There is nothing more harmful to a shower or tub than mold. While it’s better not to have mold in the first place if you do have mold and need to get rid of it, here are some simple steps to avoid a dangerous and costly situation!
First things first, check to see if you have proper bathroom ventilation or some kind of fan unit. In some states this is actually required now, but for many years not having some kind of fan went unnoticed.
Additionally, here are some steps the EPA offers to keep away or clean mold/mildew:
- Fix leaky plumbing and leaks in the building envelope as soon as possible.
- Watch for condensation and wet spots. Fix source(s) of moisture problem(s) as soon as possible.
- Prevent moisture due to condensation by increasing surface temperature or reducing the moisture level in air (humidity). To increase surface temperature, insulate or increase air circulation. To reduce the moisture level in air, repair leaks, increase ventilation (if outside air is cold and dry), or dehumidify (if outdoor air is warm and humid).
- Keep heating, ventilation, and air conditioning (HVAC) drip pans clean, flowing properly, and unobstructed.
- Vent moisture-generating appliances, such as dryers, to the outside where possible.
- Maintain low indoor humidity, below 60% relative humidity (RH), ideally 30-50%, if possible.
- Perform regular building/HVAC inspections and maintenance as scheduled.
- Clean and dry wet or damp spots within 48 hours.
- Don’t let foundations stay wet. Provide drainage and slope the ground away from the foundation.
Sometimes old showers or tub you have inherited have it from misuse or just plain old age. If you find mold, you should call in a professional to help you remove it. If you suspect your unit has mold, you’re obviously going to want to take safety precautions to confirm your suspicions. There are some rules of engagement, per the EPA, that ensures you are doing so safety.
- Do not touch mold or moldy items with bare hands.
- Do not get mold or mold spores in your eyes.
- Do not breathe in mold or mold spores.
- Consult the EPA Personal Protective Equipment (PPE) and containment guidelines.
- Consider using PPE when disturbing mold. The minimum PPE is an N-95 respirator, gloves, and eye protection.
If all of this seems too much for you and you are in the market for a remodel – we highly recommend our Bath Fitter systems. Since mold only grows in the presence of moisture the Bath Fitter system seals and waterproofs the underlying area to ensure that mold will not grow. We achieve this by thoroughly cleaning and disinfecting the existing surfaces prior to installing the new tub and wall. And if it is not a case where we can simply disinfect the surface below we will tear your current tub/shower all the way down to the studs and put in fresh green board (a water resistant drywall) behind our system.
