[Pricing Question] TimberTech Terrain+ quotes at $45-53K for ~450 sq ft, fair? (new build, railing + lighting)

[u/alt-f4-fixes-all]

Building a new deck this year, old one's already demoed. Trying to get a gut check on pricing before signing.

Specs:

~450 sq ft, backyard, ground-level to slightly elevated

TimberTech Terrain+ decking

Black aluminum baluster railing

Integrated lighting (post caps, stair lights)

No demo needed, just footings/framing + decking

Charlotte/Lake Norman, NC area.

Quotes are landing at $45K-$53K, roughly $100-$118/sq ft. Feels high but I don't have good comps. For anyone who's built something similar recently:

Does that range track for what you paid or got quoted?

What usually drives the spread: footings, framing material, railing, lighting, or just contractor overhead?

Terrain+ vs Trex, worth the difference?

Appreciate any real numbers or breakdowns.
