Local Expertise
Decks In O’Fallon, Missouri And Illinois
Both O’Fallons are ours, the one in St. Charles County and the one in St. Clair County. Same crews, same warranty, same number to call. What your address changes is which inspector we are booking and how the week gets scheduled, and we sort that out before you have to think about it.
The ground is the practical difference. On the Missouri side the subdivisions sit on rolling land with walkout basements, so the kitchen door is often a full story above the yard and the deck has real height to deal with. On the Illinois side lots are generally flatter and decks sit closer to grade, which changes the framing, the clearance underneath and how quickly the wood goes.
The Product
Choosing Between Composite And Lumber
Both materials build a good deck. The right answer depends on how much upkeep you want to sign up for and how long you plan to be in the house.
- Deckorators composite: capped, fade and stain resistant, effectively no maintenance
- Pressure-treated lumber: traditional look, lower initial cost, periodic sealing
- Matching rail systems, lighting and stair details either way
O’Fallon Specifics
Why These Deck Features Matter In O’Fallon
On the Missouri side
A deck a full story up makes the stairs, the rail and the footing depth the real design work. Done properly you gain usable space underneath as well as the deck itself, which is the best return available on a walkout lot.
On the Illinois side
Closer to grade means less air under the frame and slower drying after rain. Clearance, post bases and material choice are what decide whether that deck lasts twelve years or thirty.
Two counties, two sets of paperwork
Decks are permitted and inspected in both cities, footings included, and the routes are not the same. We prepare the drawings and file with whichever authority covers your address, then schedule the footing inspection and the final around your build.

Testimonials
What Homeowners Say
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

Questions
O’Fallon Decks FAQ
How long does a deck build take?
Most residential decks take one to two weeks depending on size, height and rail system. Footings and inspections set the schedule more than the carpentry does.
Is composite worth the extra cost over lumber?
If you plan to stay more than a few years, usually yes: you stop paying for sealing and board replacement. If the budget is tight or the deck is small, treated lumber built well is still a good deck.
Which inspector comes out to my deck?
The one for your address. In Missouri that is the City of O’Fallon or St. Charles County; in Illinois it is the City of O’Fallon or St. Clair County. We book both visits and meet them ourselves.
Can you build the same deck design on either side?
Usually, with the caveat that the ground differs. A design drawn for a walkout in Missouri often needs rethinking on a flat Illinois lot, and we would rather adapt it than force it and hand you something that does not suit the yard.
