"We hired Plumbing Tree to fix an improperly installed flange by the builders of the home. The quote from them was a little high, but calling around it was similar to other plumbers. The plumber agreed that the flange was not installed correctly (rotated 90 degrees) and the bolts were stripped. The first appointment was missed, I got a text message an hour before he was supposed to show up saying that he could no longer make it due to the current job going long. The next day, I got a text right before our installation time window that he would be late. The plumbers were professional and seemed to be doing a good job. They were thorough and cleaned up after themselves well. The sink wasn't caulked as we want to touch up the paint first and he was very kind to actually leave us a tube of caulk and a rag for the job. After the job is done, there are two things that are bothering me. The first was that the flange (double flange to increase the height) was installed in the same 90 degree rotation as the initial one, so honestly I am a bit confused on this (the slots where you are supposed to put the bolts in every single manual on toilets are at the front and back instead of the side and the top and bottom slots were used on the sides instead). The toilet itself is slanted, not perpendicular from the wall (not by a huge amount, but it is noticeable). Since it is caulked down on our new floors, it is going to be permanently off square. Over all, I think they had a good attitude and the job that was quoted for 1 1/2 hours took 2 hours, so not bad there. We are saying we would not hire again due to the rotation of the flange, the inconvenience of rescheduling twice and that the toilet was installed a bit crooked."

"☆☆☆☆☆ dream team COMPANY! I had most contact with Julian throughout the job, but his partner and Electrician were JUST AS NICE. They had cloths on my floors, as they were in and out of my crawl space. They even left to get a particular component, specific for my install. No damage to home. There was no laughing or joking around. They were concentrated on install, measuring, calculating out loud between the three of them. No cussing or profanity, either. Julian was professional and explained everything to me, including why manual was left on unit, so when inspector came, it was there, as it couldn't be signed off without it. Thermostat looks great! He also knew a lot about furnaces, which is my next thing. *Beware of companies won't give you prices on ANYTHING and/or charge you estimate to come to your house... Another reason I picked PEAK HOME was their receptionists! Sweetest, most understanding ladies! If you need to install A/C, go with this company - definitely recommend!"

"Nick our installer arrived on time and was very friendly and courteous. He worked fast and carted off the dead water heater and installed the new one. He showed us how to start the pilot light in case we needed to do it in the future. He made sure to take all the trash with him. I had called the day before to get an estimate and they were able to schedule us in right away. This company had the better price and warranty from the others I asked for prices. Abbey from the office was also very friendly and quick to send me a written estimate. There were no hidden fees and I paid exactly what they said it would be. Nick's friendliness and professionalism was icing on the cake."

Install Boiler FAQs, answered by experts

Probably not. Moving a boiler to a new location is a very different prospect from replacing it in the same spot, and significantly more expensive. Plus, boilers are typically carefully positioned in proximity to pipes and radiators when installed. Homeowners may want to move boilers to free up space, prevent freezing problems that have happened in winter, or solve a noise issue—but it’s a much more costly proposition.

The most important sign of a boiler problem is something happening unexpectedly, which is why regular boiler maintenance is important. Unexpected problems can include strange smells, new leaks, and unexpected noises that your boiler wasn’t making before. Additionally, if a boiler keeps shutting off or can’t maintain a specific temperature range, it’s time to call in an expert.

The average lifespan of a boiler is typically between 15 and 20 years, though some may last for as little as 10 years while others can reach 30. A boiler's longevity is influenced by several factors, including the quality of the unit, proper installation, and consistent professional maintenance.

The material also plays a significant role. Older boilers made from durable cast iron can last for over 20 years, with some functioning for up to 50 years. However, it's important to consider their lower efficiency, which can lead to higher utility bills. Modern boilers, often made from steel alloys, are designed to withstand high pressure and temperatures and have an average lifespan of about 20 years.

To maximize your boiler's lifespan, ensure it is installed correctly, have it professionally maintained each year, and address any necessary repairs immediately.

Most home boilers will need an expansion tank. That’s because these boilers are closed-loop systems, where the water is trapped. An expansion tank is needed when the boiler heats the water and it expands, allowing air to condense in the tank to make room for the water. Other types of boilers don’t use an expansion tank, such as traditional steam boilers, but these aren’t as common. And hot water tanks may be able to use a pressure release valve instead. When in doubt, call in a pro to take a look.

Unless they are connected to the same system, boilers and water heaters will both need their own expansion tanks. The only case they wouldn’t have separate expansion tanks is if the boiler is pulling double duty and managing a heating system while also supplying hot water for a home. In which case, you may not need a hot water heater.
