Electric at $4,495 through to a pellet stove at $15,595. Each is a complete installed price rather than a unit cost with extras discovered later. The calculator lays all six side by side.

Final price quoted in writing before any work.
Installed packages run $4,495 to $15,595. An electric insert is $4,495; a wood-burning insert is $11,995; a gas insert is $12,995; a built-in gas fireplace is $13,695; a wood stove is $13,295; a pellet stove is $15,595. Each figure is the installed price — unit allowance, venting, liner where the appliance needs one, and the electrical or gas subcontractor allowance are all inside it.
Where a subcontractor's actual cost exceeds the allowance, the difference is billed and you are told before it happens. Upgrading to a higher model is charged at the difference in list price only. We do not install customer-supplied units, and the reason is simple: we cannot warranty an appliance we did not source.
This service reads differently on the two halves of Wellesley. In a pre-war house the usual project is an open masonry firebox that has always been more decorative than warm — an insert with a stainless liner turns it into a heat source. In a post-2000 rebuild it is usually a factory-built unit reaching the end of its service life. Either way the flue is evaluated first, and the standards are on our fireplace installation service page.
Measured right, vented right, tested before we leave. Most of what goes wrong with a fireplace installation was decided before anything was lit — a flue that was never sized to the appliance, a liner that was skipped, clearances that were treated as guidance. None of it shows on day one, and all of it shows in year three.
An open masonry fireplace in a 1920s house is an inefficient way to heat a room; much of the warmth leaves up the flue along with the air the room has already heated. An insert closes that system and vents through a properly sized liner. Gas units are different again — they install cleanly, and it is worth knowing before you choose one that gas service afterward carries no workmanship warranty, even though the installation itself does.
Installation crews cover both Massachusetts markets — Burlington and here — across the wider service area. The full local list is on the Wellesley page.

This is a choice rather than a repair, so the signs are about what the fireplace fails to do rather than what has broken.
The first one surprises people, and it is real. An open fireplace draws heated room air up the flue to feed the fire, so on a cold night in a draughty pre-war house it can cost more warmth than it produces. That is the specific problem an insert solves.

The best installations are boring. Measured right, vented right, tested before we leave — and then it just works, every winter, for years.
The flue is evaluated before an appliance is chosen, because the appliance has to suit the chimney rather than the other way round. Most installs are one to two days on site, and a permit is required for most liner, stove, and new fireplace work — filed with the Wellesley Building Department, with gas and plumbing permits issued only to licensed individuals through the town’s own inspector.
01
A $49 chimney inspection confirms the flue, crown, and structure can host the appliance — and the firebox is measured for exact insert fit. The fee credits toward the work.

02
Unit, liner or venting, subcontractor allowances, and timeline — one package price, fixed in writing before anything is ordered.

Wood inserts get a stainless steel liner run the full flue height; gas units get dedicated venting matched to the appliance. This is where efficiency is won or lost.

The insert is set, connected, and finished clean. On gas packages, licensed gas and electrical subcontractors work under our coordination — one crew responsible.

Every function tested before we leave: ignition, damper or valve, blower, shutoffs. You get the full walkthrough, the documentation, and a fireplace that's ready tonight.

Surround, mantel, tile, and finish work on a built-in gas fireplace. The appliance and its venting are in the package; the carpentry and tile around it are quoted separately.
Subcontractor cost above the allowance. Electrical and gas allowances are stated in the package. Where the actual cost runs higher, the difference is billed and you hear about it before the work happens, not on the invoice.
Customer-supplied appliances. We do not install units we did not source, because the workmanship warranty cannot stand behind an appliance of unknown origin.
