Square Window Well Cover Testimonials


A. Rostvold, Rochester, Minnesota

The egress window well cover fits perfectly. I no longer have to worry about my kids and the neighbourhood kids playing near my front porch. During a big rainfall, the well stayed completely dry. The cover is lightweight, strong, looks amazing, and made in Wisconsin, USA.

Large egress cover with 3" overlap, installed on a concrete window well. The cover is custom-fitted to the well.

Jill F., Neenah, Wisconsin

We installed the well cover today and it looks great! Install was a breeze. Thanks again for putting up with me over the last year or two. Glad it came together so well.
