Best for

About this company
A1 Restoration is a family-owned restoration company based in Greenwood, Indiana, run by owner Jeff Hemmer. They handle water damage, mold remediation, fire restoration, roofing, and crawl space encapsulation for both residential and commercial properties. Mold is one piece of a broader restoration operation — they started as a water damage and roofing company and added mold services over time.
Nothing about their mold-specific equipment or methods stands out as unusual. Their website describes standard remediation language — inspection, containment, removal, prevention — without naming specific equipment or techniques. What does stand out is their full-service model: they dry the water, fix the mold, repair the drywall, and replace the roof if needed, all in-house. Multiple reviewers mention competitive pricing compared to other companies they quoted.
Jeff Hemmer has run the company for over 15 years. He answers the phones himself, handles estimates personally, and shows up on emergency calls at 5 AM. Several reviews mention him by name as the point of contact from first call through completion.

Review consensus
Jeff Hemmer draws the most praise — reviewers name him repeatedly for fast response, honest assessments, and competitive pricing. Jaclynn Burns says he arrived within 15 minutes of a middle-of-the-night call. Carol Urbanski says his quote was significantly lower than a competitor and he got equipment in faster. Calvin earns praise from Alexia for arriving within an hour and treating the family with kindness during a difficult cleanup. Brett is mentioned alongside Jeff on a roofing and insurance job. Multiple reviewers highlight that A1 handles the full scope — drying, repairs, mold — without needing a second contractor.
2 found across 25 total reviews at 4.8★. Bobby W (1-star, May 2025) accused A1 of lying about being a family business based in St. Louis. Jeff Hemmer responded with his personal cell number, stated he is the only person who answers the phones, and asked Bobby to reconsider, suggesting a case of mistaken identity. Zach Leitch (3-star, April 2026) had Nate come out for a mold inspection and found him knowledgeable and personable, but Nate ghosted on the follow-up remediation — no reply, no callback. No owner response on that review.
The two negatives point in different directions. The 1-star looks like a case of mistaken identity — the owner's detailed, personal response is credible. The 3-star is more concerning: a customer ready to spend money was simply never called back. With Jeff handling most calls personally, the gap may reflect what happens when someone else (Nate) owns the follow-up. Owner response rate on negatives is 50% — Jeff responded to the one that directly challenged his reputation but not to the ghosting complaint.
Jeff Hemmer (owner — praised repeatedly for fast response, honest assessments, competitive pricing, and personal involvement). Calvin (field team lead — praised for speed and kindness during emergency cleanup). Brett (field team — mentioned positively alongside Jeff on roofing/insurance work). Nate (field staff — praised for knowledge during inspection but criticized for ghosting a customer on follow-up).
Ask for Jeff directly when you call. He runs estimates, answers the phone, and shows up on emergencies — and most of the positive reviews tie back to his personal involvement. If someone else handles your job, pin down a written schedule and confirm who your point of contact will be. The Zach Leitch experience suggests follow-through can slip when Jeff is not the one managing it.
Keep in mind
- A1 does both mold testing and mold remediation. That creates a conflict of interest — the same company that tells you mold exists also profits from removing it. Consider getting an independent mold test before committing to their remediation work.
- One reviewer was ghosted after the initial mold inspection — Nate came out and was knowledgeable, but never followed up for the remediation. If you schedule work, get a written timeline and confirmation.
- With only 25 Google reviews, the sample is small. The 4.8-star rating looks strong, but a few bad experiences could shift it meaningfully.
