"Called to have a boiler that is less than 7 years old cleaned. It’s easily accessible. I have mentioned that the pipes were banging at the far end of the house when the heat came up. The technician came and went, never mentioned the need for any new parts. I was shocked to see I was billed $784.00. Three hours and fifteen minutes at $195.00 an hour and the remainder for parts. For a seasonal cleaning ? You call that efficient and professional ?"

E.F. Winslow Plumbing & Heating
E.F. Winslow Plumbing & Heating
Founded in 1971 by Freeman Winslow, E.F. Winslow began as a small plumbing company. Today, E.F. Winslow has proven itself as Cape Cod's most reliable service company for plumbing, heating, air conditioning, electrical, septic, oil delivery, central vacuum, remodeling and kitchen and bath design.
"Unresponsive and Unprofessional. Workers didn't show when they said they would. They did not finish the job, but told me they did. Left trash everywhere. They also installed an outdoors unit on my neighbor's property and want me to pay $7,500 to move it. This would have just been a simple fix, but they have been making it extremely difficult leaving me no choice but to file a complaint against their license and their bond."

"DO NOT SPEND YOUR MONEY HERE!!!*** Called this company inquiring about their services/to discuss the problem I was having with my Panel. Spoke with Allura on 10/5 who was very helpful & pleasant. Upon speaking with her she made me aware they could send someone out the following day. She told me it’d be $95 for every 30 minutes but that they typically find the problem within that first thirty minutes. if any work was done that same day the $95 would then be deducted off my bill. Awesome right? Wrong. She gave me INCORRECT INFORMATION. Fast forward to 10/6 they come out to my home. (Wish my husband had gotten the gentlemen’s name who had actually did the work but unfortunately he did not.) within the first 30 minutes they indeed did find the problem, the floats on my septic pump were stuck with grease. The worker said all that needed to be done was to power wash them to clean up the gunk and that we’d be all set. A little over an hour later the man then knocks on our door and says everything is all set. That we had one float he felt needed to be replaced but he doesn’t like replacing just one so he went ahead and replaced all 4 at the cost of $150 EACH! He did work on our property without fully disclosing what exactly he would be doing we were upset but obviously had no other option but to go along with it and pay. The work was already done. We got our bill which was $800 unsure of where he got the number from he broke it down and stated $600 for the 4 parts he replaced at the price of $150 each and $195 for a technical service fee that they charged everyone just for coming out. I explained that’s not what I got told yesterday, Allura said It would be $95 and if I got work done that $95 would be deducted. He couldn’t honor what Allura told me and suggested I call the company. So I did, I called the company. Allura was out, so I spoke with her supervisor Robin, who was oh so sure I didn’t get told that, that’s not their policy and the $195 is non refundable. She said she would call Allura and see if that’s indeed what she did say so we can resolve the issue. I got a phone call back from Robin an hour stating that Allura did indeed make a mistake and tell me that information but the $195 is non refundable and there wasn’t much she could do. I didn’t get an apology or any sincere sense of remorse for the inconvenience they set upon their paying customer. I was disappointed and that was clear, she then spoke with the owner who said all he could do was give me $95 off my next service with them.. lol sir you technically owe me much more than $95 and I will never be doing business with your company again. So thanks but no thanks. PLEASE TAKE YOUR MONEY ELSEWHERE!! THIS COMPANIES CUSTOMER SERVICE SUCKS! They absolutely do not honor their word, and obviously DO NOT TAKE RESPONSIBILITY FOR THEIR MISTAKES. HORRIBLE."

Aqua Services Plumbing & Heating
Aqua Services Plumbing & Heating
Plumbing, Tank-less/ On-demand Water Heaters, Heating, High Efficiency Boilers, Ductless Air Conditioners,
"We noticed a slight leak around the base of the main-bath toilet, so we called a few plumbers. Aqua was the only one that had a live person answer the phone. Megan from Aqua took down the information on our plumbing issue and indicated a plumber could come out first thing the next morning. Tyler, the plumber from Aqua, called us first thing that morning to say he was on his way. He arrived shortly after with his assistant, and he replaced the toilet wax wing with two rings. We also asked him to check the slow-draining sink in the main bath, which he snaked. He then made sure both the toilet and sink drain were working well. Megan from the office left a voicemail the other morning to check on things. The job went well from Megan's scheduling and "after-care" call to Tyler's work."

"Our heater stopped functioning on Nov 27, 2023 and we called Petro who had done the maintenance on it before and replaced a motor two years ago. They were responsive and a technician came two days later. He worked for 3 hours without explaining what the problem was. Then said he needed to replace the motor. He fixed the problem and left without much explanation. Two days later a bill of $2500 came via email. No explanation, no break-down. I called 4 times over the last 20 days, spoke to 4 different reps and was promised that a supervisor will contact me with the bill details. Nothing happened. Irresponsible customer service and unprofessional behavior. They show all the symptoms of big, bureaucratic, and indifferent service company. I would not recommend Petro if you have options of more personalized services."

The East Dennis, MA homeowners’ guide to water softener services
From average costs to expert advice, get all the answers you need to get your job done.

How much a water softener costs depends on your home’s size, and the system’s type and capacity. Our expert guide explores all the price factors.

On average, a reverse osmosis water filter costs around $2,200, but there are a few variables that impact the total price. Learn about them in this guide.

Your cost to install an under-sink water filter will depend on the type and size of system you choose and whether you need professional installation.

Why does my tap water taste salty? Common reasons why softened water tastes salty range from a broken water main in your city's water supply to debris buildup in your brine tank.

Considering reverse osmosis versus carbon water filtration for your home? Carbon filters can remove some impurities, but RO removes a lot more.

Not all states allow you to dump water softener backwash outside. Keep reading to learn where to discharge water softener backwash for your home.
