Our new website is live. Here is what changed, why we built it, and how it makes getting a free in-home estimate easier than ever.
Welcome to the new Penny Window. We have been St. Louis's window and door company since 1953, and our website finally reflects the way we actually work: family-owned, fair-priced, and built around getting you a free in-home estimate fast.
If you have shopped with us before, you will notice everything is easier to find. If this is your first time, you are in the right place. Here is a quick tour of what is new.
A faster way to get a free estimate
Most window and door questions do not need a sales pitch. They need someone to come out, measure, and give you a real price. So we put the things you came for up front: request a free in-home estimate in a few taps, or call us and reach a real person at the shop.
Everything we do, in one place
Our new service pages walk through replacement windows, entry and patio doors, siding, bay and bow windows, and our glass and window repair shop. You can see the window styles we install and the brands we carry before you ever pick up the phone.
- Replacement and vinyl windows in every common style
- Entry doors, storm doors, and sliding patio doors
- Low-maintenance siding to refresh and protect the whole exterior
- A true repair shop for foggy glass, broken panes, and worn hardware
The same family shop since 1953
A new website does not change who we are. We are still family-owned and operated. We still install with our own crews, never subcontractors. We still back our work with a limited lifetime warranty, and most jobs are still done in one to two days.
Take a look around. And when you are ready for a free in-home estimate, we are one call away.
