Pella Corporation

A few of the sections, the panes didn't quite line up. They came out and measured and ended replacing the windows at no additional cost. They were very professional and I appreciated them doing this. They always called ahead and arrived on time.

Unbeknownst to us the windows carried a warranty.  We were the second owner, but it covered us, regardless.  The windows had a history of moisture getting in between the sash and the metal trim causing rotting.  Our windows did not display that, but everything was replaced anyway.  (My subsequent searches showed there was a class action lawsuit that required Pella to replace the windows but apparently only if asked.)  Fortunately for us, we had 3 months left under the original warranty.  
Our windows consisted of normal crank-out windows for most, but we did have two very large sections (one on the main floor and the other in the finished walkout basement) that needed to be replaced.  These were four or five-window sections each, and the main floor had transom windows at the top.  Every window was removed and replaced in a half day.  They started at 8 am and were done just before noon.   Debris and old windows were picked up by mid-afternoon of the same day.
It truly was an amazing experience.  And, our product really did not show the symptoms, but they were replaced anyway.

The workers were prompt. I would recommend them to a friend. They couldn't have done anything differently.

It started off ok as I had contected Pella through http://www.pella.com/ they sent a salesman out right away.
I took time looked them up in the BBB ect. and decided to purchase.
On the day of the install 12/27/2012 is when thing started bad and have continued through 04/18/2013. (See review on Pella Windows & Doors 8700 FALLBROOK DRIVE Houston Tx 77064 for detail)
See what Pella neglected to tell me is that I was dealing with a franchise and that Installation warranty that Pella offers is not upheld.
Basically as of 04/18/2013 Pella has told me that my problem is with the franchise Pella Windows and Doors of Houston and that they will attempt to have the franchise send out another set of installers to fix the issues.
After explaining that I have had to sets of installers and 2 sets of doors and now major damage to my house including structural that I would like someone whom knew how to install a door. (See the doors were not installed even to basic constructionstandards let alone the Mfg instruction, which is 6 pages long with pictures.)
I was also informed by Pella that my Mfg warranty is void as the doors are installed incorrectly.
So what does a consumer do in this situation?
Warn everyone do not use Pella anywhere as Pella hides behinde the franchise when things go bad.
Oh and I think I am getting a lawyer.

They were fine. Everything happened as expected. They were on time.

They were on time; they came when they said they would. I?m still going through the process of collecting quotes for this job but I thought Pella was outrageously expensive. On the quote, there was only a grand total rather than it being broken down by individual window prices.

It is a national company and they arrange for a representative to come out and talk to you about what you need. They do some preliminary measurements and then they have a professional come out and do the measurements.

I was happy with the quality of the windows. I had a 20 year warranty for the windows, and when one began to leak, they said they would be happy to replace the window, but they would charge for service. The service fee would amount to over $400 because it is a large window, and I chose to not have the window replaced at this time.

Our home builder used a Pella storm door when the contractor built the house in 2000. The door has a twenty year warranty. This month we replaced our rear storm door for the second time under this warranty. Initially, I called the 800 number. About a week later, the company sent instructions for the warranty claim. After measuring the door, taking pictures, and completing the forms, I mailed the claim information to the company. About a week later I received a note to call to pay for the shipping of the replacement door. Once the door arrived, it did not have the pre-drilled holes for installation as the instructions called for.
