Sandblasting for General Contractors

A reliable blast subcontractor that shows up, hits the spec, and coordinates cleanly with your coating crew.

A blast sub that works on your schedule — not ours

General contractors managing construction and renovation projects with structural steel need a blast subcontractor who can fit into the project schedule — not one that creates a scheduling problem. Steel needs to be blasted before coating. Coating needs to follow blasting fast, before flash rust sets in. That sequence works when the sub is reliable, communicative, and can execute without disrupting other trades on site.

Blasting Jack works as a blast subcontractor for GCs on new commercial and industrial construction, building renovation, and infrastructure projects throughout Southeast Michigan. We coordinate directly with your coating contractor on sequencing, we're on-site when we say we'll be there, and we deliver the surface cleanliness and profile the coating spec requires.

For renovation projects in occupied or partially occupied buildings, we handle dust containment and can use vapor/dustless blasting to reduce airborne particles where other trades or building occupants are nearby. We've worked on projects where blasting happened floors away from occupied tenant spaces — it requires planning and the right method, not avoiding the work.

Common blast applications

  • New construction structural steel prep before coating
  • Renovation structural steel — existing building recoating
  • Coordination with coating subcontractors on sequencing
  • Building steel in occupied environments with dust control
  • Parking structure steel prep on maintenance projects
  • Industrial and commercial facility steel — new and renovation

GC blasting subcontract applications

New Construction Steel Prep

New structural steel on commercial and industrial construction projects requires blast prep before protective coating systems are applied. We slot into the construction schedule after steel erection and before coating.

Building Renovation Recoating

Renovation projects involving recoating of existing building structural steel require complete removal of the existing system. We provide blast prep coordinated with the coating contractor on the renovation schedule.

Coordination with Coating Crews

Blasting and coating are a paired sequence. We coordinate directly with the coating contractor on daily production — how much steel gets blasted, when it's ready for primer, and how to avoid flash rust in humid conditions.

Occupied Building Blasting

Renovation in occupied commercial buildings requires dust control and containment. We use vapor blasting in sensitive areas and barrier containment to isolate the work from building occupants and other trades.

Parking Structure Projects

Parking structure restoration projects for GCs involve structural steel blast prep across multiple deck levels with scheduling around occupancy and traffic control requirements.

Industrial Facility Construction

Industrial facility construction and expansion — manufacturing plants, warehouses, processing facilities — requires blast prep on new structural steel, process equipment, and tank installations.

Frequently Asked Questions

Do you work directly as a subcontractor to GCs?

Yes. We sub directly to general contractors on construction and renovation projects. We provide blast prep only — coating is handled by the painting sub or coating contractor you've already engaged.

How do you coordinate with the coating contractor on sequencing?

We work directly with the coating contractor to align daily production. Blasted steel needs to be primed within hours in humid conditions — we plan production quantities so coating follows blast at the right pace to avoid flash rust.

Can you work on a job site where other trades are active?

Yes. We manage containment for the blast work area and coordinate with the site superintendent on access, safety, and sequencing with other trades. We're used to working in active construction environments.

What documentation can you provide for surface prep compliance?

We can document surface cleanliness and anchor profile achieved on the project. For projects requiring SSPC inspection or coating system compliance documentation, we work with the GC and coating contractor to provide what's needed.
