Dog Door Installation FAQ | Glass, Wall & Door Mount | Portal Pros

A dog door, also called a pet door or doggy door, is a small opening installed in a door, wall, window, or glass panel that allows your pet to move freely between indoors and outdoors without needing you to open the door for them. Most dog doors feature a flexible flap that your pet pushes through, which then closes behind them to maintain insulation and security.

Dog doors offer major benefits for both pets and their owners:

• Physical Health: Pets get more exercise and fresh air, reducing the risk of obesity and joint problems.
• Stress & Anxiety Reduction: Pets gain independence and freedom, which lowers anxiety and reduces destructive behaviors like scratching and whining.
• Owner Convenience: No more rushing home or waking up at night to let your dog out.
• Cleaner Home: Fewer indoor accidents and a calmer household overall.

Portal Pros installs dog doors in virtually any location in your home, including:

• Interior and exterior doors (wood, metal, fiberglass)
• Exterior walls (vinyl siding, wood shake, cement board, brick, concrete, stucco)
• Sliding glass patio doors
• French doors (multi-lite or individual glass panes)
• Screen doors (sliding and swinging)
• Storm doors
• Windows (sash and side-sliding)
• Kennels and kennel runs
• Custom locations

Yes. Professional dog door installation is designed to maintain your home's security. Portal Pros uses weather-resistant and lockable pet doors that provide pet access while keeping your home safe. Many models include industrial-grade security panels and locking mechanisms. It's also important to note that a pet door is an exit — families with pools or young children should consider additional safety measures such as pool fences, door locks, or alarms.

Yes. Portal Pros carries American-made pet doors, sourced, manufactured, and assembled in the USA from start to finish.

When installed correctly by a professional, dog doors are sealed tightly to prevent drafts, air leaks, and water intrusion. Portal Pros installers pay close attention to critical details like proper caulking, ensuring the frame is sealed but not over-compressed, and correctly orienting wall-mounted frames so moisture drains outward. Many of the dog doors Portal Pros carries also feature insulated dual-pane glass options and magnetic seals for maximum energy efficiency.

Yes. Every Portal Pros installation is backed by a craftsmanship guarantee — if there is ever an issue related to the quality of the installation, the team will make it right. All installers are fully licensed, bonded, and/or insured. Additionally, all Security Boss pet doors come with a limited lifetime warranty directly from the manufacturer.

Absolutely. A portion of every Portal Pros sale goes directly to supporting no-kill animal shelters across the United States. Their mission goes beyond installing pet doors — it's about opening doors to a better life for animals in need.

An in-glass dog door installation involves replacing your existing glass panel with a custom-fabricated, tempered glass unit that has the pet door built directly into it. This gives your home a seamless, factory-finished look — no bulky add-ons or wall cuts required. The glass is custom ordered to fit your exact door or panel, so the result looks like it came that way from the manufacturer.

Portal Pros can install pet doors in glass panels from ¼" to 1½" thick, including:

• Sliding glass patio doors
• Fixed glass panels
• French door glass panes
• Single-pane and dual-pane insulated glass
• Low-E coated glass (compatibility maintained)

No — in fact, Portal Pros offers single and dual-pane insulated glass options with tight seals that maintain your home's energy efficiency. The in-glass dog doors are energy-smart, keeping drafts out while giving your pet the freedom they need. Low-E glass compatibility is also maintained with their custom glass fabrication process.

The process is straightforward:

1. Measure and size your pet and the glass panel
2. Order the custom glass with the pet door built in
3. A professional installer swaps out the original glass unit
4. Final seal and test to ensure smooth, draft-free operation

Most customers note the result looks factory-made with a clean, professional finish.

In-glass dog door installation is not a standard DIY project. It requires custom glass fabrication and specialized installation skills beyond the scope of a typical home project. Portal Pros strongly recommends professional installation to ensure a proper seal, correct glass fit, and long-lasting results.

Portal Pros carries a wide selection of in-glass pet doors by Security Boss, including:

• MaxSeal PRO In-Glass Dog Door (starting from $241.99)
• MaxSeal In-Glass Dog Door (starting from $240.89)
• SB Standard In-Glass Pet Door (starting from $202.40)
• PetSafe Electronic Dual-Pane Lockable Patio Pet Door (starting from $643.49)
• MaxSeal Insulated Locking Patio Pet Door Insert (starting from $819.49)
• Giant Breed Lockable Patio Pet Door (starting from $615.99)
• Elite Super Selective Sliding Glass Patio Pet Door Insert (starting from $549.99)
• Raccoon-Proof Sash Window Pet Doors (single and dual-pane)

Yes. Many of the in-glass pet doors Portal Pros carries include locking mechanisms, industrial security panels, and in some cases electronic smart-lock access. This allows you to restrict pet access when needed while keeping your home secure.

A wall mount dog door installation involves cutting an opening directly through an exterior wall and installing a pet door with a tunnel that spans the full wall thickness. This is ideal when there is no suitable door nearby or when a homeowner prefers not to modify an existing door.

Portal Pros installs wall mount dog doors through a wide range of wall types:

• Vinyl siding
• Wood shake
• Cement board
• Brick
• Concrete
• Stucco

Note: Brick, concrete, and stucco walls require a custom quote due to the added complexity of the installation.

Portal Pros carries wall mount pet doors that accommodate walls from 2" to 10" (and in some cases up to 16") deep, covering the full range of standard residential and commercial wall thicknesses.

Portal Pros carries several top-rated wall mount pet doors by Security Boss:

• MaxSeal Wall Mount Pet Door (from $248.72) — highly rated with 210+ reviews
• MaxSeal PRO Wall Mount Pet Door (from $281.59)
• SB72 Chew Proof Wall Mount Pet Door (from $391.59)
• SB Standard Wall Mount Pet Door (from $219.99)
• Custom MaxSeal Wall Mount Pet Door (from $299.19)
• Custom MaxSeal PRO Wall Mount Pet Door (from $372.89)

Yes. The SB72 Chew Proof Wall Mount Pet Door by Security Boss is specifically designed for dogs that chew or scratch at their door. It features a reinforced frame and flap system built to withstand aggressive chewers.

Wall mount installation is one of the more complex pet door jobs. Portal Pros installers pay close attention to critical details — including proper framing of the tunnel, correct caulking to prevent air and water leaks, and tipping the frame so moisture drains outward rather than pooling inside your wall. These nuances can lead to serious moisture and structural issues if overlooked. All installers are licensed, bonded, and/or insured.

Yes. Installation pricing is based on typical conditions. If the installer encounters hidden obstacles — such as electrical wiring, plumbing, ductwork, unexpected framing, masonry, tile, metal lath, or insulation issues — they will explain the situation and confirm any pricing adjustment before proceeding. There are never surprise charges after the work is done.

A door mount dog door installation involves cutting an opening in an existing interior or exterior door and installing a pet door directly into the door panel. This is one of the most common types of dog door installation and works with wood, metal, and fiberglass doors.

Portal Pros installs pet doors in both interior and exterior doors made of wood, metal, and fiberglass. Installation pricing differs between interior doors (starting at $264.97) and exterior doors (starting at $373.77) due to the additional work involved with exterior-grade materials and weatherproofing requirements.

Most door mount dog door installations are completed in less than two hours. More complex custom installations may take longer, but all jobs are typically completed in a single visit.

Professional installation ensures the opening is cut correctly, sealed properly, and that your door isn't damaged in the process. DIY installations often result in gaps, drafts, air leaks, or security vulnerabilities. Portal Pros technicians specialize exclusively in pet door installation — it's all they do — and every job is backed by a craftsmanship guarantee.

A patio dog door insert is a panel that slides into your existing sliding glass door track alongside the existing door, filling the gap and including a built-in pet door flap. These can be installed temporarily (without permanent modifications) or permanently. They are an excellent option for renters or anyone who doesn't want to cut into their existing glass or walls.

Portal Pros patio pet door inserts are sized and sourced to fit most standard sliding glass patio doors. Both single and dual-pane options are available, with manual or electronic operation. A Portal Pros expert can help you find the right fit for your specific door model.

Yes. Portal Pros offers insulated dual-pane patio inserts with draft-resistant seals. Customers have specifically noted the insulation difference immediately after installation, with no drafts and solid locking mechanisms maintaining home comfort.

Yes. Portal Pros carries the Giant Breed Lockable Patio Pet Door, starting from $615.99, specifically designed to accommodate large and giant breed dogs comfortably.

Yes. The PetSafe Electronic Dual-Pane Lockable Patio Pet Door by Security Boss (starting from $643.49) offers electronic locking and selective pet access, allowing only your pet to use the door while keeping other animals out.

Yes. Portal Pros specializes in French door dog door installation, including both multi-lite (small pane) French doors and individual full-glass French door panels. This is one of the more complex installation types due to the glass panel configurations involved, and professional installation is strongly recommended.

For French doors with individual glass panels, the process is similar to an in-glass installation — the existing glass pane is replaced with a custom-fabricated piece that has the pet door built into it. For multi-lite French doors, the installation approach varies based on the specific door configuration. Portal Pros will assess your door during the quote process and recommend the best approach.

French door installation (multi-lite or individual glass panes) starts at $863.68 for the installation service, reflecting the added complexity compared to standard door or wall installations. Pet doors are sold separately.

Yes. Portal Pros carries custom MaxSeal French door dog door options by Security Boss to accommodate non-standard French door configurations. Contact Portal Pros for a custom quote.

Yes. Portal Pros installs pet doors in both sliding and swinging screen doors. Screen door installation is one of the more affordable installation options, with professional installation starting at $289.79.

Portal Pros handles screen dog door installation in sliding screen doors and swinging screen doors. If you have a screen enclosure or patio screen, contact Portal Pros directly to discuss your specific setup.

Yes. Portal Pros installs pet doors in storm doors of all brands and sizes. Storm doors can present some unique challenges due to their glass and aluminum construction, so professional installation is recommended to ensure a clean, sealed result.

When installed professionally by a Portal Pros technician, the weatherproofing of your storm door is maintained. All cuts are properly sealed and caulked to prevent air and water infiltration. The installer will assess your specific storm door before proceeding.

Portal Pros carries pet doors specifically designed for storm doors in their collection. Visit theportalpros.com/collections/pet-doors-for-storm-doors to browse options, or call 855-DOG-DOOR for a personalized recommendation.

Yes. Portal Pros installs pet doors in windows, including sash (up/down sliding) windows and side-sliding windows. Window pet door inserts are a great solution when walls and doors aren't practical options, such as in condos, apartments, or rooms with specific layout constraints.

Portal Pros carries several window pet door options:

• SB Standard Sash Lockable Window Insert (from $263.99)
• MaxSeal Sash Lockable Window Insert (from $590.69)
• SB Standard Side Sliding Window Pet Door (from $285.99)
• Raccoon Proof Sash Window Pet Door — Single Pane Glass
• Raccoon Proof Sash Window Pet Door — Insulated Dual Pane Glass

A raccoon-proof pet door uses an electronic selective-entry mechanism that only opens for your pet wearing a compatible collar sensor, preventing raccoons, stray cats, and other wildlife from entering your home through the pet door. These are highly recommended in areas where wildlife intrusion is a concern.

Window sash inserts can be relatively quick to install. One Portal Pros customer noted their window pet door installation took about 10 minutes. However, for insulated dual-pane windows or lockable electronic options, professional installation ensures a proper fit and seal.

To size a dog door correctly, you'll need two key measurements from your pet:

• Height: Measure from the floor to the top of your dog's shoulders (withers). Add 1–2 inches above this for comfortable clearance.
• Width: Measure the widest part of your dog's body (chest or hips). Add at least 2 inches for comfortable passage.

Portal Pros carries dog doors sized from XS through XXL to accommodate all breeds. If you have multiple dogs, size for the largest one. If you have a puppy, size for their anticipated adult size.

Portal Pros carries extra-large and giant-breed specific dog doors, including the Giant Breed Lockable Patio Pet Door. For large breeds, ensure the flap opening is wide and tall enough that your dog doesn't need to crouch or turn sideways to pass through. Contact Portal Pros for sizing guidance for breeds like Great Danes, Mastiffs, Saint Bernards, or Newfoundlands.

Most Security Boss dog doors carried by Portal Pros are available in multiple color options including White, Beige, Brown, Silver, and Dark Bronze, allowing you to match or complement your home's existing trim and decor.

A manual flap dog door is a flexible panel your pet pushes through, which swings closed behind them. An electronic dog door uses a sensor (typically a collar tag) to automatically unlock and open only when your pet approaches, then closes and locks behind them. Electronic doors are ideal for keeping out wildlife, stray animals, or for selective pet access.

Over time, pet door flaps can wear out, crack, or lose their seal. Portal Pros carries replacement dog door flaps so you can restore your existing pet door without replacing the entire unit. Visit theportalpros.com/collections/replacement-dog-door-flaps to find the right replacement flap for your model.

Yes. Portal Pros carries custom MaxSeal and MaxSeal PRO dog doors in both wall mount and door mount configurations, as well as a dedicated custom pet door collection at theportalpros.com/collections/custom-pet-doors-for-doors-and-walls.

Most dogs take to their new pet door quickly. A common approach is to start with the flap propped open so your dog can walk through freely without resistance, then gradually lower the flap as they build confidence. Using treats as motivation on the other side of the door is highly effective. Many Portal Pros customers report their pets started using the door within hours of installation.
