Decks
Custom decks, built for how you live outside
A good deck starts with how you want to use it: dinner off the kitchen, a shady corner, room for the grill. We build custom decks and talk through every material choice with you.

Decks are the part of our work that is about living space rather than weather, but the same lesson applies: the parts you cannot see matter most. Footings carry the load, and the ledger board and its flashing keep water out of the house wall where the deck attaches.
We build custom decks for homeowners throughout our service area, from O’Fallon out to the St. Louis suburbs. You get a free estimate, a straight conversation about wood and composite, and a plain explanation of the deck rules where you live.
Free estimate
Tell us about the project and we will come out, measure and talk through options. No obligation.

Cracked, checked or soft boards
The USDA Forest Products Laboratory says most wood decks are retired because of cracks and checks that timely finishing could largely have prevented.
A wobbly feel
Movement underfoot, or when a crowd gathers, points to worn connections, posts or bracing.
Rust or rot at the house
Rust streaks below the ledger or soft wood behind it suggest water is reaching the house framing.
Railings that move
Local deck guides require guards at least 36 inches tall once a deck is more than 30 inches above grade. A railing that shifts is a safety problem first.
A deck you never use
Wrong size, wrong spot or no shade. A new layout can turn it into the room you use most all summer.

Options
Wood or composite: the honest trade-offs
Pressure-treated pine
The standard for deck framing; St. Peters requires it for joists, beams and ledgers. As decking it needs a penetrating finish, and the Forest Products Laboratory puts a water-repellent preservative’s life at about a year on exposed deck surfaces.
Cedar
Naturally decay resistant and good looking for decking, rails and trim. St. Peters allows it for those but not for joists, beams or ledgers.
Composite
Lower maintenance, not no maintenance. Forest Service research found that early wood-plastic boards developed mold, decay and weathering problems, and makers added fungicides, mildewcides and UV stabilizers. Ask what a board is made of and get its warranty terms in writing.
Deck rules around here
Every city publishes its own deck rules and they change, so check yours before work starts. These are the basics from local deck guides as of 2026.
- Permits: St. Charles County exempts only decks of 200 square feet or less that sit no more than 30 inches above grade, are not attached to the house and do not serve the required exit door. St. Peters requires a permit to build, repair or replace any deck, and Wentzville requires one for any attached deck.
- Footings: piers at least 30 inches deep in St. Peters, Wentzville and unincorporated St. Charles County.
- Ledger flashing: St. Peters’ guide has the siding removed where the ledger attaches and flashing run from under the siding, over the top of the ledger and down. The American Wood Council’s guide requires corrosion-resistant flashing at any ledger on a wood-framed wall.
- Brick and stone: the American Wood Council’s guide prohibits ledgers on brick, stone or masonry veneer, and Wentzville requires engineered plans for decks attached to veneer.
- Fasteners: hot-dipped galvanized or stainless steel for ledger connections, per Wentzville’s guide.
Before anyone digs
Footings mean digging, and Missouri law requires a utility locate first. Whoever digs should contact Missouri 811 at least three working days ahead; the service is free.
Keeping a wood deck going
The Forest Products Laboratory recommends penetrating finishes, such as water-repellent preservatives and semitransparent stains, over paint and solid stains, which tend to trap moisture and peel. If boards came with a factory water repellent, the lab suggests letting them weather 2 to 3 months before finishing.

Fixed on the spot
I had a leak in my roof and called a couple different roofing companies to check it out. None of them could figure out where it was coming from, they just told me I’d need a whole new roof. Then I called Correll Roofing Company. Curtis came out…
Knowledgeable, polite, and responsive
I contacted Correll Roofing about some shingles that I lost off of my roof during this last round of high winds that we experienced. Jon responded to my inquiry quickly, came out to my home and replaced the missing shingles in a very timely manner.…
Reassured me and walked me through the process
I had the pleasure of working with Devin Stinson and am currently getting my roof replaced. I had waited almost too long to do it as I am a first time homeowner. The process was a little scary but Devin reassured me and walked me through the process…
FAQ
Decks: questions
Ask us anything at (314) 222-9529.
Can a deck attach to my brick house?
Not with a ledger fastened to the brick veneer. Those decks are built to stand on their own posts or engineered for the job, and Wentzville, for one, requires stamped plans.
Wood or composite: which lasts longer?
Either can last when it is built and kept up well. Wood needs regular finishing, composite needs cleaning and a sound formulation, and the framing underneath is treated lumber either way.
Can you build a deck for a hot tub?
A hot tub adds a lot of weight, and Wentzville requires engineered, stamped plans for decks that support one. Plan for it from the start rather than adding it later.
What should I have ready for a deck estimate?
A rough idea of size and use, any HOA rules for your subdivision, and your plot plan if you have it, since permit applications usually ask for one.
