"Charged $2,000 (that's right, $2,000!) to install a new sprayer faucet and soap dispenser in Boston. $1,500 went to labor, which took less than 2 hours. I'm sorry, but $750/hr is outrageous. I did pay it because I wanted to expedite solving the problem for the tenants, but I now regret as their dishwasher is not working and I suspect the plumber failed to reconnect everything probably."

We offer turnkey solutions for both residential and commercial customers — no job is too large or complex for our expert team.

"Absolute ripoff, along with shady business practices. They were prompt and courteous, but that's about it. The technician came and had to replace a $200 part on my boiler, it took him under an hour to do the work. A simple Google search showed at least 10 places to buy the exact part, all around $200. No other parts were needed for this repair, I researched what is involved. I was charged almost $1000, including their $89 diagnostic fee just to walk in the door. So apparently it's a $600+/hour labor rate? I'm obviously in the wrong line of work. This was not an off hours emergency call either, it was a scheduled appointment in the middle of a weekday. The shadiest part of the entire thing was that on the invoice (that they email you later) they bury all the cost, it's not itemized i.e. labor vs parts cost. It just says replaced (part) = $1000. A super scummy and shady way to run a "professional" business, taking advantage of people who don't know any better. I wouldn't be surprised if they also sell used cars. Never again Gervais. You've all been warned."

Growing up, my Dad had a someone for just about every issue that life could throw at him. Car’s making a funny sound? “Call Mr. Genese.” No hot water? “Call Mr. Martin.” Need a sport coat for my first job interview, “Call Mr. Antista.” Those people cared about my Dad and his family, they did great work, and most important, their advice could be trusted. Yellow Dog is bringing back old school customer service, with plumbers and HVAC technicians who are highly technically competent, and more important, who really care about your family and can be trusted to give you the best advice. We believe that old school customer service, paired with the latest technology to make setting up your appointment and communicating with us easy, and of course the highest quality work is what our customers deserve. Thank you for taking the time to learn a little more about us, and we hope you’ll give us a chance to earn your trust. We’re Yellow Dog – and we’re always by your side. Pat Dunn, CEO

"Hello, Yellow Dog Home Services was phenomenal! Jeffrey was able to come the same day, complete an assessment, and define the next steps for the installation of a new hot water heater the following day. He is very personable, professional, knowledgeable and affordable. Yellow Dog is now saved in my iPhone for future project needs! Richard"

Plumbing questions, answered by experts

Vinegar is better for an AC drain line because it’s less corrosive and won’t damage the pipes. It’s also a safer and easier product to use. Bleach should not be used on your AC drain line because it can corrode your pipes and harm the evaporator coil in your air conditioner.

To create a siphon break and remove any chance of dirty sink water or water that backs up into the sink from getting into your dishwasher, your dishwasher drain hose needs to have a high loop or an air gap device as part of its installation. All building codes require at least a high loop. In many places, it’s necessary to install an air gap device to meet the code.

Plumber schedules can vary. Many plumbing companies follow a traditional five-day work week, and schedule plumbers so that someone is available during working hours. However, some plumbers choose a four-day work week and take a day off, usually Friday. In these cases, Friday work counts as weekend work and will incur the same extra charges.

No, they are two different things. Some tanks have a pressure relief valve built in. The purpose of this valve is to prevent the rupturing of the water heater due to pressure generated during the heating process. An expansion tank redirects water from the heater tank to relieve pressure so while they have the same purpose—alleviating pressure—the expansion tank is the only item actually redirecting water. 

Having the right size pipe ensures proper drainage and helps protect against clogs and other plumbing problems. A pipe that's too small will take longer to drain, which can result in backups. And solids can build up in pipes that are too large. Choosing a pipe with the appropriate volume also means it will be able to handle water pressure, which is the force behind the water.
