Seat Wall and Pillars — Block Columns With Caps and Pillar Lights
Pillars that mark the corners and the steps, with a light on top and a seat wall running between — stacked plumb on a base so the caps stay level.
Seat wall and pillars are block columns built at the ends of a seat wall or either side of a patio opening, capped and often lit. JMB Builders builds them across the Twin Cities metro and north to St. Cloud on new and existing patios, with a conduit sleeve up the core so a licensed electrician can wire a pillar light. Pillars priced per unit, wall per linear foot, quoted from your photos, with a reply within one business day.

Pillars go where a wall ends or a path begins: the ends of a seat wall, the corners of a patio, either side of a set of steps, the mouth of a driveway, a mailbox. They carry a cap and often a light, and they take the hits a wall does not: a shoulder on the way past, a snowblower, a kid climbing. A pillar built on bedding sand tips. A pillar stacked hollow has nowhere to run the light wire. A cap set off center shows from the kitchen window.
The build: a compacted base under each pillar, wider than the pillar, and a small footing where the pillar is tall or carries a gate. The block lines sell pillar units or corner units that stack into a column; they go up plumb and glued, and the cores are grouted solid with a conduit sleeve run from the base to the cap for the light wire. The cap is glued on centered and drilled for the fixture base. A seat wall between pillars goes on the same base, and on an existing patio the pavers are lifted and cut tight to the pillars.
The light is the electrician's part. Low voltage from a transformer or line voltage, the wire comes through the sleeve we left and the fixture mounts to the cap; both the transformer and the wiring are done by a licensed electrician once the caps are on. Driveway pillars sit back from the pavement with the plow in mind, and their caps are glued like every other.

How it is priced: per unit
Quoted in writing from your photos, with a reply within one business day. What moves the number:
- Number of pillars and their height
- Block line: a stacked pillar unit vs. a column cut and fit from wall block
- Cap: standard block cap vs. a cut stone cap
- Seat wall between the pillars, priced per linear foot
- Conduit sleeve for a light, with the electrician's wiring as its own line
- New patio under them vs. lifting pavers on an existing patio
Send a photo of the patio or the entrance and say how many pillars and whether you want lights. We quote the pillars per unit from that.
How long it takes
Two pillars on an existing patio: one day. Pillars with a seat wall between: two to three days. The electrician comes after the caps are on.

Situations and options
Pillars at the ends of a seat wall
A pillar a course or two above the wall at each end, capped and lit, with the seat wall caps running into the pillar face. The common layout on a patio edge.
Pillars flanking steps or a walk
A pillar either side of a set of block steps or the start of a walk, with a light on each so the steps read at night.
Driveway entrance columns
A pair of taller pillars at the street end of the drive, set back from the pavement for the plow, on footings, with a sleeve for a light and a mount for a house number.
Mailbox pillar
A single pillar with the mailbox built into the block, on a base set back to the distance the post office wants, capped and glued.
Seat Wall and Pillars — Block Columns With Caps and Pillar Lights: questions, answered
Can you add pillars to an existing paver patio?
Yes. We lift the pavers where each pillar goes, dig and compact a base wider than the pillar, build the pillar, and cut the pavers back tight to it. The joints are re-sanded. If you want lights, the wire route is planned first so the sleeve comes out where the electrician can reach it.
How do you run the wire for a pillar light?
A conduit sleeve goes up through the grouted core from the base of the pillar to the underside of the cap, with a bend at the bottom that comes out below grade. The cap is drilled for the fixture. The licensed electrician pulls the wire through the sleeve and mounts the fixture after the caps are on.
Who wires the lights on patio pillars?
A licensed electrician, whether it is low voltage from a transformer or line voltage from the house. We build the pillar with the sleeve and the drilled cap and leave the wire route open; the electrician runs the wire, sets the transformer or the circuit, and mounts the fixture.
Do pillars need a footing?
A short pillar on a patio sits on a compacted class 5 base wider than the pillar, the same as the wall beside it. A tall driveway pillar, or one that carries a gate, gets a small footing so it does not tip when the gate swings or the plow leans on it. Either way the cores are grouted so the column is one solid piece.
What block is used for landscape pillars?
Most block lines sell a pillar unit or a corner unit that stacks into a square column to match the wall. Where a line has none, a column is cut and fit from the wall block on a saw. The cap is the line's pillar cap or a cut stone slab, glued and centered.
Can the pillars hold a gate or a fence panel?
Yes, when they are built for it. A steel post is grouted into the core as the pillar goes up and the gate hinges or the fence bracket mount to the post, not the block. The pillar gets a footing sized for the gate's weight. Tell us before the pillar is built; a post cannot be added to a grouted core after.
