TSIAC International - Demolition Asbestos & Restoration Removal
Provider snapshot
What this listing says
Charleston-area homeowners dealing with mold in older homes or crawl spaces where asbestos or lead may also be present, since TSIAC handles all three hazards in-house.
Best for
- Charleston Lowcountry homeowners who need crawl space mold remediation, especially in older homes where asbestos or lead may complicate the project.
- Renovation projects that require selective demolition along with mold cleanup -- TSIAC can gut and remediate in one scope of work.
- Property owners dealing with fire or water damage who need both demolition and mold remediation from a single contractor.
- Commercial tenants or general contractors in the Charleston and Myrtle Beach areas who need hazmat-aware demolition on a tight schedule.
About this company
TSIAC International is a Charleston-based demolition and abatement contractor that also does mold remediation. They are primarily a demolition company -- mold removal, crawl space remediation, asbestos abatement, and lead removal are secondary services built around that core. The company is family-owned, run by Andra Basnight, and has been operating for over 15 years. Their address is on East Bay Street in downtown Charleston.
What stands out is the range of hazardous material work under one roof. If your mold project also involves asbestos siding, lead paint, or structural demo, TSIAC can handle all of it without subcontracting. Their mold removal page describes using HEPA filtration, negative air machines, containment, and antimicrobial treatments. They also mention moisture meters and thermal imaging for inspections. The website lists federal government clients (USDA, Coast Guard, Air Force) for asbestos abatement, which signals experience with regulated hazmat work.
TSIAC holds SAM registration (UEI: QM9EL88DMAU7) and NAICS codes covering remediation services and hazardous waste. Their past projects include commercial retail renovations (Chick-fil-A, ALDI, Planet Fitness, Alo Yoga) and government facilities. They serve both the Charleston Lowcountry and Myrtle Beach areas, with location pages listing 30+ cities across South Carolina.
A 4.8-star rating across 60 Google reviews with zero negatives in the last 18 months is notably clean. Most reviews center on demolition and asbestos work rather than mold specifically, so buyers hiring for mold remediation are relying on a track record built in adjacent services.
Services

Core service area covers the Charleston Lowcountry: Summerville, Goose Creek, Mount Pleasant, James Island, Johns Island, Kiawah Island, Seabrook Island, Knightsville, and Moncks Corner.

Location pages list 30+ cities across South Carolina including Greenville, Rock Hill, and Columbia-area towns, which is an extremely broad claim for a family-run operation.
Review consensus
Andra Basnight (owner, also spelled Andre) is named in the majority of reviews. Reviewers consistently highlight three things: he shows up on time or early, he communicates clearly before and during the project, and projects finish ahead of schedule. Multiple commercial clients (Alo Yoga storefront, King St demo, 6,000 sq ft restaurant) note fast turnaround. Harold Gillens from Quintech Solutions praised repeated ACM abatement projects. Residential reviewers mention fair pricing, clean job sites, and flexibility with scope changes. Angela and Miguel are named once for a bathroom demo.
0 found across 60 total reviews at 4.8★. No negative reviews (3 stars or below) appeared in the last 18 months. The single 4-star review from Jacob Hirsch praised the work quality and Andra's communication but did not specify a complaint. With 60 reviews and a 4.8-star average, this is an unusually clean review history.
Nearly every review mentions Andra by name, suggesting he is personally involved in most projects rather than delegating to separate crews. This is a strength for quality control but could become a bottleneck as the company grows. The reviews also skew heavily toward demolition and asbestos -- only a handful reference mold or restoration work, which means the mold remediation side of the business has less public track record to evaluate.
Andra Basnight (owner/operator -- positive across 20+ reviews). Angela (crew member -- positive, named once for bathroom demo). Miguel (crew member -- positive, named once for bathroom demo).
Ask for Andra directly and confirm he will be on-site for your mold project. Since most of their reviewed work is demolition and asbestos, ask for references from recent mold remediation clients specifically. Get an independent mold test before hiring them to remediate -- the conflict of interest matters.
Keep in mind
- TSIAC does both mold testing and mold remediation, which is a conflict of interest. The same company that finds the mold profits from removing it. Ask whether they will accept a third-party test result or recommend an independent inspector.
- Demolition is their primary business. Mold remediation is a newer service line. Most of their 60 Google reviews are for demo and asbestos work, not mold jobs. Ask specifically about mold project experience and volume.
- Their service area claims span 30+ cities across South Carolina, from Charleston to Greenville to Rock Hill. That is a very broad footprint for a single crew. Confirm actual availability and travel charges for locations far from Charleston.
- The website advertises '30% off on all services' and financing -- promotional pricing can sometimes signal flexible quoting. Get a detailed written estimate before committing.
