"Fantastic company, highly recommended! I had a garage in an 80+ year old home turned into a finished game room / home gym, including sliding glass door and closet for storage. Highly competent from the framing down to the last details of trim work, it was all very well executed. There were a number of utilities in the space requiring access post remodel. The design was well thought out and aesthetically pleasing to the point they look like design features! The rest blends seamlessly into the space. The sliding glass door that replaced the garage door looks like it was there from the beginning, and the exterior trim blends perfectly with the house, with the added benefit of being waterproof. The communication was great all the way through the project, from start to finish. I would absolutely use them for any future remodel!"

Install Boiler questions, answered by experts

Coolant and antifreeze are technically not the same thing. The difference between the two is the ratio of water to other chemicals. True antifreeze is mainly made up of either ethylene glycol or propylene glycol, while coolant comprises one part antifreeze and one part water. However, the terms coolant and antifreeze are often used interchangeably, even by pros.

All modern boilers are condensing boilers because they’re the most efficient type. Instead of extra heat leaving through the flue, these boilers trap the heat and use it to heat the house. Whether you choose a combi boiler, system boiler, or regular boiler, you can opt to get a condensing system. If you have an old boiler that’s not a condensing boiler, it’s a good idea to get an upgrade.

Costs range from $3,000 to $7,500, depending on system size and efficiency.

It is almost always more affordable to repair a radiator than it is to replace one. The average radiator repair cost is around $150, and it’s typically about ten times as expensive—around $1,500—to replace a radiator. A repair usually takes under an hour, too, while a replacement can take several hours, making it less of a time commitment to repair one.

Installation costs range from $4,000 to $12,000, depending on unit size, efficiency rating, and labor.
