Certified Mold Removal has been providing expert licensed and certified mold inspection, testing, removal and remediation services Since 1995! Not All Mold is Dangerous! Don't Let Other Companies Scare You! Call now and we can have a licensed and certified mold inspector at your home today!

"Alaert! I hired this company to test the air in my detached garage and paid $600 for the mold test. The results showed Cladosporium, which is one of the most common molds found both indoors and outdoors. What I didn?t expect was the remediation proposal that followed: over $45,000 in recommended work for a detached garage. In my personal opinion, the scope and price were extremely excessive for the type of mold identified. The quote included multiple rounds of fogging, containment, demolition, and even pages of alarming health claims ? including everything from depression to cancer ? that felt more like fear tactics than practical guidance. I?m not a mold expert, but after getting additional opinions, it was clear to me that the recommended work and the severity of the warnings did not match the situation. I chose not to move forward. If you?re considering this company, I highly recommend getting multiple quotes and doing your own research. My experience left me very uncomfortable"

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 Lansdale, 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.
