How do you handle the dirty work: DIY or call in the pros?

Wet sanding’s always messier than it sounds, especially overhead. I’ve had the same issue - drips everywhere, and it’s tough to control. As for “dustless” sanders, they’re decent for small patches, but yeah, the filters clog up fast if you’re doing a whole ceiling or wall. I usually stick with regular sanding and a good shop vac attachment. Less hassle in the long run, even if there’s some dust to clean up after.

- Wet sanding overhead is a nightmare - I've tried it a couple times and ended up with more water on the floor than on the wall.
- Those “dustless” sanders are a bit overhyped in my opinion. Like you said, filters clog up quick, and then you’re just fighting with the machine instead of getting work done.
- I usually just go old-school: sanding block, mask, and a big tarp. Shop vac helps, but there’s always some mess.
- Honestly, unless it’s a huge job or something super visible, I’d rather deal with a little dust than all the hassle of wet sanding or fancy tools.
- Funny thing is, I’ve seen pros make just as much mess as DIYers... sometimes more.

I hear you on the dustless sanders - they sound great until you’re halfway through and the filter’s clogged, then you’re just making a different kind of mess. I tried wet sanding once in my bathroom and honestly, it was more work cleaning up the puddles than the actual sanding. I’ve mostly stuck to the old-school block and mask routine too, but every time I finish, it feels like I’m still finding dust in corners weeks later.

Here’s what I keep wondering: is it really worth calling in a pro for stuff like this? I mean, if they’re just as messy (or worse), what’s the point? Has anyone actually had a pro come in and leave things cleaner than they found them? Or is it just paying for someone else to deal with the headache?

I’ve been down this road more times than I care to admit. First time I tried to “save time” with a dustless sander, it was in a rental between tenants. Thought I was being clever - less cleanup, right? Well, by hour two, the filter was so packed I might as well have been sanding with a leaf blower. There was a fine layer of dust on everything, including me. Tenants moved in and I was still finding dust in the cabinets a month later.

I’ve hired pros a handful of times, mostly when I just didn’t have the bandwidth. Here’s the thing: some of them are genuinely meticulous. I had one crew come in for a popcorn ceiling removal, and they tented off the entire room, ran negative air machines, and vacuumed every surface before they left. I was honestly impressed. But I’ve also had others who basically did what I would’ve done myself, just faster and with more expensive tools. Still had to go back and wipe down baseboards and mop floors.

I guess it comes down to who you hire and how much you’re willing to pay. The really good ones, the ones who treat your place like it’s their own, tend to cost a bit more. But they can save you hours of cleaning up after the fact. If you’re just looking to avoid the headache, it might be worth it. If you’re picky about the end result, you might still find yourself doing a final pass no matter what.

Honestly, I still end up doing a lot of the dirty work myself. At least then I know exactly where the dust is hiding. And I’ve learned to just accept that I’ll be finding drywall dust in weird places for weeks. Comes with the territory, I guess...

That’s pretty much my approach too, especially when I’m trying to keep costs down. I’ve had a few “pro” jobs that were just as messy as if I’d done it myself, except I was out a few hundred bucks and still stuck scrubbing baseboards. Not to mention, some of them seem to rush through just to get to the next gig.

If it’s something like sanding drywall or pulling up old carpet, I’ll usually just block off the area with plastic sheeting and go at it myself. It’s not fun, but at least I know what corners got missed (and let’s be real, there’s always one). The only time I really shell out for pros is when it’s something I can’t realistically do solo - like big electrical or major plumbing.

I will say, investing in a decent shop vac with a HEPA filter was a game changer for me. Still dusty, but it cuts down on the cleanup time a lot. And I’ve learned to just accept that no matter how careful you are, you’ll be finding dust in your socks and light fixtures for weeks. It’s just part of the deal.

The one thing I disagree with a bit is that paying more always gets you better results. Sometimes you’re just paying for a fancy van and some branded shirts. If you do go the pro route, word of mouth from neighbors or friends seems to be the only way to find folks who actually care about doing a thorough job.

At the end of the day, if money’s tight and you don’t mind getting your hands dirty, DIY isn’t so bad. Just gotta set your expectations low on how “dustless” anything involving drywall or sanding will actually be...

- 100% agree with this:

Sometimes you’re just paying for a fancy van and some branded shirts.

- Shop vac with HEPA is a must. Also, swapping out filters often makes a bigger difference than most folks realize.

- For drywall dust, I’ve found damp-wiping surfaces after vacuuming helps catch what the vac misses. Still, you’ll be finding dust for weeks... just how it goes.

- Only exception where I’d say pros are worth it: asbestos or lead paint. Not worth the risk messing with that stuff yourself. Everything else? If you’ve got the patience, DIY usually wins.

I get the appeal of DIY, but I’ve seen a few jobs go sideways when folks underestimated what’s involved - especially with stuff like mold or water damage. It’s not just about patience, sometimes it’s about having the right tools and knowing what you’re looking at. I tried to tackle a moldy basement corner myself once, thinking it was just surface-level. Ended up making it worse and had to call in a pro anyway. Cost me more in the end.

Also, on the HEPA vacs - totally agree they’re key, but I’d add that not all filters are created equal. Some of those “HEPA” labels are pretty generous. Worth checking the specs if you’re serious about air quality.

For drywall dust, I’ve started using microfiber cloths instead of regular rags for damp-wiping. They seem to grab more of the fine stuff, at least in my experience. Still, you’re right... that dust lingers forever.

I’m all for DIY where it makes sense, but sometimes bringing in someone who knows their stuff is worth every penny - especially if you care about minimizing waste and doing things right the first time.

I’m with you on the “know your limits” thing. I’ve had a few moments where I thought, “How hard can it be?” - then realized halfway in that I was out of my depth. Especially with mold or anything that could mess with air quality, I’d rather err on the side of caution. Have you ever tried renting pro-grade equipment for smaller jobs? Sometimes it’s a good middle ground if you’re not ready to hire someone but want to do it right.

Have you ever tried renting pro-grade equipment for smaller jobs? Sometimes it’s a good middle ground if you’re not ready to hire someone but want to do it right.

That’s a smart approach. I rented an industrial dehumidifier once for a basement leak - definitely felt more confident with the right gear. Still, when it comes to mold, I get nervous about missing something hidden. Sometimes peace of mind is worth the extra cost.

Renting pro-grade tools can be a real game changer, especially for those jobs where regular hardware store gear just doesn’t cut it. I’ve done it a few times - carpet cleaner, tile saw, even a heavy-duty shop vac - and it’s usually worth the little extra cost for better results. You get that feeling of “I’m doing this right,” which counts for a lot.

But I know what you mean about mold. That’s where I start to draw the line too. Like you said,

“Still, when it comes to mold, I get nervous about missing something hidden.”

I guess my rule of thumb is: if it’s something visible and contained, and I can research the process thoroughly, I’ll try renting and doing it myself. But if there’s any chance the problem’s bigger than it looks - like water damage that might have spread, or electrical stuff - I’d rather pay for a pro and avoid making a costly mistake. Sometimes spending a bit more upfront is cheaper than fixing a botched job later.

That said, I do think people underestimate how much you can get done with the right equipment and a bit of patience. The key is knowing your limits and not being afraid to admit when you’re out of your depth. There’s no shame in calling in help if it means keeping your home safe and sound.

I hear you on the mold - tried to tackle a small spot in my basement once with a rented air scrubber and some bleach, but it just kept coming back. Ended up needing to rip out drywall and call in a pro anyway. For stuff like painting or tiling, I’m all about renting decent tools and doing it myself, but hidden damage is where I draw the line. Sometimes you just gotta know when to step back and let someone else handle the mess.

Totally get where you’re coming from, but I always wonder - how do you decide when it’s time to call in the cavalry? Like, is it just about the size of the problem, or is it more about what’s hiding behind the walls? Mold’s tricky... did you ever figure out where the moisture was coming from? I see folks bleach the surface and think it’s gone, but that stuff loves to hide. Ever try using a moisture meter before tearing things out, or is that overkill?

Honestly, I’ve seen folks spend hours bleaching and scrubbing, only for the mold to creep back a month later. Moisture meters aren’t overkill if you ask me - they’re actually pretty handy. Sometimes the “mess” is way deeper than you think. I’ve pulled out drywall that looked fine on the outside, but behind it? Total science experiment. Size isn’t always the best indicator... sometimes it’s just about what’s lurking where you can’t see.

I hear you on the moisture meters - those things have saved me a ton of headaches. I used to just patch and paint over spots, thinking I’d nipped it in the bud, but nope... two months later, same issue, sometimes worse. Once I started actually checking behind the walls and under the floors, I realized how sneaky water damage can be. Sometimes it’s worth calling in pros, especially if you’re dealing with anything bigger than a dinner plate or if it smells musty. DIY is fine for small stuff, but hidden mold? That’s a whole different beast.

I hear you on the sneaky water damage. I used to think a little paint and some “positive thinking” would fix it, but nope - turns out water doesn’t care about my optimism. I’m all for DIY when it’s just a small patch or a bit of caulk, but once I caught that musty smell (like gym socks left in a hot car), I knew I was in over my head.

I tried to tackle hidden mold myself once - ripped up a corner of carpet and found what looked like a science experiment gone wrong. Ended up spending more on supplies than if I’d just called someone in the first place. Lesson learned: small leaks, sure, I’ll roll up my sleeves. Anything that makes me gag or requires a hazmat suit? That’s where my wallet comes out.

Moisture meters are great, but sometimes my nose is the best tool I’ve got... If it smells funky, time to call in the cavalry.

That’s basically my approach too - my wallet stays closed unless something really sets off the “uh-oh” alarm. But honestly, I’ve found that the line between “DIY-able” and “call the pros” is pretty fuzzy, especially when you’re trying to keep costs down. Like, I’ve patched drywall and replaced baseboards after a small leak, but as soon as there’s any hint of mold, I don’t mess around. The cost of getting it wrong just isn’t worth it.

Here’s what gets me: some folks swear by just painting over stains or using those mold sprays from the hardware store. But does that actually solve anything long-term? I’m not convinced. Even after reading a ton online, I still wonder where to draw the line. Is there a rule of thumb you use - like square footage, or how bad the smell is - before you decide it’s time to bring in a pro? Or is it just a gut feeling?

Honestly, painting over stains is just putting lipstick on a pig - never seen it hold up long term. I usually use the “bigger than a pizza box” rule: if damage is smaller than that and there’s no musty smell, I’ll tackle it. But once you get that funky odor or the spot keeps coming back, I’m out. Ever tried those mold test kits? I’ve thought about it but not sure if they’re worth the hassle...

I get what you’re saying, but I’ve actually had a few spots where painting over stains (with the right primer, like Kilz or BIN) did the trick for a couple years - no reappearing marks, no issues. Maybe it depends on how deep the stain goes? As for those mold test kits, I tried one once and honestly, it gave me more questions than answers. The results just seemed vague. Ever just cut out the bad section instead of messing around with tests? Sometimes feels quicker.

Cutting out the bad section is usually my go-to, especially if the stain looks like it’s got some depth or there’s a whiff of mustiness. Paint and primer can work wonders for surface stuff, but if you’ve got that classic yellow-brown “mystery” stain creeping back or spreading, there’s probably something funky happening behind the scenes. I’ve seen folks slap on Kilz and call it a day, only to have the same spot bubble up six months later.

Those mold test kits...yeah, mixed bag. Half the time they just tell you “something’s growing,” but not if it’s the dangerous kind or just your average dust bunny. If I’m dealing with drywall and it’s soft or crumbly, I just cut out a chunk (doesn’t have to be pretty), check what’s behind, and patch it up. Way less guesswork. Plus, you get to wield a utility knife, which is always a bonus in my book.

If it’s a small area, DIY is fine. But if you find black mold or the framing’s mushy, that’s when I start thinking about calling in backup. No shame in knowing your limits - sometimes the pros have the right gear for the gnarly stuff.

Cutting out the damaged section is definitely the most thorough way to handle it, especially if you’re concerned about what’s lurking behind the stain. I agree with this:

Paint and primer can work wonders for surface stuff, but if you’ve got that classic yellow-brown “mystery” stain creeping back or spreading, there’s probably something funky happening behind the scenes.

I’d just add that if you’re going to open up a wall, it’s worth taking a moment to check for any signs of leaks or condensation issues. Sometimes the root cause is a slow pipe drip or poor ventilation, and patching without addressing that just sets up a repeat performance.

On the eco side, I try to minimize waste by only removing as much drywall as needed, and I look for low-VOC patching compounds and paints. If you do end up with mold, vinegar or hydrogen peroxide can be effective for small spots, but I’m with you - if it’s black mold or the wood feels soft, it’s time to call someone with the right safety gear. No sense risking your health over a patch job.

And yeah, wielding a utility knife is oddly satisfying... just don’t get too carried away or you’ll be patching more than you planned.
