Customer Say
What Our Clients Say About Us
Homeowner
Castro’s handled my boiler installation quickly and professionally. The team was polite, clean, and explained everything clearly. My heating system works perfectly now, and I’ve already recommended them to friends. Honest, reliable, and highly skilled service.
Landlord
I booked Castro’s for a Gas Safety Certificate and routine service. The engineer was on time, thorough, and explained everything. They issued my CP12 certificate same day. Stress-free, professional service I can trust every year.
Property Developer
Castro’s took care of first and second fix plumbing on my renovation project. The work was precise, on schedule, and finished beautifully. Their team coordinated seamlessly with other trades. I’m impressed and will hire them again.
