Don't be fooled by the glossy adverts. As another online reviewer has already stated, this is the worst company I have ever dealt with. Months after quoting for the job, after we paid our deposit, and after they had completed our on-site survey our entire order (for £14,000) was completely cancelled shortly before installation. This cost us a 3 month delay and an extra £10,000 to complete our project. Despite the extra time and cost this was ultimately a lucky escape from this company: when we sought the same product from an alternative supplier they refused to supply the same product that Alpine were going to supply because it didn't meet their safety or functional standards. Through slick online & magazine advertising this company is pitching itself as a high end aluminim window & door supplier, but in reality is nothing of the sort, just a uPVC 'white gold' outfit who have seen an opportunity to make some cash in the growing aluminium sector without any degree of quality or substance. There is every chance they will give you a very competitive quote, but accepting this could cost you a lot of extra money in the long run, like it did for me. Don't be fooled like I was. I would implore anyone to avoid this company at all costs.
