TimberTech Certified Installer
Why TimberTech Certified Matters for Your Deck
Not every contractor can install TimberTech, and that’s the point. To become certified, Arch Exteriors had to demonstrate an active state contractor’s license, current general liability insurance, and proven installation expertise. That vetting process exists to protect you.
As a TimberTech certified installer, we have direct access to the full product line — including composite and Advanced PVC decking. Along with factory installation training, so every board goes down exactly as the manufacturer intended. That’s what unlocks the warranties most contractors can’t offer.
What TimberTech Composite Decking Gives You
- Low Maintenance: No staining, sanding, or repainting ever. TimberTech cleans with soap and water and won’t fade, splinter, or peel.
- Sustainably Made: TimberTech composite is made from up to 85% recycled material TimberTech, diverting plastics and wood waste from landfills, without sacrificing performance.
- 30+ Colors & Textures: More than 30 real wood colors and textures are available TimberTech, from natural grain styles to painted finishes, at a range of price points.

Custom Decking Options for Every Style & Budget
Your home is one of a kind. Your deck should be too. At Arch Exteriors, we don’t do cookie-cutter. We start by understanding how you want to use your outdoor space, then design a deck that fits your home’s architecture, your yard’s layout, and your budget.
We work with three primary decking materials, each with its own advantages:
- Composite: The most popular choice for Maryland and Virginia homeowners. Low-maintenance, durable, and available in dozens of realistic wood tones. As a TimberTech certified installer, we offer composite decking backed by warranties of up to 30 years.
- Advanced PVC: TimberTech’s highest-performing material. Won’t fade, stain, splinter, or peel, and stays up to 30° cooler to the touch than competing composite boards. Backed by a Lifetime Limited product warranty and a 50-year fade and stain warranty.
- Wood: A classic for a reason. Pressure-treated pine and cedar remain popular for their natural look, lower upfront cost, and the flexibility to stain or paint to your preference.
Know Your Options Before You Build
Composite Decking
The sweet spot between performance and price. Composite boards are made from a blend of wood fiber and recycled plastic, giving you a natural wood look without the upkeep. A strong choice for families who want a beautiful deck without committing to annual maintenance.
- Cost: Mid-range
- Maintenance: Low. Occasional soap and water cleaning
- Warranty: Up to 30 years (product + fade & stain)
- Eco-friendly: Made from up to 85% recycled materials
- Best for: Everyday use, families, budget-conscious homeowners
Advanced PVC Decking
TimberTech’s highest-performing material, and the one we recommend for homeowners who want the absolute best. 100% engineered polymer with no wood content means it’s completely impervious to moisture, insects, and rot. It also stays cooler underfoot than competing composites.
- Cost: Premium
- Maintenance: Minimal. Won’t fade, stain, splinter, or peel
- Warranty: Lifetime Limited product warranty + 50-year fade & stain
- Temperature: Stays up to 30° cooler than competing composites
- Best for: Long-term investment, high-use decks, hot summers
Wood Decking
The traditional choice, and still a great one for the right homeowner. Pressure-treated pine offers affordability and structural strength, while cedar brings natural beauty and moisture resistance. Wood decks can be stained or painted to match any style, but they do require more consistent upkeep than composite alternatives.
- Cost: Lower upfront
- Maintenance: High. Staining, sealing, and inspections needed annually
- Warranty: Varies by species and treatment
- Customizable: Stain or paint to any color
- Best for: Traditionalists, lower budgets, homeowners who enjoy upkeep

FAQs
How much does deck installation cost in Maryland or Virginia?
Deck installation costs vary depending on several factors: deck size, material choice (wood, composite, or Advanced PVC), ground-level vs. multi-level design, railing type, and permit fees. As a general range, homeowners in Maryland and Virginia typically invest between $15,000 and $45,000 for a professionally installed deck. The best way to get an accurate number for your specific project is a free in-home estimate, where we can assess your yard, discuss your goals, and give you a real figure, not a ballpark.
Do I need a permit to build a deck in Maryland or Virginia?
In most cases, yes. Both Maryland and Virginia require a building permit for deck construction, particularly for attached decks or any structure above a certain height or square footage. Requirements vary by county, so the rules in Montgomery County differ from those in Fairfax County, for example. At Arch Exteriors, we handle the permitting process on your behalf — so you don't have to navigate county regulations on your own.
What is the best decking material for Maryland and Virginia summers?
Heat and humidity are real considerations in this region. Wood decks require more maintenance in humid climates — staining and sealing annually to prevent moisture damage and warping. Composite and Advanced PVC hold up significantly better in Mid-Atlantic weather conditions. TimberTech's Advanced PVC line in particular is engineered to stay up to 30° cooler to the touch than competing composites, which is worth considering if your deck gets direct afternoon sun.
