"Prompt response and came over within hours of contact. Very knowledgeable, professional and provided good guidance on preventing future mold and mildew problems in basement areas. Very pleased with the service and will be having them back for additional mitigation when some precursor work is complete."

"Steve was great. We had a mold inspection done and Steve came to quote a remediation and instead gave us very useful tips for how to address the smaller issues ourselves, recommended one repair and offered to come back after to check things out before he did any work that would cost us more. He clearly has the best interest of his clients at heart and we would absolutely use AdvanataClean in the event that we needed remediation done and would recommend Steve to anyone looking for an honest and fair estimate."

"Eric was great to work with. He worked with our schedule, really looked around to make sure that the full amount of mold was removed, and was extremely thorough and knowledgeable. I hope to not have a mold issue in the future, but if I did, I would absolutely use Eric again."

"I would very much recommend Mold Testing and Remediation LLC. for the fine work they did. Their estimate was spot on, their workers were polite, thorough, clean and made a point to explain exactly what they were doing, step by step. They showed us their work at the end of each day, asked us to inspect and approve it and gave us a verbal time estimate of when to expect the project to be done. Their attention to detail and communication was very much appreciated. The window of time they estimated for completion was held to and the overall quality of the work was stellar."

"Working with Jim, was like working with trusted family. Jim went above and beyond, he investigated and determine where the issue stemmed from vs just cleaning up and walking away. Jim and his team did an excellent job and was truly a lifesaver. I would hire Jim and his team without hesitation and would advise anyone who needs the services they provide to look no further. Often times we can find ourselves over a barrel when unexpected disasters happen in our homes as whatâ s most comforting is knowing you are working with honest, good people. Thank you"

"We couldn't be more impressed with the 1-800-Water Damage team. They set the bar in their industry through unrivaled expertise, professionalism, value, and integrity. Our story: We had extensive water damage from pipe failure in our kitchen. They were at our house within the hour. We were immediately impressed by their insight into the nuances of the problem. Justin and others on the team rapidly implemented a mitigation strategy with surgical precision. We spoke with some of their competitors who both proposed expensive highly destructive mitigation plans that could have incurred tens of thousands of dollars of damage. In contrast 1-800 Water Damage was able to access and clear every inch of our house reached by water while preserving expensive cabinets, granite, and other home structures we wished to save. They then dried, treated, and sealed things up setting the stage for successful restoration. This team knows their trade and was just a delight to work with. Truly lifesavers. We can't say enough good things about them. A+. Clarification on Geography: Although I now live in Ann Arbor, MI, the work was done by Justin/ his team working out of this 1-800 Water Franchise in New Hampshire, so I have posted under this location."

"I moved into a condo on April 1st and bought a new washer and dryer a couple of days later. The dryer was not drying the clothes thoroughly even after running it two or three times. I had a feeling the vent was clogged with lint. I called Superior and they were able to come out within a week and they gave me a good price. They showed up on time and did a great job. I couldn’t believe how much lint they were able to remove. Dryer works great now!"

FAQs for toxicity and mold removal projects in Newton-junction, NH

Remediation should keep mold from returning as long as the moisture source is eliminated. Fix leaks, control humidity, and replace water-damaged materials, then schedule periodic inspections to stay ahead of new growth. With those safeguards, your home can stay mold-free for the long haul while protecting both health and property value.

Most pros recommend leaving the home while they work on mold remediation. Removing mold stirs up airborne spores that can aggravate respiratory issues, and contractors can work more efficiently in an empty space. A short, temporary relocation keeps everyone in your family safe and lets the crew finish the job without interruption.

Mold shouldn’t return once the moisture problem is fixed. Stay vigilant: repair leaks right away, keep humidity below 50 percent with a dehumidifier placed in damp areas, and improve ventilation where needed. Routine checks for leaks and mold and quick repairs go a long way toward keeping your home mold-free.

Mold spores can trigger nasal congestion, throat irritation, coughing, wheezing, eye irritation, or skin rashes. People with asthma, allergies, or weakened immune systems often feel the effects sooner and more intensely. Some molds also release mycotoxins linked to serious respiratory or neurological issues. Swift remediation and better ventilation are the best defenses.
