Flagstone · Salinas, CA

Fitted natural stone patios, paths and steps

A flagstone patio is stone fitted one piece at a time. We build flagstone patios and walkways across Salinas and the Monterey Bay area. The stone can be set in mortar over a concrete slab, or laid dry on compacted base rock. Which one fits depends on the ground, the shade and how the space gets used.

Aguilar and Sons Construction is a licensed general building contractor based in Salinas, holding CSLB license #787101 since 2000. Flagstone rarely goes in alone, so we also build the concrete steps, footings and low walls around it. Hiring one hardscape contractor in Salinas keeps the stonework and the concrete on one plan. Estimates are free, so call or text (831) 262-9943.

What We Handle

  • Natural flagstone patios, paths, landings and steps
  • Mortar-set flagstone over a poured and reinforced concrete slab
  • Dry-laid flagstone over compacted base rock with stone dust or gravel joints
  • Hand cutting and fitting so the joints stay tight and even
  • Cut stone borders that hold a curving path in place
  • Flagstone treads and landings tied into poured concrete steps
  • Grading and drainage so water runs off the stone and away from the house
  • Sealing the stone and the joints once the patio is finished

Mortar-set or dry-laid: two ways to build a flagstone patio

Mortar-set flagstone starts with a concrete slab. We pour the slab with steel in it and let it cure. Then each stone gets set in a mortar bed and the joints get grouted. What you end up with is a hard surface that stays flat underfoot and sheds water.

Dry-laid flagstone skips the slab. We dig out the area and compact base rock in lifts, then screed a bedding layer under the stone. The joints get filled with stone dust or fine gravel. Water drains through them, and a stone that settles later can be lifted and reset.

The ground usually decides. Heavy clay swells and shrinks with the seasons, which is hard on a rigid slab. Access matters too, since concrete can be pumped into a back yard the trucks cannot reach. We look at the grade, the soil and the drainage on site, then say which method we would build.

Fitting a natural stone patio or flagstone walkway

Flagstone arrives in irregular shapes and mixed thicknesses. Fitting it is cutting and sorting work. We lay the pieces out dry, cut the edges so joints stay even, and keep long straight seams from forming. The thickest pieces go where feet land most.

A stone walkway needs an edge or the stone spreads. We run a cut stone border along a curving path to hold the line. Dry-laid work gets a buried edge restraint so the base rock stays where we put it.

Steps and landings are where flagstone and concrete meet. We pour the steps in forms with steel in them, then set flagstone treads and landings on top. Stucco or stone veneer can wrap the risers so the steps match the patio. A low planter wall beside the landing holds the grade back.

Stone patios in the Monterey Bay area: shade, fog and moss

Summers here are cool and foggy instead of hot. The federal soil survey of the coastal dune belt puts the average July temperature near 62 degrees. It gives the frost-free season as roughly 250 to 350 days. Freezing is rare here, so water, shade and salt air are what wear hardscape down.

Flagstone under oaks stays damp all winter. Moss and algae grow on the shaded side of a patio, and wet stone gets slick. For those areas we pick stone with a cleft or textured face, which keeps its grip when wet. The surface gets sloped so water runs off instead of sitting on it.

Stone paving has a long history on this coast. Carmel-by-the-Sea's own historic record describes local chalkrock, known as Carmel stone, used for chimneys, paving and garden walls. The same document calls a paved terrace between the wings of a house the local form of outdoor living. Fitted stone still suits those homes, from the Monterey Peninsula to Santa Cruz and Hollister.

FAQ

Flagstone Questions, Answered

Common questions about flagstone across Salinas and the Monterey Bay area. If yours is not here, call or text and ask.

Call (831) 262-9943

What makes one flagstone patio cost more than another?
Square footage is only the start. Access matters, since stone wheeled through a side gate takes longer than a truck backing up to the yard. Thick stone, tight fitting and a mortar bed over a poured slab all add labor. Tearing out an old surface and fixing drainage move it too.
Should my flagstone be mortar-set or dry-laid?
Mortar-set stone sits in a mortar bed on a reinforced slab, with grouted joints. It stays flat, sweeps clean and works at a door or on steps. Dry-laid stone sits on compacted base rock with gravel or stone dust joints, the way concrete pavers go in.
Our patio is shaded by oaks and stays damp. Will the flagstone get slippery?
Wet shaded stone does get slick, and moss grows on the side that never sees sun. We use a cleft or textured face in those areas. Keeping leaves off the stone and rinsing it once or twice a year handles most of the growth.
Does a flagstone patio need to be sealed?
Sealing is optional on most stone. A penetrating sealer slows staining, keeps mortar joints cleaner and deepens the color a little. It wears off, so stone in sun and rain wants it again every few years. We can seal the patio when the work is done.
Our yard is heavy clay and it slopes. Can flagstone still work there?
Yes, once the base and the drainage are handled. Some lots on the valley floor and the Hollister side sit on heavy expansive clay. It swells when wet and shrinks when dry, and that movement cracks slabs poured on an unprepared base. On a slope we step the patio down in levels with a low wall.
Do we need a permit for a flagstone patio or walkway?
A patio or path at ground level usually does not need a building permit. California's exempt-work list covers walks and driveways no more than 30 inches above the ground beside them. Cities and counties amend that list, and coastal towns can add their own review. The first step is a call to the building department for your address.
