How Do You Waterproof Outdoor Extension Cords

Many people don’t have a budget and often ask, “How do you waterproof outdoor extension cords without spending too much one money?”

So for them, we might have a cheap alternative in the next method to keep their extension cords from getting wet.

  • Method 4: Go For Smart, Easy, And Cheap Bottle Method!

First of all, you will need to go to your kitchen and grab yourself:

  • A big empty plastic bottle or 2-liter soda bottle
  • Pair of scissors or box cutter
  • Utility knife

The plastic bottle method is not only good for monsoons but also for the winter season. It can cover all your extension cords without letting even a drop of water inside the bottle.

Below are the instructions:

Step 1: Take the utility knife and cut the empty bottle about half-way in between the bottle. Make sure the cut is only 1/4″ around the bottle.

Step 2: In the second step, grab the scissors and create a round hole at the end of the cut. The hole will keep the extension cord fixated in one place.

Step 3: Then, slide the plugs and connections safely inside the plastic bottle. After doing so, the cords will be left hanging out of the round holes.

That’s it! You are done!

By following these three easy and simple steps, you will surely get desired results. If you don’t have a plastic bottle, then an old milk plastic bottle or margarine/butter tub will work fine as well.

  • Method 5: Try PVC Pipes And End-Caps Method!

Materials you will need:

  • 1.5″ pipe
  • 2″ pipe 
  • End caps
  • Rotary tool or hacksaw or grinder

PVC pipes and end-cap method is yet another genius way to lock out the water and keep your wires and connections protected from the elements like water.

This method will require more time and few tools, so you will have to take a day off from your work to begin this DIY.

Nonetheless, this project is effective.

The Design And Purpose:

  • Reduce the risk of theft
  • Stop intentional disconnects
  • Prevent accidental disconnects
  • Weather protection

Step 1: Get the extension cord you will be using for this project.

Step 2: Use the connected cords to size up the pipe you need.

Step 3: Bring drill bits bigger than the power cords

Step 4: Now, measure the length of connected cords. Make sure to leave some extra room around 7″ inside the large pipe. Your smaller cords/plugs don’t need as much length.

Step 5: Next, cut pipes to desired length and sand down the rough edges to smooth. You must do this to avoid it from cutting and ruining your cord.

Step 6: Time to prepare the end caps! So drill the hole in the end cap. Make sure it is bigger than the cord.

Step 7: Then, draw lines from the hole to the edge and repeat downsides.

Step 8: Now, cut the drawn lines with a grinder, hacksaw, rotary tool, or any tool you want. Then, smooth the edges to prevent the cord from damage.

Step 9: Put the extension cord in the pipe and close it with the end caps. To slide the zip ties, drill a hole through both sides of the pipe and cap. (Make sure you are doing this after removing the extension cord.)

Step 10: Now, put the cord back through the cap and take a final walkthrough of how it might look.

Step 11: Seal it with the zip ties to lock the end pipe onto the pipe tightly.


So this is how to protect outdoor extension cord from rain!

Things To Keep In Mind While Working:

  • Make sure to go for bigger pipes if your plugs don’t fit the smaller ones.
  • To avoid any confusion, label the pipes to understand which pipe goes on which end.
  • Method 6: Worry Less About Rain By Using The Bucket Method!

Materials will need:

  • Two big buckets
  • Some bricks to hold
  • A shovel

Step 1: Make sure to use good quality and strong plastic buckets for this project.

Step 2: First of all, you have to take bucket one and place it in the ground. Make sure to place it upside down.

Step 3: Now, set the part of the connected extension cords on the top of the bucket. If it does not stay still, then you can tape it.

Step 3: Next, get the second bucket and slide the opening face down on the first bucket to seal the extension wire.

Step 4: If your region is too windy, you can either dig a tight-fitting hole around the first bucket and place the second bucket, or else you can use bricks to support them. Make sure to push the first bucket deep into the mud as needed.

So now, it can rain all it wants without getting your extension cord wet during the monsoon. But if it gets windy, it might tip it over so, block it with some extra blocks.
