Key takeaways to understand how long does it take to build a deck:
- A typical Colorado Springs deck takes about 4 to 8 weeks from your first design conversation to your final inspection sign-off.
- On-site construction, the actual building part, usually runs 3 to 12 working days once crews break ground.
- Permit review through the Pikes Peak Regional Building Department is the step most homeowners underestimate, and it can quietly add two to three weeks before a hammer ever swings.
- Elevation, frost depth, and Colorado’s freeze-thaw cycles change your schedule in ways a national average never accounts for.
Keep reading, and you will know exactly where your project’s weeks go and how to protect your timeline from the delays that catch most homeowners off guard.
How Long Does It Take to Build a Deck?
Building a standard residential deck takes about 4 to 8 weeks from initial design through final inspection. The physical, on-site construction portion, digging footings, framing, and laying decking, typically takes 3 to 12 working days.
That gap matters more in Colorado Springs than in most cities. Between regional permit review, a 30-inch frost depth requirement, and a construction season that narrows sharply in winter, the “build phase” is often the shortest part of the whole project.
Once your design is locked in, the engineering behind it determines how smoothly the rest of your timeline runs. Genesis Group’s deck-building process folds structural engineering into every plan from day one. See how our deck services work →
What Actually Happens During Each Phase of a Deck Build?
A deck project moves through six distinct phases, and each one has its own rhythm. Some can overlap. Others cannot start until the previous one is fully signed off.
1. Design and Planning: 1 to 3 Weeks
This is where layout, materials, and structural details get finalized. Sloped lots, second-story decks, and multi-level designs all add time here because they need more engineering review before anyone submits paperwork.
- Site measurements and elevation checks
- Material selection (Trex, Fiberon, TimberTech, and similar composite brands are common choices in the Colorado Springs market)
- Structural drawings for permit submission
2. Permit Review: 1 to 3 Weeks
Nearly every deck in El Paso County needs a permit. Decks are explicitly listed as a permitted project by the Pikes Peak Regional Building Department, along with covers, enclosures, and retaining walls over four feet tall.
Typical review takes about two weeks for a straightforward deck plan. Complex structures, second-story decks, or anything needing a variance can take longer.
3. Site Prep and Footings: 2 to 5 Days
Crews clear the build area, dig footing holes, and pour concrete piers. This step is where Colorado’s climate leaves its biggest fingerprint on your schedule, and it deserves its own section below.
Bill Palmer, a licensed engineer and longtime editor-in-chief of Concrete Construction, notes that concrete gains strength quickly in the first week, with moist-cured concrete reaching roughly 50 percent more strength than uncured concrete after 7 days, and full design strength arriving around the 28-day mark. Cold weather slows that process down considerably, which is exactly why footing timelines stretch during a Colorado Springs winter.
4. Framing: 2 to 5 Days
Once footings have cured enough to bear weight, the ledger board, posts, and joists go up. This is the fastest-moving phase on a good-weather week, since it’s mostly carpentry rather than curing time.
5. Decking and Railings: 2 to 5 Days
Boards, stairs, and railings go on last. Composite materials install faster than most natural wood species because there’s no staining or sealing step, though final material choice depends on your budget preferences and the look you want.
6. Final Inspection: 1 to 2 Days
A building inspector confirms the deck meets code before you’re cleared to use it. Scheduling this inspection promptly, rather than letting it sit on a to-do list, is one of the easiest ways to close out a project on time.
How Does Colorado Springs’ Climate Change Your Deck Timeline?
Colorado Springs’ elevation and frost cycle add real time to a deck build that a generic national timeline simply will not show you. Footings here must reach a 30-inch frost depth, deeper excavation than most of the country requires, and cold snaps can pause concrete curing for days at a stretch.
Freeze-thaw cycles are the biggest hidden variable. Water in the soil around a footing expands as it freezes, and a shallow or rushed footing can shift over a single winter. That’s a structural issue, not a cosmetic one, which is why reputable builders won’t rush the footing phase even when a homeowner is eager to finish.
Properties in wildfire-prone areas around Woodland Park face an added layer: some jurisdictions restrict combustible decking materials or require defensible-space clearance before a permit gets approved. If your property sits in one of these zones, build that review into your timeline expectations from the start.
Best Build Windows by Month
| Month | Typical Ground Conditions | Weather Reliability | Best For |
|---|---|---|---|
| March–April | Thawing, often muddy | Variable, spring storms common | Design and permitting, not footings |
| May–June | Stable, workable | High | Footings, framing, full builds |
| July–August | Stable, hot afternoons | High, with monsoon-season afternoon storms | Full builds, early morning crews preferred |
| September–October | Stable, cooling | High | Ideal for footings and framing |
| November–February | Frozen or freeze-thaw | Low | Design and planning only in most years |
Every jurisdiction in the Genesis Group service area handles permitting a little differently. Colorado Springs and Woodland Park fall under the Pikes Peak Regional Building Department, while Castle Rock and Parker answer to Douglas County’s own building department entirely.

What Makes a Deck Project Take Longer Than Expected?
Three factors push a deck timeline past the averages above: size, design complexity, and how thoroughly the project was planned before construction started.
Size of the Deck
Small decks move fast. Large or multi-level decks need more footings, more structural calculations, and more inspection touchpoints.
| Deck Size | Square Footage | Typical On-Site Build Time | Typical Crew Size |
|---|---|---|---|
| Small | Under 200 sq ft | 3 to 6 working days | 2 people |
| Medium | 200 to 400 sq ft | 7 to 10 working days | 2 to 3 people |
| Large or Multi-Level | Over 400 sq ft | 10 to 15 working days | 3 to 4 people |
Deck sizes in this region tend to run larger than the national norm. According to the National Association of Home Builders, the Mountain census division, which includes Colorado, averages 422 square feet per deck on new homes, the largest average of any region in the country. That single fact explains a lot about why Colorado Springs projects often land on the higher end of the size table above.
Design Complexity
Built-in seating, pergola combinations, curved railings, and multi-tier layouts all add engineering hours before construction even starts. None of that shows up in the “days to build” number, but it absolutely shows up in the design and permitting weeks.
How Well the Project Was Planned Upfront
Projects with a finalized design, confirmed materials, and a submitted permit application before construction begins move noticeably faster than projects where decisions get made mid-build. Change orders after framing starts are the single most common cause of a deck running past its original schedule.
A deck is one of the highest-value additions homeowners can make to a Colorado property, and the data backs that up. Genesis Group has written about exactly how strategic upgrades like this pay off. Read Enhancing Home Value →
How Should You Plan Your Deck Before Construction Starts?
The homeowners who move through this process fastest all do the same three things before calling a builder.
Walk the Space at Different Times of Day
Morning shade and afternoon sun patterns should shape where doors, seating, and shade structures go, and the only way to see those patterns is to spend time in the yard before design decisions get locked in.
Decide on Materials Early
Composite, pressure-treated wood, and steel-framed systems all have different lead times, and backorders on popular composite colors can add weeks to a schedule if the decision gets made late in the process.
Think About How the Deck Connects to the Rest of the Yard
A deck rarely stands alone. Planning it alongside your landscaping, even a small side yard, prevents a second round of construction later once the deck is already in place.
If your outdoor space is tight, a deck still has a place in it, it just needs the right layout. Small-yard homeowners face a lot of these same planning questions. Read Landscaping Ideas for Small Yards →
What Should You Look for in a Builder to Protect Your Timeline?
Not every delay comes from weather or permits. Some come from the builder. A few things separate a builder who protects your schedule from one who quietly lets it slip.
- Engineering oversight on every project, even the straightforward ones. Sloped lots and multi-level decks need structural sign-off before a permit will even move forward.
- A team that handles permitting directly, rather than leaving a homeowner to navigate Pikes Peak Regional Building Department paperwork alone.
- Established relationships with material suppliers. A builder who regularly orders Trex, Fiberon, TimberTech, Fortress, or RDI products rarely gets stuck waiting on backordered boards the way a first-time buyer might.
- A finished project history you can actually see, rather than one only described in a sales pitch.
Seeing finished work tells you more about a builder’s timeline habits than any conversation will. Genesis Group’s completed decks and outdoor spaces around Colorado Springs are worth a look before you commit to a design. Browse the Gallery →
Frequently Asked Questions About How Long It Takes to Build a Deck
Can you build a deck in Colorado Springs during winter?
Design work, material selection, and permit submission can all happen in winter. Actual construction, especially footings, is riskier because frozen ground and slow concrete curing make late fall through early spring a poor window for pouring. Most builders schedule winter projects to break ground once the ground has stabilized.
How long does a deck replacement take compared to a brand-new build?
Replacements are often faster because the footings and structural layout may already be usable, pending inspection. A straightforward board-and-railing replacement can sometimes finish in under a week once permitted, while a full teardown-and-rebuild follows the same timeline as new construction.
Do small decks still need a permit in El Paso County?
Most do. The Pikes Peak Regional Building Department requires permits for deck construction regardless of size in most cases, though very small, low, freestanding structures occasionally qualify for exceptions. Confirming this before you build avoids a stop-work order later.
Does composite decking take longer to install than wood?
Not usually. Composite boards often install slightly faster than natural wood because there’s no staining or sealing step afterward. The framing and footing timeline underneath stays the same regardless of which decking material sits on top.
What is the single biggest way to speed up a deck timeline?
Submit a complete, finalized design before applying for your permit. Incomplete plans get sent back for revisions, and that round-trip is one of the most common reasons a “two-week” permit review turns into five or six weeks.
Your Deck Timeline Starts With the Right First Conversation
A deck is one of the more visible investments a Colorado Springs homeowner can make, and the timeline questions homeowners ask are almost always really questions about trust. Will the crew show up when they say they will? Will the footings actually hold through a hard winter? Will the permit process turn into a paperwork maze?
Those are fair questions, and they deserve a builder who answers them with specifics, not reassurances. Genesis Group has built decks and outdoor living spaces across Colorado Springs, Woodland Park, and Castle Rock for more than two decades, with engineering oversight built into every project from the first site visit.
