Most Popular Option
The fastest way to add a pet door to your sliding glass door. No glass cutting, no replacement panels, and installation in under one hour. The insert slides into your existing track.
A panel insert is a tall, narrow unit that fits into the track of your existing sliding glass door. The lower section contains the pet door flap opening, while the upper section is filled with tempered glass or aluminum. Your existing glass panel stays in place -- the insert simply occupies the space beside it.
Panel inserts are the most popular pet door solution for DMV homeowners with sliding glass patio doors. No construction mess, no lead time for glass fabrication, and fully reversible if you move or no longer need the pet door.
Premium Option
For the cleanest, most permanent result, we fabricate a new tempered glass panel with the pet door opening pre-cut before tempering. The panel replaces your existing glass for a seamless integrated appearance.
Tempered glass cannot be cut or drilled after manufacturing -- it will shatter. That is why we fabricate a brand-new panel with the pet door cutout already made at the factory before the tempering process. The result is a clean, precise opening with polished edges that accepts the pet door frame perfectly.
Glass fabrication takes 5 to 10 business days. We measure your door, order the panel, and schedule installation for a single visit once the glass arrives. The old panel is removed and the new one installed in 2 to 3 hours.
Installation Options
From quick panel inserts to custom tempered glass fabrication to smart electronic access, we offer every pet door solution for glass doors and windows.

Smart Access
Electronic pet doors use microchip readers and RFID collar sensors to grant access only to your authorized pets. Strays, raccoons, and neighborhood animals stay locked out.
The electronic pet door contains a sensor that reads your pet's implanted microchip or a small RFID tag on their collar. When an authorized pet approaches, the door unlocks the flap. After entry, the door locks again automatically. Unauthorized animals get no response from the door -- it stays sealed.
Reads the ISO 15-digit microchip already implanted by your veterinarian. No collar tag needed. Works with all standard pet microchips used in the United States.
Small, lightweight tags that attach to your pet's collar. Useful when microchip reading is unreliable or your pet is not microchipped. Replacement tags are inexpensive.
Set time-based access for each pet individually. Keep the indoor cat locked in after dark. Allow the dog out during daytime hours only. Control via the door panel or smartphone app.
Program up to 32 individual pets on a single electronic door. Each pet gets their own access profile and schedule. Add or remove pets at any time through the control panel.

Size Guide
We measure your pet during the consultation to specify the exact door size. Here are the standard size categories and the breeds they accommodate.
Flap opening approximately 6 x 6 inches to 7 x 11 inches. Designed for cats and small dogs up to about 15 pounds -- breeds like Chihuahuas, Yorkshire Terriers, Dachshunds, and most domestic cats. The smallest pet doors minimize the opening size for better energy efficiency and security. Ideal for DMV cat owners who want outdoor access.
Flap opening approximately 8 x 12 inches to 10 x 15 inches. Fits medium dogs from 15 to 40 pounds -- breeds like Beagles, Cocker Spaniels, French Bulldogs, Corgis, and Cavalier King Charles Spaniels. The most popular size range for DMV homeowners with family dogs.
Flap opening approximately 10 x 16 inches to 12 x 18 inches. Designed for large dogs from 40 to 80 pounds -- breeds like Labrador Retrievers, Golden Retrievers, German Shepherds, Standard Poodles, and Boxers. Requires a larger glass cutout and sturdier flap mechanism with reinforced hinges.
Flap opening approximately 14 x 20 inches or larger. Built for giant breeds over 80 pounds -- Great Danes, Saint Bernards, Mastiffs, Bernese Mountain Dogs, and large mixed breeds. Extra-large pet doors use reinforced flaps, heavy-duty hinges, and specialized frame construction to handle the size and weight.
Energy Performance
Many pet owners leave the sliding door cracked open for their pet, wasting energy year-round. A sealed pet door with dual insulated flaps is dramatically more efficient.
A sliding glass door cracked open 4 to 6 inches creates a continuous gap that allows conditioned air to escape and outdoor air to enter. Your HVAC system runs constantly trying to compensate. In the DMV climate with hot summers and cold winters, this costs hundreds of dollars per year in wasted energy.
Benefits
Your dog or cat can go outside and come back in on their own schedule. No more waiting by the door, scratching at glass, or waking you up at 5 AM for a morning bathroom trip. Pets with yard access to exercise, explore, and relieve themselves on demand are healthier and better behaved.
Pets that scratch at glass doors to go out cause permanent damage to the glass surface over time. Scratched glass is expensive to replace. A pet door eliminates the scratching behavior by giving your pet a dedicated passage, preserving your glass doors, frames, and weatherstripping.
A pet door is far more energy-efficient than leaving a sliding glass door cracked open. Modern pet door flaps with dual-layer insulation and magnetic seals reduce air infiltration by 80 to 90 percent compared to an open gap. Your HVAC system works less with a sealed pet door than a propped-open slider.
Electronic pet doors with microchip or RFID access prevent unauthorized animals and potential intruders from entering through the pet door opening. Locking panels provide manual security when the pet door is not in use. You maintain full control over who enters your home.
Program electronic pet doors for multiple pets with individual access schedules. Keep the indoor cat inside while the dog has yard access. Set daytime-only access for pets that should be indoors at night. Each pet gets customized freedom based on your household rules and safety requirements.
A professionally installed glass pet door looks clean and intentional rather than improvised. Custom glass panels with integrated pet door openings are virtually invisible from a distance. The installation maintains the aesthetic integrity of your home with no rough cuts or ill-fitting aftermarket panels.
Security & Access Control
Modern pet doors offer multiple layers of security to prevent unauthorized entry by wildlife, strays, and intruders while giving your pets the freedom they need.
Every pet door includes a slide-in or snap-on locking panel that completely blocks the pet door opening. Use the locking panel when you are away from home, during severe weather, or at night. The panel prevents unauthorized entry and provides an insulated seal when the door is not in use.
Electronic pet doors read the ISO-standard microchip implanted in your pet by the veterinarian. The door unlocks only when your pet approaches and locks immediately after entry. No collar tag required -- the microchip is permanent, cannot fall off, and cannot be lost. Program up to 32 pets on one door.
For pets without microchips or where microchip reading is unreliable, RFID collar tags provide reliable electronic access. The small tag attaches to your pet collar and communicates with the door sensor from several inches away. Replacement tags are inexpensive and readily available at pet supply stores.
Set time-based access rules for each pet. Keep the indoor cat locked in after dark. Allow the dog out only during morning and evening hours. Timer-based schedules give you control over each pet outdoor access without remembering to manually lock and unlock the pet door throughout the day.
DMV homeowners near wooded areas face raccoon, opossum, and fox intrusion through pet doors. Electronic pet doors eliminate wildlife entry by requiring an authorized microchip or RFID tag. The door stays locked to all animals except your registered pets, protecting your home from unwanted visitors.
Concerned about security? Small and medium pet doors are too small for human entry. Large pet doors can be secured with reinforced locking panels and electronic locks. Some electronic pet doors include alarm integration that alerts you when the door is opened without authorization.
How We Work
We measure your pet shoulder width and back height to determine the correct pet door size.
For custom glass panel installations, we order a new tempered glass panel with the pet door cutout pre-made before tempering.
We remove the existing glass panel (if replacing), install the new glass with integrated pet door opening, mount the pet door frame and flap assembly,
We demonstrate how the pet door operates and provide tips for training your pet to use it confidently. Most dogs learn within a day or two with treat encouragement. Cats may take slightly longer. We ensure the flap swings freely, the magnetic seal engages properly, and any electronic features are programmed for all your pets.
Compatible Glass Types
The most common installation location for pet doors across the DMV. Options include panel inserts that fit in the existing track (no glass changes needed) or a custom replacement glass panel with the pet door opening pre-cut. Both single-slider and double-slider configurations are supported.
Pet doors are installed in one panel of a French door pair. The glass is replaced with a new tempered panel that includes the pet door cutout. The pet door frame style and finish are selected to complement the French door hardware. Muntin patterns can be replicated on the replacement panel.
Hinged glass doors in metal or wood frames can receive pet door panels. The existing glass is removed and replaced with a new tempered panel that includes the pet door opening. This approach works for back doors, basement doors, and any single glass panel in a frame throughout your home.
For homes without suitable glass doors, pet doors can be installed in window glass panels. A lower sash or fixed window panel is replaced with a new panel that includes the pet door. Window pet doors work well for cats and small dogs where a door installation is not practical or available.
Double-pane and triple-pane insulated glass doors can receive pet door panels. We fabricate insulated glass units with the pet door cutout integrated into the manufacturing process. The replacement IGU matches your existing glass specifications for thermal performance.
Custom patio door panels with integrated pet doors replace a section of your existing patio door system. This option works for multi-panel patio doors, bi-fold door systems, and large-format sliding doors. The pet door panel matches your existing frame color, glass type, and hardware.
Care & Maintenance
Inspect the pet door flap monthly for tears, cracks, or warping. The flap takes daily abuse from your pet pushing through it. Replace damaged flaps promptly to maintain the weather seal and insulation. Most manufacturers sell replacement flaps that install in minutes without tools.
Clean the magnetic seal strips on the pet door flap and frame quarterly. Dirt, pet hair, and debris accumulate on the magnets and reduce seal effectiveness. Wipe the magnets with a damp cloth to restore full contact and sealing force. A weak seal allows drafts and insects to enter.
For electronic pet doors, replace batteries on the recommended schedule (typically every 6 to 12 months). Keep the microchip reader sensor clean. Test the locking mechanism monthly to ensure it engages and releases properly. Update firmware if your model supports app-based updates.
The weatherstripping around the pet door frame wears over time from daily use. Inspect weatherstripping annually and replace it when you see gaps, compression, or deterioration. Fresh weatherstripping maintains the energy efficiency and weather seal of your pet door installation.
