We had the pleasure of working with Graeme for a GSC check at one of our properties and we have to say, he's the best.He arrived on schedule, was highly reliable, and communicated clearly throughout. The inspection was thorough and completed to an excellent standard, demonstrating real attention to detail. His pricing was fair and transparent, offering great value. Graeme was friendly, professional, and respectful, and left the work area spotless. I would highly recommend him to anyone.
