A deck is a structure, and the parts that decide how long it lasts are the parts nobody sees: footings, ledger attachment, flashing, joist hangers and fasteners. Many decks on Duluth homes are now twenty to thirty years old, which is right at the end of a pressure-treated deck’s comfortable service life, and the failures almost always start at the connection to the house. Luma House builds decks from the footings up and is direct about when a deck should be repaired versus replaced.
What this service covers
- New deck design and construction, including multi-level layouts and landings
- Full replacement of decks that have reached the end of their service life
- Composite, PVC and hardwood decking, and pressure-treated or steel framing
- Footings sized and placed for the span and the soil, with proper depth
- Ledger attachment and flashing where the deck meets the house, which is the most safety-critical detail in the whole structure
- Railings in wood, composite, metal and cable, meeting required height and infill spacing
- Stairs, stringers and handrails, including code-compliant rise and run
- Lighting, privacy screening, built-in benches and under-deck drainage or storage
- Screening or roofing an existing deck where the structure can carry it
Problems Duluth homeowners bring us
Deck calls fall into two groups: it is unsafe, or it is too small.
- Soft or splintering boards and visible rot at the joists or the stair stringers
- A deck that moves underfoot, which usually means fastening or footing problems
- A ledger bolted to the house with the wrong fasteners or no flashing, which eventually damages the rim joist behind it
- Railings that are loose, too low, or spaced wide enough to be a hazard for children
- A deck too narrow to hold furniture, so the space is a walkway rather than a room
- No shade, no screening, and therefore very little use
Planning the project
Decks are permitted structural work and we plan them that way.
- Measure the space against the furniture it actually has to hold, not against the existing deck
- Decide covered, screened or open, since that decides the framing and the footings
- Establish where footings can go, allowing for utilities, grade and drainage
- Inspect the house rim joist and plan the ledger attachment and flashing detail
- Select decking and railing early; both have lead times and both change the framing layout
- Confirm permits and plan for footing and framing inspections
- Agree a written scope, schedule and change-order process
What drives the budget
Deck budgets are driven by framing and footings as much as by the decking you see. Height above grade changes the footing and post requirements, multiple levels add framing and stairs, and a roof changes the structure entirely. Decking material is the most visible choice and often not the largest line. For scale, the 2025 Atlanta-market average for a composite deck addition is about $25,000, recouping roughly 81 percent at resale, among the better recoup figures in that survey.

| Factor | Lower-cost end | Higher-cost end |
|---|---|---|
| Layout | Same footprint, fixtures stay put | Walls, plumbing or venting move |
| Structure | No structural changes | Beams, foundations or roof tie-ins |
| Finishes | Stock or semi-custom selections | Custom cabinetry, natural stone |
| Systems | Existing electrical and HVAC are adequate | Panel upgrades, new circuits, ductwork |
| Permits and HOA | Cosmetic work, no review | Permits, inspections and HOA approval |
Timeline factors
- Permit review and footing inspection before framing can proceed
- Rain and ground conditions during excavation and concrete work
- Concrete cure before framing loads are applied
- Decking and railing lead times, which vary by product and colour
- Framing inspection before decking is installed, which cannot be skipped
- Any repair discovered at the house rim joist once the old ledger is removed
Design considerations
- Depth, because a deck narrower than about twelve feet struggles to hold a table and a chair with a walkway behind it
- Where the door is and how traffic crosses the space
- Railing choice against the view: cable and metal infill preserve it, wide wood balusters do not
- Stair position, which should serve the yard rather than default to the nearest corner
- Decking colour and heat gain, which matters on an unshaded southern or western exposure
- Whether the framing should be built now to carry a future roof or screen enclosure
Permits and local review
| If your home is in… | Permits usually come from | Good to know |
|---|---|---|
| Inside Duluth city limits | City of Duluth Community Development & Engineering | The city runs its own permits, applications and inspections |
| Unincorporated Gwinnett County | Gwinnett County | Many addresses with a Duluth mailing address sit outside city limits |
| Johns Creek, Suwanee, Berkeley Lake, Norcross or Peachtree Corners | That city’s own permit office | Each city sets its own submittal steps |
Always confirm the permitting office for your exact address; city limits do not follow ZIP codes.
How the work runs
| Step | What happens | What you receive | Decisions you make |

| 2. Design and scope development | Layout, selections, structural and permit review | Written, line-item estimate and schedule | Finishes, allowances and phasing |
| 3. Construction | Permits, demolition, rough-ins, inspections, finishes | Regular progress updates; change orders in writing | Approve any change before work proceeds |
| 4. Punch list and walkthrough | Final details, cleaning and walkthrough | Signed punch list and care documents | Sign-off when items are complete |

Frequently asked questions
Do I need a permit to build a deck in Duluth?
Decks are structural and are generally permitted and inspected, with footing and framing inspections before the decking goes on. Whether the City of Duluth or Gwinnett County reviews your address depends on city limits.
Should I repair or replace an older deck?
If the framing, ledger and footings are sound, replacing boards and railings can be good value. If there is rot in the joists or stringers, or the ledger was attached without proper fasteners and flashing, replacement is the honest answer.
Composite or wood?
Composite and PVC cost more up front and require far less maintenance, which is why most homeowners here choose them now. Wood costs less initially and needs regular cleaning and sealing. Both are built on the same framing.
Can my existing deck be screened or roofed?
Only if the framing and footings can carry the additional load, which is an engineering question. Many builder-grade decks cannot without reinforcement, and that is worth knowing before you plan around it.
