The Stone Masonry Process

  1. Consultation & On-Site Estimate
    • We discuss your vision, inspect existing conditions, and provide an itemized, no-obligation quote. We identify any structural or substrate concerns upfront to avoid surprises.
  2. Material Selection & Design Approval
    • Choose from a curated selection of natural stones (granite, limestone, slate, bluestone) or manufactured products. Review detailed renderings, color samples, and layout diagrams.
  3. Preparation & Subsurface Work
    • Excavate or prepare substrate; install proper drainage, gravel base, or mortar bed. For walls and facades, we confirm level foundation and moisture barrier installation.
  4. Stone Installation
    • Skilled masons meticulously place each stone—dry-stack, mortar-set, or mechanically anchored—ensuring uniform grout joints, proper slope, and consistent color blend.
  5. Detailing & Finishing
    • Apply finishing touches: grout joint tooling, sealants, flashing integration, and any custom carving or decorative work. Clean all mortar residue and polish surfaces where needed.
  6. Quality Inspection & Project Completion
    • Conduct a final walk-through, point out key maintenance steps, and issue your 1-year workmanship warranty. Provide care instructions to maximize the life of your stone investment.
