As houses sit for months, and in the case of this house over a year, conditions can develop that buyers might not consider. This one photo is reason enough to get a home inspection! This buyer told me he had been to (and since there was a combo box on the door INSIDE) the house many times. He had not noticed a lot of what I had on my extensive report, but certainly had not noticed this.

Unfortunately it was a very cloudy and dark day, so this picture may not do this circumstance justice.
This is the gas water heater vent.
IT HAS BECOME A BIRD CONDO!
At the lower center hole a little one is actually looking out, but not too visible!
This is what I was reminded of when I saw it.
It's a virtual apartment building for birds!
There was grass or a little head peaking out of all eight holes the water heater vent had to offer.
These birds are very clever little fellows. They know that nobody is living in the home.
Finding this convenient place to locate their nests, probably last spring, they moved in and have raised their families there ever since!
BUT WHILE THIS LOOKS CUTE, IT IS AN EXTREMELY DANGEROUS THING FOR A NEW HOMEOWNER!!
I mentioned that the buyer had not noticed this. What if he had decided NOT to have a home inspection? He would have moved in. That water heater is located in an attic space, right beside the upstairs bedroom in this cape cod home! They would have lit the pilot light and began heating the tank.
This flue goes down vertically about 2' below the roof, where it turns at a 45 degree angle for about 3' and then to a slight incline for another 4' or so.
Birds would have been killed by the CO produced by the heater. As they died, they may have fallen into this vent, partially or totally clogging it!
As that poisonous exhaust was discharged it would have been blocked, forcing CO into the home, and that bedroom.
NEED I ASK YOU THE RESULT?
The simple removal of bird nests will prevent all of this, and it was discovered during a home inspection.
My recommendation: Get a home inspection before you buy! It may save a life, or two, or more. Maybe even yours!

Jay ~ Terrific information and just one more reason to have a Home Inspection. I have one coming up on a contract which is being negotiated -- just wondering what the cost would be. I mean, we can work around your schedule -- besides, it's a nice little drive??? LOL Happy New Year to you and your family! Bet that wee one is growing like a weed! Best.
Jay, I had bees completely plug my b-vent before---I had a river of condensate dumping into the basement :)
Fish gotta swim, birds gotta nest, we gotta evict. :)
Btw them nuts are GOOD!
I found a similar situation at my sister's house when she bought it - we couldn't figure out why the water heater was backdrafting, so we took the vent connector apart and found a dead bird blocking it. This stuff really happens.
Don - lots of things inhabit houses that we often don't imagine, and some things in huge numbers!
Ed - I have gotten to "empty" houses only to find people living in them!
John - some people might even see that grass hanging out of the flue and not understand that it is a problem!
Kathryn - dead squirrels are not uncommon. I have had a couple of those in my face!
Steve - I have seen them in chimneys, but never in such a flue.
Jay - I don't know if I was able to impress upon these people just how dangerous this situation was!
Tish - you'd need me for a day a night and a half another day! That might get pricey...
I am going to see the Wee One second weekend in January.
Charlie - and wasp nests which completely prevent the bath vent flap from opening! Or is that what you meant?
"If the flue don't fit, you must acquit!" Is that what you mean Jim?
Is that cash yew eatin'?
Reubs - say it ain't so! Actually I bet it happens a lot! I wonder about the newer PVC high efficiency flues which are not screened in any way. What stops birds from getting in there and dying?
Jay - You paint a very EFFECTIVE and colorful illustration for my getting my chimney inspected this coming week. I haven't built a fire yet this winter.
This is a flue Myrl, but chimneys can be just as dangerous and just as important to keep clean.
Good question about the PVC tubes. I've actually never heard of that happening.
Well, Reubs, they aren't supposed to be screened because of the possibility of ice build up. But what a bird invitation!
You could put one of those big plastic owls on top!
SO MANY reasons why having a home inspection is vital! Another great post Jay! Happy New Year!
There really are Barbara-Jo, and many unpredictable. Thanks for the reblog!
Jay, that could have been one huge disgusting mess for the birds, and a disaster for the humans! Glad they hired you. I'm sure they are, too! Happy New Year!
Thanks Pat, and happy, happy to you too!
Glad you caught this one. You do have an interesting job to say the least.
Thanks Anne. And we inspectors will never be able to say we've seen it all!
Wow Jay, something I'm sure not many of us would have noticed this. Very dangerous situation could have developed.
Jay, good post. Scary.
My dryer was not working well for awhile - we decided to get a new one. When we pulled it out to see if we needed a new connection or hose in the back, we found that it was disconnected. No wonder my laundry room was so moist and steamy.
Anyway - the dryer vents to a wall outside the garage, high up, with 2" slats, like little mini blinds. I went out and looked at it - yep! You guessed it - with no air coming from the dryer, it was a perfect place for birds. We took off the cover and there was the start of a nest in there, and bird poop on the sidewalk below. After we finished cleaning it up, I wished I had taken a picture of our little guest house in the works.
Lyn - some people may have noticed it without thinking it could be an issue. What's inside the flue now may already be one! This water heater is not operating, so perhaps something is blocking it and we don't know.
Virginia - dryer vents are a huge problem, either from lint build up or bird nests. Something like 40,000 fires every year from blockages! Pay attention and you will be okay.
