"This was one of the worst remodeling experiences I?ve ever had. I was completely oversold on what they could deliver. I hired them for a bathroom remodel and was promised a spa-like retreat. What I got instead looked like a cheap hotel bathroom. The price was outrageous. They pitched me at around $38,000, and I agreed because I thought I was getting a high-end, premium product. That was absolutely not the case. The materials and design options were extremely limited. They only work with one brand, and they push it aggressively like a bad timeshare presentation. To make matters worse, the price didn?t even include the vanity or any accessories. I had to provide all of that myself. For nearly forty grand, that is completely unacceptable. The workmanship was okay, not great. They were in and out in a day, which was convenient, but it clearly came at the cost of quality. There are spots where the work looks rushed and careless. This is a $15,000 bathroom at most."

Install Boiler questions, answered by experts

Always consult your manual for specific pressure numbers. Many expansion tanks come pre-pressurized at a specific PSI range, anywhere from 12 to 40 PSI, designed for a range of home boilers. You should not have to pressurize an expansion tank yourself, only the boiler system. If your system has a tank that needs to be manually pressurized, this is generally a job for professionals and their tools.

No. Boilers and water heaters are not interchangeable because they serve different purposes. A water heater will never be able to supply warm water or steam for your central heating system. In most homes, a boiler and a water heater may be combined to provide heating and daily use of hot water. Other homes may opt for a furnace over a boiler for their heating needs.

Radiators are a popular home heating choice in older homes, but they are becoming less common in new-construction homes. According to a 2022 report by Elements Visual Capitalist, only around 1.3% of new single-family homes have radiators and similar heating systems, such as baseboard heating.

While they may not be as popular as they once were, radiators today come with more energy-efficient features that can make them practical for modern homeowners.

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

Safety concerns with propane boilers include proper venting to prevent carbon monoxide buildup, secure gas line connections, and regular inspection of safety controls. Professional boiler installation and annual maintenance are essential to minimize risks. Having a carbon monoxide detector installed in your home is essential for early detection of any leaks or ventilation issues.
