Monmouth Deck Builder — Deck Building & Installation

Monmouth, home to Western Oregon University, is a small, quiet town where a backyard deck is the natural extension of a close-knit neighborhood. When Monmouth homeowners come to On Top Home Services for deck building, we do something a lot of contractors won't: we hand the work to a deck builder we know and trust — David Culbertson of 360 Custom Construction.


We're a veteran-owned company that has served the Willamette Valley since 2010, and over those years we've learned exactly who does deck installation the right way. For a custom deck in Monmouth, that's 360 Custom Construction. Picture a simple, well-proportioned deck for a first home, or a larger gathering deck for a growing family — a Monmouth deck builder who plans it around your home, your lot, and your budget, and builds it to last.

The Trust Behind Your Monmouth Deck

Most homeowners never really know who's building their deck. In Monmouth, you do. On Top Home Services personally vetted David Culbertson and 360 Custom Construction — Patrick has been on the job with David and knows his standards firsthand. Because that relationship is real, we're comfortable putting the OTHS name on every Monmouth deck 360 Custom Construction builds. When we say a deck builder is trustworthy, it's because we've earned that trust the hard way — together, on the job.

Deck Building Built for Monmouth's Climate and Lots

Oregon decks live a hard life — wet winters, dry summers, and the long soak-and-bake cycle in between. In Monmouth, Monmouth's mostly level, rural-edged lots build cleanly, leaving design freedom for size and shape. That's why the deck builder matters as much as the materials: proper footings, drainage, flashing, and rot-resistant fasteners are what separate a Monmouth deck that lasts twenty years from one that sags in five.


360 Custom Construction builds every Monmouth deck to code and to the Valley's weather — the same standards On Top Home Services demands of every contractor we bring to your door. It's why 360 Custom Construction is the deck contractor we trust with custom deck installation across Monmouth and the surrounding Willamette Valley.

Our Monmouth Deck Installation Process

From first call to finished deck, here's what a Monmouth deck installation looks like:


  • Free consultation: We meet at your Monmouth property to talk through how you'll use the space and assess the site.
  • Custom design: 360 Custom Construction draws up a deck that fits your lot, your home's style, and your budget.
  • Material selection: Choose the right fit for Oregon — pressure-treated lumber, low-maintenance composite, or naturally rot-resistant cedar.
  • Permits handled: We manage the permits and make sure your deck meets Polk County and Monmouth building requirements.
  • Expert construction: David Culbertson's crew builds it with the craftsmanship we vetted them for.
  • Final walkthrough: We review the finished deck with you to be sure it's right.

Deck Materials That Last in Monmouth, Oregon

A good Monmouth deck builder starts with the right material for our climate:


Pressure-treated lumber — the most budget-friendly option; properly treated, it resists rot and insects and can last 20+ years with periodic sealing. A practical pick for Monmouth homes watching the bottom line.


Composite decking — made from recycled materials, it won't rot, splinter, or need staining, and it shrugs off Monmouth's wet winters with only occasional cleaning. Higher up front, lower for life.


Cedar — naturally beautiful and rot-resistant, cedar gives a Monmouth deck a premium, natural look with less maintenance than standard lumber.


360 Custom Construction will walk you through the trade-offs so your Monmouth deck building investment fits both your yard and your budget.

What Deck Building Costs in Monmouth

Most Monmouth homeowners invest between $8,000 and $25,000 for a quality custom deck, depending on size, materials, height, and features. A standard 12x16 deck in good materials typically lands in the $12,000–$16,000 range, including materials, labor, permits, and workmanship warranty.


The biggest cost drivers are square footage, whether you choose wood or composite, and how complex the build is — a ground-level deck is simpler (and cheaper) than an elevated or multi-level deck. On Top Home Services and 360 Custom Construction will give you a clear, honest Monmouth deck installation quote before any work starts — no guessing, no surprises.

I was looking to have a deck built. David contacted me shortly after I made a request. He listened to my request, provided me with options and costs, then walked me through a timeline. The project started on time and ended on time. David was very skilled and approachable, and a pleasure to work with. I highly recommend David. I am very pleased with the final product.

We hired David at 360 Custom Construction to assemble a patio cover. He and his team were friendly and easy to work with, responsive with communication, trustworthy, timely, and respectful of property, cleaning up the work area upon completion. We would highly recommend this company.

David is amazing. He is always on time. He keeps the customer apprised of the progress and any relevant concerns. He is honest, and keeps his customers’ best interest at heart. He is a hard worker. You won’t be disappointed. We were very lucky to have found him.

— Karen Thomas
★★★★★

Our project was on the smaller end of David’s expertise, but we had just purchased our home, I just had surgery, and our house is in Millersburg. David was very patient with us as we discussed the location and size of this door and purchased exactly what we needed. It was installed quickly and expertly and looks great. Our home has a large deck that needs some shade — I still intend to have David back to build us a patio cover. We were very lucky to have found him!

Deck Building in Monmouth, Oregon — Frequently Asked Questions

How much does it cost to build a deck in Monmouth, Oregon?

A ground-level deck of 200–400 sq ft typically runs $3,000–$8,000 for materials and labor in the Monmouth area. Elevated decks with stairs and railings run $8,000–$20,000+. The biggest cost drivers are size, material (composite vs. wood), and whether the deck is ground-level or elevated. Permits add roughly $200–$500 depending on the municipality.

Who actually builds the deck — is it On Top Home Services?

On Top Home Services connects you with David Culbertson of 360 Custom Construction, a personally-vetted deck builder serving Monmouth and the Willamette Valley. OTHS vets and coordinates the project; 360 Custom Construction handles the design and build. You get one trusted point of contact and a builder with a proven track record.

Composite or wood decking — which is better for Monmouth's climate?

Oregon gets 40–60 inches of rain a year, so moisture resistance matters most. Composite is the best overall choice for most Monmouth homeowners: 25–30+ year lifespan, no annual sealing, won't rot or splinter (about $5–$10 per linear foot). Cedar is the best natural-wood option (20–25 years, seal every 2–3 years). Pressure-treated pine is the budget choice ($2–$4 per linear foot) but must be sealed every year to last.

Do I need a permit to build a deck in Monmouth, Oregon?

In Oregon, decks more than 30 inches above grade or over 200 square feet typically require a building permit, and requirements vary by municipality. Your builder handles or guides the Monmouth permitting process as part of the project, so you don't have to navigate it alone.

How long does it take to build a deck in Monmouth?

Most deck projects run 4–8 weeks from first consultation to completion, depending on permit turnaround, deck size, and Oregon weather. 360 Custom Construction walks you through a clear timeline up front and, per repeat customers, starts and finishes on schedule.
