The short answer
Choose a window film installer who is licensed and insured, uses their own trained employees, measures your home in person, explains film options in terms of heat, glare, privacy and view, and gives you the warranty terms in writing. Avoid anyone who quotes a price without seeing your windows or promises the same warranty on every film and glass type.
Your checklist
- Licensed and insured. Ask for their Minnesota license number and proof of liability insurance. Sun Control’s MN license is IR702639, and we are fully insured.
- Employed installers, not subcontractors. Ask who will actually be in your home. Employed installers are trained to one standard and accountable to the company.
- An in-home visit before the price. Glass type, window age, sun exposure and seals all change which films are safe and effective. A good installer checks them in person.
- Film choices explained plainly. You should hear how each option changes heat, glare, privacy, UV and what your view looks like day and night, not just a product name.
- Glass compatibility checked. Some films are not right for certain dual-pane or low-E windows. Ask how they decide what is safe for your glass.
- Warranty in writing. Coverage depends on the film and your specific windows. Ask for the actual written terms and who handles a claim.
- Experience and reviews. Look for years in business, local references and recent reviews. Sun Control has installed window film in Minnesota since 1978.
- A clear, itemized estimate. Pane count, specific film, and any removal of old film should be listed. Sun Control does not charge for estimates.
Questions to ask on the estimate visit
- Which film do you recommend for these windows, and why?
- How will this film look from inside and outside, at night?
- Is this film safe for my glass type?
- Who will install it, and how long will it take?
- What does the written warranty cover?

Frequently asked questions
How long does residential window film installation take?
Most homes are done in a day. Larger homes or specialty films can take longer, and your installer will give you a time estimate up front.
Will window film make my house dark?
Not necessarily. Many residential films are nearly clear and still cut heat, glare and UV. Your installer should show you samples on your own windows.
Can window film be put on dual-pane windows?
Often yes, but not every film suits every window. A qualified installer checks your glass type before recommending a film.
Does window film help with fading?
Quality films block up to 99% of UV rays, one of the main causes of fading in floors, furniture and artwork. Visible light and heat also play a part.
Can I see out at night with privacy film?
It depends on the film. Reflective films give daytime privacy, but at night the effect reverses when lights are on inside. Frosted or decorative films give privacy day and night.
Is Sun Control an authorized window film dealer?
Yes. Sun Control of Minnesota is an authorized 3M and XPEL window film dealer, so the film we install is covered by the manufacturer’s warranty.
Does Sun Control check my glass before quoting?
Yes. We identify your glass type, number of panes and any low-E coating, and confirm the film is approved for that glass before we give you a price.
What warranty does Sun Control give on home window film?
A written warranty that covers both the film and our labor. Terms depend on the film and your windows, and you get them in writing with your quote.
Where are Sun Control’s locations?
Sun Control has five locations: St. Paul (headquarters), Plymouth, Rochester, Duluth and Hudson, Wisconsin. We have installed window film in the region since 1978.
