Custom Doors in Houston

Portella offers an extensive range of glass doors made for commercial and residential purposes. However, we understand that sometimes you need something a little more specific. Houses and businesses have different personalities, different architectural needs, and particular specifications, and not every product will fit your exact requirements. That’s why Portella strives to offer custom doors, designed and manufactured to your exact specifications.

We believe in customization and helping people realize their architectural visions, which is why most of Portella’s products can be customized to fit your project. You want your home or business to look a certain way, and we want to help you with that. Working in and around the Houston area for over 20 years, Portella is proud to continue offering beautifully crafted custom doors for businesses and homebuilders.

Houston Custom Doors Details

Portella offers a range of five different metal glass doors including: French doors, sliding doors, double doors, bi-fold doors, and a minimalistic single door. No matter what it is your project calls for, we can either customize our pre-existing style of doors or create something entirely new. Since we have an in-house manufacturing space, we have a lot more control over the products we create. 

At Portella, we seek to blend aesthetics and function in every product we make. All of our custom doors and designs go through rigorous testing to ensure that they live up to our standards. 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 helps us produce doors that are weather resistant and energy efficient, all while preserving the classic look and clean sightlines of Portella doors.

We currently manufacture four lines of custom metal doors:

  • Thermally BrokenThermal steel doors deliver robust durability and exceed all current energy efficiency requirements. We are the only custom steel door manufacturer to include a thermally-bonded zinc galvanizing corrosion resistant coating for doors that can withstand the harshest weather conditions.
