CSST bonding

Could you please send me anything that you have that would explain the need to have CSST bonded? I am in the process of arguing with a builder who says that because of the vinyl coating on the CSST it does not need to be bonded. That goes against what I always understood from you. This is on my listing in Waukesha (only 3 years old) that had the CSST called out on the buyer's report. The seller's builder is saying that it's not necessary. I thought I had a good explanation of why this isn't up to par, but I can't find it.

"Scott, ​

Thank you for the incredible report. This will be our home maintenance bible for quite a while. It definitely helps us feel that we know exactly what we are purchasing with this house. Based on our interaction today, my experience with your office, and this report, I can see why you are so highly recommended and successful.

Do radon levels change over the years?

I purchased my house four years ago and had a radon test that was under 4.0. We are now selling and the inspector tested the radon and it is at 6.6. How can this be?

Hi Tonya,

Do I test for radon in a slab home?

Are homes with concrete slab foundations less likely to have high radon levels?

Roof Discoloration from Algae

The following information is from a technical bulletin produced by the Asphalt Roofing Manufactures Assocation.

For many years, roof discoloration caused by algae has been observed throughout the United States and Canada. The discoloration usually has a brown to black appearance, and may be mistaken for fungus growth, soot, dirt, moss, or tree droppings.

Pull down ladder in a fire ceiling

Our garage has a drop-down ladder in the ceiling, providing access to a storage area in the attic. When we bought the house, our home inspector informed us that this was a violation of the firewall between the garage and the house. Is there a reasonable way to correct this problem and still retain storage access from the garage? —Gene

Dear Gene,

Attic Access in a firewall

My home is about 25 years old, and the attached garage is separated from the house with a brick wall and a steel entry door. However, the brick wall does not extend to the roofline, leaving the garage open to the house attic. The home inspector never mentioned this condition when I bought the property and it was apparently approved by the city inspector when the house was built. I am concerned about this incomplete partition wall and would like to know if it is a fire safety violation. - Jack
