Drafty Dilemma: Retrofit vs. Replacement Windows for Your Home

Drafty windows can be more than just a source of discomfort – they can also sap your energy budget and leave your home feeling frosty in winter and sweltering in summer. Deciding whether to retrofit or replace your windows can feel like a daunting task, shrouded in confusing options and conflicting advice. But fear not, fellow homeowner! This comprehensive guide will equip you with the knowledge and insights needed to make an informed decision, transforming your drafty windows from energy vampires into comfort champions.

Understanding the Contenders: Retrofit vs. Replacement

Retrofit windows work their magic by adding a layer of insulation and functionality to your existing window frames. They offer a range of options, from detachable interior storm windows to permanent interior inserts that replace the sash and glass. Think of them as giving your old windows a superhero makeover!

Replacement windows involve the complete removal of your existing window frame and installation of a brand new unit. They come in various styles and materials, offering maximum energy efficiency and modern features. Think of them as a clean slate for your window openings.

Choosing Your Champion: Weighing the Pros and Cons
