Three Ways to Add a Pet Door
Whatever your home needs, we have a clean, weather-tight solution — installed right the first time.
Built Into a New Entry Door
Replacing your door anyway? We build a pet door into a new ProVia entry door for the cleanest, most weather-tight result — factory-matched and made for Colorado weather.
Get My PriceInto Your Existing Door
Love your current door? We professionally cut and fit a quality pet door into it — fast, affordable, and sealed tight against drafts.
Get My PriceThrough an Exterior Wall
No good spot in a door? We run a pet door straight through your wall — siding, stucco, or brick — with an insulated tunnel and dual flaps so it can go almost anywhere.

More freedom for your pet — and less wear on your home.
Freedom for Your Pet
Your dog or cat comes and goes on their own schedule — fewer accidents, less scratching at the door, and no more 5 a.m. wake-ups.
Built for Colorado Weather
Energy-efficient dual-flap and insulated models seal tight against cold, heat, and wind — some stay flexible down to -40°F — protecting your comfort and your energy bills.
Keep Wildlife Out
Electronic and microchip options unlock only for your pet — keeping raccoons, strays, and neighborhood critters outside where they belong.
Easy on Your Home
No more clawed doors or muddy paw prints on the glass — just a clean, durable opening sized to your pet.
Find the Right Pet Door
From standard flaps to smart microchip doors — we'll match the right one to your pet and your climate.
Standard Flap
Durable, weather-resistant flaps for everyday access — great value for covered or interior spots.
Energy-Efficient Dual-Flap
Insulated, magnet-sealed flaps that hold their seal in Colorado wind and cold. Our most popular for exterior installs.
Electronic / Microchip
Reads your pet's microchip or collar key and unlocks just for them — maximum security against wildlife and strays.
Patio / Sliding-Glass Insert
A pet door built into a panel that drops into your sliding-glass-door track — no cutting, and easy to remove.
Sized Right for Your Pet
From cats and small dogs to large breeds over 100 lbs, we help you choose the right opening so your pet fits comfortably and the seal stays tight. Not sure what you need? Send a few photos and we'll recommend the perfect size and model.

What Colorado homeowners are saying.
I highly recommend the Colorado Door Store! Jason was great to work with, friendly, dependable, did a fantastic job on two large door and trim installs, and provided competitive pricing. Five stars all around!
Repeat customer. I met Jason over 10 years ago when he installed new doors at my home. His work is top notch. My home is older and not standard, and Jason was creative and put on a beautiful new door for me. I trust him completely.
Jason is the best! Seams are perfect inside and out. You can hardly tell he was in our house, his prep and cleanup were impeccable.
