Product Size and Pet Fit
Use the manufacturer’s sizing guidance for the pet and product. The rough cut is based on the pet-door frame, not the visible flap alone. Confirm the mounting height so the animal can pass through comfortably.
Door Material
Wood, fiberglass, metal and storm doors cut differently and may contain internal reinforcement or panels. A decorative or insulated door can be more complex than a flat wood slab. Some door types are poor candidates for field modification.
Wall Installation
Wall kits require an opening through interior and exterior finishes, insulation and possibly framing. Hidden wires, plumbing or structural members can affect location. Wall installation is a larger scope than a simple door cutout.
Weather Sealing and Trim
Exterior pet doors should seal around the cut edge and frame according to the product instructions. Exposed cut material may need protection from moisture.
For broader door problems or replacement, use door repair or the appropriate exterior page.
