When was the last time you looked at yours?

     Grey water.

     Sounds appetizing doesn’t it?  Water that drains from your kitchen sinks, bathroom sinks, laundry sink, dishwasher, and clothes washer is considered “grey water.”  In other words----not quite as nasty as the "brown water" that drains from toilets.

     A leak from either can be nasty but not quite as bad as leaks from toilet drains can be.  If you have to pick a type to leak for 30 years into your crawl space, you would want to pick grey water.  For example a leak from a kitchen sink drain.  The resultant crud that would end up in the crawl space wouldn’t be quite as bad as it would be if the leak was from a toilet.

     Even a leak from the kitchen sink, like in the picture below, can create quite a mess in a crawl space.

what is all that grey gunk?

     This joint had likely been leaking for 30 years.  This was the age of the building and the access opening had been floored over with hardwood.  The amount of soil erosion under the leak was consistent with the pipe leaking for a very long time-----plus it did not smell like roses down there.

     Crawl spaces should be professionally inspected at least every two years-----when was the last time you looked at yours?

It’s just a stain!
Home inspectors will often make comments about conditions that have happened in the past but are not present at the time of inspection. We will note a stain on the ceiling and state that it was not wet at the time of inspection (or that… more
Neighbors are only too happy to help.

The tide is turning----and I am on my way!
Getting to work can be difficult at times. Traffic can be a bear. The weather can be a problem. I spent a lot of winters in the Syracuse and Oswego, New York areas so I know a lot about driving in the winter. Almost always,… more
Mom----why is the glass all over the stairs?
I don’t get my panties all wadded up over broken seals in windows or skylights typically. Broken seals don’t “drastically” affect the thermal performance of the unit----certainly the cost of replacement will NEVER pay for itself in… more
Why are my plumbing vents flashed with Latte cups?
One of my pet peeves as a home inspector is the use of inadequate flashings for pipes that penetrate the roofing materials. My opinion is that the flashings chosen should be designed to last as long as the roof is projected to last----if… more

What is your ape index?
Do you have a positive or negative ape index? I guess before you answer that question it might be a good idea to know what an ape index is-----otherwise who knows where your mind might go. If you are or were a sport climber… more
Well, how does that float your boat?
As a Licensed Structural Pest Inspector, the inspection of House Boats for conditions conducive to wood destroying organisms almost seems like an oxymoron. And yet the few that I have inspected, or worked on, have had no more issues with… more
