Our boiler broke down unexpectedly
Our boiler broke down unexpectedly, leaving us without hot water and little ones to bathe. Keystone responded quickly, diagnosed the issue right away, and had everything repaired the same day. Excellent service, and truly appreciated during a stressful moment. Thank you, Danial & Keystone!

Extremely reliable!
We had a burst pipe late at night and they arrived within the hour with the correct parts. Called Keystone who answered first time. Fast, professional, and got everything sorted quickly. Lifesavers!

New Heating System
From start to finish, the heating system upgrade was made pretty simplistic for this team. They designed a system that suited our home perfectly and installed it with minimal disruption, nothing was too much to ask and they finished on time. Daniel managed the project superbly. Will be using again
