- Deck rates are installed prices (labor plus materials) from area builders, with the frost-depth footings the state building code requires already baked in — national deck figures that assume shallow footings undershoot here.
- Elevated decks multiply the decking line by 1.35 — the midpoint of the local 25–45% premium for extra posts, beams, and staging.
- Finish-carpentry rates are national figures with a ~25% local labor uplift applied: crown $9–$20 per lf, baseboard $9–$11, prehung interior doors $650–$1,000 each, built-ins $375–$1,500 per lf.
- The finish quantity follows the item — linear feet for molding, baseboard, and built-ins, door count for prehung doors.
- Small trim jobs carry a $300–$500 practical minimum; setup and finish time dominate below that.

What drives the price
Decking material sets the budget
Pressure-treated pine runs $25–$45 per sq ft installed, cedar $38–$55, composite $50–$68, and PVC or Ipe $65–$85. The framing underneath is the same lumber either way — the spread is the boards, railings, and trim you see and touch, which is why material is the first question any South Shore deck builder asks.
Height, stairs, and what the site demands
An elevated deck adds roughly 35% for taller posts, beefier framing, and staging. A stair set to grade is its own $1,400–$2,600 line, and code guardrail runs $30–$60 per linear foot. Two decks with identical square footage can land thousands apart on these three items alone.
Finish work is priced per piece, graded by material
Trim carpentry quotes by the item: so much per foot of crown or baseboard, per door, per foot of built-in. Within each item, material grade drives the band — paint-grade poplar or MDF at the bottom, stain-grade hardwood at the top — and old, out-of-plumb walls add scribing time that shows up as the high end of the range.
Carpentry labor in South Shore
Finish-carpentry rates here run about 25% above the national figures most cost articles quote, in line with the region's premium across the trades. The deck figures are local to begin with — including the frost-depth footings Massachusetts code requires — so the estimate above shouldn't need mental markup.

Request coverageCarpentry Work cost questions, answered
- How much does it cost to build a deck in South Shore?
- A 200 sq ft pressure-treated deck with railings, a stair set, and the permit typically lands around $8,000–$14,500 in South Shore; the same deck in composite runs roughly $13,000–$19,000. Even a modest ground-level platform rarely comes in under $5,000, because frost-depth footings — required by code in Massachusetts — are baked into local per-foot rates.
- Is composite decking worth the extra cost over pressure-treated?
- Composite installs at roughly $50–$68 per sq ft against $25–$45 for pressure-treated — call it $5,000–$7,000 more on a 200 sq ft deck. What you're buying is the maintenance delta: pressure-treated wants staining or sealing every couple of seasons, composite needs a wash. If you'd be paying someone to do that staining, composite usually pencils out over the deck's life; if you enjoy the work, treated pine keeps winning on price.
- Do I need a permit to build a deck in Massachusetts?
- Yes — a deck is a structure, and the building permit runs $150–$500 in the South Shore area depending on the town and project value. The inspector checks footing depth (they must reach below the frost line), the ledger attachment to the house, and railing height. Treat a contractor who suggests skipping the permit as a red flag: unpermitted decks surface at appraisal and home sale, and fixing paperwork after the fact costs more than the permit ever did.
- How much does crown molding or baseboard cost to install?
- Figure $9–$20 per linear foot for crown molding installed in the South Shore area and $9–$11 for baseboard — material plus labor, with paint-grade profiles at the low end and hardwood or built-up profiles at the top. A typical 12×14 room needs about 52 linear feet, so crown for one room lands around $470–$1,040. Small trim jobs carry a practical minimum of $300–$500, since setup and caulk-and-fill time don't shrink with the room.
- What do custom built-ins cost?
- Built-in shelving and cabinetry runs $375–$1,500 per linear foot installed in the South Shore area — the wide spread is paint-grade MDF open shelving at the bottom versus furniture-grade hardwood with doors, drawers, and lighting at the top. A typical 8-foot wall unit lands between $3,000 and $12,000. These are national figures with the roughly 25% local labor uplift applied, so expect quotes here to run above what national cost articles suggest.
