How we build a deck
Six stages, in this order, on every job. Nothing here is optional and nothing here is a surprise line item later.
1. Measure and design
We come out, measure the house, check door threshold heights and the fall across the yard, and find out where the gas meter, the hose bib and the dryer vent sit. Then we talk through what you actually want to do out there, and come back with two or three layouts at different prices. See deck design for what that covers.
2. Written scope
Materials by brand and product line, framing specification, hardware, railing style, stair count, timeline and price. Anything that changes afterwards gets written down before we do it. No verbal change orders.
3. Permit
We prepare the framing plan and submit it to whichever jurisdiction your property sits in. Permits work a little differently in each city, and some rely on the county or a neighbouring city, so turnaround varies. We tell you which offices you are dealing with.
4. Footings and posts
Holes dug below the frost line, inspected before anything is poured, then filled with concrete and fitted with a galvanised standoff post base so end grain never sits in standing water. On the clay that runs through much of this area, footings sometimes need to be wider than the minimum to spread the load.
5. Ledger, frame and deck
The ledger is through bolted or structurally screwed at the spacing the span requires, then flashed with a metal cap and a self adhering membrane. Every joist and beam gets butyl joist tape on the top edge. Joists are spaced for the decking product going on top, which for composite is tighter than most people expect. Boards go down with hidden fasteners, guards are built to current code, and stairs get a consistent rise across every step.
6. Inspection and handover
We meet the inspector, get the card signed, and hand you the paperwork with the product warranties. The permit record follows the house.
How to read a deck quote
Deck quotes for the same yard routinely come back thousands of dollars apart, and it is almost never because one builder found efficiencies. It is because they are quoting different decks. Three line items explain most of the spread, and none of them are visible once the deck is finished.
Ask for the footing depth
A quote that assumes concrete deck blocks sitting on the surface will always beat one that pours footings below the frost line. It will also be the deck that goes out of level within five winters. Get the depth written on the quote.
Ask for the joist spacing
Sixteen inches on centre is standard for a perpendicular composite layout and twelve for a diagonal. Framing at twenty four inches is cheaper, produces a deck that feels bouncy, and voids the board warranty you paid extra for.
Ask how the guard posts attach
A guard post bolted to the rim joist or to blocking inside the frame will take the load code expects. A guard post screwed down through the decking is holding on with a few fasteners in a board, and you can feel the difference by pushing on the rail. Blocking has to go in during framing, so this is decided before the boards are down.
Then compare
With those three items written on every quote, most of the spread explains itself, and you are comparing the same deck rather than the same square footage. If a builder will not put them in writing, that is the answer to a different question.
Building for Ohio conditions
Four things about this climate change how a deck has to be built, and all four are why decks built to a generic national spec fail early here.
Freeze and thaw
Between November and March the ground freezes, lifts and settles repeatedly. A footing that stops above the frost line gets pushed up and does not come back down level. This is why deck blocks and shallow piers fail here even though they work in warmer states.
Water in every month
Dayton gets meaningful rain year round. Wood that stays wet rots, and composite sitting in trapped water grows surface mould underneath. Board gaps, ventilation under the deck and grading that moves water away all matter more here than in a dry climate.
Real summer UV
South and west facing decks take serious sun through July and August. Wood greys out if it is not sealed. Dark composite gets hot enough underfoot to be unpleasant by mid afternoon. We flag which way your deck faces before you pick a colour, not after the boards are down.
Clay soil
Much of the area sits on clay, which holds water and carries less load per square foot than granular soil. Footings sometimes need to be wider than code minimum. It costs a little more concrete and it is not optional.

Why homeowners pick Dayton Custom Decks
Footings below the frost line
Ohio ground heaves. Every post we set lands on a poured footing below the local frost depth, which is what keeps a deck level through a decade of freeze and thaw.
Permits and inspections handled
We pull the permit, meet the inspector and hand you the signed card. An unpermitted deck becomes your problem the day you sell the house.
Written scope before we start
Materials, framing spec, hardware, timeline and price in writing before anybody swings a hammer. No verbal change orders.
Where we build
We work across Dayton and the Miami Valley. Each community below sits in a different permit jurisdiction and has its own housing stock, which changes what makes sense out the back.

FAQ
How much does a deck cost in Dayton, OH?
A 320 square foot elevated deck in pressure treated pine typically plans out at roughly 11,500 to 18,000 dollars installed in the Dayton area, and the same deck in capped composite at roughly 19,000 to 29,000. All in, expect about 36 to 56 dollars per square foot for treated and 59 to 91 for composite, including footings, framing, decking, railings and stairs. Ground level decks under 30 inches come in lower because no guard rail is required.
Do I need a permit to build a deck in Dayton?
For an attached deck, yes. Each city handles permits a little differently, and some rely on the county or a neighbouring city. Ohio only waives the state permit for a deck that is detached, 200 square feet or less, no more than 30 inches above grade and not serving a required exit door, and most of these cities still want a zoning or HOA sign-off even then. We prepare the framing plan, submit it, and meet the inspector at footing and at final. An unpermitted deck can come up in a buyer's inspection or a records check and becomes a problem when you sell.
How long does a deck take to build?
A straightforward 200 to 300 square foot deck is framed, decked and railed in four to six working days once we start. The longer part is ahead of that. Permit turnaround runs one to three weeks depending on the jurisdiction, and composite decking sometimes carries a lead time, so first call to finished deck is usually six to twelve weeks. You get a realistic window in writing before you commit.
What should be in a deck contract before I pay a deposit?
A fixed scope, not a one line summary. It should state the footing depth, joist spacing, decking brand and line, railing type, stair count, what is included for demo and disposal, the permit responsibility, the payment schedule and how change orders are priced. A deposit should be modest and tied to material ordering, never most of the job up front, and the contractor should carry liability insurance and workers compensation. If all of that is in writing, the two most common deck complaints, surprise change orders and abandoned jobs, mostly stop being possible.
Composite or wood?
Composite if nobody in the household is going to seal a wood deck every two to three years, which is the most reliable predictor of how a deck looks in year eight. Wood if the budget is the binding constraint, if you genuinely prefer real grain, or if the house is old enough that composite would look wrong on it. Composite costs roughly 60 to 90 percent more up front and close to nothing after.
How deep do deck footings go in Ohio?
Below the frost line. Each building department sets its own depth, around Dayton it is commonly 32 inches, and we confirm the local figure at the estimate. We pour concrete footings sized for the load each post carries and set the post on a galvanised standoff base so end grain never sits in water. Deck blocks resting on the surface are the single most common failure we are called out to fix, because the ground here lifts every winter.
Can you work on my existing deck instead of replacing it?
Often, and the frame decides. If the posts, beams, joists and ledger are sound, replacing the surface and railings costs roughly a third of a full rebuild and buys another fifteen years. If the deck sits on surface blocks or the ledger was nailed on, repair is money spent on something that still has to come out. We tell you which one you have before you pay us anything.
What happens if the crew doesn't show up, or the job goes quiet mid build?
That is the complaint we hear most about other contractors, and it usually happens because a crew is booked on two or three jobs at once and yours is not the one they show up for that week. Once your build starts, it is the only job that crew is on until it is finished. You get a start date in writing, and if weather or an inspection pushes it, you hear that from us before the day it was supposed to happen, not after.
What areas do you cover?
Dayton Custom Decks works across Dayton and the Miami Valley, including Oakwood, Kettering, Centerville, Beavercreek and Springboro. Each of those sits in a different permit jurisdiction, and we handle whichever one applies to your property.
Is the estimate really free?
Yes. We come out, measure, look at the door heights and the access route, and talk through what you want to do. You get two or three layout options with prices and a written scope covering materials, framing spec, hardware, timeline and price. There is no charge and no obligation.
