Twelve inspections in three days sounds impossible until you hear what a busy building inspector’s week actually looks like and why so many homes are crying out for basic maintenance. We sit down with Evan to unpack a real maintenance report for a Waikanae beachfront property that’s just been inherited by three daughters. The location is incredible, but the exterior tells a harder story: older cedar shiplap cladding that has warped, cupped, and split so badly that some boards break under pressure, plus joinery damage that’s already well past “a bit of paint will sort it”. 

We get practical about what a maintenance report adds compared with a typical builder’s report, especially when the goal is weathertightness. Evan talks through how he documents the problem areas in writing, why that matters when you’re chasing quotes, and how thermal imaging can show where moisture is holding inside the house before the stains and mould shout about it. If you’ve ever wondered whether you can just patch and carry on, this conversation makes the decision points clearer. 

Then we talk money and scope without sugar-coating it: scaffolding, painting, joinery replacement, and the difference between direct fix and a new cavity system, plus how consent and wind zone settings can change the path. We also touch on smaller unit inspections for development work, Healthy Homes compliance, and why delaying maintenance is the fastest way to inflate your future spend. If you know someone who’s bought, inherited, or rents out a property, share this with them, then subscribe and leave a review so more Kiwi homeowners can find it. What’s the first thing you’d want checked on your place?

SPEAKER_00

So I've got Evan back. He's a building inspector. And this week he's been very, very busy. He's he's just told me he's done over twelve inspections this week. Hello, Evan.

SPEAKER_01

Hi, how's it going?

SPEAKER_00

Good. Twelve

Twelve Inspections In Three Days

SPEAKER_00

inspections in one week. That's a lot.

SPEAKER_01

Twelve inspections in three days.

SPEAKER_00

Oh, hold on. In three days. Wow, that's a lot of exercise for you.

SPEAKER_01

Uh-huh. Yep.

SPEAKER_00

Okay, what's the common theme that you're seeing at the moment?

SPEAKER_01

So this week has been mainly focused on maintenance reports. So one of the inspections that I did on Monday, it's for a beachfront property

Inherited Waikanae Beachfront House

SPEAKER_01

in Waikanae. And the vendors passed away and it's getting inherited by the three daughters. And they essentially needed to know what the condition of the house was. They also a valuer came in and valued it quite high. And that's when they got a builder to come through, have a look, and they were like, it's it really needs a reclad, new joinery, a bunch of a bunch of work. But he wasn't willing to put anything in writing because he's not qualified to do so. So that's when they engaged me, went in and pretty much confirmed what the builder said, but really detailed what areas were the problematic issues. So this beachfront property was a cedar clad. So I think we talked about a little bit about last time.

SPEAKER_00

Last time about the cedar, but for those that don't

Cedar Cladding Failures And Risk Areas

SPEAKER_00

haven't listened to that one or don't remember, do you just want to quickly brush over the cedar cladding?

SPEAKER_01

So cedar cladding's great. So this one here was an older style uh cedar cladding, which is shiplap. So instead of like bevel back weatherboards or vertical shiplap, which is pretty common for building products nowadays. This one it has like a flush profile finish. And so when you look up the side of a building, you can literally just see all the bottoms just warping, and you can see gaps up underneath the cladding. When it's not too advanced, you can actually nail those back down and you can seal them. But this one here, I pushed on some and they just split uh and broke. So the northern, eastern, and southern faces were just completely cooked, essentially. The only the only good side was the western face, which is usually one of the more exposed ones, and especially being on a beachfront. However, it had a wraparound veranda deck, so it was completely enclosed with the normal kind of elements. You could see a little bit of weathering and stuff to the bottom edge right next to the deck, but other than that, it was pretty good on the western face.

SPEAKER_00

Wow. Okay, so you gave them a plan. Well, you give them a report.

SPEAKER_01

Yeah.

SPEAKER_00

A maintenance report.

SPEAKER_01

Yeah.

SPEAKER_00

And now they can take that report back to the builders and get quotes. Yeah. And then decide whether they want to fully renovate and sell. Because I guess in that state, it won't really sell it that much.

SPEAKER_01

Because I don't think the intent is to sell for that one. They're they they want to keep the property, whether or not I guess the it was clarity on what would be required if they were to re-clad and you know do all new joinery, or do they bold the house and and build something new on it? Because the location is incredible. Yeah.

SPEAKER_00

Okay. So was those sort of reports like I understand usually the vendors or order them or the buyers, but in this case it's the kids that inherited the house. It's okay for them to order as well.

SPEAKER_01

Yep, 100%.

SPEAKER_00

Okay. I guess they're the new owners? Yeah. I don't know how it was their stake.

SPEAKER_01

I'm not too sure, you know, on the other hand.

SPEAKER_00

But someone can just give you a call and be like, hey, come on over, do the maintenance report.

SPEAKER_01

Yeah.

SPEAKER_00

So how is maintenance report different to the builder's report?

SPEAKER_01

So the way that I write my builders' reports is I do include a lot of the maintenance issues. This one really focused on weather tightness

Weathertightness Scope And Cost Range

SPEAKER_01

and what it's going to entail to get the house back to being weathertight, and you know, when there's cupping holes to the cladding, splits, rotten joinery where you can just poke your finger into it. And then I did thermal imaging on the inside as well, which clearly showed areas where moisture was holding.

SPEAKER_00

That would be an expensive exercise for them.

SPEAKER_01

Yeah, I ballpark figure. He he actually was pretty close to the the money, the husband of one of the daughters. He's he's a Sparky, so he's in the trade. He kind of had a figure of around about 300.

SPEAKER_00

I was about to say 300 to 400.

SPEAKER_01

I said, yeah, it could depending on if you have to go through consent and if you can do the direct fix where the boards again is, I think, zoned to be able to do direct fix. If it was one wind area higher, if it was extra high, then I don't think you're allowed to. Uh, I'd have to double check that. But yeah, putting in a new cavity definitely means you have to replace all the joinery. Yeah. It's a lot of scaffolding and you know, painting and all that jazz. It it could be, you know, anywhere from 250 all the way up to 600k.

SPEAKER_00

That's crazy. You know, it would be really cool to like fast forward us into the future 30 years later, and you put like a little thing onto the house, you press a button, and it automatically just goes and like covers covers the whole house and the cladding. How cool would that be? Yeah, you'd um you'd put a lot of builders out of a job if you well, there you go, guys, for those that aren't in tech and building expertise, you know, think of something that you can just like press a button and it just goes. That's my new um voice effect. Thank you. But awesome. So, how fast can you turn around those reports? Because I mean, if you've done 12 in three days, you'd be like off your feet.

SPEAKER_01

Yeah. So I mean wait. I was I was working until probably like nine

Report Turnarounds And Healthy Homes Work

SPEAKER_01

or ten last night. I sent it out last night. Um, two days. Yeah, 48 hours for that one.

SPEAKER_00

Wow.

SPEAKER_01

If if I wait too long, then all of a sudden it's just a snowball effect. I I really have to keep on top of it, and it's fine. The majority of my inspections this week, they're smaller units, and it's for a it's for a development company. So I've been working with them, uh working with some subtrades to get just generalized estimates and yeah, mainly just focusing on the maintenance side of things if they're healthy homes compliant and what the costs to get it to healthy homes compliant or just the general maintenance.

SPEAKER_00

Do you do the healthy homes sign-offs as well? Yep. You do that.

SPEAKER_01

Yeah. Okay.

SPEAKER_00

Good to know. Yeah. All right. Well, awesome. Thank you so much, Evan, for sharing that story. I think that's quite important for people to remember that you know, whether you buy, whether you inherit something, you can get a check on that

Why A Maintenance Pulse Check Matters

SPEAKER_00

as well. Just a pulse check to see what's the investment like and um what what do you need to put up with. Because you can't just ignore it. Like you've got the house now. You've got to do something about it. Exactly. And the longer you ignore it, the worse it's gonna get. Yep. Awesome. Thank you so much, Evan.

SPEAKER_01

See you soon. Cheers.
