FAQ
Everything Thornton homeowners want to know before calling a deck contractor — answered honestly.
Deck costs in Thornton typically range from $8,000 to $35,000 depending on size, material (wood vs. composite), and complexity. A standard 300 sq ft composite deck averages $12,000–$18,000. We provide a free, fixed-price written estimate before any work begins — so you know the exact number upfront.
A standard deck installation in Thornton takes 5–10 days depending on size and complexity. Multi level decks or combined patio + pergola projects may take 2–3 weeks. We include a firm project timeline in your written quote before we start.
As a licensed deck contractor, we work with composite, pressure-treated wood, cedar, and hardwoods. We recommend composite for Colorado — it resists UV, hail, and freeze-thaw far better than natural wood.
Absolutely — custom and multi level decks are one of our most requested builds. We design and construct curved, split-level, rooftop, and wrap-around decks across Thornton and the Denver metro.
We serve cities across Thornton, Denver, Aurora, Arvada, Westminster, Broomfield, Northglenn, Brighton, Commerce City, Welby, Superior, Louisville, Lafayette, and Wheat Ridge. Same licensed crew, every city.
Deck repair addresses specific structural issues — rotted boards, loose railings, damaged joists. Deck restoration is a more complete process: cleaning, sanding, re-sealing, and replacing worn components to bring the deck back to like-new condition without a full rebuild.
Deck repair cost in Thornton ranges from $500 for minor board replacement to $5,000+ for structural repairs involving joists or posts. We include a free estimate with every repair quote so you know exactly what needs fixing before committing to anything.
High-quality composite decking like Trex Transcend typically lasts 25–30 years in Colorado’s climate with minimal maintenance. It outperforms natural wood — which typically lasts 10–15 years — against Colorado’s intense UV, hail, and hard freeze-thaw cycles.
