Update on review of Aug 5th. In interim between install and repair, a piece of trim came off and…read morewas blown from balcony in wind. The Pella repair man came today (Aug 20th) to finish install and replace missing trim. He cleaned up a lot of the dirty prints left behind on trim and in caulk on install, but did not have correct trim to replace trim that fell off. Wish he would have been here to guide the installers. They evidently are not experienced enough to work independently and could use supervision. The trim that fell off was not the correct trim for exterior. With trim missing between balcony door and transom over the door, it shows that the gap between is about 1/8" on outer edges and widens in middle to greater than 1/4" wide, then narrows to about 1/8" on other side. Gave me a clue as to why the trim fell off. I would conclude that lower door frame was not shimmed properly to be set level. It will likely be a few more weeks before correct trim piece can be ordered and the repair completed. Other residents in the condo community have been asking, and based on my experience, I cannot reccommend Pella.

For the first time I realize I had been hearing a fair amount of outside noise (which I'd apparently gotten used to), because these windows/doors are soundproof; now I don't hear anything at all from outside! And even better, the windows are easy to open, and my sliding glass doors actually slide well in the track, and are not shaking and drafty when it's windy outside -- major improvements from my old, builder-grade, 20+ year-old windows/sliding door. Further, the service crew was excellent -- careful, kind, professional, efficient, and they cleaned up everything afterwards. Roger, the foreman, has been doing this work for almost 30 years, and Jose, who single-handedly carried in/out the windows/doors, has been doing this work for 10+ years. I didn't get the name of the quiet third service person who was mostly outside and on the ladders, also very efficient. fyi, they did mention that working on the 4th floor of our condos from ladders was a bit more challenging as the original builder-grade windows had been made to fit by being packed/taped in place from the outside, which necessitated them having to actually break some of the glass to be able to pull the old windows out. But they did it - and did it well. Finally, Shaun, the project manager who gave me my estimate and oversaw the project from estimate, HOA approval process, to completion, was great. Highly recommended.

Once…read morethe installation was finally completed correctly, the quality of the product itself met my expectations. However, the overall process was far more stressful than it should have been. My original appointment was scheduled back in February, but no one showed up, and when I called, I was told the appointment was not even in the system so they had to rescehdule. Then on installation day, the crew arrived with the wrong size and wrong color door, which delayed the installation and caused me to miss work. Communication throughout the process was slow, and I had to repeatedly call and request escalation before receiving consistent updates. Ironically, communication became much quicker when it came time to collect the final payment. While compensation was eventually offered, it felt like the minimum possible amount considering the inconvenience and lost time involved. In the end, the final product turned out well, but the scheduling, communication, and ordering issues made the experience frustrating overall.

We recently had some questions about the work and contacted the company, only to find that the Sam we knew had sadly passed. The new owners (Sam's children) seem to be just as qualified, caring, friendly, and eager to support customers. I can only guess they have the same ethic, and would highly recommend the company. They originally provided exactly the service requested, great quality, and value. I predict the next generation will continue to do so.

I like the windows, but the screens are deteriorating and I wanted the screens fixed (re-scree-ed). No more than 6 screen. They took a week to get back to me but only after I called. 100 bucks a screen despite a "Lifetime No Gimmick Warranty" on the windows. They said the screens are old- not covered. Apparently they don't understand the concept of "Lifetime" Anyway, the current owner won't even talk to me. A signed letter from Mr Sam Hammaker makes no difference. I guess he's no longer around. I wouldn't do business with this company but if you do, don't count on any warranty On more thing, the written response to me said that "no warranty was given" back in 2007. Anyone who wants to see the signed letter from Mr Hammaker or the big whole page "Lifetime No Gimmick Warranty" I would be happy to send a picture of both.
