"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."

For over 30 years we have assisted homeowners through the property claims process and have bolstered our business based on our efforts to not only get the greatest settlement possible for our clients, but also by conducting ourselves as courteous professionals who treat our customers with a great deal of respect and consideration.

However, given our attention to detail, knowledge of construction and vast amount of experience we are fully capable of walking you through these no doubt difficult to deal with situations and we can help you come out of it with a great sigh of relief and often a notion of surprise at how great and quick a settlement can come from the claims adjusting process. Give us a call for a free home walk-through and policy evaluation!

The team went above and beyond in every aspect?from assigning a dedicated representative to handle my claim, to guiding me through the entire process from start to finish. Every staff member I interacted with was friendly, professional, and extremely helpful whenever I had questions. I have used this company on three separate occasions, and each time they exceeded my expectations: When a neighbor?s tree fell on the back portion of my home.

Radon Detection and Reduction questions, answered by experts

Radon testing costs around $450 on average, but you could pay between $150 and $800 for testing, depending on a few factors. The size of your house is one of the most significant cost factors, as your radon professional will have to set up additional tests for homes with larger footprints. The type of test can also have an impact on the cost. Finally, some radon testing companies will include a recommended protocol for radon mitigation, while others might charge $50 to $100 extra.

A radon test has no effect on humans—only the radon in the air does. The test does not redistribute the radon that is already present so yes, it’s safe to be around the testing kit even if it isn’t safe to be in the room itself. The test absorbs and measures the radon, but doesn't absorb enough of it to make the room any safer.

The soil beneath your house is most likely what’s causing an increased level of radon. This is because soil holds radioactivity for a long time and it’s also what most buildings are built on. Another common source of radon is water from a source that hasn’t been through periodic radon tests, such as well water. Over time, the radon from the soil can inhabit other parts of your house like the foundation or plumbing.

Radon detection is crucial as prolonged exposure to radon gas, a leading cause of lung cancer, poses significant health risks in residential environments.

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.
