Intro:
Here’s the thing: Encapsulation is amazing—but so is saving money when you don’t need the Cadillac option.
If your crawlspace is a nightmare (mold, rot, standing water), go big. But if it’s just a little damp? You might get 80% of the benefit with a few smart, low-cost steps.
Let’s compare.
Option 1: Full Encapsulation (The Cadillac)
What it includes:
Sealed vents
Heavy-duty vapor barrier
Wall insulation
Professional sealing and taping
Dehumidifier
Pros:
✅ Maximum moisture control
✅ Lower energy bills
✅ Adds resale value
Cons:
❌ Price tag: $8,000–$20,000
❌ Overkill for some homes
Option 2: Simple Fixes (The Budget Route)
You don’t always need a $15k job. Here’s what you can do:
Remove wet insulation and debris
Lay down a basic vapor barrier (even 6-mil plastic is better than nothing)
Seal crawlspace vents
Install a dehumidifier
Monitor humidity with a simple humidistat
Pros:
✅ Costs way less (often under $2,000 if DIY)
✅ Solves most moisture issues
✅ Easier to DIY
Cons:
❌ Not as airtight as full encapsulation
❌ Dehumidifier works harder if space isn’t sealed
Which One Should You Choose?
If your budget allows and your crawlspace is a swamp, encapsulate. If you’re just battling humidity or don’t want to drop a fortune, start simple.
Sometimes good enough is… good enough.
