Great experience. Very quick to reply and we’re able to come over the same day, on a Sunday. Had to replace the faucet, and they did right there. All communication remotely since we live in a different state went very smoothly.
Dave was great, very clear and honest about my options and pricing. He also wore shoe covers which is always appreciated. Communication about scheduling was quick and easy over text.
Fantastic service for a tankless water heater repair. Called them, someone came within 30 minutes, and 30 minutes later I had hot water again.
A great local company with terrific service. Dave came out to replace our kitchen faucet when we were in a pinch and did a great job. He was courteous and helpful and did the replacement up right. I’d happily recommend Green Tech to friends with similar problems!
We had a leak under our kitchen sink that turned out to be several leaks. Dave came out quickly on a Saturday and fixed it in under 30 minutes without having to replace any parts. He was professional and efficient. Would recommend to anyone local who’s in a pinch! Thanks for the help Dave!!
Came home after a 12hr overnight shift to water gushing out of the top of one of the water heaters. I sent a text to Green Tech and they responded with in 30 minutes. less than 2 hours later they were at the front door to check it out, 2 hours later had a new water heater installed. The Tech was polite and professional. Explained what he would do and the cost. If you live in Boston you know the cost for plumbing/heating/electric is a premium. But you get quality work for that price.
