I was recommended to Alpine by a friend who had recently purchased from Alpine, for there new build. There job included a full house of windows and entrance doors, along with some Bi-folds. My project was very similar, with a full house extension, covering 2 stories and i wanted to replace all the windows in the property whilst the work was taking place.The price wasn't the cheapest but the 15 year guarantee and the fact i could see the product, made it worth paying extra. I visited the show room and placed the order and within 2 weeks i had a surveyor on site to measure and run through the details with me. i was then given a date which was 3 weeks after the survey, i did however receive a call a couple of days prior to installation to notify me installation would be delayed by a week as a machine had broken down. This didn't bother me too much as these things happen and other parts of my project have also been delayed and i would rather wait to have good quality product installed. The product was installed a week later and i couldn't be any happier overall. the installation team were friendly and tidy, along with lots of attention to detail included. My house looks great and my extension is now nearly complete - Thanks Alpine
