Jul 17, 2023


Are you experiencing constant temperature fluctuations in your home? Do you feel a chilling breeze even when all your doors and windows are closed? If so, it is highly likely that your house has drafts. Drafts can lead to significant energy loss and discomfort, making it essential to identify and eliminate them. In this guide, Narducci Electric, the leading electrical service provider in Philadelphia, will walk you through the process of locating drafts in your house.

Understanding Drafts

Drafts occur when there is an unwanted flow of air through gaps, cracks, or openings in your home's structure. These air leaks can often go unnoticed but can have a profound impact on your energy bills and overall comfort. By identifying and sealing drafts, you can enhance the energy efficiency of your home and create a more comfortable living environment.

Tools You'll Need

  • Thermometer
  • Incense stick or smoke pencil
  • Flashlight
  • Weatherstripping materials
  • Caulking gun
  • Door sweeps or draft stoppers
  • Window insulation film

Step-by-Step Guide to Locating Drafts

1. Check Windows and Doors

Begin your draft-hunting journey by inspecting all windows and doors in your house. Run your hand along the edges and feel for any air movement. Pay close attention to corners, bottom edges, and the area where the window sashes meet. If you notice air coming in, mark the location as it will require weatherstripping or caulking to seal the gap properly.

2. Utilize a Thermometer

Grab your thermometer and move towards each window and door. Measure the temperature near these openings. If you notice a significant drop in temperature, it indicates a potential draft. Note down the affected areas for further investigation.

3. Detect Drafts with Incense Stick or Smoke Pencil

An incense stick or smoke pencil is a fantastic tool for visualizing drafts. Light the incense stick or smoke pencil and carefully move it around suspected areas. If you notice the smoke being disturbed or blown away, it is a strong indicator of air movement. Take note of these locations to address later.

4. Inspect Electrical Outlets, Switches, and Light Fixtures

Often overlooked, electrical outlets, switches, and light fixtures can also be sources of drafts. Hold your hand near them and check for any air movement. If you feel a draft, it may be due to gaps in the electrical box or wiring. Consider consulting a professional electrician, like Narducci Electric, to seal these openings safely.

5. Assess Attic and Basement

Your attic and basement are areas where drafts commonly originate. Inspect these spaces for any visible openings, cracks, or gaps. Use a flashlight to help you in the process. Pay attention to the areas where the walls meet the floor and ceiling, as well as around pipes, ductwork, and vents.

6. Evaluate Exterior Wall Penetrations

Walk around the exterior of your house and closely examine any wall penetrations. These may include vents, utility meters, electrical wiring, or plumbing access points. Ensure that all these openings are properly sealed to prevent drafts from entering your home.

7. Take Note of Other Susceptible Areas

Drafts can also sneak in through other vulnerable areas in your house, such as gaps around recessed lights, attic hatches, and chimney dampers. Make sure to thoroughly investigate these areas to identify and eliminate any potential drafts.

Addressing Draft Issues

After identifying the locations of drafts in your house, it's time to address these issues and make your home more energy-efficient. Depending on the severity of the drafts, you can apply weatherstripping to doors and windows, use caulking to seal gaps, install door sweeps or draft stoppers, and even consider window insulation film for increased efficiency.
