ThanksPosted on Indrawati SunarjaTrustindex verifies that the original source of the review is Google. Had issue with having cold shower, was thinking of replacing the water tank (5 years old). Called Expand Plumbing (based on good reviews they have) and they sent Ben to our place within hours. He then simply clean the valve and we got hot water again with very reasonable fee (no call out fee). Ben was fantastic and explained to us the problems clearly.

My gas System needed certification, and James was all over it. He double checked everything and made sure it was up to spec Service was excellent, on time and quick. Would absolutely recommend Plumbdog and their servicesPosted on nicole schnitzlerTrustindex verifies that the original source of the review is Google. Thank you Alec and Sarah! I know diddly squat about water pipes, so when our front water meter was going off like a frog in a sock, and it was almost 5pm - needless to say, I got a bit panicked. Sarah sent me the easy-to-navigate booking form, and instantly, Alec was on his way. Alec figured it was a water corp issue and he very accommodatingly called them for me and explained the issue. The nicest, fastest and professional service I have had in a long time. Expand to the rescue!Posted on Shayne SmithTrustindex verifies that the original source of the review is Google. I recently had a fantastic experience with Expand Group Plumbing! They sent out a couple of young guys who were not only well-mannered but also efficient and professional. They got the job done quickly and made sure to clean up thoroughly before leaving. I couldn't be happier with the service I received. Highly recommend Expand Group Plumbing for anyone in need of reliable and quality plumbing services!Posted on Claud LinTrustindex verifies that the original source of the review is Google. Ben and Ryan helped fix a leak in my kitchen caused by cracks in the drain. We also discovered that the drain was blocked, and they assisted with clearing the blockage. Their service was very professional. Thank you very much!
