The Importance of Re-Caulking Your Windows: Keep the Drafts Out
/The Battle Against the Cold (and Your Energy Bill!)
It’s that time of year again—the temperature is dropping, your furnace is working overtime, and somehow, despite being indoors, you’re still feeling the occasional chilly breeze. You start questioning everything: Did I leave a window open? Is my house haunted? (If you hear eerie whispers, that’s another blog entirely.)
More likely, though, you’re experiencing the very real—and very frustrating—phenomenon of failing caulking around your windows. And while ghosts might be scary, the true horror story here is the money slipping out of your home in the form of wasted energy.
Re-caulking is a simple yet incredibly effective way to keep your home warm, your energy bills in check, and your family comfortable all winter long. So let’s dive into why it matters and how you can get started.
Why Re-Caulking Matters: More Than Just a Quick Fix
1. Lock Out the Cold and Keep the Cozy
Picture this: you’re sitting on your couch with a hot cup of tea, wrapped in a blanket, and suddenly, a draft sneaks up your spine like an uninvited guest. That draft? It’s coming from your windows. And no, it’s not the ghost of winters past—it’s old, cracked caulking.
By re-caulking, you can seal those gaps and keep your home snug. Think of it as fortifying your castle against the cold—and winning the battle for comfort.
2. Save Money on Energy Bills (and Spend It on Fun Stuff!)
If your windows aren’t properly sealed, you’re essentially paying to heat the great outdoors. Drafty windows force your heating system to work harder, which means higher energy bills.
Re-caulking can reduce heating and cooling costs by up to 20%. Imagine putting that money toward something more enjoyable—like a weekend getaway or treating yourself to a fancy coffee (or three).
3. Stop Moisture Before It Becomes a Monster
Drafts aren’t the only thing that sneaks through bad caulking. Moisture can creep in, too, leading to rot, mould, and other costly problems.
Unchecked moisture can cause:\n- Warped wood floors\n- Rotting window frames\n- Mould growth (and the sneezing fits that come with it)
Re-caulking your windows acts like an umbrella for your home—keeping the wet out and your wallet safe from expensive repairs.

Signs That It’s Time to Re-Caulk
Wondering whether your windows and doors need a little TLC? Here are some telltale signs that your caulking has seen better days:
Visible cracks or gaps in the caulking
Peeling or crumbling caulking
Drafts near windows or doors
Increased energy bills without explanation
Water stains or condensation forming around window sills
If you’re experiencing any of these issues, it’s time to grab a caulking gun (or call in a pro) and get those gaps sealed up.
Can You Re-Caulk Windows in Winter?
Exterior caulking requires mild temperatures to adhere properly, so if it’s below freezing, it’s best to wait until spring. But don’t despair—you can still caulk your windows from the inside.
Interior caulking is a quick, effective solution to stop drafts and improve comfort during the colder months. Come spring, you can tackle the outside for a complete seal.
DIY vs. Hiring a Pro: Which is Right for You?
Re-caulking is one of those tasks that seems simple… until you’re halfway through and realize your hands are covered in caulk, you’ve accidentally sealed your sock to the floor, and your “clean” line looks like it was done by a toddler with a glue stick.
If you’re up for the challenge, here’s what you’ll need:
Step-by-Step Guide: How to Re-Caulk Your Windows Like a Pro
If you’ve decided to tackle re-caulking your windows yourself, good on you! It’s a manageable project that can make a world of difference. Here’s a step-by-step guide to get the job done right. Plus, if it’s too cold to caulk the exterior right now, don’t worry—sealing the inside can still stop drafts and improve comfort.
Tools and Materials You’ll Need:
High-quality interior caulking (silicone or latex-based is ideal)
Caulking gun
Utility knife or scraper (for removing old caulk)
Rubbing alcohol or caulk remover
Painter’s tape (optional, for clean lines)
Damp cloth or sponge (for smoothing the caulk)
Steady hand and a little patience
Step 1: Remove the Old Caulk
Old, cracked caulk needs to go before you apply the new layer. Use a utility knife or scraper to carefully cut and peel away the old caulk. Be thorough—leftover bits can prevent the new caulk from adhering properly.
Pro Tip: If the old caulk is stubborn, apply a caulk remover product and let it sit for a few minutes to loosen it.
Step 2: Clean the Surface
Wipe down the area with rubbing alcohol or warm soapy water to remove dust, debris, and any remaining caulk residue. A clean surface ensures that the new caulk adheres properly.
Step 3: Prep the Area
For sharp, clean lines, apply painter’s tape along both sides of the area you’ll be caulking. This step is optional but highly recommended if you’re new to caulking or want a professional-looking finish.
Step 4: Cut the Caulking Tube
Insert the caulk tube into the caulking gun, then cut the tip of the tube at a 45-degree angle. Start with a small opening—you can always cut more if you need a wider bead of caulk. Poke a nail or similar tool into the tip to break the inner seal.
Step 5: Apply the Caulk
Hold the caulking gun at a 45-degree angle and apply steady pressure to the trigger. Run the tip smoothly along the seam, laying down an even bead of caulk. Aim for a consistent line—don’t worry if it’s not perfect; you’ll smooth it out in the next step.
Step 6: Smooth the Caulk
Use a damp cloth, sponge, or even your finger to smooth the bead of caulk. This step helps to seal the caulk into the gap and creates a neat finish. If you used painter’s tape, remove it carefully while the caulk is still wet to avoid pulling up the edges.
Step 7: Let It Cure
Most caulks need 24 hours to fully cure. Check the manufacturer’s instructions for exact curing times. During this period, avoid touching or disturbing the caulk.
A Note About Winter Caulking:
If temperatures outside are below freezing, caulking the exterior of your windows isn’t recommended—caulk may not adhere properly in the cold. However, interior caulking is still a great option to stop drafts and improve your home’s comfort. By sealing gaps on the inside, you can block cold air and prevent warm air from escaping. Come spring, you can tackle the exterior to ensure a complete seal.
