"Technician arrived over 1 hour after the time given by office. Did not know the job specs that were given when appointment was set up. Had to return to shop as tech did not come prepared. When settling bill tech said $350. We explained that we should not have to pay road time for shop run. He called office and came back and said the cost was $350, taking the shop run off the cost. We stated that was the same cost. Tech said it was $75 for the shop run making the bill $425, so minus the $75 the bill was now $350. The cleaning of one pipe with no blockage should not be $425. Tech wore mask 2 out of the 3 times we conversed but the mask was not CDC approved, which means the customer isn’t protected. I think EcoClean needs to improve its communication with clients and needs to improve field tech and office communications."

"We had a great experience working with Wes from Boynton Builders LLC! We had a pretty extensive basement remodel / conversion to living space project that we needed help on, and we are extremely happy all aspects of this project using Boynton Builders LLC. Wes responded quickly to a voice message I left, was able to quickly schedule a time to visit to discuss our intended Scope of Work (which also involved another project re-enforcing a carrying beam and support post in our detached garage) after which he quickly provided detailed quote that fortunately fell with our budget. We agreed to move forward, and Wes went to the Town Office for us and took care of the Building Permit and were able to start our project within a couple of weeks and the work proceeded at a good clip with every stage discussed being performed in the order identified from the onset. As the project progressed, we added an additional phase to the scope of work (Install Flooring and a new double door) and he quickly estimated the additional cost got the next phase into his schedule about a week after the completion of the first / original project. Throughout the whole project Wes was pleasant, professional, motivated and productive and open to any requests for change as the space began to be completed and new ideas came into play as we were better able to visualize the final result. Wes completed all of the work on time and within the budget/ and additional scope estimates. We already have the next project planned and will be using Boynton Builders LLC again. Any friends that have seen the completed project state that it is "an incredible transformation" and we are proud to welcome friends into a space that was once an embarrassment. I would also like to mention that I originally reached out and left the same voicemail (one right after the other) for three different contractors and Wes was the only callback received, and that was within a couple hours."

"Total Ripoff! My boiler stopped working the other day and my usual company was unable to come out due to being short-staffed that day. I resorted to google and unfortunately came across Aire Serv. Their technician (who was very nice) came out to assess the situation and determined it was caused by a damaged pilot assembly. After calling around for replacement parts, I was told that the parts were out of stock until later in the week. Despite this, I was still charged $234 for the trip fee and diagnostic fee. I was then quoted $1112 for the repairs to be done once the parts were in. I shared this quote with my normal company and they were appalled! Thankfully they fixed the issue for less than half the price Aire Serv was going to charge me! PLEASE do not use this money-grubbing company, and instead use a local independent company if you need heating work done!"

FAQs for water heater installation and replacement projects in Denmark, ME

You'll need an expansion tank if your home has a closed water system, which is standard in newer homes or those with backflow preventers or pressure regulators. Expanding hot water has nowhere to go in closed systems, creating potentially damaging pressure. The expansion tank provides space for this expanded water, protecting your plumbing system and water heater from premature failure. Many local building codes now require expansion tanks, and some water heater warranties may be voided without one.

For a standard 50-gallon water heater, a two-gallon expansion tank is sufficient. This sizing assumes normal household water pressure between 40 and 60 psi. If your home has higher water pressure (60 to 80 psi), consider upgrading to a slightly larger tank for added protection. The expansion tank's purpose is to accommodate the increased volume that occurs when cold water heats up, which is proportional to your water heater's capacity.

Watch for signs like dripping water around the tank, fluctuating water pressure throughout your home, or unusual noises in your plumbing system. A properly functioning expansion tank should feel light when tapped on the bottom—if it feels heavy or waterlogged, the internal bladder has likely failed. Other indicators include frequent triggering of your temperature and pressure relief valve, visible corrosion on the tank, or unexplained increases in your water bill, suggesting hidden leaks.

Most expansion tanks have a service life of five to 10 years, though some may last up to 12 years or more with proper maintenance. Factors affecting lifespan include water quality, system pressure, installation quality, and tank construction. Hard water areas often see shorter lifespans due to mineral buildup. Regular maintenance checks can help identify potential issues before complete failure. When your water heater is due for replacement, it's wise to replace the expansion tank simultaneously, even if it hasn't failed yet.

A 30-gallon water heater needs an expansion tank if your home has a closed plumbing system. The need for an expansion tank is determined by your plumbing system type rather than water heater size. Even smaller water heaters create thermal expansion when heating water. If your home has a backflow preventer, pressure regulator, or check valve on the main water line, you have a closed system that requires an expansion tank. Check your local plumbing codes, as many jurisdictions now mandate expansion tanks regardless of water heater size.
