Weird Smells in Your Home? Here’s How to Get Rid of Lingering Odours for Good

Nothing impacts the comfort of a home quite like an unpleasant smell. Whether you’ve recently purchased a property, are preparing to sell, or simply want a fresher living environment, lingering odours can make even the nicest home feel less inviting.

At Team Prata Real Estate, we’ve toured thousands of homes across Trent Hills, Northumberland County, and Durham Region. One thing we’ve learned is that odours are often one of the first things people notice when they walk through the door.

The good news? Most household odours can be identified, treated, and eliminated with the right approach.

Why Odours Matter More Than You Think

Smell has a powerful connection to emotion and memory. A fresh, clean smelling home immediately creates a positive impression, while unpleasant odours can leave buyers wondering what other issues may be hiding beneath the surface.

Even if you’re not planning to sell, removing unwanted smells can significantly improve your enjoyment of your home and contribute to a healthier indoor environment.

Musty or Mouldy Smells

A damp, musty smell is one of the most common odours homeowners encounter, especially in older homes, cottages, basements, and rural properties throughout Northumberland County.

Common Causes

• High indoor humidity
• Basement moisture
• Leaking plumbing
• Roof leaks
• Hidden mould growth
• Poor ventilation

How to Fix It

Start by identifying the source of the moisture. Check:

• Basements and crawl spaces
• Under sinks
• Around windows
• Attics
• Bathrooms

Clean small visible mould areas using appropriate mould cleaning products and improve ventilation where possible. Running a dehumidifier can dramatically reduce moisture levels and improve air quality.

If mould covers a large area or continues to return, professional mould remediation may be necessary.

Why It Matters

Mould can affect indoor air quality and may contribute to respiratory issues, allergies, and other health concerns. Addressing the source not just masking the smell is essential.

Cigarette Smoke Odours

Smoke odours can be surprisingly stubborn because residue settles on nearly every surface in a home.

Common Areas That Hold Smoke Smells

• Drywall
• Ceilings
• Carpets
• Curtains
• Upholstered furniture
• HVAC systems

How to Remove Smoke Odours

A thorough cleaning should include:

• Washing walls and ceilings
• Cleaning vents and ductwork
• Replacing furnace filters
• Deep cleaning carpets and upholstery

For heavily affected homes, applying an odour blocking primer before repainting can make a dramatic difference.

In severe cases, carpet replacement may be the most effective solution.

Pet Odours

We love our pets, but over time they can leave behind odours that become difficult to notice when you live with them every day.

Common Sources

• Pet dander
• Fur accumulation
• Saliva
• Oils from skin and coats
• Accidents on carpets or flooring

How to Eliminate Pet Smells

Start with:

• Vacuuming frequently
• Washing pet bedding
• Cleaning furniture
• Replacing HVAC filters
• Using pet safe deodorizing products

Carpets and upholstered furniture often benefit from professional steam cleaning.

Urine Odours Require Special Attention

If urine has soaked into carpet padding or subfloors, standard cleaning products may not solve the problem.

Enzyme based cleaners are typically the most effective option because they break down the compounds causing the smell rather than simply masking it.

For older stains, replacing affected flooring materials may be necessary.

Sewer or Rotten Egg Smells

Few smells are as unpleasant or potentially serious as a sewer or rotten egg odour.

Possible Causes

• Dry plumbing traps
• Blocked vent stacks
• Drain issues
• Sulphur in well water
• Sewer line problems

Quick Fixes to Try

Run water in:

• Guest bathrooms
• Floor drains
• Laundry tubs
• Basement sinks

Unused plumbing fixtures can dry out, allowing sewer gases to enter the home.

You can also try cleaning drains with baking soda followed by hot water.

When to Call a Professional

If the smell continues after basic troubleshooting, a plumber should inspect the system.

Important Safety Note

A strong rotten egg smell can sometimes indicate a natural gas leak. Utility companies add a sulphur like scent to natural gas specifically to help homeowners detect leaks.

If you suspect a gas leak:

• Leave the home immediately
• Do not operate electrical switches
• Avoid open flames
• Contact your gas provider or emergency services from a safe location

Don’t Forget Your HVAC System

Many homeowners overlook the role their heating and cooling system plays in indoor odours.

Dirty filters, dust buildup, moisture in ductwork, and neglected air handlers can circulate unpleasant smells throughout the home.

Regular maintenance can help keep indoor air fresher year round.

Consider:

• Changing filters every 1-3 months
• Having ducts inspected when necessary
• Scheduling annual HVAC maintenance

Natural Ways to Freshen Your Home

Once the source of the odour has been addressed, these simple methods can help maintain freshness:

Open the Windows

Fresh outdoor air remains one of the most effective and inexpensive solutions.

Use Activated Charcoal

Activated charcoal absorbs odours naturally and works well in:

• Basements
• Closets
• Mudrooms
• Storage areas

Add Houseplants

Many indoor plants help improve air quality while making your home feel more welcoming.

Maintain Humidity Levels

Aim for indoor humidity between 30% and 50% to help prevent mould growth and stale air.

A Fresh Smelling Home Feels Like Home

Eliminating unpleasant odours is about more than making a home smell better. It’s about creating a space that feels clean, healthy, and comfortable for your family and guests.

Whether you’ve recently moved into a new property, are preparing your home for sale, or simply want a fresher living environment, addressing odours at the source is always the best long term solution.

A clean smelling home not only improves everyday living but can also make a significant difference in buyer impressions and overall property appeal.
