Yes, and it happens a lot. Carpet fibers can’t hold much liquid, so urine runs down through the pile, into the backing, and spreads out in the pad underneath. The pad soaks it up like a sponge.
That’s why a small spot on top can mean a much bigger wet area underneath. It’s also why the smell keeps coming back after you’ve cleaned the spot you can see.
How does urine get into the padding?
Picture the layers. On top is the carpet pile. Below that are the backing layers that hold the carpet together. Below those is the pad, and under the pad is the subfloor.
Urine moves down through each layer, spreading sideways as it goes. A cat or a big dog going in the same corner over and over keeps adding to it. Over time, the pad holds layer after layer of old accidents, and some can reach the subfloor.
How can you tell if urine reached the pad?
Some common signs:
- The smell gets stronger on humid days, after vacuuming, or after you spot clean.
- Yellow or brown rings come back after you’ve cleaned them.
- Your pet keeps going back to the same spot.
- The carpet feels stiff, or the smell is strongest near walls and corners.
The smell coming back on humid days is a big clue. When urine dries, it leaves salts behind that pull moisture out of the air. Nashville summers give them plenty to work with.
To find everything, we use a blacklight to spot urine and moisture readings to trace how far it spread underneath. The blacklight inspection is free.
Why doesn’t spot cleaning fix it?
Store-bought sprays mostly treat the top of the carpet. They rarely reach the pad. Worse, the extra liquid can push the urine deeper and spread it wider.
Perfumed sprays only cover the smell up. Once the fragrance fades, the odor is back, and your pet can still smell it.
A regular carpet cleaning without urine treatment has the same problem. It adds moisture, which can wake the odor back up for a while if the source underneath hasn’t been treated.
What does professional pet urine treatment involve?
Here’s what our pet treatment and odor control process looks like:
- Find and map it. We inspect the carpet and follow the odor so no spots get missed. Ask us to check the corners and rooms your pets like best.
- Apply an enzyme treatment. We put down enough product to reach as deep as the urine went. The enzymes break down the residue that causes the smell.
- Let it work. Enzymes need time, so we give the treatment time to sit instead of rinsing it right out.
- Rinse it out. Truck-mounted hot water extraction then flushes out the broken-down residue.
- Heavy saturation gets more. If a spot is soaked deep, we can apply treatment below the surface and pull it back out with a subsurface extraction tool.
In most homes, this greatly reduces pet odor and removes most of it. Before we start, we’ll tell you where we expect good results and where we don’t.
When does the padding need to be replaced?
Sometimes cleaning isn’t the real fix. Replacing a section of pad may make more sense when:
- The pad has soaked up repeated accidents over a long time.
- The odor stays strong even after a full treatment.
- The urine has gone through to the subfloor, which may need its own treatment.
New pad costs far less than new carpet, and often only one section needs replacing. Old urine can also leave permanent color changes on the carpet itself. We’ll be upfront about both before you spend money on repeat cleanings.
What should you do right after an accident?
Quick action keeps urine out of the pad:
- Blot up as much as you can with white paper towels or a white cloth. Stand on them to soak up more.
- Don’t scrub. Scrubbing spreads the urine and roughs up the fibers.
- Blot a small amount of cool water onto the spot, then blot it up again. Don’t soak the carpet.
- Skip heavily perfumed products. They hide the smell from you but not from your pet.
If an accident has soaked in deep or keeps happening in the same place, it’s worth having a pro take a look.
What about urine on rugs and furniture?
Area rugs hold urine in their foundation, the base the yarn is woven into. Rugs with pet accidents do best with an in-plant wash at Silk & Shine Rug Spa, where the whole rug can be flooded and flushed. See our rug cleaning page.
On couches and chairs, urine soaks into the cushion. Fabric is tested before cleaning, and we treat the affected areas there too. See upholstery cleaning.
Frequently asked questions
Will the smell go away on its own?
Usually not. The salts left behind keep pulling moisture from the air, so the smell tends to come back on humid days until the source is treated.
Can urine be treated without pulling up the carpet?
Often, yes. Enzyme treatment and subsurface extraction work through the carpet. A pad that’s badly soaked may still need to be replaced.
Does pet treatment cost extra?
The blacklight inspection is free. Treatment is priced after we see how many spots there are and how deep they go, and you’ll know the price before we start.
Will my pet stop going back to the same spot?
Pets are drawn back to spots that still smell like urine. Treating the source can help discourage repeat accidents, but it can’t change your pet’s habits.
