Deck Building
Central Iowa
Iowa summers are short and a backyard without a deck is a backyard that doesn’t get used.
Whether your old deck has become unsafe or you’re starting from scratch, Busy Builders designs and builds outdoor structures that hold up through the seasons’ freeze-thaw cycles, clay soil movement, and everything else Iowa throws at them.
A deck built right here lasts, and we build it right.

About Us
Since 2020, Busy Builders has completed over 1,000 construction and remodeling projects across Central Iowa.
We’ve built decks through Iowa winters, seen what happens to shallow footings and improperly flashed ledgers, and know exactly what this climate demands from an outdoor structure.
We build every deck to last, and we stand behind the work after we leave.
Our Mission
Honest material guidance and no upselling features the homeowner doesn’t need.
If a pressure-treated deck does the job, we say so. If the homeowner’s long-term plans warrant composite, we make that case with real numbers, not a sales pitch.
Our Vision
We want to be the registered general contractor that homeowners in Des Moines, West Des Moines, Ankeny, Waukee, Ames, Grimes, Johnston, Clive, and Urbandale call first and recommend without hesitation.
Every deck we build is a chance to earn that reputation.

How Do We Build Your Deck?
SITE ASSESSMENT & DESIGN
Before any material is ordered, we walk the yard and assess everything that affects the build: grade changes, soil type, drainage patterns, proximity to the home’s foundation, and sun and wind exposure.
Iowa soil types vary by region, which affects footing design and how posts are set from the start.
We discuss layout options, material choices, and budget at this stage so the homeowner has a complete picture before signing anything.
Permit requirements are confirmed for the specific city at this step.
Des Moines, Ankeny, Waukee, and other Central Iowa cities all have different thresholds and processing timelines.
You get a written design with cost and timeline before work begins.
- Full site assessment covering grade, drainage, soil, and foundation proximity
- Layout and material options presented with Iowa climate performance context
- City-specific permit requirements confirmed before any work is quoted
PERMITS & APPROVALS
Most attached decks and elevated decks in Iowa require a building permit, and skipping this creates problems at resale, with insurance, and with lenders.
The Iowa Building Code is administered through DIAL, and each city has its own submission and review process.
We pull all required permits, submit structural drawings where required, and schedule all inspections as part of the project scope.
Permit processing times vary by city, and we factor them into the project timeline up front so they don’t catch anyone off guard.
Review the Iowa DIAL permit submission process for your city’s specific requirements.
- Permit application filed for your city as part of the project scope
- Structural drawings submitted where required by local building departments
- All inspections scheduled and coordinated, homeowner doesn't have to manage a thing
LAYOUT & FOOTING EXCAVATION
The layout is staked out, and footing locations are marked before any digging begins.
Iowa’s 42 to 48 inch frost line is non-negotiable. Footings set above it will heave during freeze-thaw cycles and compromise the entire structure within a few winters.
Iowa’s various soil types require attention to footing diameter to provide adequate bearing capacity across seasonal moisture changes.
We call 811 utility locate before digging to locate underground utilities, which is required by Iowa law before any excavation. Footing holes are inspected by the city before concrete is poured in jurisdictions that require it.
- Layout staked and footing locations confirmed before excavation
- Footings dug below Iowa's 42 to 48 inch frost line on every project
- 811 utility locate completed before any digging begins, per Iowa law
FOOTINGS & POST INSTALLATION
Concrete is poured into tube forms at each footing location and allowed to cure before posts are set.
Post bases are embedded in the footing or attached with hardware rated for the load.
We never set wood posts directly in concrete, which traps moisture and causes rot.
Post height is cut to level so the beam sits flat across all posts. Iowa clay soil can shift seasonally, and proper footing depth combined with post base hardware is what keeps a Waukee or Ankeny deck level year after year.
- Tube-form concrete footings poured and cured before posts are set
- Post bases installed in hardware, no direct wood-to-concrete burial
- Posts cut to level for a flat beam seat across all footing locations
FRAMING: BEAMS, JOISTS & LEDGER
Beams span between posts, joists run perpendicular, and the ledger attaches the deck to the home’s band joist. This is the skeleton that carries everything above it.
Ledger attachment is one of the most critical steps on any attached deck because improper flashing here is the leading cause of rot and structural failure in Iowa decks.
We install flashing above the ledger to direct water away from the home, using materials compatible with pressure-treated lumber.
All framing lumber is pressure-treated and sized for the span and load per the Iowa building code. Joist hangers and structural hardware are galvanized or stainless steel because standard hardware corrodes within a few years in outdoor Iowa conditions.
- Ledger installation with proper flashing to prevent water intrusion into the home
- Pressure-treated beams and joists sized for span and load per Iowa building code
- Galvanized or stainless steel hardware on every joist hanger and connection point
DECKING INSTALLATION
Deck boards go down once the frame passes structural inspection. Board spacing is set to allow drainage and account for seasonal wood movement.
Boards installed too tightly in summer will buckle in Iowa’s humidity.
Composite boards are installed per the manufacturer’s specs for gap, fastener type, and end spacing because Iowa’s temperature swings cause the composite to expand and contract more than most homeowners expect.
Hidden fastener systems are available for a clean, screw-free surface on composite decks.
Wood boards are face-screwed and pre-drilled to prevent splitting.
- Board spacing set for drainage and seasonal movement in Iowa's climate
- Hidden fastener systems available for a clean finish on composite decks
- Manufacturer specs followed on all composite products for warranty compliance
RAILINGS & STAIRS
Railings and stairs go in after the deck surface is complete.
Iowa code requires railings on decks 30 inches or more above grade, minimum 36 inches tall, with balusters no more than 4 inches apart.
Stair stringers are cut and set to code-compliant riser and tread dimensions, which is what the city inspector checks at final inspection.
Post bases for railing posts are surface-mounted or through-bolted to the frame, never toe-nailed, which loosens over time.
Aluminum and composite railings are the best low-maintenance choice for Central Iowa’s weather and still look sharp after years of freeze-thaw cycles.
- Railing height and baluster spacing built to Iowa code on every project
- Stair stringers cut to code-compliant riser and tread dimensions
- Railing posts through-bolted to the frame for long-term stability
LIGHTING, ELECTRICAL & CUSTOM FEATURES
Lighting and electrical rough-in occur after framing, so wiring can be run cleanly through the structure.
Post-cap lights, recessed step lights, and outdoor GFCI outlets are the most common additions in Central Iowa deck projects.
Custom features: pergolas, built-in benches, planters, outdoor kitchens, and fire pit areas are built at this stage.
All electrical is done by licensed electricians and inspected to code. If you’re wondering whether a quality deck fits your budget before adding features, read our guide on building a quality deck under $10k.
- Post cap lights, step lights, and GFCI outlets installed and inspected
- Pergolas, built-in seating, and outdoor kitchen features built to spec
- Licensed electrician on all wiring, permitted and inspected before project close
STAINING, SEALING & FINAL WALKTHROUGH
Wood decks need a stain or sealer applied before they’re handed off. Bare pressure-treated wood left unfinished in Iowa’s climate will gray, check, and absorb moisture within the first season.
We apply stains and sealers rated for exterior use: transparent options show the wood grain, semi-transparent add color while showing grain, and solid stains cover grain for a painted look.
Composite and PVC decks don’t require staining, but receive a final inspection for proper gapping, fastener seating, and trim details.
We do a detailed walkthrough with the homeowner before calling the project complete.
Most Central Iowa deck builds run 1 to 3 weeks from footing dig to final walkthrough, depending on size, features, and permit processing time.
- Exterior stain or sealer applied to all wood decks before project handoff
- Final inspection of fasteners, gapping, trim, and all hardware connections
- In-person walkthrough with homeowner before project close

- Frequently Asked Questions
FAQs About Deck Building
IN Central Iowa
How much does it cost to build a deck in Central Iowa?
Costs depend on size, material, and features, and there are three main tiers to understand.
A basic pressure-treated wood deck with no custom features typically runs $15 to $25 per square foot.
A mid-range composite deck with railings and stairs falls in the $30-$50-per-square-foot range.
A high-end composite or PVC deck with a pergola, lighting, and built-in seating runs $50 to $80 or more per square foot.
Online calculators typically miss permit costs, deep footing requirements for Iowa’s frost line, and site prep.
Busy Builders provides a detailed written estimate before any work begins. See our full deck building cost guide for Des Moines for a complete breakdown.
Do I need a permit to build a deck in Iowa?
Yes, permits are required for most attached decks and for freestanding decks over a certain height.
Permits ensure footings, framing, railings, and stairs all meet the Iowa building code, and unpermitted decks create real problems at resale when buyers’ lenders and inspectors catch them.
Iowa Building Code is administered through DIAL, and each city has its own submission process.
Busy Builders handles all permit filings and inspection scheduling for every project. Review the Iowa DIAL permit submission process for your city’s specific requirements.
What decking material is best for Iowa weather?
Composite decking is the best all-around performer for Iowa’s freeze-thaw cycles, humidity, and UV exposure.
Pressure-treated wood costs less upfront but needs to be sealed every 1 to 2 years in Iowa’s climate, and skipping that step leads to cracking, graying, and rot within a few seasons.
PVC decking offers the highest moisture resistance and is the best choice for very wet or shaded sites.
Cedar is naturally rot-resistant but sits at a higher price point than pressure-treated and still needs regular finishing in Iowa.
See the full breakdown in our wood deck vs composite deck in Iowa guide.
How long does it take to build a deck in Central Iowa?
Most deck projects run 1 to 3 weeks from footing dig to final walkthrough.
Smaller ground-level decks with simple designs can be done in about a week.
Larger builds with multi-level layouts, pergolas, outdoor kitchens, or custom features take 3 to 4 weeks.
Permit processing time is the most common variable. Des Moines, Ankeny, and Waukee all process at different speeds, and we build those timelines into the project schedule upfront so there are no surprises.
Why do footings matter so much in Iowa?
Iowa’s frost line sits at 42 to 48 inches, and footings set above that depth will heave during freeze-thaw cycles, throwing the deck out of level.
Iowa clay soil expands when wet and contracts when dry, adding lateral pressure to posts and footings year-round.
A deck built on shallow footings in Iowa will show movement within 2 to 3 winters, with loose railings, uneven boards, and shifting stairs as the first signs.
Every Busy Builders deck footing is set below the frost line on every project, no exceptions.
Read more about ground-level vs elevated deck cost and design differences to understand how structure affects your options.
Can you add a pergola, outdoor kitchen, or other custom features?
Yes.
Pergolas, built-in seating, planters, fire pit areas, outdoor kitchens, and covered sections are all available and can be added to a new deck build or to an existing deck during a deck rebuild.
For larger outdoor projects, a deck can connect directly to a home addition like a sunroom or screened porch.
Custom features are scoped and priced during the design phase, so there are no cost surprises mid-build.
