Window terms can be confusing. Let's break one down:

Jamb Liner = The track your double-hung window sash slides up and down in. It's usually vinyl and contains the balance system (the "springy thing" that holds your window open).

When your windows won't stay up or feel hard to operate, it's often the balance system inside the jamb liner that needs replacing.

Good news? Our universal compression fith jamb liner kits fit most brands and come with everything you need! 🛠️

From start to finish, our standard is excellence. 👌

Quick way to figure out how old your windows are:
Check for a manufacturer label or stamp (usually on the jamb liner or bottom of the sash). It often includes a date code or manufacturing year.
No label? Look at your home's build date. Original windows are usually the same age as the house.

Why does this matter? Knowing your window's age helps you identify the brand and model, which makes ordering the right replacement parts way easier!

📸 Pro tip: Take a photo of any labels before you start your project. You'll thank yourself later.
