Mark Underground Cable

I need the underground cable marked for my landscaper who will be doing some digging and edging around the house.

Hi there! Great question, and we’re glad you checked before any digging, that’s always the safest move.

 

For marking underground lines, you’ll want to contact 811 (Call Before You Dig). That’s a free nationwide service that notifies all utility providers, including Xfinity, to come out and mark their lines on your property.

 

You can either call 811 or submit a request online at Call 811. Once the request is submitted, technicians will come out and mark the lines, usually within a few business days.

 

We definitely recommend doing this before any digging or landscaping to avoid damage and keep everyone safe. Let us know if you have any questions along the way!

The concern is not "accessibility / disability" help related............ Topic moved here to the proper help section.

I called 811 to have my line marked. I got an email from Comcast’s saying there are no lines 

we know there are lines and need them marked. Who do I call?

Greetings @user_hvzt8t, and thanks for posting your question to the Xfinity forums, I hope this message finds you well. It is possible that there are lines that are buried in your yard, but if you called 811 and were told that there are no Comcast lines, then it is possible that there are some from another provider.

I have the same problem.  I have Xfinity/ Comcast cable and it was installed by Xfinity, but, I got the same email from Xfinity saying there was no cable when I called 811.  


Since the question wasn’t answered earlier, I am asking it again.

user_0331b7 If the locate request was incorrect, and you know there is an active Xfinity line serving the property, I would recommend contacting 811 again and requesting clarification on the locate results. You may also want to open a new locate request and specifically note that you have active Xfinity/Comcast service installed.

I am getting irrigation installed at my home and submitted a request with 811 and comcast to locate buried lines. Comcast promptly closed the case "No conflict" we know for fac that there are buried lines on the property.  I filed a second notice with 811 and called comcast directly.  Comcast sent out a technician who showed up at my home ready to install and setup my new service??? This is ridiculous. 


I work from home and cant be without internet should the irrigation contractor cut a line on accident because comcast didn't mark them.

I too had the same issue.  Within an hour of my 811 request, I got a "No Conflict" email.  I know that the new underground downspout drain line will cross my internet cable.  The email said to contact Florida's contractor "ITG Location Services at [Edited: "Non-Comcast Phone Number"].  I couldn't understand the customer service agent because of his out of country language accent.  He did say 811 requests get an automated response "no conflict".  He continued by saying he would pass my concern off to his supervisor.  This is absolutely the most frustrating experience and a total failure of customer service.

I have the same issue - I have xfinity in my house and I know the line is there. The locator in our area - On The Spot. They claim it is not in their contract to mark the lines from the pedestal to the customers house, that’s considered a private locate. That is total [Edited: “Inappropriate Language”] - ATT and metronet get marked- but that’s only because they use a different locate service…..might be time to switch. I have spent hours trying to get the line located. I have been informed by JULIE that it is well documented and that if the line is cut it won’t be my fault and that the claim it’s not part of On The Spot contract is incorrect. If Xfinity really didn’t include it in their contract with the locate company than Xfinity is extremely cheap for what they make customers pay!

Thank you for sharing your experience @user_vi4x96 on our Xfinity Community forums.

I can certainly understand how frustrating it would be to spend hours trying to get clarity on the location of your service line, especially when you've received conflicting information from different parties. We appreciate you taking the time to provide this feedback and explain the challenges you've encountered.

In most areas the property owner or excavator is solely responsible for locating and hiring a private company to mark private utilities, because free public "811" one-call services only mark publicly owned infrastructure up to the utility meter or point of connection (in some cases outside the property line.) 

To better understand the situation, can you let us know what type of work you are planning to have completed on your property? For example, are you preparing for landscaping, fencing, excavation, construction, or another project? Any additional details about the planned work may help provide more context regarding the locate request and the concerns you've raised.

We appreciate your patience and look forward to learning more about your project.

“Cliff” - you clearly have no clue what you’re talking about. 811 is to mark all utilities up to the point of connection to the house. Those are still publicly owned lines that are actually to be located within the easements of the homeowners property. Which might  add that Xfinity is lazy and cheap that they decide to cut clear across the yard not with in the easement. As I mentioned in my post ATT, metro net and ComEd lines were all marked from the pedestal to the point of entry into my house. That is because those lines are not owned by me the homeowner.

your question of asking what work I will be doing has not relevance- any dig work even if only 1” dig requires a call to Julie to have the lines marked. The only thing Julie will not mark is if I ran a private line with in my property - example a power line to my shed or irrigation power.

The best part is your line is to be buried 12-18” deep - 9 out of 10 times it is 4” deep and gets cut when some one digs and than you want to charge them to replace it. 
I did my dig with out the line marked - I know where it is from digging in my yard previously- I didn’t hit it and guess to my surprise it was only buried 5” in the ground - what a shocker - not.

At the end of the day Xfinity needs to clean up their act. Bury the lines correctly and stop [Edited: "Language"] the consumer. They came out to my house telling me they would mark my lines and got here and said they had to send a different Xfinity employee- no follow up no reschedule date….its a shame.
