Pet door questions, answered.

Choosing a door and cutting into your home can bring up a lot of questions. These answers are a practical place to start.

Choosing the right door

How do I choose the right pet door size?

Measure your pet at the widest point and from the floor to the shoulders. The opening should allow comfortable movement without forcing your pet to crouch or step unnecessarily high.

What if I have pets of different sizes?

Plan around the largest pet while keeping the step-over height comfortable for the smallest. Many smaller pets can use a larger opening, but age, mobility, and confidence should also be considered.

Should I size the door for a growing puppy?

Yes. Use the expected adult size and build of the dog when selecting the opening. Breed guidance can help, but a final recommendation should also consider the individual dog and the proposed location.

Can cats use the same door as dogs?

Often they can. The opening, step-over height, flap weight, and the cat’s comfort all matter. A shared door should work safely for every pet expected to use it.

What is the difference between a standard and premium pet door?

The standard multi-door is available in plastic or steel and uses a three-flap system. The premium double-door uses high-grade aluminum, two premium flaps, and a carpeted tunnel, with more height and width options for a custom fit.

Your home and installation

Can a pet door go through a wall or an existing door?

Both can be possible. The right approach depends on the material, framing, panel layout, available clearance, and the landing area on each side.

Can you install a pet door through brick?

Brick installations are possible in many homes, but they require extra planning for the masonry, wall structure, finished opening, and weather protection. The location should be assessed before a door is selected.

What about stucco or wood siding?

Stucco and wood-sided walls can both be candidates for a pet door. The wall assembly, framing, moisture barrier, utilities, and exterior finish need to be considered before work begins.

How do you check for wiring, plumbing, or other obstacles?

The proposed location should be evaluated before cutting. Wall construction and visible conditions help guide placement, and a different location may be recommended when an obstruction or uncertainty is found.

Do I need approval from an HOA or landlord?

Possibly. Renters should obtain the property owner’s permission, and homeowners should review any HOA rules that apply to exterior changes before scheduling an installation.

Pricing and the appointment

How much does pet door installation cost?

Cost depends on the door size and style, the home’s material, and the complexity of the opening. The online estimator provides a conceptual starting point, and final details should be confirmed before booking.

Why do brick and specialty walls cost more?

Dense or layered materials take more time, specialized tools, and additional finish work. The opening also needs to be planned carefully to protect the wall and produce clean interior and exterior edges.

How long does installation take?

Timing varies with the material, access, door type, and conditions found at the location. A straightforward installation may be completed in one visit, while complex work can require more planning.

What should I prepare before the appointment?

Clear furniture and personal items from both sides of the proposed location, provide safe access to the work area, and plan a comfortable place away from the work for pets and children.

What information helps with an estimate?

Pet measurements, the number of pets, and clear photos of both sides of the proposed location are a useful start. Include the wall or door material if you know it.

Living with a pet door

Are pet doors secure?

Security varies by product. Door construction, locking covers, placement, and opening size all matter, so security priorities should be discussed when choosing between standard and premium options.

Will a pet door let in heat, cold, or drafts?

Any opening can affect comfort, but fit, flap design, seals, and installation quality make a meaningful difference. Multi-flap premium doors are designed to provide greater separation from outdoor conditions.

How do I teach my pet to use the door?

Use short, positive practice sessions and let your pet move at a comfortable pace. Begin with the flap held open when possible, reward calm progress, and never force the pet through.
