Questions to Ask Your Home Inspector or Things Your Home Inspector Won’t Tell You


While the Internet can be useful when searching for some types of information, it should come as no surprise to anyone that it is also rife with misinformation. The term “to google” is, after all, synonymous with to search, and not to research. It is a good search tool and not so good when relied upon as a sole research method.


If you feel that you have done your due diligence by googling what questions to ask your prospective home inspector, think again. Bullshit is prevalent in our society. By bullshit I mean misinformation that is not exactly a lie and certainly not the truth. It is misleading nonsense used to further the writer’s or speaker’s agenda.


If you google “questions to ask your home inspector”, “things your home inspector won’t tell you”, or the like, you’ll be up to your ears in search results from any number of groups with vested interests in selling their positions or products. These will run the gamut from groups like Zillow/Trulia, real estate brokerages and agents, new home builders, mortgage lenders, the bought-and-paid-for main stream media like CNN, Fox News and MSNBC, brain-dead bloggers, forums populated by the over- and under-medicated, etc. ad infinitum. Most of these have simply either found a list of questions and outright plagiarized it or have lightly edited it and called it their own. In other words, the lists you find, by and large, will be merely regurgitated bullshit, and not even the original stuff.


But, enough about the misinformation; how does one find useful information on this subject? Glad you asked. Perhaps a useful way to approach this is to simply make a list of the most common misconceptions floating about in cyberspace, and address each of them head on. For the sake of both brevity and clarity I will handle each of these as they pertain to home inspections within the state of Texas, where I am intimately familiar with the territory and laws. I will also limit the list to the ten questions I most commonly am asked.


Q1: What does your home inspection cover?


A1: Home inspections in the state of Texas are governed by the Texas Real Estate Commission (TREC). While this may appear to be (and certainly is) tantamount to the fox guarding the hen house, it is nevertheless how those folks in the capital of Austin repay us for electing them. The TREC has adopted a set of standards for home inspectors, which includes a detailed list of what must and what must not be inspected. This list can be found at:$ext.ViewTAC?tac_view=5&ti=22&pt=23&ch=535&sch=R&rl=Y


This is the minimum standard for a Texas home inspection. Said differently, it is the worst way a home inspection can be legally performed. While a few highly-qualified inspectors, such as this author, may exceed this standard, most do not. Many are either unwilling to meet, or incapable of meeting this standard.


Q2: How many home inspections have you performed?


A2: While this is essentially a good question, the person asking it will likely have no idea of what a good answer might sound like. The American Society of Home Inspectors requires 250 inspections for its certified members. While that may sound like a lot, it is not even enough to begin to get the drift of inspecting a house. The state of Texas has no such requirement. Once licensed, you are good to go ahead and begin on-the-job training while inspecting houses for unsuspecting buyers. My opinion, based upon 18 years experience in the field, is that, after completing 1000 inspections, an inspector may just begin to think of himself or herself as minimally competent.


Q3: Will you climb on the roof?


A3: Without first seeing the roof, this is not possible to answer. There are many roof surfaces that are not safe to walk on and should not be walked on by anyone but a certified roofing contractor wearing the proper OSHA-required fall protection gear. Certain roof surfaces, such as slate, faux slate, clay tiles, standing-seam metal, old, worn asphalt shingles, etc. are not safe to walk on. Additionally, asphalt roofs should not be walked on during the extreme temperatures we experience during North Texas summers. Most inspectors do not carry or use ladders in excess of 18 feet in height. This may not be sufficient to safely reach the lower roof surface. Even it is, the upper roof surface may be out of safe reach. Most roofs can be properly inspected from a ladder at the eaves and with binoculars from the ground. Roof surfaces with excessive pitches (>6/12) are also unsafe. No inspector in his right mind will risk his life to inspect your roof. It may be interesting to note here that even professional roofing contractors will often not mount a roof to give a replacement estimate. They use .


Q4: Do you use an infrared camera?


A4: This is one is especially exasperating to me. Infrared cameras measure heat differences translated to a digital screen to form a picture. These are sometimes useful during home inspections under the ideal conditions. While they are just another tool in the box, many inexperienced inspectors hard-sell their use to prospective clients because the clients do not fully understand what the cameras are capable of and the inspectors have no other skills to hawk. It makes more sense to ask the inspector if he uses a flashlight, ladder, electrical meter, moisture meter, et al. These tools are more often employed. Let us put this into perspective. Would you consider asking your doctor if he uses a stethoscope, thermometer, blood pressure cuff, MRI machine, etc.?


Q5: How long will the inspection take?


A5: Without seeing the condition of a house it is infeasible to predict with any degree of accuracy how long the inspection will take. On relatively new houses, a range of 1.5 to 2 hours should be reasonable for a highly experienced inspector. It is also possible to spend 3-4 hours on a 2000 s.f. house that is a poster child for materials/systems atrophy and deferred homeowner maintenance, or a flipped (investor’s) house (lipsticked pig).


Q6: How much will it cost?


A6: This is typically the first question asked. It is always an indication to me that the caller has done no research. My fees have always been listed on my website. Most inspectors do not post these so that they can adjust their fees according to time available, house location, etc. Fees vary widely from area to area. They are generally higher in the large metropolitan areas. Generally speaking, the minimum fee for a competent inspection in my area will be somewhere in the range of $450. Those asking less are usually lesser qualified and unable to demand the going rate.


Q7: What type of report do you provide and when will I receive it?


A7: The TREC promulgates the report format for Texas inspectors. This can be seen here:


All inspections performed on substantially completed houses must be reported on this form.


The TREC requires that inspection reports be delivered within 3 days. This is unreasonable. Most inspections happen during a short option period. Inspection reports should be made available on the same day as the inspection. One caveat here is that on-site inspection reports usually indicate that your inspector is a minimalist. There is no reporting system available for portable computers or mobile devices that can substitute for a well-researched and documented report. Any report that is under 60 pages in length is less than fully informative.


Q8: Can I attend the inspection?


A8: This question should never be asked. Assume that you will be attending the inspection. Also assume that you should leave the inspector to perform his observations and draw his conclusions prior to his discussing his findings with you. Inspectors who allow you to “tag along”, and perform a walking tutorial with you while inspecting the house are practicing what is tantamount to texting while driving. Nothing good will come of it.


Q9: Are you familiar with the area in which the house is built?


A9: This assumes that houses are somehow significantly different than others. This is simply not the case. With a few exceptions such as extremely custom modern homes, over-the-top eccentric homes, or extremely old historic homes, all homes are essentially built the same way and of the same materials. Some people like to think that the houses they are considering buying are unique. This is almost always not the case.


Q10: Do you carry professional liability (errors and omissions) insurance?


A10: All licensed inspectors in the state of Texas must carry professional liability insurance as a prerequisite to licensing or license renewal. If you understand what this insurance is you will see that this is a stupid question. Professional liability insurance simply provides the inspector with an attorney should you choose to sue him. You get to hire your own. It provides no benefit for you.


Now, let’s take a peek at some of the questions I would ask, if I were hiring a home inspector. Brace yourself. They will be quite different that the list above.


Q1: Have you ever built any houses? If so, how many? What was your role in the home building process?


Comment 1: A person who has built several houses possesses an intimate knowledge of their materials, systems, structure, function, et al. that cannot be replicated through classroom experience. Driving by a new house under construction or sweeping the floors behind the construction crew in a house being built does not count. Being the general contractor or builder only counts if you actually took an active part in the construction, i.e. sawed wood, hammered nails, etc. Riding around in an oversized. noisy pickup truck and writing checks to subcontractors does not make one a builder.


Q2: What certifications do you hold pertinent to inspecting houses?


Comment 2: A home inspector license is not a certification. It is merely a license to do business. Certifications are available from many organizations. The most relevant are those provided by the International Code Council (ICC). At a minimum, any inspector should hold an R-5 Combination Residential Inspector certification from the ICC. Beyond that there are others available from the Post-Tensioning Institute, the National Fire Protection Association, et al. Note that serving as some type of officer in this or that inspector organization is an affiliation and not a certification. It is an indication that the officer is politically motivated and has way to much time on his hands. It has absolutely no bearing on knowledge of the profession.


Q3: How many real estate agents or brokers refer you on a regular basis?


Comment 3: Most home inspectors rely solely upon referrals from real estate agents and brokers who have a vested interest in finding few if any problems with a house. This unduly influences and severely limits your inspector’s judgment when reporting adverse conditions to you. The answer to this question should be very few or none.


Q4: Are you a sole proprietor or a member of a multi-inspector firm? Are you a franchisee?


Comment 4: Competent professional inspectors find it a challenge to find enough business while attempting to compete with the agent-pleasers (ass-kissers). The ability to procure sufficient business to keep several inspectors employed is one sure sign of an inspector that is tied at the hip with brokers and realtors. Franchisees are usually those who are too inept or shiftless to properly build a business from the ground up. They believe that one can purchase credibility by buying into a franchise scheme.


Q5: Do you carry general liability insurance?


Comment 5: General liability insurance is not required for Texas home inspectors, but is a must in order to protect home sellers and buyers alike.


Q6: How many continuing education hours do you obtain annually?


Comment 6: The TREC requires home inspectors to obtain 16 hours of CEUs each year, see:$ext.TacPage?sl=R&app=9&p_dir=&p_rloc=&p_tloc=&p_ploc=&pg=1&p_tac=&ti=22&pt=23&ch=535&rl=218


Unfortunately, the TREC approves only education vendors who are willing to pay them to be approved. Most of the better and relevant CEU courses available for other professionals such as building inspectors, engineers, architects, and builders are not approved the TREC. Go figure.


Inspectors at the top of their game usually obtain >30 CEU hours annually.

The Safe Home Book

Unskilled and Unaware of It

Dec 11, 13 • News

This is a great article which discusses what I believe to be the case with most home builders in Texas, and perhaps everywhere . . .


A priest, a doctor and an engineer are playing golf. They wind up behind the slowest foursome ever and can’t play through. Frustrated, they send their caddy to see what the holdup is. The caddy returns and lets them know its part of a charity event where they let 2 firefighters who were blinded while saving a couple of kids play a round. The doctors says, “I know experts in this field. I can contact them and donate my time and maybe we can get their sight back”. The priest says, “I will say a special mass for them and take a second collection to help pay for the medical services”. The engineer says, “Why don’t they just have them play at night?” – Submitted by Chris B.

Corrugated Stainless Steel Tubing (CSST) Gas Pipe

Nov 9, 13 • Advice, News, Product Defects

If you have corrugated stainless steel tubing (CSST) installed in your home for gas distribution you are strongly urged to read the following information. I have long been against the idea of installing CSST for gas piping. As with many other building materials that have been developed to decrease costs to the home building industry, the manufacturers of this product seem to have cut too many corners. In the process they have increased the need for precise installation of the product and decreased the safety of homeowners saddled with these, apparently unsafe, installations.

I have monitored the CSST installations over time for performance and have made many changes accordingly to the wording in my inspections reports. However, my low opinion of the product has not changed. In fact, it is now my position that I would not have this product in my own home under any circumstances. I also strongly urge any of my clients with CSST piping in their homes to consider the following information and exercise due diligence regarding this product.

This is the current report verbiage I use. It is subject to change as more information comes to me.

The CSST gas lines do not appear to be properly bonded as required by NEC 250.104(B):

(B) Other Metal Piping. Where installed in or attached to a building or structure, a metal piping system(s), including gas piping, that is likely to become energized shall be bonded to the service equipment enclosure, the grounded conductor at the service, the grounding electrode conductor where of sufficient size, or the one or more grounding electrodes used. The bonding jumper(s) shall be sized in accordance with 250.122, using the rating of the circuit that is likely to energize the piping system(s). The equipment grounding conductor for the circuit that is likely to energize the piping shall be permitted to serve as the bonding means. The points of attachment of the bonding jumper(s) shall be accessible.


The CSST gas lines do not appear to be properly bonded as required by IRC G2411.1.1 (310.1.1) CSST. Corrugated stainless steel tubing (CSST) gas piping systems shall be bonded to the electrical service grounding electrode system. The bonding jumper shall connect to a metallic pipe or fitting between the point of delivery and the first downstream CSST fitting. The bonding jumper shall be not smaller than 6 AWG copper wire or equivalent. Gas piping systems that contain one or more segments of CSST shall be bonded in accordance with this section.


The CSST gas lines do not appear to be properly bonded as required by the National Fuel Gas Code (NFPA 54) 7.13.1 Pipe and Tubing Other than CSST. Each aboveground portion of a gas piping system other than CSST that is likely to become energized shall be electrically continuous and bonded to an effective ground-fault current path. Gas piping, other than CSST, shall be considered to be bonded when it is connected to appliances that are connected to the appliance grounding conductor of the circuit supplying that appliance. AND 7.13.2 CSST. CSST gas piping systems shall be bonded to the electrical service grounding electrode system at the point where the gas service enters the building. The bonding jumper shall not be smaller than 6 AWG copper wire or equivalent.


Additionally, the CSST gas lines do not appear to be bonded as per the manufacturer’s installation instructions. Gastite (and others) recommends that all continuous metallic systems be bonded and grounded. The owner should confirm with a licensed master electrician or electrical engineer that each continuous metallic system in a structure has been bonded and grounded by an electrical professional in accordance with local building codes. This should include, but is not limited to metallic chimney liners, metallic appliance vents, metallic ducting and piping, electrical cables, and structural steel. This is a fire and explosion hazard which must be immediately addressed.


Your are strongly urged to have this system inspected and properly bonded by a licensed master electrician or electrical engineer prior to the end of any time periods associated with the purchase of this home.




The CSST gas piping is subject to damage from nail strikes, electrical wiring shorts, lightning strikes, et al. both during and after construction. The entire system is not accessible for a visual inspection and the presence or absence of damage to this piping cannot be ascertained without destructive forensic examination of the house which is beyond the scope of this inspection.


Even when the flow of leaking gas does not cause a fire or explosion, the possibility of gas poisoning is very real.



Concealed hazards may exist. You are strongly urged to have this system leak tested and thoroughly inspected for condition and proper installation by a licensed master plumber with experience both CSST installation and in gas leak detection, as well as the CSST manufacturer, prior to the end of any time periods associated with the sale or purchase of this home.



Research suggests that, at a minimum, and in addition to proper installation and bonding, the installation of lightning protection systems as per NFPA 780 and gas excessive flow valves (EFVs) may be essential in the presence of CSST, though not the end of due diligence. Finally, replacement of the CSST with threaded steel gas piping may be the only method certain of avoiding the risks involved with this product.


CSST was deemed by a jury to be a defective product. See:



Based upon the evidence currently available, it is this inspector’s opinion that the CSST gas piping may be unsafe even if installed as per the manufacturer’s installation instructions.


You are strongly urged to consider having this system completely replaced with threaded steel gas piping prior to the end of any time periods associated with the purchase of this home and, more importantly, prior to occupying this home. Additionally, the owner of this home should be advised to immediately vacate the home and have the system either made safe (if possible) or replaced with threaded steel piping prior to moving back in.
