A cold draft sneaking in under the front door can make an otherwise comfortable home feel surprisingly chilly, and you do not necessarily have to wait for a handyman to fix it. A temporary solution can often be installed in minutes while you wait for a permanent door repair.
Start by finding exactly where the air is entering. On a windy day, slowly move your hand around the bottom and sides of the closed door. You can also hold a thin piece of tissue near the edges and watch for movement. If the paper moves noticeably, you have likely found an air leak.
The easiest temporary solution is a draft stopper. A commercially available door draft blocker can be placed directly along the inside of the door to reduce the amount of cold air entering underneath. If you do not have one, a tightly rolled towel or blanket can work as a short-term solution. Position it firmly against the bottom of the door, but make sure the door can still open easily in an emergency.
For a longer-lasting DIY solution, adhesive weatherstripping is one of the simplest options. Measure the bottom and sides of the door, purchase appropriately sized weatherstripping, clean and dry the surface thoroughly, and apply the strip along the area where the door closes against the frame. Properly installed weatherstripping helps create a tighter seal without preventing the door from opening and closing normally. If the cold air is coming specifically from the gap underneath the door, a door sweep can provide a more durable solution. A door sweep attaches to the bottom of the door and closes the space between the door and threshold. It is particularly useful when there is a visible gap across most of the bottom edge.
For very small cracks around the fixed door frame, removable caulk or appropriate sealant can provide a temporary solution. If you eventually discover that the actual problem is a gap between the door frame and the surrounding wall, that may require a more substantial air-sealing repair rather than simply adding something to the bottom of the door. Gaps around exterior doors can be significant sources of unwanted air leakage.
Before applying any adhesive product, clean away dust, grease, and moisture from the surface. A dirty or damp surface can prevent the weatherstripping from sticking properly. Also check whether the door itself is sitting correctly in the frame. Loose hinges, a misaligned latch, or a damaged threshold can create gaps that weatherstripping alone may not completely solve.
If you are trying to reduce your heating bill, sealing the draft is worth addressing rather than simply turning the thermostat higher. Unwanted air leakage can waste energy and make rooms feel uncomfortable. Improving the seal around doors and windows can improve indoor comfort while helping your home use heating and cooling energy more efficiently.
One important mistake to avoid is permanently sealing ventilation openings that your home needs for safe operation of fuel-burning appliances. Weatherization should reduce unwanted drafts without interfering with required ventilation or combustion air. If you have a gas furnace, boiler, fireplace, or other fuel-burning appliance and are unsure which openings are safe to seal, ask a qualified professional.
For tonight, the simplest solution is a tightly rolled towel or purpose-made draft stopper at the bottom of the door. When the handyman arrives, ask them to inspect the threshold, door sweep, weatherstripping, hinges, frame alignment, and any gaps around the door. A proper repair will give you a much better long-term result than continually blocking the draft with towels.
A small gap under a front door may seem insignificant, but sealing it can make the room noticeably more comfortable. With a few inexpensive home improvement supplies and a little attention to where the air is entering, you can reduce the draft now and leave the permanent repair for later.
