A deck installation looks simple from the outside. A crew shows up, lumber appears in the driveway, a few weeks later you’ve got a finished deck. From the homeowner’s perspective, what happens in between can feel like a black box, especially if you’ve never been through the process before.
The reality is that a well-run deck project follows a predictable rhythm. Knowing what each phase actually involves, how long it takes, and what you should expect to see (or not see) helps you stay informed without micromanaging, spot problems early when they’re easy to address, and make decisions confidently when questions come up mid-project.
This walkthrough covers what a typical deck installation looks like in Apple Valley from the day you sign the contract through final inspection, with a realistic timeline and a clear sense of what’s happening at each stage.
A Note on Timelines Before We Start
Every project is different. A simple rectangular deck on a flat lot moves faster than a multi-level deck with custom features on a sloped property. Weather affects timelines in Minnesota more than almost anywhere else, especially in spring and fall when freeze events can pause work. Permit processing speeds vary with the season and with how busy the building department is
The week-by-week structure below assumes a moderately complex project with reasonable weather and a builder who has the right crew and material availability. Your specific project might compress some phases or stretch others. The shape of the process, though, stays mostly consistent
Pre-Construction: Design Finalization and Permitting (Weeks 1 to 3)
This is the phase that happens before any work appears at your house, and it’s where a lot of the project’s success gets determined
Final design sign-off If your design has been in development through a series of consultations, this is when everything gets locked in. Layout, dimensions, material selections, railing system, lighting plan, accessories. Once this is approved, changes become more expensive because materials get ordered and plans get submitted for permits
Permit application Apple Valley deck permits go through the City of Apple Valley building department. The application requires detailed plans showing the deck’s structural design, attachment to the house, footing locations and depths, railing specifications, and stair details. A good builder handles this on your behalf, but the timeline is partly out of their control. Permit processing typically takes anywhere from a few business days to a few weeks depending on department workload
Material ordering Once permits are submitted (or in some cases approved), material orders get placed. Composite and PVC decking often have lead times of one to four weeks depending on the specific product and color. Railing systems, especially specialized ones like cable or glass, can have longer lead times. Ordering happens early specifically so materials arrive when the crew is ready for them
Utility marking Before any digging happens, you’re required to have underground utilities marked. In Minnesota this means calling Gopher State One Call. Your builder coordinates this, but the marking itself takes a few business days to be completed. Marks are typically valid for a limited time, so the marking call gets timed to the start of construction
What you’ll see during this phase Honestly, not much at your house. Most of the activity is happening in the builder’s office, at the city, and at the suppliers. This phase can feel slow if you’re excited to see progress, but it’s setting up everything that follows. Skipping or rushing it is the most common reason projects later run into problems
Week 1: Site Preparation and Footings
Once permits are issued, materials are scheduled, and utilities are marked, the visible work begins
Day 1 to 2: Layout and demolition If you’re replacing an existing deck, demolition happens first. The crew removes the old deck and disposes of the materials. For a new deck on an undeveloped area, this phase involves carefully laying out the deck’s footprint, marking footing locations, and preparing the ground
Day 2 to 4: Footing excavation Holes are dug for the concrete footings that will support the deck’s posts. In Apple Valley, footings must extend below the frost line, which means digging to a minimum of 42 inches (often deeper depending on soil conditions and the specific design). This is one of the most important steps in any deck installation. Inadequate footings cause frost heave issues that destroy decks over time
Day 4 to 5: Footing inspection and pour Most municipalities require an inspection of the footing holes before concrete is poured. Once the inspector signs off, footings are poured. Concrete needs time to cure, though modern mixes and the use of footing forms means structures can often be built relatively soon after pouring
What you’ll see during this phase A lot of noise and activity, holes in your yard, a concrete truck or pump truck, and what looks like more disruption than progress. By the end of this week, the deck doesn’t look like a deck yet, but the foundation that makes everything else possible is in place
Common questions during this phase
- Why are the holes so deep?
Frost line requirements in Minnesota are strict for good reason
- Why does the inspector have to look at empty holes?
Because once concrete is poured, the depth and condition can’t be verified without destroying the work
- How long does the concrete need to cure?
Modern mixes allow framing to begin in 1 to 3 days, though full structural strength takes longer
Week 2: Framing and Ledger Installation
With footings in place, the structural skeleton of the deck goes up
Ledger attachment The ledger board (the framing member that attaches the deck to your house) gets installed first. This is the single most critical structural connection on the deck, and it involves more than just bolting a board to the wall. Flashing gets integrated with the existing siding water management. Lag bolts or through-bolts get placed at engineered spacing into the structural framing of the house. Lateral load connectors get installed to provide redundant attachment
Post and beam installation Posts get set into their post bases on the footings. Beams get installed across the tops of the posts. These structural members carry the deck’s load to the footings and need to be perfectly level and properly connected with engineered hardware
Joist installation Joists get hung between the ledger and the outer beams using joist hangers. Spacing depends on the decking material you’ve chosen. Most modern composite and PVC products require 12-inch on-center spacing rather than the older 16-inch standard
Mid-project inspection Most Apple Valley deck projects require a framing inspection before decking goes on. The inspector verifies that the structural design matches the approved plans, that hardware is installed correctly, and that the ledger attachment meets code
What you’ll see during this phase The deck starts to look like a deck. The frame goes up quickly once footings are set, and the structure becomes visible in a way that helps you see how the finished space will feel. This is also when any layout questions or last-minute adjustments become harder to make, so walking the framed structure with your builder is worth doing if anything looks different from what you expected
Week 3: Decking, Railing, and Detail Work
With the structure framed and inspected, the visible deck goes together
Decking installation The decking boards get installed across the joists. Depending on the material and fastening system, this can take 1 to 4 days for an average deck. Hidden fastener systems take longer than face-screwed installations but produce a cleaner finished surface. Picture-frame edge details, inlays, or custom patterns add time
Railing installation Railing posts get installed (often as part of the framing phase to ensure proper structural attachment), and the railing infill (pickets, cable, glass panels, or whatever system you’ve chosen) goes in. Quality railing installation matters for both safety and appearance. This is one of the most visible parts of the finished deck
Stair construction Stairs get built once the deck surface is complete. Stringers get cut, treads get installed, handrails get attached. Apple Valley code has specific requirements for stair geometry, handrail height, and graspability that affect how stairs are built
Trim, fascia, and detail work The edges of the deck get finished with fascia boards or trim that hide the framing and create a clean visual line. Skirting (if your design includes it) goes on. Lighting gets installed and wired
What you’ll see during this phase Rapid visual progress. The deck transforms from a frame to a finished structure in a week or less, and most of what makes the deck look like a deck happens in this phase. This is also when material decisions you made months earlier finally show up in person, and occasionally homeowners realize a color or product looks different than they expected. Catching this early lets adjustments happen, though it’s much easier to avoid by reviewing physical samples during the design phase
Week 4: Final Details, Cleanup, and Inspection
The last week of the project handles the finishing touches and the official sign-offs
Punch list completion Every project has small items that get caught during a final walk-through. Touch-ups, minor adjustments, missed details. A good builder works through these systematically before considering the project complete
Final cleanup Construction debris gets hauled away. The site gets cleaned. Landscaping that was disturbed during construction gets restored as much as possible (though full landscape restoration is sometimes a separate project depending on the scope)
Final inspection Apple Valley requires a final inspection before the deck can be officially closed out. The inspector verifies that everything meets code, including structural elements, railing height and baluster spacing, stair geometry, and any electrical work for lighting
Homeowner walk-through Your builder should walk the finished deck with you, explain maintenance requirements for the specific materials installed, hand over warranty documentation, and answer any final questions. This is when the project officially transitions from a construction site to your finished outdoor space
What you’ll see during this phase A lot less crew activity, but a lot of finishing detail. The deck looks finished by the start of this week, but the difference between “finished” and “finished well” happens in these final days
Apple Valley-Specific Considerations Throughout
A few things worth keeping in mind for any deck installation in this area
Weather windows Minnesota’s construction season has hard edges. Spring projects can get delayed by late freezes and wet ground conditions. Fall projects can get squeezed by early snow. The most reliable construction windows are typically late spring through early fall, and scheduling early in the year often gets you into a better window than scheduling reactively
Frost protection Anything that involves concrete (footings, in some cases stairs and patios) is sensitive to freezing temperatures during curing. Cold-weather concrete practices exist but add time and cost. This is why winter deck installation is uncommon in Apple Valley unless conditions are unusually mild
Permit and inspection timing The city’s permit and inspection availability varies seasonally. Spring tends to be the busiest period, and scheduling around inspector availability sometimes adds days to projects during peak season
Material acclimation Composite and PVC decking products perform best when allowed to acclimate to outdoor conditions before installation. This is part of why material delivery timing matters and why pushing a project to begin “the day materials arrive” sometimes hurts long-term performance
What a Good Builder Communicates Throughout
Across all four phases, the difference between a smooth project and a frustrating one is usually communication. A good builder will
- Set expectations early about realistic timelines, including weather contingencies
- Notify you in advance when crews will and won’t be on site
- Explain inspections when they happen and what they verified
- Flag any unexpected findings (rotted band joist behind the siding, unexpected utilities, soil conditions) immediately rather than letting them turn into surprises later
- Walk you through significant phases as they’re completed so you can ask questions while changes are still easy
If your builder isn’t communicating proactively at each of these stages, that’s worth raising directly. Quiet doesn’t always mean problems, but it’s usually a sign the project is being run reactively rather than proactively.
Ready for a Deck Installation That Runs the Way It Should?
A deck installation is a meaningful investment, and the process matters almost as much as the finished product. A project run well feels organized, predictable, and clear from start to finish. A project run poorly feels like a series of surprises.
