I had a request to install two different Rh probes.

I had a request to install two different Rh probes.
I don't know why, but when a large flooring installer asked for Rh testing on a project, I was asked to use Tramex probes and Wagner Rapid Rh probes. Of course I obliged, it's in my job description! Tongue

Luckily for me I had some Tramex probes and checking calibration went well (when they go out of calibration they have to be replaced at $165 a pop! ) so I had probes to use. As my probes fall out of calibration I am not buying new ones!!! The problem with testing using Tramex is the TIME it takes!!! Sad You have to leave the probe in the hole at least an hour before you can read it. So testing 10 holes with 3 probes means the testing will take 4 hours minimum, then you have to watch for drift on the readout for 5 minutes, and I also try to plan my locations out because if the sun is shining in the room and it hits the aluminum Tramex probe, it will throw the reading way off. If I have to test in a sunny room, I set up a sun block and then monitor it so someone doesn't move it.

I quoted $60 to provide Rh testing using the Wagner's and $40 per hole for the Tramex, and the sub was shocked when I quoted follow up testing to be $5 for the Wagner and $30 for the Tramex (this includes drive time and reporting). This sub wanted to track the floor over several months and I explained the Wagner Rapid Rh I can easily read in a matter of seconds (in fact I sometimes leave a reader for the super to read them) whereas the Tramex I can only read 3 holes in 65 - 70 minutes using all three probes. Someone wanted both probes though, so the decision was still to install both.

Well to make a long story short (to late huh? Tongue ) the first readings I took with the Tramex matched the Wagners and the sub cancelled all further Tramex readings. Big Grin I liked that idea, no fighting with sun and no standing guard over three probes in different rooms running back and forth trying to protect them.

The reading matched? What kind of sleeve if there is one goes with that Tramex?

They use a full depth sleeve with a rubber stopper on the top.

Is that $60 for 3 rapid rh holes or just one? If it's for 3 I am hiring you!Big Grin

$60 per hole is a steal and you know it! I see some guys charging well over $100. If it's a bigger job a guy can afford to go $60 a hole. Like 25 probes minimum. Or if you're like me and just practically give stuff away.

But I met some players in the business, helped out a regular contractor of mine, and in the end got a decent job from it. Wink

Oops, well sorry.

If I have to do 3 holes, which is kind of minimum, and the job is 2000 miles away so I have to take a plane, then I charge for the flight, expenses, hotel and the cost of the probes, along with another flight etc to read the probes 72 hours later, so in some cases I charge $900 per probe. Big Grin

But how much are you making per hour?

Edit: Did I say something bad? Sorry, I figured since the word got typed the sites censor didn't mind. Just a figure of construction lingo. Cool

You'll be stripped of your Guru status Mr. Potty Mouth... LMAO!!!
I can't even remember what you said. A lot of these forums have warning status indicators and tallies of infractions... Gotta keep you construction boys clean.

How much am I making per hour?..... Hmmm... Well right now I'm billing my guys at $60 an hour. Most jobs we bid, but if I am asked to do some extras, I just figure $60 an hour and then charge for machine time based on the tools we use.

Some weeks I make pretty good profit! Big Grin
Some weeks I lost my tail.... Sad
In the end I hope my wins outnumber my losses and every customer is ecstatic! (that's part of my job description you know)
I take the bad with the good, and if I screw up I pay for it just like I expect to get paid when I do things right.

But to figure Rh testing, I try to figure $60 an hour, I add some for the job report, and try to cover my travel expenses. My business is not installing Rh tests, my business is consulting on wet slabs and flooring failures and then installing moisture mitigation systems. If someone just wants testing done, they either know me well, or they soon will. Tongue

Big Grin Musta been the wine talking.


Does 60 bucks include the time you go around figuring out where to place the sensors and mapping them out and waiting the instructed time to read them? Sounds kinda low.

I know, I know you prostitue them out to get the remediation. Sad Setting a bad precident you are. Is prostitute a cleaner word? Is this gonna be my second strike?Big Grin
