Gas Line Services: Why Professional Installation Matters
Gas line work is one of the few home improvement projects where cutting corners can have life-threatening consequences. Whether you’re adding a gas line for a new stove, extending service to an outdoor kitchen, or repairing an aging line, professional installation by a licensed technician is non-negotiable.
At MMDS (Mechanical Management & Design Solutions), our licensed plumbers handle all types of gas line installation, repair, and inspection for homeowners in Schaumburg, Evanston, and the greater Chicagoland area. Here’s what you need to know before starting any gas line project.
Common Gas Line Projects for Homeowners
New Gas Appliance Connections
Adding a new gas appliance — whether it’s a range, dryer, water heater, or fireplace — requires a dedicated gas line run from your main supply. Each appliance has specific BTU requirements that determine the pipe size and configuration needed.
Gas Line Extensions
Running gas to an outdoor kitchen, patio grill, fire pit, or a new addition requires extending your existing gas system. This involves calculating total BTU demand to ensure your gas meter and main supply line can handle the additional load.
Gas Line Repair and Replacement
Older homes in Schaumburg and Evanston may have aging galvanized steel gas pipes that are prone to corrosion and leaks. Replacing these with modern black iron or corrugated stainless steel tubing (CSST) improves safety and reliability.
Gas Leak Detection and Repair
If you smell gas (a rotten egg odor), hear hissing near a gas line, or see dead vegetation above a buried line, you may have a gas leak. Leave the area immediately and call 911 or Nicor Gas at 888-642-6748. Once the immediate danger is resolved, MMDS can repair the line and perform a pressure test to verify the system is safe.
Gas Line Installation Cost Breakdown
Gas line costs depend on the distance of the run, pipe material, accessibility, and local permit fees. Here are typical costs for Schaumburg and Evanston installations:

Permits and Code Requirements
Gas line work in Schaumburg and Evanston requires permits and inspections. Here’s what’s involved:
Village of Schaumburg
Schaumburg requires a plumbing/mechanical permit for all gas line installations and modifications. Work must be performed by a licensed contractor. Inspection is required before the line is placed in service.
City of Evanston
Evanston requires a gas piping permit through the Building & Inspection Services Division. All gas work must comply with the Illinois Plumbing Code and IFGC (International Fuel Gas Code). Inspections are mandatory.
MMDS handles all permit applications and coordinates inspections as part of your project — you don’t need to deal with the village or city directly.
Gas Line Safety: What Every Homeowner Should Know
Signs of a Gas Leak
- Smell: Natural gas is odorized with mercaptan (smells like rotten eggs). If you smell it, take it seriously.
- Sound: A hissing or whistling sound near a gas line or appliance.
- Sight: Dead or dying vegetation in a line above a buried gas pipe. Bubbles in standing water near a gas line. Dust or dirt blowing from a hole in the ground.
- Physical symptoms: Headaches, dizziness, nausea, or fatigue that improve when you leave the house.
What to Do if You Suspect a Gas Leak
- Do NOT turn on/off any electrical switches, lights, or appliances.
- Do NOT use your phone inside the house.
- Open doors and windows if safe to do so.
- Leave the building immediately.
- Call 911 and Nicor Gas (888-642-6748) from outside the building.
- Do not re-enter until cleared by the fire department or gas company.
Carbon Monoxide (CO) Protection
Any home with gas appliances should have carbon monoxide detectors on every level and near sleeping areas. CO is odorless and colorless — detectors are your only warning system. Illinois law requires CO detectors in all residences with fuel-burning appliances.
Gas Line Materials: What We Use and Why
Black Iron Pipe
The traditional standard for interior gas piping. Durable, reliable, and code-approved everywhere. Requires threaded connections and professional installation.
Corrugated Stainless Steel Tubing (CSST)
Flexible yellow tubing that’s faster to install and requires fewer fittings. Must be properly bonded to your home’s grounding system to protect against lightning strikes. CSST is ideal for retrofit installations where routing rigid pipe would be difficult.
Polyethylene (PE) Pipe
Used exclusively for buried exterior gas lines. Corrosion-resistant and long-lasting. Cannot be used indoors or above grade.
Frequently Asked Questions
Can I install a gas line myself?
No. Illinois law requires gas line work to be performed by a licensed plumber or gas fitter. Improper installation creates explosion, fire, and carbon monoxide risks. Additionally, DIY gas work won’t pass inspection, and your homeowner’s insurance may deny claims related to improperly installed gas lines.
How long does gas line installation take?
Most single-appliance gas line installations take 2–4 hours. Larger projects like whole-house repiping or outdoor extensions may take 1–2 days. MMDS provides a time estimate with every proposal.
Is it worth converting from electric to gas appliances?
For cooking and clothes drying, many homeowners prefer gas for performance and operating cost. A gas range provides instant heat control, and gas dryers typically dry clothes 25% faster than electric. However, the trend toward electrification (especially with heat pumps) means the answer depends on your long-term energy plans. MMDS can help you evaluate both options.
How do I know if my gas lines need replacement?
If your home was built before 1980 and still has original galvanized gas piping, it’s worth having a professional inspection. Signs of aging include corrosion on visible pipes, difficulty getting appliances to light, or a metallic smell near pipes. MMDS offers gas system inspections and pressure testing.
Do you handle gas line work for water heaters and furnaces?
Absolutely. Gas line connections are included as part of any furnace, water heater, or boiler installation by MMDS. We also repair or upgrade existing gas connections as needed.
