We have 44,000 square feet of manufacturing space and numerous highly skilled craftsmen, which gives us the capacity to build your custom doors just how you want them. Portella’s doors have top of the line design and durability, and are sure to add a high value to your property. With our experience working in and around the Austin area since 1999, we have the mastery and artistry to offer beautifully crafted custom doors for your business or home.

Austin Custom Doors Details

Portella offers five different metal glass doors including: French doors, sliding doors, double doors, bi-fold doors, and a minimalistic single door. Our in-house manufacturing space gives us a lot more control over the customization process. We’re able to either create something entirely new or customize our pre-existing door styles, depending on what your project calls for.

We strive to create custom doors that excel both in their appearance and utility. To that end, Portella is the only door manufacturer of thermally broken doors to include a thermally-bonded zinc galvanizing corrosion resistant coating on many of our custom doors. This allows us to produce doors that are not only aesthetically classic and clean, but also weather resistant and energy efficient.
