In most cases, a sagging headliner requires a full replacement. The sag is caused by the deterioration of the foam backing, not a failure of the adhesive. Simply re-gluing the old fabric won't work, as there's nothing for it to bond to. A full replacement ensures a durable, long-lasting solution.
Pins leave permanent holes and can't support the weight of the headliner, leading to more sagging. Standard spray adhesives aren't designed to withstand the high temperatures inside a car and can either fail quickly or seep through the fabric, causing unsightly stains and wrinkles. Professional installation uses specialized materials for a clean, permanent result.
The time required depends on the complexity of your vehicle, but most standard headliner replacements can be completed within a single day. Custom projects, like starlight headliner installations, may take longer. We'll provide a more accurate time estimate when you book your service.
