"Lesson learned. Always get an estimate. BEFORE the work is done. At least a digital copy. Arrangements for the project were made, with some one named Lynn, for the company to send someone to complete the work. We were quoted over the phone 4500-5000 which included a mold test. A sub contractor with an entirely different company (National Mold Company) was sent. When the contractor arrived, he stated that the job would be much more simpler than first thought. This led us to believe that the job would cost less, no. All said and done, they charged $5500. All said and done, it's almost like no work was done. The stains and the smell are still there. Only one actual board was taken upon the attic room. The ceiling in the bedroom was primed and painted but are still visible and have a funky smell. At this point I'm going to. Do what we should have done; Do the job ourselves. Just now with $5500 less dollars in our pockets. A detailed receipt was not given even though it was requested."

Mold Test Company NJ
Mold Test Company NJ
When you have mold, making the correct decisions right away is critical. Whether it is mold in your home, school, place of work, or apartment there are many factors to consider. Are you going to be involved in a mold lawsuit? Will you be seeking property damages? Is anyone sick from mold exposure? Will you be seeking medical damages? Will you need expert witnesses? If so, what kind? Do you just want to test to be sure your environment is safe? Do you need post mold remediation testing to ensure a good job was done? These and other factors are questions which need to be answered before any environmental testing starts. It is important to know what your goals are and why your testing. Different goals require different environmental tests, i.e. medical damages and property damages require different environmental tests to prove your case in court. Tests that a common, or inexperienced, mold inspector would not typically use or know to use.
"They did a prompt professional job. I received the report in about 7 days. Mold was found in the air due to high humidity in the air. All of this seemed OK but then I was forwarded to the Biocide company that tried to get me to buy a DIY mold remediation kit. There a time pressure to buy the kit for the best price at $2400. They said the nature of the mold would require a hazardous work fee from any remediation company that would cost from $12,000 - 18,000. This is when I started questioning the service I received. My pulmonologist also looked at the test results & said the mold levels did not seem too bad. Also, the humidity readings on my house thermostat did not read the high level that the report stated. So, I do not know if there was any value with the service & I am not sure if I would recommend them. The only way to really find out would be to call in another testing company but I did not want to spend another $660. So, I had the remediation work done for $1900 & was satisfied."

"Jim, Eileen & team were incredible! We had a biohazard (previous rodent infestation) that needed cleaning along with the clutter that had accumulated. These folks hit the ground running and were incredibly hard working and efficient and thorough. They were also really kind and responsive and practical (for example, there was something I wanted to save and they helped me be realistic - sometimes I saved it anyway, and sometimes I let it go, but it was really easy to make the decisions. This cleanout was worth every penny and I truly don't know what I would have done without Jim and team. Jim was also great beforehand in helping me understand what they would (and wouldn't do), how to prepare, etc. I have done a similar cleanout elsewhere, and Jim's prices are very competitive. I am so grateful!"

ERC Environmental Inc.
At ERC Environmental we make dealing with your old oil tank easy - our tank removal, replacement and soil clean-up services come at a single flat rate. No surprise fees or hidden charges; we make the process stress-free from beginning to end. Our services include everything from digging out your old tank to locating your new one, even ensuring your outdoor space is returned to its former glory. Ancient, leaking oil tanks pose a problem for homeowners, often when they come to sell. You might be concerned about the cost of oil tank removal and replacement because many contractors won't give you the final fee until the project is complete. That's where ERC Environmental is different. We quote you up front for the job, so you know exactly how much you'll have to shell out. It won't cost a single cent more. Contrary to popular belief it takes a matter of hours to remove and replace an oil tank – not days or weeks – and you won't be without heat or water during the process. ERC Environmental is a state certified, licensed, reputable and professional oil tank removal and cleanup company. Talk to us about your tank today.
"I had a good experience with the oil tank removal. However, they weren’t clear about charges. I agreed to hire them because in shopping for estimates they were the middle man. However, look at the estimate carefully. If any permits need to be pulled they put “permit”-TBD and charge $150 to obtain the permit. So when I received there estimate I thought that was the complete estimate and there would be no other charges. This was not true. I paid half up front and the other half was due when the job was complete. When the job was complete I had an addition charge of $400 for obtaining the permit and the permit itself. When I explained my situation and asked that they give some type of credit with the $150 they threatened to sue me and put a lien on my house. Do I think it would go that far “NO”. Attorneys are very expensive. However, I will not be referring them to anyone because of the sneaky manner in which they charge and also the threatening manner in which they ended the job. It’s not worth the headache though. If $400 is going to make such a difference I will pay it. Stay away charged are not clear. When they found out how much the permit would cost I believe they should have informed me as well as informed me that it would cost $150 to obtain the permit."
