It could be groundwater, bulk water 202 00:09:23,100 --> 00:09:24,433 from rainwater coming in. 203 00:09:24,500 --> 00:09:27,066 It could be a plumbing leak. It could be a toilet drain. 204 00:09:27,133 --> 00:09:28,566 It could be...condensate. Right? 205 00:09:28,633 --> 00:09:31,066 There's a lot of things may be coming from inside or outside. 206 00:09:31,133 --> 00:09:32,433 We don't always know. And a lot of times 207 00:09:32,500 --> 00:09:33,900 it's in hidden spaces like behind drywall. 208 00:09:33,966 --> 00:09:36,366 Kevin: Right. So how do we find it if it's behind drywall? 209 00:09:36,433 --> 00:09:38,000 Ross: So the first thing we typically do 210 00:09:38,066 --> 00:09:39,566 is when we're doing a home energy assessment, 211 00:09:39,633 --> 00:09:41,900 we're thinking about thermal imaging cameras like this. 212 00:09:41,966 --> 00:09:43,800 This is going to see surface temperature. 213 00:09:43,866 --> 00:09:45,333 And what we're typically using that for is 214 00:09:45,400 --> 00:09:47,766 for insulation to see do we have insulation in walls 215 00:09:47,833 --> 00:09:49,400 and in roofs and stuff like that. 216 00:09:49,466 --> 00:09:50,766 In this case, though, a byproduct 217 00:09:50,833 --> 00:09:54,100 is we can also see water because water is typically going 218 00:09:54,166 --> 00:09:56,033 to be at a different temperature than the air. 219 00:09:56,100 --> 00:09:57,333 Kevin: Look at that. Ross: Right? 220 00:09:57,400 --> 00:09:58,633 Kevin: So I've got a little amoeba looking thing. 221 00:09:58,700 --> 00:10:00,266 Ross: Right, somewhere here? Kevin: Yeah, right there. 222 00:10:00,333 --> 00:10:03,233 Bluish, whereas around it's kind of a gray or red. 223 00:10:03,300 --> 00:10:04,900 Ross: That's right. Kevin: That's an indication of 224 00:10:04,966 --> 00:10:06,400 water because there's the different temperature? 225 00:10:06,466 --> 00:10:07,900 Ross: That's right. So if I was scanning that, 226 00:10:07,966 --> 00:10:09,700 I'd be like, "Alright, I don't know if it's necessarily water. 227 00:10:09,766 --> 00:10:11,966 I know that there's something going on in this area." 228 00:10:12,033 --> 00:10:14,533 It might be a lack of insulation on a cold day with cold air 229 00:10:14,600 --> 00:10:15,966 infiltrating through or it could be water. 230 00:10:16,033 --> 00:10:18,466 Kevin: Okay. So this might be the first indication. 231 00:10:18,533 --> 00:10:19,833 Ross: That's right. Kevin: How do you confirm? 232 00:10:19,900 --> 00:10:22,566 Ross: Yep. First pass. Alright. Second pass is we can use 233 00:10:22,633 --> 00:10:25,533 one of these, which has an electromagnetic sensor. 234 00:10:25,600 --> 00:10:27,233 Kevin: So this is a water meter? Moisture meter? 235 00:10:27,300 --> 00:10:28,766 Ross: Moisture meter. Exactly right. 236 00:10:28,833 --> 00:10:30,100 It will sense up to three quarters 237 00:10:30,166 --> 00:10:31,733 of an inch into the wall. Kevin: Okay. 238 00:10:31,800 --> 00:10:34,366 Ross: It will work with all building materials, right? 239 00:10:34,433 --> 00:10:36,700 So it can work with concrete, masonry, drywall, 240 00:10:36,766 --> 00:10:38,300 and it's going to give us more targeted. 241 00:10:38,366 --> 00:10:39,833 It's going to tell us where that moisture is. 242 00:10:39,900 --> 00:10:41,366 And it does it nondestructively, meaning 243 00:10:41,433 --> 00:10:44,500 so I can scan and I can see 6%, 8% 244 00:10:44,566 --> 00:10:46,700 and then all of a sudden look at that, right? 245 00:10:46,766 --> 00:10:49,066 Kevin: Oh, yeah. Ross: So I've got problems... 246 00:10:49,133 --> 00:10:50,366 Kevin: Right there. Ross: ...right here. 247 00:10:50,433 --> 00:10:52,000 Kevin: That lines up with the little amoeba I saw. 248 00:10:52,066 --> 00:10:53,000 Ross: That's right. So it's telling me 249 00:10:53,066 --> 00:10:54,233 percentage of moisture. 250 00:10:54,300 --> 00:10:56,133 And, you know, really what we're trying to do 251 00:10:56,200 --> 00:10:59,300 is make sure that stuff stays in that 6% to 9% range. 252 00:10:59,366 --> 00:11:00,766 Kevin: That's a good range? Ross: That's a good range, 253 00:11:00,833 --> 00:11:03,066 but I'm seeing, you know, 15, 18, 20. 254 00:11:03,133 --> 00:11:04,700 Right? So this is going to tell us 255 00:11:04,766 --> 00:11:07,066 really more pointed and indicate it is water. 256 00:11:07,133 --> 00:11:09,000 Kevin: Okay. So that's a good device to have. 257 00:11:09,066 --> 00:11:10,333 The others? Ross: We can go a step further 258 00:11:10,400 --> 00:11:12,500 and go pinned. So, this is destructive, 259 00:11:12,566 --> 00:11:14,800 meaning that I actually have to pin the wall 260 00:11:14,866 --> 00:11:17,266 to actually get the moisture reading and it's going 261 00:11:17,333 --> 00:11:19,800 to send electricity current across the pins. 262 00:11:19,866 --> 00:11:22,700 And obviously more water on the wall means less resistance. 263 00:11:22,766 --> 00:11:25,066 So it means that I have more water content in that wall, 264 00:11:25,133 --> 00:11:26,533 so much more accurate, 265 00:11:26,600 --> 00:11:28,666 but it's not going to work for concrete, masonry, 266 00:11:28,733 --> 00:11:30,066 and other types of materials. 267 00:11:30,133 --> 00:11:32,000 It will work for drywall and wood, of course. 268 00:11:32,066 --> 00:11:34,933 Kevin: Right. I've seen the wood flooring guys use this 269 00:11:35,000 --> 00:11:36,866 and they stick it into the back of their samples or whatever. 270 00:11:36,933 --> 00:11:39,300 So no problem putting little pinholes in this wall. 271 00:11:39,366 --> 00:11:40,766 Will you give us a reading and...? 272 00:11:40,833 --> 00:11:42,366 Ross: Sure. Kevin: Put it -- Yeah. Go down. 273 00:11:42,433 --> 00:11:43,466 That's good. Right there. Ross: Right there? 274 00:11:43,533 --> 00:11:44,933 Kevin: Yeah. Thereabouts. 275 00:11:45,000 --> 00:11:46,200 Ross: Yeah. -[ Meter beeps ] 276 00:11:46,266 --> 00:11:47,400 Kevin: Yeah. Ross: There you are. 277 00:11:47,466 --> 00:11:50,500 Kevin: What do you got? Ross: 16. 18. Yeah. 278 00:11:50,566 --> 00:11:53,166 Kevin: Now, can you come up about two or three inches? 279 00:11:53,233 --> 00:11:54,900 A little higher. A little higher. A little left. 280 00:11:54,966 --> 00:11:56,300 Right there. Ross: Right there? 281 00:11:56,366 --> 00:11:58,533 30. 30. We're off the charts. 282 00:11:58,600 --> 00:12:00,200 Kevin: Corresponds to the amoeba again like that. 283 00:12:00,266 --> 00:12:01,866 Ross: That's right. Kevin: Very cool. So this is -- 284 00:12:01,933 --> 00:12:03,833 Are you saying this is more accurate than this? 285 00:12:03,900 --> 00:12:05,400 Ross: It is. It's going to be very localized 286 00:12:05,466 --> 00:12:08,166 to where those pins are. Kevin: Gotcha. Okay. 287 00:12:08,233 --> 00:12:09,466 Ross: There is a combo meter. 288 00:12:09,533 --> 00:12:11,000 So this has got both. Kevin: Oh! 289 00:12:11,066 --> 00:12:12,766 Ross: So it's got an electromagnetic sensor here 290 00:12:12,833 --> 00:12:14,666 and it's got the pins. Kevin: Sneaky. 291 00:12:14,733 --> 00:12:16,800 Ross: Right? So two for one. I got a two for one with that. 292 00:12:16,866 --> 00:12:18,733 But it's only going to give us the relative scale. 293 00:12:18,800 --> 00:12:20,533 It's not going to give us percent moisture content. 294 00:12:20,600 --> 00:12:22,566 It just tells us dry or wet on a sliding scale. 295 00:12:22,633 --> 00:12:24,400 Kevin: Oh, gotcha. Can you get a combo 296 00:12:24,466 --> 00:12:25,866 that gives you a perc-- Ross: More expensive. 297 00:12:25,933 --> 00:12:28,400 Kevin: More -- You can. Gotcha. I can't say it, but there it is. 298 00:12:28,466 --> 00:12:30,866 Ross: Yeah. There you go. Kevin: So if 6 to 9 299 00:12:30,933 --> 00:12:32,400 is a good reading -- Ross: That's ideal. 300 00:12:32,466 --> 00:12:33,566 Kevin: Ideal? Ross: Yeah. 301 00:12:33,633 --> 00:12:34,833 Kevin: What happens as we go up the scale 302 00:12:34,900 --> 00:12:36,166 and when are we in trouble? Ross: Right. 303 00:12:36,233 --> 00:12:38,933 So once you get to 15, we're starting to get worried. 304 00:12:39,000 --> 00:12:41,433 Once you go beyond 15, we start to get really worried. 305 00:12:41,500 --> 00:12:42,933 Kevin: And what are we worried about? 306 00:12:43,000 --> 00:12:44,833 Ross: We're worried about mold. We're worried about wood rot. 307 00:12:44,900 --> 00:12:45,900 We're worried about structural damage. 308 00:12:45,966 --> 00:12:47,066 We're worried about a lot of things. 309 00:12:47,133 --> 00:12:48,400 Kevin: Gotcha. Ross: Right? So in a perfect 310 00:12:48,466 --> 00:12:49,833 world, everything would be between 6% and 9% 311 00:12:49,900 --> 00:12:53,233 for all building materials and for a normal indoor space. 312 00:12:53,300 --> 00:12:55,900 Kevin: If I get 20%, 30%, what am I doing? 313 00:12:55,966 --> 00:12:58,100 Am I tearing things out? Am I blowing it dry? 314 00:12:58,166 --> 00:13:00,000 Ross: Yeah. When you get that much moisture, you know, 315 00:13:00,066 --> 00:13:01,733 more than 20, you definitely need to replace 316 00:13:01,800 --> 00:13:02,933 the Sheetrock in this example. Kevin: Yeah. 317 00:13:03,000 --> 00:13:04,466 Ross: So you'd be cutting out that section, 318 00:13:04,533 --> 00:13:06,200 removing it, making sure -- inspection -- 319 00:13:06,266 --> 00:13:09,000 to make sure there's no other mold or anything behind there. 320 00:13:09,066 --> 00:13:11,266 Usually we take a larger section than where we see the water 321 00:13:11,333 --> 00:13:13,433 because the water will migrate. Right? 322 00:13:13,500 --> 00:13:16,000 So that's -- If you have a little bit of moisture, 323 00:13:16,066 --> 00:13:17,466 then you can run maybe some dehumidifiers 324 00:13:17,533 --> 00:13:18,766 and just dry out the space to help. 325 00:13:18,833 --> 00:13:21,100 Kevin: Cool. Alright. So I know this is expensive. 326 00:13:21,166 --> 00:13:23,200 Most homeowners aren't going to be playing with this one. 327 00:13:23,266 --> 00:13:25,333 You guys are. But these right here, 328 00:13:25,400 --> 00:13:27,166 they look like I can find them down at the store. 329 00:13:27,233 --> 00:13:28,833 Ross: That's right. Kevin: Sense a price for them? 330 00:13:28,900 --> 00:13:30,233 Ross: Yeah. All less than $100 for all of them. 331 00:13:30,300 --> 00:13:32,100 Kevin: Oh, nice. Very cool. Ross: Yeah. Yeah. 332 00:13:32,166 --> 00:13:33,633 Kevin: Which is good peace of mind if you're trying to find 333 00:13:33,700 --> 00:13:35,033 something you can't see. Ross: That's exactly right. 334 00:13:35,100 --> 00:13:36,100 Kevin: Awesome. Ross: You got it. 335 00:13:36,166 --> 00:13:37,433 Kevin: Thank you, Ross. Ross: Cool. 336 00:13:37,500 --> 00:13:38,833 Kevin: Alright, cool. Ross: Which one do you think? 337 00:13:38,900 --> 00:13:44,466 ♪♪ 338 00:13:44,533 --> 00:13:46,400 Mark: Scott. Scott: Mark, nice to see you. 339 00:13:46,466 --> 00:13:47,533 Mark: You as well. How you doing? 340 00:13:47,600 --> 00:13:48,933 Scott: So, Mark, I wrote in to the show 341 00:13:49,000 --> 00:13:51,033 about these stairs over here, these concrete stairs. 342 00:13:51,100 --> 00:13:53,533 Mark: Okay. Scott: I have two young children 343 00:13:53,600 --> 00:13:55,200 and I have grandparents that are coming over 344 00:13:55,266 --> 00:13:56,833 all the time to watch them. 345 00:13:56,900 --> 00:14:00,233 They run onto the back yard. We just have a safety concern. 346 00:14:00,300 --> 00:14:01,666 Mark: Alright. Scott: It seems a little steep. 347 00:14:01,733 --> 00:14:04,166 We're wondering if we could get some sort of railing in here. 348 00:14:04,233 --> 00:14:06,300 Mark: Alright. So I just took a measurement. 349 00:14:06,366 --> 00:14:08,200 We're actually well within the code. 350 00:14:08,266 --> 00:14:09,966 So you really don't need a railing. 351 00:14:10,033 --> 00:14:11,766 But I do love the idea. 352 00:14:11,833 --> 00:14:14,466 Parents getting older, kids running around. 353 00:14:14,533 --> 00:14:15,933 Safety is always paramount. 354 00:14:16,000 --> 00:14:19,433 So even looking at these steps, they're super solid. 355 00:14:19,500 --> 00:14:21,266 So they'll really accept the installation 356 00:14:21,333 --> 00:14:22,933 of the railings perfectly. 357 00:14:23,000 --> 00:14:24,300 So did you have a design in mind? 358 00:14:24,366 --> 00:14:25,333 Scott: We actually have some stuff over here. 359 00:14:25,400 --> 00:14:26,200 Mark: Alright. Let's check it out. 360 00:14:26,266 --> 00:14:27,933 Scott: Take a look. 361 00:14:29,633 --> 00:14:31,433 Yeah. So we really like these guardrails. 362 00:14:31,500 --> 00:14:33,466 We'd really like something to match up with that. 363 00:14:33,533 --> 00:14:36,033 Mark: That's a great idea.
