You shouldn't need eight vendors to maintain one building.
Most facility directors are managing a painter, a drywall contractor, an electrician, a roofer, a paver, and a handyman — each with separate certificates, invoices, scheduling calls, and excuses when something slips.
Gemstar handles all of it. We hold the trade relationships, verify every subcontractor’s licensing and insurance, schedule around your operations, and give you one person to call.
One contract. One certificate of insurance. One invoice. One phone number.
Estimates back fast
You can’t plan around a two-week turnaround. We walk the scope, price it, and put it in writing while your timeline is still intact.
We answer, and we write it down
Calls and emails get an answer right away. Every scope, change, and decision is documented, so nothing rests on what someone remembers three months later.
