“I have to tell you how pleased I am with my new patio/dog door. It's EXACTLY what I wanted. The two men you sent to install the door did such a fantastic job! They both were so nice and accommodating and a pleasure to have had them here.
They worked very hard to make sure everything fit perfectly, and left everything spotless! I'm very impressed with Sierra Glass. How wonderful it has been to have found a reliable, competent company. I could not be more pleased with the service or the doors.”

Why choose Security Boss MaxSeal pet doors?
Sierra Glass carries and installs Security Boss pet doors for 1 reason-they’re the best. In business for over 40 years, their goal has always been to design and manufacture dog doors of the highest quality so they focused on 3 areas.
- Best sealing pet door
- Best insulation design
- Unequaled security
Best sealing door means no drafts
The secret is their extra strong alnico magnets positioned in just the right places along the flap’s perimeter to ensure a solid seal while allowing your pet to easily go through it.
A special brush pile material is located between the magnets and the weather stripping fills the area to prevent any drafts or leakage. That's important when you live in the Pacific Northwest where we're famous for our wind and rain.
Dual flap offers better insulation
The dual flap in MaxSeal pet doors produces an air space between the 2 individual flaps to deliver the ultimate in insulation. The insulating effect is better than other rigid doors (regardless of their design or material) because cold is more easily transferred through a solid material.
Locking panel for better security
The slide-in locking security panel is constructed of several layers that combine to form a rigid, impact resistant barrier that insulates against extreme cold outside. Unlike locking covers on other pet doors that can be easily broken, the patented design on these panels are impact resistant and can withstand more force. When the panel is slid into place, you’ll feel its permanence, like you've just closed a heavy door.
Sliding screen pet door is perfect companion to your glass slider
If your slider has a screen door, you need the sliding screen pet door to go with it. It’s perfect because the bugs stay outside where they belong while letting cool air inside.
With a pet door on both your slider and screen door, you’ve got all your bases covered and your pet will always have access to your yard.
Installation to fit your schedule
Getting your new doggie door is easy as you don’t need to be home when we do the installation though we will need access to the inside of your home. Of course, if you want to be there, we’ll work with you to arrange a time that fits your schedule.
The MaxSeal In-the-glass pet door should only be installed by professional glaziers who have experience installing these doors and is not designed for homeowners, handyman or building contractors to install.
In-the-glass pet door is our best seller
Our most popular model is the MaxSeal in-the-glass pet door because it can be installed in sliding glass doors and French doors.
It has a low profile so the door can be operated without any problems and its rugged construction means it’ll last even when there’s multiple or large dogs using it.
