The material question comes up on almost every deck estimate we walk. Homeowners in Severna Park, Bethesda, and Fairfax have usually seen a neighbor's deck they like, read a little online, and landed somewhere between "I think I want composite" and "my dad always said real wood." We sit down, walk the yard, and the first real conversation is about which material fits the house, the budget, and the weather we actually get out here.
Mid-Atlantic weather is the piece most comparison articles skip. Maryland and Northern Virginia hand a deck four distinct stress tests every year: summer humidity that stays in the 70s and 80s for weeks, July sun that cooks south-facing boards, fall leaf cover that traps moisture, and winter freeze-thaw cycles that pry at every fastener and board seam. Here is how pressure-treated, cedar, composite, and exotic hardwood actually hold up, and what each one costs to build and to live with.
Pressure-Treated Wood: The Budget Floor
Pressure-treated pine is the material under roughly half the existing decks in Anne Arundel and Howard counties. It is cheap, widely available, and easy to work with. A simple 12×16 pressure-treated deck, uncovered, runs roughly $8,000 to $14,000 installed in our market.
The catch is maintenance and lifespan. Pressure-treated boards want a clean, a sand, and a fresh stain or seal every two years. Skip a cycle in our humidity and you get the classic mid-Atlantic deck story: cupped boards, gray patches, a splinter or two near the stairs, fasteners working loose. Freeze-thaw accelerates all of it. Realistic lifespan with regular upkeep is 12 to 15 years. Without upkeep, you are looking at replacing boards sooner than that.
It is still the right choice when the budget does not stretch further and the alternative is no deck, or when the deck is a small utility platform — a landing off a back door, a grill pad — not the centerpiece of the yard.
Cedar: The Natural-Wood Middle Ground
Western red cedar is the quiet favorite for homeowners who want a real wood deck without the pressure-treated maintenance tax. Cedar contains natural oils that resist rot and insects, it takes stain beautifully, and it ages into a silver-gray patina that looks at home next to craftsman and colonial exteriors across Ellicott City and Annapolis.
Pricing lands between pressure-treated and composite. For the same 12×16 footprint, cedar typically runs $12,000 to $18,000 installed. Lifespan is 15 to 20 years with modest upkeep — a wash and a light refresh of semi-transparent stain every year or two.
Cedar's weakness in our climate is poor drainage. A cedar deck over a damp, shaded yard will not last as long as the same deck over a sunny, well-drained site. We design for this with proper joist spacing, hidden fasteners that do not trap water, and enough clearance underneath for air to move.
If you are choosing between cedar and composite and you genuinely like the look and smell of real wood, cedar is worth the small trade-off in maintenance. If you want to never touch the deck again, skip to the next section.
Composite: Where Most of Our Clients Land
Trex, TimberTech, and Fiberon dominate the composite conversation in 2026, and for a practical reason: they have largely solved the problems that gave early composite a bad reputation. The current generation of capped composites resist fading, resist staining, and carry 25-year or 50-year warranties depending on the line.
For Mid-Atlantic conditions, composite's advantages stack up. Humidity does not cup it. Freeze-thaw does not split it. Leaf tannins wash off. You give up the warmth of real grain, and dark colors get hot in direct July sun on a south-facing deck — worth thinking about if you walk barefoot out there. Lighter tones handle the sun better.
Installed pricing in Maryland and Northern Virginia:
- Entry-level composite (Trex Enhance, TimberTech Reserve): roughly $20,000 to $28,000 for a 14×20 with railings, steps, and basic lighting.
- Mid-tier capped composite (Trex Transcend, TimberTech Legacy, Fiberon Concordia): $28,000 to $38,000 at the same size.
- Premium composite with PVC cap: $35,000 to $50,000, approaching hardwood territory.
Multi-level composite builds with built-in bench seating, a pergola, and proper landscape integration typically run $40,000 to $70,000. That is the tier most of our Bethesda and Reston clients build at when they want the backyard to do real work as entertaining space.
The math most homeowners miss: skip 10 years of staining and sealing on pressure-treated or cedar and composite pays for most of its premium in saved weekends and saved material costs. If you are already choosing between the three, composite often wins on total cost of ownership even when it loses on sticker price.
Exotic Hardwood: Ipe and Mahogany
Ipe (pronounced ee-pay) and Brazilian mahogany are the top tier of decking material. Density so high ipe will sink in water. Lifespan of 40 to 75 years with basic care. On the right house — a premium contemporary in Great Falls, a waterfront property on the Severn — nothing else looks quite right.
Installed ipe for a 14×20 deck runs roughly $45,000 to $65,000, or 30 to 50 percent above premium composite. Mahogany lands slightly below. You are paying for material, specialty hidden fasteners designed for hardwood, and more labor — every hole gets pre-drilled through the density.
For Mid-Atlantic weather, hardwood is exceptional. Ipe shrugs off humidity and freeze-thaw. It grays without oiling, though most clients who spend this much want the rich brown tone and commit to an annual oil coat. If you are building to last decades and cost is not the primary constraint, this is the material. For most MD and NoVA homes, composite or cedar hits the sweet spot and ipe is a stretch the budget does not need to make.
Putting It Together
- Pressure-treated: $8,000 to $14,000 · 12 to 15 years · stain every 2 years.
- Cedar: $12,000 to $18,000 · 15 to 20 years · light refresh yearly.
- Composite: $20,000 to $50,000 by tier · 25+ year warranty · wash occasionally.
- Ipe / mahogany: $45,000 to $65,000+ · 40 to 75 years · oil annually for color.
Material drives roughly 40 to 50 percent of total deck cost. The rest is framing, railings, stairs, lighting, permits, and built-ins. A young family in Crofton building a first real outdoor room often lands on mid-tier composite. A couple in Reston upgrading a tired cedar deck sometimes stays with cedar because they love how the old one looked before it went gray. An empty-nester in Annapolis on the water may decide ipe is the right once-and-done answer.

Ready to Talk Materials?
The best first step is a free in-home consultation. We come out, walk the yard, look at the exposure, the drainage, the house's exterior palette, and what you want the space to do. Then we show you samples of the materials that actually make sense for your site and leave you with a 3D design preview. No pressure, no upsell, just a real conversation about which deck fits your house.
Call us at (410) 610-5839 for Maryland or (571) 835-8875 for Northern Virginia. Or take a look at our outdoor decks service page for project examples across Severna Park, Ellicott City, Bethesda, and Fairfax. If the deck conversation has been an every-spring ritual for a while, this is a good year to stop talking about it and build.
