Inspectioneering, LLC is a Home Inspection company serving the greater Pittsburgh and surrounding areas. All inspections are performed by a nationally Certified ASHI Inspector. Our Inspector is a graduate of the American Society of Home Inspectors School at Cincinnati State Technical Community College for Home Inspection. He has completed an apprenticeship under a licensed Structural Engineer and has years of hands-on experience in all phases of the construction field, as well as performing home inspections. Also having been Owner/proprietor of a construction company, gives our inspector an advantage over most home inspection companies as far as knowing exactly what the client expects and actual construction experience. Buying a new home is probably the biggest investment you'll ever make and it is a decision that will affect you for years to come. The process can be extremely stressful and confusing. And of course, there is always considerable risk involved when making such a large purchase decision. A professional inspection will significantly reduce your risk and help make the entire home buying process easier and less stressful. We truly enjoy assisting our clients in this process as customer service is our highest priority. Our inspection report is a computerized, reader friendly document which includes pictures taken at the property site as well as illustrations that help our clients to understand the condition of the property. In most cases, our clients are able to view the report at the end of the inspection or on the next day at the latest. We strongly encourage all of our clients to accompany us during the inspection. You should feel free to ask the inspector any questions you may have during the inspection process. The inspector will point out deficiencies within the property and explain the cause of the concern. The inspector will also highlight the positive aspects of the property. Plus, we will explain what routine maintenance is needed to keep the house in top working condition. Along with the information provided during the inspection, as well as a comprehensive report, not only will you be armed with the confidence to make an educated decision on the purchase of the property but how to maintain the systems that encompass your future property. Our inspector enjoys his profession and his thoroughness shows it. We promise you will have a pleasing experience throughout the whole home inspection process and look forward to working for you.

"I had an outstanding experience working with Rob. He was incredibly prompt, responsive, and professional throughout the entire process. The inspection was extremely thorough, giving me real peace of mind. I would and can confidently recommend Rob to my closest friends and family—he’s a thousand times over the person you want to ensure your home or the home you are thinking of purchasing is safe and sound."

"Scott from Landmark Inspections performed a home inspection of the home my husband and I are purchasing. We are first time home buyers and this is our first home inspection. We were very impressed with Scott from beginning to end. Before the inspection, he was responsive and communcative, answering every one of our phone calls and emails. The inspection was thorough and Scott and his trainee inspector (also Scott) took the time to answer our questions and explain everything they were doing/finding. The inspection did not feel rushed or like Scott was trying to get through it to move on to the next. The report he sent us (48 hours after the inspection, great turn around time) was very throrough, contained useful information about our future home, and clearly laid out a heirarchy for recommended repairs. We also got a termite inspection, sewer scope inspection (which was also performed incredibly professionally by Melvin from Knox & Knox Solutions), and raydon test. In total, we paid a lot of money for these services, but it was money very well spent. We would not hesitate to recommend Scott, Landmark, and the other service professionals with whom he contracts."

"Nick was extremely thorough and knowledgeable. He went well above and beyond my expectations for a home inspection. Described in detail every potential issue from the absolute minor to the major. Nick's attention to detail was so good that he even pointed out how the HVAC contractor used the wrong kind of tape to affix the ducts to each other. He also has a lot of knowledge about the area, its history and how that affects the construction of the old homes that are so common here. I was absolutely blown away by Nick's work and strongly believe that no one should ever buy a house without having Nick and Strong Foundations inspect it."

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. 

Yes, radon testing is absolutely necessary if you suspect the presence of this hazardous gas, and the Environmental Protection Agency (EPA) recommends testing for all homes in the country. Radon is a pervasive natural gas that can leak through your home’s foundation and seep into the living areas. Unfortunately, the gas is highly carcinogenic and is the second leading cause of lung cancer. Radon testing is crucial for keeping you and your family safe from harm, so hire a radon mitigation specialist to test your home if you suspect its presence in your home.

What is radon? It’s a radioactive gas that naturally occurs in the ground, forming as uranium and thorium decay. It has no color or odor, so you don’t know if it’s seeping into your building’s foundation. Regular exposure to radon gas increases your chances of suffering from lung cancer. Radon testing measures the air inside your house for the presence of radon gas. If detected, the test will measure the severity of radon levels in your home’s air.

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.

Costs for radon detection services typically range from $150 to $250, depending on the testing method and whether a professional assessment is required.
