About JMJ Construction Group

Built on craftsmanship, accountability, and doing right by every client

JMJ Construction Group is a licensed, locally owned general contractor based in Marietta, Georgia. We bring 50+ years of combined experience to home remodeling, additions, and new construction across metro Atlanta, and we treat every project like it carries our name, because it does.

One accountable team, from first call to final walkthrough

JMJ Construction Group was built on a simple idea: a homeowner should be able to hand their project to one team and trust it will be done right. We're locally owned and operated from Marietta, and the same people who quote your project are the ones who build it: no call centers, no rotating crews, no finger-pointing between subcontractors.

Across fifty-plus years of combined experience, our team has built and renovated homes throughout metro Atlanta: kitchens and baths, additions and outdoor living, and ground-up custom homes. We take on projects from $500 repairs to $1M+ custom builds, which means whatever your home needs, you're working with people who have done it before and who stand behind the result.

Our Values

The standard behind every project

We're proudly Christian-owned, and that shows up less in what we say and more in how we work, honestly, and with respect for the people who trust us with their homes.

Integrity

We do what we say we'll do. The scope you approve is the scope we build, and if something changes, you hear it from us first.

Accountability

One team owns your project from first consultation to final walkthrough. When you have a question, you know exactly who to call.

Craftsmanship

We slow down where it counts: the structure, the waterproofing, the details you won't see — so the work holds up for decades, not seasons.

Respect

Your home is where your life happens. We protect it while we work, communicate clearly, and leave it better than we found it.

Why metro Atlanta homeowners choose JMJ

Plenty of contractors can frame a wall. The difference lies in everything around the build: accountability, licensing, communication, and the willingness to answer for the result. Here's what sets JMJ apart.

One accountable team, foundation to finish — We self-perform the core trades and manage the rest, so the standard never slips between phases.
Licensed and fully insured — Georgia GC license GCI000260 and liability coverage through Next Insurance, documented before we start.
Written scope before work begins — A clear, itemized estimate after an on-site visit, so there are no surprise charges and no vague verbal numbers.
Workmanship warranty — We stand behind our work in writing.
Established and accountable — a licensed team with a track record across metro Atlanta, from repairs to million-dollar builds
