Replacing Doors = More Ways to Save

We’ve already discussed how replacing drafty windows can help your home become more energy efficient. We’re happy to share that there are even more ways to save!

Keeping your home accessible yet safe and not letting cold air enter are the primary functions of your doors and windows. Over time, when these become worn and cannot function as intended, you need to get them replaced. The maintenance of heat within your home and consequent energy bills are affected by the quality of the replacements. Guardian Windows & Doors does its utmost to ensure your expectations and needs are met.

Using appropriate weatherstripping materials is another crucial aspect of replacing your doors effectively. It is imperative to choose materials that can withstand the wear and tear caused by frequent opening and closing of doors and temperature changes. Some excellent examples of such materials are silicone and vinyl.

There are several benefits to replacing your doors, including:


  • Better property value: A new door can instantly boost the appearance of your home's exterior, improving its overall aesthetic appeal and potentially increasing its resale value.

  • Noise reduction: High-quality doors with proper insulation can significantly reduce outside noise, making your home a more peaceful and comfortable place to live.

  • Low maintenance: Newer doors typically require less maintenance than older ones, which can save you time and money in the long run.



Not only do windows allow air leaks, but your exterior doors also do as well. Whether they lead to your front yard, back patio or attached garage, the doors on your home let in large amounts of outdoor air into your home. Worn weatherstripping around your doors creates drafts in your home, causing your furnace to work harder to heat your home. Your door threshold itself may also be letting in air. You must adjust your threshold if you can see the light under or around your door.


Guardian Windows & Doors in Sudbury offers our expert door replacement services to help you prevent cold air from entering your home in the winter. We replace weatherstripping, adjust the threshold, offer airtight doors, and add curb appeal to your home.
