With the winter season fast approaching, it is essential to ensure that each homeowner takes the necessary steps to insulate water supply Pipes. This is especially important to do it for pipes that are exposed to harsh elements, as they are prone to freezing in cold temperatures.

One of the ways you can ensure that your pipes are winterized is by insulating them. Below, we provide two methods that you can use to insulate your water supply pipes. Read on to learn how you can prepare for the winter.

Method 1: Insulation Wrap

1. Secure Insulation Strip

Place the end of the insulation strip onto the pipe and secure it with a piece of duct tape. This will ensure that it doesn’t move or unravel your work.

2. Wrap the Pipe

Using the strip, wrap it around the pipe, being sure to overlap the previous loop with 1/2 inch coverage. Doing so will ensure that no areas of the pipe will be exposed.

3. Tape the End in Place

Once you have covered the entire pipe, tape it in place. If extra insulation pipe wrap is left over, cut it off to leave just enough wrap to tape down on the pipe.

Method 2: Foam Cover

1. Position the Foam Pipe Cover

Place the foam pipe cover completely around the pipe. Make sure that the pipe cover is large enough to close up around the pipe.

2. Tape the Seam

Secure the pipe in place by sealing the seam. Most pipe covers come with a self-adhesive strip of tape that can be used for this step. If not you can also duct tape to cover the slit.

3. Cut off Extra Foam

With the seam closed up, cut off the excess foam at the ends using a utility knife to do so.


  • You don’t have to insulate all pipes, only the ones that are placed in spots where heating isn’t provided.
  • Check your pipes for leaks before wrapping them.
  • Know the R-value of the insulation material you use. The greater the value, the more effective it will be in insulating your pipes.
  • Be sure to clean your pipes of residue or dirt before beginning the project.


  • In the event of a frozen pipe, contact your local plumber, who will know the safest approach for thawing your pipes.
  • If you clean your pipes before applying the insulation, ensure they are completely dry before beginning the work.
