Where Homes Lose Air in Ocean City, DE

Air leaks may make your house unpleasant, frustrating and expensive. If you’ve suddenly noticed shifting home temperatures and drafts, it may be time to locate and repair air leaks in your Ocean City, DE home. Read on to learn where they occur and how to improve your home’s energy efficiency to save money in the long term.

Exterior Doors

Your door is leaking air if you can see light through it or move a dollar bill around it. Check the bottom seals and sweeps; if worn, replace them with flexible sealing gaskets that fit securely against the threshold. Also, install weather stripping and foam gaskets around doorjambs. This will improve your indoor air quality.


You can use incense as a low-tech leak detector. Switch off your HVAC system. If the incense smoke is being drawn outdoors or blown into the room, you’ve discovered a leak that requires caulking or weather stripping.

Think about the windows themselves: If you have old single pane windows, you may insulate them by adding low-E glass storm windows, which are affordable. They have the potential to prevent heat loss via glass. Plastic film insulator kits offer a more cost-effective seasonal alternative.


Examine your attic entrance panel or door to check for insulation. If it’s not insulated, it acts like an exit door and will leak conditioned air out of your home and into the attic space.

An attic air-sealing job might include making pouches of fiberglass insulation to fill open stud cavities and gaps beneath knee walls. You can also cover soffits with reflective foil and install aluminum flashing around your furnace and water heater flues.
