Could be frame issues, yeah... but have you checked the drainage holes at the bottom of the window? Had a similar issue once—rain kept sneaking in, drove me nuts. Turns out those tiny weep holes were clogged with dirt and paint. Cleared them out and problem solved. Maybe worth a quick peek before diving into bigger fixes?

Good call on the drainage holes—I overlooked those myself once and felt pretty silly after spending hours messing with caulk. 😂

Couple other quick things you might wanna check before going full DIY mode:

- Weather stripping: If it's old or cracked, replacing it can make a surprising difference in keeping water (and drafts!) out.
- Caulking: Quick and cheap fix, but make sure you're using exterior-grade silicone. Learned that the hard way when my indoor caulk turned into a crumbly mess after one rainy season...
- Window alignment: Sometimes windows shift slightly over time, leaving tiny gaps. A quick adjustment can help seal things up tighter.

Also, if you're into energy efficiency (like me), sealing up these little leaks can really help cut down your heating/cooling bills. Win-win, right?

Anyway, hope you get it sorted without too much hassle. Let us know how it goes!

"Window alignment: Sometimes windows shift slightly over time, leaving tiny gaps."

Hadn't even thought about alignment... I spent ages redoing weather stripping only to realize the window itself was slightly off. Ever tried adjusting alignment yourself—is it tricky, or am I just clumsy?

Yeah, alignment can be a sneaky issue—I ran into that myself last summer. Thought it was just worn-out stripping at first, but nope, window was slightly off-kilter. Adjusting alignment isn't rocket science, but it does take a bit of patience and finesse. If you're dealing with vinyl or aluminum windows, usually there are adjustment screws hidden under little plastic covers on the sides or corners. Wood windows can be trickier—you might need to shim or tweak the hinges a bit.

Honestly, the first time I tried adjusting mine, I spent half an hour just figuring out where the adjustment points were hidden... felt kinda silly afterward. It's definitely doable though; just take your time and make small adjustments, checking as you go. And keep in mind—sometimes it's not just alignment but also settling of the house itself causing these tiny shifts. If that's the case, don't stress too much about perfection—just aim for snug enough to keep out drafts and moisture.

Good points overall, but honestly, alignment tweaks didn't do much for me. Turned out the flashing above the window was installed wrong—water was sneaking behind the siding. Might wanna double-check that before spending too much time fiddling with adjustments.

Had something similar happen at my place last spring. Thought it was just old caulking, spent a weekend redoing it all, and still had water coming in. Eventually found out the flashing was bent weirdly and letting rain slip behind. Once we fixed that, problem solved. Might be worth checking yours too before you go crazy with caulk or weather stripping...

Yeah, flashing issues are way more common than people realize. I've seen homeowners spend hours redoing caulk or weather stripping, only to find out later it was the flashing all along. Caulk's great for minor gaps, but if water's sneaking behind siding, it's usually something structural like flashing or house wrap. Definitely worth checking that first—could save you a ton of hassle down the road.

Good points, flashing's definitely overlooked. But before jumping straight to structural stuff, I'd ask—have you checked the window itself? I've seen cases where the window frame or even the glass seal was the culprit. Had a client once who replaced flashing and siding only to realize later it was a faulty window seal all along... Talk about frustrating. Might be worth ruling that out first.

Yikes, that sounds like a nightmare scenario. But before we jump to blaming the window itself, a couple things come to mind:

- Even if the window seal or frame seems fine visually, water can still sneak through tiny gaps in caulking or weather stripping. I've been fooled more than once thinking the window was shot when it just needed fresh caulk.
- Weather stripping is often underestimated. People assume it's just for drafts, but I've seen plenty of leaks stopped dead just by replacing worn-out strips.
- Also worth double-checking your drainage around the window. Is there proper slope on exterior sills or ledges? If water pools anywhere near the frame, even a good window seal might struggle.

Not saying window seals aren't sometimes to blame (they definitely can be), but I'd personally start with the simplest fixes first. Last year I helped a friend who was convinced his windows were faulty—after some careful re-caulking and new weather stripping, he hasn't had a leak since. Saved him from prematurely replacing perfectly good windows.

Just my two cents...

Had a similar issue a couple years back—spent ages re-caulking and fiddling with weather stripping, convinced it was something simple. Turned out the window itself had a hairline crack in the frame, barely noticeable. Felt pretty silly after all that effort, haha. Definitely worth checking everything closely before diving into bigger repairs...sometimes the culprit is hiding in plain sight.
