If you just want to get a report and no explanation or implications of the report, then I suggest you call Same Day mold testing because that's all you're going to get--a one page report.  NO explanation or follow up about the findings of the report.  However, if you want someone who is VERY knowledgeable in the area of molds and takes the time to explain to you about the process, then you want to call Chuck from One Source.  I wished I had called him the first time around, that way I would have had my mold issue resolved.  He is not only knowledgeable but seems very concerned for my well being.  I called him in the morning and he made his way over to my house later in the evening, going completely out of his way just to give me an inspection.  At the house, he took the time to explain the issue and was very patient with all my questions.  He not only explained everything in great detail but he wanted me to walk away understanding the entire process ie. mold remediation, testing, and insurance claims.   Don't let the purportedly HIGH reviews from the other mold testing facilities fool you, especially one day mold testing.  All they want is your money.  They don't care if you pass the mold test or not. Chuck wants you to pass the mold test and will do what it takes.  He's unlike anyone I've encountered in this kind of profession.  I can't say enough about him.  Please give him a call, you'll be glad you did. Your peace of mind will thank you.

Chuck was very professional and spent a great deal of time explaining the results to me in a way that I could easily comprehend.  From the beginning of my interactions with Chuck, it was clear that he was committed to thoroughly resolving my issue as fast and cost effective as possible.  During the whole process, he was always transparent and provided realistic suggestions.  I would definitely recommend Chuck to anyone that is dealing with a water/mold issue.

I have worked with Chuck and team on a couple of occasions.  The latest call was to check the content of building materials that were disturbed during some home updates. They came out, took samples, and provided results the next day.  They have always been great and work to get services completed as quickly as possible, which is really important when you don't know what you are dealing with.  They respond to issues faster than most companies return your initial call.  I'd recommend them to anyone looking to get their home tested.  And should the need arise again, I would certainly call on them.

The deal was beyond disappointing.  The representative spent a great deal of time explaining the 'deal' was deceptive in that you had to read the 'small print' to realize that this inspection didn't include any testing.  Test would be necessary of assess the hazzard level and each room would require multiple tests costing from $75 to $125 each.  We focused on one wall in one room and he took a tape sample of the mold on the wall.  I paid the additional $75 for the test and did receive a 'report' with some information information about the mold.

"Hello, are you sure this experience was our company, One Source Group. This does not sound familiar, this inspection nor property and certainly is not our approach; we are exceptionally forth coming in our pricing even prior to our arrival. Our services are disclosed we have a work authorization, we report both our inspection findings and laboratory analysis. I would appreciate your looking back at your report and determine if this was from One Source Group. Thank you...."

Chuck at One Source Group was very responsive.  He was able to send someone to take samples of the ceiling on the day after I first called him.  The person checked the condition of the ceilings throughout the house and looked to see that they all appeared to have had the acoustic coating blown on at the same time.  He took 3 samples from 3 different places for submission to the testing lab.  Chuck told me that they usually get results within 48 hours, and he did have the results for me by then.  He called and told me that asbestos had been confirmed, then sent me the testing report for my records.
The only reason I rated One Source as a B rather than an A in professionalism is that the representative who came to take the samples reeked of stale cigarette smoke.  He was a nice guy, but I was glad it was a warm day so I could leave the doors and windows open to minimize the smoke smell that he carried in.
I was very satisfied with the quality and promptness of the service.
Response from One Source Group LLC
"Thank you for bringing this to our attention as to the cigarette smoke smell. I agree this is not a pleasant experience and I apologize on behalf of this person. We appreciate all feed-back and try diligently to make every customers experience and pleasant one. Thank you,"

We contacted Chuck on 10/17/2013 for an estimate and he was over to the house in escrow on 10/19/13 to look over the home's water damage and take samples for possible mold.  He arrived 30mins late, but we were not in a rush.  We were thankful that he could come out at all on such short notice.
The negotiations to the house fell through on 10/20/13 and Chuck was able stop the mold analysis request before they got sent out, refunding us $135.
What we appreciated most about Chuck was his integrity and helpfulness during a particularly stressful time as, thank you, Chuck!  If we needed another mold inspection, we would definitely work with Chuck again.

I recently needed the services of a company that could provide me with answers as to what the stains and discoloration on my garage floor were; to identify whether they were leached salts, mold, or something else.  I had just joined Angie's List, and decided to look up a firm who dealt in that area to see if they could help me.  I chose the One Source Group, and am very glad that I did.  The gentleman who answered the phone, Chuck, listened carefully to my problem, and was very helpful in explaining possible options open to me to see what the stains were, an opinion as to what he felt might be possible sources of the stains, and the price.  He also offered a senior discount, which was very helpful.  This business is clear that they do not do repair work, but sample collection, quantification, identification, and reporting, and this is exactly what I wanted. 
We set up that same day an appointment for the following morning.  An associate, Renee, came to the house right on time at 8:00 A.M., and was very professional and friendly as he collected the necessary air and material samples, which he then hand-delivered to a testing laboratory.  Chuck called again in follow-up the next day with the results (with a written report to follow) and explained them.  Knowing now what I am dealing with, I can go ahead and fix the problem that is causing the stains.  Chuck also said to call him any time if I needed further assistance, or if I had any other questions.  Both Chuck and Renee were very knowledgeable, and spent time explaining things to me; they made the experience go extremely smooth and fast.  I would certainly highly recommend them to others who need this type of work done.

One source representative visited my house  on 20th Jul for visual inspection. One source representative collected samples and took
pictures from my duct without my knowledge and written permission and they sent me an invoice of $410 for testing service and authorization letter to collect the sample after collecting samples without my written permission. When i refuse to pay the invoice so Mr. Chuck threatened me to put lean on my property and file a fake complaint with city, so i paid the invoice in full. I believe that One Source Group violated my privacy and collected samples without written permission, so they should refund my payment and
destroy the samples and they should stop unfair business practices.
Response from One Source Group LLC
"Our services of providing environmental inspection investigations take in to consideration a myriad of factors. Our clients potential exposure to toxic substances is a paramount concern and is truly the cornerstone of why we provide these services. When a client calls us we are walking into a new environment that we know nothing about and our dialogue with our client helps us to understand their concerns. We diligently try to understand what is happening in a property and with this science requires sampling, study and recommendations to protect the occupant and the property. When One Source Group is retained for our services we pride ourselves in addressing your concerns and we want a respectful working relationship with our customers. However, there are times when some ask for our services and have a large misconception or another agenda. In this inspection we were specifically asked to perform an inspection to include sampling for asbestos. Upon completion of the report we asked for payment of services. The customer decided to re-negotiate the cost of our services and wanted that we fold our cost in to the demolition of his HVAC duct work. As we mentioned to this client before we are a third party inspection company only and we do not provide demolition services since this would be a conflict of interest. We tried to explain to the customer that their matter was serious that their property was contaminated due to activities that damaged their ducting but once the customer learned that we do not provide demolition services he stated he did not want the report and would not pay. Unfortunately we were unable to educate this client and they do not have a working knowledge of regulated substances in California. Asbestos is a regulated substance known to the State of California to cause cancer and this matter, this environment, unfortunately was contaminated and is exposing the occupants; this is a serious legal matter and requires your attention. We hope that this client understand that to ask for services you are required to pay for said services and to broker a deal after the fact to save monies is an improper tactic especially when it comes to a persons health. We ask you to consider your exposure in this situation and sincerely suggest that you should take necessary actions to protect all occupant health in this property as soon as possible."

Even before they came to test, Chuck spent quite a while on the phone with me personally just answering questions and giving me an idea of the process. He was very honest about what to expect and the pricing. They were very quick in responding to my call. They were able to schedule a visit the very next day, on the weekend.  The visit went exactly as described by very professional servicemen.  Not only were they well informed, but also recommended that I call the homeowners insurance as a claim.  They were very quick about the results and Chuck even called me personally with the results and some recommendations.  He even was very conscientious to save us some money by cancelling some testing at the lab that wasn't needed because of the positive result. I would highly recommend them to anyone.

I am frustrated that there was no written final review of the total number of samples or  total costs before proceeding and as a result I ended up paying several times more then I expected.
Response from One Source Group LLC
"Hello (member name removed), as we brought to your attention in our email of the analysis for asbestos; asbestos sampling that we took from your home were 3 total samples not 12 the amount of lead sampling performed was 6 by your direction and not 9. The 12 total analysis is due to the laboratories "layering" of the samples that we have no control of and that is simply dictated due to the regulation of the examination see; EPA PCM 600/R-93/116 methodology for examination for building materials that may contain asbestos. The laboratory that we use is an accredited laboratory by NIST, National Institute of Standards and Technologies, which accredits asbestos laboratories by what is called NVLAP, National Voluntary Laboratories Accreditation Program. The laboratory, due to their accreditations will examine all samples thoroughly to ensure that the analysis is correct. When considering budget and time constraints, knowledge and ultimately safety, we at One Source Group will act in a professional and appropriate manner to provide you with accurate information. Our goal is to protect your health first and foremost and the difference in price due to the additionally analyzed samples was $180.00. We apologize if this caused you frustration but again our interest is your health and we will not sacrifice the quality of our work nor will we diminish our attention to the project we have been intrusted to perform. If you like we are more than happy to refund you the $180.00 due to our belief in serving not only our customers needs of understanding their structure but to also ensure that our customers are educated, informed and protected. Thank you, Chuck Moore"

I spoke with Chuck on the phone who gave me quotes for lead, asbestos, mold testing. I thought he would be performing the testing, instead  two guys from AAA arrived. That was fine that someone else performed the testing. I just didn't know until we got to our escrow property. I think it should have been mentioned in the phone call. Also I wish I would have known earlier on that the results are not released until you pay. I was waiting to get the results first and then pay but then I found out that you pay first then get the results. The way it worked out, I didn't get the results until a day 1/2 later. Just know to pay first in order to get your results. Overall we were satisfied with the inspection. Chuck was accommodating when I had to cancel then re-schedule the appointment.
Response from One Source Group LLC
"Member, we are happy that you were pleased with our services. I would enjoy being able to be at every inspection but in order for us to serve as many customers as we can we have to have employs. The technicians in your property are employs of One Source Group. What you saw was a ID badge for an on going commercial project where in we are the subcontractor to another company and I apologize if this confused you. One of our goals is to provide quick responses to our customers needs. We are constantly reminded that in today's business world transactions happen quickly. In order for us to maintain a timely response to your needs and a competitive edge we simply can not finance any project. We've made payment arrangements as easy as we possibly can by not only being a "Green" operation in that we handle all payments and documents electronically but we've given opportunities to pay via Paypal on our website as well. You may want to consider that many service providers require payment at time of service simply, in order for us to extend a low cost of service to our customer we require immediate payment. Thank you for your patronage it was our pleasure in servicing your inspection needs. Respectfully, Chuck Moore"

I had mold remediation performed in a closet in my home in April 2012.  After the mold was removed by a licensed remediation company, I called upon One Source Group. LLC.,  an independent firm from the mold removal company to perform air quality testing of the space that was remediated.  Mr Chuck Moore of One Source Group came to my home to do the testing.  I had plenty of questions that I wanted to ask Mr. Moore about mold remediation in general and about the final air quality testing process.  He was very patient with me and went above and beyond to offer in depth answers to all of my questions.  He treated me like I was his only customer and was very respectful. He was prompt and efficient in all aspects of the job performed. Mr. Moore is a consummate professional whom I would hire again in a heartbeat and would recommend his company to anyone needing such services. Thank you again Mr. Moore!

Tom was great. He tested the areas of visible mold and a couple of areas he suspected mold, but was careful to only do a few necessary areas in order to save us some expense. He explained ways we could fix a drainage issue and a leaky window in order to prevent further mold. He also recommended someone to fix the mold problem that was there. This person came in with a low estimate and was also professional.

After reading about mold online, we almost backed out of the house purchase. We called Tom, who talked everything through with us again. He explained the likely severity of the problem and our many options should there be any surprises down the road. He reassured us the fear of mold on message boards can get out of hand and that our issue was fixable. We are so glad he talked us off the cliff.

One Source also tested for asbestos. The test results indicated there wasn't any found in the popcorn ceilings, which was a relief. Soon after they left, we realized vinyl flooring had been glued to the original hardwoods below carpeting. Aware asbestos was sometimes used in such floors, we called Tom yet again. He offered to test a piece of the floor for the cost of the lab without charging to have the asbestos inspector return. Tom was very helpful, professional, and patient. We will be using him for any other future surprises during renovation.

Chuck kept me informed every step of the way, from sample collection, what to keep an eye out for, test results, all the way through final evaluation reports. Even when I failed to point out an area of concern during the initial service, Chuck gladly reviewed photos, provided advice, and reviewed the area upon a follow-up visit. He went above and beyond, performing a second radon test because the first had provided an abnormally low result. He was very helpful, very thorough, very trustworthy. I would certainly recommend him for environmental testing needs.

Overall, based on the "Please Describe in Detail" section, above, I would say that One Source made a minimum effort for maximum dollars.
Response from One Source Group LLC
"We are sorry that this customer had a bad experience. Based on the budget they gave us to work with, we had to target the area they requested and contrary to what they stated, A visual evaluation along with moisture testing was performed in all other suspect areas of the home along with other valuable advice for asbestos and LBP. Furthermore, the remediation area that we specified (water heater location) was a small job that did not require a fullblown workplan. It should be noted however, that after the customer requested it, it was provided SAME DAY. Bottom line we have a a great track record on Angies List and we hope that this ONE review doesnt afffect you decision to call us for our services. Furthermore, it should be noted that the person who wrote this review was not present during this inspection and it is in our opinion an impulsive post from second hand information at best. During the discussions on the work scope question it was discovered the client was hiring a company from San Diego to do this small job in Fullerton. We tried to give some advice as to why the SD company was asking for such an expanded scope for such a small job (i.e. obviously they didn’t want to drive all the way up from SD for a "free" estimate). As the saying goes "in one ear, out the other". I offered them some good LOCAL mold remediation firms they could call that would not have asked for this and caused the confusion in the 1st place. Lastly, we at 1SG take each and every project large or small seriously and we just wanted to set the record straight on this particular post."

March 17, 2012   Last year I was unfortunate enough to need a mold inspection for an apartment with a tenant that turned out to be a nightmare. Thank goodness I was referred to Chuck Moore at 1 Source Group (866)518-7658 http://www.1-sg.com   Chuck not only was competent in the work that needed to be performed, he also warned me ahead of time what I could expect from this tenant. She had moved in two years earlier and I had no problems with her until she turned awful. She said she was sick from toxic black mold, her dog was sick and needed vet care… on and on.   Chuck knew how to speak to the tenant, and as nice as she appeared to be, he warned me about what I could expect. Everything he said came to pass. Although there was no harmful mold in her apartment, she threatened to sue me for $28,000 over her health claims, inability to work, and relocation costs.   She stopped paying rent, and although she was evicted and ordered to pay the rent that was due, she then sued me in small claims court. Again she lost and I was awarded more money. Of course I never got a cent from her, but Chuck’s support in the eviction court and the small claims court was invaluable as an expert witness.   There is not enough good things I can say about Chuck from his knowledge, experience and helpfulness to his ability to work with tenants. When you hire him, you get the gold standard.   Sincerely, Rennie Gabriel www.ValleyVintage.com apartments
