Why insulating water pipes is a smart home upgrade

Homeowners often look for ways to safeguard their investment, whether that means updating a property to match current trends or staying on top of basic maintenance so the house does not deteriorate.

Thinking ahead and preparing for possible problems is an important part of responsible home care. While that kind of foresight takes experience, homeowners can also learn from others and identify steps that help prevent issues before they start.

One problem worth planning for is frozen pipes. An especially cold winter brought that risk into focus across many parts of the United States, with temperatures in the Northeast, Midwest and mid-Atlantic running well below normal. That kind of weather can set the stage for serious pipe damage when the mercury drops.

The harsh cold also prompted many homeowners to deal with problems they had not expected, including frozen pipes. Pipe insulation is an important maintenance step that some homeowners may not have considered, but it offers several compelling reasons to add it to the home improvement list before cold weather returns.

• Insulation helps keep pipes from freezing. Water that freezes inside a pipe can trigger a chain reaction that causes the pipe to expand. As the pipe expands, pressure builds until it may burst. Insulating pipes helps prevent that from happening. Pipes hidden behind walls are harder to insulate and are usually best handled by a professional. Pipes along exterior walls should also be insulated so they are less likely to freeze during prolonged cold spells. Exposed pipes in attics, basements and crawl spaces may be manageable for some homeowners, though beginners may still prefer to hire a professional.

• It can lower utility costs. The U.S. Department of Energy says insulating hot water pipes is a practical way to save energy and money. The DOE notes that pipe insulation reduces heat loss and can raise water temperature by as much as 2 to 4 degrees. That can allow homeowners to set water heaters at a lower temperature, reducing energy use. Insulation also helps water reach the desired temperature faster when a faucet or shower is turned on, which can cut water waste and lower bills.

• It may help prevent mold. Insulated pipes are useful in more than just cold weather. Experts at Aeroflex note that pipes can develop mold problems when they sweat in humid conditions, much like condensation on a cold drink. That moisture can drip into surrounding areas, including inside walls, and contribute to mold growth. Mold in the home has been associated with a range of health concerns, including respiratory problems. Insulation helps limit the condensation that leads to those issues.

• It is relatively affordable. Compared with many home repairs and renovations, insulating pipes, especially exposed ones, is a fairly low-cost project. Pipes inside walls can be more expensive to insulate because of the work needed to access them and finish the job afterward, but the expense can still be worthwhile. That is especially true for pipes along exterior walls, where insulation may help prevent much costlier damage later on.

Insulating pipes is a worthwhile project for nearly any homeowner, and it can be especially useful in regions that experience extreme winter and summer weather.
