Wow! What can I say? A relative of mine recommended Mathew from Diamond window cleaning and I’m so glad I contacted them for a quote. Mathew arrived on time, provided a quote and achieved what he promised. He even followed up after some rain that day to ensure I was still satisfied with the service, that in itself was impressive!!! Thank you! I highly recommend this company for your window cleaning needs, you won’t be disappointed. 👍🏽
