To begin with, I have been in exterior remodeling for over 15 years, and owned my own Contracting company for 7. I have installed hundreds of windows of half a dozen different brands. This past spring I ordered 21 vinyl windows from 7D industries. They had a black exterior and white interior. I was also replacing siding, soffit/fascia and gutters, so everything was scheduled to work in order.

I rented a dumpster, JLG Machine and scheduled for support with another company owned by several friends, due to the size of the job. The first 3 windows we opened were scuffed and scratched beyond use. I contacted my supplier, who contact 7D. After several days 7d finally answered and said they were sending a couple items to clean the windows. I requested they send someone to do the repairs, and they tried to put me off until July.

I asked for a refund of my money, and again had to wait for a response. They finally sent someone to do the repairs and he took 6 windows without telling us, because they were too bad to repair on site. After 3 weeks, I finally had all of my windows. Between lost time, dumpster rentals and rescheduling a machine, I lost thousands of dollars. When I requested some compensation in some type of refund, I was ignored. I recommend contractors and home owners steer clear of 7d. I can think of at least 4 brands I have had better experience with.

I do not recommend seven D industries windows.we have a new construction home and this is the first winter for the windows. contacted them in November when window would not close. that had many excuses why they could not send anyone out to look at why we are having this problem. also Eliot will never answer phone calls or return phone calls. i have just received a email stating that room temp and cold window will cause water and ice. I think that we need to focus on the first problem of getting the window latched.

The only reason I gave your company one star is because I could not post my review otherwise. We built a new home and moved in February of 2021. From the get go we had condensation on the inside of our windows. This fall when my husband was making sure all of the windows were locked he found that he could not lock them. We have been dealing with Eliot since the fall and are just getting the run around.

No one has come to look at them and now "because it is winter" they won't send anyone out. Right now we are in a very cold weather pattern and now have ice on the inside of our windows. When speaking with our builder, who has built over 350 quality homes he said he has been receiving other complaints of the same problem. He only suggested this company due to the supply shortage of Anderson Windows.

He is done with this company. Eliot has excuse after excuse for our problems. We will continue to follow through on this issue. Our time and money is valuable and we are not satisfied with our windows, but especially unsatisfied with their lack of customer service. DO NOT BUY WINDOWS FROM THIS COMPANY.

7d industries door was put in my house. It has leaked air from day one. My contractor whl construction could/would not fix it. Avis Building supply got me in contact with 7d industries. 7d industries has only told me how to fix with all the reasons in the world why they can not send a tech. I would not recommend this product to anyone.

As a retail lumber yard we have come to rely heavily on 7D to meet the needs of our customers with a well made, quality, affordable vinyl window option. I have sold thousands of these over the past 15 years and installed numerous ones personally and have always had great success and almost never any issues or call backs compared to some larger "brand name" window companies! Great value and affordable window options without sacrificing quality! I would recommend to anyone.

Never bought through them but I have got sent there to work once through a temp agency. Let me start off by saying I can see why they have such a high turnover rate. The people in there don't train you & expect you to know how to do everything expected of you from the moment you walk in there. And when someone finally does come to help you they teach you the wrong thing then you get in trouble.

Not to mention there's like 2 bathrooms in the whole huge factory and they're all unsanitary to the point I'd hold it til I got home. My recommendation is. DONT WORK THERE. You'll thank me later for this

As a Salesman in the Building Supply Industry, I have come to rely on 7D lately. They have great windows, lots of options for my customer's, and their service is outstanding! So many other window company's have let their lead tiimes get out of control, my customers can't wait 2 or 3 months for windows. 7D can deliver much quicker, and I've had no mistakes with my orders.

I am proud to say that I have been selling 7D windows for almost 3 years. THEY ARE MADE IN HOLIDAYSBURG, PA USA! The Company is fantastic to work with, stands behind their products & provide EXCELLENT customer service! Many of my customers are repeats, telling me they love their 7D windows!

Thanks to my new Seven D windows, my furnace runs constantly and my house is freezing. My casement windows do not close. They are bowed. The lock mechanism can not engage. Customer service and communication has been horrendous. They sent the wrong size windows three times, which was a nightmare to coordinate during the build. The screens are shoddy compared to the Simonton windows we had previously purchased. Wish we would have stuck with Simonton but a middle man had convinced us to go with Seven D.

General contractor and have been waiting 10 weeks for 2 windows and nobody has any idea what is happening with the windows. Can't get any answers. Unacceptable.

I have a window warrant issue. I have left 3 messages at the warranty department over the last week and no returned calls. No one ever answers the phone, just get voice mail. Very poor customer service after the sale.

7D has been incredible for my company and my contractors. Customer service is outstanding and the quality of the product speaks for itself. I am always given the help I need in a timely manner. If you are looking for a company to fit your vinyl window needs, I HIGHLY recommend Seven D Industries.
