Pet Door Installation in Salt Lake County: Sizing, Placement, and Weatherproofing

I cannot tell you how many times I have been called to a house in Sandy or Draper to fix a pet door that the homeowner bought online, only to find out it is completely the wrong size for their dog. People usually just look at the weight rating on the box—"Up to 80 lbs!"—and assume it will work. But dogs are built differently. A heavy, compact Bulldog has a totally different profile than a tall, lanky Greyhound. If you get this wrong, you are setting your pet up for daily frustration, or worse, an injury when they try to squeeze through a hole that is just an inch too short.

The right way to measure your pet is to look at their shoulder height and the widest part of their body, which is usually the chest or hips. You want the top of the opening to be mounted at least two inches taller than their shoulders. If the dog has to duck down every single time they go out to the yard, they will eventually stop using it, or they'll develop back and hip issues over time. You also need to add practical clearance to the width so they don't scrape their sides when they are running through it at full speed chasing a squirrel.

If you have a multi-pet home, or if you just adopted a puppy that hasn't fully grown into its paws yet, the math gets a little trickier. I almost always recommend going up one size from what you think you need, as long as the framing of the door or wall allows for it. A slightly larger flap won't bother a smaller dog, but a flap that is too small makes the entire project completely useless. We take the time to get these measurements locked in before we ever pull out a saw, because once you cut a massive hole in your back door, there is no going back.

Most people immediately point to the backdoor in the kitchen and say, "Put it right there." But before we start cutting into what is likely a very expensive exterior door, I like to take a step back and look at how the family actually uses the house. Yes, the backdoor is the most common spot, but sometimes it is the worst possible choice. If that door opens directly into a high-traffic kitchen area, you are going to be tripping over your dog every time you try to carry groceries inside.

We need to balance yard access with your daily routine and, frankly, your home's security. Sometimes, putting the pet door into a side wall in the mudroom or the laundry area makes infinitely more sense. It keeps the muddy paw prints contained to a space with hard flooring, and it keeps the heavy pet traffic out of the main living areas. If we do go through a wall, we have to check the exterior approach. If the dog has to jump three feet down onto a concrete patio, we either need to build a small ramp or find a different spot.

We also have to think about the physical structure of the door itself. A lot of modern Salt Lake County homes have beautiful, multi-panel fiberglass or steel doors with glass inserts. You can't just slap a standard square frame into a deeply paneled door; it won't seal right, and it will look terrible. If the door isn't suitable, an in-wall installation is usually the cleaner, more secure option. It allows us to avoid compromising the structural integrity of your main entryways while still giving your pets the freedom they need. It takes a bit more planning, but the long-term usability is always better.

This is where cheap pet doors completely fail. In Salt Lake County, we have a brutal climate. We get blistering heat in August and sub-zero temperatures with howling canyon winds in January. If you install a basic, single-flap plastic pet door, you are essentially cutting a permanent, uninsulated hole in your house. I have seen homeowners tape cardboard over their pet doors in the winter because the draft is freezing their entire kitchen. Proper weatherproofing is absolutely not optional in our environment.

When we handle an installation, we look for dual-flap systems with magnetic closures that actually snap shut against the wind. The air pocket trapped between the two flaps acts as insulation, drastically reducing heat loss. But the flap itself is only half the battle. The seal around the frame is just as critical. If we are cutting through a wall, we have to deal with the siding, the house wrap, the insulation, and the interior drywall. We seal every single layer with premium exterior-grade silicone to ensure moisture never gets a chance to rot out your framing.

The finish quality is just as important to me as the weather seal. A pet door shouldn't look like a sloppy afterthought. When we do an in-wall install, we trim out the interior to match your existing baseboards and casing. We want the new opening to look completely integrated with the architecture of your home, not like someone just took a reciprocating saw to the drywall in a panic. Doing it right takes patience, the right sealants, and an eye for finish carpentry. It’s the only way to protect your home's energy efficiency and keep the space looking professional.

Every pet door installation is unique because every house, and every dog, is different. I can't give you a realistic quote over the phone without seeing what we are cutting into. We need to look at the material of your exterior door, check the stud spacing if we are going through a wall, and verify that there aren't any hidden plumbing pipes or electrical wires exactly where you want the new opening. That is why an on-site review is always the smartest first step.

We will measure your dog, check the exterior landing pad for safety, and walk you through the pros and cons of door versus wall placement. My goal is to make sure you get a setup that lasts for the life of your pet without ruining the look or the efficiency of your home. Sometimes that means talking you out of the cheapest option and pointing you toward a system that will actually survive a Utah winter.
