There's a version of this industry where every homeowner gets the same proposal regardless of their crawlspace's actual conditions, their structural constraints, or their budget. You've probably seen it: one system, one price, heavy financing offers to make it feel accessible. That's not how we work.
Anthony Denatala has inspected crawlspaces in Greater Atlanta for over twenty years. He's seen the same full-encapsulation spec applied to below-grade block-wall spaces that needed something fundamentally different, and he's watched those jobs create new problems behind sealed plastic. He's also seen homeowners told they need a $12,000 system when a well-executed $3,500 reset would have solved the actual problem. The solution has to match the situation — the building science doesn't care what the sales sheet says.
Three solutions. One honest conversation about which one is right for your space.
The Three Tiers
Remediate the space and restore it to original builder-grade conditions. Clean the structure, replace the ground cover, re-seal what needs sealing. Not an upgrade — a clean, verified baseline with the mold problem eliminated and the moisture source addressed.
- Full mold remediation of framing and surfaces
- Existing vapor barrier removed and replaced (10-mil minimum)
- Vents inspected and repaired or sealed as appropriate
- Moisture source confirmed addressed before work begins
- Post-clearance moisture readings and documentation
- Annual maintenance program available
Budget-first homeowners. Spaces with manageable moisture and no active groundwater. Homes being prepared for sale. Situations where "clean and functional" is the right goal.
Anthony's named method for structurally constrained spaces — particularly below-grade crawlspaces where full wall encapsulation traps moisture rather than solving it. Sealed ground cover only. No wall vapor barrier. The open walls allow masonry and soil to dry toward the interior over time.
- Full mold remediation of all framing surfaces
- 20-mil reinforced sealed ground cover (floor only)
- Walls remain uncovered for controlled interior drying
- Commercial-grade dehumidifier sized for space (70–90 PPD)
- Exhaust system maintaining sustained low-humidity environment
- Annual follow-up inspection — standard at this tier
Below-grade crawlspaces with block foundation walls. Active capillary wicking or historic moisture migration through masonry. Spaces where full wall encapsulation would seal in an ongoing moisture source.
The premium enclosed system. Walls, floor, columns, access hatch — fully sealed. Paired with commercial dehumidification and exhaust. The right solution when your crawlspace structure, drainage, and moisture conditions make it appropriate.
- Full mold remediation prior to encapsulation
- 20-mil reinforced vapor barrier — floor and walls
- All seams, penetrations, and access hatches sealed
- Column wrapping included
- Commercial dehumidifier with continuous drain
- Annual maintenance program available
Above-grade crawlspaces with good drainage. Spaces with HVAC equipment inside the crawl. Homes where the investment in a complete sealed system is appropriate to the structure and value.
No solution gets installed until the moisture source is confirmed addressed. That means drainage, grading, plumbing, and any active water intrusion are verified resolved before a single square foot of plastic goes down. Sealing a wet space is not moisture control — it's concealment. We don't do that.
"Think of it like buying a car. Budget determines whether we get a standard model or a luxury build — but every car gets you where you need to go. What matters is that the solution is right for your structure, implemented properly, and that we're checking on it every year. Some clients don't need the full system. Some would be making a mistake with anything less. That's what the inspection is for."

One of the most consistent mistakes in this industry is installing the wrong step first. A dehumidifier running against uncontrolled groundwater runs constantly and never reaches target humidity. A vapor barrier installed over saturated soil seals in what it was meant to remove. The sequence matters as much as the materials.
The Right Order of Operations
Longevity Requires Observation
Every solution SBG installs is designed for longevity. Annual maintenance is how that longevity gets confirmed. Atlanta's climate — clay soil, summer humidity regularly reaching 75–95% in uncontrolled crawlspaces, freeze-thaw cycles — creates conditions that change over time. A system that was functioning correctly at installation can develop issues at the perimeter, at penetrations, or from changes in the surrounding soil. Catching those changes early is how a three-year problem stays a one-year fix.
The annual visit also creates a documented history for the property — a record of moisture readings, system condition, and any changes observed. That record is useful at resale and useful if an insurance event occurs.
Annual maintenance pricing is determined at initial job close based on system type and crawlspace size. Most residential spaces: $150–$250/yr.
Which Solution Fits Your Space?
The short answer is always: we inspect first, then tell you. The longer answer depends on these factors:
| Condition | Builder Grade Reset | Ground Cover Enclosure | Full Encapsulation |
|---|---|---|---|
| Crawlspace grade relative to exterior | Either | Below grade preferred | Above grade preferred |
| Foundation wall type | Either | Block / masonry with wicking | Poured concrete or block with good drainage |
| Active groundwater or hydrostatic pressure | Must be resolved first | Can be managed with drainage + open walls | Must be resolved before encapsulation |
| HVAC equipment in crawlspace | Less critical | Supported but less optimal | Ideal — equipment benefits from conditioned space |
| Budget range | $1,800–$3,500 | $3,200–$5,500 | $5,000–$9,500 |
| Timeline to stable conditions | Immediate post-remediation | 6 months–2 years for full soil drying | Immediate if source is addressed |
Common Questions
Start With an Inspection
Every solution recommendation comes from a forensic inspection of your actual space — not a template. Anthony Denatala, CMRS, conducts every inspection personally.
