"Lesson learned. Always get an estimate. BEFORE the work is done. At least a digital copy. Arrangements for the project were made, with some one named Lynn, for the company to send someone to complete the work. We were quoted over the phone 4500-5000 which included a mold test. A sub contractor with an entirely different company (National Mold Company) was sent. When the contractor arrived, he stated that the job would be much more simpler than first thought. This led us to believe that the job would cost less, no. All said and done, they charged $5500. All said and done, it's almost like no work was done. The stains and the smell are still there. Only one actual board was taken upon the attic room. The ceiling in the bedroom was primed and painted but are still visible and have a funky smell. At this point I'm going to. Do what we should have done; Do the job ourselves. Just now with $5500 less dollars in our pockets. A detailed receipt was not given even though it was requested."

The preferred provider of Home buyer, termite and radon inspections in the area. Fully licensed and insured and never forgetting that above all…we work for you!!! "Educating home buyers so they can make better decisions."

"Jason with Eagle Inspection is, without a doubt, THE BEST home inspector out there! He doesn’t just do his job—he CRUSHES it! Jason goes above and beyond every single time, and I couldn’t imagine trusting anyone else. As a Realtor, I use Jason for ALL my clients. Whether it’s a cozy South Philly rowhome or a stunning $1+ million property in Huntingdon Valley, Jason is always my go-to. And of course, he’s the only person I trust to inspect my own properties. I’ve been working with Jason for FIVE YEARS, and I honestly feel like I hit the jackpot finding him so early in my career. He’s the total package—knowledgeable, professional, and incredibly kind. In no particular order, here's just a glimpse of the exceptional things he has done for my clients: He found termites in my home—hiding behind a light switch of all places! I can’t imagine any other home inspector catching something so hidden and specific. He goes the extra mile by reviewing contractor bids and making sure my clients aren’t getting ripped off. Who else does that? No one! And Jason doesn’t charge for this incredible service! He works evenings and weekends, so my clients don’t have to rearrange their lives to schedule an inspection. One time, he even skipped an Eagles game (gasp!) because my client was leaving the country the next day. Talk about being reliable—Go Birds! Jason invests in top-notch gear, like advanced water detection tools and a high-tech drone, ensuring in-depth home analysis! Jason is an absolute powerhouse of knowledge, and his expertise is in a league of its own! While other home inspectors receive a quick certification, Jason brings the next-level experience of being a former builder. He often spots details other inspectors often miss. He does an excellent job at explaining everything to homebuyers. He makes them feel confident, informed, and READY to become homeowners. If you’re looking for the most thorough, reliable, and all-around incredible home inspector, JASON IS YOUR GUY! I recommend Jason with my whole heart. 10/10, A+++!"

Radon Detection and Reduction questions, answered by experts

The natural breakdown of uranium in soil, rock, and water can cause radon to appear in a home. The gas seeps into homes through cracks in foundations, walls, or floors, as well as through gaps around pipes or construction joints. Radon levels are influenced by soil composition, building materials, and ventilation. Poorly sealed or airtight homes can trap radon, allowing it to accumulate.

Mitigation reduces radon levels, protecting your health and complying with safety standards.

Installing a mitigation system reduces radon levels, which can cause lung cancer, providing peace of mind and long-term health benefits. It can also increase your home’s value, as many buyers prefer properties with radon safety measures in place. The investment is relatively low compared to the potential health risks associated with prolonged radon exposure.

Radon enters your home when warm air begins to rise and exits through the roof, creating a vacuum that pulls cooler air from under the foundation. Part of that air is radon, which is an invisible, odorless gas that develops naturally when radioactive particles are deep within the ground. Those particles usually come from decaying matter in soil and rocks.

DIY radon detection is possible using over-the-counter test kits, but professional testing can provide more accurate assessments, especially in cases of high initial readings.
