Composite Decking Central Iowa
- Central Iowa General Contractor
What Is Composite Decking?
Composite decking is a manufactured board made from wood fiber and plastic. It does not need staining or sealing, and it is made to resist splintering. It handles Iowa freeze and thaw cycles with less upkeep than most wood. The tradeoff is cost, roughly double pressure treated per square foot.
The frame underneath is still wood, and it still needs footings below the frost line. Composite is a surface choice, not a substitute for building it right. See our full deck building service, or read our breakdown of composite deck costs, payback, and permits in Iowa.

- Frequently Asked Questions
Why Choose Composite?
No Sanding, No Sealing
That is the whole pitch. Composite gives you back the summer weekends that maintenance used to eat.
Built for Freeze and Thaw
Iowa winters are hard on wood. Composite is made to resist the splitting and cupping that freeze and thaw cause, though performance varies by brand.
Real Numbers Both Ways
Composite runs $30 to $50 per square foot against $15 to $25 for treated. We show you the ten year math, not just the install price.
Manufacturer Specs Followed
Joist spacing and gapping per the manufacturer. Getting it wrong sags boards and can void the warranty you paid for.
Same Foundation Standards
Composite surface, proper structure. Footings still go below the 42 inch frost line on every build.
Safer Underfoot
Hidden fasteners mean no popped nails, and boards are made to resist splinters. Wet or icy boards can still be slick, so ask about each brand's traction.

How We Build Your Composite Deck
SITE & SIZE PLANNING
We look at the yard, the door heights, how far off grade the deck sits, and how you plan to use it. Height above grade decides whether railings are required and changes the footing plan.
- Grade and height measured
- Layout and size planned
- Written scope and budget
MATERIAL COMPARISON & PERMITS
We price composite against pressure treated with real numbers, including what maintenance actually costs over ten years. Then we pull the permit. Board selection matters here, because joist spacing requirements vary by manufacturer.
- Composite vs treated priced honestly
- Manufacturer specs confirmed
- City permit handled for you
FOOTINGS BELOW THE FROST LINE
Iowa’s frost line is 42 inches, and footings above it heave every winter. We dig below it on every build and get them inspected before pour. This is the part nobody sees and the part that decides whether the deck lasts.
- Dug below 42 inches
- Inspected before pour
- Sized for the load

FRAME & LEDGER
The frame goes up in treated lumber with joist spacing set to the composite manufacturer’s spec, because wrong spacing causes sagging boards and can void the warranty. The ledger attaches to the house with proper flashing to keep water from getting behind it.
- Joist spacing to manufacturer spec
- Ledger flashed correctly
- Frame inspected
COMPOSITE BOARDS & RAILINGS
Boards install with hidden fasteners for a clean surface, with correct gapping for expansion. Railings go in at a minimum 36 inches where the deck sits 30 inches or more above grade, with balusters no more than 4 inches apart.
- Hidden fasteners, correct gapping
- Railings to Iowa code height
- Balusters under 4 inches apart
STAIRS, LIGHTING & WALKTHROUGH
Stairs, any lighting wired by a licensed Iowa electrician, and trim finish the build. We walk the deck with you and register the manufacturer warranty. Written warranty on workmanship (details provided in your contract).
- Stairs and trim complete
- Lighting wired by licensed pro
- Final walkthrough together

FAQs About Composite Decking in Central Iowa
How much does a composite deck cost in Central Iowa?
Mid-range composite with railings and stairs runs $30 to $50 per square foot. Pressure treated runs $15 to $25 for a basic build. High-end composite with pergola and lighting runs $50 to $80 or more. Your written estimate sets the real number.
Is composite worth the extra cost over pressure treated?
It depends on how long you are staying and how you feel about maintenance. Composite roughly doubles the up front cost and eliminates staining and sealing. Over ten years the gap narrows. We give you both numbers rather than pushing one.
How does composite hold up in Iowa winters?
Well, for most boards. It absorbs far less water than wood, so it resists the splitting and cupping that freeze and thaw cause. Snow removal is fine with a plastic shovel. Some boards get warm in direct summer sun, which we discuss during selection.
Do composite decks still need footings below the frost line?
Yes, in most cases. The decking surface has nothing to do with the structure underneath. Iowa’s frost line is 42 inches, and attached decks need footings below it. Some cities allow shallower footings for small freestanding decks, so we confirm your city’s rule.
Will the manufacturer warranty cover my deck?
Only if it is installed to their specification, including joist spacing and board gapping. We build to spec and register the warranty. Verify current coverage and limitations directly with the manufacturer before you buy.
Can you replace just the boards on my existing deck?
Sometimes. If the frame and footings are sound, resurfacing with composite is a real option and costs much less than a full rebuild. If the structure is failing, new boards on a bad frame is money wasted. We inspect and tell you straight.
