When the inspector thinks your house is older than it is

At this point, I just keep a stash of patch material handy and hope for the best. Sometimes feels like you’re just slowing them down rather than keeping them out for good.

Totally get that feeling - squirrels are relentless. Ever tried using that expanding foam along with mesh? I’ve seen mixed results, but sometimes it seems to freak them out enough to move on. About the inspectors, do you think they ever actually check the dates on wiring or pipes, or is it just a “looks old, must be old” kind of thing? Seems like a lot of guesswork sometimes.

I’ve watched inspectors poke around and honestly, half the time it seems like they’re just eyeballing stuff. One guy told me my “ancient” wiring was from the 80s - turns out it was replaced in 2005. I guess if it looks crusty, it’s old in their book. As for squirrels, mesh plus foam worked until they found a new spot... persistent little monsters.

Had a similar thing happen - my inspector flagged my HVAC as “probably original,” but I had the receipts from 2012. Guess the dust fooled him. As for squirrels, I swear they have a blueprint of my attic. Ended up using steel wool and hardware cloth... foam just got chewed up.

I get the whole hardware cloth thing, but honestly, I’m not convinced it’s the only way to go. We had a squirrel problem too, and after patching with steel wool and mesh, they still found new spots to chew through. Ended up calling a wildlife removal guy who sealed up every gap with metal flashing - no issues since. Sometimes DIY just doesn’t cut it, especially with those relentless little pests.

Interesting you mention metal flashing - did the wildlife guy use it just around the obvious entry points, or did he go over the whole foundation line? I’ve seen some older homes where critters find their way in through spots you’d never expect, especially if the siding’s been replaced a few times. Wondering if anyone’s had luck with different materials, or is it really just about finding every last gap?

I’ve always wondered if it’s even possible to find every last gap, especially in houses that have had a few “updates” over the years. Metal flashing seems solid, but I’ve seen squirrels chew right through aluminum in my neighbor’s place - no joke. Has anyone tried using that heavy-duty mesh or even concrete board in tricky spots? Or is it just a losing battle if the critters are determined enough? Sometimes I think they’re smarter than the inspectors...

I’ve been down this road with a 1950s place that’s had more “updates” than I can count. Here’s what worked for me: First, I went around with a flashlight at dusk, inside and out, looking for any light peeking through. Then I stuffed steel wool in the smaller gaps and used hardware cloth (the 1/4” stuff) for bigger holes - stapled it tight and sealed edges with caulk. Squirrels haven’t gotten through that yet, but they did chew right through some old aluminum flashing before. Concrete board is overkill unless you’re desperate, but I get the temptation. Honestly, you’ll never find every gap, but you can make it tough enough that most critters give up and move on to easier pickings.

Squirrels haven’t gotten through that yet, but they did chew right through some old aluminum flashing before. Concrete board is overkill unless you’re desperate, but I get the temptation.

That flashlight trick is genius - never thought to do it at dusk, but it makes so much sense. I totally get the “you’ll never find every gap” thing. My place is only from the 70s, but I swear it’s got more holes than Swiss cheese. It’s weirdly comforting to know I’m not the only one fighting off determined squirrels.

That flashlight trick is a lifesaver, especially in older places where you just know there’s a hidden gap somewhere. I’ve tried it at dusk and was honestly shocked by how many little pinholes of light showed up along the soffits and around the crawlspace vents. It’s like the house is daring critters to find their way in.

Funny thing - one of my tenants swore up and down that squirrels were getting in through the attic, but after sealing what felt like every possible entry, they still heard scratching. Turned out, the little guys had chewed right through a plastic vent cover behind some bushes. Never would’ve found it without crawling around with a flashlight and a lot of patience.

I get what you mean about concrete board feeling like overkill. I’ve used hardware cloth in a few spots, and it’s held up better than flashing, but nothing’s totally squirrel-proof. Sometimes I wonder if these houses just settle in weird ways over the years, making new gaps as they go. Makes you appreciate the stubbornness of both the squirrels and the folks trying to keep them out.

I’m starting to think my house is basically a squirrel amusement park. I did the flashlight thing too, and honestly was not ready for just how many tiny gaps there were - like, where do they even come from? My place isn’t that old (built in 2001), but it’s settled enough to make me wonder if the inspector was off by a few decades.

I tried hardware cloth over the vents after finding chewed plastic bits all over the yard. It’s holding up, but I swear these critters treat it like a personal challenge. I get what you’re saying about concrete board - seems like a lot, but after seeing what they can chew through, I’m tempted.

Funny thing is, every time I patch one spot, another shows up somewhere else. Maybe it’s just the way these houses shift over time, or maybe squirrels have a sixth sense for weak spots. Either way, I’ve learned to keep a flashlight and a roll of mesh handy... and to never underestimate a determined rodent.

That’s wild how determined squirrels can be. I’ve seen them chew through stuff I’d never expect - PVC, thin aluminum, even some of the cheaper soffit panels. Hardware cloth is usually my go-to for vents and small gaps, but you’re right, they seem to treat it like an obstacle course. Concrete board is a bit overkill for most spots, but if you’ve got a repeat offender area, it might be worth the hassle.

One thing I’ve noticed on newer builds (like early 2000s) is that settling can pull trim away from the framing just enough to make those tiny entry points. Sometimes it’s not even visible until you shine a light at just the right angle. If you haven’t already, check where rooflines meet walls or around dormers - those transitions are notorious for shifting and opening up over time.

I’ve started using expanding foam in combo with mesh for awkward gaps. It’s not perfect, but it slows them down. Still, nothing really stops a squirrel with enough motivation... except maybe a neighbor’s bird feeder that’s easier to raid.

I had a similar issue after we put in our green roof. The inspector actually thought our place was built in the 80s, not 2006, just because a couple of squirrels managed to chew through the fascia and left some pretty ugly marks. Turns out, the combo of settling and the extra moisture from the roof plants made a few trim boards pull away, just enough for critters to squeeze in. We ended up using a mix of stainless mesh and mineral wool, which held up better than foam for us. It’s wild how a tiny gap can change the whole look of a house - or at least how old it seems.

That’s a classic case of “small gap, big headache.” I’ve seen inspectors get tripped up by stuff like that more than once - especially when critters get involved. Squirrels are relentless, and once they find an entry point, it’s game over for trim boards. Stainless mesh is a solid choice, way more durable than foam in the long run, especially with all that extra moisture from a green roof. Did you notice any issues with condensation or mold behind the mineral wool? That’s one thing I’ve had to watch for with similar setups, especially if the airflow isn’t great.

It’s wild how quickly exterior details can age a place, even if the bones are new. I’ve had newer properties get flagged for “age” just because of weathered fascia or a couple of warped boards. Sometimes I wonder if inspectors lean too much on first impressions instead of looking at the actual structure. Either way, sounds like you caught it before it turned into a bigger problem.

Yeah, inspectors can be brutal about curb appeal stuff. I had one call out “premature aging” on a three-year-old place just because the paint on the soffit peeled a bit after a wet winter. Drives me nuts. As for condensation, I’ve only had issues when the venting was blocked - usually by, you guessed it, squirrel nests. Stainless mesh is my go-to now. Foam just turns into critter chow around here.

- Inspectors nitpick the weirdest stuff sometimes. Had one flag a “weathered” fence that was only two years old - turns out it just needed a power wash.
- Peeling paint after one wet season is pretty normal here. I’ve stopped using anything but marine-grade on soffits, honestly.
- Stainless mesh is smart. I used foam once and the raccoons shredded it in a week... never again.
- Curious - has anyone actually had luck with those ultrasonic pest repellents in attic vents? Or is that just another gimmick?

Marine-grade paint on soffits is a game changer - totally agree. Regular stuff just flakes off after a few months here, especially with all the rain. I’ve seen inspectors get hung up on the tiniest things too, like a bit of moss on a north-facing shingle. As for those ultrasonic pest gadgets, I tried one in my parents’ attic. Didn’t notice any difference - mice still found their way in. Stainless mesh is the only thing that’s actually worked for us. Foam’s basically raccoon candy around here.

Marine paint on soffits - yeah, I learned that lesson the hard way. Used some “premium exterior” stuff from the hardware store, and it looked great for about six months. Then the rain hit, and it started peeling like a sunburn. Switched to marine-grade after my neighbor clued me in, and haven’t had to touch it since. It’s not cheap, but neither is scraping and repainting every year.

Inspectors, though... I swear, they must have a sixth sense for finding the tiniest patch of moss or a single rusty nail. Last time I had one out, he poked at a spot of lichen on the north side of the roof like it was radioactive. The house is only 12 years old, but he made it sound like it was built during the Eisenhower administration. Sometimes I think they just want to justify their fee.

On the pest front, I’m with you - those ultrasonic things are basically nightlights for rodents. Tried two different brands in the crawlspace and attic. Mice didn’t even pause to sniff. Ended up crawling around with a flashlight and a roll of stainless mesh, stuffing every gap I could find. That actually worked. The foam stuff? Yeah, it’s like a buffet for anything with teeth. Found a chunk of it dragged halfway across the attic once... pretty sure the raccoons were redecorating.

It’s funny how much you end up learning by trial and error. Half the time, what works in theory just doesn’t cut it in real life - especially with this climate. If there’s a shortcut, I haven’t found it yet. At this point, I just assume everything will take twice as long and cost twice as much as I planned. Keeps the surprises to a minimum.

Marine paint on soffits is the only way to go. I’ve managed a handful of properties near the coast and anything less just turns into a maintenance nightmare. People balk at the price, but like you said, repainting every year costs a lot more in the long run. As for inspectors, I get it - they seem to have a radar for the tiniest imperfections. Sometimes I think they’re just trying to justify a longer report. Still, I’d rather they find it than a tenant or buyer down the road.

On pests, stainless mesh is the only thing I trust now. Tried foam, steel wool, even those ultrasonic plugs... rodents just treat it like new furniture. If there’s one shortcut, it’s learning to do things right the first time, even if it takes longer up front. Otherwise, you’re just chasing your tail.

That marine paint advice is reassuring - I've been debating whether to go that route on my own place. The upfront cost made me hesitate, but hearing how much hassle it saves over time makes sense. I guess the alternative is just endless scraping and touch-ups, which sounds exhausting. Did you notice any difference in how it holds up to salt spray or humidity compared to regular exterior paint? I’m in a pretty damp area and worried about mold creeping in.

Totally get what you mean about inspectors too. Mine pointed out things I never would’ve noticed, like a tiny gap behind the gutter that apparently “invites pests.” At first, I was annoyed, but after finding a mouse in the attic last fall, I’m kind of grateful for the nitpicking. Speaking of which, I tried those ultrasonic pest repellents too… they might as well be nightlights for all the good they did. Stainless mesh seems like a solid call - do you just staple it over vents, or is there a trick to getting it snug?

It’s a lot of trial and error, but I’m starting to see the value in not cutting corners. Still, feels like there’s always something new to learn.

Did you notice any difference in how it holds up to salt spray or humidity compared to regular exterior paint? I’m in a pretty damp area and worried about mold creeping in.

You’re not wrong to be cautious about damp - humidity and salt air can really do a number on standard paints. Marine paint’s definitely more resistant to both, but I’ve still seen some mold pop up around shaded areas, especially where airflow’s poor. It’s not a magic bullet, but it does seem to slow down the peeling and bubbling you get with regular exterior stuff. If you’re in a spot that never really dries out, you might want to look into vapor-permeable primers underneath, too.

Stainless mesh is a solid move for pest control. I’ve had better luck using self-tapping screws with washers instead of just stapling - gets the mesh tighter and keeps critters from pushing through the edges. Sometimes a bead of exterior caulk around the frame helps seal up any tiny gaps.

Honestly, I used to think inspectors were just nitpicking, but after patching up one too many “minor” gaps, I’ve come around. There’s always something new to chase down, but it pays off in the long run.
