I rebuilt a house in the area a decade or so ago that had cracks in the walls that I later discovered had a 6 foot diameter bee hive in it.

Their growth upwards will slow down around 35 to 40 feet and then their girth or diameter will start to thicken. 

A 6ft diameter, healthy looking oak just fell from my neighbor's backyard onto my rental property. 

We are working on finding the leak but in the meantime this tenant (who is needy and has been otherwise annoying) is making a big deal about these small stains that are about 4” inches diameter.

The benefit is it can be sculpted to match the profile of difficult to find trim and can fix rotten patches of wood siding (up to a few inches in diameter) without pulling anything off the house.

Source custom-cut 1.5" minimum diameter rods that are continuous length (not the expandable ones as there is usually a gap in the metal that fabric can get caught on).

A typical sink drain is made of 1-1/4" diameter pipe.

There are two good sized spots, maybe about 10 inches in diameter and several smaller spotted areas.  

I mean LARGE, like some were 4' x 8', spots were 1/4" diameter!

It's made out of wire inside a small diameter pvc pipe inside a larger diameter pvc pipe.
