What we do

One contractor instead of six

Managers are buying a single number and a paper trail. That's what this is built to be.

Planned Maintenance

Scheduled programmes with annual budgets and asset registers.

Compliance

Gas, electrical, fire and legionella testing with certificates filed to you.

Void Works

Turnarounds between tenancies, photographed and signed off remotely.

Communal Areas

Cleaning, grounds, lighting and door entry across blocks and estates.

Out of Hours

A genuine 24-hour line for the 4:40pm Friday call.

Our story

We publish our SLA compliance because most contractors won't

Adaeze came from the agency side and knows exactly what a manager is being measured on. Keystone reports SLA compliance to every client every month — currently 97.4% — and every job carries time-stamped before-and-after photos, so the manager can answer a landlord without phoning anybody.

Monthly SLA compliance reported to every client
