Hi guys, I'm looking at composite doors and I had in mind £500 would do the job, but it seems there are tons of brands which have no proven reputation and lots of horror histories after a couple of weeks researching on google. I'm looking for a long term quality door, but I was hoping to not spend much, but perhaps what I want is not possible. The 2 brands that come up a lot is Solidor and Rockdoor, but comes with a higher price tag. if I can't find any alternative to them that can offer quality and peace of mind, so be it, I'll have to spend more. If there are well know manufactures/installer that you guys could recommend, then I would be very happy I've gathered some information and it seems there are a few things to take into equation: South facing door, sunlight and door/frame expanding Darker colours tend to fade after a while, especially red Solidor has timber core, while Rockdoor has foam core. I don;t expect someone to come and pierce my door, but Solidor would have an upper hand in my opinion. Rockdoor carbon fibre seems to only add rigidity to the frame Low profile aluminium thresholds are prone to draught and water leak in some situations, perhaps use a regular door frame all around Does the letterbox affect much the insulation? I would like to have a Yale Conexis L1 smart lock in place. It seems any regular multilock system can do it as long the middle of door handle and the cylinder are 92mm apart I've found http://www.rightdoor.co.uk/ to sell Rockdoor installed in London for £1117 VAT inc http://www.rightdoor.co.uk/rock-door-ultimate/vermont/plain-glazed which so far is the cheapest I've come across online and I've seems a few success histories with them on the forums. http://www.phglazingsolutions.co.uk/ doesn't give prices but seem to have good reputation on checkatrade.com which I like, this shows transparency of the business. I could not get quotes yet from Solidor as their installer finder system is not working on their website. What prices should I expect from a basic door like the Vermont on the link above? There are a few other brands/shops that I've come across but I'm not sure what to say, these are my findings: http://www.hormann.co.uk/ high quality, perhaps better than Rockdoor and Solidor but very expensive https://www.compositedoorshop.co.uk/ saw some people recommending them, but I've no idea what door brand they use, I'm afraid of low quality chinese imports https://www.valuedoors.co.uk/composite-doors Rockdoors are about £1350+ and some reports that they are not good, they seems to be just a broker in the end https://www.abbeywindows.co.uk/upvc-doors/ultimate-composite-doors/ not sure if the ultimate door they sell is actually Rockdoor http://www.heritagetradeframes.co.uk/ just another composite seller or manufacturer, not sure if they are any good https://www.trade-upvc.co.uk are based in South London, that is the only reason I mentioned as I'm planning to visit their shop http://endurancedoors.co.uk/ have very good website and marketing material, no idea if the doors are also any good? The brochure has a lot of information http://endurancedoors.co.uk/resourc...a89d998c/endurance_doors_brochure_low_res.pdf http://www.compositedoorprices.co.uk/solidor-composite-doors/ seems to use other websites to give prices, not sure if they are just another broker? http://www.rocksolidoors.co.uk/component/virtuemart/solidor.html the only website so far with Solidor prices Apologies for the long post, perhaps I'm thinking too much about what would work for me, but considering the costs I think it is worth one I decide to go ahead to get the best I can for my hard earned money. Could you guys please share your thoughts? I would really appreciated it!
