Don't believe the clever marketing. The composite doors from Solidor come at a premium price but that is not reflected in the quality of the product. Doors not glazed properly in the factory so water gets in and swells the timber core. Lock mechs hammered into the slab because the machined holes for the gearboxes are too tight are the two most common production issues in my experience. That can and does result in a shortened life span of the multi-point lock mechanism. There is never a good time for the lock mech to fail, door unlocked and you have a security issue. Door locked and it may well all be scrap. Solidor customer service is atrocious. They will make it difficult to complain and force you to jump through hoops in the hope that you give up and go away. That is if they will deal with you at all which is quite rare. The warranty doesn't belong to the door owner, rather the installer (company or individual). The installer gets the warranty from their supplier which may be Solidor but more likely an intermediary company. You get to find this out later when your slab has split by the mouldings, swollen due to water getting in or has curled and is difficult to lock, draughty or both. I've worked in the double glazing trade for over 30 years (production, service, installation and survey) so hopefully have some idea of what I am doing by now. Hands up, I bought into the product being quality but it quite simply isn't. People keep asking for these doors which are marketed extremely well and it can be awkward trying to dissuade householders from what they think they want. Hopefully these words may go some way to making people think twice and consider other options, there are plenty out there. I have good customers (every single one is a recommend from another customer) that I have supplied and installed Solidor doors for over the last 7 years or so. Warranty issues that Solidor won't entertain means that I can no longer provide this product in good faith. Having to fill cracked door skins with worktop jointing compound (and colour matched silicone in some cases) in an attempt to prevent water ingress because Solidor do a great impression of a slippery eel is not my idea of good customer service. Not for me or my customers. Just to clarify I am a sole trader and do not charge enough to entertain absorbing the cost of replacing the door somewhere down the line. People like myself work for wages only, much the same as every employed person. Things do go wrong, sometimes more than we would like, hiding behind technicalities rather than honouring warranties is not good business practice in the long run. We all need to make a profit but the end user has a right to expect warranties to be honoured. From here on I will be strongly advising all of my customers to avoid Solidor composite doors.
