Wildlife Exclusion & Damage Repair for Attics, Rooflines & Crawlspaces

What Is Wildlife Exclusion & Damage Repair?

Wildlife exclusion is the step where we stop being “pest control” and start being carpenters and building detectives. The goal is simple: no more easy entry points for the species that just caused the problem – and no fresh invitations for the next one.

On a typical job, trapping and removal take care of:

• Raccoons nesting in attics or chimneys
• Skunks denning under porches and foundations
• Opossums in crawlspaces or wall voids
• Rats and mice chewing into attics and garages
• Squirrels in roof eaves
• Bats using tiny roof and vent gaps
• Pigeons and small birds on ledges and beams

Exclusion and damage repair handle the rest:

• Closing carpenter gaps in roof eaves and transitions.
• Screening and reinforcing attic vents, gable vents and crawl vents.
• Framing and building new access doors that actually lock and seal.
• Installing dig-proof bases and one-way doors where needed.
• Repairing chewed wood, fascia, soffits and siding.

If there’s heavy contamination from droppings and urine, we pair this work with attic cleaning and crawlspace cleaning so you’re not left with a “sealed-in” mess.

Common Entry Points We Find on Southern California Homes

After hundreds of roofs, attics and crawlspaces, the patterns repeat. Most wildlife doesn’t chew brand-new holes first – it finds shortcuts the builders left and weaknesses that time created.

Typical Entry Points

• Gaps where rooflines meet walls on room additions and garages.
• Open soffits and carpenter gaps at roof eaves.
• Loose, missing or warped attic vent screens.
• Chewed corners of fascia boards and roof trim.
• Openings around utility lines, pipes and A/C penetrations.
• Damaged crawlspace doors and vents with soil dug out underneath.
• Gaps at garage door corners and side jambs.

Different species exploit different weak spots:

• Rats & mice: ½-inch gaps along pipes, stucco cracks and garage door seals.
• Raccoons & skunks: Rotten wood, loose screens and easy-to-dig soil under concrete.
• Squirrels: Open soffits, roof edges and chewed corners on fascia.
• Bats & small birds: Tiny gaps in vents, ridge caps and tile-to-fascia lines.

The point of exclusion is not to build a fortress – it’s to close the real travel routes animals are using, with materials that match the structure and hold up over time.

Our Exclusion & Damage Repair Process

We don’t guess from the driveway or slap metal on the first hole we see. Every exclusion job follows a process:

1. Full Exterior & Interior Inspection

• Walk the entire exterior: roof edges, eaves, vents, crawlspace, garage, additions.
• Inspect the attic and, when needed, crawlspace and subfloor framing.
• Document active and potential entry points with photos.

2. Trapping, One-Way Devices or Eviction (If Needed)

Depending on the species and situation, we may:

• Set traps for raccoons, skunks, opossums, rats and squirrels.
• Use one-way doors and baby-safe eviction for raccoons, bats and some attic jobs.
• Coordinate timing around maternity seasons so we’re not sealing in young animals.

3. Exclusion Plan & Written Estimate

• List each repair point and what needs to be done – not just “seal house.”
• Specify materials (gauge of metal, mesh type, wood replacement, concrete, etc.).
• Outline any recommended attic or crawlspace cleaning and sanitizing.

4. Repairs & Seal-Up Work

• Perform carpentry, framing and metal work to close entry points.
• Install vent screening, hardware cloth, L-footers and dig barriers.
• Make repairs look clean and intentional, not like random patches.

5. Final Check, Photos & Warranty Options

• Re-walk the structure and confirm all listed items are completed.
• Take after-photos of key repairs for your records.
• Explain warranty options and realistic limits (no one can wildlife-proof raw canyon).

The result: trapping handles the animals that are there now. Exclusion and repair keeps the next wave from using the same weak spots.

Attic & Roofline Exclusion – Eaves, Soffits & Tile Gaps

Attics are prime real estate for raccoons, squirrels, rats, mice, bats and birds. Most get in high, at roof level, where you don’t see the damage from the ground.

Roof & Eave Work We Commonly Do

• Rebuilding or reinforcing chewed fascia and roof edges.
• Closing “carpenter gaps” where fascia meets stucco or siding.
• Screening and framing around gable vents, dormer vents and ridge vents.
• Blocking tile-to-fascia gaps animals are using as highways.
• Sealing gaps where roofs from additions meet the original house.

On bat jobs, this ties directly into bat removal & exclusion – we use one-way devices on active exits and permanently seal all secondary gaps once the bats are out.

On heavy rat and mouse infestations, roofline sealing is paired with rodent control and, when needed, attic sanitation and insulation replacement.

Crawlspace & Foundation Exclusion – Digging, Voids & Access Doors

Crawlspaces are the hidden freeway for skunks, opossums, raccoons, rats and even non-venomous snakes. If the perimeter is wide open, they can move under most of the house unseen.

Common Crawlspace Problems

• Rotten or missing crawlspace doors that don’t actually latch.
• Block vents with rusted screens and soil dug out underneath.
• Open stem-wall gaps at garages, additions and old repairs.
• Voids under slabs, steps and patios animals use as den sites.

What Our Exclusion Work Looks Like

• Build solid, framed crawlspace doors with proper hinges and locks.
• Install new vent screens in chew-resistant metal mesh.
• Add concrete or mortar curbs and L-footers where animals have been digging.
• Seal utility penetrations and open joints in foundation walls.

After years of animals in a crawlspace, you may also need crawlspace cleaning and decontamination to get rid of droppings, urine, nesting debris and odors pulled into living space.

Vents, Doors, Garages & Add-Ons – Closing the “Easy” Gaps

Not every entry point is dramatic. A lot of wildlife uses the same little gaps you and your contractor stopped seeing years ago.

Vents & Utility Openings

• Dryer vents and exhaust vents with broken or missing covers.
• Gaps around A/C lines, hose bibs and electrical penetrations.
• Open chase spaces around chimneys and flues.

Garage & Door Areas

• Daylight visible at garage door corners and bottom seals.
• Side doors with gaps under thresholds or warped jambs.
• Storage areas where animals can slip from garage to attic.

Room Additions & Older Repairs

• Old add-ons where roofs meet walls without proper flashing.
• Repairs done with thin screen or wood that animals easily defeat.

This is where wildlife exclusion overlaps with general building science. We’re not there to renovate your whole house – we’re there to seal the shell so wildlife can’t treat it like a motel.

Materials, Craftsmanship & Photo Documentation

The materials matter. We don’t trust the cheapest, thinnest hardware store options to stand up to raccoons or a determined rat population.

What We Use (Job-Dependent)

• Heavy-gauge galvanized or stainless steel mesh for vents and gaps.
• Exterior-grade lumber and trim for doors, fascia and framing repairs.
• Concrete, mortar or masonry patch for dig-proof curbs and footers.
• High-quality sealants and fasteners rated for exterior use.

We also document work:

• Before-and-after photos of key entry points and repairs.
• Notes about what species the work is designed to stop.
• Photos that can help with insurance conversations on certain jobs.

If you want this page to rank, it also helps that exclusion, damage repair, attic cleaning and crawlspace sanitation are clearly explained for homeowners and property managers looking for real solutions, not quick sprays.

Pricing, Warranty & Realistic Expectations

Every structure is different. A small single-story house with one chewed corner is not the same as a large multi-level home with years of raccoon, rodent and pigeon activity.

What Drives Exclusion & Repair Costs

• Number and location of entry points (ground level vs. roofline).
• Height, pitch and accessibility of roofs and eaves.
• Extent of wood damage, rot or prior bad repairs.
• Whether attic or crawlspace cleaning is needed.
• Species involved – rats vs. raccoons vs. bats vs. birds.

Warranty & Limitations

• Warranty is tied to the specific repairs and materials we install.
• We can’t guarantee “no wildlife ever” in an entire canyon or open-space area.
• We can stand behind properly built exclusion work on the points we seal.

During your estimate, we’ll explain what is covered, what isn’t, and what ongoing maintenance – if any – makes sense for your property.

Exclusion & Damage Repair FAQ

What’s the difference between trapping and exclusion?

Trapping removes the animals that are there today. Exclusion and damage repair close the structure so the next wave of wildlife can’t use the same entry points. Without exclusion, you’re basically running a revolving door.

Do I really need repairs if the animals are gone?

If there are open gaps, yes. Wildlife doesn’t care that you “fixed it” last month – if the hole is still there, new animals will eventually find it. Exclusion is what turns a short-term fix into a long-term solution.

Can you wildlife-proof my whole house?

We can’t control every bird that lands on the roof or coyote that walks down the street, but we can seal the realistic entry points into attics, crawlspaces and walls. On open-space or canyon lots, we’ll be honest about what’s possible and what isn’t.

Do you work with my roofer, contractor or HOA?

Yes. On many jobs we coordinate with roofers, property managers and HOAs so exclusion and damage repair fits with ongoing maintenance and future projects. We can also provide photos and notes for your records.

Is this the same as “pest control” seal-up?

Most general pest control seal-ups are designed around insects and basic rodents. Our work is built around larger wildlife and long-term pressure – raccoons, skunks, opossums, squirrels, bats, birds and serious rodent populations. The materials and carpentry reflect that.
