Safety From Day One

Much of our work happens inside active plants, occupied buildings and government facilities, where a single safety lapse can shut down an operation or put people at risk. For us, safety and compliance are not paperwork filed at the end of a job. They are how we plan and run every project from the start, backed by the licensing, insurance and training our clients require before work begins.

◈ OSHA-Compliant

Our field crews work to OSHA safety training standards, keeping job sites and personnel protected on every project.

◈ Lead-Safe Practices

We follow Lead-Safe work practices on projects involving older structures and lead-based materials.

◈ Licensed & Insured

Capstone Mechanical & General Contractor LLC is a fully licensed and insured contractor in Puerto Rico.

◈ Quality Assurance

We check our work against defined quality standards at each phase, so results hold up under inspection.

We Own The Work

Because we self-perform much of our mechanical, electrical, concrete and specialized work, we keep direct control over how safely it is carried out, rather than relying on outside crews we cannot vouch for. When a project calls for specific compliance documentation, safety reporting or inspection records, we prepare them as part of the job, not once the work is done.
