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.

From start to finish, we were very pleased with our rep, Reed, and the other staff at the PDX will call! The inserts themselves are stupendous! We purchased six total for the noisiest, road side(s) of our home. The outcome was beyond our expectations! Not only did the three rooms that bordered the road become at least 70% quieter, the other end of our home did as well! I cannot recommend Indow inserts more! The technology makes sense to add the inserts rather than purchasing new windows. Great results and thank you! Paul and Paula Spilsbury

Brian was very helpful & informative. He helped me order the correct windows for my needs. They were shipped with the utmost of care & arrived ahead of schedule. Ultimately, the Indow Windows have been very helpful in muffling unwanted noises & they have helped save on our energy costs. Thank you, Indow Window!

We are thrilled with our Indow window inserts! I'd been on the lookout for a more permanent solution to leaky windows in our third floor living space. I discovered Indow on social media but since then have learned of friends who'd had Indow recommended to them by their rennovation contractor. The entire process went smoothly with friendly reps at hand to talk through questions during measuring, etc. They fit perfectly and help us to maintain the beautiful design of the windows on our 100 year old home! Highly recommend!!

For townhouse living, this solved my problem with noise from my neighbor's with my kitchen window. A considerable decrease of noise indeed! Measurements were a bit frustrating so I recommend using a laser measurement device and following directions to use a string for the diagonal. They look great and were easy to push into place. I highly recommend as an alternative to buying a new window.

The process could've been smoother with the sending of the measuring kit. There was a delay with weather in Oregon but then it felt like my kit was still delayed due to other reasons. Most new homes (like mine) have textured paint and it can also be inside your window frames. I measured everything out but I still have little tiny gaps due to the texturing. Not indows problem but just be aware you made need to sand or fill in those gaps yourself to get a perfect seal. I did the acoustic grade inserts and they have reduced some noise but they will not completely block or significantly reduce road noise. This is most apparent with deep or lower frequencies like truck exhausts or modified street racing cars that are quite popular these days. Taking the inserts out to open your windows isn't an easy task. The little metal hook they provide needs to be either bigger or you can attach something to it as a way to leverage yourself. Overall the process was average. I think they're definitely a good option for weatherproofing and some sound reduction depending on the type of windows you have. I would purchase again.

The process for ordering and installing the Indow Widnow inserts was so easy. They sent the measuring information and it had great instructions. The inserts were delivered by UPS was crushed on one corner, but the company had packed them well, so there was no damage. We installed them the same day. It works best if you have two people completing the installation. We felt the results immediately and are glad we spent the money to make our home just a little more efficient.

Our home was built in 1913 and has beautiful old wavy glass single-paned windows. I’m so glad we were told about Indows and didn’t have to replace the original windows. We live in Canada but had no difficulty placing the order and were very impressed by how accurately the company met its deadlines, including cross border delivery. The Indows inserts blend in perfectly with our home and the existing window frames. You don’t see them unless you’re actually looking for them. But what we did notice was how much warmer the rooms feel the minute the inserts were installed! I can’t speak to any heating bill savings because they just went in this week, but our home feels much, much cozier. Our contractor who took all the measurements and installed the Indows says: “Excellent instructional videos: clear and informative. Very impressed with the design and the product. Overall, the ease of installation is quite impressive. Working with all the staff at the company was great – everyone was very helpful.” I’m already recommending this company to any of my friends who live in drafty older homes and want to reduce their heating/cooling bills and do some good for the environment.

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.
