I Found Free Money in the Tech House
Chapters11
The team sketches out an open-plan renovation for the living spaces and begins removing remaining walls, while debating the value of scrap copper and hinting at sponsorship from Seahoo. They tease the logistics of copper savings and the upcoming contractor work.
Linus Tech Tips scores DIY gold in a chaotic house crawl space, turning junk copper into a fraction of its value while keeping a sense of humor intact.
Summary
Linus and the crew dive into a messy renovation of a so-called tech house, turning a planned open-concept dream into a messy but entertaining scavenger hunt. They weigh the decision to salvage copper and wiring as potential value, while acknowledging safety and code realities. Throughout the crawl space explorations, they juggle humor with genuine puzzle-solving—identifying a mysterious 1,000-watt device, dodging hazardous wiring, and uncovering an alarm-related setup that baffles them. The team narrates working with licensed electricians later in the project and teases a future model viewer at tech.house, a companion site proposed by Dan from Flowplane. Sponsorship by Seahoo is interwoven, with mentions of the Doro C300 Pro V2 chair and its Dino Core system as the team shifts between heavy lifting and technical banter. The episode blends unexpected discoveries (hot glue, a red-tagged wall, and a “rabbit squirrel” rumor) with real-world lessons on why copper and wiring must be properly managed or reclaimed. By the end, they tally copper and wire salvage, admit some yards of progress and least-favorite tasks, and look ahead to plumbing work and material replacements. The overall vibe stays light and chaotic, but the show clearly communicates the not-always-glamorous labor of upgrading a home while keeping fans entertained.
Key Takeaways
- Copper salvage value: roughly 3–6 dollars per pound for copper scrap, with a total estimate around 45 dollars for a particular section, illustrating how salvage income is real but modest.
- The crew discovers a bizarre 1,000-watt unit labeled 440 OCV, likely related to an old alarm system, highlighting odd electrical configurations that professionals would never leave in a finished home.
- Proper demolition and remediation trumps DIY splices: electricians insist on junction boxes and code-compliant wiring rather than reusing wall cavities with spliced cables.
- Planning and safety matter: gas lines should be colorcoded and checked; several near-misses and dusty crawl-space work underscore why licensed professionals are essential for the big removals.
- Salvage momentum slows but keeps going: despite difficult access and messy conditions, the team completes core pulls from the crawl space and transfers attention to plumbing and rest of demo.
- The tech.house companion site (tech.house) offers a model of the house by room or category, showing how the production team is integrating digital, consumer-facing updates with the physical build.
- Sponsored integration: Seahoo’s Doro C300 Pro V2 chair with Dino Core system is highlighted as a tool-friendly addition for long, physically demanding shoots.
Who Is This For?
Essential viewing for DIYers and home renovators who enjoy the chaos of a live demolition, plus fans of Linus Tech Tips who want behind-the-scenes truths about salvaging materials and coordinating with licensed pros.

As tends to happen on any renovation project, everything about the tech house is taking longer than we'd like. But we have finally settled on a plan that's going to take the living room, dining room, kitchen, and family room, and cliche incoming, open them up into one giant space that is perfect for entertaining. And now that we're certified as best as free, we're ready to take out what's left of these walls here so our licensed electrical and plumbing contractors can come and do what they do. But before they do, there's an awful lot of copper lying around in here and probably even more under the floor.
Do you think this is worth anything? As plumbing, not so much. The copper's only good for about 50 years and we're pretty close to 40 on this house. Right. So, we don't want to leave this in the wall for the next guy. Exactly. But as scrap, it does have some value. It's probably between 3 to six bucks depending on quality and where you take it. Really? So, we're sitting on a gold mine here then. I mean, a copper mine. I get it. And now I'm going to take a seat on this segue to our sponsor, Seahoo.
Their Doro C300 Pro V2 office chair introduces something they call a Dino Core system for full body dynamic support. So the chair adjusts as you do. Learn more at the link down below. You and I can make our dreams come true together. IT SHOULDN'T TAKE LONG FOR US TO PULL UP THE REST OF these walls and extract anything of value. That's going to leave a fresh slate for the contractors and if we're lucky, even help take a chunk out of the cost of some of the new materials. I'm feeling good about this. And that positive attitude is going to serve you well in the crawl space.
I'm going in the crawl space. Yeah. Me and my team are going to work up here. Oh. And uh we'll let you get down there. Why do I always end up in the crawl space? Well, your name's on the on the channel. I don't follow the logic. Okay, I'll give you one guy. One guy. Are any of you even going to fit in there? Yeah, if I look taller, he won't pick me. Why is everyone here huge? So, this is my light source, then. This is your light source. All right, brilliant. Wait, this is all you're giving me?
How am I supposed to cut any of the copper piping down there? Uh, actually, I want to leave the copper until a little later in the day so we still have like water for the bathroom. Oh, that makes sense. So, just start with the wiring and we'll go from there. Can do, boss. Oh, wait. Can I have the one that has pliers on it instead of just side cutters? You may. Do I get knee pads? Yes. I should come up and get dressed properly in Oh, sure. All right, I'm ready. You look pretty hardcore, right?
Watch out for gas lines. Oh, yeah. That's a really good point because for whatever reason, the gas lines in this house are not colorcoded yellow. That's not a thing. It is a thing. It's not in the code. I checked this morning. Oh, so it's just an informal thing, I think. So, Oh, all right. Well, it's in someone's code, I'm pretty sure. I'm kind of thinking we go through methodically. I was told there's a rabbit squirrel down here. Oh, good. I mean, I don't see one, but I think that's the thing about rabbit squirrels is you don't see them.
I CAN'T SEE UNTIL THEY'RE ON TOP OF YOU. LIKE, IS THE plan just to pull out everything? These seem perfectly useful. Like, do we just leave them here? They're very handone by the previous. Yeah. Is that Are those crutches? Oh, what the second pair of crutches? What the hell? Right when you spotted the other crutches. I spotted the ones right above your head. Weird. Why are there so many crutches in this crawl space? These are wooden crutches. How did I not spot these before? I missed so much treasure. Okay, so now followup question. Yeah. Is any of this structural?
This This can stay Yeah. So fine, but that little half stud can go. We need the wires off the wall and in a pile, right? Yeah. Okay. Ultimately, they'll end up on the scale in the garage. This guy just could not decide what fasteners to use for things. I think I just turned off the water to the house, which technically we don't need to do yet. All right, let's go find where that goes. That blue thing. Oh, you saw the blue thing? Oh, I'm trying to figure it out. I think it's the main water line coming into the house.
I'm wondering if it's an airline for the garage. I don't think so. So, I'm just going to go cruise and find the other end of this other blue thing. Okay, it is the main water line coming into the house. For some reason, it comes in way over there, then comes way over here, then splits off to where it needs to go. Even though this is not a very central location for it, so sure. Either way, we're not cutting it. Dad doesn't want me. So, I'm with I'm stuck with you guys now. I got fired, eh?
Yeah. So, I just cut out some what cables or something? Yeah, just cut everyone but the big thick black one. Just don't cut this one or anything that looks like this one. This is the mains going into the house. So, if you want all the electricity, this is the one. Will they give me like superpowers or something? It might cut the big block. Got it. Uh, the reason we can't just reuse everything is because we have to put junction boxes into the wall everywhere a cable would be spliced and that would look absolutely ridiculous in our house and no electrician worth their license will do it.
Just found another random outlet. So, a 20 amp freaking why. All right. Well, it's coming out. Whatever it is. Well, if I just cut things from down here, then they could just pull them up up there, right? Oh, those are going to be a hazard for my poor knees and elbows and hands. Feel like once I get going, I'm going to go pretty fast, but I'm not going yet. You know what I'm saying? I think we're just going to start cutting. Okay, we're just going to start we're just going to start hauling. Sean, old owner has cute little cable management on some of these things.
Got a adorable little finishing nail in here. All right, this one here seems to be the one that he used to run that weird extension cord over to the shed outside. All right, you go, girl. I'm going to undo that. That was so random. My left hand. Look how many nails are in this. Yep. 1 2 3 4 5 6 7 8 9 10 11 nails in that section of wood. I have the power. You have the power. Doing all right? Yeah, I'm doing great. I uh get to re-break all the cobwebs that were here before that are back now with my face.
There's a license plate down here. Yeah, I saw that. I found Oh, I found more treasure. No idea what it is, but it's from Sears. Yeah, some kind of roll of something. There's two of them. Oh, three. Oh, no. This is just a tree. Trying to figure out how this thing comes out. Oh, there we go. Okay. There's nothing below me, right? A ladder. Okay. Not ideal. Towards the front door. Yeah, there's a blue and a black wire. They're just kind of loose up here. Where do they go? Okay. Hey, I'm going to go look by the front door.
Like between the front door and the utility room. OH, I GOT YOU. WHOA, NELLY. What the crap am I looking at here? I got yet another flipping duplex receptacle. And then I think I got your looks like some kind of transformer. I mean, you can pull the wire down. It's fine. Hold on. Hold on one sec. I just I'm curious now. It was connected to a dial up here. It is no longer. Is that a jump rope? It's like a jump rope just hanging from a pipe. This might just come right out. I think I GOT IT.
OH JEEZ. Holy crap, it's heavy. Okay, so that was plugged into a switch by the door here. Here you go. What in the hell? You're going to need two hands, sir. My god. And that's where the blue and black wire went to. That's the blue and black wire. All it says is 1,000 watt. 1 to 1,000 watt. Is this 440 volt? Holy. That's the only number I can see. 440 OCV is the only V anywhere on it. I don't know what he was doing with it, but you guys should have seen the rat's nest of wiring that was going in and out of it.
And here, I thought we found all the interesting stuff the first time I went down there. I should have looked up. According to uh Nathan, this is probably from an alarm system. An alarm system. Does it electrocute the person that touches the doororknob or something? Maybe. Wow. Why does it need 400 volts? I don't know. to electrocute the person who touches the doorork knob. I guess could be. Also, there was something up here in the roof. I think you guys might have taken it down already, but it had like an absorbent amount of hot glue on it.
Oh, yeah. the uh pot. Yeah, that like professional levels of hot glue. My abs, dude. Look like sitting like this a lot of the time. Yeah. Where's all my tools at? My collection is growing of things that I need to carry around with me. I want to try and pull that box off the wall. So, I'm going to pull this cord and see if I can just pull the box off. Ready? Well, the pulling worked. Uh, didn't pull all the way, though. This corner is officially wire free. Cool. What was this? Oh, is this just the beefiest speaker wire in the world?
But where would it go? Free. Wait, wait, wait. Hold on. Are you guys pulling on those uh big black kind of speaker wire looking guys? Okay, give me one sec. Give me one sec. It's uh funny story. It's tied up with a skipping rope. I mean, I guess nothing's a surprise about this place at this point. Okay, go ahead. Oh, man. All right. Good stuff. Mr. Pancret, yo, why is there a wire coming out of the stove down below? Yes, that is what's happening. Okay, why? I mean, it could be the same reason why there was a wire coming out of the drywall plug or dryer plug and going into the garage.
You could get Lionus to check it out. Uh yeah, this is what was being used to cable manage that situation. Home. Homemade. Homemade like everything else in this place. So, look at what's going on here. We have our stove. There's a wire coming out of it. Oh, yeah. Yeah, bud. Can you guess where that goes? I think it's probably the AC. Uh I saw something going kind of that way. Uh wait, wait, wait, wait, wait. There's a plug out here. Isn't there a dire plug? Yeah, I think that's the one. That is not how you wire a house.
No. Heavens no. But it is how you wire an AC. It's not even the AC. It's just the AC's in the different plug. Oh, wait. Yeah, the AC is not even using the dryer plug. Maybe it did at some point. Maybe he had a Maybe he had a little baby size hot tub here. I don't know. We're updating. How's the crawl space going? Oh, yeah. Uh, we're making a video, remember? I think I'm about halfway done. Yeah, electrical, but I haven't touched any of the plumbing yet. Yeah, we haven't done yet. Do we have a plan for that?
Turn off the water and start chopping. Hell yeah. Oh my god. That's the plan, I'm going to skip back. You're a little dirty, bud. Some of this is just like completely untothed itself. We didn't do that. Oh my goodness. That's Did we have a potential house fire? Hell yeah. Actually, you could. It looks like it burned right there. It did burn. Yeah. Yeah. Look at the way it's the coating is melted. Oh my goodness. It's crazy to think that guy was like this close from just Wow. Like that. Yeah. That like legitimately almost caught fire.
Yeah. But with that being said, it looks kind of tinged up there. I think that's just like watering grass. Either way, it's not good. I'm not going to try to like eat it or anything to find out. So, no, you're no fun. Did someone decide to come down and join me, the mall people? I'll take that as a no. Here it is. Here's that dryer outlet that Jordan was asking about on the outside of the house. So, you can see it's just it's just chilling down here. And yep, it goes right over there where the kitchen is.
So this this is it. Time to disconnect this mess. Sir, you do not fit down here. A lot taller. we made it. We made it. I got some of the light fixtures that were down there taken off the walls and out of there. And we only managed to break one bulb. This is This is what passing the torch looks like, right? It's okay. I I've had to use hockey equipment in high schools before. Going in. Hello, Mr. Lionus. Wild Justin appears. Yes, it's my turn for a shift down here. Oh, cool. Okay. Well, your timing is excellent because it is just about time to take all this stuff and start hauling it up.
Treasure. Oh, it's kind of weird. There's more less than I thought and more than I thought there would be inside a house. There you go. All right. I want to see how I did here. Is that it? That's it. What the crap? Well, I thought I felt like I had a lot more than that, you know. At least I got my jump rope. Truly my the consolation prize to end all consolation prizes. Hey, Jordan. Yeah, tell me to go get the copper piping. Go get the copper piping. Okay, I'll hop to it. Boo. So, is this the plan for the copper?
Sure. Sorry. Is Is it or not? I have two saws. That's kind of the plan. All right. Rock on. We can do SOME WE CAN DO some weighing here. Hey, this is great, you guys. Damn, dude. You know what, though? This is going to be kind of awesome. I can I can actually kind of see it now. Like you got the island over there. You got like the the the thing here and the seating area here. You got like the sitting area there. Sick. While we're here, we should unveil the awesome tech house companion website that Dan from our Flowplane team has been working on.
Just go to the tech.house. We'll have a link down in the description. And you can check out a model of the house from any angle. See what products we're using by room or by category. And we've got even more features in the works. There's even a little robot zipping around on the lawn. Check that out today. We haven't seen our squirrel friend anymore. Ah, he'll be back. they always come running back. I think the the the plumbing is going to be the bulk of the actual copper weight anyway. Like, is this even worth anything? Oh, no.
45 bucks really for that section. That's a low number, but that's that's times $3. Okay, we have most of the wire out apart from upstairs where it's very very hot. Nice. It's getting hot in here, so take off. Sorry. What now? Uh, now I guess we got to do the plumbing. Let's do it. So, I think I found the main water cut off. And I'm thinking before I start cutting anything, we should make sure it's the main water cut off. Okay. Why don't I go down there and then you'll try with the sink and try to try to sink it and then then if it's correct then we can start popping.
All right. Let's go, boys. Water's on. Okay. One sec. I can't believe they put these in here by mistake cuz they're air filters. People like me should definitely have power tools. Here we go. All right. I'm I'm heading to it. I'm I'm going to it. Get it. Get it. Is he yelling to no one or Okay, here we go. Oh, that was definitely something's off. All right, success. That's definitely it. So, now what? I just cut off everything else. Uh, yeah. That's crazy. Not the drainage, but yeah. Okay, man. There's going to be so much freaking water down here.
All right. Well, there's no time like the present. Oh, boy. fixed it. Oh well. Sorry for the disappointment, Sean. I was expecting to uh to cut something here. Instead, I ripped it apart with my bare hands. Now, they cut it up top already, I guess. Anyway, there's um not actually that much down here. I don't know how much we're going to get for this, but my pants are wet, so we have that going for us. Ow. Oh, ew. Oh, it's gross. It's yellow. Toilet line. No, no, no, no, no, no, no. This is freshwater line.
Don't even. Very funny. Oh, hi there. Hi there. How are you? I found a hatch. There's no buried treasure, though. Hello. Oh, just a Linus. I mean, that's pretty treasureful, don't you think? I suppose. Watch out these nails here. Oh. Oh. Oh, jeez. Jeez, my eyes. What? What's What's this hatch for? I don't know. It was under the tub. I found a broken glass in it. Okay. Don't look at that. Oh, good thing you said something. Hi there. Are you You put it the wrong way. All my copper's over there. I got so much of it.
You just can't see it. I got I got so much copper down here. It's like It's crazy. I think you might be lying. I've just realized that our uh vents don't go anywhere. It's literally just into the wall. Same with the one for the bathroom here. They literally go nowhere. So, the walls can breathe. My god. It does go to the vent. The vent. They're using the wall as vent. And this is like a channel here to the Oh my god. I've seen that before. Wow. That's interesting. Yeah. Oh, hi there. It's just pulling out more copper.
It's slow though. That's why I always say you'll NEVER CATCH ME COPPER. I want you to trace follow this exact like Never mind. Forget it. Forget it. I'm actually ready to bring up some copper. All right, we're trying to make the pile. That is some very green water. Maybe I should have cut this into smaller pieces. I started getting lazy toward the end and my sawz all started getting dull. All right. Play where that came from. If someone wants to stand up here and I can pass some copper, might go a little faster. Last one.
Got it. Beauty. As well-intentioned as your doggy scale there was, I don't think we're going to be able to weigh this. No, I think we let uh Alex take it to the recycler and he can tell us how much it weighs and then we'll react here. Yeah, we'll react both ways. All right. Go. Oh, this is terrible. Oh. All right. Okay. The other way. Ready? And that's awesome. Really? Either way, we made this much money. Yeah, sort of. Time to spend it on replacing everything we just tore out. Pretty much. And time to replace this segue to our sponsor, Seahoo.
