We purchased the windows from Lowe's through a salesperson Vince. He came to the house, explained the products, the process, etc. We were very happy with what we heard and the price as well - we have shopped at Lowe's for years, and Vince was very personable and straightforward. The installation was performed by a subcontractor, and Vince told us all of their contractors have worked extensively with Lowe's and were very good. The installation was to take two days or three, depending on how long it took to install the large double sliding door. The first and second days went very well, and most of the regular windows got installed. The afternoon of the second day and the third day, they installed the two sliders. There were two bay windows left (which are made up of three and four separate windows separated by a vinyl strip in between). Well, turned out they couldn't install the bay windows because the separator strips that were ordered were wrong size. It would take two weeks to get them in. So three weeks goes by and the installer called to say the strips were in - he proposed doing it in two weeks because he was busy with other jobs. We said that was too long, so he worked it in the next week. As he got one bay window done and moved on to the other, he realized that the reordered strips were also the wrong size. So a new order had to be placed, it took three weeks for them to come in, and again he was busy and wanted to wait several weeks to finish the install. He managed to get back within two weeks, got the windows and strips installed, but we had to leave in the middle of this. When we got home and he was gone, we realized that he had not re-trimmed out the bay windows with new cedar trim but used the old wood that was partially rotted. He also left nail heads exposed, etc. We called Lowe's, and Vince came out to the house (mind you we are now several months into a project that was supposed to take two or three days). He agreed that the job was poorly done and called the installer. The installer came back, redid the trim work and was beginning to caulk the trim and the windows when it started to rain. He said he would call us that night to reschedule a time to finish since he couldn't caulk in the rain. He never called back, and several calls to him went unanswered. Because I had to get the trim work painted, I finished the caulking and filled in the nail holes myself. Through all of this, one of the other issues was that the lockset for the double slider sticks when you lock it, and one handle on the outside was peeling paint. When Vince came out to check out the problems with the trim, he agreed the lockset needed replacing. He said he would order it and the store would call when it came in. I waited about three weeks, then started calling the install dept at the store. I talked to several different people each time who said they would check on it and get back to me. Except for one exception, they did not call me back, so I had to keep calling. It seemed no one would take responsibility to get this taken care of. Finally, a man told me that they had ordered the wrong lockset, it had to be reordered, and they would call when it got to the store. After three weeks, I started calling again, and again went through the whole process of trying to track this down. Finally they said it had been reordered again and would be delivered to our house. It finally came (mind you this is now the end of August, four months later), and it included just the outside handle plus two additional outside handles with locks in them that did not go to our door. They did not send any replacement for the inside lock set mechanism as promised. I sent a complaint email to the Lowe's website complaint dept, who just sent it on to the store, who did contact me but basically had no resolution to this. The manager was very apologetic, and he assured me, as several other stall had, that our's was an unusual case and these installs generally go very smoothly. So I am not sure what was so unusual about our install, except for the big double slider, although the two bay windows were actually the biggest issue. Regardless, what is interesting to me is that no one from Lowe's came out to check on the install job (until much later when things were going very wrong and at our insistence), no one did a "punch list" to finalize the job and make sure everything was ok, no one gave us any warranty information, instructions, etc. for the windows. So I just hope that these windows hold up for awhile and we don't have problems with them. I also hope the sticking lock set on the big slider doesn't give out, because I can't see these people fixing it in any timely way. The other thing that is interesting to me is that our neighborhood is made up of houses built in the early 70's, and people are moving in and redoing these houses because it is a good area. Most of the houses still have those old single aluminum windows that need to be replaced. During the install, no less than fifteen different neighbors asked us who was doing the install and how it was going. We reserved judgment as the job wasn't finished, but as the time went by, we have been very clear with anyone who asks, don't go down this road with Lowe's - it's not worth it. My sense from dealing with the store and then the corporate complaint dept is that the company is just too big, the communication is terrible, no one is accountable, and they don't have a good handle on their subcontractors. And once the initial install is done, they are moving on, and you are chasing your tail. And that's too bad because I have always been a fan, and we still have two bathrooms and a kitchen to redo, so I guess that work will certainly go someplace else as well. I do have to say that we are basically happy with the windows, and the price was very competitive. From what I can tell, the Reliabuilt double pane window is a quality product and more than adequate for our temperate climate.
