Inspection Report Reviews
We are reviewing reports submitted to us by our associates. This is not being done to embarrass anyone. Our goal is to help make our trade better.
Bosch GSL2 is a great tool, if used correctly.
I wish I had one.
The claim was the vinyl planks warped, cupped, we like to use the word "warped" but, cupping, concave or convex bowing,
When using the GSL2, it can find high and low spots on the surface of the substrate it is placed. Again, a great tool that saves time, which means, saves money.
The inspector placed it on top of the warped vinyl planks, which means, he was not measuring substrate irregularities but he was measuring the contours of the flooring, the warped, cupped, bowing, whatever term you use, vinyl planks and not the substrate.
His report stated the substrate, which he could not measure without taking up the planks, did not meet the manufacturer's tolerance for flatness and that caused the planks to warp. The substrate does not affect manufacturing issues. Vinyl planks warp where the substrate complies, and it is not in compliance.
If that was true, it would only warp over the non-flat and smooth areas and not warp on the flat and smooth areas of the installation.
In all installations, there are areas that are flat and smooth when there are areas that are not flat and smooth.
Please, apply simple logic to evaluations.
When the vinyl planks are warped, you can't place a straight edge on top of them to measure substrate flatness. If you do, you are measuring the raised edges of the vinyl planks. Again, not the flatness of the substrate.
The same is true with the GSL2.
Can a non-flat and smooth substrate cause vinyl planks to cup?
No, the fault is within the product.
The layers of the planks, the components, the same as engineered wood, must be in equilibrium in their shrink and swell characteristics, and moisture absorption; or they will warp out of a flat and smooth shape, planar stability.
This is especially true at the time the planks are laminated together.
It is called, Balanced Construction.
Balanced construction is recommended as a viable means to either prevent or decrease warpage and delamination in a laminated flooring product.
Click on Mr. Migliore name to read the articles.
Definition: Planar stability is the ability of the material to lay flat and level, that is, not curl up on the ends or the sides. When the material is installed on the floor it should stay there without lifting up at all.
What is sad is that the report was accepted and the homeowner's claim denied.
Claims analysts process the inspection reports. Over time, they learn a lot about flooring but they depend upon the inspectors to be knowledgable, and have the ability to apply logical reasoning to a problem, and the "smarts" to solve the issue and how to inspect complaints for each job.
Claims analysts with just a few years experience, will have learedn a lot but they still depend upon the inspector's report to be factual.
Inspectors should know how to correctly use their tools for accurate reports.
They must know the products they inspect. This inspector did not know how to use his tools or the product. He should not be an inspector.
Who was harmed by this report? The homeowner. You cannot measure substrate flatness with the meter placed on the surface of a warped floor.

The inspector wrote in his report the cabinets were installed on top of the vinyl planks.
He wrote the dimensional lumber used to frame swelled pushing against the planks causing them to "cup"
The second inspection found no buckling, the planks are warped. .
Ok, let us think about this one. if that was true, the planks gained moisture swelling against the vinyl planks, there would be buckling.
Keep thinking about this one, dimensional lumber is usually 12% to 14% moisture content, pressure treated 15% to 19%.
What is the moisture content range for wood flooring, and other wood products in a home exposed to ambient environmental conditions? 6% to 9% average.
Wood is hygroscopic, which means, it either absorbs or desorbs moisture depending upon the level of relative humidity in the environment it is located.,
The region of this inspection? 7-9% average moisture content of wood in a home..
So, the wood used, exposed to the average ambient conditions in the home, gained moisture?
Nope, it would have lost moisture shrinking pulling apart or away from the vinyl planks, and not pushing against them, to reach an equilibrium between 6% to 9%.
The inspector did not do moisture content measurements on the subfloor or other wood products in the home and none on the cabinets framing lumber.
This report was accepted by the manufacturer.
The claim was denied.
The denied claim was based upon a faulty inspection report. The inspector appears not to know the basics of wood science and no knowledge of dimensional lumber or the product. .
Who was harmed? The homeowner.
If the vinyl planks are not buckling off the substrate, and are warped, it is defective.
A homeowner called from south eastern Tennessee asking for help.
There had been a leak in the house. After the remediation, new vinyl planks flooring was installed in many areas. The planks cupped where the leak happened and no where else.
Instead of asking the right questions, and doing an actual inspection, the inspector saw two large dogs and found dog urine on the vinyl planks in an area that was not cupping.
The report stated the pet urine, found not on cupped planks but on the flat and smooth vinyl planks, caused the planks to cup in the other area where the leak happened.
The answer was simple, the subfloor wood panels, OSB or Plywood, had not been dried sufficiently by the remediation company and then the vinyl planks cupped after gaining moisture from the wood.
Dog urine did not cause the planks to warp or cup. No dog urine was found on the cupped planks.
Any thinking person should see the inconsistency in this report but it was accepted by the manufacturer.
Using either a Delmhorst or Tramex moisture encounter meter would have found the truth, but was not used.
If moisture measurements had been done, the "so called inspector" would have measured moisture differentials between the non-cupped and cupped sections.
No pH tests.
No moisture measurements.
This was a walk-in and walk-out inspection to find no manufacturing defects.
This report was accepted and claim denied. Claim denied was the right decision because there were no manufacturing defects but was based upon a bad report.
Who was harmed?
The homeowner was blamed, when he should not have been.
There was actual harm done to the homeowner based upon a bad report
The puppies should have bitten the inspector while he was there.
Dog urine does not cause vinyl planks to cup.
A retailer on the West Coast asked for the warranty in effect the year he bought the flooring, sold and installed it, 2019.
The claims analyst told him they do not keep old warranties and he would have to go by the new warranty, not the one from 2019.
The thing is, the installation instructions and warranty changed after he bought, sold and installed it. Using the new installation instructions and warranty, his claim was denied.
Legally, only the installation instructions and warranty in effect at the time of sale can be used to evaluate a claim.
An inspection report used the current installation standards and warranty. Either the inspector was dishonest in his bias to the manufacturer or ignorant and should not have been inspecting flooring.
Warranties and installation instruction have to be kept for years, and years.
This claim was originally denied.
Cracked ceramic tile inspection cracked and ledged tiles.
A ceramic tile inspection report stated the tiles had gained moisture, water, when the kitchen and hallway were flooded from a broken water pipe and had swollen that caused them to crack and develop "ledging".
The subfloor, plywood, and joists were dried using fans and exhaust fans in the crawl space. The tiles were not replaced.
The report did not state moisture content measurements of the plywood substrate or wood joists.
The report did not describe the condition of, or shape of, the joists.
The report did not state what type of type the subfloor was.
Here is some important information that should have been in the report but was not.
It is information that was not taught in his "advance" ceramic tile class.
There are water absorption classifications as defined by the American Society for Testing and Materials (ASTM) to be aware of.
Impervious: Tile with water absorption of 0.5 percent or less.
Vitreous: Tile with water absorption of 0.5 percent to 3 percent.
Semi Vitreous: Tile with water absorption of 3 percent to 7 percent.
Non Vitreous: Tile with water absorption in excess of 7 percent.
The inspector did not identify what type of tiles they were or water absorption percentage.
The tiles were impervious porcelain 0.5%
He did not look at the joists. If he had, he would have seen the joists had developed a significant creep or sag under the weight load after the leak
How much weight was on the subfloor before and after it all got wet? 20-22 pounds per square foot.
The inspector claimed to be a certified ceramic tile inspector after taking a 1.5 day class, where there was no teaching about ASTM or ANSI standards were taught or even mention.
Claim was denied for manufacturing defects, as it should have been, but again, the wrong reasons based upon a bad report.
What happens to wood when it gets wet?
This will be covered in our Spring Advance Wood Class.
The homeowner had to hire a real ceramic tile inspector and then he got satisfaction and resolution of his problem.
He was harmed but he got resolution of his claim but not before long days of conflict, a bad reputation developed and a ruined business relationships. Harm was done.
Truly, someone “CERTIFIED” a ceramic tile inspector in a 1.5 day class? And not even an ASTM / ANSI book given out?
No experience with tile flooring but, thinks he can learn it all in 1.5 days.
This is harm to all who work in the ceramic tile industry, from the mills to the retailers and contractors to the consumers.
As Penny Sures says, UNBELIEVABLE!
Cracked ceramic tile
The complaint was extremely small gaps between 4" X .75" planks, and also larger gaps between sections of the planks approximately 4' apart.
The house was a remodel. New flooring.
HAVC was operating at the time of the installation.
The wood was acclimated.
The inspector did no span measurements of the planks or individual width sizes.
There were no distance measurements between the repeating large gaps every four feet apart apart.
This is the size of the OSB subfloor panels the wood is installed on.
He also, did not look into the basement or he would have seen a large dehumidifier in the basement that the homeowner installed after the installation was completed.
More? No moisture content measurement because he said, he was unable to stick his pin meter into the wood flooring.
Yep, actually put that in his report and blamed the installer / contractor. He justified this faulty report in his conclusion by stating he was an "advanced inspector". Nuff said.
The so called advance inspector did not know how to use his Big Box Cheap Meter.
Do you know the answer to what happened? Another class in our Wood Science class coming later this year. (Yep, a teaser)
Because the homeowner believed the inspector and spent large amounts of money hiring a lawyer, and then the remodeling contractor had to hire a lawyer.
Everybody ended up harmed.
The inspector did not know the basics of wood science, building science, the nature of the products used, in fact, he knew nothing other than he had paid money to attend a class taught by a manufacturer and then given a certification that then he was an "advance inspectors".
This is bad for everyone, Everyone is harmed by such inspectors.
Thanks to the Peer Reviewed Inspector, John Paul Viveiros
In the photographs, the inspector saw the vinyl tiles were warped.
The first photograph to start watching is the whole vinyl tile on the floor with the raised curled edges.
He pulled loose and peel back the vinyl wear-layer from the core underneath the surface.
He then set the tile in normal environmental conditions. 68f to 72f.
Within 12 hours, the vinyl surface had shrank. He measured the amount of shrinkage.
The core underneath the surface that had been pulled loose had flatten, no longer curled upward.
Anyone who has worked with vinyl knows it has what is called a tensile memory. It tends to shrink.
If the core material it is bonded and pressed onto, laminated together, does not have the "strength" to prevent the vinyl from shrinking, then the vinyl, as it shrinks, will pull the core upward.
As can be seen in the photographs, once the pressure of the shrinking vinyl surface is removed, the core flattens.
This is what happens when the product is not "balanced".
This is a manufacturing concern, issue, defect.
