.

PEOPLE WAKE UP Everest are terrible theres way better out there.

Standard answer below (note the warranty process they are palming you off to will cost you £100 per claim and is ardus and the company will deny your claim)
