Rodent Exclusion & Sealing in Henrico County, VA | Henrico Rodent Control Co.

If you're searching for rodent exclusion and sealing near you in Henrico County, VA — closing the entry points that keep allowing rodents back in — this is the service you need. We cover all of Henrico and the Richmond metro.

Why Trapping Alone Doesn't Solve the Problem

Removing the current rodent population treats the symptom. The open entry point is the disease. A house mouse can enter through a gap approximately the diameter of a dime — 1/4 inch. A rat needs only 1/2 inch. Most structures, particularly those built before 1980, have multiple entry opportunities at utility penetrations, foundation interfaces, crawl space vents, and roofline gaps.

Without exclusion, removing one population creates vacancy for the next. In areas with significant outdoor rodent pressure — near wooded lots, creek corridors, or older neighborhoods — that vacancy will be filled. Exclusion is what converts a temporary fix into a permanent one.

Common Entry Points in Henrico County Homes

• Pipe penetrations: Gas lines, water pipes, and drain lines entering the foundation or exterior walls often have gaps left at installation or developed as caulk aged
• Crawl space vents: Older homes use wire mesh that corrodes and fails; some have no mesh at all
• Roofline gaps: Where the fascia meets the soffit, at gable vents, and where the roof deck meets exterior walls at dormers
• HVAC penetrations: Condensate lines, refrigerant lines, and flue pipes are common entry points that are easy to miss
• Foundation cracks: Settling cracks at or below grade, especially at corners
• Door and window gaps: Worn weatherstripping or damaged door sweeps on garage doors are frequent mouse entry points
• Roof vents: Turbine vents and static vents with damaged or missing screens

Materials We Use

Material selection is based on the opening size, location, and the exposure risk:

• Xcluder Fill Fabric / Copper mesh: For small gaps at pipes and penetrations — flexible, rodent-proof, and non-corrosive
• 1/4" galvanized hardware cloth: For crawl space vents, gable vents, and any opening larger than 1/2"
• Metal flashing: For roofline repairs, soffit gaps, and wood-to-structure interfaces where rodents have been gnawing
• Silicone caulk / hydraulic cement: For foundation cracks and small concrete gaps, used in conjunction with mesh where needed
• Door sweeps and weatherstripping: Where gaps at the base of doors are the identified entry point

Exclusion with an Active Infestation

Exclusion on a home with an active infestation requires a specific sequence: treat first (trap and reduce the population), then seal the structure. Sealing while a full population is still active inside can trap rodents in the wall voids, which creates its own problem — entombed rodents decompose, causing odor problems for weeks. In some cases, we can perform partial exclusion (sealing non-active entry points, particularly upper-structure points that haven't been used) in parallel with active trapping on the lower structure. We'll advise on the right sequence for your specific situation based on what the inspection finds.

How Long Does Exclusion Last?

The durability of exclusion work depends on the materials used and the quality of the installation. Hardware cloth (1/4" galvanized) properly secured at crawl space vents is a 15–20+ year installation in Virginia's climate. Copper mesh at pipe penetrations, set with caulk, is similarly durable. Expanding foam alone — which some DIY guides recommend — is not a long-term exclusion material; rodents can chew through it within weeks. We don't use expanding foam as a primary exclusion material; it's used only as filler behind harder mesh materials where needed.

We provide a 12-month warranty against re-entry through our sealed points on all completed exclusion jobs. If we sealed it and a rodent gets through it within the warranty period, we come back and fix it at no additional charge. This warranty doesn't apply to new entry points that were not present or identifiable at the time of exclusion — older homes occasionally develop new gaps as they settle, and those would need to be addressed in a follow-up inspection.

Cost and What That Covers

Exclusion pricing ranges from $300 to $1,200 depending on the number of entry points identified, property size, and material requirements. A straightforward job sealing 3–4 utility penetrations and replacing crawl space vent screens on a mid-sized Henrico home typically runs $350–$550. A larger older home with failing vent systems, multiple roofline gaps, and numerous utility penetrations sits toward the upper end. We provide an itemized quote after inspection — you'll know exactly what you're paying for before work begins. See our pricing page for typical ranges by service component.
