Additional service area - Cohasset, Fitchburg, Worcester, portions of Chelsea-Saugus, Chelmsford Counties. South Shore & Cape Cod and All of Rhode Island. Family owned and operated since 1984. Additional email - [email protected]. Additional phone - (800) 439-0788. Additional DBA - Pioneer Basement Waterproofing Inc.
"I had the estimate for the work done which went fine, then called to book the appointment. Was required to put down $200 for the $650 projected repair cost. I did this thinking there would be no issues between then and the repair date. My wife is quite pregnant and we had to move up the repair date to get the nursery ready in time for their birth. (twins) When I called to cancel this appointment and seek a refund of the $200, I was told that the window to cancel was 3 days from the scheduling and that I was forfeit my deposit. This information is in the contract, but I did not catch it at the time. I could only imagine if this were a bigger project and something like this happened to someone else. For the cost of $200 Pioneer Basement has not only lost me as a future customer, but forced my hand in posting several poor reviews such as this one. For any future customers, pay very close attention to this and hope "life" doesn't happen to you in between. Good luck."

"I was very impressed from the beginning to the very end of my shower project with Patriots. They were able to take an empty space in my bathroom and create a plan for a shower that would fit in that space. I especially liked how I was able to see and feel some of the components they were going to use, let me pick the colors I needed and showed me pictures of how my new shower would look went it was done. All the workers were very respectful of my house while doing the job, very knowledgeable and explained what they were doing as they went along working. I would definitely recommend Patriots Bath Remodeling to anyone needing to either replace or start a new project in their bathroom. "

FAQs for water heater service projects in Dennis, MA
The average cost to install a new water heater is around $1,300, but you can expect to pay between $875 and $1,750, depending on the kind of water heater, the size of the unit, and the professional chosen to complete the work. Tankless water heaters can push your price higher, as installation is more complicated, with prices as high as $3,500. The location and accessibility of your water heater will play a role in the project cost, as those sitting in tight spaces like a crawl space will drive up your labor costs.
Tankless water heaters are more expensive than those with a storage tank, but they come with some impressive benefits that most homeowners find worth the higher investment. Most importantly, they provide unlimited hot water, so you’ll never run out like you would with a storage tank. Tankless heaters are also more efficient, so comparing gallon-for-gallon, you’ll spend less on hot water with a tankless heater. Tankless water heaters are also smaller, require less maintenance, and tend to last longer than storage tank water heaters.
It usually takes a professional water heater installer between two and three hours to remove an existing water heater and install a new tank heater. However, it could take four to five hours if they have to work in a small utility closet or another tight area, like a crawl space. Tankless water heaters have a more complicated installation process, so they will take a bit longer. Additionally, a gas water heater requires a connection to a gas line, and that alone can add about an hour to the installation timeline compared to installing an electric water heater.
It is very difficult and dangerous to install your own water heater, so we strongly recommend against tackling this as a DIY project. Not only will you need to wire your water heater, but you’ll also need to connect plumbing to the intake and outlet. Sweating copper pipes and connecting wiring properly are skills most DIYers don’t have, and even if you do feel confident you can do it, working with water and electricity always leaves the potential for electrocution. Hiring a local water heater installer is well worth the investment.
In most municipalities, a license is not mandatory for water heater installation or replacement. However, we strongly recommend hiring a licensed plumber or water heater installer to handle the work. Licensed installers are far less likely to make a mistake during the installation, which means paying for the experience decreases your risk of a leak and other issues. You can use our state licensing tool to find out if a contractor you’re considering in your area holds a plumber’s license.
