Two keys to getting effective results when killing the odor associated with dog urine. One is using a chemical that works and the other is getting the chemical in contact with the urine residue. There are several types of chemicals that are effective in killing this odor. There are good and bad products in each type. Oxidation is one type that works quite well. Clorox bleach is an oxidizing product. It will work well but it has to come in contact with the urine residue for a long enough period of time to do the job. If the dogs have been urinating in the spots you mentioned for months or years then the urine has built up and soaked deep into the concrete. You of course want to make sure each area affected gets cleaned and treated heavily enough to reach the residue and counteract it. I am assuming it is concrete and an unfinished basement. If it is finished with carpet and pad and Sheetrock walls etc. then you have a larger challenge. The principles of odor removal remain the same for the different situations but different materials need to be dealt with individually. The chemical needs to contact the urine. If you are using a enzyme product, it has to come in contact with the residue and stay moist for a long enough period for the enzymes to digest the urine molecules. For concrete I would try Clorox bleach and keep it wet long enough so it can soak deep into the concrete. If necessary use two coats of a pigmented shellac concrete sealer after as much odor as possible has been eliminated.

Hi there!
My husband and I recently bought a house with the contingency the old owners will pay and fix the smell of dog urine from the basement. Apparentley the dog was peeing in a couple of spots for a long time.
Problem is they did have a professional power washing place come out and do the basment a couple days ago. Well I wentr over there to check it yestereday to see if it was gone and I smelled that pluse the wash smell together. Before I even reached the basement! It was being aired out and I’m not sure if it will be completley gone. It sure does’nt smell like it!
They do stll have to fix it, is there any chemical or sealer I should reccomend to the current owners!?

Let me start by saying I am not an expert on roofs. I am aware though that the tar (and tar materials) are used to seal the roof and protect the building from moisture. The gravel is used to protect the tar from the sun deteriorating it and breaking it down. I don’t believe that if the roof is in otherwise good condition that the urine and feces would damage the ability of the tar to seal out moisture. And it certainly would not harm the gravel so that it could not do its function. Yes the roof would be contaminated. Anything the urine and feces comes in contact with would be contaminated. It can be decontaminated by the use of chemicals without replacing the roof. Several type of chemicals will decontaminate urine. Bio/enzymes are the primary organism used to break down sewage in treatment plants. These chemicals have to come in contact with the urine residue to break it down. You would want to clean the roof as completely as possible fist and then treat with a good chemical that will break down the urine residue and not harm the tar. As these chemicals break down the residue they eliminate the odor. When urine leaves the body it is slightly acid (uric acid) and it immediately begins to change. The Uric acid begins to be broken down into ammonia and carbon dioxide. The ammonia is highly alkaline (ph 11+). As the acidic urine reacts with the ammonia that is being created it forms alkaline salt crystals. When dried urine is re moistened it gives off ammonia gas. The odor of ammonia gas is one part of the distinctive odor that helps us to identify and locate urine. The other component of urine’s odor is off-gassing from bacteria that grow abundantly in warm, dark places. I do not know exactly how this process would affect the tar materials on the roof. Thank you for the question.

I have tenants that have allowed their dog to urinate and deficate on a tar and gravel roof to the point that it was covered in dog feces. Other tenants stated this has been happening for 3-4 months every day.
Question:
Can the urine and feces break down the tar roof. If so by what process? One roofer said the roof is contaminated. Another stated that the ammonia and acidity has damaged the roof? Will the urine odor stay in the tar and smell during hot humid days. Both stated that the roof has to be replaced is this true?
