Morning coffee overlooking your yard. Weekend barbecues that run late into the evening. The kind of outdoor space where your family gravitates naturally, not because you spent a fortune, but because it’s built right.
You get years of use from materials we choose specifically for Suffolk County’s coastal climate. No more worrying about warped boards or loose railings that make your deck feel unsafe.
When neighbors ask who did the work, you’ll have an answer you’re proud to give. More importantly, when it’s time to sell, buyers see a well-built deck as additional living space, not just an outdoor add-on.
Corsino Construction Corp has been serving Mastic and Suffolk County homeowners since 2000. We’re the deck builder that handles everything from permits to final cleanup, using licensed in-house professionals instead of subcontractors.
You won’t find us cutting corners on structural support or using materials that look good for six months then start falling apart. We’ve seen too many deck disasters from contractors who didn’t understand Long Island’s weather patterns or local building requirements.
Most of our work comes from referrals because people trust us to handle their projects professionally. We show up when we say we will, use the materials we promised, and finish when we committed to finish.
First, we come out to look at your space and talk through what you want. Not a sales pitch – just an honest conversation about what’s possible with your yard, your budget, and local building requirements.
Once you’re ready to move forward, we handle all permit paperwork and know exactly what Suffolk County requires for approval. This includes submitting proper plans, scheduling inspections, and making sure everything meets current building codes.
Construction starts with proper foundation work – the part you don’t see but determines how your deck performs for the next 20 years. From there, we build systematically: framing, decking, railings, and any integrated features like built-in seating or pergola attachments. You’ll see progress every day, and we clean up as we work.

We work with composite decking, pressure-treated lumber, and cedar depending on your preferences and budget. All materials are chosen for Long Island weather conditions and local building requirements.
Composite decking performs best in our climate because it resists moisture, salt air, and temperature swings without warping or splitting. It costs more upfront but saves money over time with minimal maintenance. Pressure-treated lumber costs less initially but requires annual staining and more frequent repairs.
For Mastic properties dealing with coastal weather, we use materials and fasteners designed for these conditions. Your deck includes proper footings, code-compliant railings, and appropriate spacing for our climate. Every project includes cleanup and a final walkthrough to make sure everything meets your expectations.
Yes, most deck projects in Mastic require building permits, especially if the deck is attached to your house or over 30 inches high. Suffolk County requires permits for structural work, and inspections ensure your deck meets safety codes.
We handle the entire permit process as part of our service, including submitting plans and scheduling inspections. This ensures your deck meets all local building codes and safety requirements. Skipping permits might save money upfront, but it creates serious problems when you try to sell your home or if there’s ever an insurance claim.
The permit process typically takes 2-3 weeks and costs between $150-400 depending on project scope, but we include these fees in your project estimate so there are no surprises.
Composite decking performs best in Suffolk County’s coastal climate because it resists moisture, salt air, and temperature fluctuations without warping or rotting. It handles our freeze-thaw cycles without splitting and doesn’t need regular staining like wood.
Pressure-treated lumber remains a good option if you prefer the natural wood look and don’t mind regular upkeep. It costs less initially but requires annual inspection and typically needs staining or sealing every 2-3 years to maintain weather protection.
Cedar looks beautiful but needs more frequent maintenance than pressure-treated options, especially in coastal conditions. We’ll explain the pros and cons of each material based on your specific situation and help you choose what makes sense long-term for your budget and maintenance preferences.
Deck costs in Mastic typically range from $25-60 per square foot depending on materials, design complexity, and site conditions. A basic 12×16 pressure-treated deck starts around $4,800, while composite decking with custom railings and multiple levels can reach $15,000 or more.
Most projects range from $8,000-25,000 for complete installations. The wide range reflects choices you’ll make regarding materials, size, and features like built-in seating, pergolas, or fire pit areas.
We provide detailed written estimates after seeing your space and understanding your goals. No hidden fees or surprise costs – you’ll know exactly what everything costs before we start. The most accurate approach involves an on-site consultation where we can discuss your specific needs and get pricing for different material options.
Most custom deck installations take 3-5 working days depending on size and complexity. The permit approval process typically adds 2-3 weeks before construction begins, but we handle all that paperwork for you.
Weather can affect timing, especially during foundation work or Long Island winters. We provide realistic timelines during your consultation and keep you updated if conditions cause any delays. Simple deck replacements often finish faster, while elaborate designs with pergolas or fire pits may take additional time.
We don’t start other projects until yours is finished, so you won’t deal with crews disappearing to work elsewhere. Multi-level decks or projects with integrated features may take an additional 1-2 days, but we’ll give you realistic expectations upfront based on your specific design.
Yes, we provide a comprehensive warranty on all workmanship and stand behind every deck we build. Our construction warranty covers structural issues and installation problems, while material warranties vary by manufacturer – composite decking typically includes 20-25 year warranties against fading and staining.
We use quality materials from reputable manufacturers and install everything according to their specifications to ensure warranty coverage remains valid. If structural issues arise from our construction, we fix them at no charge because most problems with new decks come from poor installation rather than material defects.
We’re a local company that depends on reputation in Mastic, so we make sure every project reflects our standards. If something goes wrong with our work, we come back and fix it at no charge because our reputation depends on satisfied customers who refer their neighbors.
Absolutely. Many customers enhance their decks with pergolas for shade, built-in seating for convenience, or fire pit areas for year-round use. These features work best when planned during initial design rather than added later.
Beyond basic deck construction, we build custom pergolas, install fire pit areas, and create multi-level designs that work with sloped yards. Pergolas require additional structural support, while fire pits need proper clearances and sometimes gas line connections.
Built-in planters, lighting systems, and storage benches are other popular additions we can integrate. The key is designing these features into the overall layout so everything looks intentional and functions well together rather than appearing as afterthoughts. We’ll walk through options that make sense for how you actually use your outdoor space.
