Windows, Siding, Doors, Roofs and Decks Across O’Fallon
There are two O’Fallons in our service area and this page is for both. O’Fallon, Missouri sits in St. Charles County, west of St. Peters. O’Fallon, Illinois sits in St. Clair County, next to Scott Air Force Base. They are roughly forty miles and one river apart, neither is a suburb of the other, and the first thing we establish is which one you are in.
That answer changes more than the drive. It sets the permit desk and the inspector, and it usually tells us what kind of house we are coming to. The Missouri city grew hard through the nineties and two-thousands, so most of its housing is large subdivision building on rolling ground with walkout basements, brick or stone across the front and panel elsewhere, with WingHaven and the neighborhoods around it holding many of the city’s highest-value addresses. The Illinois city is older at its center, with modest frame housing on the downtown streets, and newer neighborhoods that have grown steadily with Scott Air Force Base.
Serving Both O’Fallons
People give their location by subdivision or by the nearest crossroad, which is exactly how the two cities get confused with each other. These are the areas we cover around each of them.
Our exterior remodeling teams regularly serve homes in and around the following areas:
- O’Fallon, Missouri and WingHaven
- Dardenne Prairie and Lake St. Louis
- St. Peters and Cottleville
- O’Fallon, Illinois and Shiloh
- Fairview Heights and Swansea
- Belleville and Mascoutah
If your neighborhood is not listed above, we still serve homeowners around both O’Fallons.
What does not change is how we work. The same crews, the same warranty and the same phone number cover both, and the estimate happens at your house rather than from a map. If you are not sure which O’Fallon we should be talking about, tell us the street and we will sort it out.

O’Fallon grew along Manchester Road and filled in over about three decades, which is why so much of the city reads as one long build era: ranches, split-levels and split-foyers from the sixties through the eighties, on established streets with trees that are now full size.
Houses of that age are mostly on their second round of exterior work, not their first. The aluminum siding, the original steel entry door and the shallow ranch roof have often already been patched or partly replaced once, and what was put on in the nineties has now had a life of its own. Deciding what is genuinely done and what has a few good years left is most of what an estimate here is for.
Working across O’Fallon means we know how these houses were put together and where the water usually gets in: the rim joist behind an old deck ledger, the fascia under a gutter that has been overshooting, the corner where siding meets a brick front. We look at those before quoting a surface.

Testimonials
Customer Reviews
My experience with Shinnova was great. I want to thank Jeremy Sweatman for convencing me to get it done. My house looks new again and it is much warmer inside. The workers were very professional. They cleaned up after themselves every night before they left. Thank you very much.
We are extremely impressed with the professionalism of everyone we worked with Jeremy the bomb in explaining sale of windows and the process, Butch for guiding the installation and Dan for all the follow up on progress with delivery. Would recommend hands down we are actually on our second order. The Murphys
