Masonry services in Hilo, HI

Mainstay Hilo Concrete and Masonry does 16 kinds of masonry work in Hilo, HI, from worn joints and cracked walls to new walls and paving. Price usually turns on the size of the job, the material you pick and how much damage sits behind what you can see. The schedule turns on whether a permit or an engineer is part of it, and your estimate puts your scope in writing.

  • When a foundation wall cracks or shifts, we find out what's moving it, then repair the block or concrete so the wall carries the house again.

  • Chimney repair for loose brick, cracked caps and failing joints, worked from the top down so water has fewer ways into the stack.

  • Tuckpointing replaces worn mortar across a whole wall, ground out and refilled, then finished with a fine line so the joints look sharp and even.

  • We replace cracked, broken or loose bricks one at a time and match the new ones to your wall in size and color as closely as we can find.

  • For homeowners who want a new drive, we lay pavers over a packed, graded base, so a damaged section can be lifted and relaid later.

  • We build block and stone retaining walls for sloped yards, with drainage behind them so water has a way out instead of pushing on the wall.

  • For older brick and stone that's stained, cracked or crumbling, we repair the joints and the masonry itself so the wall works and looks right again.

  • We build masonry fireplaces in brick or stone for homeowners adding one, laid out to fit the room and finished clean around the firebox and hearth.

  • Stone veneer is a thin face of stone set over block or framing, for the look of stone on a foundation, column or house wall.

  • We build concrete block walls for property lines, yards and outbuildings, laid straight and level, with steel and filled cores where the wall needs them.

  • For new homes and additions, we lay the block foundation walls the house sits on, checked against the plans row by row as they go up.

  • We build outdoor kitchen counters, grill surrounds and bases in block, brick or stone for homeowners who like to cook and eat outside.

  • From the drive to your front door, we build walkways in pavers, brick, stone or concrete, sloped to shed rain and set on a packed base.

  • New brick walls for gardens, planters and entries, laid on a solid footing with the joints finished clean and even, for homeowners who want brick that lasts.

  • Natural stone walls, steps and columns, with each stone fitted and set in mortar by hand, for homeowners who want solid stone all the way through.

  • If the mortar between your bricks is cracked or missing, we clean out the bad joints and refill them with mortar suited to the brick.

  1. Call or send the form

    Call (808) 229-1042 or fill out the form and tell us what you're seeing, where it is on the property and roughly how big it is. We reply within one business day to set a time for me to come out. The estimate is free, and there's no pressure to book.

  2. I look it over and write it up

    I come out myself, measure and work out why it failed or what the site needs before I put a price on anything. You get a written estimate that lays out the scope, the materials and the steps. If a permit or an engineer is part of the job, I tell you that up front.

  3. Our crew builds it

    Our own crew does the work, and I run it on site, so what you approved is what goes up. If a permit is needed, we take care of the county paperwork and tell you where it stands before we start. If opening things up shows more than we could see at the estimate, we show you and talk it through first.

  4. We walk it together

    When the work is done, I walk it with you before we call it finished. You see the joints, the lines and the drainage for yourself, and we clean up the site before we leave. The work is backed by our satisfaction guarantee.
