Georgetown is the county seat of Sussex County — and its inland location doesn't protect it from mold. Older downtown homes, a growing residential population, and the humidity that comes with being in the heart of Delaware's coastal plain all contribute to a mold environment that demands attention.
About Georgetown
The town's housing stock is diverse: a historic downtown with homes dating to the 18th and 19th centuries, mid-century neighborhoods that form the residential core, and newer developments on the outskirts that have grown with the county's population. Each era of construction brings its own moisture vulnerabilities, and Georgetown's position as the county's commercial and government center means a steady population of year-round residents who need their homes to be healthy, functional spaces.
Georgetown, Delaware
Georgetown's historic district contains some of the oldest homes in Sussex County. Pre-20th century construction often lacks modern vapor barriers, and original crawlspaces were not designed for today's humidity levels. Mold in these homes can be deeply embedded in original construction materials — plaster, wood lath, and original framing — and requires careful assessment before any work begins.
Georgetown's inland location doesn't eliminate moisture risk — it just changes its character. Rather than ocean humidity, Georgetown homes deal with the natural humidity of Delaware's coastal plain, seasonal rainfall, and the ground moisture that comes with the area's relatively flat topography and high water table. These are slower, quieter moisture sources than ocean air, but they're persistent.
A significant portion of Georgetown's residential neighborhoods were built in the 1950s through 1980s. These homes used construction practices and materials that are now 40-70 years old. Original insulation has degraded, original caulk and sealants have failed, and crawlspaces that were adequate when built may no longer be performing as intended. Moisture intrusion in these homes is often gradual and goes unnoticed until it's significant.
Georgetown has grown significantly as Sussex County has expanded. New residential developments on the town's perimeter bring modern construction — but as discussed, new construction is not immune to moisture problems. Construction moisture, fiberglass batt insulation, and the county's ambient humidity create conditions for mold in new homes as well as old ones.
The Science of Mold
There's a lot of misinformation about mold. We believe in doing the work right, and that starts with understanding the biology, the statistics, and the real health impacts based on federal and peer-reviewed data.
Mold is a fungus, not a plant. In nature, it's an essential decomposer. Without mold breaking down fallen leaves and dead wood, forests would be buried in their own debris. Outdoors, mold operates in open air where spores are diluted.
Indoors, the equation changes. Your home is a closed environment. When mold grows inside, it's doing its natural job — digesting organic matter — but the "matter" is your drywall paper and wood framing. In an enclosed space, spore concentrations spike, turning a natural process into a structural and health hazard.
The EPA and CDC link indoor mold to coughing, wheezing, and upper respiratory infections. A 2007 EPA-funded study estimated that 21% of US asthma cases (about 4.6 million people) are associated with dampness and mold at home.
Beyond respiratory issues, emerging research connects prolonged mycotoxin exposure to chronic immune activation and neurological symptoms like headaches and fatigue. Importantly, the EPA notes that dead mold is still allergenic — which is why killing mold isn't enough; it must be physically removed.
Many "professionals" just spray bleach or biocides on drywall and call it a day. This violates the ANSI/IICRC S520 industry standard. Mold grows root-like structures (hyphae) deep into porous materials. Sprays only treat the surface.
A 2013 peer-reviewed study evaluated 5 antifungal agents and found that when the chemical dilutes, dormant spores simply resume growth. This is why our process relies on physical removal of affected drywall first, followed by HEPA air scrubbing, and only then using EPA-registered sanitizers on the remaining structural framing.
How We Work
Every job follows the same four steps — regardless of the size of the problem or the town it's in. We don't cut corners.
We look at what's there — not just what's visible. The moisture source, the extent of the damage, and what materials are involved all factor into the approach.
Before any removal begins, the affected area is contained to prevent mold spores from spreading to other parts of the home. This is not optional.
Compromised drywall and insulation are physically removed. Remaining structural surfaces are then treated with Fiberlock ShockWave to sanitize the area.
New drywall is installed, finished, and painted. The goal is a repair that you can't see — walls that match the surrounding area and won't give the problem a place to return.
What We Use
Professional mold remediation requires professional products. Here's what we use and why.
An EPA-registered, hospital-grade disinfectant and mold remediation product. ShockWave uses quaternary ammonium compounds that penetrate porous surfaces — unlike bleach, which only affects the surface. It's on the EPA's List N and is used by professional remediation contractors nationwide.
Shellac-base primer is the standard for sealing water stains on drywall. It blocks tannin bleed and prevents stains from telegraphing through paint. Used on intact drywall where the paper facing is undamaged and the board is structurally sound.
Used when the paper facing of the drywall has been damaged by moisture. GARDZ penetrates and consolidates the damaged surface, creating a stable base for joint compound and paint. It's not always necessary — but when the paper is compromised, it's the right call.
During mold removal, airborne spores are a real concern. The Festool SYS-AIR HEPA air filtration system captures fine particles — including mold spores — from the air in the work area. This protects both the occupants and the rest of the home during the remediation process.

Yes. Inland location reduces some moisture risks but doesn't eliminate them. Delaware's coastal plain has naturally high humidity, and Georgetown's water table is relatively high. Older homes in Georgetown have had decades to accumulate moisture in their walls and crawlspaces. The beach towns get more attention, but Georgetown homeowners face real mold risks.
Older homes require more careful assessment. Original plaster walls, wood lath, and pre-modern insulation all behave differently than modern drywall. We assess each surface individually and won't recommend replacement unless it's genuinely necessary. Preserving original construction materials is always the preference when they're structurally sound.
Absolutely. Renovation work often disturbs walls that haven't been opened in decades. Finding mold during a renovation — rather than discovering it after new drywall has been installed — saves significant time and money. A pre-renovation assessment is one of the best investments you can make before starting any significant work.
