Before You Start
- Before installing a flagpole, check local regulations or your HOA to see if you need any permits. Be aware of any height restrictions that apply to your property before installing your flagpole.
- The size of your flagpole should be appropriate for the size of the flag you have.
- The soil in your intended location should be stable enough to support the weight of the flagpole.
- Pick a visible, open spot away from trees, power lines, and buildings.
How to Install a Flagpole
Dig the Hole
Using your post hole digger, dig a hole in your selected spot. Make the hole about two feet wide and about thirty inches deep. Add a three-inch layer of gravel at the bottom of the hole to help with drainage.
If there are any underground facilities in your area, contact your local utility company before you begin.
Place the Concrete Form
Measure the depth of your hole to make sure it’s at least thirty inches. Measure the concrete form and trim it to a couple of inches longer than the hole depth. Place the trimmed sleeve into the center of the hole. Use a level to make use it is straight on the sides and even across the top. Use wood stakes to hold the form in place. Keep the inside of the ground sleeve dry and free of debris by covering the opening with plastic or another protective material.
Pour the Foundation
Fill in around the concrete form with soil and tamp it down as you go. Fill the hole completely, leaving the upper part of the sleeve exposed. Once the hole has been filled, it’s time to mix your concrete and set your pole.
Assemble the lower section of the flagpole so that it extends above the height of the concrete sleeve. Place the base pole in the center of the sleeve and atop the gravel base. Level and support the pole.
Fill the sleeve one-third full of water. Add the fast-setting concrete directly from the bag into the form. Continue filling until the mixture is at the top of the form. If the mix is dry at the top, add a little more water, as excess surface water is not an issue. Recheck the pole to make sure it is still level. The concrete should set within fifteen to thirty minutes.
Assemble and Install the Flagpole
Assemble the flagpole according to the manufacturer’s directions. Many flagpoles today are telescoping, meaning they can be installed, lowered, and extended easily. Simply place the unextended flagpole into the base that is in the concrete base. Attach the flagpole finial top and secure with a wrench. Depending on how tall your flagpole is, you may be able to fly one or two flags. Attach them to the steel clips that are attached to the top of the pole. Raise the top section if needed to clip the second flag.
With your flags now attached, begin to extend the flagpole sections, twisting them to lock into place. Once the last section is locked into place, your flagpole is now installed.
Flag and Flagpole Maintenance
Clean the pole occasionally to maintain its appearance. Examine your flag for wear and replace if it is torn or faded. Most flagpoles are made from aluminum that is very resistant to inclement weather. You can clean the pole with mild soap and water. You can also polish to restore the shine. Check the base annually to make sure it is still sound and isn’t cracked. Lower the flagpole before severe weather to prevent damage.
Disposing of an old or worn-out flag—especially a U.S. flag—should be done with respect and dignity. Many American Legion, VFW posts, Boy Scouts, and local fire departments hold flag retirement ceremonies. You can attend or drop off your flag for them to retire it properly.
