Pricing, before you commit

Start with the diagnostic price

A gas fault has to be found before it can be priced, because one symptom can have several causes. Our inspection pricing page shows the cost of the gas fireplace check for your Newton home.

GAS FIREPLACE REPAIR IN NEWTON, MA

Gas fireplace repair covers the parts that light, control and shut down the fire: pilot assemblies, thermocouples and thermopiles, spark ignitors, valves, control modules and remotes. The technician runs the unit, finds the fault and quotes the part and labor before anything is ordered. Labor on the repair carries our 1-year workmanship warranty, and parts carry the manufacturer's warranty.

Annual service is the other half of the job. The glass is cleaned, the burner and pilot are checked and cleaned, the logs or embers are reset and the venting is inspected, with the unit tested before and after. The gas fireplace safety check is priced on our inspection pricing page.

Newton has two broad kinds of gas fireplace. Many older houses had gas log sets fitted into their original masonry fireboxes, often decades ago. Newer additions and renovations tend to have sealed direct-vent units behind glass. The parts and the price differ, and the method is on our gas fireplace repair page.

The Work

The first cold night is when gas fireplaces get tested.

A gas fireplace that sat unused all summer often refuses to start on the first cold evening in October. Dust and spider webs in the pilot tube, a weak thermocouple or a dead remote battery are the usual reasons. Most of these are small parts and a single visit, which is why the fault is found on site rather than guessed at over the phone.

A gas smell is different. If you smell gas, leave the house and call your gas utility from outside before booking anything. When a unit is old and several parts are failing at once, the technician will say so, and a new installation can be priced next to the repair so you can compare.

We service gas fireplaces in Wellesley, Burlington and across Massachusetts. All Newton services are on the Newton page.

When to book

Signs a Newton gas fireplace needs service.

Gas faults are usually specific. Describe the symptom as precisely as you can when you book, because it often points straight to the part.

01

The pilot will not light, or goes out when you release the knob

02

The burner lights, then shuts off after a few minutes

03

The remote or wall switch has stopped working

04

Black soot on the glass or on the logs

05

Flames that are lower, lazier or less even than they used to be

06

The fireplace has not been serviced in over a year

‍

If you smell gas at any point, treat it as an emergency, not a repair. Get everyone out and call your gas utility from outside. Everything else on this list can wait for a scheduled visit.

"

Most gas fireplaces we're called out to aren't finished — they need a thermocouple, a sensor cleaned, or a pilot assembly. That's usually one visit, not a replacement unit.

The Brown Chimney Standard · Newton

Thirteen villages, four historic districts.

Four local historic districts
Auburndale, Chestnut Hill, Newtonville and Newton Upper Falls are local historic districts. Visible changes to a chimney there can need a Certificate of Appropriateness, so it is raised at the quote stage, before anything is scheduled.
Half the city predates 1940
About half of Newton's homes were built in 1939 or earlier, according to Census data. Clay flue tiles, soft lime mortar and slate roofs are what to expect on most streets.
1-year workmanship warranty
Labor on our repairs and installations is covered for a full year, in writing. Parts carry the manufacturer's warranty.
Price confirmed before we start
The price is confirmed with you before any work begins. Anything extra we find is shown to you with photos and needs your approval first.

Gas fireplace check · the ignition sequence

Your gas fireplace isn’t dead. One link in the chain is.

Every gas fireplace lights the same way: call for heat, spark, pilot, flame proved, valve opens, burner runs. When it fails, it fails at one step. Tell us what you are seeing, and we play the sequence, stop it where yours stops, and name the likely part with the price from our price book.

VENT GAS VALVE MODULE THERMOCOUPLE / FLAME SENSOR
  • 1Call for heat: switch, remote or thermostat
  • 2Spark ignitor fires at the pilot hood
  • 3Pilot flame lights and holds
  • 4Thermocouple proves the flame
  • 5Main gas valve opens
  • 6Burner runs, vent carries exhaust out
Sequence stops at step 4 of 6

What is it doing?

What kind of unit is it?

Last serviced

Roughly how old is the fireplace?

Most likely part

Thermocouple / flame sensor

The thermocouple sits in the pilot flame and makes the small current that tells the gas valve a flame is burning. When it weakens, the valve does what it is designed to do and shuts the gas off. It is one of the most common gas fireplace faults, and it is usually a one-visit repair.

  • Thermocouple / flame sensor$450

    The thermocouple is diagnosed, replaced with the correct part for your valve, tested, and the pilot re-lit.

    Most likely
  • Pilot assembly$450 – $650

    The pilot is diagnosed; the assembly is replaced where the orifice or hood cannot be saved, then tested and re-lit.

    Also possible
  • Gas valvePriced after diagnosis

    Valve output and response are tested before anything is replaced. A valve is never swapped on a symptom alone.

    Also possible
  • Most likely repair, priced per visit$450
  • If it turns out to be something else: diagnosis and repair visit, labor and small parts up to $50 included$350 – $450
  • Major parts (valves, control modules, pilot assemblies, remotes)Priced separately
  • Warranty1-year workmanship on repair labor · parts: manufacturer’s warranty
  • Final price confirmed with youBefore work begins

Worth knowing

A gas fireplace that will not light usually needs one part, not a new unit. When a repair starts to approach the cost of a new insert, we price both so you can decide.

A control module is ordered only after your model is confirmed. This is a guide, not a diagnosis: gas faults are confirmed by testing on site.

What to expect

What happens during a Newton gas fireplace visit.

The technician runs the unit first, so the fault is seen rather than described. Then come the diagnosis, a written quote for any part, the repair and a full operating test. Most visits are completed in one appointment, and the fault and the part fitted are written into the record.

01

Arrival & gas safety check

Before any panel comes off, the technician checks for gas odour, tests the connection, and confirms the appliance is safe to work on. If there is an active leak, the gas gets shut off and the utility called — that comes before any repair conversation.

02

Fault diagnosis

Pilot, thermocouple, ignitor, control module, valve, and venting are tested in sequence to find what has actually failed. A gas fireplace that won't stay lit has half a dozen possible causes, and guessing at parts is how homeowners end up paying twice.

03

Parts confirmed in writing

You get the failed component named, the part price, and the labour quoted before anything is ordered or fitted. The labour carries our 1-year workmanship warranty and the part carries the manufacturer's — you are told what's covered up front, not after the invoice.

04

Repair or replacement

The failed component is replaced with the correct part for your appliance — thermocouple, pilot assembly, spark ignitor, or control module. Where the unit is beyond economical repair, we say so and price the replacement instead of selling parts into a dying appliance.

05

Operational test & handover

Ignition, flame pattern, valve response, safety shutoff, and venting are all tested before we leave. You get shown how the system behaves when it is working properly, so the next fault is something you can describe on the phone.

For transparency

What gas fireplace repair does not include.

Major parts. Control modules, valves, pilot assemblies and remotes are quoted separately before anything is ordered.

Gas line work. Changes to the gas piping are made by a licensed gas fitter under a permit, not as part of a repair visit.

Chimney or venting repairs. If the problem turns out to be the flue rather than the appliance, that is quoted as masonry or liner work.

FAQs

Gas fireplace questions from Newton homeowners

1 icon

Our gas fireplace worked last spring but won't light now. What happened?

Usually something small. Over the summer, dust or insects can block the pilot, and a thermocouple near the end of its life may no longer hold the gas valve open. The technician tests each part in turn and quotes the one that has failed.
Faq Number

The pilot lights but goes out as soon as I let go of the knob. Why?

That is the classic sign of a weak thermocouple or thermopile, the safety part that keeps the gas valve open once it senses the pilot flame. It is a common replacement and usually a single-visit fix.
3 icon

We have a gas log set in an old masonry fireplace. Is that serviced differently?

Yes. An open log set has an accessible pilot and fewer parts, so servicing is usually simpler. The masonry chimney above it still needs its own check, because the exhaust goes up that flue.
4 icon

Is the repair covered by a warranty?

Labor on our gas fireplace repairs carries a 1-year workmanship warranty. Replacement parts carry the manufacturer's warranty.
5 icon

When does replacing the unit make more sense?

When several parts are failing at once, or the unit is old enough that parts are hard to find. The technician will tell you if that is the case, and you can compare the repair with a new installation.
