Use a slim tool, like a screwdriver or your finger, to assess the seals around your windows and doors for hidden openings. Any gap in the seal will let cold air pass into your house, which you don’t want. Your heating bills will be costly if you’re trying to warm a property that won’t retain heat properly, so fixing this error will save you money in the long run.
If you find a gap, fill it in with caulk to prevent heat escaping. Even if you have to hire a handyman to do this job for you, it’ll be less costly than overspending on your heating bills and spending winter cold in your home. Also don’t forget to check around the vents of your home for gaps, and keep an eye out where exterior pipes attach to your property. Inspect the exterior of your property to make a note of any potential access points for cold air, and double-check that everything possible is in place to prevent heat escaping.
