Frequently Asked Questions

Capped composite has a wood-fiber core wrapped in a protective polymer shell, while solid PVC is uniform polymer throughout with no wood content. Capped composite offers more realistic wood texture and slightly higher strength, whereas solid PVC provides maximum moisture resistance and won't absorb water at cut edges. Both resist fading and insects, but PVC expands more in heat.

Charlotte's humid summers and temperature swings accelerate wood moisture absorption, causing expansion and contraction that leads to cracking and warping. Pressure-treated pine requires annual cleaning and sealing to prevent mildew growth in humid conditions. Cedar naturally resists moisture better but still benefits from UV-protective sealers to prevent graying from intense summer sun exposure.

If joists and beams remain solid and only surface boards or railings show damage, repair extends deck life cost-effectively. Structural inspections reveal whether foundation posts, ledger boards, and framing meet current load requirements. Decks under 15 years old with isolated rot or cosmetic damage typically justify repair, while widespread joist decay or code violations often require replacement.

Pergolas use open rafters spaced for partial shade while deck covers have solid roofing that blocks rain. This design difference affects foundation requirements—pergolas need fewer supports because wind passes through the structure. Attached pergolas anchor to house fascia and footings, while freestanding versions require four or more concrete piers based on span and height.

Composite materials eliminate ongoing sealing, staining, and board replacement that wood requires every 2-3 years. The capped polymer shell resists moisture and UV damage that degrades wood over time. While upfront composite costs run 2-3 times higher, maintenance savings and 25+ year lifespans often offset the difference compared to wood's 10-15 year replacement cycle.

Proper joist spacing allows water runoff between boards, while flashing tape seals the tops of beams and joists from moisture penetration. Sloped framing directs water away from the ledger board attached to the house. Galvanized joist hangers and stainless fasteners resist corrosion in areas where wood stays damp, particularly near ground level and around posts.

Shadowbox fences alternate pickets on both sides of rails, creating a dimensional pattern visible from either direction with narrow sight gaps. Privacy fences place pickets tight together on one side only, blocking visibility completely. Shadowbox designs allow some airflow while maintaining screening, whereas solid privacy fences provide maximum enclosure but require stronger framing to handle wind load.

Installation includes setting gate posts in concrete footings sized for gate weight and wind resistance, mounting the gate operator with arm or chain drive mechanism, running power to the operator location, and programming access controls. Safety features like photo eyes prevent closure on vehicles or people. The process also involves configuring remotes, keypads, or smartphone controls based on homeowner preferences.

Lower-grade vinyl becomes brittle in freezing temperatures and can crack from impacts, while premium vinyl formulations maintain flexibility below freezing. UV inhibitors in quality vinyl prevent sun degradation that makes material more vulnerable to cold-weather cracking. Posts set in proper concrete footings handle ground freeze-thaw movement better than shallow installations where frost heave stresses the material.

Most jurisdictions around Charlotte require 4-foot minimum height with self-closing, self-latching gates that open outward from the pool area. Picket or rail spacing must prevent a 4-inch sphere from passing through to stop young children from squeezing between. Aluminum fencing often meets these requirements while maintaining visibility for supervision, though specific codes vary by municipality and should be verified during planning.

Cedar contains natural oils that resist insects and decay without chemical treatment, but costs 2-3 times more than pressure-treated pine. Both species last 15-20 years with proper maintenance, though cedar requires less frequent sealing. Pressure-treated pine accepts stain more evenly and handles ground contact better due to deeper chemical penetration, making it preferable for posts and structural framing.

Shallow concrete footings let posts shift during ground freeze-thaw cycles, while undersized footings can't resist wind pressure against fence panels. Wood posts in direct soil contact rot at ground level where moisture concentrates. Clay soil common in the Charlotte area expands when wet and contracts when dry, creating movement that loosens posts not set in concrete extending below the frost line.
