Provider snapshot
What this listing says
Columbia homeowners dealing with a mold problem tied to water damage, since Biotek handles both under one roof and backs its Biostatic coating work with a 30-year product warranty.
Best for
- Columbia-area homeowners who want one company to diagnose and remediate a mold problem, rather than coordinating between a separate inspector and remediation crew.
- Water damage emergencies, since Biotek advertises 24/7 response and uses thermal imaging to locate moisture before drywall gets torn out unnecessarily.
- Property owners who want a written product warranty on mold treatment, since Biotek backs its Biostatic coating application with a 30-year warranty.
- Homeowners outside Columbia proper, since the company also lists coverage in Lexington, Cayce, Forest Acres, and several other Midlands communities.
About this company
Biotek Environmental is a water damage and mold remediation company based at 534 St Andrews Rd in Columbia, SC, operating since 2007 and also covering Greenville, Spartanburg, Aiken, and other parts of South Carolina, plus parts of North Carolina and Georgia. The company handles both the diagnosis and the cleanup of mold problems, along with water damage restoration, fire restoration, and sanitization.
Biotek's mold remediation process centers on what it calls oxidative remediation, chemistry applied in liquid form under pressure that it says reaches into porous surfaces, cracks, and crevices. The company follows that up with Biostatic coatings, an EPA-registered antimicrobial inhibitor it backs with a 30-year product warranty, plus a 1-year workmanship warranty on the work itself. For water damage jobs, the company uses thermal imaging cameras to locate hidden moisture and dehumidification equipment to dry out affected areas. The website states the company follows IICRC standards.
Owner Ancel Hamilton is named repeatedly in reviews going back to 2016, described by reviewers as personally inspecting jobs behind his own staff. The company has been under the same ownership and doing business in the Columbia area since 2007.

Review consensus
Reviewers consistently name owner Ancel Hamilton for personally inspecting jobs and being responsive, along with technicians Ted and Tyler for showing up on time and walking customers through the process. Multiple reviewers describe fast response on emergency water damage calls, including one describing help arriving within an hour of a leak in a vacant listing and another describing a same-day response to a burst pipe on Christmas Eve. Several reviewers specifically credit the company with being honest about the scope of work needed rather than upselling, including one who says a technician diagnosed a problem over the phone and told them they could fix it themselves.
1 found across 35 total reviews at 3.9★. The single 1-star review in the last 18 months, from Tasha Robinson (March 2026), contains no detail beyond "Take my advice and RUN!!!!" There's no owner response and no specifics about what happened, so there's nothing here to assess beyond the rating itself.
Ancel Hamilton (owner — praised repeatedly for personal involvement and honesty), Ted (technician — praised for detailed, step-by-step inspections), Tyler (technician — praised for knowledge and follow-through), Ryan (staff — praised in one review for coordinating response), Paul (technician — praised for fast on-site response), Thomas (technician — praised for professionalism)
The reviews here skew heavily positive and span nearly a decade, with the owner personally named as involved in jobs from 2016 through 2026. The one negative review lacks any detail, so it shouldn't weigh heavily in your decision. Ask for Ancel, Ted, or Tyler by name if you want the technicians reviewers single out most often.
Keep in mind
- Biotek both tests for mold and performs the remediation work, so a finding of mold from their inspection is also a sales lead for their own remediation services. Ask whether you can get a second opinion before authorizing remediation work.
- The company's service area claims are broad, spanning Columbia, Greenville, Spartanburg, Charlotte NC, and Augusta GA. Confirm response times and crew availability for your specific address rather than assuming the same 24/7 turnaround applies everywhere.
- The company's website leans heavily on the safety case for its own chemistry over competing methods; weigh that against independent guidance if you're comparing remediation approaches.
- Only one 1-star review exists in the last 18 months and it contains no specifics about what went wrong, so there isn't enough detail here to know if it reflects a real service failure or an isolated incident.
