Product reviews: Easy Order Window Inserts Online

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!

I ordered and installed 21 inserts in a 113-year-old county Museum and another 15 in a restored railroad station of equal age as the Museum. The savings for both buildings have been in the hundreds if not thousands of dollars. The installation was quick and easy. Only one has been wrong and it was my error, as I forgot the double-hung window was not split in the middle. I have recommended this company and their product to many people.

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

Received my windows yesterday. They look beautiful. They were very easy to install. Packaging was great and shipment was quick. Will update this review at a later time after evaluating effectiveness of temperature control.

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!

These inserts are so easy to install and look fabulous. They weigh nothing and are crystal clear. We used to avoid one room in our house because it was so cold, but not any longer. The customer service has been top notch as well. I made a mistake in my order and Scott, Eric and Jessica went out of their way to fix the issue quickly. I wish all companies were this responsive to their customers! Great product

I bought these back in 2005 and I’m still using them, they work as well today as when I bought them! These are a great product!

The folks here know their stuff and remember you months later. A real personal touch which is nice.

I purchased several dozen inserts for my home and they really do their job nicely. They trap the heat, remove drafts, and protect wood frames from humidifier moisture condensation. They install faster and look better than "plastic wrap" style window coverings. It's also significantly less expensive than replacing windows.

I'm very pleased with the product, the results, and the service. Highly recommended for cold Maine winters.

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.

These windows are awesome. we live in a duplex that was built in the 1600 and added on in 1843. We went through one of the coldest winters on record last year and was expecting huge heating bills. To our surprise, our bills were less expensive than the previous year and the house never had that chill you feel in old houses. the inserts stopped the drafts and kept the house a consistent temp all winter. Liked them so much we are ordering 16 more for the rental and feel confident the tenants will be comfortable. Thank you for this simple effective product.

Window inserts was a pleasure to work with.
They addressed all our concerns and did what ever they could to make sure we were happy with our order.
The conversations with their staff was always pleasant.
Great company to do business with.

We just received our 6 kitchen window inserts and they look fantastic, fit perfectly and absolutely have stopped all of the cold draft coming in through the windows. The ordering process was easy, they kept us notified of our order status and they shipped and arrived quickly and very well packaged. We have a 119 year old home we just purchased and decided to try these out before purchasing window inserts for the entire home. I have to be honest, we were skeptical about the claims but not any longer. We had a winter storm after placing these inserts, the temp was 17 and the winds were gusting at 60mph. I can't think of more extreme conditions to try these out in and not a single kitchen drape was moving from drafts coming in and they are remarkably clear. We will be outfitting the rest of the home, 40+ windows! but this is way less expensive than new custom windows plus we can retain and enjoy the beauty of the original windows and woodwork. I cannot recommend highly enough!!!!

I ordered WindowInserts for our museum. The building is a 108 year old single family home that has been converted to our County Historical Museum. We put the WindowInserts on 17 windows, some very large. They fit beautifully. The first month that we can record showed a 30% drop in our heating and electrical bills.The building is very tight and draft free. We are in Michigan where every little bit of help to seal a old building is welcomed.

I just received my order and popped them into the windows! They are all perfect and I feel warmer already! Thank you so much for calling me to clarify the split order. I appreciate your product and your customer service!

Will definitely be ordering again.

I love our windowinserts. You exceeded my expectations.
Jessica went above and beyond with excellent customer service. Our inserts arrived BEFORE the promised date. The windowinserts fit like a glove and provide a crystal clear view of our lake. This is the real deal, it's an affordable, well built, product. The windowinserts transformed our sunroom into a cozy, year round, favorite room, in less than one hour. Incredible product, great service team, highly recommend this product.
Thank you.

I ordered the inserts for the entire office and everyone is thrilled. So I ordered a number for the house and my wife is thrilled. Great product. Very helpful with ordering. Product arrived ahead of schedule and exactly as ordered. I could not be happier!

These window inserts will save you thousands over replacement windows and work better. If you have a Casement window they are a must have. I can't believe the improvement they have made to my homes comfort level.

I just received my inserts. All I can say is wow. A class act business. One that cares, and delivers exactly what you want. Thank you for a great experience.

This is the best thing I do for my historic home in uptown New Orleans. These window inserts really work well by keep me warm in the winter and save me lots of money in energy bills. I am going to recommend this to all my clients, neighbors and friends. The staff is very friendly and helpful too.

This might be a premature comment, but my wife and I noticed the difference immediately. Place the inserts in the whole house easy to install. Will update in a few months

The window inserts are very good quality, sized perfectly, and look great. I called the company with a couple questions and they were wonderful to deal with. One of the owners, Eric, went above and beyond my expectations to help me. I highly Recommend this company and their products.

Love these window inserts!! We live on a mountain ridge with winds up to 80 mph in winter. These inserts have helped keep our house warmer by eliminating drafts and keeping out the cold. I purchased 6 window inserts 2 years ago, then another 6 more and a door insert this year. Quality product and reasonable pricing. The staff are also very helpful and friendly. Thank you, Window Inserts. No more putting up plastic film!

I ordered 4 custom window inserts of all slightly different sizes due to living in an older house. The inserts were received in on time and perfectly wrapped to prevent any damage. All the inserts were numbered 1 through 4 as prescribed and fit perfectly! I cannot even tell that they are in because they are so clear and fit so nicely. Also, and just as important, I can already feel the difference in the room temperature. I would highly recommend WindowInserts and would definitely order from them again.

Thanks You!
