Yes, most Pella windows carry a limited lifetime warranty, but it’s not full coverage on every part. It applies to the original purchaser for as long as they own and occupy the home, and it typically transfers to a new owner for up to 10 years after a sale.
Coverage varies by product line and material (wood, vinyl, fiberglass). Non glass components like frames and hardware are often covered for a lifetime, while finishes and paint usually carry 5 to 10 year terms, and glass coverage ranges from 5 to 20 years.
Since “limited” excludes things like accidental damage or normal wear, it’s worth checking the specific warranty document for your model.
