You know that feeling when you're staring at a leaky faucet at 2:00 AM and suddenly the theme music from This Old House starts playing in your head? It’s a specific kind of comfort. Since 2002, the cast of Ask This Old House has been the collective "neighbor who actually knows how to use a circular saw." They don't just show you a finished kitchen; they show you the grime, the stripped screws, and the "oh no" moments that happen when you open up a wall in a house built in 1920.
But things change. People retire. New faces show up with better cordless drills and different ways of explaining how a heat pump works. If you’ve tuned in lately, you might’ve noticed the barn looks the same, but the faces are shifting. It’s not just about Kevin O'Connor anymore.
The Core Crew: Who’s Staying and Who’s Stepping Back
The heavy hitters are still there, mostly. Kevin O'Connor remains the glue. Honestly, it’s impressive how he’s transitioned from a literal homeowner on the original series to the guy who can hold his own in a conversation about three-phase electricity. He’s the bridge between the professionals and us, the people who occasionally accidentally hammer our own thumbs.
Then you have Richard Trethewey. The man is a legend. If there is water moving through a pipe anywhere in New England, Richard probably knows its name. He’s been a staple of the cast of Ask This Old House since the very first episode aired. While he’s definitely taking a bit of a backseat compared to the early 2000s, his expertise in HVAC and plumbing is still the gold standard for the show. He’s the one who taught a generation of DIYers that "water seeks its own level" and "hot is on the left."
Tom Silva is the other pillar. Tommy’s "safety first" mantra isn't just a catchphrase; it’s a lifestyle. Even as he leans more into a consultative role, his fingerprints are all over the craftsmanship of the show. You’ll see him popping into the workshop to help with a complex jig or a tricky framing issue, reminding everyone that if you don't do it right the first time, you’re just making more work for yourself later.
The New Guard of Experts
The show has smartly started cycling in "the next generation." It had to happen. You can't expect the same guys to crawl into crawlspaces forever.

Nathan Gilbert is the standout here for carpentry. He’s a second-generation carpenter who brings a younger energy but the same "old school" dedication to finish work. He’s often the one traveling across the country now to help homeowners with deck repairs or built-in bookshelves. It’s a weirdly seamless transition. You don’t feel like you’re losing the Silva legacy; you feel like it was passed down correctly.
Then there’s Heath Eastman. Electricity is scary. Most DIYers won't touch a breaker box with a ten-foot pole. Heath has this way of explaining circuitry that makes it feel... manageable? He joined the cast of Ask This Old House to fill the massive shoes of the late Scott Caron and the occasional appearances by Allen Gallant. He’s practical. He’s fast. He doesn't judge you for having a "rat's nest" of wires behind your light switch.
The Specialized Pros
- Jenn Nawada: She’s the landscape designer who actually cares about drainage. Most people want "pretty flowers," but Jenn is the one telling you why your foundation is rotting because of your mulch bed. She’s been a permanent fixture since roughly 2015, bringing a much-needed focus on "curb appeal" that isn't just cosmetic.
- Mauro Henrique: The painting expert. People think painting is easy. Mauro proves it’s 90% prep and 10% actually moving the brush. He’s become a fan favorite because he’s incredibly meticulous.
- Mark McCullough: The mason. If it involves bricks, stone, or mortar, Mark is your guy. He has a very "no-nonsense" South Boston vibe that fits the show’s DNA perfectly. Watching him repair a chimney is strangely hypnotic.
- Ross Trethewey: Yes, Richard’s son. He’s the "Home Technology Expert." While the older guys are talking about cast iron pipes, Ross is talking about smart thermostats, solar arrays, and the "house of the future." It’s a necessary balance.
Why the Lineup Matters for Your House
The cast of Ask This Old House isn't just a group of TV presenters. They are working contractors. That’s the "secret sauce." When you see Tom Silva explain a miter joint, he’s not reading a script written by a PA in Los Angeles. He’s telling you what he did on a job site three days ago.
This matters because home improvement advice on the internet is, frankly, often dangerous. You see 30-second clips on social media of people "renovating" bathrooms using materials that will mold in six months. The Ask This Old House team is the antidote to that. They emphasize code compliance and longevity over "aesthetic" quick fixes.
The Roger Cook Transition
We have to talk about Roger. For years, Roger Cook was the heart of the outdoor segments. His exit from the show was a slow, heartbreaking process for long-time viewers who noticed his physical struggles on camera. In 2020, he officially stepped down as a regular cast member due to ongoing health issues.

The way the show handled this was incredibly classsy. They didn't just replace him overnight. They let him phase out, introducing Jenn Nawada and others while still honoring Roger’s decades of service. He’s still "part of the family," even if he isn't lugging bags of stone around anymore. It’s that kind of loyalty that keeps the audience coming back.
Misconceptions About the Cast
A lot of people think these guys are "too expensive" for the average person. While it’s true that hiring Silva Brothers Construction for your home renovation would cost a pretty penny, the advice they give on the show is designed for the budget-conscious homeowner.
Another big one? That the show is "fake" or staged.
Look, it's television. They have to light the room. They have to film things twice if a plane flies over. But the repairs are real. The "Ask" segments come from real letters sent in by people like you. When they show up at a house in San Antonio or Portland, that homeowner is actually getting a free professional repair (and a lot of free advice).
How to Actually Get on the Show
Want the cast of Ask This Old House to come to your driveway? It’s not a lottery. It’s a selection process based on the "teachability" of your problem. They don't want to just fix your sink; they want to fix a sink that represents a problem thousands of other people have.
- Be specific. Don't just say "my house is old." Say "my 1940s steam radiator is making a banging noise that sounds like a poltergeist."
- Photos and Video. They need to see the "bones" of the problem before they commit to flying a crew out.
- Willingness to learn. The show isn't Extreme Makeover. You have to be on camera, and you usually have to help with the work. They want to see you get your hands dirty.
The Longevity of a Brand
Why has this specific group of people stayed relevant for over two decades? It’s authenticity. In an era of "influencers" who buy a house just to flip it for content, the cast of Ask This Old House represents the actual trade industry. They advocate for vocational schools. They talk about the "skills gap."

They’ve also embraced technology without losing their soul. You can find them on YouTube, Instagram, and TikTok now, breaking down complex engineering into 60-second chunks. But the core remains the same: a bunch of guys (and now women) in a barn in Massachusetts trying to make sure your roof doesn't fall in.
Actionable Takeaways for Your Next Project
If you’re watching the show and want to apply their "expert" mindset to your own home, stop looking for the cheapest way to do it. Start looking for the right way.
- Check your "Grade": Before any indoor project, look at your landscaping like Jenn Nawada. Is water flowing away from your house? If not, your indoor renovation is a ticking time bomb.
- The "Rule of Three": When dealing with contractors, remember the Silva approach. Get multiple quotes, check references, and never pay the full amount upfront.
- Maintenance Over Repair: Listen to Richard Trethewey. Change your filters. Flush your water heater. It’s boring, but it saves you five figures in the long run.
- Safety isn't Optional: Buy the safety glasses. Use the hearing protection. Tom Silva didn't keep all his fingers by being "relaxed" with a table saw.
The cast of Ask This Old House continues to evolve, but the mission hasn't budged. Whether it’s Kevin, Tommy, Richard, or one of the newer pros like Nathan or Heath, the goal is education. They aren't just fixing houses; they’re building a more capable generation of homeowners. Keep watching, keep learning, and for heaven's sake, turn off the water main before you start poking at that pipe.
To stay updated on the latest episodes or to submit your own home for a visit, your best bet is to head directly to the official This Old House website or follow their official social media channels where the cast often shares behind-the-scenes clips of ongoing projects. Knowing who is currently on the roster helps you understand which expert to tag when you're looking for specific advice on Twitter or Instagram. Every member of the crew brings a different specialty to the table, so identifying the right pro for your specific "house headache" is the first step toward a successful DIY fix.
