Why nobody can price a porch over the phone
Two porches with the same square footage can differ enormously in price. One is a screen enclosure under an existing roof on a deck that already exists. The other is a new gable roof tied into a two-story wall, on new footings, with a tongue-and-groove ceiling and a masonry fireplace. Same footprint, entirely different job.
When a contractor gives you a per-square-foot number before seeing the site, they are either quoting the cheapest possible version or padding for the worst case. Neither helps you plan. Every project is priced after an on-site visit — we don't quote lake work off a photo.
The five decisions that move the number most
In order of impact on almost every project we build around Lake Murray:
Roof structure — reusing an existing roof is far cheaper than framing a new one and tying it into the house correctly with proper flashing.
Foundation and grade — a flat backyard takes standard footings; a lot that drops eight feet toward the water needs deeper piers, taller posts and sometimes retaining work first.
Screen system — standard fiberglass screen, a heavier pet-resistant mesh, motorized retractable screens and EZE-Breeze vinyl panels sit at very different price points.
Ceiling and finishes — an exposed painted frame costs a fraction of stained tongue-and-groove with recessed lighting and a fan.
Extras — an outdoor kitchen, fireplace, sound, heaters or a full electrical package can equal the cost of the shell itself.
Where homeowners regret saving money
The two cuts we see people regret are ceiling height and the size of the seating area. Dropping the roof pitch to save framing dollars makes a porch feel like a hallway, and it can't be fixed later without rebuilding. Shrinking a porch by two feet to hit a number usually means the furniture you already own doesn't fit around a table.
Screen material is the opposite — starting with standard screen and upgrading later is easy, because the frame doesn't change.
How we build the estimate
We visit, measure, photograph the roofline and grade, and talk through how you actually plan to use the space. You get a written scope that names materials and a fixed price — not an allowance sheet that drifts upward for three months.
If a project is going to require shoreline setback review or an HOA submittal, we tell you that on the first visit rather than after a deposit.
