Why Choose Obsidian for Gas Piping Installation

We've run thousands of feet of gas piping for furnaces, boilers, water heaters, and fireplaces across Des Moines and the metro area. We understand the building codes in Des Moines, Ankeny, Urbandale, and surrounding communities, and we know how to route lines efficiently and safely through homes of every age and style. From 1950s ranch homes to modern modular construction, we've installed gas systems that pass inspection and deliver reliable fuel supply.

As a veteran-owned company, we bring precision and accountability to every job. We follow all state and local codes — ensuring correct pipe sizing, proper support, right-angle fittings, and gas-tight connections. We pull permits on your behalf, coordinate with your city's building inspector, and ensure the final installation passes all inspections. You get a professionally documented installation with full certification that protects your home and gives you complete peace of mind.

We're based in Des Moines and serve the metro area daily. We can schedule your gas line installation at your convenience and usually complete it in a single visit. If you're coordinating with a furnace or boiler replacement, we synchronize the timing perfectly so both projects finish together. No waiting for separate contractors or back-to-back visits — we handle the full coordination.

A gas line that's undersized will starve your heating system of fuel and reduce output, leaving you cold. An oversized line wastes money and can create performance issues. We calculate the right pipe diameter based on your equipment's total BTU demand, the pipe run length, elevation, and the fuel load. Then we install it precisely to match that design. Every connection is protected with isolation shutoff valves for safety and future maintenance.

After installation, we pressure-test every connection using nitrogen and a manometer — professional-grade equipment, not just soap and water. We also perform live-gas smell tests before handing over the system to ensure absolute safety. You get a written certification of our work, which your utility company or inspector will want to see. Your system is documented and guaranteed.

Our Installation Process

How We Install Your Gas Piping

From initial design to final inspection, every step is handled with precision and code compliance. Here's what to expect when you choose Obsidian Heating and Cooling for your gas piping installation.

Design & Measurement

Before we buy a single fitting, we inspect your home thoroughly and plan the exact route. We measure the distance from the utility entry to every appliance, identify obstacles like framing, ducts, and electrical lines, and note elevation changes. We also inspect your home's foundation, walls, and crawl space to determine the best path — minimizing exposed runs, using interior framing where code allows, and protecting the line from damage. We'll discuss the options with you and show you how the line will be routed before we begin.

Secure Permits & Notify Utility

In most cases, gas line installation requires a permit from your local building department. We'll file it on your behalf, and the city will inspect our work when complete. We also notify your gas utility so they know work is happening and can advise on any special requirements for your meter or supply line.

Permit Process
Permit Application

Submit to Des Moines or your city.

Detailed Routing

Provide routing and pipe sizing to inspector.

Inspection Scheduling

Schedule final inspection with the city.

Utility Coordination

Coordinate with your gas utility before we begin.

Requirements Review

Confirm any specific requirements or restrictions.

Run the Gas Piping

Our technicians carefully route the gas line through your home using approved materials — black iron pipe, CSST (corrugated stainless steel tubing), or rigid copper, depending on your home's setup and local code requirements. We secure the line every 4–6 feet with proper strapping to prevent vibration and damage. The line is hung at the correct grade (slight downward slope toward the meter) so any condensation drains back and doesn't collect at low points.

Where the line penetrates walls or floors, we seal the opening to prevent pests and air leaks. If the line runs exposed in a high-traffic area, we protect it with a cover or run it along a wall where it won't be damaged.

Installation Details
Code-Approved Materials

Install gas pipe to all specifications and standards.

Proper Support

Secure with heavy-duty hangers every 4–6 feet.

Correct Grade

Maintain slope and pitch for condensation drainage.

Safety Shutoffs

Install isolation shutoff valves at each appliance.

Protection

Protect exposed pipe in high-traffic areas with covers.

Sealed Penetrations

Seal all wall and floor penetrations properly.

Clear Labeling

Tag all connections for future technicians.

Make Final Connections & Test

Once the main run is complete, we connect to your furnace, boiler, water heater, or other appliances. Each connection gets a shutoff valve for safety and maintenance. Then we perform a comprehensive pressure test using nitrogen and a manometer, check every joint and fitting, and inspect for leaks using gas detection solution (bubble test). Only after all tests pass do we introduce live gas.

Testing Process
Shutoff Valves

Install isolation shutoff valves at each appliance.

Pressure Test

Pressure-test entire system with nitrogen.

Leak Inspection

Check every fitting and connection for leaks.

Gas Detection

Perform final live-gas detection and inspection.

Test Documentation

Document all test results and certifications.

Final Inspection & Handoff

The building inspector comes to verify that the installation meets code — they'll check the routing, connections, supports, and our pressure test results. Once approved, you get a permit sign-off, and we hand over the system completely. We give you a thorough walkthrough: where your main shutoff valve is, how to turn off gas at the meter in an emergency, what normal operation looks like, and what to do if you smell gas (immediately exit, don't use electronics, call your utility from outside).

You receive copies of all permits, inspection records, and our certification of the work.

Final Deliverables
Inspector Coordination

Frequently Asked Questions About Gas Piping Installation

We install black iron pipe, CSST (corrugated stainless steel tubing), or rigid copper, depending on your home's setup and local code. Black iron is traditional and durable; CSST is flexible and faster to install in tight spaces; copper is used in some jurisdictions. We follow your city's code and recommend the best option for your situation.

In most cases, yes. Cities and counties require permits for new gas piping to ensure the work meets code. We pull the permits on your behalf, pay the fees, and schedule inspections. The final inspection ensures your installation is safe and compliant.

Simple installations — like running a single line from meter to furnace — can be done in a few hours. Larger jobs that serve multiple appliances or require routing through walls may take a full day. We'll give you an estimate during the design phase.

Black iron is traditional, affordable, and very durable but requires threading and special fittings. CSST is flexible, faster to install, and space-saving, but costs more and requires special clamps. Copper is used in some areas and offers good durability. Local code often determines which materials are allowed.

After installation, we pressure-test the system using nitrogen and a manometer (pressure gauge). This ensures the pipe is airtight before we introduce live gas. Once gas is flowing, we use a soap solution — bubble test — to visually inspect every fitting and connection. If bubbles appear, we tighten or reseal that fitting.

We identify the leak, turn off the gas, fix the connection, and retest. If the leak is minor — a slightly loose fitting — we tighten or add sealant. If it's a defective fitting, we replace it. We don't stop testing until every connection passes and the system is airtight.

Yes. Older homes sometimes have space-planning challenges — tight framing, obstacles, existing utilities in the way — but we've handled installations in homes from every era. We may route the line externally on the home's exterior, through the basement, or under the floor. We'll find the safest, most code-compliant path.

Your utility company may do this for us, or we may work with your meter's isolation valve to safely control the gas flow. We coordinate with your utility beforehand so the process is smooth and safe. You won't be without gas service longer than necessary.

That's a common situation. We'll run the piping from the meter to your furnace, boiler, or appliance, sizing the pipe to handle the distance and BTU demand. Long runs don't increase cost much — just sizing and routing complexity. We'll quote you based on the exact layout.

Cost depends on distance, pipe material, routing complexity, and the number of appliances served. Simple single-appliance runs are more affordable than multi-appliance systems with long distances. We provide a detailed estimate before work begins so you know exactly what to expect.

The principles are similar, but propane systems often use different pressure regulators and fittings. If you have or are planning propane service, let us know during the design phase. We'll ensure all materials and connections are approved for your fuel type.
