Outdoor Space That Holds Up Year-Round


Custom Decks and Porches in Greenwood, SC and Surrounding Areas

If you have a yard in Greenwood, Greenville, Anderson or a surrounding area with a slope, a view, or room to extend your living space outdoors, a well-built deck or porch makes that area usable in ways a patio or lawn can't match. South Carolina's humidity, sun exposure, and seasonal rain mean the structure needs to be framed, fastened, and finished with materials that won't warp, rot, or pull apart after a few seasons. Advanced Terrain Management builds decks and porches that stay level, drain properly, and handle the climate without constant maintenance or early replacement.


We design and construct new decks and covered porches for homes with large yards, scenic views, or uneven terrain that makes ground-level outdoor space impractical. The work includes site prep, post installation, framing, decking, railing, and stairs, all built to code and engineered for load and weather exposure. Whether you're replacing an old structure or adding something new, the goal is usable square footage that extends how you use your property and adds curb appeal without becoming a maintenance burden.


If you're ready to add outdoor living space or replace a deck that's no longer safe, get in touch to plan your project in the Greenwood area.

What Gets Done During Site Preparation

Construction starts with setting posts in concrete footings below the frost line, which keeps the structure stable even on sloped or clay-heavy soil common in the Greenwood area. We use pressure-treated lumber for framing, galvanized or coated fasteners to prevent rust, and joists spaced to support foot traffic and furniture without bounce or sag. Decking material options include treated pine, composite, or PVC, depending on your budget and how much upkeep you want to do over time.


Once the deck is finished, you'll have a flat, stable surface that doesn't shift when you walk across it, railings that meet code height and spacing requirements, and stairs that feel solid and even. Water will shed off the boards instead of pooling, and fasteners will sit flush so nothing snags bare feet or furniture legs.


Porches can be built with hip or gable roofs, ceiling fans, and recessed lighting, and we tie the roofline into your existing structure so it looks intentional rather than added on. If your yard has drainage issues or uneven ground, we handle grading and site prep before framing begins. We don't install decorative features that compromise structural integrity, and we pull permits where required so the work is inspected and documented.

Homeowners usually want to know how material choice affects longevity, whether a permit is required, and what site conditions mean for cost, so we've outlined the most common concerns below.

Common Questions Before You Build

What decking material lasts longest in South Carolina?
Composite and PVC decking resist moisture, fading, and insect damage better than wood, and they don't require staining or sealing. Pressure-treated pine costs less upfront but needs regular maintenance to prevent rot and splintering in humid climates.
How deep do footings need to be?
Posts are set in concrete footings at least 12 inches below grade, deeper if the soil is loose or the deck is elevated. This keeps the structure from shifting or sinking over time, especially on sloped or clay-heavy lots.
Why does joist spacing matter?
Joists spaced too far apart create bounce and allow decking to sag or crack under weight. We follow code spacing based on your decking material and span, so the surface stays solid and the boards don't cup or warp between supports.
What's the difference between a deck and a porch?
A deck is an open platform, usually elevated, with railings and no roof. A porch is covered, often attached to the front or back of the house, and may include posts, beams, and a tied-in roofline for shade and weather protection.
When do I need a building permit?
Most counties in South Carolina require a permit for any deck over 30 inches high or attached to the house. We handle the permit application and coordinate inspections so the project stays on schedule and meets code.
