About this company
BioSweep Southeast operates out of Ridgeville, SC and serves the greater Charleston area. They hold a BIOSWEEP franchise license, which gives them access to a hydrogen peroxide gas system that treats mold and odors at a molecular level without chemical residue. The company is veteran-owned and run by founder Michael G. Jager, who launched the business in 2009.
The hydrogen peroxide gas technology is the main differentiator. Where most remediation companies rely on antimicrobial sprays and HEPA filtration alone, BioSweep adds a multi-phase dry gas treatment that targets airborne and surface-level contaminants. They also handle the full rebuild in-house rather than subcontracting it, and they produce Xactimate estimates for insurance claims. They offer a 1-year warranty on rebuild work.
Jager started the company after discovering BIOSWEEP technology and recognizing demand in the Charleston market, where humidity and coastal weather create persistent moisture problems. The company has grown from odor removal into full-service restoration, adding water damage, fire damage, lead abatement, crawl space encapsulation, and biohazard cleanup. They hold IICRC, SC DHEC, and EPA certifications and maintain an A+ BBB rating.
4.9 stars across 94 Google reviews is unusually strong. Zero negative reviews have appeared in the last 18 months. The volume is modest but the consistency is notable for a restoration company, where even good operators typically pick up a few complaints from the stress of insurance claims and water emergencies.

Review consensus
Rebecca draws the most frequent praise across reviews — reviewers consistently name her as responsive, organized, and communicative throughout the project lifecycle. Mike Jager (owner) gets repeated credit for answering calls early in the morning, showing up personally to assess jobs, and sending daily progress photos. Multiple reviewers mention the company arriving when scheduled and delivering what was promised. Repeat business is a recurring theme — several reviewers mention hiring BioSweep two or three times. A Local Guide reviewer (Matt) specifically credited one treatment with fixing air quality issues after visible mold on walls. Gray Moore noted that BioSweep succeeded where a previous mold remediation company had failed.
0 found across 94 total reviews at 4.9★. No 1-star reviews have appeared in the last 18 months. The review record across all 94 reviews at 4.9 stars shows no recent complaints to analyze.
The review profile shows an unusual concentration of 5-star ratings with almost no variation. Several clusters of reviews appear on the same dates (October 13-16, 2025 and December 12, 2023), which could reflect a review solicitation campaign after completed projects. This does not mean the reviews are inauthentic, but the timing pattern is worth noting. Repeat reviewers like Terrill Gant (who reviewed twice) and multiple real estate professionals suggest a referral-driven client base.
Rebecca C. (office coordinator/administrative assistant — consistently positive, most-mentioned staff member across all reviews), Mike Jager / Michael Jager (owner/founder/project manager — positive, praised for personal involvement and responsiveness), Matt (crew/project lead — positive, praised by Carolie Lenoir for going above and beyond), Gabriella (office staff — positive, mentioned by pamela russo for answering questions), Sajjad (technician — positive, mentioned for duct cleaning work), Mike Y. (project manager — positive, praised by Terrill Gant for professionalism)
This is a strong pick for Charleston-area mold and water damage work if you value direct communication with the owner and a single company handling testing through rebuild. Ask for third-party post-remediation clearance testing rather than relying on their in-house results. If you call, you will likely talk to Rebecca first — reviewers universally describe that as a good experience.
Keep in mind
- BioSweep does both air quality testing and remediation, which creates a financial incentive to find problems they can then fix. Consider getting an independent test before committing to remediation work.
- The office is in Ridgeville, about 40 miles northwest of downtown Charleston. Response times to the outer edges of their service area may vary.
- Their hydrogen peroxide gas treatment is a franchise technology, not something they developed. The effectiveness claims come from the franchisor. Ask for post-remediation clearance testing by a third party.
- Hours are limited: Monday-Friday 8 AM to 4 PM, Saturday 8 AM to noon, closed Sunday. Emergency response outside those hours depends on reaching Mike directly.
- With 94 reviews and no recent negatives, the review profile is unusually clean. That could reflect genuinely strong operations, but the sample is small enough that a few bad experiences may simply not have been posted.
