Epic Truth About Warranty Coverage in 2020: Shocking Facts Revealed
Warranty coverage in 2026 sounds great on paper—until you read the fine print. Most homeowners sign off on warranties without realizing how many exclusions, conditions, and loopholes can void protection completely. At Thrush & Son, we’ve seen warranty coverage in 2026 turn into zero coverage because of small overlooked details. That’s why understanding warranty coverage is critical before you buy or install anything for your home. Warranty coverage in 2026 isn’t just a safety net—it’s a contract. Manufacturers build in rules to limit their liability, and if you break them (even unintentionally), you’re left paying for repairs out of pocket. Here’s the shocking truth about warranty coverage in 2026 and how to protect yourself.Storm Doors Can Void Entry Door Warranty Coverage
One of the most common traps with warranties is installing a storm door over a new entry door. Many manufacturers explicitly state: “Storm door installation voids warranty.” Another large brand adds: “Any damage caused by improper installation of a storm door or the installation of a non-venting, full glass storm door shall void this warranty.” So yes—adding a storm door can instantly kill your entry door warranty! Always check the fine print before combining products.Painting or Staining Can Void Your Finish Warranty
If you buy a pre-finished door from a big box store and paint or stain it without removing hinges and frames, you’ve likely voided the finish warranty. Manufacturers require full removal of hardware so every surface gets even treatment. Miss that step, and warranty suddenly disappears. Some warranties even limit coverage to “owner-occupied residential dwellings” only—meaning rental properties or flipped homes do not get a warranty at all. This is why you have to be sure to read every line.Transferability & Other Hidden Limits
