With a locally owned and operated company, you can expect friendly, personalized service. All Phases Green Services has been in business for over 20 years and offers great craftsmanship in woodworking, cabinetry, counter-tops and installations. We also specialize in tile installation and renovations.

"I would not recommend this contractor to anyone. I hired All Phases Green for a major kitchen renovation. They had done several projects for us before with good results and had been our go-to company for both small and large jobs. The kitchen started off well, and the company was responsive when design changes or unexpected issues came up. However, I noticed the owner’s helper was not meeting the standard I had come to expect from the owner—paint runs, debris in the finish, and sloppy mistakes that stood out even to me as a homeowner. I raised these concerns, expecting them to be addressed, especially since in the past, he was quick to fix any issue. While one of my concerns turned out to be a natural wood issue, instead of explaining that professionally, the owner replied with a condescending text. Shortly after, rather than taking accountability or offering solutions, he abruptly quit the job with another passive-aggressive text message, leaving a large portion of the renovation incomplete. No effort to resolve the situation—just gone. Abandoning a project because a client points out legitimate concerns is incredibly unprofessional. I am absolutely shocked he responded how he did after having worked with him for so long. If a contractor can’t handle feedback or stand behind their team’s work, they shouldn’t be in this business where client feedback should be welcomed. I trusted him, and it became clear what kind of person and business owner he is. I would not recommend this contractor to anyone."

Water Heaters questions, answered by experts

A leaking water heater could potentially last for a few weeks or months before you need to repair it. However, it's not advisable to wait too long. Once your water heater starts leaking, it's likely that the underlying cause of the leak is getting worse as time goes on. Without immediate repair, your water heater could fail. Instead of using a leaky water heater, you should turn it off and call a pro to fix it.

If your water heater is about to celebrate the big 2-0, you may want to consider sending it off to greener pastures. While the water heater may seem to be working well, any conventional, tanked water heater over 10 years of age is at risk of failure. If your water heater is 20 years or older, your best move is to replace your aging heater before it completely breaks down.

Often, the first issue you might encounter is a lack or loss of power—this could be caused by a tripped switch or a failed heating element. If your hot water is not producing enough power and its size is not the issue, you might need to replace one of its heating elements. A leaking water heater could be caused by tank erosion.

While many older homes don’t need hot water heater expansion tanks, they’re necessary in most newer homes and are required by building codes. These tanks are required by code in areas where there are backflow preventers or pressure regulators on the incoming water pipe between the public water pipes and the water heater. However, tankless water heaters don’t require expansion tanks.

Typically, only a high-efficiency water heater with an inducer fan can be vented outside the house. Otherwise, your water heater needs to be installed on the inside and vented through the roof. However, certain areas may allow a standard-efficiency water heater to be vented outside. Check your local building codes to be sure.
