"We had our radon fan replaced by Radon Bros in January 2025. From the beginning, the new fan was noticeably louder than the previous one. At that time, the technician advised us that the increased noise was due to the fan being stronger than our prior unit. Over time, the fan became increasingly louder and ultimately stopped working in early December 2025. When a technician returned to replace the fan, we were informed that the fan originally installed was defective and that Radon Bros had stopped using that manufacturer due to known issues. Despite this, we were charged a $99 labor fee for the replacement. We do not understand why we were responsible for this charge when the failure was due to a defective fan that your company was already aware of and no longer installs. We felt we had no choice but to pay the $99 in order to have our radon mitigation system restored and functioning properly. "

"We recently worked with Flood Solutions after our basement flooded, and Megan—our inspector and project manager—was incredible. She was thorough, patient, and took the time to explain every step of the process, which meant a lot as an allergy sufferer worried about proper remediation. She honestly deserves her own show on mold education! When the team arrived, they were organized, detailed, and clearly cared about doing things the right way. Matthew and the crew also did a fantastic job finishing everything and making sure we felt informed and comfortable throughout. We can’t recommend Flood Solutions enough. If you need a trustworthy team during a stressful time, call them—and hopefully you get Megan, she’s a gem!"

We’re Jim and Mike Allen, brothers and co-owners of TermiGuard Services and Fenwick Building & Renovation. With our 50+ years of combined experience, we can promise you that you're in good hands. One of the biggest challenges we face as homeowners is finding the right contractor to deal with issues which arise – one who has the requisite knowledge, skills, and experience. A contractor who will answer your calls and then do what they say they’d do, when they said they would. A contractor you can trust, and who will actually give you a no-nonsense warranty on his/her work. We’ve built TermiGuard Services & Fenwick to be effectively different from the rest – embracing and living the principles and values we grew up with – treating people the way we’d want to be treated. And frankly, we’re tired of how so many other companies treat customer service as unimportant and how they take customers for granted. As consumers ourselves, we’ve felt the pain from the evident lack of caring and regard for the concept of old-fashioned, customer-centered service. To that end, we offer you a family of home services including, real estate repairs, pest, termite & wildlife control, water intrusion inspections, mold treatment, waterproofing, structural & foundation repairs, property & water damage restoration, and crawl space encapsulation services – to name just a few… Bottom line – we’re first aid for your home or building, and we’re dedicated to providing you healthier living…

"Very dissatisfied with my service and lack of professionalism. Will not be recommending or reusing this company again."

FAQs for indoor air quality testing projects in Landenberg, PA

You should test your home's air quality if you or your family experience health problems like allergies or respiratory issues, as these could be linked to indoor contaminants. Also, consider testing if you're concerned about mold, radon, carbon monoxide, or if you've recently had home construction, demolition, excavation, or remodeling that could have released chemicals into your indoor air.

An indoor air quality test typically takes one to three hours to complete. After the inspection, you'll receive a detailed written report within two to 10 days. The evaluation includes comprehensive air sampling from all designated areas in your home. Your specialist will review the findings with you and provide clear guidance on steps to take if any issues are found, helping ensure your indoor environment meets health and safety standards.

A certified indoor air quality consultant or inspector is the right professional to perform your indoor air test. While some home inspectors have certifications, they often subcontract this specialized work to trained professionals with advanced tools. This expert will thoroughly evaluate air samples from every area in your home and clearly explain the findings to you. Be sure to confirm your tester's credentials before scheduling your service.
