    Is your mason booked until spring?

    Worried about dust in your client's home?

    Cutting stone indoors spreads fine dust through an occupied house, and the homeowner blames you, not the sub.

    Cut outside or wet-cut with a vacuum, seal the room, and leave it clean every day.

    1. Room sealed, floors covered
    2. Cut outside or wet-cut with vacuum
    3. Cleanup every day
    4. Professional standard of cleanliness

    Does your sub go quiet mid-job?

    Subs who vanish for days, don't coordinate with your trades, or hand your client a business card.

    Email updates at every milestone. We never solicit your client.

    1. Email at every milestone
    2. Online schedule tool you can check anytime
    3. Before and after photos

    What we build inside

    Fireplace elevation drawing

    Fireplace surrounds and hearths

    Stone, thin stone, thin brick or full brick. Raised hearths, hearth slabs and mantels. We check clearances with your fireplace installer before we set a stone.

    Stone accent wall drawing

    Stone and brick veneer walls

    Basement bars, media walls, range-hood walls, stair walls.

    Thin brick close-up

    Old brick, restored

    We expose, repoint and seal the original brick your remodel uncovers.

    We don't do foundation repair or basement waterproofing. We'll tell you who does.

    Zero friction

    Our goal: the easiest masonry sub you have ever hired.

    One text reaches the owner. Paperwork shows up before you ask. The crew starts when promised, leaves the room clean, and never talks to your client about anything but the wall.
