Check for Drafts

You might feel it before you see it – a chilly gust under your door frame, an uncomfortable draft in an otherwise cozy room. Drafty doors are a common issue and they’re not always easy to detect. But don’t worry! There are simple ways to check for drafts and you don’t need a professional to do it.

Here’s how to identify a draft:

Visual Inspection and Hand Test

Sometimes, spotting a draft is as simple as a close scrutiny of your door. Examine the door and its frame closely. Look for visible gaps and worn-out weatherstripping.
Next, conduct a hand test. During a cold day, run your hand along the edges of the door. If you feel a cold breeze seeping in, bingo! You’ve found a draft.

Light Test

The light test can be a big help. Wait until it’s dark outside then turn off all the lights in the room. Ask someone to shine a flashlight on the door from the other side. If you see light coming through, that’s your draft. You can also use this method in daylight by looking for sunlight coming through your door frame.

Smoke Test

The smoke test is a surefire way to find those pesky drafts. Close all windows in your home and turn off any fans. Then, light up a stick of incense and hold it near the door frame. Watch the smoke. If it wavers or blows into the room, you’ve found a draft.

These methods will help you detect drafts in your doors. Once you’ve identified the issue, move to the next step in our simple, DIY guide: Draft Proofing.

Use Weatherstripping

Now that you’ve identified where those pesky drafts are sneaking in, it’s time to move onto the next stage: draft proofing. One of the best ways to tackle this is by using weatherstripping.

Weatherstripping is a material you can use around doors to stop drafts and keep the warmth where it belongs – inside your house.

There are various types of weatherstripping available, each with its range of benefits and installation methods. Below are a few of the well-known types:

  • V-strip or tension seal: A durable, plastic strip that works well for the sides and tops of doors.
  • Door sweep: Attached to the bottom of the door, this product blocks gaps and prevents drafts from creeping in.
  • Tape or adhesive-backed: This form of weatherstripping is great for irregular or awkward shaped doors where other types may not serve best.

Once you’ve chosen your preferred type of weatherstripping, the next step is installation. Remember, the aim here is ensuring a snug fit between your door and its frame, acting as a seam against the draft.

Start by measuring the door or window you’ll be applying the weatherstripping to. You’ll need these dimensions when you’re buying your weatherstripping, so don’t guesstimate or you could end up with the wrong size. Once you have the correct size, follow the manufacturer’s instructions on how to install it correctly.

No doubt, with the right weatherstripping and a little patience, you’ll be able to patch up those gaps and keep the cold air outside, where it belongs. As you continue through this process, remember that every nook and cranny counts. The more you can seal off, the more heat you’ll retain, and finally, your cozy home will stay that way.

Apply Door Sweeps

One powerful tool in your draft-fighting arsenal is the door sweep. This type of weatherstripping is perfect for sealing the tricky gap found at the bottom of the doors. Before you brush off this solution, realize it’s critical to preventing drafts and maintaining your home’s coziness.

Let’s get into the meat of the matter: what exactly is a door sweep? It’s a long strip of material usually made from plastic, aluminum or stainless steel, affixed to the bottom of the interior side of a door. The smooth surface of the sweep glides over your floor, creating a barrier against cold air sneaking in under the door.

Choosing the right door sweep is simple. Here’s what you need to do. Look for a durable, high-quality door sweep that can withstand the amount of foot traffic your door sees. Aluminum and stainless steel options are robust, while plastic sweeps may wear down faster. Consider the sweep’s bristles – these should be enough to seal the gap without scraping your floor. Door sweeps come in different sizes, so measure your door’s width to get the best fit.

Once you’ve found the perfect door sweep, it’s time to install it. You’ll need a drill, screws and the door sweep. Remember, having the correct tools for any job is critical. Fix the door sweep to the bottom of your door, make sure it’s flush with the floor when the door is closed.

You’ve now leveled up in your draft proofing journey. With that pesky under-door draught sorted, we can now move on to look at other areas where chilly winds might be sneaking in. Stay tuned for our next advice: weatherstripping for windows. This could be another great step in making your home a fortress against icy gusts from outside.

Install a Draft Stopper

Carrying forward from the importance of door sweeps, we’ll now move onto our next fix – draft stoppers. They’re an equally crucial tool that aids in sealing off drafts seeping from the spaces around doors.

Often confused with door sweeps, draft stoppers are usually placed on the inside of your door and efficiently block the air from the bottom. They’re different from door sweeps, which cover gaps from the outside. You could consider draft stoppers to your arsenal of defenses against cold drafts. They can be your secondary line of defense, offering much-required support to your already installed door sweeps.

Over time, you’ll notice that your door sweeps may wear down or lose their sealing power. It’s here where your draft stoppers come into play. They help maintain the barrier against cold air whilst your door sweep’s effectiveness decreases. Paired together, draft stoppers and door sweeps present united resistance against these unwelcome drafts.

How do you choose an effective draft stopper? Size matters. To ensure maximum efficacy, your draft stopper should snugly fit the width of your door. Draft stoppers come in a variety of materials, so pick one that complements your door. Soft fabric, vinyl-covered foam, and even insulated PVC are some options to consider.

Installation isn’t too complex either. Much like your door sweep, ensure your draft stopper is position-wise flush with the bottom of the door. That way, it’ll serve its purpose best each time you close the door. When the door opens, the draft stopper should easily move with it, proving no hindrance to use.

With draft stoppers in place, you’re moving ahead in your mission of draft-proofing your home. Remember, the best protection against drafts is a combined approach – and draft stoppers can play a notable role in that combination. We hope this information equips you well in your battle against drafts. Next, we’ll be peeping through windows – specifically, weatherstripping for windows – that could turn another frontier in your draft-proofing mission. Stay tuned.

Regular Maintenance Tips

Proper upkeep of your draft stoppers and door sweeps is one aspect that you should never neglect. Preserving these devices in good condition can significantly increase their lifespan and efficacy. Check them routinely for any signs of wear and tear.

Count on regular inspections. Door sweeps and draft stoppers ain’t immortal. Make it a habit to inspect them at least a couple of times per year. Look for cracks, gaps, and signs of degradation in the material. These could be clear indictors it’s time for replacements.

Ensure proper fit. If drafts are still getting through even though your door sweeps and draft stoppers appear in good shape upon inspection, it might be due to the incorrect size. Remember, the fit should be flush and snug, but not too tight where it would prevent the door from closing easily.

Seasonal changes could cause your doors to expand or contract altering the fitting — it’s advisable to check fit again when seasons change.

It’s also crucial to consider the installation process. Door sweeps and draft stoppers need to be installed in a specific way to work best.

Cleanliness goes a long way. Keeping your draft prevention devices clean is another excellent maintenance tip. Dust buildup can affect their ability to prevent drafts. Use a damp cloth for routine cleaning. For stubborn grime, mild soap and warm water can be helpful.
