A strong urine odor in your home can be unpleasant and embarrassing. The smell is often caused by pet accidents, but it can also come from mold, mildew, dirty carpets, and other sources. The good news is there are many effective ways to get rid of urine odors in your house.
What causes urine odors in a house?
Some common causes of urine odors indoors include:
- Pet accidents – This is one of the most common sources of urine odor in homes. Pets may urinate on carpets, floors, furniture, and other places.
- Leaking pipes or plumbing – Leaks in pipes or toilet seals can allow urine odors to spread.
- Dirty litter boxes – A dirty litter box is a prime source of ammonia odor.
- Diaper pails – Used diapers can create powerful urine smells if not emptied regularly.
- Mold and mildew – Mold that grows in damp areas where urine has collected can produce strong musty odors.
- Old stains – Urine stains that were not properly cleaned can continue emitting odors long after the accident.
Tips for eliminating urine odors
Here are some effective methods and tips for getting rid of urine smells in your home:
Find and clean all urine stains
The first step is to locate all affected areas. Look for stains on carpets, floors, furniture cushions, and other places pets may have had accidents. Turn off overhead lights and use a UV blacklight to help identify old or dried stains. Once located, clean stains thoroughly with an enzymatic pet odor neutralizer. This will help break down the compounds causing odors.
Clean and deodorize carpets
Shampoo carpets using a machine rental or professional carpet cleaning service. Make sure to use a pet odor neutralizing cleaner. After carpets are dry, sprinkle liberally with baking soda. Let it sit for several hours before vacuuming up. The baking soda will absorb odors trapped in the carpet fibers.
Replace soiled cushions and bedding
Urine stains and odors can be incredibly difficult to remove from cushions, mattresses, and other fabric furnishings. If the stains have soaked deep into the stuffing, it may need to be replaced. Toss out any pet bedding, pillows, or fabrics with urine stains.
Clean and disinfect floors
Mop tile, vinyl, and sealed hardwood floors using a disinfecting cleaner or vinegar solution. For unsealed wood floors, use a specially formulated pet odor neutralizing floor cleaner. Get into corners, behind furniture, and under appliances where urine may have seeped.
Improve ventilation and airflow
Open windows periodically to circulate fresh air. Use fans, air purifiers, and dehumidifiers to improve airflow and reduce odors. Keep bathroom and kitchen exhaust fans running for a while after use to remove moisture.
Replace old Subflooring
If urine has soaked through to the subfloor underneath carpeting, the subfloor may need replacing. Plywood and particleboard subflooring tend to absorb odors more readily than wood planks.
Clean out plumbing traps
Fill sinks, tubs, and floor drains with hot water and baking soda. Flush drains thoroughly. Urine odors can gather in pipes and floor drains.
Seal tile grout lines
Use a sealant designed for grout to form a protective barrier over porous grout lines. This will make tile floors less prone to absorbing urine odors.
Limit moisture and humidity
Fix any leaks. Vent clothes dryers outside and run bathroom fans when showering. Use dehumidifiers to control humidity. Moisture allows urine odors to persist and mold to grow.
Advanced urine odor removal methods
For severe or persistent urine odors, you may need to take more advanced countermeasures:
- Ozone machine treatment – Ozone generators can remove odors, but can’t be used when people or pets are present.
- Enzyme odor removers – Professional strength enzyme cleaners are applied and allowed to dry on affected areas.
- Antimicrobial foggers – Antimicrobial foggers use an atomized spray to penetrate all surfaces and pores.
- Hydrogen peroxide and baking soda – Mixing hydrogen peroxide with baking soda and applying to carpets can help lift stains and deodorize.
- Vinegar and water – Wiping down walls, baseboards, and floors with a vinegar and water solution neutralizes odors.
- Paint – Kilz Primer or other sealing paints can encapsulate urine odors in drywall, subfloors, and other porous surfaces.
Preventing urine odors
Here are some tips to help avoid urine odor problems in your home:
- Clean up accidents right away
- Clean litter boxes frequently
- Let your pet outdoors often
- Use belly bands and diapers when needed
- Restrict pets from carpeted rooms or put down waterproof covers
- Consider steam cleaning or shampooing carpets and upholstery every 3-6 months
When to call a professional
Contact a certified odor control specialist if:
- Odors persist after thorough cleaning
- The source cannot be located
- Odors return quickly after removing
- Urine has soaked into subflooring
- Advanced treatments like ozone or antimicrobial fogging are needed
Professionals have commercial-grade cleaners, odor sealing paints, and powerful equipment to eliminate severe or challenging urine smells.

The keys are finding and removing the source, deep cleaning and deodorizing affected areas, sealing porous materials, and improving airflow and ventilation. With patience and persistence, you can successfully eliminate even severe urine odors for good. Don’t live with unpleasant urine smells – take action to freshen up your home’s air today.
