Serving Mendocino, Sonoma, Napa, and Lake




Welcome to Housecheck Inspection Services, beginning our seventeenth year, and dedicated to meeting your highest expectations for a home inspection.   Housecheck is locally owned and operated, not an out-of-state franchise, nor a company of minimally qualified employees or subcontractors.  You can be confident in knowing what and who you are getting.


I am Byron Duerksen, an ASHI Certified Inspector with the American Society of Home Inspectors,  and a Board Certified Master Inspector with the International Association of Certified Home Inspectors.  Along with the highest level certifications and advanced continuing education, I have the most experience of any home inspector you can find.   I am an FHA/HUD Consultant and Inspector as well as a former City Building Inspector.  Also, I am a Certified Thermographer utilizing a thermal imaging camera to see what the eyes cannot.


Choosing the cheapest inspection could be the most expensive mistake you'll ever make.  Home repairs can be some of the costliest expenses consumers face.  The few dollars you think you could save may cost you thousands of dollars down the road because of missed or overlooked defects, some of which can injure or even kill you.  When it comes to any home purchase, the best doesn't cost -- it pays!  This is your last opportunity to gain information and understanding on a property which is a major long-term financial commitment.


If an inspector has no insurance specifically for home inspecting, you are at risk for potential undisclosed issues.  You have a lot of home inspectors from which to choose and you also have a lot to lose.

I was called in to re-inspect two different properties within a 2 mile radius of my house.  In the first house, the new owner had to put on a new roof that cost him over $12,000 even though the original inspection report  stated "Roof Condition - AS"  (transalation: appears serviceable).  Another new buyer had literally months of sewage under her house and the two week old inspection report stated "Crawl Space - AS."  She paid $1,350 for plumbing.   Incidentally, I do not use check boxes or secret codes, just plain English along with pictures.

Judge the home inspector by the quality of the Inspection Report which should speak for itself.  A professional report is well written, skillfully prepared, and leaves nothing to your imagination.  It should be well organized and systematically cover every room, component and system.  It should not require anyone to interpret it.  Some reports can be a disorganized volume of comments and pictures, with redundancies as well as omissions, that will leave you confused and unsure.

My reports are specific to your property with no fillers added.  They are designed to walk you through each area of the house and show you what I saw and report on it right then and there.

You couldn't put a price of your family's health and safety.  Your home inspection costs very little but it will tell you a whole lot.  It's worth much more than the inspection fee.  My fees are reasonable and affordable, and depend on the perceived amount of time it will take to inspect the property and to produce a fully documented report.

Assuming that you will get the same level of inspection and comprehensive report regardless of the fee is a pitfall you should avoid.  That simply isn’t true.  Shopping for quotes doesn’t begin to tell you what you need to know.   You need to get the most for your money.




As a professional, I maintain my long standing memberships in the American Society of Home Inspectors (ASHI) and the National Association of Certified Home Inspectors (NACHI), the two largest and most prominent national home inspector associations who set the standards for industry-wide protocols.

As a former contractor, I can tell you that home inspecting demands far more detailed education in every discipline than a general contractor.  A professional home inspector must possess a unique combination of disciplines, skills and education involving many elements that are particularly complex in order to perform the very detailed job of investigating a home’s structure and components.


To make sure you’re not buying a money pit, you need a professional home inspection before you commit.

A home inspector who does not require a signed a legal contract for an inspection has NO insurance and you are at risk for any potential errors or oversights in the report.  Without an Agreement and attached Standards of Practice, you do not know what you are getting.  We stand behind every inspection we do with errors and omissions insurance and with a 90 day warranty. 

The importance of having information that is accurate, complete, and unbiased should not be underestimated.   An inspection report is to provide you with total disclosure before you close escrow, to let you know what you are buying, before you buy it.

Continuing education separates a professional home inspector from all others.   I have attended Conferences and Seminars all over the United States to obtain advanced education.

I use state of the art equipment: tablets, drones, infrared camera, laser devices, and the most sophisticated software utilizing the Cloud, in order to conduct the highest quality inspection and produce the finest report available.

On a personal note, I have lived in this area for 20 years, have participated in building homes through Habitat for Humanity, am active in my church and have been on a local School Board for six years.


Our main focus is to provide FULL SERVICE for our clients.  We continually strive to improve our customers’ home inspection experience, performing high compliance inspections, and providing a comprehensive, detailed, easy to understand report, unlike any other.  We include these additional services at no cost to you:

Free! WALK-AROUND FOLLOWING INSPECTION - Following my inspection, I invite you to walk around with me to discuss what I have found, explore remedies and to answer any questions you have.  There is no time limit placed on this.

Free!  THERMAL IMAGING DETECTION - By utilizing my infrared camera, I can detect costly leaks and potentially dangerous electrical hot spots. 

Free!  90 DAY WARRANTY - You will have a 90 Day Limited Structural and Mechanical Warranty from American Home Warranty, from the date of the inspection. 

Free!  ERRORS AND OMISSIONS INSURANCE - Backed by general liability as well as errors and omissions insurance.

Free!  INSPECTION REPORT BOOK - In addition to providing you with the PDF of your inspection report, I will mail you a printed copy in a plastic cover for easy reference.  

Free!  SAFE HOME E-BOOK FOR MAINTENANCE - And, finally I will send you a valuable 225 page e-book.  This book is designed to provide you with tips and information to keep your family safe and your home in top condition.


"You simply cannot find a better home inspector anywhere, at any price."


Let me tell you what you need to know when choosing a home inspector.  There are no regulations in place for home inspecting in California.   In most cases your real estate agent will give you the best advice but as in any profession, there are those who are only focused on their own bottom line and promote inspectors who may not be completely qualified or may be unethical.  There is no law against that.  Yet.

Do your own due diligence before engaging the services of any inspector.  One home inspector is not the same as another.  California does not license home inspectors, ever.  An inspector is either Certified or fly-by-night.  A true professional carries liability as well as errors and omissions insurance and insurance companies require a signed service agreement for each inspection.  A Certified inspector must be a member-in-good-standing in a national organization which requires annual continuing education. 

I am a seasoned professional, having performed thousands of inspections in Northern California's wine country for the last sixteen years.  The dictionary defines a "professional" as "skilled, proficient, knowledgeable, prepared, talented, competent and experienced,"   in other words a master of his craft. I've taught classes in national conferences for Licensed Home Inspectors in Washington, Oregon and Nevada.

I look at everything I can during an inspection; mechanical and plumbing systems, doors, windows, electrical panels, attics, crawl spaces and the roof. I look for signs of water damage or moisture intrusion as well as missing or falling insulation. And, I look at the construction of the deck and weathering of balconys.  Many are beautiful but not built correctly and are dangerous.

My reputation has been built on professionalism, integrity and the highest qualifications.  I promise you'll get a thorough inspection backed by a 90 day warranty and covered by errors and omissions insurance, ith unmatched customer service and an easy-to-read detailed 60+ page report which covers every room, system and component with lots of pictures.

Don't let anyone mislead you by claiming to be a State Certified or a Licensed and Bonded home inspector because there is no such thing.  Only in California can somebody be a dog catcher on Tuesday and be a home inspector on Wednesday, and I promise you I'm not making this up. 


An inspection, like a diagnosis, is not the place for bargain hunting.  Choosing the cheapest inspection could be the most expensive mistake you'll ever make.   You need an all inclusive, easy to read and understand home inspection report in PDF and Hard Copy, with a 90 day warranty, by an experienced professional.  Less that that is a waste of your money. 

The home purchase is too expensive to risk not knowing what you are buying in order to save a few dollars.  The inspection costs relatively little compared to real estate commissions and down payments, but "the home inspection is the most important part of the real estate transaction" according to Consumer Reports Magazine.

Home repairs can be some of the costliest expenses consumers face.


There are times when cheap is just too expensive.  If an inspector offers to do the inspection for an extremely low fee, but only gives you a verbal report and offers to throw in his hand written notes -- RUN.  Worst case scenario, the house collapses around you in the first rain storm, and you have no legal recourse.  You can't prove a thing.

Identifying potential problems with a home's infrastructure or its major systems before close of escrow can ultimately save thousands of dollars in repair costs.  Current or potential issues that are identified during the home inspection can then be used as a negotiating tool.  A seller might reduce his price, or may even fix the problem before the close.

I won't minimize the extent of  the issues to please someone involved in the transaction whose agenda may be different from yours.  Neither will I exaggerate the extent of the issues in hopes of getting the repair work which is an illegal practice.  The State prohibits home inspectors from repairing properties that they have inspected.   I will report to you exactly what I find .


This law requires the seller to disclose all known issues.  The home inspection report also becomes part of the disclosures but is separate from the seller's form and is not meant to be a substitute for it.  The home inspection may reveal an issue or several issues that had not been disclosed by the seller, or may even be unknown to the seller.  All disclosures are available to anybody interested in the property.

Let Housecheck provide you with the most qualified inspector and the most comprehensive report you can find.   It's the difference between your peace of mind and nagging doubts.


Without photographs, you get less than half the information.  In my experience as a home inspector, sellers have removed etched shower doors, wood carved mantles, brand new water heaters, air conditioners, even doors between the inspection and close of escrow.  And since they replaced them with like items, albeit of lesser value, they see no harm.  What do you think?

Pictures show why a fascia board should be replaced even if you don't know what a fascia board is.  My reports are unmatched in details, in number of pictures and in readability.  View any inspector's sample report online and compare.


You have found a potential property investment in the Northern California Wine Country that will suit your needs and it shows promising growth in equity and profits.  With my experience in inspecting a diverse range of commercial properties, I can supply you with a commercial property condition assessment report that will further reduce the financial risk you are about to undertake.  This report can be used as a tool for negotiations.

The purpose of the Physical Condition Survey was to evaluate the building's structural condition and the performance of the principal building systems.  Choose only a professional commercial inspector who will inspect and report on every area.   Only if destructive discovery is required should a contractor be called in.     READ MORE


Sophisticated buyers as well as first time buyers call me directly to book inspections.  Some are out of state and a few have contacted me from as far away as Japan, Afganistan, and Italy.   My first priority is to provide you, the client, with an honest and complete evaluation of the property you are about to purchase.  Every inch of the property is inspected -- all structural, electrical, air conditioning, heating and plumbing are examined.  I crawl under the house.  I climb into the attic.  I inspect the roof.  I will notify you of any item that has a current or potential issue. 

I do Lake County Home Inspections, Mendocino County Home Inspections, Napa County Home Inspections and Sonoma County Home Inspections.


If you are about to put your home on the market, a pre-listing inspection will put you ahead of the competition.  It will alert you to any immediate issues discovered before potential buyers tour your home.  Then, any issues or repairs can be resolved ahead of time without rushing, which will help the home show better and give you time for repair choices.  This alone can save you a considerable amount of money.  Without a pre-listing inspection, defects can cause unreasonable price adjustment demands from the buyer or even kill the sale and escrow may drag on instead of closing quickly and smoothly.

You will have a beautiful and informative Inspection Report to show the buyers.


Nowhere on this website do we ask you to fill in your contact information.  That ploy is used by some to sell your contact information to advertisers and vendors.  We collect no personal information or data, other than what is required for our insurance and the inspection report.  Also, we do not collect credit card information over the internet.
