As a manufacturer, Royal Windows and Doors wants their customers to rest assured that they are receiving top-quality products that will withstand weather and time. Having just celebrated their 34th anniversary this past February, owner George Efthymiou credits their success to their commitment to quality and approaching customer service from a consumer’s perspective.

George has had quite the journey as an immigrant from Cyprus, to now running a manufacturing and retail sales company with two show rooms in Bay Shore and Commack. After moving to the States for graduate school and completing a Ph.D. in chemical engineering, George took what he thought would be a temporary stint at a factory job with some friends in order to support his family. As it turns out, he was in it for the long haul. After the original owners moved onto other endeavors, George’s two brothers joined, and together they grew the company. Today, their sister and nephew along with George’s son are also part of the Royal team.

Royal Windows and Doors provides design and installation services across both Nassau and Suffolk counties. Their products are designed and manufactured in-house. Royal’s priority is providing the highest caliber products to his customers, which to him means energy-efficient, durable, and long-lasting. What sets Royal apart from big corporate competitors and other distributors is that their customers know exactly where their product is coming from. The entire Royal team cares about providing customers with products that are best-suited to their needs, from the quality of their doors and windows, to designs that are sure to boost their homes’ curb-appeal.

If you won’t take our word for it, just take a look at Royal’s online reviews. Customers consistently praise precise measurements, attention to detail, the professionalism of the installation crew, and the outstanding quality and design of the products. George says that after a job is finished, they hadn’t been in the habit of asking customers to leave reviews of their experiences. Customers are so thrilled with their end results that they go out of their way to take the time to leave reviews. George’s approach to customer service is from a consumer’s perspective. He treats customers as he himself would want to be treated, and genuinely wants what’s best for their homes.

Over 34 years, Royal Windows and Doors has been awarded Bethpage Federal Credit Union’s Best of LI Award multiple times. Combined with high standards for quality and customer service, George attributes Royal’s success to a lot of hard work, a lack of friction between his business partners (which is easy to say when they’re your brothers), and his ability to solve problems – a skill he developed in graduate school. When asked if there was anything he would like to share with our readers, George said he wants them to know that “the best thing that a prospective consumer should keep in mind is that they can use the entire Royal team as a resource. Not only as a place that makes windows and doors, but as a resource to find information, get advice, and access designs.”

For your next home improvement project, you can be confident that Royal Windows and Doors will point you in the right direction and provide long-lasting products that are well-worth the investment.
