Portland, ME's Trusted Deck Building Company Since 1978
Deck Installation in Portland, ME
Wood warps, rots, and demands constant attention. AlumaDeck is engineered to outlast every wood, composite, and membrane-based deck system on the market, with zero painting, staining, or seasonal prep required.
The Problem with Wood and Composite Decking
Portland's Climate Destroys Ordinary Decks
100+
Frost days per year in Portland. That’s nearly five months when your outdoor space sits unused without a proper enclosure.
Stat Block: 3 to 5 years. That is how long most wood decks in Maine’s coastal climate last before they require sanding, staining, sealing, or partial board replacement just to maintain their appearance and structural integrity.
Portland’s freeze-thaw cycles, coastal humidity, salt air, and UV exposure accelerate the degradation of wood and composite materials. Boards crack, surfaces fade, and the annual maintenance cycle consumes weekends that should be spent on the deck, not working on it.
AlumaDeck eliminates all of that. It will not rust, crack, fade, warp, or degrade from elements or UV exposure, and it is guaranteed to outlast any wood, membrane, or plastic-based product.
Zero Lifetime Maintenance
No painting, staining, sealing, or sanding, ever. AlumaDeck requires nothing more than an occasional sweep and a rinse with soap and water.
100% Watertight
The interlocking panel design creates a fully watertight surface that drains water off the deck efficiently, eliminating pooling and the structural damage it causes.
Cool to the Touch
As a thermal conductor, aluminum dissipates heat rather than holding it. AlumaDeck stays cool to the touch even in peak summer sun, unlike composite or rubber surfaces.
Fire-Safe
AlumaDeck is fire-resistant up to 1,220°F (660°C), making it a significantly safer surface choice than wood or composite alternatives for residential and commercial applications.
Eco-Friendly
Free from harmful toxins and fully recyclable at the end of its lifespan. AlumaDeck contains no pressure-treated chemicals, no VOCs, and no materials that leach into the ground.
Guaranteed to Outlast the Alternatives
Sunspace guarantees AlumaDeck will outlast any wood, membrane, or plastic-based decking product, making it the last deck investment most homeowners will ever need to make.
The AlumaDeck System
Portland's Premier Aluminum Decking Solution
AlumaDeck is Sunspace’s proprietary aluminum decking system, designed as the most versatile and durable deck surface available for residential, commercial, and cottage applications. It is watertight, slip-resistant, and weather-resistant without sacrificing structural strength or surface quality.
Every AlumaDeck installation is custom-built to your specific dimensions and integrates directly with Sunspace railing systems, sunroom foundations, and patio cover structures for a complete, cohesive outdoor living setup.
System Features and Benefits
Durability Performance:
- Will not rust, crack, or fade: Engineered aluminum construction holds its finish and structural integrity through Maine’s coastal conditions and freeze-thaw cycles
- UV-stable surface: No fading, discoloration, or surface degradation from prolonged sun exposure
- Scratch-resistant finish: Maintains its appearance under heavy foot traffic, furniture movement, and outdoor use
- Guaranteed to outlast wood, membrane, and plastic alternatives: A manufacturer-backed performance guarantee, not a marketing claim
Safety and Comfort:
- Slip-resistant surface: Textured aluminum surface maintains grip when wet, critical for Maine’s rain and coastal conditions
- Cool to the touch: Aluminum conducts heat away from the surface rather than storing it; never becomes uncomfortably hot underfoot
- Fire-resistant to 1,220°F (660°C): A level of fire safety no wood or composite surface can approach
Environmental and Practical Advantages:
- No harmful toxins: Free from the preservative chemicals used in pressure-treated wood; safe for children, pets, and surrounding soil
- Fully recyclable: At the end of its lifespan, the aluminum material is completely recyclable with no environmental waste
- Watertight panel design: Interlocking structure directs water off the deck surface efficiently and protects the structure below
Integration and Versatility:
- Compatible with Sunspace railing systems: Pairs directly with Topless Glass, Aluminum Picket, Aluminum with Glass, and Integrated Screen railing systems for a unified finish
- Integrates with sunroom and patio cover systems: AlumaDeck serves as the structural deck base for sunroom installations and covered outdoor spaces
- Suitable for residential, commercial, and cottage use: One system that performs across all application types
- Available in freestanding or attached configurations: Flexible installation options for new builds and existing structure upgrades
- Stair applications available: Slip-resistant, watertight aluminum decking steps for multi-level configurations

Common Questions
Deck Installation FAQs
Everything Portland homeowners ask before scheduling their first consultation.
AlumaDeck is Sunspace's proprietary aluminum decking system, built from corrosion-resistant structural aluminum with a watertight interlocking panel design. Unlike composite decking, AlumaDeck will not fade, warp, crack, or degrade under UV exposure, and it requires no maintenance whatsoever throughout its lifespan. It is also fire-resistant to 1,220°F, which no composite product can match.
No. Aluminum is a thermal conductor, which means it dissipates heat rather than storing it. AlumaDeck stays noticeably cooler to the touch than composite, rubber, or dark wood surfaces under the same direct sun exposure, making it more comfortable for bare feet on warm Maine afternoons.
In many cases, yes. AlumaDeck can be installed over most wood or concrete surfaces as a replacement decking layer, which can reduce the cost and complexity of a full rebuild. Our consultants assess your existing structure during the free on-site consultation to determine whether a surface replacement or a full new build is the right approach.
Yes, and this is one of its key advantages. AlumaDeck integrates directly with all four Sunspace railing systems, including Topless Glass, Aluminum Picket, Aluminum with Glass, and Integrated Screen railings. Choosing AlumaDeck as your decking surface makes railing installation cleaner, faster, and more visually unified.
Absolutely. AlumaDeck frequently serves as the structural deck base beneath a new sunroom installation, and it pairs naturally with a custom patio cover over an adjacent uncovered outdoor area. Scoping the deck, sunroom, and cover together as one project typically results in a more cohesive finished result and a more efficient installation timeline.
Yes. AlumaDeck is designed for residential, cottage, and commercial use alike. Its slip-resistant surface, fire resistance, and zero-maintenance construction make it particularly well-suited for commercial outdoor spaces that cannot accommodate frequent maintenance cycles.
Yes. We install AlumaDeck and complete outdoor living systems throughout Southern Maine and surrounding communities. Visit our service areas page to confirm your location, or call us directly.
