We ordered a Pella bay window several yrs. Ago from Lowe's and they measured it wrong, sent the wrong window, a real fiasco. Finally got it straightened out. Now we need new corner picture windows. We asked for a Pella Rep to come out and measure to make sure we didn't run into the same problem. They sent a Pella Rep. He measured. The windows came on Nov. 13,2015, but 3" too tall. I don't know how someone can measure that much off. I can see a fraction of an inch, but 3"?? Now we are being told that they are going to remake them but that LOWE'S has to eat the original window cost! How can this be Lowe's fault when Pella came out and measured wrong? This will be the last window we purchase from Pella. What a nightmare.
