Snug Fit Guarantee

The Indow Snug Fit Guarantee is designed to help you measure with confidence and know we are here to support you. Indow boasts a 99.8% first time fit, so you can believe in yourself and our process. We look forward to bringing you comfort and quiet.

The Indow measurement system uses six dimensions to measure the inside of your window frame. These are entered into your measurement portal to calculate the shape of your window and allows us to build an insert with a near airtight seal.

SNUG FIT GUARANTEE ELIGIBILITY

  1. To be eligible for the Snug Fit Guarantee, you must report the presence of any of the following conditions. Failure to communicate these conditions will nullify the Snug Fit Guarantee. These conditions may cause fit issues if not communicated during the measurement process:

    1. Window frames with bows.

    2. Rounded corners or buildup in the corners due to paint or other debris.

    3. Obstructions in the window sill, such as existing window hardware or blinds.

    4. Irregular surfaces at time of measurement: textured material or uneven concrete such as grout or mortar joints.

      1. Installation of an IndowKIT in a window frame not made of wood or drywall.

    5. Inadequate frame depth:

      1. IndowONE inserts require ⅝” of flat, unobstructed space perpendicular to the window, or 1 ¼” behind blinds or similar where compression may be restricted.

      2. IndowKIT inserts require 1 1/2" of flat, unobstructed space perpendicular to the window.

    6. Inappropriate applications: exterior side of window, fireplace opening, door (Indow inserts are designed as secondary glazing to be used on the inside of the home or building and are unsupported for alternative applications unless express written consent from Indow is provided)

    7. Transcription errors, omissions, or negligence: duplicate entries for the same window opening when a second opening was intended

  2. To qualify for the Snug Fit Guarantee, you must only use Indow tools and processes to take the measurements and upload them to your Indow Dashboard as directed.

  3. Any errors or warnings regarding measurements which are presented during the measurement process must be resolved before finalizing your order.

If An Insert Doesn't Fit

In rare instances, customers may receive an insert that doesn't fit properly. In these cases, you will need to complete our warranty claim process and we will work with you to troubleshoot the issue and determine if the insert qualifies for modification or replacement.

IndowONE
Most issues can be solved with our Frame Fit Kit, which will be sent to you free of charge. If the Frame Fit Kit fails to resolve the issue, we will replace your insert free of charge, subject to a limitation of $2,500 per order. If you decline using the Frame Fit Kit, we may alternatively offer a 50% discount on a replacement insert.

IndowKIT
If any component of your IndowKIT does not fit correctly, we will provide a replacement for that component free of charge.

Replacements
In the event that a replacement insert or component is warranted, we may request updated window measurements (or a new template for specialty shape windows). If you measured with our Laser Measure Kit, we will send you a new one and waive the deposit fee.

Failure to provide updated measurements within 30 days of our request will invalidate the Snug Fit Guarantee.

If, after receiving updated measurements, we are unable to determine the reason for your fit issue, Indow reserves the right, but not the obligation, to refund your purchase price for the Indow insert(s) in question, as an alternative to replacement.

Any claims made to Indow must be made within 30 days of the shipment delivery date to qualify for the Snug Fit Guarantee.

Effective as of 8/5/2026.
