Deck Construction — Custom Decks & Patios

Custom Decks Built for Your Lifestyle

A well-designed deck transforms your backyard into an extension of your living space. On Long Island, where outdoor seasons stretch from spring through late fall, a quality deck becomes the center of family gatherings, barbecues, morning coffee, and evening relaxation. At Alec's Construction, we design and build custom decks that reflect how you actually live — not cookie-cutter designs pulled from a catalog.

Every deck project starts with a thorough walkthrough of your property. We evaluate the terrain, soil conditions, existing structures, and your vision for the space. Then we create a design that maximizes your outdoor living potential while respecting your budget and local building codes.

Decking Materials

The material you choose determines the look, maintenance requirements, and lifespan of your deck. We install and recommend:

• Composite Decking (Trex, TimberTech, Fiberon) — The modern standard for low-maintenance outdoor living. Composite boards are made from a blend of wood fibers and recycled plastics, creating a surface that resists fading, staining, scratching, and mold. No sanding, staining, or sealing — ever. Available in dozens of colors and wood-grain textures. Most composite manufacturers offer 25-year to limited-lifetime warranties.
• Pressure-Treated Wood — The most affordable decking option. Pressure-treated lumber is chemically treated to resist rot, insects, and fungal decay. It accepts stain and paint well, allowing you to customize the look. Requires periodic staining or sealing every 2-3 years to maintain its condition and appearance.
• Cedar & Redwood — Naturally rot-resistant softwoods that offer warm tones and beautiful grain patterns. Cedar is lighter and easier to work with than most hardwoods, making it popular for railings and accent features. Requires annual or biannual sealing to maintain its rich color.
• Hardwood (Ipe, Mahogany) — Premium tropical hardwoods that deliver unmatched density, durability, and natural beauty. Ipe decking can last 40+ years and is incredibly resistant to scratches, insects, and weather. It is the most expensive option but also the most long-lasting.

Railings, Pergolas & Add-Ons

A great deck is about more than just the floor. We build complete outdoor living systems that include:

• Cable Railings — Sleek, modern stainless steel cable systems that provide safety without obstructing views. Perfect for elevated decks and properties with landscape or water views.
• Aluminum & Composite Railings — Durable, low-maintenance railing systems available in a variety of colors and styles to complement your decking material.
• Pergolas & Shade Structures — Custom-built pergolas provide filtered shade and architectural interest. Available in wood, composite, and aluminum with optional retractable canopies.
• Built-In Benches & Planters — Integrated seating and planter boxes maximize space and create a cohesive design without the need for separate furniture.
• Deck Lighting — Recessed stair lights, post cap lights, and under-rail LED strips extend your outdoor living hours and enhance safety.

Permits & Building Codes

In Suffolk County, most deck projects require a building permit, especially if the deck is attached to the house, elevated more than 30 inches above grade, or exceeds a certain square footage. We handle the entire permitting process — from preparing plans and site surveys to submitting applications and scheduling inspections. Every deck we build meets or exceeds current New York State Residential Code requirements for structural integrity, railing height, stair dimensions, and ledger board attachment.
