This company have disgraceful after sales service. I have been trying repeatedly to contact their service department to repair some windows (under warranty). Never a response. They have no service phone number, a service email address that bounces back (dodgy) and only an online form to fill in.....which never get's a reply. Your only other option is to risk phoning their sales/enquiries team who will then keep ringing you to sell you something. I never did receive a FENSA certificate from them either. My installation may have been 9 years ago, but their warranty is for 10 years! I was eventually fobbed off and told they would not fix any of my windows (without even looking at the faults) and just sent me their T & Cs. Their T & Cs state the following: “..we will replace or repair any defective part at no cost.” - this clearly indicates if there is a part that is defective (ie - not working properly) then you will repair or replace this. “Locks, hinges, letterboxes etc are covered by this guarantee” - Without inspection how would you know if one of my hinges are not defective? Your T & Cs are also vague with the stated term of 'etc'. This will be interpreted as any other mechanical component as you have not stated otherwise in your terms. Your T & Cs also state: “the company will not accept liability for general wear and tear or misuse, defects would normally be deemed to appear within one year of installation.” - in which case you are implying that any defect I am experiencing must 1) be expected of your products to appear within one year; or 2) assumed to be misuse. In which case, you would fully accept a window of yours not to shut properly within the first year of installation. An absolute cowboy company with a worthless 10 year warranty. Do not use.
