Homeowners assume new construction means no wildlife problems. The reality is that brand new homes often have more entry points than older, well-maintained properties. Here's what builders leave behind — and why it matters.
One of the most common misconceptions we hear from homeowners in Northern Georgia is this: "My house is brand new — there's no way animals can get in." Unfortunately, that assumption is wrong more often than it's right. New construction homes throughout Chatsworth, Dalton, Blue Ridge, Ellijay, and the surrounding areas are some of the most vulnerable properties we inspect.
Why New Construction Homes Have Wildlife Entry Points
Homebuilders focus on building to code, passing inspections, and closing on time. Wildlife exclusion is not part of the building process. Construction gaps, unsealed utility penetrations, and builder-grade vent covers are standard — and they're exactly the kind of vulnerabilities that wildlife exploits.
During the construction process itself, homes sit open for weeks or months. Framing is exposed, roof decking goes on before fascia is finished, and soffits are installed with gaps that never get sealed. Animals begin scouting and entering homes while they're still being built.
The Most Common Entry Points in New Homes
- Construction gaps behind the gutter line — These are among the most common entry points we find. Where the roof decking meets the fascia board behind the gutter, builders frequently leave gaps. Sizes vary — usually 1/2 inch up to 6 to 8 inches at the widest points. Mice need 1/4 inch. Bats need 3/8 inch. These gaps are hidden behind the gutter and invisible from the ground.
- Unsealed utility penetrations — Plumbing stacks, HVAC lines, electrical conduits, and gas lines all pass through the building envelope. These penetrations are rarely sealed in areas like exterior walls where lines lead inside to areas like walls or attics. They create direct pathways from outside into your home.
- Builder-grade gable vents and soffit vents — Gable vents only have bug screen on the inside — never rodent-proof screening. It's super thin and easily entered. Soffit vents use aluminum or plastic panels where the overlaps separate or gap at the ends. Builders tend to leave space. Either way, aluminum or plastic in these areas are always doomed to fail.
- Ridge vents — Ridge vents sit along the very peak of the roof — the tip top. What builders use is a plastic ridge vent that is overlapped by shingles. These plastic vents often warp over time. If the plywood underneath is not perfectly even (which it never is), there's pressure that begins the warping process. Expansion and retraction from heat and cold accelerates it, creating gaps that allow rodents underneath. Squirrels, mice, rats, and raccoons will also chew through these plastic vents — they treat them like chew toys.
- Garage door gaps — New garage door installations frequently leave gaps at the bottom corners and along the weatherstripping that mice and snakes exploit immediately.
- Foundation-to-sill plate gaps — The transition from the concrete foundation to the wood framing above it often has gaps that are invisible from outside but wide open from the crawl space side.
What Wildlife Targets New Construction in Georgia
In Northern Georgia, new construction homes attract a specific set of wildlife. The species depends on the location, the season, and the type of gaps present — but the result is the same: animals find their way in within months of the home being completed.
- Mice and rats — Often the first to find utility penetrations and foundation gaps. They can enter through a gap the size of a dime. Most times they start low — working foundation gaps, utility penetrations at ground level, and garage door seals. If no entry is found low, they go high — accessing the same areas as squirrels along rooflines, gable vents, and ridge vents. Once inside, they contaminate insulation, chew wiring, and reproduce rapidly.
- Squirrels — Squirrels start high and work down. Their typical entry points include rooflines at gutters, returns, gable ends, gable vents, ridge vents, square roof vents, and more depending on the home. They chew through standard builder vent covers and plastic ridge vents easily, establishing nests in attic insulation. Chewed electrical wiring is a serious fire hazard.
- Bats — Always high points only. Think of it like a hang glider — they have to run and fall off a cliff. That's essentially how bats launch. Their wings are longer than their body, so they have to fall before they fly. Can they start from the ground? Yes, but it's difficult due to wingspan. The most common entry areas are gable vents, returns, soffits, ridge vents, rooflines, freeze boards, and other high points on the home.
- Raccoons — Larger gaps in soffits and roof-wall junctions allow raccoons to enter. They're strong enough to pull apart builder-grade materials that weren't designed to resist animal pressure.
- Snakes — Foundation gaps and garage door seals are the entry points. Snakes follow rodent activity — so if mice have found a way in, snakes will follow.
When Should New Homeowners Get an Inspection?
The best time to have a professional wildlife inspection on a new construction home is before you close — or within the first few months of moving in. The longer construction gaps remain unsealed, the more likely wildlife will find and begin using them. By the time you hear noises in the attic or see droppings in the garage, animals are already established.
We recommend a professional 132-point inspection for any new construction home. Our inspection identifies every gap, penetration, and vulnerability that builders leave behind — and we seal them with custom metal work and commercial-grade materials before wildlife finds them first.
New Home Exclusion Is Easier and Less Expensive Than Remediation
Sealing a new home before wildlife establishes is significantly less expensive than removing an infestation, cleaning contaminated insulation, and then performing the exclusion work anyway. Proactive exclusion on new construction typically costs a fraction of what full remediation costs after animals have been living in the attic for months or years.
Don't assume your builder sealed your home against wildlife. They didn't. That's not what they do. A professional wildlife exclusion company identifies and seals the gaps that builders leave behind — and that's exactly what we specialize in.
