The cost was very reasonable
Three things fixed. The water pressure and hot water flow was not working in our master bathroom - fixed. A repair to our deck caused a pipe to be broken - fixed. And lastly, an outside water supply was added on the new deck.
The technician arrived on time, knew what he was doing, flexible to look at other repairs/additions needed and the same technician that repaired a gas leak and ventilation problem with our dryer.
The cost was very reasonable and the billing process was prompt and courteous. Setting up the appointment was easy too, just give them a call.

I am very happy with my experience with Coastal Mechanical.

Kathy Crowley
Nothing but praise for Coastal Mechanical
For both electric and HVAC, I have nothing but praise for Coastal Mechanical. They outfitted our new home for heat, A/C, and electric. They recommended the ideal zoning for our thermostats. They provided detailed diagrams and walk-throughs so that we could specify exactly where we wanted switches, outlets, and fixtures placed. And when we decided we needed additional lighting in the laundry room, they seamlessly added it in short order. When finished, it was as if it was there from the start. I unconditionally recommend their services.
Ed Trembicki-Guy
Excellent Work
We have had several projects done with Coastal Mechanical. The latest was to update the lighting in a remodeled area of the kitchen area. The advice was excellent and attention to detail was appreciated. A fair price and I recommend them for your projects. Excellent work...thank you!!

Coastal Mechanical Is an Outstanding Contractor
Coastal Mechanical is an outstanding contractor. They were responsible for both electrical and plumbing during an extensive renovation of our home in Sandwich. They are clearly committed to ensuring that work is done properly and to a very high standard.

We have used them for additional work beyond the renovation, and they continue to be a company we trust and rely upon to work in our home.
