Licensed gas-line pros for fireplaces, log lighters, and wood-to-gas conversions across Chicagoland

A gas fireplace should be the easiest warm thing in your home — flip a switch, and the room glows. Getting there safely is the part that takes a licensed hand: the fuel line behind that cozy flame has to be sized right, pressure-tested, and tied into Peoples Gas or Nicor service correctly. Midwest Gas Pipe Repair installs new fireplace lines, repairs leaks, converts wood-burning fireboxes to gas, and sets up gas log lighters — all to Chicago and Illinois code.

New gas fireplace line installs — vented, vent-free, direct-vent

Every gas fireplace, no matter the style, needs one thing done right before the first flame: a properly sized fuel line running from your meter to the firebox. Vented and direct-vent units (the kind with a sealed glass front that pulls combustion air from outside) and vent-free models all draw different amounts of gas, measured in BTU. Undersize the pipe and the flame starves; oversize the run and you've spent money you didn't need to. Our licensed techs measure the appliance's BTU demand, calculate the right pipe diameter for the distance involved, and run new black iron or flexible CSST (corrugated stainless steel tubing) to the hearth.

Where the line meets the fireplace, we install a shutoff valve, a sediment trap (a small drip leg that catches debris before it reaches the burner), and a code-compliant flex connector. This is the same careful approach we bring to any whole-home gas line installation — fireplaces just happen to live in finished, visible rooms, so neatness matters.

Wood-to-gas fireplace conversions (chasing a new line through an existing chimney)

Plenty of Chicago homes have a beautiful brick fireplace that nobody uses because hauling wood and cleaning ash got old years ago. Converting it to gas brings that hearth back to life with the flip of a switch. The trickiest part isn't the burner — it's getting fuel to it. There's rarely a gas line near an old wood-burning firebox, so we chase a new line to the hearth, often routing up through a basement, behind baseboards, or alongside the existing chimney chase.

We map the cleanest path first, coordinate any dig work with JULIE (call 811 before digging in Illinois), and keep openings in your walls as small as possible. Once the line lands, we set the gas log set or insert you've chosen, fit the connector and shutoff, and verify everything holds. Homeowners in Oak Park and Evanston love this upgrade for older two-flats and bungalows where a real wood fire was never practical anyway.

Gas log lighter installation (a separate, code-distinct service)

A gas log lighter is not the same as a gas fireplace, and it matters that you know the difference. A log lighter is a simple gas pipe with burner holes that sits under your real wood logs — you turn on the gas, light it, get the wood burning, then shut the gas off. You still burn wood; the gas just does the work of kindling. A gas fireplace, by contrast, runs gas the whole time the flame is lit.

Because a log lighter is used briefly and then shut off, code treats it as its own fixture with its own valve and clearances. We install a dedicated shutoff (usually a key valve mounted in the firewall just outside the firebox), run properly sized pipe to the lighter bar, and confirm there are no leaks before you ever strike a match. It's a modest job for a licensed crew, and it's one of the most satisfying small upgrades for anyone who still loves a real wood fire but hates fighting with newspaper and kindling.

Common gas fireplace leak symptoms and repair

If you smell gas — that rotten-egg odor comes from mercaptan, a scent added to naturally odorless natural gas — treat it as an emergency. Don't flip switches, don't hunt for the source. Leave the house and call 911 or your utility (Peoples Gas in the city, Nicor in the suburbs) first. Once the area is safe, we handle the private-side repair on your fireplace line.

Subtler signs of a fireplace gas problem include a flame that won't stay lit, a faint smell only when the unit runs, hissing near the valve, or a pilot that keeps going out. These often trace back to a worn flex connector, a loose fitting, a failing valve, or a cracked sediment trap. Our techs pinpoint the source with professional gas leak detection equipment rather than guesswork, replace the failed component, and then prove the repair held. Repairs from $199.

Permits, masonry coordination, and Chicago bungalow specifics

Gas fireplace work usually requires a permit, and the rules vary by jurisdiction — the City of Chicago, Cook County, and suburban authorities in DuPage, Lake, and Will counties each have their own process. We pull the permits and schedule inspections so the work is on record and done right. Once the line is in, we perform gas pressure testing to confirm the system holds before it's signed off.

Chicago's classic brick bungalows bring their own quirks. The firebox sits in solid masonry, so reaching it with a new line often means coordinating with a mason to core a clean hole and patch it afterward. We also handle bonding — electrically grounding metal gas piping, which is required for CSST so a nearby lightning strike can't arc to the line. We've done this work in Arlington Heights, Glenview, and across the bungalow belt, and we leave the masonry as tidy as we found it.

Cost ranges and what affects them

Honest pricing on a fireplace gas project depends on your home, so we quote in ranges rather than pretending one number fits all. The biggest factors are how far the new line has to travel from the meter, whether we're running through finished walls or open basement joists, the BTU demand of your chosen appliance, and whether masonry coring or wall patching is involved. A short run to an unfinished basement hearth sits at the lower end; chasing a line two floors up through finished plaster sits higher.

Permit fees, the type of pipe (CSST flexes around obstacles faster; black iron is sometimes required for exposed runs), and any related gas appliance hookups you bundle in all move the figure too. Repairs start from $199, while full conversions are a larger project. We'll walk the job, explain every line item, and never start work you didn't approve.

Seasonal scheduling (book Aug–Oct before peak)

Here's the open secret of the heating trade: everybody remembers their fireplace the first cold week of November, and the phones light up all at once. If you want your gas fireplace, conversion, or log lighter ready before the first real chill, the sweet spot to book is late summer through early fall — roughly August to October. Lead times are shorter, scheduling is flexible, and you're not competing with the whole Chicago metro for the same appointment slots.

That said, we never want safety to wait on a calendar. If you smell gas or your fireplace is acting up mid-winter, call us right away — we run 24/7 emergency dispatch with licensed pros across Chicago and suburbs like Schaumburg, Hinsdale, Joliet, and Bolingbrook, typically on-site within 30 to 60 minutes. Planning ahead saves you the wait; emergencies get you to the front of the line either way. Call (708) 381-2959 whenever you're ready.

Common Questions

Gas Fireplace Installation FAQs

In most cases, yes. Gas fireplace and conversion work generally requires a permit, and the process differs between the City of Chicago, Cook County, and suburban authorities in DuPage, Lake, and Will counties. We pull the permits and arrange inspections as part of the job, so the work is properly documented and signed off.
A gas fireplace burns gas the entire time the flame is on. A gas log lighter is a gas pipe under real wood logs that you turn on only to get the wood going, then shut off — you still burn wood. Code treats them differently, so each gets its own valve and clearances when we install it.
Yes. We chase a new, properly sized gas line to your existing firebox — often up through a basement or alongside the chimney chase — then install the log set or insert you choose with a shutoff and connector. It's a popular upgrade in older Oak Park and Evanston homes where a wood fire was never very practical.
Treat it as an emergency. That rotten-egg smell is mercaptan added to natural gas. Don't flip any switches — leave the house and call 911 or your utility first (Peoples Gas in the city, Nicor in the suburbs). Once the area is confirmed safe, call us at (708) 381-2959 and we'll handle the repair on your fireplace line.
It depends on line distance, whether we route through finished walls or open joists, your appliance's BTU demand, and any masonry work involved. Repairs start from $199, and full conversions are a larger project. We quote in ranges and itemize everything before starting. Get a written quote — every home is different.
Late summer through early fall — roughly August to October — is ideal. You get shorter lead times and flexible scheduling before the November rush when everyone remembers their fireplace at once. Emergencies, of course, are handled 24/7 any time of year across Chicago and the suburbs.
