"We recently had Dan come out to give us a free quote for two windows that were leaking and showing some minor water damage. From the moment he arrived, Dan was professional, friendly, and incredibly thorough. He took his time inspecting both windows and clearly explained where the moisture was building up and what signs to keep an eye on moving forward. What really stood out was his honesty—rather than pushing unnecessary repairs, Dan let us know that the issue could be mitigated on our own by using dehumidifiers and keeping the window areas clean. He walked us through exactly where the buildup was happening and gave us practical tips to manage it ourselves. It's rare to come across an honest company that is not money hungry.

MoldGone is a full service mold inspection, air quality testing, remediation, and reconstruction company with over a decade of experience. Our inspectors and technicians carry the highest and most recognized certifications in the industry. Whether your are a residential or commercial customer seeking mold testing or remediation services you can be assured that the project will be professionally managed and properly certified. There are many companies that offer mold remediation - make sure that the company you choose has an industry recognized mold remediation or inspection certification such as the American Council of Accredited Certification (ACAC) or equivalent. MoldGone is unsurpassed in its commitment to customer service excellence, provision of only the highest caliber service, and providing unsurpassed value in every project or inspection delivered. MoldGone's customers have ranged from the residential homeowner to private schools and churches. In fact, when the Sisters at a private Catholic girls school in the Washington, D.C. area needed a company to treat mold in the Sister's private archive room, complete with 100 year-old manuscripts, they entrusted MoldGone, LLC to do the project. On another project that involved removing mold from a 30 foot ceiling above a filled indoor pool, when the scaffolding company wanted several thousand dollars to build the necessary scaffold to reach the treatment area MoldGone built its own providing the customer significant savings. At MoldGone, LLC. we constantly strive to find the most cost effective way to fully address each and every mold condition. MoldGone technicians are trained specifically for mold treatment and remediation. They are also required to have construction experience since many of our projects involve demolition and reconstruction. Technicians are held to the utmost highest levels of quality with each project receiving a thorough walkthrough by management before it is deemed complete.

"MoldGone was somewhat hard to deal with but ultimately agreed to work on this until the air was normal and they had good reviews so I hired them. They did the first treatment and I had an air test done. It showed there was still high mold levels. I immediately asked them to return to fix it--as we had agreed. Jay argued and argued but eventually agreed to. On the day agreed, they claim they came but could not work since no one answered the door. We had already agreed I would not be there--and that both doors would be open so they could begin. Jay forgot to tell the workers AND he failed to call/e-mail me while they were there to ask me. So I am out ANOTHER $300 for the hotel and still no mold remediation. I again sent e-mails asking when they would come back. Jay admitted the communication failure was his fault but still said he would not reschedule the job. This time Jay refused to do the job--instead offering to just do "cold fogging" Next, Mike Mulieri(VP of the company) entered the picture. He assured me he would resolve the problem. Instead he made it worse. He dragged it out, argued back and forth with Angi and still refused to refund money or do a re-treatment of my place. I view MoldGone as slick, dishonest folks who try to talk their way out of any problem- but not actually remedy their mistakes. Now I'm on my way to the courthouse."

As a family-owned local business, with over 25 years of experience helping customers with their water, fire and mold damage needs, satisfying our customers has always been our top priority. We take pride in what we do and will treat your property as if it were our own.

"We had water and mold damage to our family recreation room in the basement from a leak in the main water line entering our home. There was water and mold damage to a section of the carpet in the rec room. We hired ServiClean to do mold remediation service. Alfredo, the estimator, also detected possible moisture behind a section of the wall paneling, which, he advised, should be addressed. The ServiClean crew of Brian and George set up a containment chamber around the affected area along with other equipment, removed the section of damaged carpet and wall paneling, and applied antimicrobial to the area. We were very pleased with the whole experience and the work done. Everyone was very nice and professional from Lilian with her advise and help on insurance claims, Alfredo with his meticulous explanation and documentation of the process and the damage, and the Brian and George for their work and courtesy. I highly recommend their services for water damage and mold remediation."

Radon Detection and Reduction questions, answered by experts

Professional radon detection involves placing test kits in the lowest lived-in level of the house for a period, usually 48 hours to several months, followed by lab analysis of collected data.

Properties should ideally be tested for radon every 2 to 5 years or sooner when changes to the property structure or ventilation occur that might impact airflow.

Using an air purifier in your home or basement isn't an effective way to reduce or mitigate radon. Radon is an inert gas, meaning it doesn't react with other chemicals and can't be filtered the way particulates can be. While an air purifier can help improve your indoor air quality in other ways, don't rely on it to reduce radon.

Radon testing costs around $450 on average, but you could pay between $150 and $800 for testing, depending on a few factors. The size of your house is one of the most significant cost factors, as your radon professional will have to set up additional tests for homes with larger footprints. The type of test can also have an impact on the cost. Finally, some radon testing companies will include a recommended protocol for radon mitigation, while others might charge $50 to $100 extra.

Use a radon test kit or hire professionals to conduct a detailed assessment of radon levels in your home.
