"I initially selected West Shore Home to do my window replacement principally because their salesman so much less pushy than the others that I requested estimates from. I am allergic to a hard sell! But their excellent service continued throughout the project. I needed a total of more than 20 windows replaced in a 70-year old home. Quite a job! They scheduled the installation well in advance so that I could plan my schedule. They came exactly on time on the appointed day. Everyone on the crew was cheerful, courteous, and knowledgeable. When it turned out that some of the materials sent from the factory had minor defects, they not only offered to replace all the defective panes but even showed me a couple of defects that I had not noticed. And they returned not once but twice to be sure that everything was perfect before they called the job complete."

"William contacted me within 30 minutes of requesting service through Angi. He was at my house within the next hour, discovered the cause of my busted water line, and completed the job quickly. After 2 days without water and trying several plumbers for help without success, I remembered my Angi account. This was the 1st time I'd used Angi and am so glad I did. I will be calling on this company again in the future for other repairs. Highly recommended."

"Shower renovation was completed by premier-homepros.com back in May of 2025, after several weeks we noticed a water stain in the flooring adjacent to the bathroom. The company came back out and admitted that the employee who did the work has sabotaged some of his previous jobs and was terminated. They then opened the wall behind their work and discovered black mold from the leak. There was also water damage the flooring and subflooring. The homeowner to contact some companies to get estimates on getting this resolved. Homeowner is disabled and suffering from brain cancer and dementia. After consulting friends in the industry (general contractors and residential insurance) it was decided that handling of this matter should be done by the company who knowingly and admittedly sabotaged the work. This is not acceptable. Reached back out to the company several times and were delayed even further. We are now entering our 6th month of this dispute and have no bathroom to use"

Install Boiler questions, answered by experts

Scale from hard water is hard to diagnose until it starts causing problems. If your area has particularly hard water, that’s most likely what your boiler is using. If scale build-up becomes a problem, it starts to cause decreased flow and heating, and eventually, valve failures as valves become blocked. Let boiler professionals know if you’re worried about scale and they can offer advice or implement a solution.

Boilers are equipped with multiple safety features to ensure safe operation. These include pressure relief valves to prevent overpressure, temperature high-limit switches to avoid overheating, and flame failure safety devices in gas boilers to cut off the gas supply if the flame goes out unexpectedly. Low water cutoffs prevent operation with insufficient water levels, and pressure gauges help monitor pressure levels. Ventilation and flue systems prevent the buildup of harmful gasses. Boilers often feature error code systems for automatic shutdown during malfunctions and gas leak detection for safety. Regular maintenance is crucial to ensure these safety features function correctly.

Since your boiler keeps you warm and provides hot water to your home, you’re likely to notice issues with heating in your living space right away. The most obvious sign that your boiler is breaking is not getting any heat or hot water. You might also hear some odd sounds coming from your boiler during operation, the flame in your gas boiler is not blue, the pressure is inconsistent, or your boiler is using more energy than it should. If you notice any of these signs, be sure to call a pro right away.

It can take anywhere from four hours to three days to replace a boiler with a new one. How long your particular boiler installation takes will depend on whether you need a gas line installed and if you’re switching to a new boiler system. 

Replacing a combination boiler or standard boiler with the same system should only take four to six hours. Meanwhile, switching from a conventional boiler system to a combination boiler system could take a few days.

Using heating oil to heat your home has its advantages, but it also has its disadvantages. 

Consider these drawbacks before installing a heating oil system:

  • Heating oil prices fluctuate frequently

  • Risk of oil spills or leaks

  • Produces more air pollution and soot compared to a gas furnace

  • Regular maintenance required for equipment

  • Need to reorder heating oil consistently to avoid running out
