Regular inspections have helped homeowners find leaks from their doors and windows, and allowed them to address problems before they become worse. If you’re planning on doing one, take note of the below recommendations.
Why You Need to Inspect Your Doors and Windows
Every home has an insulated enclosure called an energy envelope. It consists of the attic, exterior walls and fenestrations, which include entry doors and windows. This enclosure helps reduce thermal transfer, which happens when heat moves between one space to another. This results in heat gain during hot seasons and heat loss during cold seasons.
In addition to insulation, doors and windows should be as airtight as possible. Leaky doors and windows would allow heat to pass through easily, which may defeat the purpose of the house’s insulation. They might also let rainwater through and raise indoor humidity levels.
How to Inspect Your Doors and Windows
Check your doors and windows to find existing leaks. Inspect the areas where weatherstripping would be. Water stains on these areas are clear signs that leaks have occurred, and weatherstripping needs to be replaced. Inspect the window sashes, and make sure they’re aligned properly. Modern window hardware like the ones we install on our replacement windows allow adjustments to sash alignment. Do the same for your entry doors.
If you have doors and windows with double-pane glass, check them for condensation. Condensation on the interior or exterior glass surface is normal, but if it occurs between the glass panels, it means the glass seal is broken, which opens the windows to air and water infiltration.
What Should You Do Next?
The first thing you need to do is check the door and window care and maintenance manual for instructions on replacing the weatherstripping. Some window types have rubber weatherstripping, which can be replaced with store-bought ones, while those with metal weatherstripping have to be replaced by a professional. Check your door and window warranties as it may include coverage for leaks and broken glass seals.
