# Automatic Pawport Dog Door in Vinyl Siding Wall in Derwood, MD Location: Derwood Services: - Pet Door Installation Completed: November 2026 Summary: Installed an automatic Pawport smart dog door through a vinyl-sided exterior wall, with a framed, insulated opening and a weatherproof cover, giving the dogs secure, hands-free access to the deck. Content: These [Derwood](https://www.allds.com/service-areas) homeowners wanted their dogs to come and go from the deck without someone opening the patio door all day. They chose a [**Pawport Smart Pet Door**](https://pawport.com/) and asked our team to install it through an exterior wall with vinyl siding. Installing a dog door in a wall rather than in a patio door keeps the glass door fully usable and gives pets a dedicated, secure entrance. ### Why Homeowners Choose the Pawport Smart Pet Door Pawport is a premium automatic pet door, very different from a traditional flap: - **Opens automatically** for pets wearing the waterproof Smart Pet Tag on their collar - **Steel construction with aircraft-grade aluminum doors** for strength and durability - **Dual steel deadbolts**, top and bottom, for security - **Weatherproof seal** when closed, keeping out drafts, rain, and pests - **Anti-pinch safety**: the doors open and close slowly and gently - **App control and smart home integration**, so you can manage pet access from your phone - **Available in several sizes,** for pets up to 100 lbs ### How We Installed the Dog Door Through the Wall A through-the-wall pet door installation takes careful planning, because the wall holds framing, insulation, and often electrical wiring. Our in-house team: 1. **Protected the home**: covered the floors, patio door entry, and deck with drop cloths and plastic 2. **Inspected the wall**: measured and marked the opening to the Pawport specifications, then checked inside the wall for wiring and other obstructions 3. **Cut the opening** through the drywall, insulation, and vinyl siding 4. **Framed the opening** so the wall stays structurally sound 5. **Insulated and waterproofed the tunnel** with insulation and flashing tape to block moisture and air leaks 6. **Installed the Pawport door**, then leveled, aligned, and tested it according to the manufacturer’s guidelines 7. **Sealed the exterior** and added a rain hood to protect the opening from the weather 8. **Cleaned up** and removed all debris The installation was completed in a single morning. ### Already Bought a Pet Door?
