Ok, so my garage is detatched and I'm looking to have the natural gas run out to it for heating. The meter on the house is on the corner nearest to the garage so its only about a 10 foot underground run.

I was quoted $2000 dollars just to run the gas line with me having to dig the trench and supply the sand for the trench...

This is by my wifes uncle, while I don't expect him to work for free this seems like alot of money to me??? maybe I'm off base....

Thoughts?

Total RIPOFF at $2,000 for ten feet, after you've dug the trench !!!

Look at prior GJ threads as this has been discussed many times. Use Google and search:
buried natural gas line site:garagejournal.com

You'll need the following:
a) yellow plastic polyethelene pipe (go with 1") that is 55 cents a foot
b) riser at each end that transitions the plastic to steel (same 1" size - - IPS which is Iron Pipe Size)
c) shutoff valve (black pipe steel) meant for outdoor use, as they have holes so you can lock in closed position
d) Stablock connectors on each riser that connect the yellow plastic pipe to the risers
e) chamfer tool to prepare ends of yellow pipe to properly seat in the Stablock connectors
f) also put tracer wire around plastic pipe in trench so it can be found later

I'm guessing your total parts cost will be $200 so your "uncle" is doing you no favors. :eyecrazy:

Find the nearest WinnNelson wholesale supply house and talk shop with the guy at the counter. You'll get the real story, and not hogwash your "uncle" has been feeding you! ;)

We have a local plumbing supplier that will make up and pressure test an entire gas line, including a shut off.
We just put in a 24 foot run for a BBQ at a friends house. We unrolled the new gas line, dropped it in the ditch and hooked up each end. A little soapy water on our connections and we were cooking with gas...literally!
I imagine other suppliers offer this service...

Have you called the gas company?
We just built a garage in our backyard which is down a side road. We live in the country. Our gas company extended the main a couple hundred feet down the side road and ran a run from the main to our garage, about 90ft. And put in a meter.

Didn't charge us a penny.

The cost may not be for just the materials but for the permits, special pressure gauge and knowledge of what needs to happen to get it approved and usable. One of my rentals just lost a gas line and I had to have it replaced. @$600 in parts and $1200 in labor only to be told "it failed" WTF!!! seems my plumber didn't know that if plastic goes in the ground you have to run tracer wire too. Rules were changed like 6 months ago.

a bit more digging and we're good to go.

That do that here in Wisconsin too. The gas company will run 100 feet (buried) from the street to the garage for free and they will install a gas meter for free. If it is over 100 feet then they do have a charge of $6.50 per foot. (in the case of the opening poster even if the gas company charged him the cost would only be $65.50 to run the line that 10 feet) The only thing is, you will get charged not quite $10 per month for the meter charge whether you use any gas or not.

Yeah, I'm in WI. I guess I should put that in my location. I'm in SE WI too.

Here in the expensive Northwest (Washington State), I just paid $1700 to have a gas line run from the meter to my shop.

I pre-dug the ditch, laid the sand, etc.

It was about a 60 foot run with a couple of fittings on the flex line and two vertical risers.

This price also included running the fitting through the wall of my shop, up 14 foot, in line shut off valve, and attaching to my heater with pressure check, etc.

It sure is nice to walk out to the shop and turn up the thermostat so I can work without a coat on. :rocker:

I had to go through the initial cost of tapping into the gas main and getting a meter installed because my property never had gas service installed yet.

This was very expensive at $2800!!

But again, very well worth it to be able to have my dream shop heated just the way I want it, anytime I want it. :thumbup:

We had natural gas going to the house, but I didn't want to tap into that gas line and then run a line to the garage. Too much concrete to deal with. So I contacted the gas company (W.E. Energies) and they sent out a very nice young lady to check out the situation. Then they came out with some heavy duty equipment and they ran an underground gas line from the street to the garage and installed a gas meter. Like I said, they will do 100 feet for free. Anything over 100 feet they charge $6.50 per foot which is pretty reasonable when compared with renting a digging machine, buying the pipe and installing it yourself.

I was quoted $200 to have a trench 70'.
plus

plus maybe $200 for a qualified person to install line?
total $600?
$400 with out a trench - you dig = save $200 - but in winter time, do you want to dig yourself?

When I built my garage, I buried 1-1/2 inch poly water pipe where the gas line was to go. It was right at about 100' of line. The contractor came in the fall and fished the gas line through the poly and did the heater installation.

Just curious, why didn't you just run the gas line?

My plumber came out and dug two trenches, 120 feet each. One for water, one for gas. He stubbed off both services inside the shop and buried the line when he was done. $1500 total.

I'm surprised you aren't allowed to do the work yourself. Just about everywhere allows the homeowner to do their own work, but you might still need permits of course.

It's not rocket science. We had to re-run our gas line from the meter to the house (opposite sides of the yard) because the old iron pipe literally rusted with holes in it. Replacing with the poly pipe was a piece of cake.

How do you know? He could be getting the deal of the year, he could be getting ripped off. No one can even begin to make the assessment without knowing all the facts.

Is he pulling a permit and how much are permit fees?
Permit fees vary widely. Some towns here would charge $50 for that permit. Others would charge $500 worth of permit and inspection fees.

What kind of inspections are required?
Most towns around here require the trench to be dug and the gas line installed with a pressure test attached. The pressure test has to sit for at least 24 hours. At that time the inspector will come meet the plumber (it has to be the plumber) to pass it.

How much work is it to cut into the existing gas header?
Sometimes this can be very easy and I can cut in a tee and valve in under an hour. Sometimes everything has to be reworked at it can be hours and hundreds of dollars in material.

Does the meter have to be upgraded to carry the additional load?
It's not an option. If your current meter will become to small to carry the load of every gas fixture attached to that meter running at the same time you will need to upgrade your meter to pass inspection. Now you run into additional work on the meter header and another trip out to meet someone from the gas company.

What is he doing at the garage?
I'm assuming permits are being pulled? The inspector is going to want to see the heater properly installed, connected and running before he signs off. Is he also bringing the gas line inside and connecting to or installing any heating equipment?


It's very easy to say $2000 for 10' is a rip off. It may well not be or maybe it is. Lets say worst case scenarion. He'd have to :
Day 1:
Come out and look at the job
Go to town hall to pull permits
Call the gas company for a meter upgrade
Day 2:
Go pick up material
Re-pipe the existing header for the new meter with the appropriate sized piping, supports and test *****. Temporarily re-install the old meter.
A little bit of digging because it never works out perfectly.
Run the line from the meter area (not tieing into the meter yet) to the garage and tie into the garage heater leaving a pressure test on the meter side.
Backfill most of the trench with tracer wire 2" on top of the pipe and buried gas line tape 12" above the pipe. One area, usually around the gas meter must remain open so the inspector can see the connections you used. Call for inspection.
Day 3:
Meet the inspector.
Tie the gas line into the header.
Complete back filling.
Day 4:
Meet the gas company for a meter upgrade.


Suddenly it's ten to twelve hours of his time over four days. Permit fees could be hundreds. Material could easily hit $400. Ever priced locking gas *****? Now that's here and that's worst case scenario. No one here knows your scenario. If he's not pulling permits and he's just tying into your header and bringing a gas line up outside the garage, he may well be ripping you off.

Two weeks ago I had our local utility prepare an underground gas line for my new garage. It's 1 1/8" plastic with the "whips" made up at both ends. Cost was $335. That's $200 plus $1/ft for 135'.

WPS just ran the gas line from down the road where the gas ended at my neighbors house about 100 feet, under the road, and 200+ feet to the side of my shed. Cost 800 dollars.

Gas line here has to be run by a licenced contractor.
I got all the underground utilities buried at the same time without having to wait for them.
Also, if the line ever gets knocked off by a snow plow or whatever, it can be pulled and repaired without further excavation.

Our gas company will install up to 100 feet of main and 100 feet of service for free. I had them put in a line and separate meter at my barn and it was just over 100 feet, so I had to pay $7.

Guys, my dad's friend is going to do it for 1300. Still seems steep but its 700 less than the uncle was..... Plus he can do it in the next couple days.

I guess this is the cost of living in Massachusetts....

I don't understand why it's even 1300 ? Though I don't know all the issues based on many yrs of this kind of work . I see it as a 1/2 day job , maybe full day but even then . For us where I live ( most of us ) it's a $ 800. Job at best.
The ditch is dug that's the worst part.
What don't we know ?

+1 Have you checked with your local utility? Mine did a lot more for free. They ran a main up my street (I was the only one to hook up to it), then under the street to my house, then up to the house and a meter. Cost? Zero. They love to expand their footprint and add customers.

I was amazed how much they did for free.

This is a private line on the customers side of the meter. You had a main line extension. The gas company owns that line and could tee off of it to feed other customers if they desired. I think maybe there is more than just laying a 10' gas line underground. Probably have to stub into the new building and run up a wall to connect a heater. Plumbing aint cheap.

That's part of the issue , the op never gave many details . So we are all guessing and plumbers aren't cheap but if I could get the amount the op said was quoted , I would be a very rich man.
I have had a few days making that kind of money but it was for a whole furnace or boiler install , lot more work than what was mentioned.

Holy cow wish we lived near each other I would have done it for half that and made a great profit. I just bought my materials. 65' of pipe, 2 risers, shut off valve $185. Now throw in the 10' of black pipe and a few fittings in the house that was $45. Then it was knocking a hole in the wall and digging the trench.

Plumber had to

-take a trip out to my town to pull permit
-go pick up his materials
-come install materials
-call inspector
-meet inspector for inspection
-have insurance
-have a license for gas fitting

Even if he made 8 or 900 I have no problem with it.

OP . . . glad you got a safe and permitted install. Painfully obvious now that $2,000 quote from uncle was outrageous, as fully licensed professional did it for $900 less.

Did the plumber do a leak test?? Also, you have tracer wire around the yellow plastic pipe so it can be located later??

For your benefit, draw yourself a "To-Scale" layout of where the gas line is buried so you'll always know where it's at . . . even before you ever have to call Dig Safe in the future for a locate. Makes it lot easier if 5 yrs from now you are considering planting a tree in that area. Post an extra copy of drawing on wall in garage, so that it will be there for next owner of property.

leak test was on it for a day and a half and the gage never moved. Has a tracer wire and a yellow warning tape above the pipe.

I paid close to $1000 to have trench dug, line supplied, connected, traced, tested. Seeded yard after it was done. Line was just shy of 50 feet. I took some pictures of the area, so that I know where the line is from now on. I was going to do trench myself, but digging that deep into clay was the decision maker.
