"Very kind man and seem to be thorough; Upon moving in found some serious code violations. I contacted the company he fixed one of the problems he came out and fixed one of the problems for at his cost, no cost to me, I asked about the more serious code violation and he has not called me back. I would not use KK consultants again."

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!"

FAQs for radon gas testing projects in Pullman, WA

Radon is the second leading cause of lung cancer in the U.S. The gas seeps through cracks in foundations and collects in basements and other low areas. Once you breathe it in, radioactive particles lodge in lung tissue and do long-term damage. Because you can’t see or smell radon, the EPA recommends testing your home every two years—and after major renovations—to keep your family safe.

Yes—every home should be tested. The EPA advises doing it at least every two years and any time you remodel, buy, or sell. On average, one in 15 houses nationwide sits above the recommended limit, and the only way to know where yours stands is a formal test. The equipment simply measures gas levels and won’t change your indoor environment, so the process is completely harmless.

Certified radon professionals—often home inspectors or dedicated radon mitigation contractors—handle testing. These radon testing professionals follow EPA protocols and use calibrated instruments to check levels throughout your house. Hiring a certified radon specialist means results you can trust for real estate deals, insurance requirements, and, most importantly, your family’s health.

Inspectors specialize in measuring radon gas levels, while licensed mitigation contractors design and install the systems that remove it. If your test comes back high, your inspector can point you to a qualified mitigation pro who will size and install the right fan, piping, or other equipment to bring levels down.

No—standard home air purifiers don’t touch radon. They’re built to trap dust and pollen, not radioactive gas. If testing shows high levels, you’ll need a dedicated mitigation system that vents the gas from beneath your home to the outdoors. Relying on a room purifier alone won’t keep your indoor air safe.

Opening a few windows in your home might dilute radon for a short time, but the gas seeps back in as soon as they’re closed. For a lasting fix, you’ll need a professional mitigation system—often a sub-slab depressurization fan—that pulls radon from beneath the foundation and safely vents it outside.
