Just adding thickness won't block the entire listening frequency spectrum, surface textures can help too, look to studio construction, it should explain the frequency ranges and standards as well as textures in design.....find an audio engineer.Why not ask the neighbor not to put the dog along that wall.

However, when we were looking, Realtors told us the PM fees could be as high as 30%, so I don't think 20% is out of line on the surface of it.

At that point, we will have fresh paint on every surface in the home, fresh carpet in all rooms, all new light fixtures and switches/'bling' oiled bronze switch plates...

Tax returns and loss of income will surface.

It sure is nice to start that cash flow on day 0.However, the negative to this is that I personally did not do or oversee the work--and it's always been (in my experience so far) barely average to subpar once you start to scratch below the surface.

To dig deeper, you'll generally need to be qualified to get past the gate keepers, but there should be enough in the public domain to skim the surface. :)

The air temperature and surface can't be below 50 degrees otherwise it won't dry.

With those books you read, they are great on the surface, but there are many MANY nuances only experience teaches/shows, so do ask around.And thank you for your service!

There is growing literature where the environment in a home, post smoker(s) is examined and which is finding that the nicotine and other toxins, when painted over, eventually make their way to the surface again.

I see another set that I believe is going to surface in the not too distant future.
