A house mouse can squeeze through a gap the width of a pencil. Mouse proofing in Savannah means sealing the small gaps that other exclusion work skips — dryer vents, plumbing penetrations, sill plates, garage door corners, utility entries.
Mouse proofing in Savannah is the entry-point sealing work specifically targeting the 6mm (quarter-inch) gaps that house mice use to enter buildings. Mouse-sized gaps are an order of magnitude smaller than what rats use, which means mouse proofing involves more detail work, more individual seal points, and more attention to surfaces other exclusion work skips. Mouse proofing is often the right scope for homes that have had repeat mouse infestations but no rat history. Typical Savannah scope: $400–$1,400 depending on building.
Mouse proofing in Savannah hits a particular failure mode that most homeowners discover only after their second or third winter with mice. The OTC sealing they did themselves after the first infestation addresses the obvious gaps (the visible hole under the kitchen sink, the open spot where the dryer vent comes through the wall) but misses the less-obvious access points: sill-plate gaps along the foundation, plumbing stub-outs in cabinet voids, gaps where the slab meets the framing in newer construction, garage-to-house transitions, dryer-vent flap gaps when the flap isn’t fitted properly.
Savannah housing makes this worse in three specific ways. Historic homes have plaster walls with knob-and-tube remnant penetrations, original sill plates that were never sealed, and gaps where century-old plumbing was retrofitted. 1920s Ardsley Park and Gordonston bungalows have crawl-space entries and sill-plate seams along the long foundation runs. Modern Pooler and Berwick subdivisions have engineered penetrations that look sealed but leave 1/4-inch gaps at every electrical, plumbing, and gas stub-out. All three need mouse-specific attention.
Mouse-sized gaps require closer inspection than rat-sized gaps. We work systematically — interior kitchen and pantry, basement and utility room, exterior perimeter, garage.
Each entry point photographed and located. Mouse proofing typically catches 15–40 individual seal points on a single-family home — far more than rat proofing.
Copper mesh in tight spaces, hardware cloth backed with sealant where larger spans need closing, expanding foam only as backer (not the structural seal), color-matched sealant on visible exterior surfaces.
Methodical work, point by point. Mouse proofing takes more time per square foot of building than rat proofing because the gaps are smaller and more numerous.

Mouse proofing typically costs more than rat-only proofing for the same building because the gap count is higher and the detail work takes longer. The tradeoff is far broader rodent resistance.

A standard single-family home in Savannah typically has 15–40 gaps that mice could use — sill-plate seams, plumbing stub-outs, utility penetrations, dryer vent, garage transitions, foundation-to-siding seams, cabinet penetrations. Most are 1/4 to 1/2 inch, none individually look like a problem, but collectively they’re why mice get in every winter.
Yes — anything sealed against mice also blocks rats. Mouse proofing is the more comprehensive scope. If you only have rat pressure, rat proofing is cheaper; if you face both or want maximum coverage, mouse proofing handles everything.
You can try, and for visible gaps it sometimes works. The challenges are: finding the non-obvious gaps (sill plates, cabinet penetrations, garage transitions), choosing materials that hold up to humidity (steel wool rusts in Savannah, expanding foam degrades), and getting the seal tight enough that mice can’t push through. Many of our customers come to us after a DIY round didn’t hold.
More time-intensive than rat proofing because the gap count is higher. Typical single-family home is one full day — 6–9 hours of detail sealing after the audit. Larger or older homes can stretch to two days.
Initial inspection requires access to the property. Most of the sealing work is exterior plus some interior areas (under-sink cabinets, garage, basement, attic access). You can be home or away during the work itself — your call.
Dryer-vent flaps are a frequent mouse entry point in Savannah, especially on older or weather-degraded vents. We inspect every dryer vent and replace any with damaged or missing flaps. The replacement vent uses a louvered hood that closes when the dryer isn’t running but stays vented when it is.
No. We don’t seal soffit ventilation, foundation vents, or attic ridge venting — those are designed openings the building needs. We seal only the unintended gaps adjacent to those designed openings.
Sealing 6mm-plus gaps has a modest secondary effect on insect entry, but it’s not designed as insect exclusion. Ants and small insects use much smaller pathways than 6mm. If you have insect pressure separate from rodent issues, a general pest-control program is the better scope for that.
Either works. Before winter (October–November) is preventive — you skip the infestation entirely. After a mouse problem (any time of year) is responsive — clearing the population and sealing the entry routes so it doesn’t recur. Most customers we work with are post-problem; some are preventive, especially when buying a new home or after renovation.
