Products reviews

100% on website, customer service, delivery, and utility! I ordered a test insert for an old window installed in 1888. It was delivered 2 days early and packaged extremely well. I unwrapped and installed the insert in a few minutes - it fit perfectly. The view through the window remained the same and friends couldn't see anything different. I will be ordering inserts for many more windows. I am so pleased with everything about this product.

Love these inserts. They took about 3 minutes to install. Easy, nicely and a perfect fit!

I just got my replacement inserts.

I want to tell you that your company has incredible customer service. I have enjoyed every facet of this experience.

I have a smart thermostat in my bedroom that I can use to track furnace run time. The first night I installed the inserts, it was 10 degrees cooler than the night before, but the furnace ran half as often.

I will encourage everyone I know to try your product.

I ordered 4 of them about two weeks ago and got them in yesterday and they are amazing! I noticed a difference almost immediately! I plan on ordering 14 more tonight.

We purchased window Inserts for a rental property to maintain the beautiful windows in the home and to pass an inspection. The home was built in 1939 and has beautiful iron rod windows. To ensure the tenant would not be left with a drafty house, we purchased around 20 inserts. Let me start by saying the customer service is remarkable, professional, and knowledgable. The inserts fit perfectly and the house looks amazing and has decreased in the draftiness. We love the inserts so much, that we are in the process of measuring the windows in our home to alleviate the draftiness that we are experiencing. The inspector was so impressed with the inserts, that she is also going to tell other rental landlords about the alternative of replacing windows to maintain the home’s charm. The owner of the company is amazing and we recommend window inserts to everyone. We are so very pleased and happy with the product and look forward to experiencing the same kind of comfort in our own home.

My order was delivered today, right on schedule , packaged well and in perfect condition! It took me only about 5 minutes to install, they fit perfectly! I was quite impressed. I wish I had known of these a few years ago. I had some inner storms built by a local hardware, difference of night and day.

Purchased 6 inserts for three large windows, 60"x 60". Rather than repeat the superlatives of previous posts, with which I concur, I want to comment on the clarity of the view. I anticipated that there would be a reduction in the quality of the view, but it is perfect. I can't tell any difference between the windows with and without the inserts in terms of the view outside into my yard. I recommend the inserts unreservedly.

Got my order and put them in today! Wowww, I'm so thrilled. They feel durable, fit perfectly, and were a dream to install. No sign of the usual drafts at all. And I'm keeping the packaging for storing them in summer. You've got an excellent product here! I'm going to recommend them to all my old house owning friends.

Thank you!

I had the good fortune to find Energysavr Window Inserts on the internet. I ordered them for my entire house, found then to be perfect fits, easy to install and remove to clean the windows. Most important is that they stopped all drafts and cold radiation from my windows to make my house more comfortable than ever. Add to that the fact that the support service was excellent and gracious. Buy them.

Two years and running. The inserts have saved me about 30-40% a year on my electric bills. The inserts are still clear and my 3y/o hasn't been able to tear one yet. Not only have they saved me money, but they show me which windows are bad, especially when the wind blows. The insert bows inward or it vibrates when the wind blows against the window, but the wind doesn't transfer into the house. I'm so glad I got these inserts they saved me thousands of dollars vs buying new windows. Before I put these inserts in I couldn't keep my thermostat on 70 in the winter because the system would not shut off and the very expensive AUX heat would cycle on and off, that doesn't happen now. I can actually set the thermostat on 69 and be comfortable at temps in the teens and the dreaded AUX heat doesn't come on. In the summer I couldn't have the tstat set on 71-72 without the unit constantly running. That doesn't happen anymore either. I can now have my stat set on 71-72 and not only doesn't it stay on, it doesn't constantly cycle on and off either. These inserts are a bargain at twice the price. Thank You guys for thinking outside the box!

Love my inserts. They work and are extremely reasonable in price. Also the customer service is impeccable. They are a godsend to anyone who wants to save on their energy bills, and so easy to install. I would rate them the highest it goes plus plus. Like 5 stars++++

Excellent product. I had a few windows in a 100-year old house that allowed some air to seep in. These inserts fit nice and snug (but not too snug) and got rid of the draft. It was really the perfect solution to my problem. And I ordered another one for my last drafty window.

It's not sales hype! These things work! Our 102 year old home has some beautiful windows that we have no intention of replacing. I ordered a full house worth Energy$avr inserts (25). They came masterfully packed and undamaged. Each one fit perfectly to the proper dimensions I provided. The wife was worried how they might look with our 1/4 sawn oak windows but they look great (we got the brown frames). I know for a fact that these will pay for themselves in short order... I woke up to 5 degrees this morning and the rooms that I had finished servicing the windows on and installing the Energy$avr inserts in were noticeably warmer. IMO as far as investments in your home goes these are hard to beat. Thank you for an excellent product and timely delivery!

We are now using these for the fourth winter = they are fantastic!! Holding up well, Insulating great. No problems. I highly recommend these inserts!! And we live in a very cold area.

INSERTS FIT PERFECT AND ARE VERY NICE LOOKING (IN SINGLE PANEL APPLICATIONS THEY ARE BARELY NOTICEABLE). THEY ARE MANUFACTURED AND SHIPPED VERY QUICKLY. OVERALL THEY APPEAR TO BE A GOOD VALUE AND WOULD DEFINITELY RECOMMEND THEM !

This is an outstanding company. They are easy to work with and their product is amazing. They go out of their way to make your experience perfect each time. Thank you!

I work for the federal Government so, I am speaking from my own experience. I have had nothing but great customer service from WindowInserts, I have had the pleasure of working with Eric directly several times and he has been amazingly helpful.

I just received my order and installed my 5 inserts. These are great! The quality is fantastic and the installation was a breeze (no pun intended as now things are air tight!)

Immediate difference, perfect fit, easy install, no more draft. I bought these inserts and this is an honest review these things are awesome. i would like to be a salesperson for this company I have 100% confidence in the value these offer. could help save the planet, you get more than what you pay for......

I purchased 3 windows to see if they were worth the cost. It has been 3 years and i have not found any other windows that compared to the cost. Easy to install and easy to clean. I have just ordered 6 more windows to complete my first floor. LOVE THEM!!!

We have just completed installing inserts for all the windows in our camp in Northern NY that we use year round now. We have also put them in the screened large openings on our porch and over the french doors onto the patio. All the inserts have worked even better than we expected. Great customer service and follow through and helpful advise from Eric re how approach to some unusual needs. We have been showing to friends and neighbors!

The first order was for 12 awning window inserts. The fit is perfect and we just placed an order for ten more openings, We could not be more pleased!

This company is great! The window inserts are super. What a difference it makes in the house. No more drafts and are so easy to install. We will be ordering more in the future. Trying to do a little bit at a time. Before we knew about these we had storm windows put on for some windows downstairs. Needless to stay we still get drafts. So with that being said, I wish we had heard of these inserts earlier. However, we will be ordering inserts for the windows that we had storms put on. It only makes sense to get the best. These window inserts are the BEST!!

We have a 200 year old house where none of the openings are square. Window Inserts was easy or order from, afordable, and each insert flexes to the opening, so they all worked perfectly. We mis ordered once, and their customer service group was great. They have helped us to save money and use our old windows, while saving money!

Not only am I very happy with the product's strength, beauty and functionality, but they are very easy to install and adjust. No more using plastic film and two sided sticky tape that always leaves a mess behind, not to mention the hours it took to install and the annual cost of more materials. The only thing I'm sorry about is that it took me so long to graduate to the sensible way with these inserts. it was an investment I will never regret, and the customer support was awesome!
