Frequently Asked Questions
About Patio Doors

Question list

Are your patio doors energy efficient?

Absolutely. Some window and door contractors in Charlotte will cut corners when it comes to patio doors. At Zen Windows, we are a sliding door contractor in Charlotte who understands that patio doors have 4X more glass than a window. That’s why we take extra care to make sure our doors are the most energy efficient.

Every patio door we offer comes with a technologically advanced, double-insulating Solar LowE glass system and foam filling in the frames. You get double-strength glass, a high-performance Low-E coating, stainless steel Intercept™ spacer system and argon gas. This is a technologically superior combination that provides excellent energy efficiency.

You also have the option to improve energy efficiency even more. We offer double- or triple-glass configurations and several Low-E coatings and spacer options.

Can I find a cheaper patio door than you offer?

Yes. But we know of no new door contractor in Charlotte that provides a better value on patio doors.

We understand that there is always someone willing to offer products for a lower price. Unfortunately, “rock-bottom” pricing usually comes with “rock-bottom” inferior products and sloppy “rock-bottom” installation. If that cheaper door comes at the cost of having to replace it again, it really isn’t a good value.

We’re different. We keep all the focus on quality, and cut out anything that needlessly adds to your costs. (Like armies of salespeople, overhyped marketing, and a fancy showroom.) All this allows us to offer top products at reasonable prices.

Do your patio doors come in a range of colors?

Patio Doors FAQ

Yes. We have 14 different exterior colors, 3 different colors of vinyl, and several wood grain interior options. We also have several premium handle options to match the styling on your home, such as oil-rubbed bronze, satin nickel, bright brass and antique brass. Our wide selection means you get the exact right patio door to match the styling of your home and your budget.

How long can I expect my patio door to last?

A lifetime. With our rock-solid Lifetime Warranty on both the product and the labor, you have ‘peace-of-mind.’ (It even covers glass breakage!) And the quality of these patio doors keeps them operating smoothly, decade after decade.

Who will be installing my door?

A well-trained, experienced lead installer. We also make sure all our lead installers are good communicators with no language barriers.

We don’t use “temporary labor” pools or inexperienced installers. Patio door installation requires expertise, and we would never use your home as a training exercise. In short, we provide some of the best new door installation in Charlotte.

Who do I talk to if I have a question or problem?

You can certainly speak directly with our lead installer, but we always give you other options, too. You will have direct contact information for your project manager and for our owners Brian & Sara Zimmerman. If you feel like even the slightest detail is being overlooked, we WANT you to call us.

Please also remember that we don’t take deposits and don’t ask for any payment until your patio door project is done – and done right.
