Product reviews: Easy Order Window Inserts Online

They are awesome and took 10 mins to install. Heated my living room by 10 degrees. I'm ordering more.

Thank you for exceeding my expectations.

We were looking for a quick, simple, reasonably priced solution to help seal the drafts around our old aluminum windows. We found the answer that checked all the boxes with EnergySavr window inserts. The inserts fit my dimensions perfectly and were fairly easy to install. Every panel fit very snugly and securely with little effort. I couldn’t be happier with the service I received from windowinserts.com. The owner even texted me after receiving my order with suggestions on minor modifications that would make the inserts a little easier to handle and install, plus save me about half of my shipping costs. Thanks for a great product and for great service.

What a great product you custom build and sell. Just installed four of them (48"X36") in my 30 X 40 insulated pole building . The wind this past weekend in Northern Illinois was 50 mph gusts and teens for temperature but could keep the shop at 70 Degrees. A few weeks ago before installation we had similar weather and could only maintain 60 degrees.

These were very easy to install although for a couple of the bad air leaking windows, I installed blocks to keep them from pushing out of the frame. So glad I found your product and took a chance and purchased. Very easy to order and install, and the shipping and delivery was very prompt. Thank you again for you fine product and service

We would like to rate your product and customer service at 5 stars. We have been telling all of our friends about your product I hope they contact like we did!

Wow, I LOVE the inserts!

I am so impressed with how easy they were for me to install, by myself.
So far, so good with them staying in place - and today will be a test because high winds are expected this afternoon.

I appreciate your customer service and I hope to add more in this 100+ year old house of mine with lots of windows.

Wanted to get you a big shout out for the window inserts.

I knew they would work, but not only worked, they actually exceeded expectations. I knew when I put up the first panel insert, I could immediately tell the difference. My central heat stopped cycling every 20 minutes, but went to every 45 minutes.

Thanks again!

Please tell everyone concerned about my measuring capabilities and my understanding of what the inserts are designed to do that the inserts arrived today and I put them up by myself. They fit perfectly. FYI I’m going to be 83 on the 14th of this month, which is of little consequence since I’m planning on living forever.

Five years ago I bought a house in Michigan that was built in 1880. It needed a lot of tlc but the windows with their wavy glass and original woodwork made me fall in love.

I found your company by surfing the web and took a chance. I measured my windows, entered my info on line, paid and pushed submit. I was a little nervous but excited too.

I received my large order of window inserts about 2 weeks later, from your company, and installed them immediately! I couldn’t be more happy with the way they fit and keep the cold air out!

I open my curtains every morning and they are not cold to the touch! They are warm! The air in my rooms is also warm! I am so very happy that I chose you to help beautify my old home.

Thank you from the bottom of my heart

Good morning. We received our window inserts, way up here in Northwest Maine! They have been installed for three days and they are AMAZING! The room is retaining heat better than ever. The difference was immediate. I can now relax on the window seat without draft, or the cold air that was emanating from the glass. We are very appreciative of the quality of the product and real customer service. You guys should get some kind of consumer award.

Thank you very much. Happy Holidays.

Well need I say they are the BEST item I've purchased in a while .. had a little son in laws help but they are astounding .. will see when we really get a big chill her on Long Island..

I placed my order one year ago yesterday but waited to write a review to see how well they really worked. The window inserts are perfect. I was very hesitant on purchasing these, however I am so happy that I did. Customer service is out of this world. I picked the wrong split, Eric noticed it and called ME before processing my order to let me know that I could save money and the inserts would actually match my window split exactly, if I went with his suggestion. My single pane windows in a two year old townhouse are worthless, the inserts have stopped the drafts, rattling screens, and the dirt that tends to blow in. I ordered inserts for 7 windows and didn't think about the basement window or patio door. I am hoping to order the last two soon. I have shown and recommended these inserts to friends and neighbors and they have been very impressed at the quality, ease of inserting, and how you don't notice the inserts. My heating bills have been reduced and I'm pretty sure that the 2025-2026 WI winter is going to prove a warmer house again.
Thank you for a great product that is made in the USA!

Wow! So much more than I thought! So sturdily made, so easy to use and makes so much of a difference. I bought for my screened in porch and I was able to install them all by myself as a 65 yo. The ordering was easy, direct contact with a representative who helped me so much. I love the numbering of items which eliminated the need to figure it out. Just love the entire process. Thank you Window Inserts!

My husband saw the ad on TV and we checked it out because we live on the southside of a northern Minnesota lake, and the north winds are brutal during the winters. Today, we put them in the windows for the 5th year in a row, and the savings is so well worth it, plus the warmth stays in the house instead of going out the windows!
And the service when we first ordered them! A++ One of the owners called me and asked if we followed the video to measure them...because they are custom made. So I told her the truth...my hubby knew how to measure. And yes, we'd do it the right way this time. Of course, they came perfect for our windows and quickly! We would recommend them, and have, to several people so far.

I bought three sets of inserts for original Andersen single pane casement windows as I did not like any of the options for replacement windows, That was 2019. They have held up just fine, cut down on drafts. I only remove them for cleaning as our NEW heat pump is either heating or cooling, no need to open windows

These window inserts are made exactly as I specified in my order and they are made well. Tight window inserts with no wrinkles. Frames are strong and fit well. Packaged for shipping very well. Nothing to dislike and a good price too.

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 am super happy with this product! I installed them the moment they arrived, which by the way was faster than I expected. They were well packaged and fit perfectly into my 6 living room windows. That night happened to be an unexpected cold snap, and I was so shocked at how comfortable I was in my living room. I had to check the outside temp a few times because I was so used to cranking up my heat on days like this. They look great too. Like they've always been there. Not to mention that I checked around and the price was great, and they are all-season which other brands aren't necessarily. Customer service is great. Eric had a question for me and I'm glad I got to talk to him as he gave me even more confidence in this product. It has saved me so much money and was so easy! I'm going to be recommending these to my neighbors who were complaining about their windows too!

Just received my inserts and they fit perfectly! Great design and easy to install! The brown color matched my windows as well. I can already tell they are working . House is tighter and less drafty! Thanks for a great product!

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

Living in far upstate NY near the Canadian border where we have winter. I received 14 window inserts yesterday for our year round sun room. The packaging was very good. Installation was easy and the fit is very tight. Immediately noticed that the room was quiet as it was a very windy day when I installed the inserts. I am quite sure I will use less electricity as a result but haven’t been able to assess that yet. I gave this review 5 stars but I would have given it 4.5 stars if I could have only because the windows are not crystal clear as glass giving a somewhat distorted appearance. The savings will offset this minor issue. Wonder if anyone else has noticed this. Very happy with the purchase and the windows are doing what I expected. Eric called prior to construction to check on some items with me which was great service. Happy with the purchase. Thanks

My house was built in 1920 and had many old-style storm windows that were broken when I bought it, which caused a ton of draftiness especially on windy days. Nobody makes storms anymore, and I didn't want to do the huge splurge of fully replacing windows, so I got these inserts and I could not be more pleased. They're very lightweight and surprisingly flexible, and fit snugly but not painfully tight in my windows. As I write this review, it's an extremely cold and windy day with gusts over 40mph and there is a massive difference in the draftiness-- and by difference, I mean barely any draft at all! I am beyond pleased and can't wait to see how much lower my heating bill will be this month.

If you need a cost effective, custom-sized option to help with draftiness or efficiency, I cannot recommend these inserts enough. They ship quickly, are incredibly easy to install, and have made a huge difference in my old home. My furnace kicks on less, there's little to no draftiness in my house, and the brown trim makes the inserts blend very nicely with the rest of the home. You wouldn't even notice them if you weren't looking for them.

Cannot recommend these enough!

Wish I ordered years ago. I'll echo others with the quality and fit. Shipping packaging was A+ After installing, immediately noticed a marked increase in warmth! Furnace runs less too.

Measured window openings and again the next day to make sure no mistakes.

Even though I'm pretty confident there is no actual air infiltration, we experienced an uncomfortable cold downdraft from the skylight tunnels in our kitchen and family room. I think it was just air being cooled up by the skylight and then rotating down into the room. I installed the inserts into the tunnels 12 inches below the skylights; I thought I might have to install some sort of support to keep them up, but they seem quite secure with just friction fit. The result is terrific, the downdraft has been reduced to almost nothing.

I have had the window inserts for over five years, they have added to my older homes comfort, took them out this past fall to clean them and reinstalled. The ordering process is simple and deliver was as promised. I would highly recommend them if you want a cost effective alternative to replacing your windows. Scale of 1/10 I would give them a 10.

I wanted to take a minute to let you know our order came today and I had the three windows installed in 20 minutes, including the one (2) piece unit. This time included removing the mini blinds and repositioning them after the window installation.

Your windows are awesome. They are made well, to my exact measurements, and as a result fit perfectly. Since COVID we have been generally unhappy with the work/products we have received anytime we have made home repairs. This includes the new Andersen windows that your inserts are no insulating properly as the windows themselves are very poorly made. It's nice to know that there are still people who take pride in their products and deliver on their promises!

Thanks again,
