 Design Build Blog:  How a Fiberon Deck Looks After 3 Years

One of the most common questions we hear at Design Builders is: "How will my deck hold up over time?" It's a smart question—you're investing $20,000 to $80,000 in your outdoor space, and you want to know it'll still look great years down the road.

Today, we're revisiting several decks we built 3-5 years ago in Montgomery County and Fairfax County to show you exactly how different materials age in our Maryland and Virginia climate. No marketing hype, no staged photos—just real-world results from actual client projects.

Composite Decking After 3 Years: The Clear Winner for Low Maintenance

We built a 480 square foot Trex deck in Bethesda in spring 2022. The homeowners chose the Havana Gold color in Trex's Transcend line. Here's what it looks like after three Maryland summers:

The Good:

  • Color virtually unchanged (maybe 5% lighter, barely noticeable)
  • No splintering, cracking, or warping
  • Stains from kids' popsicles and dropped food cleaned right off
  • No maintenance beyond occasional hosing down

The Not-So-Good:

  • Some light scratching near the grill from dragged furniture
  • Slight fading on south-facing boards (to be expected)
  • One board developed minor cupping (replaced under warranty)

Maintenance Required: Zero. Literally just occasional power washing.

Client's Assessment: "We'd build it the same way again in a heartbeat. The lack of maintenance alone is worth the investment."

Pressure-Treated Wood After 3 Years: Depends Heavily on Maintenance

In 2021, we built a 600 sq ft pressure-treated pine deck in Gaithersburg. The homeowner chose natural wood specifically because he enjoys the maintenance ritual and wanted the authentic wood look.

With Annual Maintenance (This Client):

  • Cleaned and re-stained every spring
  • Tightened any loose boards
  • Replaced a few cupped boards (normal with PT wood)
  • Overall appearance: Excellent—looks almost new

Without Proper Maintenance (We've Seen Others):

  • Gray weathering within 18 months
  • Splintering starting by year 2
  • Some boards starting to cup or crack
  • Fasteners showing rust stains

Maintenance Required:

  • Annual cleaning and staining: 8-12 hours labor + $200-400 in materials
  • Board inspection and replacement as needed
  • Fastener check and tightening

Client's Assessment: "I love working on it each spring. It's therapeutic for me. But I totally understand why people choose composite."

TimberTech (Azek) After 3 Years: Premium Performance

One of our Potomac clients chose TimberTech's Azek Vintage collection in Mahogany for their 520 sq ft deck in early 2022. This is the premium end of composite decking.

The Results:

  • Color retention: Exceptional (truly looks brand new)
  • Heat retention: Moderate (stays cooler than earlier composite materials)
  • Scratch resistance: Very good (some light scratches but barely visible)
  • Stain resistance: Excellent (wine spills, grill grease—all cleaned off)

Maintenance Required: Quarterly washing with mild soap and water

Client's Assessment: "Worth the extra investment. We're outside constantly and it still looks perfect."

Ipe (Brazilian Hardwood) After 3 Years: Beautiful But High Maintenance

We built an Ipe deck in Chevy Chase in 2020. At over $16 per square foot just for materials, this 400 sq ft deck represented a significant investment.

With Proper Oiling (Twice Yearly):

  • Gorgeous rich brown color maintained
  • No structural issues whatsoever
  • Extremely dense and durable
  • Premium look that composite can't match

Without Oiling (We've Seen Examples):

  • Beautiful silver-gray patina develops
  • Some clients love this weathered look
  • Others disappointed by color change
  • Still structurally perfect

Maintenance Required:

  • Oil every 6 months: 6-8 hours labor + $150-200 in oil
  • OR accept natural graying

Client's Assessment: "It's absolutely beautiful and we love it, but the maintenance is real. If we were building again, we'd seriously consider high-end composite."

What Causes Aging Issues in All Deck Types?

Based on our experience, here are the factors that most affect how your deck ages:

1. Sun Exposure

Impact: South and west-facing decks show the most fading Solution:

  • Choose fade-resistant materials
  • Use lighter colors (show fading less)
  • Consider pergola or shade structure

2. Moisture and Drainage

Impact: Standing water causes premature aging in all materials Solution:

  • Proper slope for drainage (minimum 1/4" per foot)
  • Adequate spacing between boards
  • Keep debris cleared from between boards

3. Tree Coverage

Impact:

  • Pros: Shade protects from UV damage
  • Cons: Leaves, sap, and moisture accumulation Solution:
  • More frequent cleaning under trees
  • Consider composite for easier maintenance

4. Usage Intensity

Impact: Heavy furniture, grills, kids' toys all cause wear Solution:

  • Use furniture pads
  • Grill mats to prevent grease stains
  • Regular cleaning

5. Quality of Installation

Impact: Poor installation shows up in years 2-4 Solution:

  • Hire experienced professionals
  • Ensure proper fastener spacing
  • Verify structural adequacy

The Surprising Truth About Deck Aging

After visiting dozens of our completed projects, here's what surprised us:

1. Well-Built Decks Look Great Regardless of Material Whether composite or wood, proper construction matters more than material choice for longevity.

2. Maintenance Compliance is Everything The best pressure-treated deck with no maintenance looks worse than an average composite deck after 3 years.

3. Clients Care Less About Fading Than We Expected Several homeowners said, "Yes, it's lighter than when new, but we don't notice it anymore."

4. The Details Matter Fascia boards, stair nosing, and railings show wear faster than deck boards. Budget for quality here. 

 

What We Recommend for Maryland/Virginia Climate

Based on 3-5 year performance data:

Best for Most Homeowners: Mid-to-high-end composite (Trex Transcend, TimberTech, Fiberon)

  • Reason: Minimal maintenance, excellent longevity, good appearance

Best for Budget-Conscious: Pressure-treated with annual maintenance commitment

  • Reason: Lower upfront cost, can look excellent with care

Best for Premium Appearance: High-end composite (Azek) or Ipe with maintenance commitment

  • Reason: Unmatched appearance, worth the investment if budget allows

What We Don't Recommend:

  • Low-end composite (shows wear quickly)
  • Cedar or redwood (doesn't perform well in our humid climate)
  • Exotic hardwoods other than Ipe (mixed results)
