The 10 Best General Contractors in Charleston (2026)
This list ranks the best general contractors and construction firms in Charleston using a Google-review‑based methodology updated for 2026. We order businesses by a Bayesian-style score that balances average rating with review volume so smaller shops with perfect scores don’t automatically outrank well-reviewed firms with more feedback. Charleston’s building market blends historic renovation and coastal construction demand, so property owners often look for contractors who can navigate permits, flood-zone concerns, and local materials. Use this guide as a starting point to compare public ratings and find firms to contact for estimates and references.
This ranking is computed from Google reviews (our method). Listings marked Partner are paid advertising spots: they sit alongside the ranking without changing its order.

Confirm the contractor’s license and insurance coverage, ask for a list of recent local references, and request a written contract that spells out scope, schedule, payment terms, and change-order procedures. Also check how they plan to handle permits and inspections.
