how to draft proof doors and windows cheaply

Drafty doors and windows are the bane of any homeowner’s existence. They not only make your home uncomfortable but also send your energy bills skyrocketing. The good news? You don’t need to break the bank to create a more airtight, energy-efficient home. There are plenty of affordable DIY solutions to draft-proof your doors and windows, often using materials you might already have lying around. In this guide, we’ll explore practical, cost-effective methods to keep the cold out and the warm in, making your home more comfortable and your wallet happier.

Identifying Drafty Areas

Before you start applying any fixes, it’s crucial to pinpoint exactly where the drafts are coming from. This saves you time and money by focusing your efforts on the problem areas. Here’s how you can do it:

The Candle Test

One of the simplest methods is the candle test. On a slightly breezy day, light a candle and slowly move it around the edges of your windows and doors. If the flame flickers or moves, you’ve found a draft. Be careful not to hold the candle too close to any flammable materials.

The Hand Test

If you don’t have a candle, simply move your hand slowly around the edges of doors and windows. You’ll be able to feel a change in temperature or a slight breeze if there’s a leak.

Visual Inspection

Sometimes, the source of the draft is visible. Look for cracks or gaps around window and door frames, worn or damaged weatherstripping, and openings under doors. These are all potential culprits.

Cost-Effective Draft-Proofing Solutions

Once you’ve identified the areas needing attention, it’s time to take action. Here are some budget-friendly methods you can use to draft-proof your home:

Weatherstripping: The First Line of Defense

Weatherstripping is one of the most effective and inexpensive ways to seal gaps around windows and doors. It comes in various materials, such as foam, felt, rubber, and vinyl, each with its own advantages.

Foam Weatherstripping

Foam is the most affordable option and is great for filling irregular gaps. It’s easy to install—simply peel off the adhesive backing and stick it along the frame. It’s best for low-traffic areas because it can wear down quickly.

Felt Weatherstripping

Felt weatherstripping is another inexpensive option, but it’s not as durable as rubber or vinyl. It’s best used in sheltered areas and might need replacing more frequently.

Rubber Weatherstripping

Rubber is more durable than foam and felt and is a good option for doors and windows that get a lot of use. It’s available in various profiles, so be sure to choose one that fits your gap size.

Vinyl Weatherstripping

Vinyl is one of the most durable options, resistant to moisture and temperature changes. It’s a bit more expensive but can save you money in the long run thanks to its longevity. It’s available in various shapes and sizes to fit different needs.

Installation Tips: Clean the surface where you’ll be applying the weatherstripping, measure carefully, and make sure the adhesive makes a good seal. Replace weatherstripping when it becomes cracked, brittle, or flattened.

Caulking: Sealing Gaps and Cracks

Caulk is another essential tool for draft-proofing. It’s perfect for sealing cracks and gaps around window frames, door frames, and even where the trim meets the wall. There are various types of caulk, including:

Acrylic Caulk

Acrylic caulk is affordable and easy to paint, making it a good choice for interior areas. It’s also relatively flexible, so it can handle minor expansion and contraction.

Silicone Caulk

Silicone caulk is more durable and water-resistant, making it ideal for areas exposed to moisture, such as exterior window and door frames. However, it’s not paintable and can sometimes be tricky to work with.

Latex Caulk

Latex caulk is a versatile choice, offering a balance between flexibility and paintability. It’s a good option for both interior and exterior applications.

Installation Tips: Clean the area before applying caulk. Cut the tip of the caulk tube at an angle and apply it in a smooth, steady bead. Use a wet finger or a caulking tool to smooth out the bead and achieve a clean finish.

DIY Draft Snakes: A Cozy Solution

Draft snakes are fabric tubes filled with insulating material, designed to block drafts from under doors and windows. They are incredibly easy to make, often using materials you might already have at home.

How to Make a Draft Snake

You’ll need some fabric (an old towel, blanket, or even a piece of sturdy fabric from your craft stash will do), filler material (rice, beans, old rags, or polyester stuffing), a needle and thread (or sewing machine), and some measuring tape. Measure the width of the door, add a couple of inches, cut your fabric to the size. Sew along three edges, fill with your chosen material, and sew closed. Place it snugly against the base of the door to prevent drafts.

You can also find pre-made draft snakes if you’re not in the mood for DIY. They come in various lengths and designs to suit your needs.

Window Film: An Affordable Insulating Layer

Window film is an affordable alternative to replacing windows and can significantly reduce heat loss. There are two main types:

Shrink Film

Shrink film is applied to the inside of your window frame and then heated with a hairdryer, causing it to shrink and create a tight, insulating layer. It’s a cost-effective way to add an extra layer of protection against drafts. You’ll need a double-sided tape, a roll of plastic shrink film, and a hair dryer. Tape the plastic around the window then use the hair dryer to shrink the plastic until you have a tight, wrinkle-free fit.

Low-E (Low Emissivity) Film

Low-E film is designed to reflect heat back into your room in the winter and away from your room in the summer. It’s more expensive than shrink film but offers better insulation and energy efficiency. It applies with an adhesive and is cut to the shape of the window. Installation is easy for a small window, but can be more complicated for a large window.

Heavy Curtains or Blinds: Adding Another Layer

While not a standalone solution, heavy curtains or blinds can significantly reduce drafts, especially when used in conjunction with other methods.

Thermal Curtains

Thermal curtains are specifically designed to insulate your windows and keep drafts at bay. They’re made from thick, layered fabric and often have a thermal backing.

Blackout Curtains

Blackout curtains, while primarily designed to block out light, also provide a decent level of insulation and can help reduce drafts.

Cellular Blinds

Cellular or honeycomb blinds have a unique construction that traps air in individual cells, creating an insulating layer. They’re a great option for keeping your home comfortable and energy efficient. They will need to be professionally measured and installed.

Door Sweeps: Blocking Under-Door Drafts

Door sweeps are easy to install and very effective at blocking drafts that come in under your door. They’re available in various styles and materials, including:

Brush Sweeps

Brush sweeps have a row of bristles that fit snugly against the floor, effectively sealing gaps of varying sizes.

Rubber or Silicone Sweeps

Rubber and silicone sweeps are more durable than brush sweeps and create a tight seal against the floor. They are very effective for even gaps between door and floor.

Installation Tips: Measure your door and cut the sweep to the correct size. Remove the backing from the adhesive and press the sweep firmly against the base of your door. Check the seal and adjust if needed. For screw-in models, ensure the door sweep fits properly before securing it with screws.

Additional Tips for Reducing Drafts

Here are a few more things you can do to maximize your home’s energy efficiency:

Close Fireplace Dampers

If you have a fireplace, ensure the damper is closed when it’s not in use. An open damper is a significant source of heat loss.

Seal Electrical Outlets and Switches

Believe it or not, drafts can come in through electrical outlets and switches. You can purchase inexpensive foam outlet gaskets to seal them up.

Address Attic Leaks

Make sure your attic insulation is adequate and that any air leaks are sealed. This can have a dramatic effect on the overall temperature of your home.

Check for Foundation Issues

Cracks in your foundation can also contribute to drafts. Have your foundation inspected regularly and address any issues promptly.

Draft-proofing your doors and windows doesn’t have to be a costly undertaking. With these simple and affordable techniques, you can significantly reduce drafts, lower your energy bills, and make your home a more comfortable place to be. Don’t wait for winter to come knocking; start sealing those drafts today!
