Got odors?

Is it pet urine, mildew, cooking odor or a wet dog smell in your carpet?

The above odors are the most common “pew” complaints we hear on a daily basis.

Do you smell it? that smelly smell dog face

But the fact is, yucky smells can come from a variety of sources.

While your first instinct may be to DIY the heck out of the odor, let’s take a look at why that’s probably not your best bet.

And why you may need to bring in the pros. (We’re even letting you in on carpet deodorization cost so you know what to expect.) 

Why DIY Deodorizers Don’t Cut It

There are all kinds of products sold at your local hardware, grocery or pet store that “claim” to be safe on carpet and remove odors.  

They’re attractive because they SEEM to offer a carpet deodorization cost that’s lower than the alternative – calling a professional carpet cleaning company.

The problem is, most of these products only cover up the odor. They don’t last long and certainly don’t kill the bacteria that’s causing the odor in the first place. 

You end up with a hint of the stinky odor mixed with the scent of the spray. EW.

Some deodorizers claim to remove pet odor from the carpet. It’s one of the most difficult odors to remove for many reasons, such as:  

  • Did the pet urine soak through to the backing of the carpet? 
  • Did it soak into the pad, or – even worse – the subfloor?  
  • Was it a dog or a cat?  
  • How many times did the pet wet in the same area?

Again, the pet urine deodorizer may provide a temporary cover-up of the smell.  But, if it doesn’t have a professional grade of live enzymes, or if the affected area is not professionally cleaned prior to the enzyme treatment, the odor simply will not come out. DANG.

Most homeowners treat the surface of the carpet and wonder why they still have an odor. 

This could be for a couple reasons.

If the back of the carpet, pad or subfloor have been damaged, the carpet needs to be pulled, treated on the back, the pad then needs to be replaced, and the subfloor needs to be sealed.  

That’s a lot of work for the average homeowner.

But that’s not the only danger of taking the DIY approach. 

If an over-the-counter deodorizer is used and too much is applied to the carpet – and not extracted properly – the solution soaks into the carpet and breaks down the backing, causing a bubble where it was applied.  

And you’re NOT saving money on carpet deodorization cost. 

In case you weren’t sure, that’s bad.

Now, let’s get on with what DOES work when it comes to carpet deodorizing. 😊

There are two different types of professional deodorization that we recommend. (HINT: HK does too!)

Saving on Carpet Deodorization Cost 

You’re wasting money – and time – when you try every over-the-counter product on the market.

When you consider what you’ve spent on methods that didn’t work, you’ll see why carpet deodorization cost goes down when you let the pros handle the job

Topical deodorization

A topical deodorizer is applied by a technician – typically with a pump sprayer – after a professional carpet cleaning.  

The deodorizer kills the molecules that are causing the odor (cooking odors, light smoke, pet dander, musty odors, etc.).  

Keep in mind, a topical deodorization will not work if a large amount of liquid, such as pet urine, has penetrated the carpet.

Some homeowners choose to have a topical deodorizer applied because they like the fresh scent that’s left behind after the carpet has been cleaned. 

The cost to apply a topical deodorizer is $.37 per square foot.

Enzyme deodorization

Enzyme deodorization is applied in several different applications. It can be applied topically, injected into the backing of the carpet or saturated over an affected area and then extracted with a water claw.

The enzyme deodorizer kills the bacteria that’s causing the odor. When applied, a live enzyme can continue to work for up to seven days after it’s applied. As it continues to break down the bacteria, the odor continues to dissipate.  

In extreme cases – especially with pet urine – your carpet may need to be treated one or two more times.

The enzyme kills pet urine, heavy fire/cigarette smoke, mildew, vomit etc.

For heavy pet urine, carpet will often be cleaned on the surface, then pulled so the backing can be cleaned and treated. The pad is replaced and the floor beneath gets sealed. 

This can be a costly service, BUT, it’s less expensive than replacing the entire room of carpet and pad.

Their are different pricing levels for this service:

When applied topically, it’s $.37 per square foot

When the carpet is pulled, the pad’s replaced and both are treated along with the floor, you can expect to pay upwards of $225.

The use of a water claw starts at $35 (plate size) and up.

What About Stubborn Odors?

Carpet deodorization options for stubborn odors

  1. Ozone treatment
  2. Fogging

For really persistent odors that are in your walls, floor and furnishings, such as cigarette smoke and cooking odors, there are two treatments that can be done to remove the odor.

Ozone treatment

An ozone machine can be placed in the room for 24+ hours to remove the smell. Your home or room cannot be occupied during this process.

The cost to ozone is $250+ per room.


A fogging can be done in the room of your home that has a strong odor. This process is primarily used when a smoker leaves the home. Like ozone, you can’t be in your home while the fogging is being done.

The cost for fogging is $250+ per room.

The More You Know...

Understanding the options for your stinkiest situations is the first step in making sure you get rid of the odor for good.

And having a head’s up about what it will cost helps you to be prepared in case you ever find yourself in a smelly spot.
