"After talking with several plumbers, I decided to use Southeast Plumbing and Gas. Brian answered all of my questions and quoted me a very competitive price. Brian installed a new dishwasher, put in a new tankless water heater (plus ran new electrical for the unit) and some other smaller fixes. He was professional, courteous, and did the work for what he quoted. He also tackled some additional plumbing issues that cropped up while he was doing everything else. He was at our house for over 12 hrs fixing everything and making sure everything was working properly before he left. I would definitely recommend SE Plumbing and Gas and would use them again."

"Went great. Maddie H. came by and found the problem with my old water heater. She setup the install for me. Bradley K. installed the new water heater the next day and did an excellent job. Both individuals were very knowledgeable and a pleasure to work with. Great job to everyone concerned. Thanks!"

"Electrician was prompt and friendly. Worked very quickly. I had purchased a full day and he had gotten through most of my items by the mid-day point. A couple of my ceiling fan light kits were not working properly and needed a little extra attention to troubleshoot. Also the doorbell I had purchased needed a transformer in order to complete install. The tech was eager to leave and said he would come back another day if wanted him to. When I tried to schedule a follow up, he was booked up for at least the next 3 weeks. I was disappointed that since I had paid and booked for a full day, he didn't stick around long enough for me to run to the store and get whatever supplies might be needed so the job could be finished that day. Also after he left, we realized one of the regular light fixtures that was installed wasn't working. Considering I paid for a full day and only got a half day of work, and had to pay someone else to come back and finish the job, I don't feel like I got a great deal."

"A large tree fell on my home during storm & I hired another contractor to complete repairs which included replacing 9-12 rafters/sheathing/shingles, re-building small front porch & adding 3 windows to sunroom. Original contractor installed the windows & did a lot of work on the roof but were very slow & work was sub-par.....they also had issues getting project permitted & I finally had to let them go. I was in a real bind to get repairs completed as I was in the middle of re-financing house when the storm hit. I contacted Commonwealth & they were able to come out & assess what needed to be done. They got the permits right away & got started. Most of the previous work had to be re-done....they removed the windows & added headers & proper support & re-installed, repaired roof & re-built front porch. All work was done professionally & in a timely manner. Also installed interior trim (baseboards/windowsills/frame) in sunroom, which I requested at the last minute, so house would be ready for appraisal. They did a nice job matching the original trim on older home. Would definitely hire again."

Install Boiler FAQs, answered by experts

The best time to buy home heating oil is in the summer when the demand is lowest, as the prices are usually lower. However, waiting until the summer to buy is often unavoidable unless you install a separate storage tank. If you have the space for a second tank, you can expect to pay between $1,000 and $4,000 for the oil tank replacement or installation, depending on the capacity and location. You could quickly recuperate these costs, though, by stocking up on heating oil in the summer and avoiding deliveries in the winter when prices are highest.

If you have a closed-system boiler that requires an expansion tank, you cannot safely operate it without one, as this risks extensive damage or even explosions. You must find a way to make room for the installation. Options include repositioning the boiler, rerouting the boiler piping to a more open area, or performing minor remodeling to create the necessary space. If you are unsure whether your boiler needs an expansion tank or how to best accommodate one, it's recommended to have a local heating service professional assess the situation. They can confirm the requirement and suggest the most practical solution.

If you hear your radiator clanking even when it’s turned off, it’s typically because there’s trapped water or air in the system, causing a pressure buildup. When you hear significant clanking, popping, crackling, or banging in a radiator that’s turned off, you’ll want to bleed the pipes or call in an HVAC specialist to deal with the problem (and prevent it from happening in the future).

Costs depend on issue severity, parts needed, and labor rates.

An expansion tank must always be installed on the supply side, which is the side where the boiler sends water out to heat the systems. That placement allows the water to push against the air and condense properly as it is heated, then circulated through the system. Professional installers can recommend the best place on the supply side for an expansion tank.
