How Can I Tell if My Existing Patio Doors Need to Be Replaced?

If your patio doors are difficult to open, show signs of warping or damage, or allow drafts and moisture to seep inside, it may be time to consider a replacement. Sliding patio doors from One Window At A Time are an excellent upgrade. We work with top manufacturers like Simonton, Andersen, and Milgard to provide durable, high-performance sliding glass doors that not only improve functionality but also enhance aesthetic appeal.

During your no-cost consultation, we’ll explain how our doors are:

Incredibly Durable

Our sliding patio doors are made from high-performance vinyl that resists rot, fading, and deterioration over time. This durable material ensures your patio doors look and perform beautifully, even in Colorado’s challenging climate.

Highly Energy Efficient

Vinyl is a natural insulator, making our sliding glass doors an energy-efficient choice. These doors help reduce heat transfer, potentially lowering your energy costs while keeping your home comfortable year-round.

Installed by Experienced Professionals

At One Window At A Time, we believe in accountability and personalized service. You’ll have direct communication with our owner throughout the project, and we’ll keep you informed every step of the way. Our team won’t rest until you’re 100% satisfied with your new sliding patio doors.

“I am so happy with my new windows and patio door from One Window at a Time. The whole process was so easy. The owner came out to give me the bid. He was so nice and explained everything so well. Installation was amazing. They showed up on time and I couldn’t believe how fast they work and the installation went so well and cleaned up beautifully. The owner was there at the start and stayed for awhile to help then l came back at the end to see that all was done incredibly. All the great reviews you read here are true. I wouldn’t go anywhere else to buy windows. Love that this is a local company and not a big chain!”

“Everyone at One WIndow At A Time is fantastic! We replaced 11 windows on our home, along with a sliding glass door. They were extremely knowledgeable about the product, other products on the market, and the installation process. They were transparent with pricing and timeline for the project. Their communication and willingness to answer questions or address concerns exceeded our expectations. The installers were professional and we are so pleased with the craftsmanship. They took the time to seal everything up inside and out, and even took the weather into consideration during the installation process. Everything looks really clean, secure, and smooth. We love the windows, themselves, too. They can slide open from either direction and they easily pop out for convenient access for cleaning. We will definitely be calling One Window At A Time again when we are ready to replace the other windows on our home.”
