Give your pet the freedom they deserve without sacrificing the look or function of your home. Portal Pros offers three professional glass dog door installation methods — and we'll help you choose the right one for your specific door and lifestyle.
Full Door Replacement with Built-In Pet Door We replace your existing glass door entirely with a brand new door that has the pet door built in from the factory. Choose from clear glass, glass with partitions, or glass with integrated mini blinds for privacy. Your existing door hardware is reused, keeping the project clean and cost-effective.
Custom Notched Glass Replacement We remove your existing glass panel and replace it with a custom-fabricated tempered glass piece that has the pet door notched directly into it. You keep the full glass look — maximum light, unobstructed view — with a seamless, factory-finished result that looks like it was always there.
Individual Pane Replacement (True French Doors) If you have a true French door with individual glass panes, we replace a single pane with a custom-fabricated piece that has the pet door built in. No full door replacement needed — just a precise, clean swap of the specific pane.

What Is a Glass Dog Door Installation?
A glass dog door installation — also called an in-glass dog door or through-glass pet door — is a professional installation method that integrates a pet door directly into your existing glass door system. Unlike wall mount or door mount installations, there is no cutting through walls, no modifying door frames, and no bulky add-on panels sitting in your track.
Depending on your door type, Portal Pros will recommend one of three approaches: a full door replacement with a factory-built pet door, a custom notched glass panel that preserves your full view, or a single pane swap for true French doors with individual glass panes. Every method results in a clean, professional finish that looks completely intentional — because it is.
What Types of Glass Doors Can Have a Dog Door Installed?
Portal Pros installs glass dog doors into panels from ¼" to 1½" thick, including:
- Sliding glass patio doors — full door replacement or custom notched glass, depending on your preference
- Fixed glass panels — custom notched glass replacement for a seamless look
- True French doors with individual panes — single pane replacement, no full door swap needed
- Multi-lite French doors — custom approach based on your specific configuration
- Single-pane glass — standard residential glass panels
- Dual-pane insulated glass (IGU) — energy efficiency fully maintained with custom fabrication
- Low-E coated glass — Low-E compatibility preserved throughout the process
Not sure what type of glass you have? Send us a photo and we'll identify it and recommend the right installation method.
Which Glass Dog Door Installation Method Is Right for You?
Every home is different. Here's how to think about which approach fits your situation:
Choose full door replacement if: You want the option of partitions, mini blinds, or a specific glass style. Your existing door is older and due for an upgrade anyway. You want the pet door integrated at the factory level for the cleanest possible result. Your existing hardware is in good condition and can be reused.
Choose custom notched glass replacement if: You love your current door and want to keep it exactly as-is. Maximum light and an unobstructed view are important to you. You want the most seamless possible appearance — a custom notched glass panel is virtually indistinguishable from a factory installation.
Choose individual pane replacement if: You have a true French door with separate individual glass panes. You want the least invasive option — only the specific pane housing the pet door is replaced, everything else stays exactly as it is.
Still not sure? Call 855-DOG-DOOR or send us a photo of your door and we'll tell you exactly which option we'd recommend for your setup.
Why Choose In-Glass Dog Door Installation?
In-glass installation is the gold standard for pet door placement for homeowners who want zero compromise on aesthetics.
Seamless appearance. Whether you go with a full door replacement, custom notched glass, or a single pane swap — the finished result looks completely intentional. No bulky frames, no patio inserts taking up track space, no afterthought appearance.
Superior insulation. Custom dual-pane glass options maintain your home's thermal envelope. Tight factory seals mean no drafts, no air leaks, and no energy loss.
Maximum security. Every in-glass dog door Portal Pros installs includes an industrial-grade security panel that locks from the inside, giving you full control over when your pet can and cannot use the door.
No wall damage. Unlike wall mount installations, glass installs require no cutting through drywall, insulation, or siding. Your home's structure stays completely intact.
Privacy options. With a full door replacement, you can choose integrated mini blinds or partitioned glass — giving you privacy control alongside pet access that no other installation method offers.
Works for all breeds. Portal Pros carries in-glass dog doors sized from XS through XXL — including giant breed options for Great Danes, Mastiffs, Saint Bernards, and Newfoundlands.
How the Glass Dog Door Installation Process Works
Step 1 — Measure & Quote Contact Portal Pros with your pet's shoulder height and width, and photos of the glass door or panel you'd like the dog door installed into along with either the door or glass dimensions. We'll identify your door type, recommend the right installation method, and provide a same-day quote.
Step 2 — Fabrication Depending on the method chosen, your replacement glass panel or full door unit is custom fabricated to the exact specifications of your existing opening — with the pet door built directly in. Single or dual-pane, Low-E compatible, sized precisely for your pet. Once you order we send our installers out to verify all dimensions precisely.
Step 3 — Professional Installation An authorized and insured Portal Pros technician arrives to install the pet door and glass or full door. For full door replacements, your existing hardware is transferred to the new door. For notched glass or pane replacements, the existing frame stays in place — only the glass is swapped. Everything is sealed, aligned, and tested.
Step 4 — Final Test & Walkthrough Your installer tests the door operation, confirms the seal, and walks you through the locking mechanism. Most customers describe the finished result as completely indistinguishable from a factory installation.

How Much Does Glass Dog Door Installation Cost?
Glass dog door installation pricing depends on the installation method, the type and size of your glass panel, the pet door size needed, and the specific product selected. Because every in-glass installation involves custom fabrication — whether that's a full door, a notched glass panel, or a single pane — Portal Pros provides personalized quotes rather than a flat rate.
Factors that affect pricing:
- Installation method (full door replacement vs. notched glass vs. pane replacement)
- Single-pane vs. dual-pane glass
- Glass panel dimensions
- Pet door size (XS through XXL)
- Product selection (standard vs. PRO vs. electronic)
- Optional features such as mini blinds or partitioned glass

Glass Dog Door Installation — Frequently Asked Questions
What's the difference between a full door replacement and a notched glass replacement? A full door replacement swaps your entire glass door with a new factory unit that has the pet door built in — with options for clear glass, partitions, or mini blinds. A notched glass replacement keeps your existing door frame and hardware exactly as-is, replacing only the glass panel with a custom piece that has the pet door built in. The notched glass method preserves your maximum light and view with no visible change to the door itself.
Can a dog door be installed in any sliding glass door? In most cases, yes. Portal Pros can install glass dog doors in the vast majority of standard residential sliding glass patio doors using either the full door replacement or custom notched glass method. Our installers confirm compatibility during the quoting process.
Can a dog door be installed in a French door? Yes. For true French doors with individual glass panes, Portal Pros replaces a single pane with a custom-fabricated piece containing the pet door. For multi-lite French doors, the approach varies based on your specific configuration. Send us a photo and we'll assess your door directly.
Will replacing the glass affect my home's insulation? No. Portal Pros fabricates all replacement glass in single or dual-pane configurations, including Low-E glass options. Your home's insulation and energy efficiency are fully maintained regardless of which installation method you choose.
Can I get mini blinds in my replacement glass door? Yes — but only with the full door replacement option. If you choose a custom notched glass panel or a single pane replacement, the glass itself does not include blinds. Full door replacement units are available with integrated mini blinds, clear glass, or partitioned glass depending on your preference.
How long does glass dog door installation take? Most in-glass installations are completed in a single visit. The glass or door unit is custom fabricated in advance, so your installer arrives ready to complete the swap. On-site installation typically takes one to three hours depending on the method.
Can I install an in-glass dog door myself? In-glass installation is not a DIY project. It requires custom glass fabrication, proper glazing techniques, and precise sealing to prevent air and water infiltration. Improper installation can result in cracked glass, failed seals, or voided warranties. Professional installation by a licensed Portal Pros technician is always recommended.
What if my glass panel is an unusual size? Not a problem. Every replacement glass panel Portal Pros orders is custom fabricated to your exact dimensions. There is no standard size requirement — we work with what you have.
Is the pet door lockable? Yes. Every in-glass dog door Portal Pros carries includes a locking security panel. Electronic options with collar-sensor or microchip-based selective entry are also available for maximum security.
What size dog door do I need? Measure your dog's shoulder height from the floor to the top of their shoulders and add 1–2 inches. Measure their widest point — chest or hips — and add at least 2 inches. Portal Pros carries sizes from XS through XXL. If you're between sizes, always size up. Contact us if you need help sizing for a giant breed.
Do you install glass dog doors nationwide? Yes. Portal Pros operates a nationwide network of licensed, bonded, and insured installers. A professional in your area will contact you within 24–48 hours of placing an order.

Let customers speak for us
I was beyond impressed with the level of customer service from Bryan. I had attempted contact with another company seeking assistance on where to place a dog door that made the most sense- but I was matched with a bot thatwas clearly giving me template answers. That was not so with Portal Pros. Bryan was incredibly helpful and attentive with a customized solution. Installation was excellent, and the install team was professional and great with our dogs.
I love my door! They were most affordable out of everyone I quoted and the door is high quality. Would recommend.
Bryan and his team of installers were very professional, responsive and reliable. Bryan followed up on my questions and addressed efficiently several points that I raised.
I was worried about how it would look when finished but I couldn’t be happier. David took his time and custom fit the portal and trim perfectly. Both inside and out it looks great and Penny LOVES it!
Yes and yes. Highly recommend these folks and this product. We’ve had our doggy door (a pet door) since our home was built in 2011, (yes it lasted that long, a testament to the quality) and after years of use, the flaps needed replacing. We spent months hunting for the right parts, and my husband finally found the original manufacturer—turns out Brian, the owner and designer door of Portal Pros Austin, was still directly connected to that company!
Brian, along with Jason and Chris, came out promptly and tackled the job with real joy, a genuine customer-focused approach, and clear pride in their work and the products. They efficiently replaced the flaps on our doggy door.
What truly stood out was how they went above and beyond: they replaced the inside carrier/tunnel which was eaten by our 2yr old golden doodle a year ago , so they replaced that too. Our pups now zip in and out happily, no more paw slipping.
The whole team was polite, professional, clean, and obviously passionate about pet doors. If you’re in the Austin/Georgetown area and need expert installation, repair, or replacement for any type of pet door (glass, walls, patio doors, etc.), Portal Pros Austin is the way to go. Brian, Jason, and Chris delivered top-notch service and made our furry family member so much happier.
Huge thanks to the team—you’re fantastic! Highly recommend and would use them again in a heartbeat.
Excellent product; only reason I didn’t give five stars is that scheduling the installation took a little coordination. Otherwise flawless.
This thing is built like a tank. It handled our windy balcony without any movement and the seal is impressive. Highly recommend for insulated patio doors
Product quality looks good and they had an installer in my area
We bought the MaxSeal Pro for our condo’s sliders. Technician explained everything clearly, happy with product and service
We are very happy with the new door and our pups started using it immediately. Kudos to the installers for their timeliness and prompt service. A+
Perfect fit for a custom glass panel. Our dogs learned to use it in a few hours. The energy efficiency claims seem legit.
I am so thankful for you and your company for the excellent job of installing our doggie door in our glass door. It’s perfect.
From start to finish I appreciate your hands on process. You kept us informed every step. Ours dogs love it. Thanks again.
Needed a connection from the house to the new catio. We ordered this one and it was perfect. Installation was a 10 minute project. I would recommend portal pros to anyone needing ingress , egress for their pets.
Great guys came out and measured and had everything installed in 2 weeks - would use again
Installed this in our sliding patio and instantly noticed the insulation difference. No drafts and the locking mechanism feels solid. Our corgi took to it within a day. The pet door guidance was spot on.
