A badly fitted door can be made to work and operate at its best with some simple tools and attention. A building's entrance door is a crucial part since it protects the interior from outside elements, adds security to the property, and improves the building's overall energy efficiency. 

All of these factors are justifications for fixing an entry door to make sure it closes securely. Here are the two ways to get the door working correctly again if your door keeps from closing because of the weather stripping:

Is Weather Stripping Necessary?

Your home's energy efficiency depends heavily on the tiny bits of weather stripping between your doors and frames.

When it comes to preserving your home's maximum energy efficiency, many homeowners undervalue the enormous importance of properly maintained weather stripping materials. The weather stripping is often attached to the doorframe so that when the door is closed, light and air cannot leak through the opening.

The components are carefully sized and fitted to seal any gaps that would otherwise exist when your door is closed. During both extremely hot and extremely cold months, weather stripping is useful in lowering energy expenditures. 

If your property doesn't have the right weather stripping, you're simply letting money escape through your windows and doors. Without sufficient weather stripping, air leaks can account for up to 40% of a home's heating and cooling losses.

Also, more harm than just higher monthly energy expenses can result from air leaks. In the winter, warm air escapes from your house, and in the summer, it seeps in, carrying moisture in the form of water vapor. 

This moisture has the ability to seep into your insulation and walls, causing significant harm and perhaps spawning mold and/or mildew. In other words, adding weather stripping to your doors can work wonders.

How To Choose Weather Stripping?

If you hire a professional to install your weather stripping, they'll probably provide suggestions or decide on the ideal material for you. Otherwise, you can choose from a large range of weather stripping products, each of which is designed to meet a specific purpose around the house.

Start by examining the doors you wish to seal to focus your search. Separate those that swing from those that slide, and take note of the kinds of openings each has. 

The weather stripping material for sliding doors must allow for movement. For bigger gaps, you'll also require larger pieces of material.

When installing weather stripping yourself, use tools and supplies that you feel confident using. While some weather strips are made to adhere to them, others can need additional materials and tools.

How Often Should You Replace Weather Stripping?

The general rule of replacing weather stripping is generally every several years. Therefore, if it has been two or three years since you last changed or replaced the weatherstripping on your doors, it is a clue that they need to be replaced. 

You might need to replace weatherstrips considerably more frequently, though, depending on how frequently and how much the door is used. 

The weather stripping on frequently used doors, such as your front door, will inevitably deteriorate more quickly and become less effective at keeping heat inside your home, necessitating replacement once or twice a year.

Even while certain seasons may not see much use of specific doors, you should nevertheless inspect the weather stripping on each before winter and again before spring. It's not difficult to inspect the weather stripping, and if you know what to look for, you can quickly check all the doors in your house.

Final Thoughts

Always inspect all of your home's doors before making any repairs, not just the one you think needs it most. From garage door openings up to attic door openings, you should seal and insulate them. When harsh temperatures arrive, you'll be glad you did!
