A recent customer facing an insurance-inspection deadline said Josh arrived when he said he would, gave an estimate an hour later and scheduled the work for 8am the next morning. That customer said the two-man crew did the gas boiler work and a toilet flange swap from a 1970 cast iron stack, and the job was completed by noon. A recent customer said Gavin installed and rerouted piping, including adding a check valve and mechanical vent. A recent customer said Josh did a boiler install and, at the end, explained how it worked and how preventative maintenance would keep it running efficiently. A recent customer said Jermaine took care of their boiler service and hot water issue. A recent customer said Josh came to inspect a dishwasher problem and, over an hour later, charged nothing. A recent customer from Hollis said they asked to take off their shoes on arrival and left everything as clean as when they came. A 2025 customer said Josh came out to a Hampstead apartment with no heat or hot water, worked for hours on the system and came back the next day to check. A 2025 customer said they came the same day, replaced the water heater and fixed multiple other plumbing issues. A 2025 customer said Josh and his staff came for an emergency water heater replacement on a Friday night and cleaned up after themselves. A 2025 customer said he came out right away and tracked down every issue in a system a previous plumber had installed but couldn't fix. A 2025 customer with a home most of a century old said Josh had been their only choice for a plumber, on jobs from a pipe needing diverting to a replacement sump pump, drain vents and furnace service.
Great company. Very reasonable prices and thorough work and inspections. Jermaine came by and was professional, knowledgeable, and very kind. He took great care of my boiler service and hot water issue! 10/10
These guys are GREAT!! I needed several things done. They were honest about giving me the best options. They were knowledgeable, professional and down-to-earth people to work with. They showed up on time and completed everything in a very reasonable time. And when they showed up, they asked to take off their shoes and when they left, you'd never know they were here! Everything was left as clean as when they came... We highly recommend them. You won't go wrong... Rick and Shelly from Hollis, NH
I had a deadline for an insurance inspection with a couple of plumbing related issues to be completed. I called J.Davey Mechanical Contracting and received a request for an estimate WITHIN TWO HOURS. Josh arrived when he said he would, provided an estimate an hour later, and scheduled the work for the next morning at 8am. The two man crew arrived to perform the prescribed work on my gas boiler and toilet flange swap from 1970 cast iron stack. They were competent and efficient, and the job was completed by noon. Literally LESS than 24 hours from first call to complete. While I rarely have a visit from tradespeople where I say "that was cheap" ... price was fair IMO, especially given their near instantaneous mobilization. I have a tagline for them..."small enough to care, large enough to get the job done."
Incredibly fast and efficient boiler service! Definitely my new plumbing provider!
Had Josh come over himself to personally inspect what we are dealing with concerning our dishwasher. Over an hour later, with some resolve, he knew an actual service is what would be needed to REALLY GET OUT all the gunk. NO CHARGE is what Josh said knowing what we would be dealing with. I MEAN COME ON… UNHEARD OF CUSTOMER SERVICE!!! DON’T LOOK ANYWHERE ELSE. They do what needs to be done (without eating up the clock incurring more fees) plus whatever extras (within reason) are necessary without charging you for all the extras and they are always professional, courteous, and polite. This review includes two jobs combined because of the difficulty trying to leave a review for another job.
