Terms of Service

These terms apply to your use of this website and to estimates and work booked with WFC-SF LLC, doing business as Sioux Falls Window Films Co. (“we,” “us”). Last updated: October 20, 2026.

Using this website

The information on this site is general. Window film performance depends on your glass, exposure and the product chosen, so it is not a promise of results for your property. We may update the site at any time.

Free estimates

Estimates are free. When you book, we come to your property, measure the glass, talk through your goals and prepare a written quote. We may leave a sample of the film you choose so you can see it on your own windows.

  • Online booking is available Monday through Friday, 9:30 AM to 5:00 PM Central.
  • Please give accurate contact details and a correct service address.
  • Appointments are confirmed by email. Our office may also text you from (605) 252-9854.

Rescheduling and cancelling

There is no fee and no notice period to cancel. To cancel or reschedule, call us at (605) 252-9854. You can also use the link in your confirmation email or email info@siouxfallswindowfilms.com.

Quotes and payment

A quote describes the film, the windows covered and the price. Quotes are typically valid for six months, at our discretion. Work is scheduled only after you approve the quote. Installation dates depend on weather, site access and product availability.

  • Deposit: large projects require a 50% deposit before work is scheduled.
  • Payment: full payment is typically due at completion, unless we have agreed to other terms in advance.

Warranties

Window film products carry the LLumar manufacturer’s warranty for that product. Our installation workmanship is warranted for the same length of time as the LLumar warranty on the film installed. Warranty details are stated in your quote or invoice.

Limitation of liability

To the extent the law allows, we are not responsible for indirect or consequential losses arising from use of this website. Nothing in these terms limits rights you have under South Dakota law.

Privacy

How we handle your information, including text messages, is explained in our Privacy Policy & SMS Terms.
