Deck Building in Underwood, IA
A Deck Bros build in Underwood means three things: a custom design drawn for your specific lot, a fixed-price quote you can hold us to, and a finished deck that’s still flat, square, and stain-free a decade from now.
We’re a licensed Omaha contractor building across western Iowa since 2008, and Underwood is one of our regular service stops.

Underwood Lots Aren't Like Other Iowa Lots
If you live in Underwood, you already know your yard isn’t flat. The town sits on the eastern shoulder of the Loess Hills, the only formation of its kind anywhere in the western hemisphere outside of central China. The soil under your house is fine, dry silt that the wind carried in after the last Ice Age. It compacts well when it’s dry. It moves when it’s wet. And it usually drops eight to fifteen feet of grade across a single suburban lot.
That changes how a deck has to be built here. A few things we do specifically for Underwood properties that builders from outside the region tend to skip:
- We read the slope before we draw the design. A site visit isn't just for measuring the back wall of the house. We walk the property line, check where surface water moves during storms, and identify any ridges or terrace breaks that affect post placement.
- Footings get sized for the soil they're going into, not by default. Loess silt is unusual structurally. A 12-inch sonotube might be fine on a flat, dry lot. On a sloped lot at the western edge of town, we'll often spec wider, deeper footings or pour concrete piers with bell-shaped bases for added bearing surface.
- We anchor for the lateral pressure. Hillside decks experience load the same way a retaining wall does. Our framing includes diagonal knee bracing, beam-to-post hardware rated for the load (usually Simpson Strong-Tie connectors), and post bases bolted into the concrete rather than buried in the dirt.
- Drainage gets designed in. Where the deck attaches to your home, water management isn't optional. We install metal flashing behind the ledger, lap it correctly into the house wrap, and tape every joist top so water doesn't sit on the framing for the next thirty years.

Your Underwood Build, by the Numbers
| What | Range |
|---|---|
| Project Size | 250 to 600 square feet |
| Total Investment | $12,000 to $28,000 (most land $16K to $22K) |
| Per Square Foot, All In | $30 (basic pressure-treated, ground level) to $80 (multi-tier composite, hillside) |
| Time on Site | 4 to 10 working days |
| Calendar Time, First Call to Walkthrough | 5 to 8 weeks |
| Permit Lead Time (Pottawattamie County) | 5 to 10 business days |
| Material Lead Time | 1 to 3 weeks |
| Workmanship Warranty | 5 years (transferable to next homeowner) |
The biggest cost variable on Underwood builds isn’t the deck size but the height off grade. A walkout-basement deck twelve feet above the patio takes roughly 30% more labor and 20% more material than the same square footage at ground level. Stairs, taller posts, deeper footings, and code-required guardrails all add up.
The second biggest variable is your decking surface. Pressure-treated pine sits at the bottom of the price band. Capped composite (we install TimberTech AZEK and Trex) sits at the top. Cedar and tropical hardwoods land in the middle.
Choosing What You'll Walk On
- Pick capped composite if you don't want to think about your deck again. No staining, no sealing, no splinters, and no rotted boards. Pay more up front and save the weekends. Typical lifespan in Iowa is 25 to 30 years, with manufacturer warranties up to 50 years.
- Pick pressure-treated pine if budget is the deciding factor or you enjoy the look and upkeep of natural wood. Plan on annual sealing. With proper care, expect a lifespan of 15 to 20 years.
- Pick cedar or hardwood if you want a premium natural appearance and are willing to oil it every year or two. The grain on high-end ipe is especially distinctive. Typical lifespan is 20 to 30 years depending on maintenance.
What Happens After You Call
Day 1: You call or fill out the form. Within a few hours someone from our team gets back to you. We ask three or four basic questions and get a consultation on the calendar, usually within the next 5 to 7 days.
Day 5–7: The owner or a senior estimator drives to your house. We measure the back of your home, walk your yard, talk through how you’ll actually use the deck (grilling, hot tub, dining, kids), and check for utilities, access, and slope. This visit takes about an hour. There’s no charge and no obligation.
Day 10–12: Your design and quote land in your inbox. Written design package, dimensioned drawings, material specs, line-item pricing, and a fixed-price total. For builds over $15,000, you get a 3D rendering. The price you sign is the price you pay. There are no surprises and no change-order ambushes unless you actually request changes.
Week 2: We file the permit. Pottawattamie County turns deck permits around in about a week. We handle the application, site plan, structural drawings, and load calculations.
Week 3–5: Materials get ordered and delivered. Composite has a longer lead time than pressure-treated. We coordinate so the delivery truck shows up the day before the crew starts.
Build week: Crew arrives at the start time we promised. Footing inspection happens before concrete pours. Framing inspection happens before decking goes down. Final inspection closes the permit out. We coordinate every visit with the inspector at (712) 328-5847.
Final day: Walkthrough and warranty handoff. We show you the finished build, explain how to clean and maintain it, hand off the paperwork, and haul every piece of debris off your property. Most Underwood homeowners are eating dinner on the new deck the following weekend.
Permits and the Pottawattamie County Side of Things
Building a deck in Underwood requires a permit. Pottawattamie County requires it for any new deck construction or for reconstruction work that changes the footprint or structural members. We handle this entirely on your behalf, but here’s the short version of what’s involved so you’re not flying blind.
You need: a completed building permit application, a site plan showing setbacks, a structural drawing showing joist sizes and footing depths, and inspections at three points (footing, framing, final). The application goes through the county’s Citizenserve online portal.
A few Underwood-specific items worth flagging:
- If your property falls within the A-4 Loess Hills Zoning District, setbacks and grading rules are stricter. We verify your zoning before drawing the design.
- If the build involves moving more than 50 cubic yards of soil, a separate grading permit is required. Most decks don't trigger this, but aggressive hillside builds can.
- The county adopts the 2015 Iowa Residential Code. Our framing meets or exceeds it.
- Frost protection on footings is non-negotiable in this climate. The Iowa frost line averages 58 inches statewide, and our standard is to pour to at least 42 inches with deeper footings on sloped sites.
Permit fees are baked into your written quote. You don’t write a separate check at the end.

What Underwood Homeowners Tell Us

Debra Whisonant
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 is a Pottawattamie County town of just under 1,000 people, sitting roughly 10 miles northeast of Council Bluffs at exit 17 off I-80. The town traces its founding to the arrival of the Chicago, Rock Island and Pacific Railroad in 1869 and has grown into a popular bedroom community for families working in the Omaha-Council Bluffs metro. The Underwood Community School District (home of the Eagles) anchors the community, the annual Fourth of July parade pulls crowds from across the county, and Hitchcock Nature Center just to the south offers some of the best Loess Hills hiking in the region.
