Ok,
please read the trash below, and the complete ignorance of these people actually out doing inspections!
hell, they don't have a clue!
what the hell is laminated vertical hardwood? just start reading, they and, get this, this is from a so call professional service site,,,,gee, I would be ashamed to post at such a site where such people post their work, but, more important and frightening is, the harm they cause people, the complete disregard they have to the consequences their actions, they lack of knowledge, have on people who lived this work, I mean, this shows a complete "me only", disregard for the working people who do the work, no measurements, nothing, they are completely without regard to the consequences to the people who did the work their ignorant report will have.

545 Engineered wood gapping flooringinspections@yahoo.com
I inspected a floor for an upcoming court case. Butt seam gapping 1/16" to almost 1/8" on several boards just in one section. Was gapped like that at the installation. The installers agree they installed it like that, but that it is acceptable. Is there an industry standard for max gapping? Where do I find it if there is?
Replys: From
I have installed for many years and never heard of any acceptable gapping left by an installer. Even NWFA is vague with gap tolerances caused by changes in RH. I am glad I am not that installer, I think he will be at least replacing part of that job. donsgroi@gmail.com

They are abnormal gaps that do not open and close seasonally. NWFA Problems, causes and cures, abnormal gaps, I think page 10. INSPECCPT@AOL.COM

Thanks for the replies. I need to get with NWFA I think. flooringinspections@yahoo.com

Sorry INSPECCPT...this is not abnormal gapping as in panelization or side bonding. These were gaps left by the installers.Is this a nail or glue down product? SLKMCS@COMCAST.NET

Glue down over an on-grade concrete slab. flooringinspections@yahoo.com

They were left at installation I agree, so does the installer. Do they close, No. They shouldn’t be there, I hope you would agree. The question is: the installer said he left them and they were OK. One way to say / explain that they are not OK is to use the Abnormal Gaps from the NWFA. Please read all the info under Gaps, Abnormal. INSPECCPT@AOL.COM

Whoa big fella. Glue down!!! Sliding boards into the adhesive instead of placing them in the adhesive. The adhesive pushes the boards back, leaving a gap at the ends. SLKMCS@COMCAST.NET

Still installation related. If they don’t close during humid season, they are abnormal. NWFA does not mention much more except evaluate from a standing position. Gaps of .016’ are not remarkable from a standing position. Since I can’t see anyway, I use .020" as my guide for unremarkable gaps. insp115@aol.com

Interestingly, there are or were a product that will shrink in the length like that. I had one floor installed as a glue down on wood three x’s doing the same thing each time. floorcovering@cox.net

I have seen it happen when using an inexpensive acrylic (water) based adhesive. The board swells from moisture absorbed from the adhesive, over time it looses that moisture and shrinks to normal size, leaving a gap. rgfloor@sssnet.com

This does not sound like a product issue since the installer admitted to installing with gaps. I think a FEW gaps of up to 1/16" or .060" should be considered acceptable, if they are filled. The manufacturers allow themselves 5%. The installer should not have to deliver 100% perfect. Stain and putty are a normal part of any hardwood floor installation. djhoran@comcast.net

540 Finger-jointed solid hardwood flooringinspections@yahoo.com
I didn’t even know this existed until a few days ago!!?? Not really "solid" I guess. What would cause 20% of the installed boards to start splitting along the "joint" lines, starting at the ends? This is nail down over wood subfloor in a new construction home; the wood is really wet-measuring 14% to 16%.

What did the substrate (that it was attached to)meter for moisture content? Do you have EMC?? floorcovering@cox.net
10/08/09
I was unable to measure the moisture in the substrate which is typical. Short of removing flooring, how do you measure moisture in the subfloor? What does EMC mean? flooringinspections@yahoo.com
10/09/09
The flooring is a four-strip finger jointed material. It had a higher moisture when installed than does now (as measured by gapping and 10 across width). Is there anything the installer did or site condtions that would cause the splitting, or is it manufacturer related-perhaps from moisture imbalance between joined section, causing stress as they dry down to normal moisture levels? flooringinspections@yahoo.com
10/09/09
Maybe to your questions...but first, you must review EMC or Equal Moisture Content....take moisture readings of the baseboard, joists from under the home, or any common wood cloose to the or attached to the flooring. What did an extra of wood meter? Was the material wrapped in plastic in the box, was it opened and material acclimated? Improper nailing? Measurement of the tongue and groove to standard? I take it that spitting is on the tongue only? e-mail me floorcovering@cox.net
10/09/09
My mistake; I guess this is called vertical laminated solid hardwood. The splitting is along the glue lines between glued sections/strips. As far as the moisture questions-can improper acclimation cause splitting along the glue lines?? How is that possible? Whether the flooring is first acclimated properly in unsealed cartons, or is nailed down and then acclimates to the home environment, what difference would that make on splitting at the glue lines? The tongues have no splitting. flooringinspections@yahoo.com

I would be more concerned with if the home was enclosed when the floor went down. The cause of the cracks at the joints is the high moisture. No way that it left the mill at that high numbers. This has to be site or storage related to cause such a high moisture content. donsgroi@gmail.com
10/09/09
Okay, but I’ve seen a number of wood floors with similar high moisture readings, especially where one board is 12% and the adjacent one is 15%, and the overall average was maybe 13 or 14%. And this has been increasing for me over the last year or so. I think some of the manufacturers are not taking the time to dry down the wood properly before shipping. flooringinspections@yahoo.com
10/09/09
^^^Did you get these readings from uninstalled or installed planks. You have no way to verify what they were dried at since you were not there. They can pick up moisture once they leave the manufacturer from any number of places. You can measure substrate if it is wood if you have a hammer probe. If not, pin it, drive nails into the pin holes until you feel them go into the sub floor & pin the nails. sjohnston1@triad.rr.com
