"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."

Whether you are buying or selling a home, getting a professional home inspection is vital. If you are a buyer, you need a clear picture of exactly what you are buying so there are no surprises down the road. And if you are a seller, you want a pre-listing home inspection to address issues now, not later. Newly constructed homes should also be inspected prior to closing and in the 11th month of the first year before the warranty expires. KEY Inspector, a local, family owned company, has the experience and qualifications you need. Kevin Yarbough with KEY Inspector is licensed to perform general residential home inspections, and is New Residential Structures (NRS) certified by the state of Virginia. Kevin is a NRPP Certified Radon Tester, and is also certified by InterNACHI to perform Home Inspections and Radon testing following their Standards of Practice. He also has over 20 years of residential remodeling knowledge and experience.

"An enormous shout out for the KEY Inspector**. -- He is a very likable, easy to get along with person. -- In addition, he is super charged with extensive experience; -- he utilizes incredible equipment to get an up-close view of hidden, hard to see places; and -- he is extremely effective while inspecting then captures the results with an on-the-spot digital report of the findings which are clarified with pictures, arrows, and notes. The report is also emailed. **Highly, highly recommend the KEY inspector. He continues to provide support even after the inspection. He is above the mark of A+."

Radon Detection and Reduction questions, answered by experts

You can buy DIY radon test kits from a home improvement store and conduct radon testing, but these tests are often inaccurate. No matter the result, you should supplement DIY testing with professional radon detection and analysis. DIYers only have access to passive radon tests, which aren’t as reliable as active tests that professionals use. Plus, it’s very easy for DIYers to make mistakes during testing, leading to inaccurate results. If you’re moving into a new home, have concerns about radon, or are due for an updated test, hire a professional. 

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.

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

DIY kits are available for basic testing. Professional services provide comprehensive results and recommendations.

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.
