"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

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.

Installing a mitigation system reduces radon levels, which can cause lung cancer, providing peace of mind and long-term health benefits. It can also increase your home’s value, as many buyers prefer properties with radon safety measures in place. The investment is relatively low compared to the potential health risks associated with prolonged radon exposure.

A homeowner can install a radon mitigation system on their own. But it’s a challenging DIY that requires a lot of knowledge about radon mitigation as well as familiarity with local regulations. You do not want to risk an improper installation that leaves the system unable to detect radon or gives it a shortened life span. Relying on a professional is the surest way to guarantee a successful installation.

The average radon mitigation system uses about 876 kWh of electricity per year, although the exact amount of electricity used will vary depending on the size of the radon fan. Once the system is installed, the annual increase to your energy bill could range from $30 to $300 per year, again depending on the size of the fan.

The natural breakdown of uranium in soil, rock, and water can cause radon to appear in a home. The gas seeps into homes through cracks in foundations, walls, or floors, as well as through gaps around pipes or construction joints. Radon levels are influenced by soil composition, building materials, and ventilation. Poorly sealed or airtight homes can trap radon, allowing it to accumulate.
