Composite & Custom Deck
Builder
in Delaware

Deck costs in Delaware vary based on size, materials, and complexity. A basic 12x12 pressure-treated wood deck starts around $4,000-6,000 installed. A comparable composite deck (Trex or TimberTech) ranges from $8,000-15,000. Multi-level decks, covered structures, and premium features increase costs.

For Delaware's climate — with hot, humid summers and freezing winters — we recommend capped composite decking from brands like Trex Transcend or TimberTech. These materials resist moisture, won't crack from freeze-thaw cycles, and require virtually no maintenance. For budget-conscious homeowners, pressure-treated lumber is a solid choice with proper annual maintenance.

Most residential deck projects take 2-4 weeks from start to finish. A simple ground-level deck may take 1-2 weeks, while a complex multi-level deck with stairs, pergola, or built-in features can take 3-5 weeks. This timeline includes permit approval, which typically takes 2-4 weeks in New Castle County. Weather delays can extend the schedule.

In most cases, yes. New Castle County requires a building permit for decks that are attached to the house, more than 30 inches above grade, or exceed 200 square feet. The permit process includes plan review, approval, and inspections at key construction stages. ProDecks handles all permitting as part of our service — you don't need to worry about paperwork.

Wood decking (pressure-treated pine, cedar) costs less upfront but requires annual staining/sealing and has a 10-20 year lifespan. Composite decking (Trex, TimberTech) costs more initially but is virtually maintenance-free and lasts 25-50 years. Composite won't rot, splinter, or warp. Over a 20-year period, composite often costs less when you factor in maintenance savings.

For composite decks: sweep regularly, rinse with a hose monthly, and clean any mold spots with a deck cleaner. For wood decks: sweep weekly, power wash annually (low pressure), and apply stain/sealer every 1-2 years. Inspect all decks seasonally for loose boards, wobbly railings, and structural issues. See our complete Deck Maintenance Guide for detailed seasonal tips.

Absolutely! Uneven or sloped terrain is actually one of ProDecks' specialties. We design multi-level decks, elevated platforms, and stepped structures that work with your terrain rather than against it. Sloped yards in areas like Hockessin and Pike Creek often result in the most dramatic and beautiful deck designs, with built-in stairs and tiered entertaining spaces.
