Who we are
MNZ Construction is a family-run general contractor based at 300 W Waugh Street in Dalton, Georgia. We build across Northwest Georgia — Whitfield, Gordon, Catoosa and Murray counties — and over the state line into the Chattanooga and Cleveland areas of Tennessee.
Roberto owns the business, prices the work and is on the site while it is being built. That is not a marketing line about accessibility; it is a description of how a crew this size actually operates. When you call the number on this website, you reach the person who will stand in your yard and work out where the carport goes. When something needs deciding halfway through, you are not waiting on a project manager with eleven other jobs.
What we build splits roughly in two. Outside, post-frame structures and outdoor living: carports, pole barns, RV covers, pavilions, decks, covered porches and fencing. Inside, remodeling: custom tiled showers, bathrooms, garage conversions and room additions. It is a wide range for a small crew, and the reason it works is that most of it is the same fundamental skill — framing something square, roofing it so water leaves, and finishing it so it looks deliberate.
What our customers actually say
We would rather point at the Google listing than write our own testimonial. As of August 2026 it stands at 5.0 stars across 19 reviews, and what is striking about them is how consistent they are. Almost none of them praise craftsmanship in the abstract. They say the same three things, over and over:
- The price was fair and it held. “He gave me a fair estimate…” — “did an excellent job at a fair price…” — “Fair price. Easy communication.”
- We turned up when we said we would. “showed up when they said they would and got the job completed” — “Did the work when he said he would and to the specifications we agreed upon.”
- We communicated the whole way. “Roberto communicated with us for clarity to ensure we got what we needed.”
There is one review we think about more than the others. A customer describes a supplier delivering poor-quality wood panels, and notes that before she could say anything, Roberto had already sent them back and ordered better ones. She then had us build a covered patio and fence the yard. Getting the second job from the same customer is the only review that really counts.
How we work
The estimate is free and it is a real visit
We come out, walk the ground, measure, and talk through what will actually work on your site — setbacks, slope, drainage, how a new roofline meets the old one. Nobody who quotes a structure over the phone without seeing the ground is giving you a real number.
The price goes in writing before anything is ordered
Scope, materials, sizes and colors named. If you change something, we re-price it before we start rather than after. Where an allowance is genuinely necessary, it is shown as an allowance rather than buried in a lump sum.
We tell you what we find
Rot behind a shower wall, soft decking under an old roof, a deck ledger that was never flashed. Older buildings hide things. You get a photograph and a price before we build back over any of it.
We will talk you out of work
If a roof needs a pipe boot rather than a replacement, we say so and take the smaller job. If a garage should not become a bedroom, we say that too. Selling somebody the wrong job is the fastest way to never hear from them again.
Where we work
The honest limit on our area is how far a truck can get in the morning and still put in a full day. In practice that means Dalton, Tunnel Hill, Rocky Face and the rest of Whitfield County; Ringgold and Fort Oglethorpe in Catoosa County; Calhoun and Gordon County to the south; Chatsworth and Murray County to the east; and across the state line to Chattanooga, East Ridge and Cleveland in Tennessee.
That list is where we work most, not a boundary. If you are near it, call and ask — we will give you a straight answer about whether it is a drive we can make properly, which is more useful to you than a quote we cannot honor. See all service areas.
Common Questions
Ask us directly and we will give you the specifics for your project and your jurisdiction, in writing. Licensing requirements for residential building work differ between Georgia and Tennessee and between the counties we work in, and we would rather answer the question precisely for your job than make a blanket claim on a web page. It is a reasonable thing to ask any contractor, and you should ask it of everyone you get a quote from.
Roberto and our crew. We are deliberately small, which means the people who start your job are the people who finish it, and the person who priced it is on site while it is being built. The trade-off is that we cannot run six jobs at once, so occasionally you will wait a little longer for a start date than a bigger outfit would quote you.
Our work is residential and light building work. Small commercial buildings that need an outbuilding or a straightforward remodel are worth asking about. A commercial fit-out, a large industrial project or volume subdivision work is not what we do, and we would rather tell you that in one phone call than take it on and do it badly.
It varies with the season and with what is in the yard. What we will do is tell you the real answer when you call rather than a comfortable one — including when the wait is on a supplier rather than on us. Truss lead times and roof panel colors are frequently the longest part of a post-frame project, and that part is not something we control.
No. The visit is free, there is no obligation, and there is no charge for hearing that an idea will not work on your site. That last part matters more than it sounds — a fair amount of what we do on an estimate visit is explaining why the spot somebody had in mind is the spot that collects all the water.
Gladly, and it usually saves you money. The crew, the machinery and the material deliveries are already on site, so a deck and a fence, or a roof and the outbuildings, cost considerably less done together than as two visits. If you have a list of things you have been meaning to get done, tell us all of it at the estimate rather than one at a time.
