Flags, Flagpoles and More for Homeowners

For homeowners, we supply retractable awnings, mailboxes, address plaques, and other items to complement the style of your house. Our residential products add beauty and functionality to your home.

How do you know which height of flagpole is right for your home? Generally, in residential settings, flagpoles 20 and 25 feet in height are compatible with most one and two story single family dwellings.

We are sometimes asked whether you need a permit to put up a flagpole, or a flagpole over a certain size. The answer to that is that it depends on the zoning laws in the area where you live. Some areas require a permit if you want to install a flagpole of more than 20 feet in height. When in doubt, check with your local zoning office to see if you need to apply for a permit. We can also provide you with more information about flagpole sizes and zoning for the areas we serve.

Our awnings have stood apart as the finest awnings made. Each awning is individually crafted to fit the customer's exact needs and tastes. Add traditional style and timeless elegance to your home with a Classic Mailbox from Gaines Manufacturing.

The mailboxes and address plaques we offer are made by Gaines Manufacturing, and are crafted from aircraft-quality aluminum and brass. They are powder-coated for a lasting finish and come in many different colors and classic styles to complement your home’s architecture and colors. Whether you choose a post-mounted mailbox, a wall-mounted mailbox, or one of our beautiful address number plaques, you’ll find that they are durable enough to last for years and age gracefully.

Commercial Flags and Flagpole Installation

CJ Flag & Son offers flag pole sales and installations for commercial customers in the Lindenhurst area. Flagpoles complementing commercial buildings can be found in sizes 20 feet and upward, and we can help you decide what size to choose that will best complement your property.

When it comes to choosing what flagpole height you need for a commercial building, the building size and the size of the grounds are the deciding and most important factors. For office building flagpoles, 40 to 60 feet in height are impressive enough to add a definitive corporate statement.

Another important consideration is how many flags you plan to fly at your place of business. Many companies will use two poles and fly the US and state flag. Another option is to use three poles and fly the United States flag, state flag, and your company’s own corporate flag or banner. Flagpoles can also be used at entrances or gateways or along drives leading up to corporate headquarters to create a dignified impression on visitors and customers.
