Unmatched Customer Service

We’re different from those unwelcoming, short-staffed, big-box chain stores.

Penny Window offers the personal service you expect from a local, family-owned St. Louis company. We know that if we keep our customers happy, the odds are they’ll keep coming back.

This philosophy hasn’t changed in over 60+ years.

We not only stand behind our products, we stand alongside our customers to deliver unrivaled service – service that doesn’t end once our truck pulls away. Our team of dedicated professionals is just a phone call away- ready to assist you before, during, and even long after your project is complete.

Our friendly staff has extensive knowledge and experience.

Whether you’re a homeowner or a contractor, we can supply you with the right materials and expertise to complete your new construction or home improvement project.
