Product reviews: Easy Order Window Inserts Online

Thank you so much for our windowinserts we have used them in our porch screens and it has made a wonderful outdoor lounge to sit in during the winter months with sweaters and blankets.....we love them and it makes all the difference in our freezing Canadian winters.

Also thank you for your wonderful service and alleving my worries and concerns. [First time making a purchase from a nonbox store...

I just wanted to drop you a note saying how happy I am with the window inserts. They fit great, and the drafty kitchen is now cozy. So easy to measure and install.

Thank you and happy holidays!

Received my latest utility bill it has gone down about 10 dollars so far so good. The whole house has the inserts and they work great. As some of you know Iowa is cold and windy most of the time in the winter months. So if you have a draft coming through your windows purchase this product really works.

I bought the inserts (six so far) for all the windows in the bedrooms. They have resolved long standing problems with my single pane windows. I have them inserted between 1 inch to 4 inches from the outside window panes. I am going to purchase more for the basement windows. The cost for all six inserts was less than what it would cost to replace ONE window.
Thank you for your product and quick delivery.

The inserts function exactly as advertised, and they earn very high marks, along with your excellent customer service.

Many thanks!

What a great product and company! I bought 9 inserts in Oct of 2015. I live in cold northern Vermont, and a house with very good insulation. These inserts are 100^% as advertised. Great looking, fit, quality of frame and plastic are Top Notch. Always have great interaction with customer service! Thanks for providing a great solution.

We cannot say enough about this company. We have had these Windowinserts for over 10 years and they are great. We use them in the winter and they make a big difference in warmth and still look great. Nice folks too and excellent customer service..

Love, love, love my Window Inserts! I have 2 large drafty old windows in my historic home. For years I have wanted to get storm windows but the cost was prohibitive. These inserts installed in a snap and they look great. Eric and his team are the BEST! Their customer service is second to none. They are very responsive and helpful. And my order was in my house in a week from my placing my order!! Thank you!

These are a fantastic product. The custom fitting according to my measurements is absolutely PERFECT.
It seals my drafty sunroom which has eight storm two-pane windows and nothing else for insulation. I put these in and presto! No more draft. It allows the sun to heat up the room nicely.
I made an error in measurements for one window, and Jessica solved my problem immediately. Not only that, she came up with a two-insert solution for the storm door, and saved me a lot of money for the item AND the shipping.
I really love it when things exceed my expectations. Both the window inserts and the customer service do just that.
Thank you Windowonserts!

Good afternoon! We received all our inserts and got them installed last night. Thank you again, we already felt a difference in the temperature of the room within minutes of them going in! Your company does amazing work, and thanks so much for the replacement for the dented one, We will keep it as backup.

Arrived this morning
I put them in and they are PERFECT
I want to THANK YOU for a job WELL DONE

We received our window inserts today. The packaging was perfect. The inserts were numbered correctly. The first one was installed in a matter of seconds and the others immediately after. We ordered enough for our bedroom and bathroom. I look forward to seeing if they help with the drafts. So far the measuring, ordering, and installation has gone well.

I ordered these for my home which has been in our family since it was built in 1968. The windows are original and they are aluminum. At this point in time replacing them would be a real hassle and my mother likes the way the house looks as is. I ordered 12 inserts and even have them on basement windows. I am so happy with them.

I purchased my Window Inserts last year and love them. They help reduced my heating and cooling cost and are barely noticeable.

The team at Window Inserts is considerate and responsive, I enjoyed working with them. Would definitely recommend.

Windows Inserts are a great product! They are easy to order and install. Above everything else they do there job. They look good and keep the drafts out. Having a townhome in the northern part of New Jersey on top of a mountain called for help and I got it from Window inserts. I highly recommend the product. I have ordered 7 so far and I am very happy with the whole process.

I just installed the 3 window inserts that I ordered, so easy to put in and the tan color matched my windows . Love them will be ordering more before next fall.

ordered windows very easily thru customer service they were very helpful the product is very nice they are working excellent i would buy more without hesitation if i needed more, they really work period don't wait to order winter is coming to an end and why should you not be comfortable !!!

I ordered the window inserts based on other reviews and agree with everyone. These are a wonderful energy saver, we noticed an immediate improvement. In spite of having newer double pane windows, we had noticeable cold air coming in around the bottom of our windows. That was virtually eliminated with the very easy to set in place inserts. Eric called to review our order, made a couple of changes and ensured they were delivered on a tight line we had. A builder visited our home and was very impressed, he had not seen anything like these before. We are very pleased.

Extremely pleased with the performance of these inserts on a 70 year old house! Even during single digits in the North Georgia mountains snow storm the house remained toasty warm and no draft. The difference is remarkable.

I would rate you 10 stars if that was an option! From initial ordering to the finished product, I am extremely pleased. (updated)

Very happy with your inserts. Fit perfect and look great. I mistakenly ordered the wrong size and they sent me replacements without charging me for the inserts or shipping. A great company to do business with and a great product. Thank you so much.

These are fantastic. Overnight was minus 10 oF. Saved money right out of the box. Thanks. No drafts.

The window inserts make the windows look as if nothing has been added to them; and they do keep the cold draft out in MN winter time. Thanks for the great product.

I’m really happy with the window inserts. I had to delay the delivery and it was delivered perfectly in time, just as promised. All window inserts fitted well and checking my electricity bill I found out that energy consumption went down 40%. I’m curious to see how much it will be in winter.

I received the window today. It fit like a glove, I could feel a reduction of heat coming thru the window right after I put them up. I am going to add 4 more windows tomorrow. This is an excellent product and very reasonably priced. I am very happy with them .

No More Drafts! No More Drafts! No more Drafts! The very first thing I noticed once I installed all 23 Inserts was that the drafts were gone. I also realized my windows have been costing me over the years. I got the inserts last night and had them all installed in about an hour, it was very easy to install them. It was cool last night so I could really tell the difference once I got all the inserts in. Today was warm 78°, and with temps like that my house is usually up above 78° before 3pm, today it never went over 76°. I already know these inserts are going to save me money. The packing was above standard, there is no way any of the inserts could be damaged unless something catastrophic happened. The inserts are a quality built item. I don't foresee any quality issues. The polyvinyl has insulating properties as well, because the first thing my wife noticed is she can't hear the outside noise she usually hears in the morning. There is a true measurable temp difference between the windows alone and the windows with the insert installed. My windows were between 65°-68° last night before I installed the inserts, about 15 min after I installed the inserts I measured the temp again and it was 73° using an infrared thermometer. The AC/ Heat was not on. That's significant. Well this is only my first impression. I will write another review once we get into the dead of winter. I expect I will be equally as impressed. I'll also report savings as I have tracked my energy use for about 5 years so it will be pretty accurate.
