Comcast XFINITY → Re: [Connectivity] "not servicable" despite trunk line

What exactly do you think I'm doing?... I thought it was sort of clear that's exactly what I'm doing. But it seems ridiculous that any house more than a few hundred feet from the utility poles could be cut off anytime the cable company felt like it.

No they can't. That's why comcast goes through this process, right now they have told you "we are NOT legally obligated to serve your home" and "we will calculate the cost of putting a drop in" But once they return that bid, if you accept and return it with the proper payment and forms (ROW, etc.) they then ARE obligated to build, and maintain a drop FOREVER.
Most of the time when a cul-d-sac or other property is bypassed it is due to one of the specific "NOT SERVICABLE" exemptions in the Franchise or or state utility regulations. (usually RoW or setback issues)

Beyond a couple hundred feet the cable company HAS to install additional signal amplification equipment which needs power and access for regular maintenance. It's not just a "feeling" the cable company has, it's physics they have to obey.

Not everybody wants cable or the equipment on their property.

If it's a line passing through to feed OTHER customers, it's a totally different situation that involves utility easement permits that overrule individual landowner rights to a certain degree.

Not at all - you made it sound like you own and live in the house already.

I also thought you owned the house. When you dont own the house it opens up a new can of worms. You need to enter into a agreement of sale and make it contingent on being able to have cable installed to the house before it goes anywhere. I just started one this week that was 2000 feet from the road with just that scenario. We were able to cut it down to 1150 feet by securing a ROW from the neighbor at the price of a years free cable. We installed conduit thru the ROW and will finish the buildout after closing. It cut the price down pretty much and cant be completed until after closing. My main point is other factors come into play. the cable company i work for was able to guarantee a price once the ROW was secured and the conduit installed. So the potential buyer was able to just pay that part until closing takes place. Personnaly if cable was a priority of mine i would just move on to the next house.

I thought saying "a house I would like to move to" would indicate pretty well that I don't own it, but w/e.Wasn't an option, sellers wouldn't agree to contingency.

Anyway, I got an estimate of about $3k for the 1k foot run under ground. Relieved since I was preparing for much worse, but still a fortune when you shift back to the perspective of a normal view.

Who did you get that estimate off of? I hope it was comcast. You wouldnt be the first person that paid someone to run cable only to find out its unusable. 3 dollars a foot for cable to be run underground is way to cheap. Makes sense if it was actually comcast since they usually eat the first 3thousand dollars in expense.

Yes it was comcast.
