On Google it holds 4.9 stars from 222 ratings. A recent customer said Romano and Dan had the old tank out of a walk-down basement and the new tank in fast. A recent customer said the oil tank replacement in their basement took under 4 hours and the office handled the permit. A recent customer said they had two buried oil tanks removed and the pricing was fair. A recent customer whose tank was leaking said the online quote came in lower than other quotes, and that the company cleaned up the oil that had leaked. A 2026 customer with a Friday-night leak said C2G was the only company of four where a person answered the phone, and the team was onsite by 10:00 the next morning. A 2023 customer said Jose and Ross replaced the tank, piping and accessories in a basement with low headroom. A recent customer gave one star, saying they paid $2950 upfront for a temporary tank they could not use for 3 days. A recent customer said a site-review appointment never reached the person coming to the house, twice, though the workmanship was fine. **Strengths:** - Fast tank swaps — recent customers said replacements took a few hours - Permit handling — a recent customer said the office handled the permit **Concerns:** - An upfront emergency charge — a recent customer paid $2950 for an unusable temporary tank - Missed site visits — a recent customer said two appointments went uncommunicated ## Claims & citations Every claim below is backed by real evidence rows — uncited claims are dropped in code before publication. - Rated 4.9 stars from 222 Google ratings _(confidence: high)_ - [Google](https://www.google.com/maps/search/?api=1&query=C2G%20Environmental%20Consultants%2C%20LLC&query_place_id=ChIJOTdlAjvC54kR3NNLtGFpsFA) — “Google: 4.9★ from 222 ratings” - A recent customer said the company removed an old oil tank and installed a new one in a walk-down basement _(confidence: high)_ - [Google Reviews](https://www.google.com/maps/reviews/data=!4m8!14m7!1m6!2m5!1sCi9DQUlRQUNvZENodHljRjlvT2trelNFNXRXVFV0WVhSM1RURmZVa2xxVGxOM1NGRRAB!2m1!1s0x0:0x50b06961b44bd3dc!3m1!1s2@1:CAIQACodChtycF9oOkkzSE5tWTUtYXR3TTFfUklqTlN3SFE%7C%7C?hl=en-US) — “5★ C2G Did an amazing job on the removal and installation of a new oil tank in my walk down basement.

We were initially hesitant to use them as they are not located near us, however, the process was easy, follow up was great and all staff that came to our house were top notch. Prices were competitive and never felt We were being taken advantage of. Nice… - **5/5 · Google Reviews · ROBERT ROY · 2026-10-12**: C2G Did an amazing job on the removal and installation of a new oil tank in my walk down basement.

They were a pleasure to work with, and I have no problem recommending them. - **1/5 · Google Reviews · A J · 2026-10-05**: Terrible experience with C2G. They required $2950 upfront to have a temp tank delivered, connected, and started so we could get hot water, yet we couldn’t use the tank for 3 days. They called this an “emergency service” that they arranged with our oil company. The kicker is they didn’t even tell us … - **5/5 · Google Reviews · Bilal Nizami · 2026-09-25**: C2G made the entire process pretty painless and easy, they were in and out in a matter of a few hours in the morning (arriving promptly I might add) for a tank replacement. I was expecting the process to entail a lot more headache but it was a pleasant surprise. - **5/5 · Google Reviews · Mac B · 2026-09-19**: Did a super quick and easy job of an old oil tank replacement in our basement not even 4 hours start to finish, everyone at the office was awesome and walked me through the process and handled the permit as well. Easy work! - **5/5 · Google Reviews · Lauren Valentin · 2026-09-03**: C2G went above and beyond. They were exceptional to work with.

Techs showed up on time, nice as can be. Replaced tank, explained tank features, left paperwork and cleaned up like they were never there. Would recommend highly. - **5/5 · Google Reviews · K S · 2026-09-01**: Chrissy was patient and kind when I called in a panic. She was able to get Romano out quickly to place an emergency tank. Romano was very knowledgeable and discussed the tank options we had and had explained why one may be better over the other due to the space we had available. They came back out … - **5/5 · Google Reviews · Madeline Fitzgerald · 2026-08-30**: A pleasure to deal with.
