Connecticut's AlumaDeck Deck Builder and Contractor
Why Connecticut Homeowners Are Choosing AlumaDeck Over Wood and Composite
Rot and Moisture Damage
Wood rots from moisture intrusion at every screw hole and end cut. Composites absorb moisture and swell at the joints over time.
✓ Solution: Will not rust, crack, fade, or degrade from the elements or UV exposure. Zero moisture absorption. No rot, ever.
Freeze-Thaw Damage
Wood splits and warps when water trapped in the grain freezes and expands. Connecticut’s freeze-thaw cycles destroy standard decks.
✓ Solution: Aluminum is dimensionally stable through freeze-thaw cycles. AlumaDeck planks do not absorb water, so there is nothing to freeze and expand.
Salt-Air Corrosion
Coastal Connecticut decks face accelerated wood rot and composite color fade from salt-laden humidity from Long Island Sound and tidal rivers.
✓ Solution: Saltwater tested. AlumaDeck withstands coastal Connecticut salt-air environments without corrosion, staining, or surface degradation.
Maintenance Burden
Wood decks require annual sanding, staining, or painting to maintain appearance and structural integrity. Composites need periodic cleaning.
✓ Solution: Maintenance-free. No sanding, staining, painting, or sealing. The deck you install today looks and performs the same a decade from now.

Deck Installation FAQs for Connecticut
What is AlumaDeck, and how is it different from composite decking?
AlumaDeck is the Sunspace aluminum decking system — 100 percent aluminum planks that will not rust, crack, fade, warp, or grow mold. Key differences from composite decking:
- AlumaDeck is guaranteed to outlast any wood, membrane, or plastic-based deck product. Composite decking carries no such guarantee.
- AlumaDeck is saltwater-tested and fire safe to 1,220 degrees Fahrenheit — specifications no composite product matches.
- Composite decking is a wood-fiber and plastic blend that retains many of wood’s failure modes, including freeze-thaw damage, UV color fade, and mold growth in grooves.
Does aluminum decking get hot in direct Connecticut summer sun?
No. AlumaDeck is a thermal conductor, not a thermal mass. It does not hold heat the way wood, composite, or concrete surfaces do. South-facing decks in Hartford, New Haven, and Stamford that receive full afternoon sun in July and August are more comfortable underfoot with AlumaDeck than with any comparable wood or composite surface.
Can AlumaDeck be used on an existing wooden deck structure?
Yes. AlumaDeck installs on both aluminum and wooden structure undersides. If your existing deck frame is structurally sound, AlumaDeck planks can replace your existing decking surface without a full teardown. We assess the framing at the free consultation and confirm suitability for the installation.
What colors are available for AlumaDeck?
AlumaDeck is available in six standard powder-coated finishes: Gray, Cedar, Gray Woodgrain, Sand, Taupe, and Spruce. All six are designed to provide the visual warmth of natural wood-look decking without any of the maintenance, rot, or UV-fade issues of real wood.
Can AlumaDeck stairs be added to a new or existing deck?
Yes. The AlumaDeck Stair System installs on both aluminum and wooden structure undersides and pairs with any of the four Sunspace railing systems. Stairs can be specified at the same time as the deck installation or added to an existing AlumaDeck surface later.
Key stair dimensions:
- Maximum rise: 5 feet 2 inches before extra supporting structure
- Minimum width: 3.6 inches
- Maximum width: 12 feet with mid stringer
- Tread depth: 12 inches
- Tread rise range: 5 inches to 7-7/8 inches
Can I add a railing alongside my AlumaDeck installation?
Yes. AlumaDeck integrates directly with all four Sunspace railing systems: Aluminum Picket, Aluminum Railing with Glass, Topless Glass, and Integrated Railings and Screens. Railing is typically specified at the same time as the deck installation. Planning railing post positions before the planks go down produces a cleaner result than retrofitting posts to an existing deck surface.
Can I add a patio cover over my AlumaDeck?
Yes. A Sunspace patio cover is the natural overhead complement to an AlumaDeck installation. An insulated, acrylic, or hybrid roof system creates a fully covered outdoor living space that stays dry through Connecticut’s 46 annual inches of rainfall. Our patio cover installation service covers all three roof system options and can be specified and quoted at the same time as your deck installation.
Can AlumaDeck be installed for a commercial property?
Yes. AlumaDeck is suitable for home, cottage, and commercial use throughout Connecticut. The saltwater-tested specification and fire safety rating at 1,220 degrees Fahrenheit make it well-suited for commercial outdoor seating. Our commercial outdoor living service covers commercial AlumaDeck installations using the same factory-certified process as residential projects.
Can I combine a deck installation with a sunroom or screen room?
Yes. AlumaDeck integrates with the full Sunspace product lineup, including sunroom and screen room systems. A deck with the correct framing accepts Sunspace window, door, and enclosure systems on the perimeter, allowing a future conversion to a fully enclosed sunroom.
