Weatherstrip Tape That Actually Seals Drafty Doors
Spent two winters feeling cold air pour in around my front door even though it looked closed tight. These tapes finally killed the draft and stayed put through temperature swings.
Grab this for older wooden doors with uneven gaps. My 1960s door frame had warps everywhere, and this rubber seal compressed right into them. Haven't felt a breeze since October.
Frost King, Silicone Tear Drop Self-Stick Weatherseal
Stick this along the sides of your door frame if you can literally see daylight through the cracks. Took me ten minutes to apply and the difference was instant. Great for renters who can't drill anything.
M-D Building Products 3525 M-D 0 V-Flex Weather-Strip
Use this one if you've tried thinner tapes and they keep peeling off. It's thicker than most and survived a full Minnesota winter on my back door without curling at the edges.
Customer reviews for Duck Brand Heavy-Duty Rubber .38
Perfect for anyone dealing with both drafts and noise. My neighbor's dog barks at 6 AM and this cut the sound noticeably while also blocking cold air. Two problems, one strip.
Frost King EPDM Rubber Self-Stick Weatherseal Tape
Try this on windows you never open during winter. Shrink-wrapped three bedroom windows and my space heater stopped running nonstop. Pays for itself in about a week of heating savings.
3M Indoor Patio Door Window Insulator Kit, Fits 6'8" x 9'
Keep this around for weird gaps that tape won't cover. Pressed it into the cracks around my garage door frame and it sealed spots I'd been ignoring for years. Peels off clean in spring.
Frost King F4 Mortite Caulking Cord 9-1/2-ounce 45-Feet
Door Sweeps and Bottom Seals for Under-Door Gaps
The gap under my front door was big enough to slide a credit card through. That's where half the cold air was sneaking in, and towels were not cutting it.
Swap out your old door sweep for this if you can see light under your door. Slides right onto the bottom edge without screws. Took maybe five minutes and the floor near my door isn't freezing anymore.
Frost King® Thermoplastic Slide-on Door Bottom
Perfect if you rent and can't modify the door. It cinches onto the bottom without adhesive or drilling. Pulled it off when I moved and left zero marks. Landlord never knew.
M-D Building Products M-D Cinch Door Bottom Seal
Toss this under your bedroom door if you keep the hallway cooler than your room. It's basically a foam strip that slides with the door. My bedroom stays five degrees warmer at night now.
Suptikes Door Draft Stopper Under Door Seals for Exterior
Get this for exterior doors that face the wind. Three layers of foam block way more air than a single sweep. My front door faces north and this was the only thing that stopped the whistling sound.
Frost King DS2 Designer Cloth Draft Seal, 36-Inches
For anyone tired of repositioning a rolled-up towel every time they open the door. This clips to both sides and moves with it. Honestly wish I'd bought it three years ago instead of fighting with blankets.
Holikme Two-Sided Door Draft Stopper Weather Stripping
Use this if your current sweep is shredded. The aluminum backing is sturdy enough to survive pets and foot traffic. Screwed it on myself and it's still going strong after two heating seasons.
M-D Building Products 68247 36 in. Silver Aluminum
Window Insulation for Rooms That Never Warm Up
My home office stayed cold no matter what I did with the thermostat. Turned out the single-pane windows were basically open holes. These made the room usable again.
Wrap this over single-pane windows and you'll feel the difference within an hour. My office went from needing a space heater all day to being comfortable with just the central heat.
Duck Max Strength Window Insulation Film Kit
Try this before you spend thousands on replacement windows. Covered four windows in my living room and guests stopped asking why it was so cold in there. Hair dryer shrinks it tight in seconds.
Frost King, Indoor Window Insulation Kit, 42 in. x 62
Press this into the edges where your window meets the frame. It peels off in spring without taking paint with it. Found it after I ruined a window frame with permanent caulk. Learn from my mistake.
Frost King Removable Weatherstrip Caulk RWS5, 5 Ounces
Keep a roll of this on hand because regular tape won't hold film through temperature changes. This stuff stays sticky even when it's freezing. Used the same roll for two seasons of window film installs.
Duck Brand Clear Double-Sided Indoor Window Kit Tape
Great for bedrooms where you don't want foggy or opaque film blocking your view. It's clear enough that you barely notice it's there, but you definitely notice the room is warmer.
Frost King, Plastic Weatherseal Tape, 2in x 100ft, Clear
Snag this if you need to do multiple rooms at once. Comes with enough film for five windows and the tape is included. Did my whole upstairs in one Saturday afternoon before Thanksgiving.
3M, Window Insulation Kit, 3 x 5 in Clear
Foam Tape and Gap Fillers for Sneaky Air Leaks
After I sealed the obvious spots, I held a candle near outlets and baseboards. The flame flickered like crazy. These fixed the leaks I couldn't even see.
Stick this around attic hatches, basement doors, anywhere you feel a draft but can't find the crack. Found three spots in my basement where cold air was pouring in. Total cost was under five bucks.
Frost King Weatherstrip Tape, Self-Adhesive Foam Rubber
Spray this into the gaps around pipes and wires where they enter your house. My kitchen was always colder near the sink, and it turned out there was a quarter-inch gap around the plumbing. Gone now.
GREAT STUFF Big Gap Filler, 12 Oz
Use this on windows that rattle when the wind blows. Cut it to size and press it along the sash. Stopped the rattling and the draft at the same time. My bedroom is finally quiet during storms.
Duck Brand Door and Window Gap Foam Weatherstrip Seal
For anyone with cracks between the trim and the wall near exterior doors. Squeezed a bead along the edges and painted over it. Looks clean and the draft from that corner is completely gone.
Customer reviews for DAP Dynaflex 230 Premium Indoor
Don't just leave your window AC unit sitting there all winter leaking cold air. Wrap this around the edges if you can't remove it. Sealed mine up in November and my electric bill dropped noticeably the next month.
Frost King A/C Safe Air Conditioning Weatherstrip Foam
Pop off your outlet covers on exterior walls and slip these behind them. Sounds crazy but I could feel cold air coming through my living room outlets. Five minutes and a screwdriver fixed a draft I'd blamed on the windows for years.

Tools and Extras That Make Weatherproofing Way Easier
First time I tried weatherstripping I used kitchen scissors and masking tape. It looked terrible and lasted two weeks. Having the right tools makes the whole job faster and cleaner.
Cut weatherstrip tape cleanly instead of hacking at it with scissors. Ragged edges peel up within a week. A sharp blade gives you a tight seal that actually lasts. Learned that lesson the expensive way.
Stanley FatMax Retractable Utility Knife
Measure your door frames before you cut anything. I wasted an entire roll of foam tape by eyeballing it and cutting too short. A tape measure costs less than replacing materials you botched.
Stanley PowerLock 25 ft. L X 1 in. W Engineer's Tape
Keep this around for weatherstrip pieces that start lifting in high-traffic areas. A small piece behind the edge holds everything back down. Saved me from reapplying an entire door's worth of seal last January.
Gorilla, Mounting Tape, Heavy Duty, 60" Black Weatherproof
Use this to hold film in place while you position it on windows. Trying to do it freehand is a two-person job, but masking tape turns it into a solo project. Peels right off after.
Duck Brand General Purpose Masking Tape, 0.94 in. x 55
For renters who need to attach insulation film without leaving residue on painted frames. Tested it on my apartment's white trim and it came off perfectly clean when I moved out. No deposit drama.
Mavalus Mavalus Removable Poster Tape With 1 inch
Grab a decent caulk gun if you're sealing more than one crack. The cheap ones drip everywhere and leave a mess. This one stops flowing the second you release the trigger. My baseboards actually look professional now.
