About
Fifteen years of keeping Abuja’s buildings running
Keystone began in 2011 with six engineers and one generator contract in Garki. Today we look after 64 buildings with 1,150 people, and we still answer the phone ourselves.
What we believe
Facility management should be boring
When we do our job well, nobody notices. Lights stay on, water runs, lifts arrive, and the building feels calm. The drama only shows up in our monthly report, where every fault, delay and litre of diesel is accounted for.
That is why we measure everything, put response times in writing and accept service credits when we miss them.
