Outdoor rooms built for Georgia summers.
Composite and wood decks, screened porches, and 3- and 4-season rooms across metro Atlanta, engineered for our climate and backed by a free, detailed estimate.
Decks & Porches in Metro Atlanta
A deck or porch in metro Atlanta has to do more than look good; it has to hold up to humid summers, sudden storms, and the freeze-thaw swings that loosen fasteners over time. JMJ Construction Group designs and builds decks, screened porches, and three- and four-season rooms across Atlanta, engineering each one for how Georgia's weather actually behaves.
As a licensed Georgia general contractor, we get the structure right where it counts, footings sized for our clay soil, properly flashed ledger connections, and code-compliant railings, then finish it to match your home. Many deck clients come back later for a home addition or bathroom remodel because the same crew and the same standard are carried across the whole property.

Composite and wood decks
Most metro Atlanta homeowners choose between composite decking (Trex, TimberTech, and similar) and traditional pressure-treated or cedar. Composite costs more up front but shrugs off Georgia humidity with almost no maintenance, while a wood deck costs less and offers a classic look that needs regular sealing. We build both, with concealed fasteners, correct joist spacing, and flashing that keeps water out of the structure.
Whether it is a simple ground-level deck or a multi-level, elevated deck on a sloped lot, the deck installation is only as good as what holds it up — so we never cut corners on footings, ledger attachment, or post connections.
- Composite decking (Trex, TimberTech) and PVC boards
- Pressure-treated and cedar wood decks
- Multi-level and elevated decks for sloped lots
- Integrated lighting, railings, and built-in seating
Screened porches and covered outdoor living
A screened porch is the single best upgrade for actually using your outdoor space in a Georgia summer — it keeps mosquitoes and pollen out while letting the breeze through. We build new screened and covered porches and porch conversions, and we can screen in or roof an existing deck.
For homeowners who want to cook and entertain outside, we integrate outdoor kitchens, fireplaces, and lighting into the porch design so the finished space works day and night.
- Screened-in porches and porch conversions
- Covered porches and porch roofs
- Outdoor kitchens, fireplaces, and lighting
- Repairs to existing decks, railings, and rotted framing
Three-season and four-season rooms
A three-season room is an enclosed porch with screens and windows you can enjoy from spring through fall, but it is not heated or cooled. A four-season room is fully insulated and tied into your home's HVAC, so it lives like a true home addition you can use year-round. We build both, and we will walk you through which one fits your home and how you plan to use it.

What goes into a deck or porch project
A few factors move every deck and porch project. Knowing them up front makes your estimate easy to understand.
- Material choice: composite costs more up front but saves on maintenance; wood is the opposite
- Size, height, and levels: elevated and multi-level decks need more structure and labor
- Add-ons: screening, roofing, lighting, and built-in seating each expand the scope
- Site access and grade: sloped or hard-to-reach lots take more prep
- Permits and inspections: most Atlanta-area decks require them, and we handle the process

Answers before you commit
How much does it cost to build a deck in Atlanta?
It depends on the size, material, height, and add-ons like roofing or screening; a basic wood deck and a large composite deck or four-season room sit at very different price points. Rather than quoting a generic figure, we review your specific project and provide a free, itemized estimate so you know the exact amount before any work begins.
Do I need a permit to build a deck in Georgia?
In most metro Atlanta jurisdictions, yes, decks attached to the home or above a certain height require a permit and inspection. As a licensed Georgia general contractor, we pull the permits and manage inspections as part of your project.
Composite or wood — which is better in Georgia?
For our climate, composite resists humidity, rot, and fading with minimal upkeep, which is why many homeowners choose it despite the higher upfront cost. Wood costs less initially and looks classic, but needs regular sealing. We'll walk you through the trade-offs for your budget and how long you plan to stay.
Can you screen in or add a roof to my existing deck?
Yes. If your existing deck structure is sound, we can add screening, a roof, or convert it into a three- or four-season room. If it needs reinforcement first, we'll flag that during the assessment. Larger conversions often overlap with our home additions work.
Are you licensed and insured?
Yes. JMJ Construction Group holds a Georgia general contractor license (GCI000260) and a business license (CON001716), and carries liability coverage through Next Insurance. We can provide proof of both before your project begins.
Do you offer free estimates?
Always. We'll assess your site, talk through materials, and provide a detailed written estimate at no cost and no obligation.
