"I hired STL Windows and Doors to replace 28 storm windows on my home because they were highly rated. 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. Thankyou!"

FAQs for egress window service projects in O Fallon, MO
The cost to install an egress window is $3,900 on average. This cost can be as low as $2,500 or as high as $5,300, depending on the window size, the number of egress windows installed, and the glass quality.
Double-pane windows average between $200 and $500 per window, whereas single-pane windows are more cost-effective at $100 to $400. More luxurious triple-pane windows are more expensive, ranging from $300 to $800 on average.
It can take up to three days to install an egress window. The window installation team will typically spend the first two days excavating the land where the window will go. If you’re replacing an egress window, it will be spent cutting the foundational wall to accommodate the window, if needed. Often, a window inspection is required to verify that the window was sized and installed correctly.
An egress window is similar to a regular window. However, this type of window opens fully to allow people to escape the home or rescue personnel to enter the home if an emergency occurs. Egress windows are required in all finished basements before they can be considered a living space.
Not only does an egress window add value to your home, but it’s also a basement requirement in most areas. Egress windows offer a 70% return on investment, making them a worthwhile purchase and installation. In addition, most building codes require an egress window to be used as an emergency exit and entrance. Therefore, it is a necessary addition to meet building codes.
There are a few ways to save money on egress window installation. First, choosing pre-fabricated windows instead of custom windows can help dramatically reduce the overall cost. In addition, skipping window extras, like customized frames or window film, can help save money on the price tag without sacrificing the window itself. You should also shop around to multiple window installers to find the best installation deal without sacrificing the quality of the window.
