Horrible odor in bedroom
For the past several weeks, I have a horrible stale musty odor in my master bedroom. I have a chihuahua that had many repeated "accidents" on the wood floor -- raising his leg and peeing at the corner of the closet door. He would do this during the night so it was often not noticed until it had dried in the morning. Trouble is, there was no quarter round installed after the floor was installed several years ago. It isn't very noticeable so I never bothered to have the quarter round put down. But of course that allowed the urine to seep down into the side of the edge of the wood floor and down between the baseboard and into the subfloor.
I have poured so much "Nature's Miracle", vinegar, and other cleaning products in the area--the dog has been almost 100% cured of his accidents (making him sleep in his crate was a huge step in the right direction). For the most part I thought I had pretty much eradicated the odor. The wood is actually slightly discolored in the area from the urine and probably more so from all the cleaning products. I even removed the piece of baseboard and painted the subfloor between the wall and the gap where there is no quarter round with Kilz to seal in the smell.
For the past several months the smell has been pretty much gone except on really rainy days. But out of nowhere, the room smells like the dog has peed everywhere. It smells like there are puddles that have never been cleaned. The odor pervades the room with a stale musty smell that is horrible. The thing is the dog has not had an accident in months and I checked everywhere in the room and cannot find any spots where he might have gone. I have cleaned and mopped the entire floor. I have gotten on my hands and knees and smelled everywhere and can't pinpoint where its coming from. When I smell the spot where all the accidents occured, it really doesn't seem like it's coming from there. It seems like the odor just lingers in the center of the room. I even removed the mattress and box spring to see if something had got under the bed.
The logical choice would be to say its the old urine spots, but why would it come back so strong after such a long time with no accidents? Is it possible the smell is coming through the A/C ducts? This is the only room that smells this way.
Please I would greatly appreciate any suggestions! I am thinking about ripping out and replacing the wood floor but I'm not even sure that is the source of the odor!
