Gas Line Services in Arlington Heights, IL

We provide comprehensive gas line services for residential and commercial properties throughout Arlington Heights and Cook County:

Gas Leak Detection & Repair — Using electronic gas detectors and pressure testing equipment, we locate leaks in supply lines, connections, valves, and appliance hookups. We repair or replace the affected section and verify the entire system holds pressure before restoring service.

New Gas Line Installation — Running new gas lines for kitchen remodels (gas ranges, cooktops), laundry rooms (gas dryers), living areas (gas fireplaces, log sets), outdoor spaces (built-in grills, fire pits, patio heaters), and utility areas (generators, pool/spa heaters).

Gas Line Replacement & Repiping — Replacing corroded or undersized black iron gas piping with new black iron or CSST (Corrugated Stainless Steel Tubing) systems. Common in pre-1970s Arlington Heights homes where original gas lines have deteriorated.

Gas Appliance Hookups — Connecting gas ranges, cooktops, ovens, dryers, water heaters, furnaces, fireplaces, and outdoor appliances. We install proper shut-off valves, flexible connectors, and drip legs per code.

Gas Line Pressure Testing — Pressure testing new and existing gas systems to verify integrity. Required for all new installations and recommended after any repair work.

Gas Meter & Service Upgrades — Coordinating with Nicor Gas when your home needs a larger gas meter or upgraded service line to support additional appliances.

Understanding the type of gas piping in your home helps you make informed decisions about repairs vs. replacement:

Black Iron Pipe (Most Common) — The traditional standard for gas piping. Threaded black iron pipe is durable and has been used in Arlington Heights homes since the village was developed. Older installations (40+ years) may show thread corrosion, joint deterioration, or internal rust that restricts gas flow. We inspect and replace compromised sections while maintaining system integrity.

CSST — Corrugated Stainless Steel Tubing — A modern flexible gas piping system that's faster to install and requires fewer joints than rigid black iron. CSST is approved by Illinois code and widely used for new installations and remodels. Important: CSST must be properly bonded (grounded) to protect against lightning-induced damage. Many older CSST installations in Arlington Heights homes were installed before bonding requirements were updated — we inspect and bring these systems into compliance.

Copper Gas Pipe — Used in some regions but less common in the Chicagoland area. Where present, copper gas lines require specific flux and solder types (never use plumbing solder on gas lines).

Galvanized Steel — Occasionally found in very old installations. Galvanized pipe is NOT recommended for gas service due to internal flaking that can clog regulators and appliance orifices. If your home has galvanized gas lines, we recommend replacement.

Each gas appliance has specific requirements for pipe sizing, BTU delivery, shut-off valves, and connection methods:

Gas Range/Cooktop — Typically requires a ½" gas line delivering 40,000–75,000 BTU. We install an accessible shut-off valve behind the range and use an approved flexible connector for the final connection. For kitchen islands with a downdraft cooktop, we route the gas line through the floor.

Gas Dryer — Requires a ½" line delivering approximately 22,000 BTU. We install a shut-off valve within 6 feet of the appliance per code and use an approved flexible connector.

Gas Fireplace / Log Set — Requirements vary from 20,000 to 60,000+ BTU depending on the unit. Vented and ventless units have different installation requirements. We coordinate with your fireplace installer to ensure proper gas supply sizing and valve placement.

Outdoor Grill / Kitchen — Gas lines for outdoor appliances must use approved materials rated for exterior/underground use. We typically run a dedicated line from your meter through the foundation wall, trenching to the outdoor location. Underground lines require proper burial depth and sleeving per code.

Standby Generator — Whole-house generators typically require a ¾" to 1" gas line depending on generator capacity and distance from the meter. We coordinate with the generator installer and Nicor Gas for any service upgrades needed.

Pool/Spa Heater — Pool heaters are high-BTU appliances (200,000–400,000 BTU) that often require upsized gas lines. We calculate the total BTU load on your gas system to ensure adequate supply.

If you smell gas (the distinctive "rotten egg" mercaptan odor added to natural gas) in your Arlington Heights home, follow this protocol:

1. Do NOT operate any electrical switches — Don't turn lights on or off, don't plug or unplug anything, don't use your phone inside the house. Any spark can ignite gas.

2. Do NOT light any flames — No matches, lighters, candles, or cigarettes.

3. Open doors and windows if you can do so quickly and safely while exiting.

4. Evacuate everyone from the building immediately, including pets.

5. Call 911 and Nicor Gas (888-642-6748) from outside the building or from a neighbor's home. Nicor Gas provides 24/7 emergency response for gas leaks in Arlington Heights.

6. Call Plumbers 911 after the area is secured. We provide 24/7 emergency gas line repair service. Once Nicor Gas has confirmed the area is safe to work in, we locate and repair the leak, pressure test the system, and restore gas service to your home.

Signs of a gas leak beyond odor:

• Hissing or whistling sound near gas lines or appliances
• Dead or dying vegetation over an underground gas line
• Bubbles in standing water near a gas line
• Visible dust or dirt blowing from a hole in the ground
• A gas appliance flame that is yellow/orange instead of blue

Proper gas line sizing is critical for safe, efficient operation. An undersized gas line causes low pressure at the appliance, leading to poor performance, incomplete combustion, and potential carbon monoxide production.

We calculate gas line sizing based on:

Total BTU Load — We add up the BTU ratings of every gas appliance on the system to determine total demand.

Pipe Length — Longer runs require larger pipe diameters to maintain adequate pressure at the appliance.

Pipe Material — Black iron and CSST have different flow characteristics at the same diameter.

Available Pressure — Nicor Gas delivers natural gas at approximately 7" water column (WC) to Arlington Heights homes. The piping system must deliver at least 3.5" WC at each appliance.

A common situation: a homeowner adds a gas fireplace and outdoor grill to a home that already has a furnace, water heater, range, and dryer. The existing ¾" main may not have enough capacity. We calculate the new total BTU load and determine if the main needs to be upsized or if a dedicated branch line from the meter is the better solution.

All gas line installation and modification work in Arlington Heights requires a plumbing permit from the Village Building Department. This is not optional — it's Illinois state law.

Key code requirements:

• All gas piping must be pressure tested at 1.5 times working pressure (minimum 3 PSI) and hold for 10 minutes with no pressure drop before being placed in service
• Every gas appliance must have an accessible, individual shut-off valve
• CSST systems must be bonded (grounded) per manufacturer requirements and NFPA 54
• Drip legs (sediment traps) are required at each appliance connection
• Underground gas piping must be buried to proper depth and protected from corrosion
• Gas piping must maintain required clearances from electrical wiring and other utilities

We pull all required permits, schedule inspections, and ensure every installation passes on the first inspection. Our plumbers hold Illinois State plumbing licenses with the appropriate certifications for gas work.

Gas line work costs vary based on the scope, pipe material, distance, and complexity:

Gas Appliance Hookup (existing gas line in place) — $150–$400 for connection, shut-off valve, and flexible connector installation.

New Gas Line Run (range, dryer, or fireplace) — $500–$2,000 depending on distance from the existing gas main and accessibility.

Outdoor Gas Line (grill, fire pit, patio heater) — $800–$3,000 depending on distance, trenching requirements, and whether the line runs through the foundation.

Gas Line Leak Repair — $200–$800 depending on the location and extent of the leak. Emergency/after-hours service may include additional charges.

Whole-House Gas Repiping — $3,000–$8,000+ depending on the number of appliances, pipe material selected, and accessibility of existing piping.

Gas Meter/Service Upgrade (Nicor Gas coordination) — Our labor for manifold and piping modifications typically runs $500–$1,500. Nicor Gas handles the meter and service line upgrade at their cost.
