Been there myself—thought I had everything sealed tight until I realized the dryer vent was basically an open invitation for cold air. If you're still chasing drafts, try this: grab an incense stick or candle and slowly move it around suspect areas on a breezy day. Watch the smoke—it'll show you exactly where air's sneaking in. Worked wonders for me, and honestly, it's kinda fun playing detective around the house...
Had a similar issue with my fireplace—thought it was sealed, but nope, cold air pouring in. Did the candle trick too, and ended up adding some insulation around the flue. Made a huge difference, might wanna check yours if you've got one.
Good call on checking the fireplace flue—it's surprising how much heat loss can happen there. Windows can be just as sneaky, especially at higher altitudes or in colder climates. Even high-quality double-pane windows can struggle if they're not properly sealed or insulated around the frame. I've seen plenty of cases where homeowners invest in top-tier windows but overlook the installation details, leaving gaps that let cold air seep in.
If you're noticing drafts around your windows, try the candle trick there too—just slowly move a lit candle around the edges and watch for flickering. If you spot airflow, you might need to reseal with a quality silicone caulk or even consider low-expansion foam insulation if the gaps are larger. Also, don't underestimate the value of insulated window coverings or thermal curtains; they can make a noticeable difference in comfort and energy efficiency.
It's always worth double-checking these small details before jumping into more expensive solutions like full replacements.
Good tips here, especially about sealing around the frames. I learned this the hard way after spending a small fortune on triple-pane windows thinking they'd solve all my draft issues. Turns out, the installers rushed the job and left tiny gaps around the edges—barely noticeable, but enough to feel a chill when temps dropped below freezing.
I ended up using low-expansion foam insulation (carefully!) around the worst spots and silicone caulk for smaller gaps. Made a huge difference almost immediately. Also seconding thermal curtains; I was skeptical at first, but they genuinely help keep rooms warmer overnight.
One other thing worth mentioning: window film kits. They're inexpensive and surprisingly effective as a temporary fix during colder months. Not the prettiest solution, but if you're dealing with serious drafts and can't tackle a full reseal right away, they're a lifesaver.
Good call on the foam and caulk—a lot of folks underestimate those tiny gaps. I'd also add to watch out for the window sills outside. If they're not sloped properly, water pools, freezes, and messes up your seal...ask me how I know, lol.
