Frequently Asked Questions

AI
Most protectors are designed to be cuttable. Measure the width and depth of your current sill, then choose a product that meets or exceeds those dimensions so you can trim it for a precise fit.
Clear plexiglass or PVC protectors are ideal if you want to preserve the original look of your woodwork while preventing scratches. Solid colors are better for updating the decor or hiding existing damage.
It depends on the adhesive used. Many use temporary double-sided tape or pressure fits. Always test a small area or use painter-friendly adhesives if you are renting.
