Nancy Pascua ★★★★★

Just fantastic service. Spent extra time trying to figure out a mysterious water leak. Super professional and knowledgeable. Gave me options and time to decide how to proceed. Would use again and would recommend to anyone.

Bev Battaglia ★★★★★

Fantastic job by Galaxy Plumbing! Appreciated the professionalism and informative service from this team. I had a toilet and sink back up issue which the technician was able to come and resolve the same day I called. At the same time, recommendations were shared to prevent similar issues in the future. Great attitude and top notch workmanship!

Jason Lobo ★★★★★

Rob's service from start to finish was exceptional. Spoke with him about getting a dripping bathtub faucet fixed. Walked me through how to remove the valve cover. Also correctly guesses that it was a water cartridge issue. Booked a plumber the next day and sent me a text with the ETA. The communication through out was fantastic. For some one who has never booked a plumber for a smaller job, understand that it's not cheap. And you have to consider the cost of parts if not covered under warranty. Would definitely recommend Rob and use his company again if needed.
