Deck Installation in Underwood, IA

If you're ready to have a deck installed at your Underwood home, the installation process matters as much as the design.

We’ve completed deck installation projects across Underwood and the surrounding Pottawattamie County since 2008, with most jobs running 3 to 7 working days on site once materials hit your driveway.

What "3-Day Install" Actually Looks Like in Underwood

Most smaller Underwood installs (200 to 350 sq ft, ground-level or low-elevation) finish in 3 working days. Here’s how the time breaks down:

Day 1

Layout, footing excavation, concrete pour. Footing inspection scheduled with Pottawattamie County. We pour concrete in the morning and let it cure through the afternoon.

Day 2

Posts set, beams installed, joist framing laid out and fastened with Simpson Strong-Tie hardware. Joist tape applied across every horizontal member. Framing inspection scheduled.

Day 3

Decking installed (hidden fastener system on composite, surface-screwed on wood), railing system installed, stairs framed and decked, final cleanup. Final inspection closes the permit.

Larger installs (400+ sq ft, elevated, or with custom railing systems) run 5 to 7 working days but follow the same workflow. We don’t skip steps to chase the calendar.

Where the Speed Comes From

Three things make a 3-day install possible without cutting corners:

Pre-cut framing

We mill joists to length at our Omaha shop the day before crew start. The truck rolls in with the deck mostly cut to fit, not raw lumber.

In-house crew

The same crew that quoted your job is the crew swinging hammers.

Material delivery on day zero

We coordinate directly with TimberTech, Trex, and our local lumber yard so the delivery truck arrives the day before crew start, not three weeks early.

What Actually Gets Installed

Every Underwood install includes the same structural backbone regardless of decking surface. The difference is what you walk on:

Composite Decking (Most Underwood Installs)

Both install with hidden fasteners (no visible screws). Both come with optional under-deck drainage systems (Trex RainEscape) for second-story decks where you want a dry patio underneath.

Pressure-Treated Pine

Standard 5/4 deck boards in southern yellow pine. Surface-screwed with stainless or galvanized fasteners. $3 to $5 per linear foot.

Cedar

Western red cedar in 5/4 or 2×6 profiles. Fastened with stainless steel hardware to prevent corrosion staining. $6 to $9 per linear foot.

Railing Systems

Add-Ons We Install

Low-voltage deck lighting (post caps, riser lights, surface dot lights), pergolas and shade structures, hot tub framing reinforcement, built-in benches, integrated planters, screen rooms.

Iowa Code Compliance for Underwood Installs

Every install we complete in Underwood meets the 2015 Iowa Residential Code as adopted by Pottawattamie County. Specific items the inspector checks:

Footing depth at minimum 42 inches (we typically pour deeper; Iowa frost line is 58 inches statewide)
Ledger attachment with proper flashing and lag bolts at code-required spacing
Joist hangers rated for the load and properly nailed (not screwed)
Railing height at 36 inches minimum, 42 inches required if the deck is over 30 inches above grade
Baluster spacing under 4 inches at any point (the "4-inch sphere" rule)
Stair geometry with consistent rise and run, code-compliant tread depth
Lateral load connectors at the ledger (the tension-tie hardware that holds the deck to the house under wind load)

We pull permits through Pottawattamie County (712-328-5792). Install jobs that fall in the A-4 Loess Hills Zoning District trigger additional setback verification, which we handle on your behalf.

New Construction vs. Existing Home Installs in Underwood

Underwood is one of the fastest-growing Pottawattamie County towns, and a big share of our installs here happen on newly built homes. The two situations require slightly different approaches:

New construction installs

We coordinate with you (and sometimes your builder) before the home’s exterior siding is fully done. Sometimes we can install the ledger flashing during framing, which is the cleanest way to do it. Permit timing is usually faster because the lot grade and house specs are documented.

Existing home installs

The lot has been settled and landscaped, the house wall has whatever flashing it has, and we work with what’s there. We do a structural inspection of the rim joist before quoting an attached deck. On older Underwood homes where the rim joist is questionable, we often quote a freestanding alternative.

If you’re moving into a new build and want a deck installed inside the first year, call us before closing if possible. We can coordinate the install to start within days of move-in.

Underwood-Area Reviews

Debra Whisonant

Rated 5 out of 5

Luan and his crew are first rate deck builders. They refurbished and re-supported our old deck and added on additional new decking in a week after all was approved by the city of Lavista.

The only problems were with the composite supplier which Luan handled quickly. Definitely recommend them if you are looking for a new deck or want to update an old one.

Underwood Deck Installation FAQs

Can my Underwood deck really be installed in 3 days?

For ground-level or low-elevation installs under 350 sq ft, yes. For walkout-basement, multi-level, or wraparound installs, plan on 5 to 7 working days. End-to-end (consultation through final inspection) runs 5 to 8 weeks regardless of size, mostly waiting on permit approval and material delivery.

What's the difference between deck installation and deck building?

Functionally similar work. “Installation” emphasizes the on-site assembly and finish. “Building” emphasizes the upstream design and engineering. We do both. If you already know what you want installed, this is the right page. If you want help designing from scratch, our deck building page is the better start.

What's the most popular decking material installed in Underwood?

Capped composite (TimberTech AZEK and Trex) accounts for around 70% of our Underwood installs. The remaining 30% splits between pressure-treated pine for budget-driven projects and cedar for homeowners who want natural wood with better rot resistance.

Do I need to be home during the install?

Helpful but not required. We need access to the work area, electricity for tools, and a place to stage materials. Most homeowners come and go during the day. We coordinate any decisions that come up by phone if you’re not on site.

Do you install on new construction homes before move-in?

Yes, if the home’s certificate of occupancy is in place and we can access the property. Coordinating the install to start within a week of your closing date is straightforward. Call us before closing if you want to lock in a slot.

What permits do I need for an Underwood install?

Pottawattamie County requires a building permit for all deck installation work. We pull the permit in our name as part of every project, file the structural drawings, and coordinate the three required inspections (footing, framing, final).

Can you install a deck on a Loess Hills sloped lot?

Yes. Hillside installs require deeper, often wider footings, additional lateral bracing, and code-compliant railing on the high side. We engineer the post heights and stair geometry around the actual slope.

Do you install lighting and other add-ons during the deck install?

Yes. Low-voltage post-cap lights, riser lights, and surface dot lights install during the deck build itself. Adding them after the fact costs more because we’re working around finished decking. If you want lighting, decide before crew start.

How quickly can you get on site?

Spring slots typically book 6 to 8 weeks ahead. Summer, fall, and winter availability runs 3 to 4 weeks out. Call (402) 369-5724 for current scheduling.

(takes 1-2 min)

Underwood is a Pottawattamie County town of just under 1,000 residents at I-80 exit 17, roughly 10 miles northeast of Council Bluffs. The community is anchored by Underwood Community Schools (home of the Eagles), Trailhead Park, and a long-running Fourth of July parade. New subdivisions along the ridgeline north and east of town have driven steady residential growth, and most of those new homes want a deck within the first year of move-in. We install regularly across the original townsite, the newer Eagle Ridge developments, and the rural acreages out toward Hitchcock Nature Center.
