"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

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

Your radon fan needs to operate 24/7 to be effective. The only time the fan isn't operating is during its replacement. Radon levels in the home can increase within hours if the fan stops working or something obstructs the stack vent. Fortunately, radon systems require no downtime maintenance between fan changes.

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. 

Keeping radon from getting into your home is much better than having to get rid of it once it's already indoors. While there may not be a way to fully prevent radon from getting into your home, there are things you can do to reduce the gas's ability to enter. 

Sealing foundation cracks and openings can help keep the gas from seeping inside. Improving air flow, such as by opening windows, can also be helpful. If you're building your home from scratch, talk to your contractor about using radon-resistant construction to keep the gas out.

Costs depend on test type, home size, number of testing locations, and whether follow-up testing is required.
