How to Get Rid of Unpleasant Odors From Under Your Deck

To fully enjoy outdoor living, you’ll need to make sure your deck is not only lovely and comfortable, but clean-smelling as well. So, if you’ve recently noticed an unpleasant odor coming from under the deck, you might want to deal with it promptly. Here are some handy tips.  

How to Get Rid of Unpleasant Odors From Under Your Deck

1. Identify the Cause of the Stench

You’ll probably be able to take care of the issue yourself before tearing up the deck or calling a professional. How you deal with the unpleasant odor will depend on what’s actually causing it. The most common reasons may include:

  • Animals. It’s not uncommon for small animals, such as squirrels, raccoons, rabbits, and mice, to find their way under your deck to nest or find food. If alive, they leave behind droppings that cause a bad smell — that’s bad enough. What’s worse is when the creature actually dies under your deck.
  • Mold and mildew. The shady and damp space under the deck is the perfect breeding ground of mold and mildew. You’ll know their presence by their stale and musty odor.
  • Pets. Have you noticed your pets entering or exiting the space under your deck from time to time? The urine or excrement from your canine or feline friends may be the reason for that terrible odor. 

2. Eliminate the Cause


Taking care of this particular issue may not be as complicated as roof maintenance, but you should still take the necessary precautions. Whether the reason for the smell is decomposing material or animal droppings, you have to wear a face mask, work gloves and protective eyewear. Find where the offensive material is, put it inside a plastic bag, and then tie it shut. You can use a garden trowel or long-handled grabbing tool if you’re squeamish about handling the material with your gloved hands.

3. Clean Up After

Just because you’ve removed the offensive material doesn’t mean the odor will disappear instantly. The smell, after all, may have seeped into the deck boards already. The treatment option will depend on the cause of the odor. For cat urine, there are over-the-counter pet odor eliminators or neutralizers you can use. Baking soda can be swept around with a broom to fill the gaps between the boards and get rid of dog urine. As for mold and mildew, you can clean the deck using a bleach and water solution.

I just wanna give a shout out to one of your guys who jumped out of vehicle to help me push my van out from 62 onto coker Butte this morning awesome job and thank you so much..

No hassles, no stress roofing contractor.

We've worked with a number of contractors over the years doing home improvement projects and I can say that, without question, working with Pressure Point was about as easy as it gets.

Everything about the project, from sales all the way to final inspection, went like clockwork and without a hitch.  They delivered more than they promised, on time and within budget.   We could not have been happier with their personnel, products and services.  Highly recommended!

I've changed my review from a 1 star to a 4 stars. Matt Stone got right on a pretty poor job done installing a skylight. He had his guys remove the skylight, move it, repair the roof and inside ceiling to its original state, paint it, repair some external trim that was damaged, and all within a few days after talking to him about the multiple problems. It was really an eyesore from the inside. I'd give a 5 star if this had been done well the first time. The skylight just didn't fit the space I first wanted it and was told it would. More communication about the potential problems might have allowed this to be done right the first time. But, Pressure Point Roofing gets 5 starts for making amends and correcting a pretty ugly problem, very fast! Thank you.

I needed someone to come out to take a look at a leaky roof. I contacted Pressure Point Roofing, Inc. and they came out the same day. They gave me a quote to fix the problem and I agreed to their terms. It was about 4PM and I knew they closed at 5PM but they stayed and fixed the leak at no additional cost. I was very happy and impressed. Would recommend them to anyone. Thank you Pressure Point Roofing for earning our families trust. Will definitely be doing business with you again.

Wouldn't be good if I didn't think the best of my own company right?!

Matt Stone

Excellent experience, prompt and professional estimate, showed up on schedule (actually a day early) and did a thorough and complete job. All personnel were professional,polite and great at their jobs. Would recommend to anyone.

I am so happy I chose Pressure Point to replace my 40-year-old roof.  The crew was professional, efficient, and answered all my questions, addressed the few concerns I raised, and made me feel comfortable, trusting them with such a big project.  I couldn't be happier with their work and the look of my new roof.
