Screen Door Pet Door Installation — Professional Pet Door Installation for Sliding Screens, Swinging Screens, Lanais, Porches and Enclosures

Whether your pet needs access through a sliding screen door, a swinging screen door, a screened lanai, a porch enclosure, or a three or four-season porch, Portal Pros has a professional installation solution. We carry two screen door products purpose built for screen applications, each designed for a specific type of screen setup. Our licensed and/or insured installers handle the fitting so the result is clean, secure, and built to last.

Security Boss Pet Screen Door For Sliding & Swinging Screen Doors Attaches to the bottom corner of an existing screen door frame, securing along the bottom rail and either the left or right vertical rail depending on your door's configuration. Designed for screen doors that are already framed and in a track or on hinges. No full frame required on all four sides. The pet door cutout is made in the screen material and the Security Boss unit attaches to two sides of the existing frame for a clean, stable installation.

SB4 Screen Dog Door For Lanais, Porch Enclosures, 3 & 4-Season Porches, and Framed Screen Panels Designed for installations where a complete frame is present on all four sides of the opening, such as a screened lanai panel, a porch enclosure bay, a framed screen section in a 3 or 4-season porch, or a standalone screen panel in a fenced yard. The SB4 mounts into the frame on all four sides and replaces the screen material in that section with a solid, framed pet door unit. Available in White and Dark Bronze to match most aluminum screen enclosure framing.

What Is a Screen Door Pet Door Installation?

A screen door pet door installation cuts an opening in an existing screen panel or screen door and installs a framed pet door unit that your pet can push through independently — without tearing the screen, without you having to open the door, and without compromising the function of the screen itself.

Screen pet door installations are fundamentally different from door mount, wall mount, or glass installations. The screen material is the substrate, not a structural element — so the installation method focuses on attaching to the surrounding frame rather than cutting through a rigid panel. The right product depends entirely on what kind of frame surrounds your screen: whether it's a sliding door frame, a hinged door frame, a full four-sided enclosure frame, or a fixed screen panel.

Portal Pros installs screen pet doors into sliding screen doors, swinging screen doors, screened lanais, porch enclosures, three-season and four-season porches, screen rooms, and framed screen panels in fenced yards — professionally, cleanly, and backed by our craftsmanship guarantee.

Screen Setups Portal Pros Installs Pet Doors Into

Sliding Screen Doors

The most common screen pet door application. Your sliding screen door rides in a track alongside your sliding glass patio door and the Pet Screen Door installs directly into the lower corner of that screen door frame. The unit attaches along the bottom rail and either the left or right vertical rail of your existing screen frame, and a cutout is made in the screen material for the pet door opening. Your screen door continues to slide normally. Available in White and Dark Bronze.

Swinging Screen Doors

Hinged swinging screen doors are common on back doors, garage entries, and side yards and are also compatible with the Security Boss Pet Screen Door. The unit attaches to the bottom rail and either the hinge-side or latch-side vertical frame rail depending on your door's configuration and where you want the pet door positioned. The door continues to swing and latch normally after installation.

Screened Lanais

Screened lanais, particularly common in Florida and other warm-weather states, typically consist of aluminum framing with screen panels spanning each bay of the enclosure. The SB4 is the right product for lanai installations. It mounts into the aluminum frame on all four sides of the panel section where the pet door will be installed, replacing the screen material in that section with the SB4 unit. Available in Dark Bronze with Black Screen, White, and White Frame with Black Screen, matching most standard lanai aluminum framing colors. Multiple customers have noted the SB4 blending seamlessly with their existing enclosure framing.

Porch Enclosures and Screen Rooms

Screened porch enclosures and screen rooms follow the same framing logic as lanais, aluminum or wood frame with screen panels in each bay. The SB4 mounts to the four-sided frame of the specific bay or panel section where pet access is needed. If you have a porch that is fully enclosed in screen and want your dog to move freely between the house and the porch or the porch and the yard, the SB4 is the right solution. Contact Portal Pros with photos (email to sales@theportalpros.com) of your enclosure and we'll identify the right panel location and confirm compatibility.

Three-Season and Four-Season Porches

Three-season porches typically feature screen panels or combination screen and glass panels that can be opened or removed seasonally. Four-season porches are more permanently enclosed but may still have screened sections or screen doors providing access to the yard. Both configurations can accommodate a Security Boss screen pet door. The right product depends on whether the screen section has a four-sided frame (SB4) or whether a framed screen door is already in place (Security Boss Pet Screen Door). Send us a photo (sales@theportalpros.com) and we'll assess your specific setup.

Screened Gazebos and Outdoor Structures

Framed screen enclosures around gazebos, pergolas, outdoor kitchens, or pool areas follow the same installation logic as lanais and porch enclosures. If the frame is present on all four sides of the screen panel where the pet door will be installed, the SB4 is the right product. Portal Pros can install into aluminum, wood, and composite screen framing depending on your structure.

Fenced Yard Screen Panels

Some homeowners use screened fence panels or framed screen sections within fenced areas to keep pets in specific zones while still allowing air flow. The SB4 can be installed into any framed screen panel in a fence or barrier where four-sided framing is present, giving pets access through the barrier without an open gap.

The Two Products — Understanding Which One Is Right for Your Screen

The most important thing to understand about screen pet door installation is that the two Security Boss products are not interchangeable, they are designed for fundamentally different frame situations.

Security Boss Pet Screen Door

Attaches to: the bottom rail and one vertical rail (left or right side) of an existing framed screen door.

This product is for screen doors that are already in a track or on hinges, sliding screen doors and swinging screen doors. The pet door unit mounts into the bottom corner of the existing door frame, using the bottom rail and one side rail as its anchor points. It does not require a four-sided frame to mount to, just the bottom and one side. A cutout is made in the screen material in that corner area, and the unit is secured to those two frame members. Available in White and Dark Bronze.

This is the right product if you have:

• A sliding screen door in a patio track
• A hinged/swinging screen door on a back or side entry
• A framed screen door of any kind where the bottom and one side of the frame are accessible for mounting

SB4 Screen Dog Door

Attaches to: all four sides of a framed screen panel or enclosure bay.

This product is for installations where a complete frame surrounds the opening on all four sides, the top, bottom, left, and right. It is designed for screened lanais, porch enclosures, screen rooms, gazebo enclosures, and any fixed framed screen panel. The SB4 replaces the screen material in that section of the frame with its own framed unit, mounting to all four frame members for a solid, permanent installation. Available in Dark Bronze with Black Screen, White, and White Frame with Black Screen.

This is the right product if you have:

• A screened lanai with aluminum bay framing
• A screened porch enclosure with framed screen panels
• A three or four-season porch with fixed framed screen sections
• A framed screen panel in a fence, gazebo, or outdoor structure
• Any installation where all four sides of the opening are framed and accessible

Not sure which one applies to your setup? Send us a photo (sales@theportalpros.com) of the screen area where you'd like the pet door installed, interior and exterior if possible, and we'll identify the right product immediately.

Why Choose Portal Pros for Screen Pet Door Installation?

Two purpose built products for every screen application. The Security Boss Pet Screen Door for framed screen doors, and the SB4 for lanais, enclosures, and fixed framed panels. We carry both and install both and we'll tell you which one is right for your specific setup before you spend a dollar.

Professional installation that preserves your screen system. A screen pet door installed incorrectly can pull away from the frame, leave gaps, or compromise the integrity of the surrounding screen material. Portal Pros installers are trained in both screen pet door products and install them correctly the first time.

Durable, outdoor-rated construction. Both Security Boss screen pet door products are built for outdoor use with aluminum framing, UV resistant materials, and heavy duty screen material rated for active pets. These are not flimsy plastic pet doors. The SB4 in particular has a strong reputation for lasting for years in harsh outdoor conditions, including the salt air and humidity of Florida lanais.

Available in finishes that match your screen framing. Dark Bronze, White, and White Frame with Black Screen options are available to match most standard residential and lanai aluminum framing colors.

Works for all pet sizes. Both products are available in multiple sizes to accommodate dogs and cats of all sizes, from small breeds through large breeds. Contact Portal Pros with your pet's shoulder height and width and we'll confirm the right size.

Licensed and/or insured installers nationwide. Every Portal Pros installer is vetted, trained, and insured. Your screen enclosure is in professional hands.

Craftsmanship guarantee. If there is ever an issue with our installation, we make it right.

How the Screen Pet Door Installation Process Works

Step 1 — Measure & Quote Contact Portal Pros with photos of the screen door or screen panel where you'd like the pet door installed, along with your pet's shoulder height and width. A photo of the frame and surrounding area, interior and exterior, is all we need to identify the right product, confirm compatibility, and provide a same-day quote.

Step 2 — Product Selection & Scheduling We confirm whether the Security Boss Pet Screen Door or the SB4 is right for your setup, recommend the appropriate size, and schedule your installation. Most screen pet door installations are completed in a single visit.

Step 3 — Professional Installation A licensed, insured Portal Pros installer arrives and makes a precise cutout in the screen material at the correct height for your pet's shoulder measurement. For the Security Boss Pet Screen Door, the unit is secured to the bottom rail and one vertical rail of your existing screen door frame. For the SB4, the unit is mounted to all four sides of your enclosure frame. The surrounding screen material is trimmed cleanly and the frame is secured.

Step 4 — Final Test & Walkthrough Your installer tests the flap, confirms the frame is secure on all required sides, and walks you through the product before leaving. Most screen installations are complete in one to two hours.

Screen Pet Door Installation — Frequently Asked Questions

What is the difference between the Security Boss Pet Screen Door and the SB4? The Security Boss Pet Screen Door is designed for existing framed screen doors, sliding or swinging, and attaches to the bottom rail and one vertical rail (left or right side) of the door frame. It does not require a four-sided frame. The SB4 is designed for lanais, porch enclosures, and fixed framed screen panels where all four sides of the opening are framed. It mounts to all four frame members. The right product depends entirely on what kind of screen setup you have.

Can a pet door be installed in any sliding screen door? Most standard residential sliding screen doors are compatible with the Security Boss Pet Screen Door, provided the bottom rail and one vertical rail of the frame are accessible and in good condition. Send us a photo of your screen door and we'll confirm compatibility before you order.

Can a pet door be installed in a screened lanai? Yes. The SB4 is specifically designed for screened lanai installations and is the most popular product for this application, particularly in Florida. It mounts to the aluminum bay framing on all four sides and replaces the screen material in that section. Available in finishes that match most standard lanai framing colors.

What if my screen door frame is wood instead of aluminum? Both Security Boss screen pet door products can be installed into wood-framed screen doors and enclosures as well as aluminum framing. Your installer will confirm the right fasteners and approach for your specific frame material.

Will the pet door damage my screen enclosure framing? No. The installation requires small fastener penetrations into the frame members the product mounts to, but the frame itself is not cut or structurally altered. The surrounding screen material is trimmed cleanly at the cutout edge.

What size screen pet door do I need? Measure your pet's shoulder height from the floor to the top of their shoulders and add 1–2 inches. Measure the widest point of their body and add at least 2 inches. Both Security Boss screen products are available in multiple sizes. If you're between sizes, size up. Contact us with your pet's measurements and we'll confirm the right size.

Can the SB4 be installed in a three-season porch? Yes. Three-season porches with framed screen panels are one of the most common SB4 applications. As long as the frame is present on all four sides of the section where the pet door will be installed, the SB4 is the right product. Send us a photo and we'll confirm.

Can a screen pet door be installed in a porch with both screen and glass panels? It depends on the specific configuration. If there is a screen panel or screen door section with a four-sided frame, the SB4 or Security Boss Pet Screen Door can be installed there. For glass panel sections, see our glass dog door installation page. Contact Portal Pros with photos of your porch and we'll assess the full setup.

Do you install screen pet doors nationwide? Yes. Portal Pros operates a nationwide network of licensed, bonded and/or insured installers. A professional in your area will contact you within 24–48 hours of placing an order.

Can the screen pet door be locked? Both Security Boss screen pet door products include a closing panel or cover that can be used to block the opening when not in use. These are not keyed locks but rather manual covers that prevent unsupervised access when needed.

Is screen pet door installation a good DIY project? The Security Boss products do include installation instructions and are more DIY-accessible than glass or wall installations. However, improper installation, particularly of the SB4, can result in gaps around the frame, screen material pulling away from the cutout edge, or the unit sitting unevenly in the panel. Professional installation ensures a clean, secure result that holds up to daily use.
