Fantastic company! Seamus did a great job with our shower and toilet. He is very knowledgeable and could answer all our questions. We’ll definitely stick with O’Neill Bros if anything comes up in the future.
We got an exorbitant quote from a large company in the DMV area (FH Furr) for a handful of plumbing items and decided to call O'Neill Bros for a comparison. They were far more affordable, faster, actually on time and professional in completing their work. Would highly recommend for anyone in the DMV area looking for plumbing services
We have used O'Neill Bros. Plumbing twice and they will be the company we call IF we need plumbing work. They are extremely prompt and professional and very experienced. They were able to due a same-day estimate and next-day installation on a new hot water heater this week and we are very happy with their work and their pricing was more than fair for top quality work.
Life savers. Our boiler went out resulting in no heat in our home. This lasted several days as two HVAC companies came and failed to repair the boiler. One of the HVACs guys told us it was a job for O'Neill Bros.--who are very well regarded among their peers. Patrick was able to come by the house the same day that we called (despite it being a busy holiday season) and had us up and running in just a few hours. Not only was the service timely and professional, but it also saved us from the expensive headache of a boiler replacement that the other vendors were trying to push on us. We are grateful!
These guys are terrific! Had a water pipe leak in my kitchen ceiling on Sat which then burst onto the floor. I called them in the morning and they came by noon. Chris and Seamus were the absolute best! Capped the pipes so no more leak and explained the alternatives for a needed re-piping. I highly recommend them.
