I hired STL Windows and Doors to replace 28 storm windows on my home because they were highly…read morerated. I was told that the windows would be fully custom to fit my existing custom interior windows, however, the storm windows I received are not custom and do not line up with my existing interior windows (see photos below). Honestly, I just wanted this fixed as it degrades the look of our home and is not what I ordered. What the company will tell you: 1. They tried to remedy the situation, but the company they use is no longer making storm windows so there is nothing they can do. 2. They apologize if the windows are not aesthetically pleasing or do not meet my expectations (disregarding the fact that they are not what I ordered). 3. They pride themselves on customer service, their reputation, and their customer's satisfaction. What I will tell you: 1. When I alerted them to the issue, they said, "It is what it is." They also told me that the storm windows only came in a 50/50 split (and not custom). I contacted the supplier myself and confirmed that the windows are available to order in custom sizes. When I told the company this, they said that they had reached out to the supplier and since they were no longer making storm windows, there was nothing they could do. I asked if there were other solutions, such as contacting another supplier, but I never received an answer to that. They also claim that I didn't tell them of the issue until the job was complete, but I told the installer (who happens to be the owner's sister) at the beginning of day two and her fiancé (the salesman) came out at the beginning of day three to see what the issue was. The job was not completed until the end of day three. I did not correspond with the owner until I filed complaints and contacted a lawyer. 2. "Apologies" aside, I must now pay another company considerably more money to fix the issue caused by STL Windows and Doors. 3. Their actions do not align with priding themselves on customer service. To outline a few of the particulars (without going into too much detail): they've blamed the original salesperson who no longer works for the company, they lied about the windows not being available in custom sizes, they then blamed me after I found out that they are available in custom sizes, a window was installed broken and has not been fixed. Please SHARE this with family and friends to help them avoid losing money to false promises. Thank you!

We had a very poor experience with another company when researching windows and installation and…read morewere a bit cynical of contacting another business. However, the process of obtaining a quote was indeed as easy as Zen Windows website makes it out to be; check out their website and watch the videos. I completed their form with the number of windows, approximate size and the requirement that the windows must meet a minimum efficiency. A reply was quick and thorough and above all easily understood and answers to questions were immediate. Dennis provided all the information needed should a permit have been required. Once accepted, Kevin came out within a few days to take specific measurements needed for ordering the windows. Within just over a month, we received a call asking if the installation could take place within 48 hours as they had an opening. Ed, Jimmy and Daryl were the installation crew who arrived promptly and you could not ask for a more conscientious and professional team. They seemed to get along and worked well with each other. Care was taken to protect floors and carpet, the installation and operation of the windows was explained, and clean up was meticulous. I had planned to shampoo my carpets after they were finished and Daryl did such a good job of cleaning up the floors I did not have to vacuum first! We had 6 windows replaced and opted for the Endure EN600 series double hung, Energy Star Certified windows. These windows were installed on a warm day in rooms that get the afternoon sun and it was immediately apparent that the sun gain was much lower than the previous windows. The wind is gusting today and there are no drafts! The total cost was a bit above some of the other estimates but after our previous experiences as well as the ease of the ordering process, the personable and professional installers- much less the quality of the windows- it has been well worth it.

Their seasoned installers were very professional, prompt, and respectful of our home. They worked hard to replace our entire two story home in one day before bad weather was supposed to hit the next day.

I would definitely recommend them to anyone wanting the best customer service and no pressure sales with a great buying experience.
