What this listing says
Capital District homeowners with attic mold who want an owner-operator with a 10-year transferable warranty and NY mold remediation license.
Best for
- Saratoga County and Capital District homeowners dealing with attic mold from poor ventilation or venting issues.
- Buyers or sellers who need mold remediation with a transferable warranty that adds value to a real estate transaction.
- Homeowners who want the owner on-site doing the work rather than a crew dispatched by a franchise.
- Basement mold situations where dehumidification and moisture source correction are needed alongside removal.
About this company
Advantage Service Group is a Ballston Lake, NY mold remediation company run by Eric Katz. They hold a New York mold remediation license (#MR00385) and a Florida license (#MRSR4595), though their active service area is Saratoga County and the Capital District. The company focuses on residential attic and basement mold, and Eric personally handles most jobs.
What stands out is the EnviroShield product, which they apply as an authorized applicator. It comes with a 10-year transferable warranty — meaning if you sell your home, the warranty follows the property. That is unusual in this market, where most companies offer little or no post-remediation coverage. Their services page describes containment with negative air pressure, HEPA air scrubbers, and antimicrobial surface treatment. They also install ventilation improvements and dehumidification solutions to address the moisture source.
Eric Katz appears to be the sole or primary operator, often working with a team member named Mike. Multiple reviewers going back to 2010 mention Eric by name, and several note he completed attic jobs in a single day. The contact email (EricKatz@AdvantageServiceGroup.net) confirms he is the owner.
4.9 stars across 33 Google reviews is a strong rating. The review volume is modest, but the consistency over more than a decade suggests steady, reputation-driven work rather than high-volume marketing.

Review consensus
Eric Katz is mentioned by name in the vast majority of reviews. Reviewers consistently highlight his honesty — Kelly Flynn's review describes Eric telling her the problem was small enough to fix herself rather than upselling a job. Multiple reviewers praise same-day completion for attic mold work. Timeliness, clear communication, and fair pricing are recurring themes. Amber Wilde, a Local Guide with 166 reviews, liked working with them enough to hire them for a second job. Several reviewers mention Eric explaining the root cause (ventilation, venting) and fixing it, not just removing visible mold.
1 found across 33 total reviews at 4.9★. 1 found across 33 total reviews at 4.9 stars. Evan ONeil (Local Guide, 14 reviews) posted a 1-star review in August 2025 claiming the company damaged a section of roof shingles during a dehumidifier fan installation and tried to conceal it with caulking. He says he discovered it two years after the work and that the job cost $5,000. The owner responded that there is no record of any interaction with this reviewer and invited contact to resolve the situation. This is a single complaint with a disputed factual basis — the owner's denial and the reviewer's two-year delay in discovering the issue make it hard to assess.
The review history spans over a decade (2010 to 2026), which is unusual for a small mold company. The consistency of praise for Eric personally suggests this is a stable owner-operator business rather than a company that has cycled through staff. The one negative review is disputed — the owner claims no record of the reviewer — and no other complaints share a similar theme. The owner responded to that sole negative review, and the response engaged with specifics rather than using a template.
Eric Katz (owner/operator — praised extensively across reviews for honesty, clear communication, same-day work, and fair pricing). Mike (team member — mentioned by Eric McMahon, Neil Rosenthal, and Sharon Cupoli as working alongside Eric on attic jobs).
With 33 reviews at 4.9 stars and one disputed negative, this is a low-risk hire for attic or basement mold in the Capital District. Ask for Eric by name — he is the operation. Get an independent mold inspection first to address the conflict of interest, and if roof work is involved, inspect the exterior within a few weeks of completion.
Keep in mind
- They do both mold inspection and remediation, which is a conflict of interest. The same company that tells you how much mold you have also profits from removing it. Ask for an independent inspection or get a second opinion on the scope of work.
- This is a small operation. If Eric is booked, your timeline depends on his availability. Multiple reviewers mention quick scheduling, but that may vary seasonally.
- The website claims they serve 'all of Saratoga County and the Capital District,' which covers a wide area. Confirm they will come to your specific location without extra travel charges.
- One reviewer reported roof shingle damage from a dehumidifier fan installation that was not discovered until two years later. If roof work is involved, inspect the exterior promptly after completion.
