Frequently Asked Questions

Hear From Our Satisfied Customers

My underground service failed and the utility had turned my service off. I called Landry and they came out within a few hours to assess. Explained the situation to me and what was needed for me to switch from underground to overhead in a way I could understand. Next day they were back with a crew of 3 and worked all day trying to at least get a generator going for me. In the end I had to buy a new generator and they helped me pick out and locate a generator. Next day they came back and installed and instructed me on how to safely use it. Then they came back again when the utility needed the mast head raise. Sam and crew are the best! They helped me time and again in a very stressful situation in the which I had no real idea how to navigate. They truly cared about me and my 91 year old father and did everything they could to ensure we had electricity. Will use again and tell everyone I know how great my experience has been

I found a large wet spot on my wall and thought it was either do to snow melt or a pipe breaking. Landry came out, opened the wall, and found the pinhole leak in a pipe. They fixed it easily. I will go with them again for any other plumbing issue.

The repair team were amazing. They were quick to reply back to us, very thorough, explained exactly what went wrong and how it can be fixed. Even after finding an additional issue that required another member of their to team come, they provided the proper information between each other to make sure they could get replacement parts needed, so no time was wasted. Would highly recommend.

Matt and assistant were very friendly and easy going and let me know right away what the price was and got started on the job right away. They quickly fixed my sump pump leak which was what I wanted and afterwards showed me what was done and assured me that the sump pump was turned back on after they had to temporarily shut it down and let me know it already had 3 sump pump cycles and Matt told me about some other recent sump pump stories which I found interesting - all in all I wouldn't call any other company to fix my plumbing as Landry is my plumber in Worcester as they came last Fall right after I first moved into my new house and rescued and saved me when I went to do my first load of laundry and I turned on the clothes washer and water was spraying out all over the basement floor as the connection was just hand-tightened and I was so tired of everything being so new and I was so clueless and the Landry guy was so understanding and comforting that I immediately added their phone number into my smart cell phone and said well that's my forever plumber in Worcester ! And they still are ! I wouldn't trust anyone else only Landry is who I would call - they are the BEST !

Corey Menard is a STELLAR human being as well as an EXPERT HVAC technician! He cheerfully and swiftly diagnosed an in-wall heating pipe burst, repaired it, and added a much-needed shut-off valve for one of my (three) heating zones. My English language dictionary does NOT contain the words I need to express my gratitude toward him, or express my gratitude to Landry for sending Corey to my home on Wednesday 02/11/2026. Thank Corey, thank you, and thank Corey!

We had a great experience with Landry Mechanical. Unfortunately we had on going issues with our 1.5 year old furnace that was installed by another company. Once we hired Landry they took the problems we were having on as their own. Colin and Joe were absolute gentleman. They took their time to explain stuff to me and did great work. The pricing was reasonable considering it was the middle of February and they worked with me where they could. I’d highly recommend them.
