"The insurance money was in the bank in which the loan for the house is from.
My banker wanted a bid and a waiver of lien to be given them BUT John Fowler never produced one to me.
My banker also wanted receipts from Fowler and I told Mr Fowler that I needed the waiver signed and all receipts as he buys
any items.  Mr Fowler say OK, but he never signed till the very end and I had to hold money till he did signed it.
As for the receipts, never did he give me any but at the end, he took all at once to the bank to give to them.  I decided to go to the bank and get copies of the receipts but beat him there and so I got a copy plus he got a copy and the bank got the originals.
My banker was great on this as we went over the receipts and I went home and did it again, more then once.
What got me most of all was he kept asking my insurance adjustor what kind of money I was going to get and using my name saying I also wanted to know.  To me, he had no reason to do this, ever.
Fowler charged my insurance for saws of $200.00 and other items plus an account that didn't have any thing to do with me and had no proof that it was plus another account.  All and all, Fowler charged my insurance to pay him $2,588.17.  His bonus money and since he broke our hand shake, didn't get anymore bonus money.
Trust, no way, the work, fine but I had to hold back more money as he didn't finish a few little things that needed to get done and so I had to hold that money just to get his men back.
He said he hates lairs!   He needs to read a dictionary on what a liar is.   I will never use him again for anything and he asked me to allow him to inspect all my rentals as he does that to.  NOPE, can't trust him, hand shake or not, can't trust him.

Radon Detection and Reduction questions, answered by experts

No level of radon is technically safe, but since it is present everywhere, complete avoidance is impossible. The average radon level in homes across the United States is 1.3 picocuries per liter (pCi/L). The Environmental Protection Agency (EPA) recommends taking preventative measures if your home's radon levels are between 2 and 4 pCi/L or higher.

Your radon fan needs to operate 24/7 to be effective. The only time the fan isn't operating is during its replacement. Radon levels in the home can increase within hours if the fan stops working or something obstructs the stack vent. Fortunately, radon systems require no downtime maintenance between fan changes.

Radon enters your home when warm air begins to rise and exits through the roof, creating a vacuum that pulls cooler air from under the foundation. Part of that air is radon, which is an invisible, odorless gas that develops naturally when radioactive particles are deep within the ground. Those particles usually come from decaying matter in soil and rocks.

The lifespan of a radon mitigation system depends on the type of system and its maintenance. With proper care, a system can last for many decades. Passive systems tend to last longer as they have fewer components that require replacement. Active systems, which have more moving parts like fans, generally have a shorter lifespan. For instance, water filtration devices and active pressurization systems require more frequent maintenance. While the system as a whole is durable, the radon fan in an active system typically has a lifespan of 5 to 10 years and will need to be replaced. As long as the fan is working, the mitigation system should function correctly.

Mitigation reduces radon levels, protecting your health and complying with safety standards.
