We’ve cleaned and restored attics with Attic Cleaning & Rodent Proofing in Laguna Niguel since 2016, from the hillside homes above Crown Valley Parkway to the canyon-adjacent properties near Aliso Summit. The combination of warm, dry summers and mature oak and eucalyptus canopies creates conditions where roof rats, squirrels, and mice find easy access through aging fascia boards, unscreened vents, and gaps where tile roofs meet stucco walls. Once inside, they compress insulation, leave biohazardous waste, and create fire risks by gnawing wiring. We don’t just remove the evidence; we seal the entry points, sanitize to hospital-grade standards, and document every step with photos you’ll receive before we leave.

Our crews are background-checked, uniformed, and arrive on schedule. A live person answers our phones 24/7, no voicemail loops. Every job starts with a written price and ends with a Documented Photo Record.

What Our Attic Cleaning & Rodent Proofing Service Includes

Attic Cleanout

An attic cleanout is the complete removal of contaminated insulation, debris, and organic matter that rodents leave behind, including nesting material, food stores, and carcasses. In Aliso Viejo Attic Cleaning & Rodent Proofing and Laguna Niguel, we regularly find that roof rats have packed Owens Corning fiberglass batts into corner nests, reducing R-value by half in those zones. We remove everything with HEPA-contained vacuums and bag it for proper disposal, not your household trash. After cleanout, you’ll see your joist bays and top plates clearly for the first time in years, which lets us identify every air leak and entry point before the next phase begins.

Attic Sanitizing & Decontamination

Attic sanitizing applies EPA-registered disinfectants to all surfaces that contacted rodent urine, feces, or nesting material, eliminating hantavirus, leptospirosis, and salmonella risks. We use a two-step process: enzyme-based breakdown of organic matter followed by hospital-grade disinfectant fogging that penetrates into porous wood and drywall edges. In Laguna Niguel’s warm climate, dried rodent waste becomes friable and airborne when disturbed, so we run negative-air machines during this phase to protect your living space. You’ll receive photos of before-and-after surface readings with a luminometer, showing ATP (organic contamination) reduction to safe levels.

Rodent Proofing & Exclusion

Rodent proofing, also called exclusion, is the physical sealing of every entry point larger than 1/4 inch, the width a young rat needs to squeeze through. We use galvanized steel mesh, copper flashing, and concrete patching on the exterior, plus sealant on interior penetrations, because rodents can gnaw through foam, wood, and vinyl in a single night. In Laguna Niguel and San Juan Capistrano Attic Cleaning & Rodent Proofing areas, we see recurring problems in homes with Spanish tile roofs where broken tiles create gaps at the fascia, and in properties near Laguna Niguel Regional Park where mature trees provide highway access to rooflines. Our exclusion work carries a one-year warranty: if rodents re-enter through any point we sealed, we return at no charge.

Attic Restoration

Attic restoration is the complete rebuild after cleanout and sanitizing, returning your attic to a clean, efficient thermal barrier. We install new insulation to match or exceed original R-value, typically R-38 to R-49 for Laguna Niguel’s climate zone, using materials from Owens Corning, Johns Manville, or GreenFiber depending on your preference and budget. Before any insulation goes in, we complete air sealing of top plates, can lights, and penetrations, because blowing new material over an unsealed attic floor traps conditioned air leaks forever. On every restoration, we provide before-and-after blower-door numbers, a pressurization reading that shows, in one figure, how much air your home was losing before and after the work.

Signs You Need Attic Cleaning & Rodent Proofing Right Now

• Scratching or scurrying sounds after sunset. Roof rats are nocturnal. If you hear movement in ceilings or walls between 10 PM and 4 AM, you have active infestation. In Laguna Niguel’s hillside homes, sound travels through open joist bays and can seem to come from everywhere at once, making professional inspection with a borescope camera the only way to locate nests accurately.
• Urine stains on ceiling drywall or light fixtures. Rodent urine contains ammonia and phosphorescent compounds that show under UV light. We inspect with ultraviolet lamps during our assessment, and we’ve found that Laguna Niguel homes with recessed can lights often show ring-shaped stains where rats traveled along the fixture housing. These stains indicate active pathways and potential electrical hazard from gnawed wiring.
• Insulation that looks flattened, tunneled, or discolored. Healthy insulation maintains loft and uniform color. If your attic insulation looks like someone walked through it in boots, or shows dark trails through the material, that’s rodent runway compression mixed with grease from their fur and urine marking. Compressed insulation loses 30-50% of its thermal performance, which you’ll see in summer cooling bills across Laguna Niguel’s August and September heat peaks.
• Visible droppings in the attic or around exterior vents. Fresh droppings are dark and moist; old ones are gray and crumble to dust. Finding either means entry points remain open. We commonly discover that Laguna Niguel homes built between 1985 and 2005 have unscreened attic vents or deteriorated rubber gaskets around plumbing penetrations, both of which we correct during exclusion.
• Unexplained increase in energy bills or HVAC runtime. When rodents destroy insulation and create open air pathways, your conditioned air escapes faster than the system can replace it. We’ve measured blower-door readings above 5,000 CFM50 in Laguna Niguel attics with severe rodent damage, nearly double what a sealed envelope should read for homes that size. The system runs longer, wears faster, and still can’t maintain setpoint.

Our Attic Cleaning & Rodent Proofing Process - Step by Step

1. 1
   Written estimate with photo documentation. We inspect your attic with a borescope camera and UV light, then walk the exterior to identify every potential entry point. You’ll receive a written price with line-item breakdown, a proposed scope of work, and photos of what we found before anyone lifts a tool. This is Haven Standard Clause 1: flat price, written scope, written warranty before work starts.
2. 2
   Containment and HEPA removal. We seal your attic access and run negative-air machines to protect your living space. All contaminated material is vacuumed with HEPA filtration into sealed bags, then hauled for proper disposal. We document volume removed and disposal receipts.
3. 3
   Sanitizing and decontamination. Surfaces receive enzyme treatment followed by hospital-grade disinfectant fogging. We test with a luminometer to verify ATP reduction to safe levels, typically below 30 RLU (relative light units) on wood surfaces. Photos of readings go into your Documented Photo Record.
4. 4
   Exclusion and air sealing. Every entry point 1/4 inch or larger is sealed with rodent-proof materials: galvanized steel mesh, copper flashing, concrete repair, and specialized sealants. We then air seal top plates, can lights, plumbing and electrical penetrations, and chimney chases. On applicable jobs, we run a blower-door test to measure the improvement.
5. 5
   Restoration and final documentation. New insulation is installed to specified R-value, with material from your chosen manufacturer. We conduct final inspection, provide before-and-after photos, blower-door readings if applicable, and your written warranty. The 365-Day Done Right Promise applies: if it’s not done right, we make it right.
