We have used Andersen for years, saving up and replacing our windows as we can afford them. They are, by far, my favorite company. Having dealt with two salesmen, I found both extremely professional and exceptionally helpful in picking out good designs for my funny, crooked house (none of our window or door openings are "square"; we have lovely trapezoids instead). The first salesman (no longer with the company), redesigned our landing windows, creating one of the most beautiful spaces in our house (another company had been completely defeated by the project). For our latest effort, Guy LaCroix spent forever helping me redesign our french doors both for aesthetics as well as security, and we love the results. Jim Eister does the measuring, and he is delightful. He always remembers our house (and the time I baked bread), and he as much as anyone is responsible for figuring out how to measure our strange windows and writing reminder notes to the installers as to what works best for our house. The installation went smoothly, done by two very pleasant gentlemen who found yet another installation tweak to reduce the number of hinge and lock holes needing to be filled. Mike Sharp came out and finished the caulking and helped tighten some trim (his work is beautiful). I also cannot say enough about the manager, Michael LeMoins. On our first installation (which was particularly tricky), Michael came out to our house more than once to check the progress and help trouble-shoot the trim. He was out again for our bay window job just to make sure there were no unforeseen problems. The few times when we've needed adjustments, Michael is one hundred percent determined to guarantee our satisfaction. The only downside is I now compare all companies to Andersen. Sadly, few ever measure up.
