Alpine Group

Alpine Group delivers air duct cleaning, mold remediation, and related indoor air quality services throughout the Indianapolis metro area. Holding a 4.9-star rating derived from 149 client reviews, the company maintains standard weekday operations Monday through Friday from 8 AM to 5 PM. Their service menu extends beyond core duct cleaning to include dryer vent maintenance, full mold inspection and removal, insulation upgrades for attics and crawl spaces, and specialized hoarder cleanup assistance for both residences and commercial properties.

What distinguishes Alpine from competitors is their thorough investigative approach to indoor air quality challenges. Rather than performing a single pass and departing, their technicians trace problems to actual sources, a practice illustrated when a reviewer requested a recheck after another contractor flagged lingering concerns, and their team member physically accessed the attic to verify completion rather than arguing from ground level. The company offers comprehensive commercial services covering office buildings, apartment complexes, and retail properties alongside their residential work.

Client feedback specifically names two technicians, Sam and Mark, who have earned repeat attention for their willingness to answer extensive questions and perform above-and-beyond inspections. One reviewer described Sam taking time to explain the process after a move-in, while Mark later re-examined ductwork at the reviewer's request and personally climbed into the attic to assess conditions. Another client recounted how Mark investigated persistent mold readings that initially appeared alarming, ultimately tracing the source to staging furniture rather than the property itself.
