5 Things You Can Do to Stop Winter Drafts

As an energy auditor there is a lot of repetition to what I do. I see the same issues over and over again. 

This is great for Maryland BGE and Pepco customers that need help finding ways to improve comfort around their home. 

Here are five things you can do around a home that will make it more cozy in the winter.


1. Seal Recessed Light Fixtures

The first thing you can do to save energy at home and reduce drafts is seal up you recessed lights in ceilings that are below the attic.  These common fixtures are secret gateways to the attic and there is no doubt your warm, conditioned air is sneaking right out. 

Most older recessed lights have ventilation holes so that heat from the old incandescent bulbs can escape. 

Pepco and BGE customers with recessed lights typically have some of the biggest bills and comfort complaints.

How Should it Look?

It is always best to seal recessed lights from the attic.  Covering the fixure and sealing the cover at the base is key.  Now the air barrier is restored and the home will be less drafty.

When sealing recessed lights from the attic is not possible, you can seal your recessed lights from the inside with an LED recessed light kit.


2. Seal Attic Floor Cracks, Holes and Gaps

Similar to the recessed light problem, there are other holes and cracks in the attic floor that will lead to the communication of air between the inside of the home and the attic, or outside.

Take your light switch on the wall as an example.

Wires run through the walls to hook up to electrical outlets and switches creating pathways for air to connect between the inside and outside (attic).

Foam sealant can be purchased at the hardware store and it can be applied to the tops of walls, around light fixtures and to seal up holes drilled for electrical wires.  All of these voids contribute to a high bill and uncomfortable living space.

3. Seal Accessible Leaky HVAC Ducts

Improving home comfort can be achieved when you put resources in the right place. 

According to the EPA and other studies, the HVAC ducts in your home can be leaky enough to account for up to as much as 30% of a household's total energy loss.

Sealing ducts is not something that needs to be done by a contractor. 

This is a "weekend warrior" type of project that requires a little patience, a few materials and a little know how.  Sealing ducts near the air handler will also help you the most and those are usually the places that are most accessible.

One way to fix leaky ducts is to use two-part spray foam.

Sealing ducts with mastic is another option to improve your home comfort.

4. Seal and Insulate the Attic Hatch

If you want to save energy at home and improve comfort, be sure to think about all of the places that you have access to an attic around your house.  It is important to treat all of them. 

Typically, the attic access points around a house are made from 1/4" plywood or drywall.  This is no way to separate the inside of your home from the attic (outside).  A few pieces of insulation and a 10' piece of weatherstripping can go a long way!

5. Install a Chimney Balloon

If you have a fireplace, then you have another great way to improve your home comfort. 

Most people keep the damper closed when the fireplace is not in use, but usually it is made of metal.  Chances are there is nothing stopping the flow of air through the chimney damper flap and out.  Using a very simple blow up type device can really help to move the needle and decrease energy usage and improve comfort.

Save home energy

A great way to save energy at home and improve comfort is to seal the chimney with an attic balloon.

The attic ballon has a stem that can easily be accessed to blow up the device and create a nice seal in the chimney.


Looking for these five things around your home and resolving one or two of them can go a long way towards better comfort and having a lower energy bill.
