You’re tired of looking at that old, weathered space thinking about what could be. You want an outdoor area that works for your family without constant upkeep or weather damage two years down the road.
When your custom deck is designed for Mastic Beach’s specific coastal conditions and built with materials that handle salt air and moisture, your outdoor living becomes something you actually use and enjoy year-round. No more avoiding the backyard because it’s just not functional.
Your deck becomes the place for morning coffee, weekend barbecues, and evening conversations. It’s where your family naturally gathers and where you can finally entertain without worrying about the space.
Corsino Construction Corp has been building decks and outdoor living spaces throughout Mastic Beach and Suffolk County since 2000. We understand what Long Island’s coastal weather does to outdoor structures, and we build accordingly.
You’re not getting cookie-cutter solutions here. Every deck we build is designed for your specific property, how you actually use your outdoor space, and the weather conditions your deck will face for the next twenty years.
We handle permits, follow codes, and show up when we say we will. Our licensed in-house professionals mean direct accountability throughout your project—no subcontractors, no excuses, just consistent quality craftsmanship that stands the test of time.
We start with a site visit to see your space and understand what you’re looking for. No pressure, just honest conversation about what works for your property and budget.
Every deck project includes proper foundation work, quality lumber selection, and professional installation that meets local building codes. We’re not cutting corners on the structural work you can’t see.
Most custom deck installations take 3-5 working days depending on size and complexity. We handle all permit applications and arrange inspections during construction to ensure everything meets code. You can add pergolas for shade, built-in seating, or fire pit areas if you want to create more of an outdoor living room—we’ll walk through options that make sense for how you actually use your outdoor space.

Mastic Beach properties deal with salt air and coastal weather that destroys standard construction. We use materials and fasteners specifically designed for these conditions, so your deck investment lasts.
Pressure-treated lumber works well here if properly maintained, but composite decking handles salt air and moisture better long-term. Composite costs more upfront but requires less maintenance and won’t warp or splinter. For structural framing, we always use pressure-treated lumber with galvanized or stainless steel fasteners.
Cedar looks great but needs regular sealing in coastal conditions. We’ll explain the pros and cons of each option based on your budget and maintenance preferences. Most of our deck projects range from $8,000-25,000 depending on scope, and we provide detailed written estimates that break down all costs so you know exactly what you’re paying for.
Composite decking performs exceptionally well in Mastic Beach’s salt air environment because it doesn’t rot, warp, or require annual staining like wood. However, pressure-treated lumber and cedar are still excellent choices if you prefer natural wood and don’t mind periodic maintenance.
For structural framing, we always use pressure-treated lumber with galvanized or stainless steel fasteners. Cedar looks beautiful but needs regular sealing in coastal conditions. We’ll recommend materials based on your maintenance preferences, budget, and aesthetic goals. The key is proper installation and using materials rated for coastal conditions, regardless of which option you choose.
Most decks over 30 inches high or attached to your house require building permits in Mastic Beach. We handle the permit application process and know what the local building department requires.
The permit cost is typically $100-300 depending on deck size. We also arrange inspections during construction to ensure everything meets code. Trying to skip permits can create problems when you sell your house later.
Working with contractors who understand local requirements means your project moves smoothly through the approval process without delays or compliance issues.
Most custom deck installations take 3-5 working days depending on size and complexity. Weather can affect the timeline, especially during Long Island winters, so we schedule projects realistically and keep you updated if conditions cause delays.
Larger decks with pergolas or fire pits may take an additional 1-2 days. Complex designs with multiple levels, built-in features, or challenging access may take longer, but we’ll discuss timing during your consultation so there are no surprises.
We focus on one project at a time rather than bouncing between several jobs, which means you see steady progress daily unless weather conditions prevent work.
All our deck installations include a one-year warranty on workmanship. This covers any issues with installation, structural problems, or defects in our work.
Material warranties vary by manufacturer—composite decking typically has 20-year warranties while pressure-treated lumber has shorter coverage. We’ll explain what’s covered under each warranty and provide all documentation.
If something goes wrong with our installation work, we come back and fix it at no charge. Our reputation depends on standing behind our work, and most of our business comes from satisfied customer referrals.
Yes, we design decks with pergolas, fire pits, and built-in seating as integrated features. Pergolas provide shade and define spaces for dining or lounging. Fire pits need proper clearances and ventilation, especially on covered decks.
We handle any additional permits required for fire features. The key is planning these elements during the initial design phase so the deck structure can support them properly. Adding features later often costs more and may require deck modifications.
We’ll walk through options that make sense for how you actually use your outdoor space, creating more of an outdoor living room that works for your family’s lifestyle.
Basic pressure-treated decks start around $25-35 per square foot installed. Composite decking runs $35-50 per square foot. Adding pergolas, built-in seating, or fire pits increases the total project cost.
While composite costs more upfront, it requires less maintenance and won’t warp or splinter in coastal conditions. Most of our deck projects range from $8,000-25,000 depending on scope and features.
We provide detailed written estimates that break down all costs so you know exactly what you’re paying for. No hidden fees or surprise charges—just transparent pricing based on the materials and work your project actually requires.
