Pittsburgh's Trusted Deck Builder & Fence Contractor

Deck Builder & Fence Contractor in Pittsburgh, PA

A custom deck or fence from Abes Contracting transforms your Pittsburgh backyard into a true outdoor living space. Since 2019, we’ve built hundreds of decks and installed miles of fencing across Allegheny County—from ground-level pressure-treated platforms in Bethel Park to elaborate multi-tier composite decks overlooking Pittsburgh’s spectacular hillside views in Mt. Washington, Duquesne Heights, and Fox Chapel. We understand Pittsburgh’s terrain, climate, and building codes better than any contractor in the region.

Outdoor structures in Pittsburgh face genuine environmental challenges. Our winters bring ice, snow loads, and freeze-thaw cycles that stress footings, posts, and structural connections. Our summers deliver humidity, UV, and thunderstorms that accelerate wood weathering and can cause rot if not properly addressed. Our springs bring the heaviest rainfall and soil saturation that test drainage around posts and footings. We build every deck and fence with Pittsburgh’s conditions in mind—using proper post depth below frost line (typically 36–42 inches in Allegheny County), drainage-friendly backfill, quality hardware, and appropriate materials for each application.

Deck Construction in Pittsburgh: Material Deep Dive

Pressure-Treated Lumber: The most affordable decking option, pressure-treated southern yellow pine is the workhorse of Pittsburgh deck construction. Modern ACQ (alkaline copper quaternary) treatment is safe, long-lasting, and handles Pittsburgh’s moisture and freeze-thaw cycles well. Requires staining/sealing every 1–3 years to maintain appearance and prevent checking (surface cracking). Properly maintained, a pressure-treated deck lasts 15–20 years. Most budget-conscious projects in Bethel Park, McCandless, and similar markets choose pressure-treated.

Composite Decking (Trex, TimberTech, Fiberon): Premium composite products have improved dramatically and now dominate the mid-to-high end of Pittsburgh’s deck market. Modern capped composite boards resist staining, fading, scratching, and moisture. They won’t splinter, require no staining or sealing—just occasional soap-and-water cleaning—and come with 25–30 year warranties. For families with children and pets, or for homeowners who want a beautiful deck without ongoing maintenance, composite is the clear choice. TimberTech Azek (PVC-based) is our recommendation for Pittsburgh because it’s the most moisture-resistant option available.

Cedar and Redwood: Naturally rot-resistant woods that offer genuine beauty and character. Cedar is locally available and popular for privacy fences and decks where natural aesthetics are a priority. It requires regular staining/sealing but takes finish beautifully. More expensive than pressure-treated but less than composite.

Pittsburgh Deck Permits — What You Need to Know

Almost every deck in Allegheny County municipalities requires a building permit if it’s attached to the house or elevated more than 30 inches above grade. Permit requirements vary by municipality—the City of Pittsburgh, Mt. Lebanon, Bethel Park, and McCandless each have their own submittal requirements and fees. We handle the complete permit process: drawings, applications, fee submission, and coordination with inspectors. Decks built without permits are a significant problem in real estate transactions—unpermitted decks must often be torn down or retroactively permitted (sometimes requiring extensive structural upgrades). Always use a contractor who pulls permits.

Structural requirements for Pittsburgh decks include: footings poured below the 36-inch frost line (deeper in some areas), proper ledger board connection to the house with code-approved hardware (lag screws or through-bolts with flashing to prevent water intrusion), post bases that keep wood off concrete, and guardrails on any deck 30 inches or more above grade. Our decks meet or exceed all Pennsylvania Uniform Construction Code (UCC) requirements and are inspected at rough framing and final completion.

Fence Installation in Pittsburgh: Navigating Local Regulations

Fence installation in Pittsburgh-area municipalities involves more regulatory complexity than most homeowners realize. Many communities in Allegheny County have zoning ordinances that regulate fence height (typically 4 feet in front yards, 6 feet in rear yards), setback from property lines, and material restrictions. Some neighborhoods—particularly older communities with HOAs or historic districts—have additional aesthetic guidelines. Before installing any fence, we verify your local zoning requirements, pull any required permits, and in some cases recommend property line surveys to ensure the fence is correctly positioned.

Privacy fences are the most requested in Pittsburgh suburbs where properties are closely spaced. Six-foot wooden privacy fences in treated pine or cedar are extremely common in South Hills neighborhoods like Bethel Park, Mt. Lebanon, and Castle Shannon where backyards abut neighboring properties. Vinyl privacy fences have grown in popularity for their maintenance-free longevity—a quality vinyl fence installed properly with steel-reinforced posts should last 20–30 years without painting or staining. For front yards and streetscapes, decorative picket fences and ornamental aluminum are more appropriate and often required by local ordinance.

Multi-Level Decks for Pittsburgh’s Hillside Properties

Pittsburgh’s iconic hillside topography creates unique opportunities for dramatic multi-level outdoor spaces. Properties in areas like Mt. Washington, Duquesne Heights, Ben Avon Heights, Aspinwall, and the elevated sections of Fox Chapel and Sewickley often have significant grade changes that would render a standard flat deck impractical. Multi-tier decks solve this elegantly—creating distinct zones at different elevations connected by stairs, maximizing usable space while working with natural topography rather than against it. We’ve designed and built complex multi-level structures on slopes exceeding 30 degrees, always with proper engineering review and structural footings that handle both vertical and lateral loads.

Deck and Fence ROI in Pittsburgh’s Real Estate Market

A well-built deck adds genuine value to Pittsburgh homes. According to national data, wood decks return approximately 65–70% of cost at resale, while composite decks return 60–65% (higher upfront cost, but buyers love the low maintenance). In Pittsburgh’s competitive suburban markets—Fox Chapel, Sewickley, Mt. Lebanon, Upper St. Clair—an attractive outdoor living space has become an expectation rather than a luxury. Homes without outdoor entertaining areas often sell for less or sit longer on the market. A $15,000–$25,000 composite deck investment can add $12,000–$18,000 in appraised value while providing years of enjoyment before you sell.

Privacy fences add value in specific contexts—particularly in urban and suburban Pittsburgh neighborhoods where privacy from neighbors and noise reduction from nearby roads is valued. Homes in Bethel Park, Dormont, and Scott Township near Route 19 or other busy corridors often see fence installation as a quality-of-life investment that also makes the property more appealing to buyers with children or pets.
