Pet Urine Odor in Carpet
in Sioux Falls, SD
Pet urine is one of the most common carpet problems we deal with in Sioux Falls. When a dog or cat goes on the carpet, the liquid runs straight through the fibers and soaks into the padding. Once it dries, it leaves behind urine salts that smell worse every time the humidity rises, which happens here in the summer and again when furnaces kick on in January.
Quick Answer
Pet urine soaks through carpet fibers and into the padding beneath, and Sioux Falls homes with forced-air heating spread that smell through every room fast. Store-bought sprays cover the odor for a day or two but don't break down the urine crystals. A professional treatment flushes the padding and uses an enzyme solution that actually eats the waste causing the smell. If you're noticing the odor more in winter when the heat runs constantly, call (605) 250-3667 before it gets into the subfloor.
Telltale Signs
Warning Signs to Watch For
- A strong ammonia smell that gets worse when the heat or AC turns on
- Yellow or brownish stains on the carpet surface, sometimes faint
- Pets returning to the same spot repeatedly to sniff or mark again
- Smell is stronger in one room even after cleaning the visible stain
- Padding feels stiff or crusty when you pull back a corner of carpet
- Odor gets noticeably worse after it rains or humidity goes up
Root Causes
What Causes Pet Urine Odor in Carpet?
Urine Soaked Into Padding
When urine hits the carpet it passes through within seconds and saturates the foam padding below. The padding holds several times more liquid than the carpet itself, so cleaning only the surface leaves most of the urine untouched.
The Fix
Enzyme Treatment with Padding Flush
We saturate the area with an enzyme cleaner that breaks down urine proteins at the source. In heavy cases we pull the carpet back and treat the padding and subfloor directly before reinstalling.
Urine Crystals in Subfloor
In Sioux Falls homes built before 1980, subfloors are often bare plywood or OSB board that absorbs urine over years of repeated accidents. Once the urine dries it forms crystals that release odor every time moisture is present, and no amount of carpet cleaning above reaches them.
The Fix
Subfloor Sealing and Carpet Replacement
The affected subfloor section gets cleaned, treated with an odor-blocking sealant, and the old padding is replaced. Trying to keep the original padding when the subfloor is contaminated never works long term.
