I called M.J. Flaherty on Saturday explaining that my furnace was working intermittently, and that it currently wasn't working, and the temperature was 57 in my house. They said they would send someone out on Tuesday and would call me Monday evening to let me know when they would be coming. I called them Tuesday morning to find out when they would arrive, only to be told that "he's not in the office, I don't know what his schedule is today." Crickets all day. Called again Wednesday morning, this time, "He's at a school that doesn't have heat, I'm not sure if he'll be able to make it." Again, no word. Called again on Thursday morning, "he's not in the office, I'll have to call him, and I'll call you back." Never heard back from anyone. It's Friday, and I still haven't heard back from anyone. Not a good way to run your business. If you're swamped, say so. Don't leave someone with no heat for almost a week! There's apparently a reason that they're not rated with the BBB or Angi's.

Came same day, though didn't guarantee.  Very professional and gave an honest assessment of situation.  Performed work in timely manner and line is now flowing smoothly without any leaks.

I have tried several plumbers in the past and have come back to Flaherty.  They are not cheap, but they are fair and honest.  You get what you pay for.

Tim provided expert professional advice and workmanship. In addition to his superior work, we followed his advice to deter water from going into the basement. After all the work was done, no more water! We even carpeted the basement. I highly recommend this company.

I called Flaherty for someone to put a video camera down the drainage pipes where my downspouts empty.  They only have one person who does the video work, so I had to wait a couple of weeks until he was available.  Since it wasn't an emergency, I didn't mind waiting.  Tim came out and put the video camera down both drainage pipes.  One was blocked completely with mud and sloped toward the foundation instead of away from it.  The other pipe had a separation where it should have connected to the main drainage pipe.  Tim gave me my options and we decided to replace the section of pipe that was completely blocked.  The other problem was remedied by bypassing the separated pipe with a length of corrugated pipe and a length of plastic pipe.  The digging began on a Wednesday, and the plumber dug down about 2 feet in both areas.  He dug most of the day and made the connection on the front drainage pipe.  He came back on Friday and did the connection on the back drainage pipe.  Then he filled in both areas with the soil that had been removed.  He solved both drainage issues and did not have to remove my mature Azalea shrub or my Spirea shrub.  Overall, I was very pleased with the work done by Flaherty Plumbing.

The service was great and everything went as planned.  The only issue I had was that I did not get an estimate up front, and did not know what the cost would be until all was finished.  In the end the price was fair for the work performed.

Arrived as scheduled, carefully performed work.
We have used Flaherty multiple times in the past several years for minor and major repairs and have never been disappointed.

Found the leak to be coming from cold water line in second floor bath from pipes  buried in concrete.  Had to
open ceiling in kitchen and then install new pipes to second floor bath by rerouting them. Installed new hot and cold
water pipes from basement to second floor bath for sink, commode and tub/shower installing new valves at each
location.   Panels were then put over the kitchen ceiling and wall to cover the repairs.  Work was done in timely manner
and work location was cleaned up when they finished working for the day.  Left the premises just as they found them
when the started the work.

The work went fine. 
The tech was in and out in 2 hours. 
$287 is a much higher price than is justified in 2 hours. 
Additionally, the tech handed me an "emergency work authorization form" which I was required to sign, even though the work performed was not an emergency.  This is poor professionalism on the part of Flaherty plumbing and, combined with the pricing ($150/hour), will cause me to find another plumber the next time. 
This work was not an emergency. As noted, it was scheduled.

We had an emergency on a Friday afternoon. The existing expansion tank on our water heater separated at a solder joint which sprayed water all over our laundry room. Our water heater was replaced about 5 years ago by a different plumbing company. When we called that plumbing company, they were not flexible with scheduling a repairman and suggested we call someone else.. wow!

We called MJ Flaherty for an appointment and received a courteous and professional response. Gary came promptly at 9AM Saturday morning. He explained what he was going to do before he started the job. He explained that the existing expansion tank was over-sized and not properly installed. He recommended a properly sized expansion tank for a 50 gallon capacity water heater. He replaced the copper lines where the expansion tank was installed - very well done.

Within an hour, Gary had everything completed. He left the area clean.

They did exactly what we needed and did it quickly.  We have used them in the last few years for several problems and they are always prompt, fair and professional

Replaced section of pipe to keep costs down but said it would continue to deteriorate (iron) but will do when ready.  Like a good dentist.
