As an inspector with more than 4500 completed inspections, I run my business with one goal in mind - to perform the most thorough inspection I can so that you don't face unwelcome surprises. In addition to my home inspection experience, I am a former Chairman of the State Home Inspector Advisory Board which developed the Standards of Practice for Washington State. I am also a former member of the Washington State Building Code Council and wrote a short book for home sellers titled Surviving the Home Inspection. The inspection will include all the elements of the Washington State SoP. From top to bottom, I will inspect your home. If safe, I will walk the roof, crawl the crawlspace, and remove covers for electrical panels. Reports are completed on the same day and include digital pictures and video. Your comfort and safety in your home is my utmost priority.

"It seemed to go OK - he was on time and friendly. But, after the inspection we discovered that a number of issues had been overlooked or poorly evaluated. Through a series of unexpected circumstances, we've moved 4 times in the past 6 years - yuck! That, combined with the fact that we've owned about 10 houses over the years (including 2 ranches) has given us a lot of exposure to inspectors. This inspector just missed too many things & didn't pay attention to details. For example, the shop had an attic that was accessed by a drop down ladder. The inspector had noted that the roof was in poor shape, but he failed to climb the ladder to see if it had been leaking. He stated that "access to ladder was obstructed and he could not access the attic." But the realtor and I both had no trouble in dropping the ladder and crawling up for a look. There was no blockage AT ALL! Unfortunately, we didn't have a flashlight, so we couldn't see much. In my opinion, he just got lazy or in a hurry. His failure ultimately will cost us over $10,000 - the shop roof was leaking and now needs a full replacement. Had he simply taken the time to check this out - especially since he'd already noted the roof was in poor condition (which should have been a red-flag causing him to investigate further) we could have required to seller to address the issue - but he just blew it off and by the time I could look again (we lived three hours from home in question), and take a flashlight, the inspection period had passed. Access was unhampered, he just chose not to do his job and justified it by saying access was blocked. He failed in a number of other ways too (like a failure to conduct or even suggest radon testing). Very disappointed. If you want a quick, "once over lightly" inspection, he's your guy. If you need a detailed assessment of a property you're planning to buy, I would not recommend him - period!"

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. 

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.

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.

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.

Ideally, no one will live in a house with elevated radon levels, as prolonged exposure increases the risk of serious health issues like lung cancer. However, homes with radon can be made safe through mitigation systems, such as active soil depressurization. Testing for radon regularly and addressing high levels helps ensure a safe living environment.
