Merrillville grew up where I-65 meets US-30, and most of its homes were built in the decades since — split-levels, ranches and two-story houses, many with gas fireplaces or factory-built wood units rather than old masonry chimneys. That changes what usually goes wrong.

Gas fireplaces here tend to fail quietly: a pilot that won't stay lit, a burner that lights unevenly, glass that fogs up. Wood-burning units need the same annual sweep and inspection as any chimney, and their metal chases need a sound cover on top. We handle all of it, with photos and a flat price first.

What we do in Merrillville

  • Gas fireplace repair. Pilots, thermocouples, igniters, valves and blowers — free diagnostic visit.
  • Annual gas service. Burner and log cleaning, glass cleaning, burn test and CO check.
  • Factory-built fireplace sweeps. Wood units in newer Merrillville homes, swept and inspected for $249.
  • Chase cover and cap replacement. Keeps water out of metal chimneys and the framing around them.

FAQ

Merrillville questions

Is there a gas fireplace repair service near me in Merrillville?

Yes — we repair gas fireplaces throughout Merrillville and Lake County. The diagnostic visit is free if you go ahead. Common fixes: pilot cleaning $180–$220, thermocouple $195–$265, thermopile $220–$310, gas valve $320–$450.

My gas fireplace pilot light went out and won't relight — what's wrong?

Most often it's a dirty pilot assembly or a worn thermocouple or thermopile that can no longer hold the gas valve open. It's usually a same-visit repair. If you smell gas at any point, leave the house and call your gas utility first.

Do you sweep chimneys in Merrillville?

Yes. The sweep is $249 flat and includes a 21-point safety inspection and before-and-after photos, for wood-burning and gas flues.

How often does a gas fireplace need service?

Once a year. Gas burns cleaner than wood, but burners collect dust, pilots clog, and the vent still needs to be checked. An annual service with a burn test and carbon monoxide check keeps it safe.

What does a chimney inspection cost?

A Level 1 inspection is free with a written photo report. A Level 2 camera inspection, needed for home sales or suspected damage, is $199.

How soon can you come?

Most visits are scheduled within the same week, and problems like smoke in the house or a gas smell are prioritized — often the same day.

Will you leave soot in the house?

No. We cover the floor from the door to the fireplace, seal the opening and run a HEPA-filtered vacuum through the whole job.

Ready for a safer, cleaner chimney?

Same-week appointments, honest flat pricing, no scare tactics — and same-day emergency service when it can't wait. Licensed and insured.
