Markham, IL Window Well Cover FAQ
Can you add a cover to my existing metal grate?
Yes — overlay polycarbonate covers are mounted directly onto existing grates to block rain and debris.
When do I need a vertical extension?
Extensions are used when the basement window sits higher or opens outward and needs extra clearance.
Why choose a sloped window well cover?
Sloped covers help rain and snow slide off, reducing water buildup and keeping wells cleaner.
