"I hired Fratt Plumbing to replace a water heater in my mother's home. Mr. Fratt was very professional over the phone and the price was reasonable. Although I was not present when the work was done, the report from my mother was very good. They showed up when they said they would and did the work they said they would do. They also replaced part on the furnace (for an additional charge). It's been a couple of weeks now and there are no known issues with the work at this point."

"I had a flood starting in my basement when my sump pump went out. Luckily, when I called Paul (of PP's Plumbing) he was able to come right over and swap it out before the water really became a problem. He was fast, efficient and fair. I would trust all of my plumbing to Paul."

"Two people, a young man and a young woman (I think he said that she was the secretary)
 arrived at the house a little bit late, I think because of the snow.
While he worked on the doors (2 doors & one sliding door) she was doing the caulking of the windows. My wife and I noticed that she applied some caulking on the same spot on each window. The caulking was always on the bottom part of the windows. We thought that since she was too short could not reach the sides or top part of the windows. When they left I checked the windows and noticed that there was no sign of caulk on the sides or top of the windows and very little on the bottom part of some windows. So, we don't think there was much improvement on the windows that she worked on.
The only positive thing is that two of the doors seem to have fewer leaks than before. 
The young man told me that he wanted to check the attic; I told him that we had the attic inspected last year and I was told that the attic had enough insulation. I personally went in the attic with the inspector last year and he showed me the marks that indicated that the insulation was sufficient and showed me how to read the marks to determine when to add more insulation.
The young man told me that the attic needed more insulation and that they could do it for $3000.00. I did not do it because, again, just last year I was told that the attic was OK.
The young man charged me an extra $20.00 for material he used on the sliding door.
At the end I felt that I paid $300 + $20 for an unlimited winterization but they only worked on 3 doors.
They worked for about 3 and 1/2 hours.
Next day I checked the sliding door and I had to put tape on the weather strip to keep it in place.
Also, the next day my wife noticed we did not have hot water. So, she thought the water heater was bad and called a company to fix it. When the company arrived they said that the water heater had been set to pilot. My wife told me that she remember the young man saying that he needed to turn off the water heater or move the control to pilot. So we paid this other company $125.00 for a service call just because Brand New Construction forgot to put the water heater back to the ON position.
So, what it was supposed to be $299 for Unlimited Winterization Home Package, turned out to be $444.00 ($299 + $20 +$125) for replacing the weather strip on two doors and one sliding door. I realized I could have done that myself and save at least $400.00.

Water Heaters FAQs, answered by experts

No, you’ll need to drain the tank before changing a water heater element, as the water heater element sticks through the side of the tank and uses a gasket to prevent water from pouring out. However, you don’t always need to drain it completely. If you’re only replacing the upper heating element, you can drain the tank until the water line is below the element. If you’re replacing the lower element, you’ll need to drain the whole thing.

Tankless water heaters heat water as it passes through the unit instead of storing heated water in the tank. Their ability to produce hot water on an as-needed basis makes them more efficient. However, they are generally more expensive than traditional units. Is a tankless water heater worth it? Most homeowners will save money with a tankless unit in the long run by using less energy.

The lifespan of a water heater depends on its type, usage, and maintenance schedule. Traditional tank-style water heaters typically last between 8 and 12 years, though the range can be as wide as 6 to 15 years. Within this category, gas models often last 8-12 years, while electric models may last 10-15 years. In contrast, tankless water heaters have a significantly longer lifespan, often lasting up to 20 years or more. Factors like heavy usage, hard water, and sediment buildup can shorten a unit's life. To extend its lifespan, it is crucial to perform regular maintenance, such as flushing the tank annually and scheduling professional inspections. If your unit is over a decade old and shows signs of rust, leaks, strange noises, or inconsistent heating, it is likely time for a replacement.

If your system is not vented properly, you could experience what’s called backdrafting. Backdrafting is when your ventilation system isn’t working as it should, and instead of releasing gases outside, they get trapped inside your home. 

Gas and propane water heaters create a few types of combustion gases, but the most dangerous is carbon monoxide. If there’s too much build-up of these gases inside your home, it can lead to carbon monoxide poisoning.

Water expands when heated and also when freezing. When water is heated, it expands by around 4%. For a full water heater, this is one of the main reasons malfunctions occur—the hot water has nowhere else to go but out. Due to the constant expansion and reduction in volume, it’s recommended (required in most places) that an expansion tank be installed.
