Description of Work: RTS Environmental correctly identified and corrected a damp wall issue caused by a leaky pipe. The were professional, punctual, and to the best of my knowledge followed all EPA rules regarding mold and lead abatement. They did this as a rush job while a tenant was on holiday and were pleasant despite working through the holiday. I would recommend them again.

Description of Work: I recently purchased an older house. I was fairly concerned since my husband and I had already started a bit of construction on the house and was worried that there was significant amounts of asbestos. The inspector looked in every room of the house and indicated to me the materials that are most likely to contain asbestos and how to properly remove them. The inspector helped to address my concerns and indicate how to proceed with renovations taking the proper precautions to protect ourselves in the future. Very friendly, personable and helpful!

Description of Work: Needed house checked for mold and other allergens. Absolutely professional and honest approach. Suggested we needed remediation based on thorough inspection, but insisted on lab tests which were all clean. If the lab results warranted action, absolutely would have engaged RTS to do that work.

Description of Work: Answered my questions honestly and completely - we determined that using their services would be overkill. Really appreciate him taking the time to talk to me and give me a professional opinion. He could have easily convinced me that we should use them - but - if we ever have a real need in the future, now I definitely will.

Response from RTS Environmental Services
There is so much scary misinformation and exaggeration to many of these environmental scenarios / issues that helping folks to better understand whats real and best approaches first, is central to our mission and drives our commitment to consumer advocacy. Prevention, better understanding and practicality are the approach. Sometimes there is reason for alarm, but nobody should make decisions from a purely emotional point of view. Glad to be of service.

Description of Work: We had concerns about mold that appeared in a section of our attic ceiling. Paul Ramsey conducted a mold testing/inspection of not only the attic but the entire townhome. We were pleased to hear Paul say that the mold in the attic was limited and will not cause an indoor air quality issue. He also indicated there was no sign of mold in any other part of the home. Paul did not recommend mold remediation work, and said we can simply clean the plywood sheathing with Tilex or a similar agent.Paul was extremely helpful in helping us find the root cause of the attic mold which was the humidifier attached to the furnace. The humidifier level was set too high causing condensation in the attic. He recommended turning the humidifier off for the winter and provided good instructions on how to set the attic fan humidstat at the correct level. Paul was very knowledgeable about the subject in question. He has a very professional, pleasant demeanor and is thorough in conducting inspections. We highly recommend him and his company to anyone who is experiencing mold problems in their home.

Description of Work: I needed an evaluation of the finished half of my basement; the other half had already undergone mold remediation by a different contractor. Mr. Ramsey and I walked thru together as he made his observations. He then wrote a detailed list of things I needed to do get rid of the problem he saw: dust, as well as to prevent mold issues. Seemed to be the 'objective' look promised, rather than an attempt to sell more-expensive mold abatement.

Description of Work: An inspector came and went over our house thoroughly for mold and dust including checking the crawl spaces, storage areas, sump pump area, and wall of lower story that is partly under ground level. He made practical, non- alarmist recommendations (dehumidifiers, clearing and cleaning certain areas, aggressive dusting) but did not try to sell us unnecessary, expensive services or remediation. We were very satisfied.

Description of Work: RTS removed the asbestos from the heat pipes of my furnace, cleaned up the area, had the area inspected, reinsulated the pipes. When they were done, everything looked really nice. RTS actually used another company to come and do the work. This company was licensed to do asbestos removal work and provided me with a copy of the inspection certificate.

I called RTS to inspect my basement for mold due to a previous water problem. Paul Ramsey returned my call and we set up an appointment for within a week. Paul arrived on schedule and did the inspection and found only very minor mold which he said could be cleaned easily. He said he did detect some dampness which he felt was due to the limited air circulation in the basement and he recommended installing a humidifier. He also identified areas which a home inspector would cite as concerns and suggested how those could be fixed. He made a number of good suggestions for treating basement walls and floor that would not only retard mold growth but also improve the overall appearance of the cinder block walls for any future sale. Paul provided a written report listing all his suggestions.

Actually I recommended a Dehumidifier (I know this was a typo) but I want to make sure no one thinks I would recommend a humidifier when we want to decrease relative humidity. By the way, adding a simple circulation fan to a subject space or area also helps to make existing dehumidifiers more effective because it helps to mix and move air and the over all relative humidity is that much drier.

I was able to get an appointment within a week. Paul Ramsey arrived on time and did a thorough examination of our house (3 levels). He was careful about walking on light colored carpets. He explained what he was doing at each step and readily answered questions. At my request he paid special attention to the attic where we have moisture buildup. He took several pictures to show the problem areas that I could not see before (currently ice crystals are forming on the inside roof decking). He discovered no mold but several potential problem areas. He recommended some steps to prevent problems. He was very pleasant, very responsive to questions, and very professional.
Description of Work: RTS performed a check of the house for moisture and mold. Special attention was given to the unfinished attic which has ventillation problems.

We were able to quickly schedule our appointment with Paul to evaluate our basement for mold and asbestos issues. Paul arrived on time for the appointment, and gave us an hour heads up that he was on his way. (My husband had written down that the appointment was for the next week, however I am certain that this was probably a communication error on my husband's side. In any event, it worked out better to have Paul come when he did.) Paul introduced himself to me and kindly let my preschooler talk for a few minutes about our cat, before he got down to business and reviewed our concerns from the preliminary phone call. Paul then evaluated our basement, asking questions about our history (water issues, etc.) and what our plans were for remodeling the basement. He pointed out some common mold we had on our old windows, explained that the mold was not toxic and why it was growing there. He also evaluated tile we had on the basement floor and assured us that it was probably not asbestos and offered to have it tested (for an additional fee). We declined the test after Paul explained to us when asbestos is a concern (pulverized over a large area) and that our tile was in sound condition throughout and thus not a concern since we were planning on leaving it in place and covering it with carpet. He gave us further suggestions on how to contain and eliminate mold growth, including what paint to use on the walls and installing a dehumidifier in the basement by next spring. He even gave us a good tip on how to purchase a dehumidifier at a lower cost. Paul also took a look at our master bathroom and again offered suggestions on how to combat a common, non-toxic mold there. Throughout his visit, Paul was thorough and very clear in his evaluation and suggestions. Now we feel that we have the peace of mind to pursue our minor remodel of the basement. Money well spent!
Description of Work: We contacted RTS Environmental Services to evaluate our basement for mold and asbestos primarily for planning purposes prior to a limited remodeling project.

To make sure, I did not forget any areas of concern that I have noticed in my house, I wrote out 3 pages of notes of different, unexplainable things that had occurred in the last 7 years. Paul had no problem going through my lists and reading all my concerns. Some had nothing to do with moisture or mold, but he was very kind and patient with me. He covered everything so thoroughly, missing nothing, and explaining how to resolve everything. He spent at least 2 hours with me, it was most productive. Two hours that I have experienced with a Professional. Paul knew exactly what he was doing, he's extremely educated in his field. Thank You. Paul, you are truly a blessing and give a whole new meaning to excellent customer service and now this Mom can sleep better at night.
Description of Work: A couple months ago I got a Digital Thermo-Hygrometer to put down in my basement because I started noticing some "mold" coming through some painted walls. This month, the Mold Alert was making a loud alarming sound and the red unhappy button was lit up. This scared a single mom, like myself and I was so worried that I might be living in a home that was unhealthy for my family. I knew nothing about mold and had no idea where to even find someone to help me. Then I read about Paul and his company.

It went very well. He was able to come to the house on the same day I called or next day (I forget exactly). He was very professional. He took no more time than necessary but didn't rush through his work. He took time to explain things to me. Bottom line: I had a tough case of leaf mold on the exterior and found unwanted moisture in one interior location.
Description of Work: I contacted RTS to have my home inspected for mold. He examined both areas that I pointed to and other areas of the house where mold could be found. He used his device to detect moisture. He identified the type of mold found on the house exterior and suggested how it might be remediated given its tenacious history on the house. He did not perform remediation, which is not one of his services.

ACTUALLY WE DO PERFORM, MOLD REMEDIATION, BUT WE ARE THERE TO PERFORM AN OBJECTIVE AND THOROUGH INSPECTION AND ANSWER ALL OUR CLIENTS QUESTIONS, BUT WE ARE NOT THERE TO SELL REMEDIATION. WE CAN INFORM OUR CLIENTS FULLY REGARDING WHAT REMEDIATION IS AND WHAT IT MEANS, BUT WE WILL ONLY PRODUCE A REMEDIATION PROPOSAL UPON REQUEST. WE DO NOT WANT TO CREATE A CONFLICT OF INTEREST AND PROMOTE SERVICES WHICH MAY NOT BE NECESSARY. IN MANY CASES, MOLD REMEDIATION IS NOT NEEDED BUT SIMPLE CLEANING CAN BE EFFECTIVE. PAUL RAMSEY
