What we build

Four jobs, done properly.

All services
01

New composite decks

Single and multi-level decks in Trex, TimberTech, and Fiberon, framed on ground-contact lumber with joist tape and flashed ledgers, so the deck outlasts the boards' warranty.

02

Resurfacing & re-decking

Keep a sound frame, lose the gray splintered boards. New composite boards and hidden fasteners on your existing joists, usually in two to three days.

Railings & stairs

Black aluminum, cable, and composite railing systems, code-height guards, closed-riser stairs with lit treads, and replacement of wobbly wood rails.

Covered decks & porches

Gabled or shed roofs tied into your existing roofline, tongue-and-groove ceilings, fans, and screens, for shade in July and a dry deck in a March downpour.

Same frame, new deck

A typical resurfacing: three days, a third of the cost.

When the treated-pine frame under an old deck is still dry and straight, you keep it. We strip the gray boards, tape every joist, add the blocking composite needs, and lay new boards with hidden clips, then swap the loose wood rail for black aluminum. Typically about a third of the price of a full rebuild.

Built for East Tennessee

The weather here eats wood decks. We build for it.

Knoxville sits in a humid valley with heavy red clay under it. A deck here has to shrug off standing water, shifting soil, termites, and carpenter bees for decades. Every frame we build meets the Knox County deck standard and then some.

50 in.
Yearly rainfall. Every ledger gets metal flashing, every joist gets butyl tape, and low decks get 3.5 inches of ventilation clearance so the frame stays dry.
~50
Freeze-thaw cycles a winter. Footings are poured below the 12-inch Knox County frost line, and in clay we go to 18 inches with a wider bell so posts never heave.
37 days
Over 90°F a year. Boards are gapped 3/16 inch for expansion, and we help you pick colors and lines that stay comfortable underfoot in August.

Ground-contact framing. Posts, beams, and joists are ground-contact rated lumber on hot-dip galvanized hardware, which is what termite-rated Knox County soil calls for.
16″
Joist spacing, 12″ on diagonals. Composite needs a tighter frame than wood to stay stiff. We build to the manufacturer’s spec so the warranty holds.

Inspections passed for you. Footing, framing, and final. We schedule them, meet the inspector, and hand you the closed permit with your warranty paperwork.

Questions

What Knoxville homeowners ask first.

Anything else, call (865) 500-5933 and a real person will answer.

How much does a composite deck cost in Knoxville?

Most composite decks in Knox County run $30 to $60 per square foot installed, depending on the board line, railing, and stairs. A common 16 by 20 foot deck with aluminum railing typically lands between $13,500 and $19,000. Resurfacing an existing sound frame with new composite boards costs less. We quote a firm price after a free on-site visit.

Do I need a permit to build a deck in Knoxville or Knox County?

Almost always, yes. Both the City of Knoxville and Knox County build to the 2018 International Residential Code, and any deck attached to the house needs a building permit with footing, framing, and final inspections. Only a freestanding deck under 200 square feet and no more than 30 inches above grade is exempt. We prepare the drawings, pull the permit, and meet the inspector.

Composite or pressure-treated wood: which is better in East Tennessee?

Composite. Knoxville gets about 50 inches of rain a year, summer humidity in the 70s, and roughly 50 freeze-thaw cycles each winter, which is why treated pine here grays, checks, and needs restaining every two or three years. Capped composite boards from Trex, TimberTech, and Fiberon do not rot, splinter, or feed carpenter bees, and carry 25 to 50 year fade and stain warranties.

How long does it take to build a composite deck?

From first visit to finished deck, plan on 6 to 10 weeks. Design and the permit usually take 2 to 3 weeks, and the build itself is 1 to 2 weeks on site: footings and inspection, framing and inspection, decking, then railing, stairs, and the final inspection.

Can you put composite boards on my existing deck frame?

Often, yes. If the posts, beams, and joists are dry, straight, and free of rot, we strip the old boards, add joist tape and any blocking the composite needs, and lay new boards with hidden fasteners. If the frame has failed we will tell you honestly and quote a full rebuild instead.

Does composite decking get hot in the summer?

Darker composite boards do run warmer than wood in direct sun, so on a west-facing Knoxville deck we steer you toward lighter colors, heat-mitigating lines like TimberTech Advanced PVC, or a covered section. Every color option is shown on real sample boards at your estimate.
