Millennials were more likely than any other generation to describe themselves as handy around the home, according to a survey by the home improvement site Porch.com. However, the survey also found that young homeowners' confidence on their ability to make repairs and upgrades wasn't always matched by knowledge and experience.

A total of 69.2 percent of millennial respondents in the site's survey identified themselves as at least somewhat handy. Respondents identified as Generation X or baby boomers were less likely to self-identify as handy, with 61.6 percent of the former generation and 61.4 percent of the latter generation saying they had at least some home improvement skills.

Young men were most likely to consider themselves handy, with 78.6 percent of millennials saying they had some home improvement skills. This share was considerably higher than male baby boomers (69.8 percent) or Generation X members (65.6 percent). There was less variation among women, with 55.2 percent of baby boomers, 58.6 percent of Generation X, and 60 percent of millennials saying they were handy.

The site suggested many young respondents might be overstating their skills or suffering from the "HGTV effect." This refers to a trend of people purchasing a fixer-upper, and sometimes regretting that decision, because popular home renovation shows on the network make the upgrades look easy.

While millennials have begun purchasing homes in larger numbers, they may also have less experience in home improvement than those who have already purchased a home and gotten a sense of their own abilities. In the Porch.com survey, millennials were more likely than the other generations to say they did not own their home. A total of 41.3 percent said they were renters and 11.2 percent lived with their family.

Less than half of the baby boomers and Generation X respondents in the survey said they did home repairs on their own, while 55.2 percent of millennials said they did. Generation X respondents were the most likely of the generations to say that their partner or spouse completed repairs, with 39.5 percent saying this was the case; 30.1 percent of millennials and 29.7 percent of baby boomers said a partner or spouse did repairs.

Millennials were the least likely group to call for a handyman when a repair was necessary. Only 7.2 percent relied on these professionals, compared to 13 percent of Generation X and 24.8 percent of baby boomers. Porch.com said this result may be due in part to older residents making more complex upgrades to their home to help them age in place.

When it came to completing a repair, however, millennials were less likely to have direct experience. Baby boomers were 15.5 percent more experienced than millennials on average, and millennials were less experienced than other generations in 13 of the 21 repairs included in the survey.

For example, 79.5 percent of millennials said they had fixed a running toilet, compared to 83.7 percent of Generation X and 87.9 percent of baby boomers. Forty-two percent had replaced a kitchen sink, while 53.2 percent of Generation X and 58 percent of baby boomers had done so.

However, millennials were also more likely than other generations to have completed their own home entertainment upgrades. Eighty-six percent said they had set up a Wi-Fi router, compared to 79 percent of Generation X and 77.3 percent of baby boomers. A total of 59.7 percent had mounted a TV, while just 41.5 percent of Generation X and 32.7 percent of baby boomers had done the same.

Millennial know-how varied in other topics not related to home improvement. Young respondents were most likely to say they had changed their vehicle's oil on their own or cooked for a dinner party, but least likely to say they had prepared their own income taxes or hemmed a pair of pants.

The survey found that while most respondents from each generation were able to identify individual tools and their uses, millennials were typically most likely to make errors on the quiz. For example, 18.1 percent of millennials were unable to correctly identify the difference between a Phillips head and flat head screwdriver, compared to 11.4 percent of Generation X and 8.7 percent of baby boomers.

Knowledge of home improvement also seemed to be affected by one's living situation. Those living in mobile homes were most likely to do well on the home improvement quiz, answering 72.2 percent of the questions correctly. Those living in a house had a correct response rate of 69.9 percent, while condo dwellers answered 67.4 percent of the questions correctly and apartment tenants correctly answered 63.1 percent of the questions.

Those who owned their home answered 70.5 percent of the questions correctly. This edged out the correct response rate of those living with their family (67.1 percent) as well as renters (66 percent).

Porch.com collected responses from 1,010 American adults for the survey.
