Choosing the wrong window film installer costs you twice: once for the bad installation and again to have it redone properly. The GTA has dozens of companies offering window film, from solo operators working out of a van to established dealers with manufacturer backing. Here is how to tell the difference and what to look for before you hire anyone.
Check Their Dealer Status
The single most important thing to verify is whether the installer is an authorized dealer for a major film manufacturer like Madico, SolarGard, 3M, or LLumar. Authorized dealers have been vetted by the manufacturer, trained on proper installation techniques, and can offer manufacturer-backed warranties. Non-authorized installers buy film from distributors and cannot provide the same warranty coverage.
At Proferred Film Solutions, we are authorized dealers for both Madico and SolarGard, which means every installation comes with a manufacturer warranty in addition to our own workmanship guarantee.
Ask About Their Film Brands
Not all window film is the same. Professional-grade films from Madico, SolarGard, 3M, and LLumar are manufactured to precise specifications and tested for long-term performance. Lower-cost films from unknown manufacturers may look similar at first but degrade faster, with issues like bubbling, discoloration, and peeling appearing within 2 to 5 years.
If an installer cannot tell you exactly which manufacturer and product line they are using, that is a red flag.
Look at Their Google Reviews
Reviews tell you what happens after the sale. Look for consistent themes: clean installation, on-time arrival, good communication, and professional results. A 5-star rating with detailed reviews is worth more than a 4.5-star rating with hundreds of generic reviews. Quality of reviews matters more than quantity.
Ask About Security Film Installation Specifically
If you are getting security film installed, ask whether the installer applies structural sealant around the perimeter. Many installers skip this step because it adds time and material cost. Without the perimeter seal, security film can be pushed out of the frame after the glass breaks, significantly reducing its effectiveness.
Get a Written Quote with Product Details
A professional installer provides a written quote that specifies the exact film product, thickness, manufacturer, coverage area, total cost, warranty terms, and estimated installation time. If you are getting a verbal quote with vague product descriptions, move on.
Verify Insurance and WSIB Coverage
Any installer working in your home or business should carry liability insurance and WSIB coverage for their workers. Ask for proof before allowing work to begin.
Compare Apples to Apples
When comparing quotes from different installers, make sure they are quoting the same film type and thickness. A quote for 4mil security film at $10 per square foot is not comparable to a quote for 8mil security film at $16 per square foot. The cheaper quote is not better, it is a different product.
