I first used Alumax in 2015 to put in a set double doors, the price was reasonable and they did a fantastic job with the insulation. Then last year I contracted them to change my windows for single glazing to double glazing. I didn’t want them to take out the frames or sills but to just replace the windows, which they did do and price again was very reasonable. I was also only getting the windows done one room at a time, when I could afford it

We really love you guys…. Shane and the crew from Alumax interpreted our needs perfectly and with their professional crew were able to radically modernise Victory Venue. We couldn’t be more delighted with their service, product and pricing and highly recommend them, and indeed are planning other projects with them.

My name is Paul deLara-Bell, I build and develop property and I have been dealing with Alumax (previously Ashhurst Aluminium) now for 11 Years. I have found that their products are of a good high quality and if there is ever an issue (which is rare) they will fix it immediately. I have completed 11 new houses in this time and building another 3 which all will have Alumax windows and doors. Rarely do I shop around for the best price as Alumax are always very competitive but if I do on the odd occasion, Alumax normally are better priced or very similar. I have no hesitation in recommending Alumax as I know whoever buys their product, will be more than satisfied.

Alumax Systems understood what we needed and delivered our joinery right on time. Their joinery is constructed of top quality aluminium with a good selection of colours. The double locking system on the doors gives us extra security. They even installed our cat door for us. They have a prompt and efficient after sales service. We would happily recommend Alumax Systems.
