Subfloor Ventilation May Be Your Best Investment This Year And Here’s Why

Nothing beats the feeling of coming home to a place where you can relax and create special memories with your family. This is the reason homeowners spend money on cleaning tools and home maintenance services. You want to keep it safe, healthy, and pest-free. But when it comes to home maintenance services, very few pay close attention to what is happening right under their homes, the subfloor, specifically subfloor ventilation.

Subfloor ventilation works by replacing damp air with dry, fresh air in your home. It helps get rid of excessive moisture in your home to protect against molds, mildew, and pests. This also protects the structural stability of your house as it prevents the wood from absorbing too much moisture.

Why Should Your Home Have Sub Floor Ventilation


Because sunlight never reaches the subfloor of your house, it is an area where condensation occurs a lot. Condensation buildup will cause structural damage to your home, especially the wooden support structure of your house. If uncorrected, condensation may cause such destruction that it would cost a lot of money to fix it. With proper subfloor ventilation, moisture in the air does not have time to condense in the subfloor of your home.


Radon gas is an odorless radioactive gas that emanates from the soil, especially if your house is built on soil with natural uranium deposits. Yes, radon is dangerous and may cause lung cancer. Subfloor ventilation keeps radon from rising through the floor and into your home.

Molds, termites, rats, and roaches

Without good ventilation, condensation happens inside your subfloor, making it a city of rats, roaches, centipedes and other destructive pests. Not only that, condensation may also cause molds to grow and ruin wooden floors and make your family sick.

Prevents bad odor from entering your living space

If the subfloor of your home is not well-ventilated, stale air from it may enter your house. It may also cause respiratory problems like asthma and cough. If someone from your family is allergic to molds, a badly ventilated subfloor may cause health problems.

Back drafting in case of fire

In case of fire, a subfloor that is not well-ventilated may cause a backdraft of air to enter into the house and make the fire stronger.

Do not take subfloor ventilation for granted. A well-ventilated subfloor makes your home unattractive to pests and helps maintain structural stability. The money it will cost to install better subfloor ventilation is outweighed by the many benefits you will get from it.

I called Hero Plumbing to unblock a shower drain and was unable to get a quote over the phone, but Sam the owner was here same day. After his first try, he made quick work of the blockage. I opted to also get the acid cleaner stuff poured down. Sam had run out, but made a trip to go pick some up to finish the job. If you opt for this treatment make sure you can easily air the bathroom as it’s extremely strong and produces a lot of fumes. Great Service and Honest Pricing.

Hero Plumbing has been excellent since there first phone call.
I spoke to a gentlemen names Sam which he organised a technician to come and replace our hot water heater.
The technician was excellent called me 30mins before arrival explained the whole job to me and gave me an upfront price.
Excellent work Hero team.
We are a Hero member now and always look forward to working with them.

Jared Evans

We've used Hero Plumbing previously. Both times reliable and flexible with changing times (helpful during covid ISO periods!)
Hayden was on time and explained the issue clearly, fixed it,then also did some extra checks on water pressure and taps to ensure there were no underlying issues.
Would recommend their services.

Hayden Davidson

Brilliant service from the first phone call to Hero Plumbing as Sam the manager booked us in very efficiently. I received a confirmation  email, a phone call on approach and all went smoothly & work conducted was beautiful . The team did a great job even dig up on our sewer and cut concrete & repaired the issue and our sewer is running like a dream.
Thanks for your great efforts guys!


Victoria Barmina

I knew Sam when he was working alone. And from the first time I was pleasantly surprised by his work. A little later I found out that he has his own business. I am very happy about that. And I am very glad for myself that I have such a company that I can always rely on.

Thank you for your work. People need you very much.
