In total, I bought 30 Pella windows from Lowes. This was less than 3 years ago. When temperatures dip below thirty degrees the windows can't stand up to the cold. In the winter months we had to wipe down excessive water that created mold several times a day. To make matters worse, the most problematic windows were in our children's bedroom. We are completely dissatisfied with how poorly these windows have performed. Even more frustrating has been the total lack of accountability by either Pella or Lowes. I have spent hours calling, emailing and meeting people from Pella and Lowes. Everyone agrees that the water is excessive and the windows are not performing as they should. But no wants to accept responsibility. Honestly, we feel cheated. We feel like we were swindled. We trusted Pella and its reputation for quality. We relied on Lowes' assistance when we placed the order. These windows were a major investment. And in less than three years we have already had to replace 10 of the 30 windows so our kids aren't sleeping next to wet moldy windows. I hope this review saves more people from the costly mistake we made. Buyer beware of Lowe's and thermastar unless you live in the south or a very warm climate these windows are terrible.

Installed these window just like the instructions said to. These windows have so much leakage that when it's around 10 degrees moisture freezes on the bottom edges of top & bottom of windows. Pella keeps telling me my humidity is to high. We run a dehumidifier & humidity is @ 40 percent & we still have this problem. I have tried to get Pella to come, but they want to charge a service fee. I could go on but you get what I am saying.

The sales person did he part and was a great gentleman. We gave him rough opening measurements as directed. The windows were to be no more than 1/4 " off our measurements. They were special order. Only three windows out of twelve were made accurately . Some were off by as much as a whole inch! We had to add wood to make them fit at all before they could be leveled and squared up. The frame it's self was not square on the twin window. The screens of three fell out before they were installed . Peg for one screen not there at all. Hole in one screen. One not tucked in the bottom. Maybe we should have ordered aluminum instead of vinyl. The two doors fit perfectly! Every window has a bead of condensation all the way across now that temps have dropped outside, at the bottom along where glass and plastic meet. They are suppose to be filled with argon gas. Right! We put low expansion foam around the windows after installation , so should not have any air leaks that way. Should have gone to Spahn and Rose! Hind sight is always 20/20.

Installed by Professional , they never had any problems with pella before. of

Had to make adjustments of some type for every window but one. Three were replacement and the others new construction, because of new siding also. They look awesome with such a wonderful job of installation!! He even made new trim outside around the replacement windows by cutting PVC board to fit precisely !

I have installed several of these windows since 2005 as I go around rennovating my house. It is a simple matter to pop out the old wooden windows and install these new windows. I think they are very well made and the ones I put in 2005 are just as nice as the 2 I put in last month in 2012. I like that Lowes stands behind these windows and that I can order custom sizes. They come very carefully packaged and with complete instructions. After you do one window you can see exactly how to install others and you can do a better job than many installers by taking your time and using the best materials for shims, insulation, foil tape, caulk and paint. If you are hard on your windows by opening and closing several times a day, you may need more expensive windows, but if you want good durable vinyl windows that will last with reasonable use for years then you can't go wrong with Pella windows.

Last Pella windows I had were great. These new ones are far from it. Their service was rude and I would never buy another of their products. period. Obviously they're capitolizing on their past reputation to peddle inferior windows. 25 years ago Pella was very good.

I had Lowe's install Pella windows in my home in Pittsburgh, PA late last year. After their contractor finished, I realized that he had caulked closed and covered with aluminum trim all of the weep holes in the windows. (These are the little holes that allow water to get out of the window frames. If these are plugged, the water finds its way into the wall cavity and can severely damage the structure.) I contacted Lowe's and the installer and pointed out to both that I had found one of the Pella Installation Manuals that came with the windows and that the manual indicated clearly in BOLD print that the installer should NEVER caulk or cover these holes. The installer arrogantly told me that he was an expert, was the best Lowe's had to offer, and that Pella did not know windows as well as he did. I confirmed with Pella that the way the windows were installed has VOIDED my warranty. After 3 months of waiting and MANY calls to Pella, the local Lowe's store in Monroeville, PA, and Pella and Lowe's corporate headquarters, the situation has not been corrected. This "professional" installation by Lowe's continues to allow water to infiltrate my walls. The condition has damaged paint on the interior and exterior walls and I recently noticed a musty odor at one of the windows. I have also been suffering from a sinus and lung infection that has all of the symptoms of exposure to mold. The most unbelievable part of the whole experience ... this incompetent installer is still working for Lowe's installing windows! Lowe's explained that they cannot find anyone qualified who will do the job for the same money this person will. BEWARE OF LOWE'S

Installation of the replacement window by DIY Homeowner went pretty easy... well, after we figured out Pella sent us the wrong instructions. The window is a slider-type. I do notice the trickle of air through the weep holes that someone else mentioned. It doesn't really bother me, though. The lock sometimes catches and you have to fiddle with it a minute to get it to lock. Overall, the window is decent for the money we paid, and it sure is a whole lot better than what we had before (20+year old aluminum with wierd "fur balls" growing between the glass).
