If you're planning a renovation in Gwinnett County this year, you're probably asking the same question every homeowner asks: What's this actually going to cost? Between fluctuating material prices, labor shortages, and rising permit fees, getting a straight answer can feel impossible. That's why we put together this guide: real numbers, real insight, and honest advice for homeowners in Lawrenceville, Lilburn, and the surrounding Atlanta metro area.
This isn't a sales pitch. It's a resource designed to help you budget, plan, and avoid the most common (and expensive) mistakes we see when homeowners hire the wrong contractor. Whether you're renovating a kitchen, updating a bathroom, or building a deck, you deserve to know what you're getting into before you sign a contract.
What Renovations Actually Cost in Gwinnett County (2026)
Let's start with the numbers. Costs vary depending on materials, scope, and finishes: but here's what we're seeing in the Lawrenceville and Lilburn area right now.
Kitchen Remodeling
A full kitchen remodel is one of the most requested projects we handle, and it's also one of the most variable in cost. Here's the breakdown:
- Budget-friendly refresh (cosmetic updates, basic appliances, laminate counters): $25,000–$40,000
- Mid-range remodel (semi-custom cabinets, quartz countertops, tile backsplash, new appliances): $60,000–$90,000
- High-end transformation (custom cabinets, stone counters, premium finishes, layout changes, structural work): $100,000–$150,000+
The key driver? Cabinetry. Custom or semi-custom cabinets can account for 30–40% of your total budget. If you're changing the layout: moving plumbing, gas lines, or adding an island: expect engineering and permitting costs to add $5,000–$15,000 depending on complexity.

Bathroom Remodeling
Bathrooms pack a lot of systems into a small space: plumbing, electrical, tile, ventilation: so even modest updates can add up quickly.
- Powder room refresh (new fixtures, tile, vanity): $10,000–$18,000
- Full bathroom remodel (tub-to-shower conversion, tile surround, upgraded vanity, lighting): $25,000–$40,000
- Master suite transformation (double vanity, frameless glass, high-end finishes, expanded footprint): $45,000–$75,000+
Tile work is labor-intensive, and in Gwinnett County, skilled tile installers are booking months out. Expect tile and waterproofing alone to run $3,000–$8,000 for a standard 5×8 bathroom.

Deck Construction
Outdoor living is huge in Georgia, and decks remain one of the best ROI projects for resale and quality of life.
- Pressure-treated wood deck (12×16, basic design): $8,000–$12,000
- Composite deck (low-maintenance, longer lifespan, 12×16): $14,000–$22,000
- Multi-level deck with custom features (built-in seating, pergola, lighting, stairs): $25,000–$45,000+
Material costs have stabilized compared to 2022–2023, but labor and permitting fees in Gwinnett have increased. Factor in roughly 15–20% for engineering, permits, and inspections if your deck is elevated or attached to the home.

5 Red Flags When Hiring a Gwinnett Contractor
Not all contractors are created equal: and in Georgia, the barrier to entry is lower than you'd think. Here are the warning signs that should send you running in the other direction.
1. No State License or Insurance
Georgia requires general contractors to hold a state license for projects over $2,500 or involving structural work. If a contractor says "I don't need one for this job," that's a red flag. Unlicensed contractors can't pull permits, can't get inspections, and leave you holding the bag if something goes wrong.
What to ask: "Can I see your state contractor license and proof of general liability insurance?"
2. They Won't Pull Permits
Some contractors will tell you permits are "optional" or "just paperwork." They're not. In Gwinnett County, permits are required for almost all structural, plumbing, electrical, and HVAC work. Skipping permits means no inspections: and that means hidden code violations that could cost you tens of thousands to fix later (or kill a future home sale).
What to ask: "Will you handle all permits and inspections, or is that my responsibility?"

3. No Engineering Expertise for Structural Work
If your project involves removing walls, adding square footage, or building an elevated deck, you need someone who understands structural loads, footings, and building codes. A contractor without engineering knowledge (or access to a licensed engineer) is guessing: and guesses don't pass inspections.
What to ask: "Do you have in-house engineering expertise, or do you work with a structural engineer?"
4. Vague or Incomplete Contract
A professional contract should include a detailed scope of work, materials list, timeline, payment schedule, and warranty terms. If the contractor hands you a one-page "estimate" and asks for half the money upfront, walk away.
What to ask: "Can you provide a detailed, written contract before we agree to anything?"
5. They Pressure You to Sign Immediately
Legitimate contractors don't need to pressure you. If someone says "this price is only good today" or "we need a deposit right now to lock you in," that's a sales tactic: not a professional relationship.
What to ask yourself: "Do I feel rushed, or do I feel informed?"
Why Design-Build Can Save You 15% (and a Lot of Headaches)
Here's how most renovation projects work: you hire an architect to draw plans, then you hire a general contractor to build them. The problem? Architects design what looks good on paper. Contractors build what's actually feasible and cost-effective. When those two don't communicate well, you end up with change orders, delays, and budget overruns.
Design-build solves that problem. With design-build, the same team handles design and construction. That means the people drawing your plans know exactly what materials cost, what's structurally sound, and what Gwinnett County inspectors will approve. No miscommunication. No "we didn't know it would cost that much." No finger-pointing between architect and contractor.
How Design-Build Saves Money
- Fewer change orders: When the designer and builder are the same team, plans are built around constructability from day one.
- Material efficiency: We source materials in bulk and design around what's available, not what's trendy but back-ordered.
- Faster timelines: No waiting weeks for an architect to revise plans after the contractor says "that won't work."
- Single point of contact: One contract, one team, one phone number. You're not managing multiple vendors.
In our experience, design-build projects typically come in 10–15% under budget compared to traditional architect + general contractor setups: and they finish faster. That's not magic. It's just better coordination.
Caveat: Design-build isn't right for every project. If you're doing a historic renovation with strict architectural requirements, or if you already have detailed plans from a third-party architect, traditional build might make more sense. But for most kitchens, bathrooms, additions, and decks? Design-build is the smarter move.
