Quality with a Personal Touch

Custom steel doors and windows that fit your space perfectly.

Portello wants to be your partner in creating the perfect Costa Mesa home or business. 

We help you create custom steel windows and doors in Costa Mesa that best suit the personality of your area. These steel windows and doors are durable and energy-efficient, but they are also customizable to your needs and desires.

Energy Efficient Custom Steel Windows and Doors

Increase the value of your home by saving money on your energy bills.

Dry summers and mild winters characterize Costa Mesa. Most people use energy-saving devices, and such generate a lot of heat. Thus, we use the latest technology to make our Costa Mesa steel windows and doors more energy efficient.

Costa Mesa — once a “coastal tableland” — has evolved from a humble Native American town used to graze cattle – to a world-class metropolis.

With its interesting arts, unique cuisine, and beautiful beaches, Costa Mesa is the loveliest vacation spot in California. Our steel doors and windows match the natural scenery.

We offer a variety of solutions, such as custom steel windows and doors with LowE glass or insulated glazing units (IGUs), which can reduce heat transfer by up to 80%. Our patented thermal break steel series help neutralize condensation and frost from the inside, with high-temperature resistance of up to 200°C.

We take pleasure in offering custom steel windows and doors that fulfill all of your requirements.

Steel Windows: Made with Pride, Built to Last

Portella is the only custom steel windows company that uses a zinc-bond galvanizing process. Our Costa Mesa steel windows and doors are also made entirely of 100% recyclable steel. We are both humbled and honored to be able to maintain the natural beauty of Costa Mesa by utilizing recycled materials.

Our custom steel windows are rust and corrosion-resistant; they are weatherproof. So you never have to worry about them peeling, fading, or chipping away. 

Steel Doors: Strong Protection

Steel is a superior material for doors and frames because it lasts longer and requires fewer repairs than other products. It’s much more durable. 

Steel doors aren’t just for commercial businesses anymore; they’re for residences too. And with all these benefits comes one more bonus: safety- not just from fire but sound reduction as well. Steel doors add security, preventing criminals from breaking into your home with sturdy metal blocking every entranceway. 

Our steel doors and windows can last a lifetime and then some. With Portella, you’ll never have to worry about replacing your door or window again!
