Review by in Selden, NY
Very professional, knowledgeable, honest, reliable and reasonably priced. Did not try to scam me into other services or products. Do not waste your time with any other company. I shopped around extensively. And by all means do not hire a fuel oil company. They will add their exorbitant commission (50%) and sub the work out to C2G anyway. I am completely satisfied with their service.

Looking to replace an inside fuel oil tank finding numerous companies either not rated highly or interested, my wife suggested "Home Advisor." Glad she did. We received a call from Chrissy of C2G immediately after hitting the send tab of the HA site C2G. The day wee received an info pack/contract in the mail. Deciding on C2G the work was scheduled, completed by two hard working men. Other than the newly installed material no one would have thought they were there. Quick, professional job. Happy with C2G .

Review by in Greenwich, CT
We returned home from a trip 2 days ago and found that an old oil tank in the basement was leaking. I found C2G on HomeAdvisor yesterday. The tank was gone this morning. They also did soil analysis at no extra charge and found no further issues. Chrissy from their customer service was awesome, the quoting process was highly professional and efficient, the price was reasonable and the guys did the job extremely well. We even received a call letting us know that they are running 15 minutes late due to traffic. We couldn't be happier. Thank you C2G!!!

Review by Patricia E. in West Islip, NY
Never again. I hired them to inform me if there was a tank underground and if not- what the gas line was. They came onsite and told me there is no tank and that the gas line might have been from an old tank, that it was not connected to anything therefore it could be easily removed. Come to find out they no nothing about gas lines and this one was active and was connected to my home! Waste of $1K.
Response by C2G Environmental Consultants, LLC: Dear Mrs. Patricia E. Ground Penetrating Radar (GPR) is a highly sophisticated and expensive piece of technology. It is however limited by the geology. We can identify the size and shape of tanks, utility lines or other structures. It cannot identify if lines are active. We are sorry for any part we may have played in not clearly conveying the limitations of the machine. We wish you well in the rest of your project and God Bless.

Review by in Middletown, NY
I hired C2G to put in a new outside oil tank and fill in my old in- ground tank with stone. They came and checked out the site and I was told that it could be installed outside where I wanted it. I decided to put landscape ties AROUND where the tank would be standing (upright) to make it more stable, as it was on a slope. When they came they said that it wouldn't fit where I was originally told, but they could set it ON TOP of the landscape ties. I said that it didn't seem stable that way, especially since the tank would be upright. They told me it would be fine. They also started working on filling the old tank. They cut hole about 20 inches in diameter and cut it at one end of the tank. I told them that the worker who inspected the site said that it should be about 5 feet long in order to get the stone fill to the other end of my 1,000 gal. tank. Again they assured me that they could spread it to the other end of the tank. After they completed the work I was still uneasy about where the tank sat. So I called the company that made the tank and told them about where the tank was sitting and asked if the warranty would be covered. They asked me to text a photo of the work. They then informed me that they would not honor the warranty where the tank was sitting. I called C2G and they did come back but wanted to put the tank in the same area without the landscape ties. I told them that I didn't feel comfortable with that and they agreed to put it in the basement. They didn't charge me for this but I had to keep the high end outdoor Roth tank which was about a thousand dollars more than a good indoor tank. About a month later a big sink hole formed where they filled the old inground tank. When I inspected it, I could see that they didn't even try to push the stone to the other end of the tank. I called and they did come back and cut a bigger hole ( but still not near the 5 ft. size I was first told was needed). This time I stayed around and made sure they pushed it toward the other end of the tank. End of story? NO! After the second filling of my new tank I got an oil leak in the pipes coming into the tank. I called but was told the warranty was up and would be charged $150 per hour for labor. After a lot of arguing they gave me a 3 mo. extended warranty for $145. They did come to supposedly fix the problem. End of story? NO! The next filling I had another leak (In a different pipe joint). I called and they agreed to come, without charge but said this would be the last time. At this time, I requested that one particular worker, who I didn't trust, not be sent. They said they wouldn't send him. Guess what, they sent the same guy! It's been about a year since I first contacted C2G but I wanted to make sure everything was complete and working right before rating them. I haven't received another oil fill since the last leak but didn't want to wait any longer to give a rating. For the most part they didn't give me a problem as far as coming back for each issue, except the one time that they charged me. This is the only reason I didn't give them a zero rating. VERY DISSAPOINTED! Tony P.
Response by C2G Environmental Consultants, LLC: Mr. P. [Consumer name withheld at their request]: We are so sorry for your disappointment. We stand behind all of our work and our employees. Please note that all of our work was approved and inspected by the local building department. I am not sure if we were the contributing factor to your issues; however, we are glad all are/were finally rectified. Best to you and your family, God Bless.

What is the screening process that Service Professionals go through in order to become members of the HomeAdvisor network?

  1. Verify Trade License
    HomeAdvisor checks to see if the business carries the appropriate state-level license.
  2. Verify Insurance
    As a part of our screening process, we encourage professionals to carry general liability insurance. We require coverage for hundreds of services.
  3. Verification of State Business Filings
    For business types that require a Secretary of State filing, we confirm that the business is in good standing in the state in which it is located.
  4. Criminal Records Search
    HomeAdvisor uses 3rd party data sources to conduct a criminal search for any relevant criminal activity associated with the owner/principal of the business.
  5. Sex Offender Search
    We confirm that the owner/principal is not listed on the official state Sex Offender web site in the state in which the owner/principal of the company is located.
  6. Bankruptcy Search
    We use 3rd party data sources to check the history of the principal/owner of the business for bankruptcy filings by or against them.
  7. Legal Search for Civil Judgments
    We use 3rd party data sources to check the principal/owner of the business for state level civil legal judgments entered against them.
  8. Liens Search
    We use 3rd party data sources to check the principal/owner of the business for liens placed against them.
  9. Identity Verification (SSN)
    HomeAdvisor verifies the social security number(s) of the owner/principal for identity check purposes. This check applies primarily to smaller business entities.
