Do you use your own employees or subcontractors?

Keystone manages a vetted network of specialized vendors. We don't deploy our own crews — we focus on vendor selection, supervision, quality control, and accountability so you get specialist quality across 26 services without managing 26 contractors.

What happens if a vendor fails or underperforms?

We replace them. Continuous inspection and scoring catches issues early, and our vendor network is deep enough to reassign work without service interruption. You never deal with vendor performance issues directly.

Who is responsible if something goes wrong?

Keystone is. One contract, one manager, one accountability point. Call your Facility Solutions Manager — we resolve it with the vendor and report back.

What services does Keystone coordinate?

Twenty-six commercial services across four categories: Cleaning, Maintenance, Repair, and Facility Solutions. Janitorial through pressure washing, HVAC through snow management.

No. Locally operated, non-franchise, established in Washington in 2003. Directly accountable to local clients — not a corporate parent.

01 / The Difference

Most facility managers work with five vendors when they should be working with one.

The Old Way

Five vendors. Five invoices. Five excuses.

You spend more time chasing contractors than running your facility. Quality is inconsistent, response times slip, and accountability disappears the moment something breaks.

Separate contracts for cleaning, maintenance, and exterior care
No single owner when something falls through the cracks
Hours every week coordinating crews and chasing follow-ups
Surprise costs scattered across multiple invoices

The Keystone Way

One contract. One contact. One standard.

A dedicated Facility Solutions Manager runs every service for your building — vetted vendor network, proactive scheduling, and a single line you call when anything needs attention.

One agreement covers cleaning, maintenance, repair, and facility solutions
Your manager owns quality control and scheduled walkthroughs
Proactive scheduling so issues are solved before they're complaints
Transparent monthly reporting and a single consolidated invoice

04 / How We Work

The Keystone process: five steps, then your facility runs without you having to think about it.

Step One

Assess

A no-pressure walkthrough of your facility. We map every service touchpoint, current vendor, pain point, and gap in coverage.

Step Two

Customize

You receive a tailored service plan and a single transparent quote that consolidates the work currently spread across multiple vendors.

Step Three

Coordinate

We assign vetted vendors, schedule every service, and run quality control. Your dedicated Facility Solutions Manager owns it end-to-end.

Step Four

Communicate

Monthly walkthroughs, transparent reporting, and one phone line for everything — no escalation paths, no voicemail mazes.

Step Five

Control

We continuously inspect, score, and replace vendors to maintain Keystone standards. Performance never drifts — accountability stays with us.

05 / Service Areas

Local crews across the Puget Sound.

We coordinate vetted vendors across the Puget Sound and serve the major commercial districts of King, Snohomish, and Pierce counties — same standard, same dedicated manager, regardless of address.

06 / Why Keystone

You don't need more vendors. You need one accountable partner.

Keystone exists to eliminate vendor chaos — by owning the result, not just the service. We don't deploy our own crews. We do something more valuable: we make sure the work gets done right, every time, by specialists we vet, supervise, and replace when standards slip.

We work with a vetted network of specialized vendors, selected and managed by Keystone. You get a single accountable partner who guarantees performance — without the overhead of running 26 contracts and 26 vendor relationships yourself.

Every vendor in your service plan reports to your manager. Quality issues, scheduling conflicts, response delays — all routed through one accountable owner.
03
Schedules every service
Cleaning rotations, preventive maintenance windows, quarterly walkthroughs — coordinated so services don't conflict and nothing falls through the cracks.
04
Handles every issue end-to-end
You report it once. Your manager dispatches the right vendor, supervises the fix, verifies completion, and reports back. You never escalate, you never repeat yourself.
05
Performs ongoing inspections
Scheduled facility walkthroughs, vendor scorecards, and proactive identification of issues before they become tenant complaints or capital expenses.

07 / Client Voices

What facility managers say after they stop juggling vendors.

The single biggest operational change we've made in three years. One contact, one number, one invoice — and the floors have actually never looked better.

Property Manager

Class-A Office Tower

Their team caught a slow leak during a routine walkthrough that would have cost us a full ceiling replacement. That's the value of having a real partner.

Operations Director

Multi-Site Medical Group

I used to spend my Mondays chasing five different contractors. Now I spend them on actual work. That alone justifies the contract.
