Custom outdoor fire pitsin Woburn, MA
Round, square and custom fire pits in block and natural stone, designed and built into the patio around them for homes in Woburn and greater Boston.
A fire pit people actually gather around.
Gerrior Masonry & Landscape is a fire pit builder in Woburn, MA, designing and installing custom outdoor fire pits for homes across greater Boston. In more than 30 years of hardscaping we have built paver and stone fire pits along with the patios and seat walls around them.
We help you choose the size, material and color, then build the pit on a proper base with the liner it needs to handle heat and frost. Owner Joseph Gerrior oversees the work, and we are fully insured and guarantee what we build.

Fire pit options
The classic circle, with seating all the way around and everyone the same distance from the fire.
Clean-lined square pits for a modern patio, or a shape made to fit your layout.
Lined with a steel fire ring or fire-rated material so the heat doesn't crack the stone.
Easy lighting and no ash, with the gas line run by a licensed gas fitter.
Curved block or fieldstone seat walls that give built-in seating and block the wind.
A new paver patio built around the fire pit, sized for the chairs that go with it.
How we build a fire pit that lasts
Matching the fire pit to the patio, picking a shape, what goes inside it, adding one to an existing patio, and the questions to settle before you build.
Built to match the patio it sits on
A fire pit looks best when it looks like it was always part of the yard. We build ours from the same family of materials as the patio, seat walls and steps around it: Unilock wall block in a color that suits the pavers, round New England fieldstone for a more natural look, and granite or block caps on top. On the Stoneham patio on our patio design and installation page, the round fire pit is built in a block that matches the curved seat wall behind it, so the two read as one piece.
Round, square or a custom shape
- Round. The classic choice. Everyone sits at the same distance from the fire, and chairs arrange themselves naturally in a circle.
- Square. A more modern, structured look with clean lines, like the square fire pit beside the pool on our Lynnfield job.
- Custom shapes. A fire pit sized or shaped to fit a particular patio, garden or seating layout.
We'll help you pick the size, material and color that fit your space when we meet you at the house.
What's inside a fire pit that lasts
From the outside a fire pit is a ring of stone, but most of what decides how long it lasts is hidden. It sits on a compacted base like the patio around it, so it doesn't heave and crack apart after a few winters. A wood-burning pit is lined with a steel fire ring or fire-rated material, because direct heat cracks ordinary wall block over time. The bowl needs a way for rain to drain out instead of sitting in the bottom and freezing. And the cap is set so it sheds water rather than letting it into the joints.
Adding a fire pit to an existing patio
If you already have a paver patio, it may be possible to add a fire pit to it; we can look at yours at the estimate. Typically the pavers where the pit will sit are lifted, a base is prepared, and the pit is built and tied back into the surrounding pavers, which look better and last longer than a pit simply set on top. If the patio is old, sinking or too small for chairs around a fire, it may make more sense to rebuild or extend the patio at the same time.
Seat walls and seating around the fire
Seating is what makes a fire pit get used. Plan the patio around the ring of chairs, not just the pit itself, so nobody ends up with their back against a railing or their chair half on the lawn. A curved seat wall on one side of the fire gives built-in seating that never needs to be put away, and it shields the fire from the wind. The fire pits in our patio and fire pit photos include several with fieldstone and block seat walls.
Wood or gas
Wood-burning fire pits give real heat and the smell of a fire; they also give smoke and ash to clean out. Gas fire pits light with a switch and leave no ash. A natural gas fire pit needs a gas line from the house, which in Massachusetts has to be run by a licensed gas fitter, and a propane pit needs a spot for the tank. If you might want gas, it's easiest to plan before the patio is built. Our backyard fire pit guide compares the two in detail.
Placement and town rules
Where the fire pit goes matters for safety as much as for looks: clear of the house, overhanging trees and fences, and somewhere the smoke won't blow straight into the windows. Towns and fire departments around Massachusetts have their own rules on backyard fires, so check yours before you settle on wood. The backyard fire pit guide covers placement and the local rules.
What decides the price
The price of a fire pit depends on the size, the shape, the material, whether it is wood-burning or gas, and whether it is part of a new patio or added to an existing one. Seat walls and the patio around a fire pit usually cost more than the pit itself. Our paver patio cost guide explains what moves the price of the patio around it. The visit and the estimate are free, and you get a price before any work starts.
Fire pits we have built.
In Lynnfield, the square fire pit at the top of this page sits on a large-format paver deck beside the pool, with Adirondack chairs around it and the planting beds behind. The whole job is on the Lynnfield project page.
In Stoneham, a round block fire pit sits in the curve of a matching seat wall on a backyard patio. The photo here shows another round fire pit being finished on a new paver patio, with the fieldstone seat wall already built behind it.

How a fire pit project runs
We meet you at the house, look at where the fire pit could go and how you'll sit around it, and talk about wood or gas.
You choose the shape, size and material, plus any seat wall or patio, and you get a price before anything starts.
Dig Safe marks the utilities, the base is built and compacted, and the pit is laid out at its final spot.
The walls go up course by course with the liner and drainage, the cap is set, and the patio is tied in around it.
Outdoor fire pits, answered
01Can you add a fire pit to my existing patio?
Often it can be, depending on the patio. We'll look at yours at the estimate. If the patio is old or too small for seating around a fire, extending or rebuilding it at the same time may make more sense.
02Do you build gas fire pits?
Yes. We build the fire pit, and the gas line from the house is run by a licensed gas fitter, as Massachusetts requires. Propane is another option where a gas line isn't practical.
03Why does a wood-burning fire pit need a liner?
Direct heat cracks ordinary wall block and some stone over time. A steel fire ring or fire-rated lining takes the heat, so the outside of the pit stays sound.
04What shape of fire pit should I choose?
Round pits suit conversation and seating all the way around. Square pits suit a modern patio. A custom shape can fit an unusual space. We'll show you what fits your patio when we visit.
05Am I allowed to have a wood fire pit in my town?
Rules on backyard fires vary by town and fire department in Massachusetts, so check with yours before you settle on wood-burning. Our backyard fire pit guide explains what to look for.
06Do you build seat walls around fire pits?
Yes. A curved seat wall in block or fieldstone gives built-in seating, blocks the wind and frames the fire, and it's built on the same base as the patio.
