Living in the Sunshine State has its perks, but Florida's unique climate can be tough on mobile homes. One crucial component that often gets overlooked is the vapor barrier. At Florida Vapor Barrier, we've seen firsthand how a failing vapor barrier can lead to serious issues. But how do you know when it's time for a replacement? We cover the most common signs its time for a new vapor barrier below.
The Florida Climate Challenge
Before we jump into the signs, let's talk about why vapor barriers are so critical in Florida:
Humidity that just won't quit
Surprise rain showers (almost daily in some areas!)
The occasional flood threat
Heat that can make you feel like you're living in a sauna
All these factors make your vapor barrier work overtime. So, what happens when it starts to give up?
Red Flag #1: Musty Smells that will NOT go away
Is there a lingering smell that just won't go away, no matter how many candles you light or how many times you clean the house. Well, chances are it's moisture building up inside your home, leading to mold growth.
(Just incase you are not wondering how mold grows, when hot outside air meets cold inside air, it causes moisture to increase, this causing mold.
Red Flag #2: Soft Spots that feel like 'Mush'
If you're tiptoeing around soft spots in your floor, it's not a game anymore. It's a clear sign your vapor barrier is letting moisture attack your home's structure. If you floors feel like they are about to cave in, they probably are, immediate action is required in most situations.
Safety Alert: Soft floors aren't just annoying – they're dangerous. We've seen first-hand someone fall through their bathroom floors due to decaying flooring and soft spots.
Red Flag #3: Your Windows Are Crying (AKA Condensation Overload)
If your windows look like they're sweating more than you do during a Florida summer, your vapor barrier might be waving the white flag. Excessive condensation is a sure sign that moisture is getting where it shouldn't.
Pro Tip: Wipe a window in the morning. If it's damp again within an hour, it's not normal Florida humidity – it's a vapor barrier problem.
Pro Pro Tip: Also check for condensation around A/C vents, doors, and on the air unit itself.
Red Flag #4: Your Energy Bill Is Through the Roof
Has your energy bill suddenly skyrocketed? Before you blame it on cranking the AC, consider this: a failing vapor barrier can make your HVAC system work harder than a tourist trying to get a tan in one day.
Money-Saving Moment: A new vapor barrier could pay for itself in energy savings. It's an investment in your wallet and your comfort!
This is very important to understand. The DOE also gives tax credits for energy efficient upgrades. This includes Vapor Barrier Services. (Advise with a tax professional)
Red Flag #5: Your Home Has Seen More Summers Than You Have
If your mobile home is old enough to join AARP, chances are its vapor barrier is past its prime. Even if you're not seeing obvious signs, an aging barrier is like a ticking time bomb.
Most mobile homes in the state of Florida are built before 1995. These mobile homes usually had material called "buffalo board". It is a particle board that absorbs moisture instead of defending against it. This is now an issue. These Vapor Barriers have not been up to code for the past 20 years. All newly manufactured mobile homes require 6 mil vapor barrier.
