American power
plant maintenance,
done right.
Specialty Maintenance Services delivers on-site abrasive blasting, CO₂ dry-ice cleaning, and full-spectrum NDT inspection at gas, coal, and nuclear power plants nationwide. One crew. One contract. 24-hour mobilization.
Three services. One crew on-site.
Every utility outage needs the same trio: surface preparation, contamination-tolerant cleaning, and component inspection. We deliver all three on a single mobilization.
Turbine Sandblasting
On-site abrasive blast cleaning of rotors, casings, valves, blades, and steam paths during planned and forced outages. Aluminum oxide, garnet, steel grit, Black Beauty, glass bead, walnut shell — full media library, full containment, full recovery. We service the complete OEM landscape from GE Frame 7FA to Mitsubishi M501J.
Explore turbine sandblastingCO₂ Dry Ice Blasting
Non-abrasive, zero-secondary-waste cleaning for energized components, generator windings, controls cabinets, and any surface where contamination tolerance is critical. The only true zero-residue cleaning method.
Explore CO₂ blastingNDT & NDE Inspection
Liquid dye penetrant (PT), magnetic particle (MT), ultrasonic (UT), phased-array UT, and eddy-current testing performed by Level II / III techs on the same crew that did the blasting.
Explore NDT servicesWhy clean turbines pay for themselves.
Fouled turbines cost real money. Deposits and scale on rotors and steam paths reduce thermal efficiency, drive up fuel consumption, and shorten the runway between major overhauls. The numbers below are what plant managers and outage planners use to justify the work.
Efficiency & revenue figures based on industry-standard boiler/turbine engineering literature and 600 MW unit economics. Specific numbers vary by plant and operating conditions.

The full vocabulary of turbine maintenance.
Power plant maintenance has a specific language — the same component cleaning gets called by half a dozen names depending on the OEM, the era, and the plant. Whatever you call it, we do it.
If you have ever scoped a turbine outage, you have heard the work called by many names. Turbine sandblasting, turbine blast cleaning, rotor blast clean, hand clean rotor — all of these describe the same core scope: returning a turbine rotor or steam path to a clean, inspectable surface. We perform HP rotor blast, IP rotor blast, and LP rotor blast work on steam turbines from GE, Siemens, Alstom, Toshiba, and MHI, and the corresponding gas turbine work on every major OEM platform from Frame 3 through 9HA.
Beyond the rotors themselves, an outage almost always pulls in adjacent components. Valve blast work on stop valves, control valves, and intercept valves. Steam chest grit blasting and vacuum blast steam chest for tight-tolerance enclosures. Bore blast and hollow blast rotor work for internal passages and cooling holes. Generator coil cleaning and stator winding cleaning using CO₂ dry ice when contamination tolerance is critical. Diaphragm blasting, casing blasting, and compressor blade cleaning on every blade row.
And the methods themselves carry their own language. Contained blast cleaning and tent blasting when the work has to happen on a live turbine deck without contaminating adjacent equipment. HEPA-grade containment for nuclear and combined-cycle environments. Recoverable media abrasive blasting when waste-stream control is part of the spec. Soda blasting and bicarbonate blasting for delicate substrates. Walnut shell blasting for generator field cleaning. Aluminum oxide blasting when you need a defined surface profile for recoating. We carry every one of these in inventory and we know which one your scope of work calls for.
A working crew, not a procurement layer.
Specialty Maintenance Services LLC is an American-owned industrial maintenance contractor based in Brookhaven, Mississippi. We specialize in on-site turbine sandblasting, CO₂ dry-ice blasting, and non-destructive testing for the U.S. power generation industry.
The company was built for the working side of the outage business. Every crew lead came up through the trade. The same person who answers the dispatch phone is the same person who shows up on the turbine deck. There is no procurement layer between you and the people doing the work.
Our service area covers the continental United States, with same-day response across the gulf region and 24-hour mobilization to the rest of CONUS. We bring our own equipment, media, containment systems, and PPE — no waiting on third-party logistics on the critical path of your outage.
From phone call to unit back online.
Outages run on a critical path. Every hour of crew handoff is an hour the unit is not making power. Our process is built around removing those handoffs.
Scope & Quote
Phone call, scope walk-through, and a written quote that names media, containment, NDT scope, and crew size. No surprises on the bid.
Mobilize
Crew, equipment, media, and PPE travel together. ISN, Avetta, Veriforce credentials submitted ahead. On-site within the outage window.
Execute
Containment up, blast in progress, NDT crew working the same surface as soon as it is inspection-ready. One mobilization, three scopes.
Demob & Report
Full media recovery, surface verification, NDT findings package, and a clean turbine deck. Unit returned to the OEM team for closure.
Real units. Real outage windows.
Selected outage work across our service footprint. Specific plant names withheld under standard utility NDA terms — full references available upon request from procurement.
Combined-Cycle Major Inspection
Frame 7FA gas turbine and HRSG section. Aluminum oxide media on rotor and stator path, walnut shell on generator end-windings, full HEPA containment on the turbine deck.
Generator Coil & Stator Cleaning
Dry-ice blasting on a hydrogen-cooled generator stator and field winding during a 7-day forced outage. Zero secondary waste, no shipping of components, generator returned to test inside the window.
Frame 7FA Forced Outage
24-hour mobilization to a Frame 7FA gas turbine. Bore blasting on rotor, PT and PAUT on first-stage blades, full inspection package returned to plant engineering inside 72 hours.
Where the work is, we are.
Top 15 states by installed thermal capacity (gas, coal, petroleum, biomass, nuclear). These are the densest turbine maintenance markets in the country, and the priority footprint for our outage crews.

Questions buyers ask before they ask for a bid.
What services do you provide?
Three primary service lines: on-site abrasive sandblasting (turbine and component blast cleaning across the full media library), CO₂ dry-ice blasting (non-abrasive, zero-residue cleaning for energized and contamination-sensitive components), and non-destructive testing (PT, MT, UT, phased-array UT, and eddy-current inspection by Level II / III techs). All three services are delivered by a single crew on a single mobilization — eliminating the idle handoffs that drag outages over their critical path.
Who do you work with?
We serve investor-owned utilities, independent power producers (IPPs), public power and rural electric cooperatives, EPC contractors, and OEM service organizations. From large utility fleets to single-unit municipal plants — if it has a turbine, we work on it.
How fast can you mobilize for an outage?
We mobilize within 24 hours for emergency outages anywhere in the continental United States, with same-day response across our gulf-region coverage zone (Mississippi, Louisiana, Alabama, Texas, and Florida). Equipment, media, and PPE travel together; we do not wait on third-party logistics.
Are you American-owned and operated?
Yes. Specialty Maintenance Services LLC is American-owned and operated, headquartered in Brookhaven, Mississippi. Every crew member is a U.S. employee. The same team that bids your job is the same team on-site when the work happens.
Outage on the books? Let's get to work.
We respond to every quote request inside one business day. Emergency outage line is monitored 24/7 by an American crew based in Brookhaven, Mississippi.
