What moves the price
- Height off the ground. Elevated decks need larger footings, posts and often stairs.
- Decking material — treated pine, cedar or composite.
- Railing choice, which can be 15% to 25% of a deck's cost.
- Footings in rock, common across Middle Tennessee.
What to check before you hire
- Ask for the Tennessee contractor or trade license number and confirm it is current and covers the size of your job.
- Ask for a certificate of general liability insurance, and workers' compensation if there will be a crew on your property.
- Get a written scope that lists materials by name, not just "customer's choice".
- Never pay in full up front. A deposit plus payments tied to completed stages is normal; paying ahead of work in place is not.
- Get the warranty in writing — both the manufacturer's warranty on materials and the company's own labor warranty.
- Ask who will actually be on site: the owner, employees, or subcontractors.
How to get a fair price
Get three quotes on the same written scope. If you hand each company a different description of the job, you cannot compare the numbers. Ask each one to price the same materials and the same square footage, and to list anything they are assuming.
Be careful with the cheapest and the most expensive bid. The low one is often missing something — permits, disposal, prep, or insurance. The high one may include work the others left out, which is worth asking about rather than dismissing.
Finally, ask when they can start and how long it will take. In Middle Tennessee, good companies are booked weeks out. A crew that can start tomorrow in peak season is worth a second question.
Common questions
Do decks need permits in Tennessee?
Almost always, along with an inspection of footings and framing. Rules vary by city and county.
How long does a composite deck last?
Twenty-five years or more for the surface, though the frame underneath still needs to be sound and inspected.
Deck or patio?
Patios cost less and need no maintenance, but only work on ground that is close to level with your door. Decks solve grade changes.
When should a deck be replaced instead of repaired?
When posts, beams or ledger flashing are compromised. Surface boards alone are a repair; structure is a rebuild.
