"*DO NOT UNDER ANY CIRCUMSTANCES TRUST THIS COMPANY.* They entered my house without permission and fraudulently billed me over $400 for an emergency after-hours service call that I NEVER REQUESTED. Reader, there was no emergency and they never even had the courtesy to call to check if there was or to request permission to ENTER MY HOME, at night, without my knowledge. This is absolute insanity - my house is in a quiet wooded area and the thought that I could have been there alone and men just showed up at my door at night, uninvited and unannounced, is frankly terrifying. I've been a customer for 10 years for my vacation home in Jamaica, but Cota & Cota has now completely betrayed my trust. Having stored my door lock code in their files after a prior (legitimate) service visit, they just let themselves in, did god knows what (again, THERE WAS NO EMERGENCY), and then sent me a $400+ bill. That is completely unacceptable, a grievous betrayal of trust and, by the way, illegal. Cota & Cota's excuse for why they did this isn't any better either - after being an auto-delivery propane customer for about 10 years, without any notice to me, Cota switched my account to COD, meaning I'd have to call them to request delivery. I had no idea, SINCE THEY DIDN'T INFORM ME OF THIS ILLEGAL CHANGE TO MY ACCOUNT (yes, that's illegal under VT law too), and then they didn't make a propane delivery to my house for 11 months. Well according to Cota, they just spontaneously realized one day that they hadn't made a delivery in a while and probably should have, so they decided that my tank must be empty, our heat must be off, and it was February so my pipes could freeze! They realized that would be 100% their fault, since they had illegally switched my account from auto-delivery to COD, but instead of calling to CHECK if there was a problem with the heat, they ran right over to my house at night, illegally entered my home and then billed me for an "emergency" after hours "call" that I NEVER REQUESTED OR AUTHORIZED. I wasn't there at the time (thank god), but I have a webcam in the house which shows a digital reading of the internal temperature in the house and could easily have let them know if there was a problem (there wasn't). Mind you, I only got this version of the story after about 6 calls to Cota to sort out the billing issue for the "emergency after-hours call". I was blatantly lied to by three different people before being transferred to Jason Terry, the manager, who then told me the "truth" (which I highly doubt is actually the truth). I won't even get into the very shady delivery of propane that they subsequently made, in which they had struck out the metered price on the delivery ticket and manually increased it by over 50 cents per gallon, but that certainly looks very suspicious to me too and we have reason to believe that the number of gallons billed were not actually delivered. Consider yourself warned, especially if you are an owner of a vacation home in their service area. We have to trust local service people when we can't be there, but Cota & Cota has proven that they do not deserve that trust and should be avoided."

Gas Leak Repair questions, answered by experts

Consider an annual inspection conducted by a local plumber to prevent dangerous and destructive leaks. If you recently moved into an older home or are concerned about the age of your gas lines, call an inspector for a closer look. You may also be required to call an inspector after your contractor installs a new line for an appliance.

It can cost anywhere from $200 to $5,000 to repair a gas line. The cost may vary depending on where the problem is located. For example, if there’s a small gas leak somewhere that’s easy to access, the cost could be on the lower side. On the other hand, repairing buried lines and lines in other hard-to-reach areas will be more expensive.

A local natural gas plumber, gas fitter, or gas line specialist should fix gas leaks. Installing gas lines and connections improperly can lead to dangerous gas leaks and explosions. Only a certified plumber or gas line specialist should run gas lines. This is not a job to try out DIY skills, so hire a professional gas plumber or gas line specialist immediately to find the cause of the leak and fix it quickly.  

In North America, pipe measurements are listed as the nominal pipe size (NPS). This measurement refers to the outside diameter. As an example, a 1/2-inch copper pipe has an outside diameter of 5/8 of an inch. If a hardware store lists a pipe as having a 2 NPS, it means that all the pipes with this measurement have a 2 ⅜-inch outside diameter, regardless of wall thickness and inside diameter.

Capping a gas line costs approximately $125. The final price varies from $75 and $150 depending on your contractor’s hourly rate. To completely remove a gas line and cap it at the base can cost up to $250. Most contractors will charge a flat fee instead of by the hour since capping is often part of a larger project.
