It seems every time I flip on the boob tube, there’s another happy couple—well, generally happy, but momentarily disgruntled couple—undergoing a home reno while TV cameras roll. Welcome to prime time, where homeowners and professional renovators flip the ugly, the outdated, the unlivable into a contemporary nest in less time than it takes most of us to re-tile a small bathroom.

If home reno shows have done one thing well, it is to expose the bad guys in the business. But while they have raised the status of a few good men, and women, these shows have also given off the impression that renovation is a card game where you need to call bluffs and gamble your savings.

Money Blue Book, a blog about “smart investing, frugal living and credit card offers” offers up what it considers the best house-flipping and house-hunting TV shows. But it should be noted that “best” here refers to “most entertaining.” For example, here’s Blogger Ray (no last name) on A&E’s Flip This House: “I love the show and found it irresistibly entertaining due to the endless stream of scam and fakery controversies [including] Atlanta “real estate developer” Sam Leccima and his Season 2 housing-flip scam debacle. His on-the-air house flipping prowesses were later exposed and discredited as shams by news investigators when it was revealed that he had duped many investors in an elaborate flipping cover up.” “Ray’s” passionate analysis continues on the site.

But I don’t mean to just focus on the negative. Instructional TV has come a long way since the days of Bob Ross reminiscing about wartime while painting his latest water-colour masterpiece. While we’re inundated with a few too many shows these days, there are at least a few worth your half hour.

Canada’s HGTV carries a wide selection of less glamorous, more realistic reno shows, even if they are slightly sped up—hey, come on, it’s television. Most notable is Holmes on Homes, starring contractor Mike Holmes as the tough-talking, bicep-wielding here-I-come-to-save-the-day pro.

The original reno shows belong to This Old House, the New England program starring everyman Norm Abram. Beginning in 1982, this is probably television’s longest-running reno show.

Of course, we can’t really talk TV without mentioning the Kenny Rogers of DIY, Bob Vila. This guy can sell, and unlike us regular folk, his hair never seems to grey and his golf shirts never seem to fade.
