Product reviews: Easy Order Window Inserts Online

I bought window inserts from you about a year ago and am very happy with them and wanted to let you know. We have a large sun porch on our house that was built in 1910. The windows are single pane and it used to be unusable in winter. Today is very cold starting at 10 degrees with a wind chill that is below zero. I just opened the French doors and cautiously stepped into the room. Much to my surprise, it was very warm and comfortable to sit in. We also insulated the floor, but I attribute most of the change to your inserts.

Thank you for dramatically expanding the useable space in our home. The inserts provide great insulation and are attractive too.

Love these window inserts!!! We just finished a complete garage renovation. For 36 years I have covered the 2 windows with window insulation kits with the tape and the Saran type plastic wrap. I completely ruined the window moldings with all that glue tape. The reason for the kits was a deep windowsill that every bug in the world found delightful to visit and die on. It drove me crazy. When we decided to renovate the garage, we put on new moldings and I really wanted a product that would keep the bugs off the windowsills and look nice. I found your window inserts online and decided to give them a try. Best decision ever! Placing the window inserts in the windows were the very last thing we did in our 3 month project. It took less than 10 min. They fit perfectly, were really easy to install, and come already cleaned. We were worried that the inserts wouldn’t stay put. The design allows a tight fit and they don’t move. They look great. This is the first year that I am confident we will have no dead bugs on our garage windowsills. A great product from a good company!

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.

I am very happy with my purchase. It is so much warmer in my living room. My only regret is not having purchased these sooner. Chicago always gets days where it is bitterly cold and we would have to pile blankets on so we could just sit in the living room. Happy to say that I am not doing that today. Thank you

We own a historic 1833 plantation home that we’ve renovated into a charming B&B. With many original (and old) windows, preserving the home's character was a top priority for us. While we updated the windows, it was the Window Inserts from windowinserts.com that truly completed the transformation. The best part? You can’t even tell they’re there—they’re invisible, yet so effective. Our guests consistently praise how these inserts maintain the authentic charm of the home.

windowinserts.com went above and beyond to assist us, providing exceptional communication and a delightful experience throughout the process. Highly recommended!

I purchased 6 windows last fall. I wanted to wait until I went through the winter and summer months to make my opinion. I am so pleased with the window inserts. There is no drafts at all compared to what I used to have. In the summer my heat pump is hardly running. The money was well worth it. Thank You

I live in NH, and I am thoroughly satisfied with my window inserts which I purchased about a year ago. I live in an historic house that is 167 years old, and changing out the historic windows was not possible. The inserts fit snugly and keep my bedroom and study much warmer and quieter than without them. I was so happy with these inserts that I purchased some for my daughter to use in her newly acquired 1930s bungalow in MD. Now her study and living room are much more comfortable. I researched a lot of other companies but felt that these inserts were the best DYI items I could find for the price. Just do it. You will not regret this purchase.

I work for a University and our windows are like paper and we have COLD winters. This product has made a HUGE difference in our offices being much warmer. Our windows are very irregular in size due to being an old building, but the inserts fit pretty good considering (definitely not a manufacturer issue, but our old building). While the inserts are flexible, they are not flimsy and I found rather easy to get in and out. The gentleman that I worked with was fantastic about double checking my measurements, etc. and do everything he could to make sure we were satisfied. Great product and team!

I was looking for a more frugal manner to insulate seven windows in my mountain cabin without replacing the windows themselves. I had draft problems as well as single pane windows which you could feel the cold air penetrating from the outside and the heated air from the inside escaping out. Window inserts was the perfect solution. From ordering to the delivery the turn around time was around seven days and three days the second time when I came back and ordered more for my house! The product quality is very good and cuts are precise fitting like a glove if you measured correctly. The come well packaged. The level of customer service that you receive if you call the company is second to none. I wish more companies cared about their customers as this one does.
I couldn't be more pleased with the results. My cabin is warmer and stays warm even as the temperatures drop below freezing with my stove working less and even shutting off as the temperature is maintained. No more drafts and warm air is spread more uniformly within my 980sq ft of living space. Cost wise, compared to having to pay for dual pane windows with gas filled space the window inserts have saved me a couple of thousand at least. I am one very happy customer, thank you very much. Please support this small business.

Good day Eric. Just wanted to let you know that I have now seen the product and I am very impressed. I was concerned since the product was going to Canada but had no issues with International orders at all. Every part of the order went perfect from the ordering to the shipping to the packaging to the fit and quality of the inserts. First of all, the order was very easy to do, easy to measure and payment types offered were great. Second, as far as shipping, packaging was done extremely well so nothing would break, you took care of the shipping and all went great. Third, my wife installed the inserts with ease before I got home from work and everything fit perfect. The inserts are great quality. They look so good that you cant even tell they are there. Thanks again for the great product and experience ordering with you.

I wanna say, your product is amazing, i have 4 windows and ordered for two windows, what a difference, i am gonna be ordering for the last two windows soon, i live in a condo and we all have the same windows and have the same issues with the cheap windows. I have all my neighbors over and love them, they are also gonna order, i feel like a salesmen. Its an awesome product. Thank you

Received my order yesterday, just before the -21 degree weather. I am so impressed with these. The house is so much more comfortable. These are nice looking, fairly inexpensive, and exceeded my expectations on cutting winter chill. What a great product! Thank you

Very happy and warmer after installing ten inserts where most needed.
Gas boiler is now operating more efficiently. Because drafts are blocked and heat is contained inside the house the boiler is not constantly running.
Tip, save shipping box and cardboard separators to store inserts if removing in the summer.
Was pleasantly surprised at the quick turnaround time to receive the inserts after ordering. Highly recommended.

Order to delivery within 2 weeks. Great packing job. I installed 8 inserts in minutes. Great fit and immediate results in warmth and quiet. Exactly as advertised and now I just need to order more for the rest of our windows. I'll wait to do that with the cost savings I'm sure that I'll see from the ones I just installed. Good work guys and gals! You deserve success! Thank you.

We just want to say a huge THANK YOU for your service. We ordered window inserts from you over this summer and are very happy so far with the product. It has not been real cold yet but the inserts seem to be doing what they are supposed to. Thank you again for your help putting together this order for us.

I love my windows. They are easy to put in and look great! I will recommend Window inserts to my family and friends . Great people and great products!!

What an amazing product! I purchased window inserts for our screened-in-porch, replacing plexiglass. The inserts fit perfectly and were a breeze to install. Not only were they easy to install, they look awesome! In addition, I was quite impressed with the great customer service and prompt delivery of the inserts. I would definitely recommend purchasing your product to family and friends.

Dear Eric,

Just received my second order of 6 windows in perfect condition via FedEx and have inserted them. We are very pleased so let the cold winds blow.

Hope you're having a good season at North Star. If you make it to Vail, try to let me know.

Happy New Year!

We got our windows about 10 days ago and they are fantastic. I have been given your name out like crazy so if you start getting a lot order from Alpena Michigan, you can say Zen Fitness. They are fantastic. We are no longer freezing. Yeah they fit perfect easy to use. I put them in myself. Just wanted to tell you how wonderful there. Thank you very much and you guys have a wonderful day.

The window inserts are fantastic,
I ordered for a screened in porch. Now I can use the space on days when it is not freezing. They were easy to insert & the owners were super helpful as we were unsure of our measurements & called several times with questions. I highly recommend them, they look great & very affordable. Thank you for this wonderful product, good quality & good looking!

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...

Just want to tell you how pleased we are with the new inserts. They arrived promptly and well protected in the shipping box.
It was a piece of cake to place these into the windows and within a 1/2 hr. all 13 were in. We get a constant westerly breeze on the front of the house and had been experiencing a lot of cold drafts. The plastic storm windows with the double-sided sticky tape were a hassle to put in and looked terrible. The drafts are gone the inserts are almost invisible and we're sure we'll be saving on heating fuel during the winter. You have a great product. Happy Holidays. Ours is sure to be warm and cozy.

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!
