DIY Window Treatments: No Contractors Required

If your windows are letting in too much noise, or drafts, or light, you need an upgrade. Living with unwanted light and sound, especially when you're stuck inside, can make you feel out of control and not at home in your house.

The most common window treatments are:

  • Adding curtains or blinds, which either block some light, or all light and some sound
  • Getting replacement windows
  • Replacing the windows yourself, if you are a skilled DIYer

Curtains, blinds, and window replacement can all require contractors or professional installers coming into your home. They would need access to any windows you want to upgrade, and in the case of replacement windows, they would need to access your wall, opening it up before doing any repairs or updates.

Window Inserts vs Window Blinds Installation

A better option is diy window inserts which can be installed from the comfort of your house to add privacy and energy savings without blocking your windows. If you want more control over the light and noise coming through your windows, but still like the way they look, think about adding window inserts.

DIY Window Inserts

Our window inserts can all be self installed. They just push into the interior of your window frame without mounting hardware or altering your original window. The window insert is custom made to fit your window precisely and mailed to your home or business so the whole interaction is contactless. We even have a contactless measurement process.

All of our diy window treatments block noise and drafts, but some grade types have extra benefits, like translucent panel for added privacy or UV protection to stop wood floors and furniture from fading.

Once the window inserts are installed, you can still add blind or curtains—they're a great way to dress up any room. With diy window inserts, you won't need to rely on curtains for privacy or noise control, so you can add whatever style you like.

How to Measure & Install DIY Window Inserts

  • We ship you a laser measurement kit (thoroughly cleaned between each use)
  • You measure your windows at home
  • Enter window dimensions into our online portal (our proprietary software and in-house window experts check the dimensions to ensure a perfect fit)
  • We create your custom window insert & ship it to you
  • You install it at home by pressing it into your window

Your window measurements work for each of these grade types: standard, noise-blocking, UV-blocking, privacy-grade. You can decide which grade of custom window insert you want at any point.

Window Insert Cost

The cost of our self-install window inserts depends on the size of your window and the grade type you choose. A standard-sized window averages $368 or $31/sf. When you choose to install yourself, you are skipping installation fees and the trouble of construction, and you're also making the entire process contactless.

If you'd like to start with an estimate of your diy window treatment cost, head to our window insert cost calculator. Enter your approximate window dimensions and whether you want our standard insert or our window insert with added noise blocking into the calculator (remember you can change it later). This will give you an idea of how much your insert or window project will cost.

Don't be afraid of buying an older home with single pane windows. This company has you covered. Their inserts are super high quality and fit well thanks to the laser measuring kit they send. Highly recommended!

We purchased three Indows to reduce drafts and noise in our bedroom, which faces the street. The improvement was immediate. Our house was built in 1958 and although we have exterior storm windows we didn't want to replace the windows outright due to cost and architectural consistency. These were an excellent solution.

Indow inserts were easy to measure, order and install. They've provided great insulation for old single-pane and stained glass windows in an antique home. We can significantly feel how much better the home holds heat.

I ordered two Indow inserts for my home. They are doing a great job, entirely happy with them and the ordering process.

I can't say enough good things about this product and company. Our house is 101 years old and the sidelites next to our front door are single pane ancient wavy glass which means when it gets very cold (Chicago temps) we can have an inch of frost covering the INSIDE of our windows. I was desperately searching for a solution so our front vestibule was not so cold and a friend recommended Indow. The process could not have been simpler and the temperature difference it has made is off the charts.

I have several historic single pane gridwork mullion windows. They're beautiful but have almost no thermal protection. Indows proved to be the perfect solution to preserve these windows while getting the thermal comfort we need. They were easy to install and work perfectly!

Amazingly easy to install even the safety chain holders. I. Noticed an immediate sound level difference and the room atmosphere became more solid feeling and pleasant. They also gave an insulating feature to the window drafts are non existent! The house is 50ft off a State highway that is heavily traveled in warmer months I'm confident the indows will handle it. I'm very pleased!

We ordered the acoustic inserts to help with road noise, and we've been sleeping so much better with them!

We used the windows inserts in our skylight. They are great! They the horrible drafts and noise out and were cost efficient. My only comment would be to provide better measurement and installation instructions for skylights specifically. It took us a lot of guessing and research to measure and install because skylight directions were not provided and the windows install guide doesn't always apply to skylights. Other than that though great product and I would buy again!

Our home was built in the late 1800s and we have spent a lot of money over the last 20+years restoring it.We did not want to replace the windows with modern windows because of the cost and originality. But the single pane windows come with a price also. the main reason we purchased the Indow window inserts is because of the condensation on the inside of the windows.We would literally have a take a towel and wipe them down every morning in the winter. There would be a puddle on the sill,and wood and water dont get along to well. SO we looked into the best solution to our problem and found Indow. Was reluctant to spend that much money but am super glad we did!! They have been installed now for over two months and our condensation problem has been virtually eliminated.!!! AND our furnace does not run as much as it did before. Over all it was money well spent!! The process was a little scary at first but they have a simple formula. And our contact person,Reed was awesome. Answered any questions i had and was always available.

Used to block interior side of a garden window in the the kitchen. Without insert, cold air literally poured into the kitchen making a winter jacket almost mandatory when preparing meals or washing dishes

Highly recommend! The team (Brian) took time to help me figure out the best solution. They were made and delivered faster than expected. It was very rewarding to install them because I could feel the cold air get squeezed out as they went flush against the single pane of glass. Solid quality and great fit.

My inserts fit beautifully into my 125 year old windows - many of which were 5 feet tall. Easy to unwrap and install. Great product and even better service! I liked the process of measuring the windows with a laser measuring tool which was easy to use and precise. The product came in good condition after shipping across country and was well marked. The customer support was excellent.

Received our Indow Windows and can tell they are blocking a lot of the noise we could hear. Right now the weather is mild, but hoping to notice a big difference when the summer heats up. Our house is in a historic district and we cannot change our windows. They are very drafty and thin glass. We only ordered two, but we are in the process of ordering for four more. Love that we don’t need to drill holes or anything and they just pop right in.

Every thing arrived in perfect condition, thanks to the very secure packaging. Windows fit as expected, although quite tight. After installation we noticed that the cold drafts were gone and the room felt a lot warmer. We are very satisfied with the product and the result.
