#1 Address cracks, gaps, and insulation
Often the most effective way to increase the comfort of a room is by sealing cracks, gaps and adding insulation. By reducing the amount of cold, outside air that enters through hundreds of tiny (and not so tiny) gaps along the foundation and exterior walls, you not only make the basement temperature more comfortable, but you also reduce the amount of force that’s pushing warm air up and out of your house.
Cost – $20. Purchase a caulking gun and some expanding spray foam and start sealing. As a result you may be surprised at how the rooms in your home become less drafty.
#2 Use the right thermostat
Switch out your old manual thermostat for a programmable one. That way, you’re not paying for “extra” heat when no one is home or when you’re asleep.
Cost – $50-200. Programmable Thermostats are simple to install and can be set to automatically turn on and off at specific times of the day or night to maximize heating efficiency.
#3: Add insulation to your basement
Don’t ignore your basement. Basements are the biggest entryway for cold air to enter your home. Looking into ways to add insulation directly to the walls and ceiling will reduce the amount of incoming air. Also make sure to seal around the sill plate (the long piece of wood that sits directly on top of the foundation wall) for extra insulation.
Cost – Prices vary depending on the size of the space and the type of insulation.
