Atlanta homeowners live under one of the densest tree canopies of any major U.S. city, and while that canopy is beautiful, it creates a direct highway for squirrels, raccoons, and rats into residential attics. Combine year-round wildlife pressure with Atlanta's humid subtropical climate — where summer humidity regularly exceeds 80 percent and afternoon thunderstorms dump moisture that seeps into every vulnerable joint — and you get attics that face a constant assault from both animals and water. Mold thrives in these conditions. Insulation saturated by condensation or storm leaks loses its thermal value entirely and becomes a substrate for biological growth that can affect air quality throughout the home. Finding a company that understands Atlanta's specific combination of wildlife, moisture, and heat isn't optional — it's essential for protecting both your home and your family's health.
There are 15 attic cleaning companies in Atlanta with an average rating of 4.9 stars.How We Chose These Companies
We evaluated attic cleaning and insulation companies serving the greater Atlanta metropolitan area based on objective criteria. Google review ratings were the primary ranking factor — every company on this list holds a 4.9-star rating or higher. We weighted review volume heavily, as more verified reviews provide a more reliable indicator of consistent quality over time. We also assessed the range of services offered, with preference given to companies that address Atlanta's specific moisture, wildlife, and mold challenges rather than offering attic work as a secondary service. All five companies are currently active and serving the metro Atlanta area.
1. Estes Services — The Dominant Market Leader
“Without a doubt, Tristan is one of the most professional technicians we’ve ever worked with.

— Walter Strother
Estes Services stands in a category of its own in the Atlanta market. With 4,641 Google reviews and a 4.9-star rating, they've built one of the largest verified track records of any home services company in the metro — not just in the attic category, but across the entire home services industry. That kind of volume means their crews have worked in virtually every type of Atlanta home, from the brick ranches of Decatur to the newer construction in Alpharetta and the historic bungalows of Grant Park. Their insulation removal service addresses the foundational need most Atlanta attics have: getting old, degraded, or contaminated material out so fresh insulation can perform at its rated R-value. The advantage of a company at Estes's scale is infrastructure — they have the equipment, crew depth, and scheduling capacity to handle projects efficiently even during peak demand periods when smaller companies are booked out for weeks. For homeowners who prioritize reliability, proven track record, and the confidence that comes from a company that has served thousands of Atlanta homes, Estes is the safest choice on this list.
2. Environmental Services Of America — Mold and Restoration Specialists
1650 Marietta Blvd NW Suite E14, Atlanta, GA 30318
“Fantastic experience working with this team on my personal property. They assisted me through every step of the process and ensured a smooth transition through close out of the abatement project. I highly recommend them to anyone needing assistance in this specialized field.”
— Brock Railey
Environmental Services Of America brings a service profile that directly addresses Atlanta's most serious attic problems: mold remediation, general cleaning, and full attic restoration. With 232 reviews and a 4.9-star rating, they've established themselves as the go-to company for homeowners dealing with the kind of compounding damage that Atlanta's climate produces — moisture intrusion that leads to mold growth, which compromises insulation integrity, which then attracts pests looking to nest in damp organic material. Their mold remediation capability is a genuine differentiator in the Atlanta market, where humidity-driven mold growth is one of the most common attic problems homeowners face. Proper mold remediation requires containment protocols, HEPA air filtration, antimicrobial treatment, and verification testing — steps that most insulation-only companies are not equipped to perform. Environmental Services Of America handles the full scope, from initial assessment through remediation, cleaning, and restoration to a clean, functional attic space. For detailed information on mold cleanup, see our attic mold remediation guide.

4. Atlanta's Best Insulation — Local Reputation Leader
3411 Pierce Dr Suite W1, Atlanta, GA 30341
“I was taking care of getting an attic insulated for a friend who is selling a house and not in town. I am in the construction business but don't usually insulate and don't have time. I scheduled 4 quotes and Grant the owner was the most knowledgeable, professional and gave me the confidence to recommend him to my friend. Not only that, his prices were so much lower, I was able to suggest a couple needed options the others didn't even have or think of and still be well below the others. It is up to her to decide to proceed at this point but if she does I will update after the work is completed.”
— paul kitchen
Atlanta's Best Insulation lives up to its name with 107 reviews and a 4.9-star rating that reflects consistently strong execution across the metro area. Their insulation removal focus addresses the core need driving most Atlanta attic projects: old, moisture-compromised insulation that has lost its effectiveness and may be harboring mold or pest contamination beneath the surface. What makes Atlanta's Best stand out is the quality signal embedded in their review profile — maintaining a 4.9 rating across 107 reviews requires that virtually every customer walks away satisfied, which speaks to both the quality of their work and their communication throughout the project. Atlanta's humid climate means insulation degrades faster than in drier markets, and homeowners who haven't had their attic assessed in five or more years are often surprised by how much performance their current insulation has lost. Atlanta's Best Insulation provides the kind of thorough assessment and clean removal that sets the stage for a proper reinstallation.
5. Winners Spray Foam Insulation — Spray Foam Specialists
“💃🏾💃🏾💃🏾💃🏾💃🏾💃🏾”
— Janitor Jones
Winners Spray Foam Insulation rounds out this list with 47 reviews, a 4.9-star rating, and a specialization in spray foam that represents one of the most effective insulation solutions for Atlanta's humid climate. Spray foam insulation creates an air-sealed barrier that traditional blown-in materials cannot match — it fills gaps, cracks, and irregular surfaces while simultaneously acting as both insulation and vapor barrier. In a city where humidity-driven condensation is a primary cause of attic mold and insulation failure, that dual functionality is a meaningful upgrade over conventional approaches. While spray foam costs more per square foot than blown-in fiberglass or cellulose, the energy savings and moisture prevention benefits often make it the more cost-effective choice over a 10-to-15-year window in Atlanta's climate. Winners' focused expertise in this specific material means their installation technique — critical for spray foam, where proper thickness and application temperature directly affect performance — is backed by genuine specialization rather than general-contractor familiarity.

What to Look For in an Atlanta Attic Cleaning Company
Atlanta's climate creates a specific set of demands that not every attic company is equipped to handle. When evaluating providers, prioritize these factors.
Wildlife exclusion experience. Any company working in Atlanta attics should be able to identify and seal common wildlife entry points — ridge vent gaps, soffit intersections, gable vent screens, and plumbing stack penetrations. Squirrels, raccoons, and roof rats are persistent problems across metro Atlanta, and a company that removes contaminated insulation without sealing the entry points is guaranteeing a repeat visit. Ask specifically what exclusion methods they use and whether they offer warranties on their sealing work.
Mold identification capability. Atlanta's humidity means mold is always a possibility in attic spaces, especially in homes with inadequate ventilation or bathroom fans that vent into the attic rather than to the exterior. The company should be able to identify visible mold growth and know when a project requires remediation-level treatment versus standard cleaning. Companies whose technicians hold mold assessment certifications provide an added layer of confidence.
Ventilation assessment. Proper attic ventilation is the first line of defense against moisture buildup in Atlanta's humid subtropical climate. A quality attic company should assess your existing soffit, ridge, and gable ventilation as part of any insulation project and recommend improvements if the current system is inadequate. Inadequate ventilation is one of the most common root causes of recurring attic moisture problems in Atlanta homes.
Average Costs in Atlanta
The Atlanta metro offers competitive pricing for attic services, with a healthy number of providers keeping rates reasonable. Here are typical cost ranges for 2026:
| Service | Estimated Cost Range |
|---|---|
| Basic attic cleaning | $200–$450 |
| Insulation removal | $1,000–$2,200 |
| Insulation installation (blown-in) | $1,200–$2,800 |
| Spray foam insulation | $2,500–$6,000 |
| Rodent/wildlife cleanup | $500–$1,800 |
| Mold remediation | $1,500–$5,000 |
| Full attic restoration | $3,000–$7,000 |
These ranges vary based on attic size, accessibility, contamination type and severity, and whether wildlife exclusion work is included. Older homes in neighborhoods like Decatur, East Atlanta, and Midtown — where housing stock dates to the early and mid-20th century — often require more labor-intensive work due to complex rooflines and limited attic access. For a comprehensive pricing breakdown, see our full attic cleaning cost guide.
Frequently Asked Questions
Why are squirrels and raccoons such a persistent problem in Atlanta attics?
Atlanta sits beneath one of the densest urban tree canopies in the United States, with mature oaks, pines, and pecans providing direct routes from trees to rooflines across virtually every residential neighborhood. Squirrels and raccoons exploit this access with remarkable consistency — they can enter through gaps as small as two inches at ridge vents, soffit intersections, and where tree branches contact the roof surface. Once inside, they nest in insulation, chew electrical wiring, and contaminate the attic space with droppings and urine. The problem is year-round but intensifies in fall and winter as animals seek shelter from colder temperatures. Effective prevention requires both professional exclusion work to seal entry points and regular tree trimming to maintain clearance between branches and the roofline.
How does Atlanta's humidity affect attic insulation?
Atlanta's humid subtropical climate keeps relative humidity above 60 percent for much of the year, which creates persistent moisture conditions inside attic spaces. When warm, humid air contacts cooler roof sheathing or poorly insulated surfaces, condensation forms and saturates the insulation below. Blown-in fiberglass absorbs this moisture and settles, losing both loft and R-value. Cellulose insulation is even more susceptible — it can clump, sag, and lose structural integrity after sustained humidity exposure. In Atlanta's climate, insulation that might last 15 to 20 years in a dry market often needs assessment at the 8-to-12-year mark. Homes with bathroom exhaust fans that vent into the attic rather than to the exterior face accelerated degradation because they're pumping moisture-laden air directly into the insulation layer.
What is the best time of year to schedule attic work in Atlanta?
Late fall through early spring offers the most comfortable working conditions and the easiest scheduling availability. Attic temperatures during Atlanta's summer months can exceed 140 degrees, which limits safe working time and extends project timelines. Scheduling insulation replacement or restoration work between October and March gives crews cooler conditions to work efficiently and ensures your attic is fully upgraded before the cooling season begins in May. That said, if you discover an active wildlife infestation, mold growth, or storm damage, address it immediately regardless of season — these problems compound quickly in Atlanta's humidity and waiting months will substantially increase the scope and cost of remediation.
