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!"

"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."

Radon Detection and Reduction questions, answered by experts

In most states, radon testing companies don’t need to be licensed or certified by the state, but the companies that analyze the test results and develop radon mitigation protocols do. You should choose a radon testing company that suits your needs, but before hiring a mitigation specialist, check our state licensing tool to make sure the company is properly certified.

You'll need to test your home for radon after installing the mitigation system, then again every two years. If radon remains elevated, contact a licensed radon professional, either the contractor who installed the system or a different one, and have them evaluate the system. They may need to make some changes to improve its effectiveness and performance.

Sampling typically takes 1-3 hours, and depending on the provider, lab results are available within 2-7 days.

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

Properties should ideally be tested for radon every 2 to 5 years or sooner when changes to the property structure or ventilation occur that might impact airflow.
