I know we had snafus getting you guys over here but Aaron showed up today and found out what the problem was corrected it and he also went above and below at the exact right time when I was asking him a question he came down on the ground and grabbed a bolt and helped put up the differential cover that I was working on By starting a couple of bolts! Also, I would like to thank Morgan in the call center for not only getting somebody here today but a supervisor, nice job, thanks again.
Christopher, was great he came to do what he had to do. He got a job done. And I'm very pleased with her, thank you, Chris.
I have used Gem in the past for both plumbing and electrical issues. This time it was a blocked kitchen drain. Turns out it was more than a blocked drain in the PVC under the sink. Nicholas snaked the entire line (down to the basement) to clear out grease and "gunk" that has been literally decades in the making. Because of how this job was handled and because of how the tech talked to me, I am contracting to replace the VERY old 1950's era cast iron pipes in my home.

UPDATE: Work was quickly scheduled. Nicholas arrived today and completed the work. It was a big job. Excellent work.
Chris and Anthony were polite considerate and professional in knowing their jobs and sharing important information concerning our unit.
I really appreciate the honest and integrity in handling our issues. Made us feel confident in our decision making. Very professional but yet personable.

Got a problem with your well pump not working? Not a problem! Call Gem plumbing & heating services. Our 100’ deep well finally lived out its life and stopped working. Not a pleasant experience when suddenly you have to get water somewhere and start filling up buckets. I called on Saturday and they came by within a few hours. They checked the pressure tank first then the well. They came back Monday and installed the new pump. I couldn’t have asked for better service! They were there when I needed them!

Why does my Medford home near the river stay humid?

The Mystic River valley holds moisture, especially in neighborhoods like South Medford and near Wellington. If your home feels clammy even when the AC runs, you may have undersized equipment, condensate drainage issues, or need whole-home dehumidification.

How often should Medford residents schedule AC maintenance?

Annual maintenance is recommended for all Medford homes, especially older systems working against river valley humidity.
