Putting a Stop to Heat Loss

05 January 2021

Air sealing is one of simplest yet most effective ways to lock in the heat and stop it from escaping out those cracks and gaps in your home. With the right solution, it is a hugely cost-effective way to cut heating costs, increase comfort, improve durability and create an all round healthier home environment. The most common places air can sneak through are doors and window frames, attic hatches, cents and fans, baseboards and electrical outlets.


Caulk or caulking is a sealing material used to seal joints or seams to prevent leakage in various structures and piping (like no more gaps). Most caulk products come in disposable cartridges that fit in a caulking gun. The best time to apply caulk is during fine weather – always make sure the area is clean and dry before application. If possible, try caulk window and door frames at a consistent angle and in one straight, continuous stream to avoid stops and starts which are less effective.


Whether it’s a door or window frame, caulking is a great way to cover up cracks and small openings less than one quarter-inch wide on the stationary objects in your home that don’t open or close.  Caulking can also prevent water damage inside and outside your home when used around ceiling fixtures, drains, faucets and other plumbing fixtures. If the caulk starts to ooze out of a gap, use a putty knife to push it back in to avoid any gaps in the sealant where air can get through.


If you’re trying to seal components that move such as doors and usable windows, weatherstripping is the best option. Always choose a type of  weatherstripping capable of withstanding the elements – from  friction to temperature changes, weather and the wear and tear the area might be susceptible to. This means if you’re applying it to a door bottom, weatherstripping could drag on carpet or wear away from feet walking in and out. It’s also  important to make sure you work with the sliding of panes whether it’s up and down, out or sideways. The weatherstripping should always seal well when the door or window is closed, without restricting it from opening.

CHOOSING THE RIGHT WEATHERSTRIPPING Choose the right product for the location. Felt and open-cell  foams can be  cheaper but they’re also often ineffective when it comes to blocking airflow. While vinyl is a bit more expensive, it holds up well and resists moisture. Metal weatherstripping is both affordable and long-lasting – and also adds a nice aesthetic to older homes.
