Custom Deck Builder in Johnson City & The Tri-Cities
I&G Construction Services designs and builds custom residential decks for homeowners across the Tri-Cities area — Johnson City, Kingsport, Bristol, Jonesborough, and surrounding communities throughout Washington County, Sullivan County, and Carter County.
A deck isn’t just lumber and screws. It’s an extension of your home that has to stand up to East Tennessee’s full range of weather — summer heat and humidity that promotes mold and wood rot, winters that bring freezing temperatures and ice, spring storms that test every fastener and footing. We build decks that are designed for this climate, built to local codes, and constructed to last.
Whether you’re looking for a simple pressure-treated wood deck off your back door, a multi-level composite build overlooking your property, or repairs to an aging deck that needs structural attention — we handle the full project from initial design through final walkthrough.
We serve homeowners across the entire Tri-Cities metropolitan area, including Johnson City, Kingsport, Bristol, Jonesborough, Elizabethton, Gray, Piney Flats, and surrounding communities in Washington County, Sullivan County, and Carter County.
Deck Materials We Work With In East Tennessee
Choosing the right decking material is the single biggest decision in your project. It affects how your deck looks, how long it lasts, how much maintenance it requires, and what it costs. We work with three primary material categories and help you choose based on your budget, your maintenance tolerance, and how you plan to use the space.
Pressure-Treated Wood Decks
Pressure-treated southern yellow pine is the most popular and affordable decking material in the Tri-Cities. It’s treated to resist rot, decay, and insects — all real concerns in East Tennessee’s humidity. The tradeoff is maintenance: you’ll need to clean, stain, and seal every 1 to 2 years to prevent graying, splintering, and rot.
We build pressure-treated decks with proper board spacing for drainage, flashing at all ledger connections, and corrosion-resistant fasteners. These details are the difference between a deck that lasts 10 years and one that lasts 25.
Best for: Homeowners on a tighter budget who don’t mind annual maintenance or who prefer the look and feel of real wood.
Composite Decks — Trex, TimberTech & More
Composite decking is engineered from recycled wood fibers and plastic polymers to resist everything that destroys wood decks in East Tennessee — moisture, mold, insects, UV fading, and freeze-thaw warping.
The upfront cost is 2 to 3 times higher than wood, but composite requires almost zero maintenance. No staining, sealing, or sanding — just occasional soap and water. Over a 20 to 25 year lifespan, many homeowners find composite actually costs less when you factor in annual wood deck upkeep. We install Trex, TimberTech, and other leading brands with manufacturer warranties ranging from 25 to 50 years. We follow manufacturer specs to keep your warranty valid.
Best for: Homeowners who want low-maintenance outdoor living and are willing to invest more upfront to eliminate ongoing costs.
Cedar Decks
Western red cedar naturally resists insects and decay without chemical treatment. It has a warm, reddish-brown tone that many homeowners prefer over the greenish hue of fresh pressure-treated pine. Cedar costs more than treated wood but less than composite, and still requires staining and sealing every 1 to 2 years. Left untreated, it weathers to a silver-gray.
Cedar is softer than pine — more comfortable barefoot but more susceptible to dents from furniture and heavy traffic.
Best for: Homeowners who want a natural wood look with better rot resistance than pine and are comfortable with periodic maintenance.
Custom Deck Features and Add-Ons
A deck is more than just a floor surface. The details and features are what turn a basic deck into a genuine outdoor living space. We offer the following custom features on new builds and as upgrades to existing decks:
- Railings — We install wood, composite, metal baluster, horizontal cable, and glass panel railing systems. Railing style has a major impact on the overall look and feel of your deck, and we help you choose a system that complements your home’s architecture. Code-compliant railing is required on any deck surface more than 30 inches above grade.
- Stairs — From simple straight-run stairs to L-shaped, switchback, and wraparound configurations. We build stairs that integrate with your deck design and meet code requirements for tread depth, riser height, and handrail specifications.
- Pergola and shade structures — Attached pergolas and shade structures provide relief from East Tennessee’s strong summer sun. We build them to integrate structurally with your deck so they’re secure and code-compliant.
WHY I & G CONSTRUCTION SERVICES
Why Tri-Cities Homeowners Choose I & G Construction
There’s no shortage of contractors in the Tri-Cities area. Here’s why homeowners choose to work with us over the alternatives:
Locally Owned and Operated
We’re based in Johnson City and serve the Tri-Cities area exclusively. We’re not a franchise, not a national chain, and not a crew driving in from Knoxville or Charlotte. We live here. We shop at the same stores you do. When we tell you we know the soil conditions in Washington County or the building code process in Kingsport, it’s because we’ve actually dealt with them — not because we read about them online.
Fully Insured
We carry full general liability insurance on every project. Your home and property are protected while we work. We’ll provide a certificate of insurance before any work begins — you don’t even have to ask.
No Subcontractors
When you hire I&G Construction, our crew shows up. We don’t pass your project off to subcontractors you’ve never met. You’ll see the same faces on day one that you see on the final walkthrough. That consistency is how we maintain quality control across every project.
Free On-Site Estimates
We come to your property, take measurements, discuss your goals, and provide a detailed written estimate — free of charge, no obligation. Our estimates are itemized so you can see exactly what you’re paying for: materials, labor, permits, and timeline. No hidden fees, no vague “starting at” pricing.
Honest Communication From Start to Finish
We tell you what the project will cost, how long it will take, and what to expect — before any work starts. If something changes during the project, you’ll hear about it immediately, not on the invoice. We believe the best business relationships are built on straightforward communication, and that’s how we operate on every single job.

HOW IT WORKS
Our Deck Building Process
A straightforward process with no surprises. Here’s what to expect when you work with I&G Construction Services.
1
Free On-Site Estimate
We come to your property, take measurements, assess your lot conditions (grade, soil, access, proximity to property lines), discuss your goals, your material preferences, and your budget. We then provide a detailed written estimate that itemizes materials, labor, permits, and timeline. No vague ranges. No “we’ll figure it out as we go.” You’ll know exactly what you’re paying for before you agree to anything.
2
Design & Permitting
Once you approve the estimate, we finalize the deck design and submit for any required building permits. In Johnson City, permits are handled through the Building Inspections Department. In Kingsport, it’s the Department of Planning and Community Development. Bristol, Jonesborough, and unincorporated county areas each have their own process. We know the requirements for each jurisdiction in the Tri-Cities and handle the paperwork so you don’t have to.
3
Material Procurement and Scheduling
We order materials from local suppliers in the Tri-Cities area and coordinate delivery to your property. We confirm your start date, provide an estimated completion date, and make sure you know exactly when to expect our crew on site.
4
Construction & Final Walkthrough
Our crew handles the full build — footings, framing, decking, railings, stairs, and all finishing details. We keep the jobsite clean, communicate daily, and coordinate any required inspections with your local building department. When the build is complete, we walk the finished deck with you to make sure every detail meets your expectations. We remove all debris, clean the site, and don’t consider the job done until you’re satisfied.
COMMON QUESTIONS
Deck Building FAQ for Tri-Cities Homeowners
Answers to the questions we hear most from homeowners in Johnson City, Kingsport, Bristol, and surrounding areas.
Deck costs in the Tri-Cities area vary based on size, materials, elevation, and features. As a general guide, a standard pressure-treated wood deck typically runs $5,000 to $15,000. Composite decks range from $12,000 to $30,000 or more. Multi-level builds, extensive railings, stairs, and features like pergolas or under-deck drainage push costs higher. We provide free on-site estimates with exact pricing for your specific project — no guessing required.
In most cases, yes. Within Johnson City city limits, the Building Inspections Department requires permits for deck construction — particularly if the deck is attached to the house, elevated more than 30 inches above grade, or larger than 200 square feet. Kingsport, Bristol, and Jonesborough each have their own permit requirements through their respective building departments. For properties in unincorporated areas, county building departments handle permits. We manage the entire permit process for you regardless of your location in the Tri-Cities.
Most residential decks take 1 to 3 weeks from the start of construction to completion. Simple ground-level platform decks can be finished in under a week. Larger multi-level builds with custom railings, stairs, and features may take 3 weeks or longer. Weather can affect the timeline — East Tennessee’s spring rain season and occasional winter weather can cause delays. We provide a realistic timeline estimate before starting every project and communicate any changes immediately.
For many East Tennessee homeowners, composite is an excellent long-term investment. Our climate is hard on wood — the humidity promotes mold and mildew, the temperature swings cause expansion and contraction that warps boards, and insects are active for most of the year. Composite resists all of these issues and eliminates the need for annual staining, sealing, and sanding. While you’ll pay more upfront, you’ll spend almost nothing on maintenance over the deck’s 25 to 50 year expected lifespan.
Both pressure-treated wood and composite perform well in East Tennessee when installed correctly. The best choice depends on your priorities. If you want the lowest upfront cost and don’t mind annual maintenance, pressure-treated wood is a solid option. If you want minimal long-term maintenance and the best resistance to our humidity and temperature swings, composite is the stronger choice. We walk you through the pros, cons, and costs of each option during your free estimate.
Yes, and this is one of the most common scenarios we encounter in the Tri-Cities. Many properties across Johnson City, Kingsport, and the surrounding areas sit on sloped or hillside lots. We design raised and multi-level decks that work with the natural grade of your property, using proper footings and structural engineering to create a level, safe deck surface at your desired height.
