Why does a Bangor basement need a sump pump?
Central Maine's water table rises with spring melt and fall storms. Water that reaches the footing has to go somewhere. A sump pump is the part of an interior drainage system that actually removes it.
We install the basin, pump, check valve, and discharge line as one system. The line slopes away from the house to a pop-up emitter, dry well, or daylight outlet so water cannot run back or freeze in the pipe.
Homes already on a perimeter drain often only need a better pump. Homes without drainage get both. See basement waterproofing for the full system.
How do we size a pump for a Central Maine home?
Most Bangor and Hampden homes are well served by a 1/3 to 1/2 horsepower pump. A high water table, a large footprint, or heavy spring inflow needs more capacity.
We size the pump to the water your basement actually takes on. Guessing from horsepower alone is how undersized pumps burn out.
Battery backup and alarms
The storms that push the most water in are the same storms that knock out power. A battery backup keeps pumping for hours. An alarm tells you when the primary pump has failed.
Replacement and maintenance
Most pumps last seven to ten years. If yours runs constantly, cycles loudly, or is older than that, have it checked before the next melt. We replace failed pumps and service existing systems.
Signs you need a new sump pump
- Water pools on the basement floor after rain or snowmelt
- You run a wet-vac every spring
- The existing pump cycles constantly or not at all
- The pump is more than seven to ten years old
- There is no battery backup for storm outages
Leaking foundation cracks should be sealed at the same time so the pump is not fighting an open wall. Foundation crack repair and exterior French drains keep water from reaching the basin in the first place.
What does sump pump installation cost in Maine?
$1,500–$4,000
Typical range
A typical Maine sump pump installation, including the basin, pump, check valve and discharge line, lands in this range. Battery backup systems, a second pump or tying in new perimeter drainage move the price up.

“I've used Nick for all of my insulation and waterproofing needs and he's never failed me. Always on time, always polite, always a good price. I have nothing but amazing things to say about him and his team. We recently got our house re-insulated and it cut more than half of our heating bill.”
Sump pump installation questions from Bangor-area homeowners
How do I know if I need a sump pump?
If water pools on the basement floor after rain or snowmelt, if the walls stay damp, or if you already run a wet-vac every spring, you need one. A sump pump is the part of an interior drainage system that actually removes the water.
What size sump pump does a Bangor home need?
Most Central Maine homes are well served by a 1/3 to 1/2 horsepower pump. Homes with a high water table, a large footprint or heavy spring inflow need higher-capacity pumps. We size the pump to the water your basement actually takes on.
Should I get a battery backup?
Yes. The storms that push the most water into your basement are the same storms that knock out power. A battery backup keeps pumping for hours without electricity, and an alarm tells you when the primary pump has failed.
How long does sump pump installation take?
A pump and basin installation is usually finished in a single day. If we are also installing perimeter drainage to feed the pump, plan on two to three days.
Where does the water go?
The discharge line carries water outside and away from the foundation, to a pop-up emitter, dry well or daylight outlet. We slope and place it so the water cannot run back toward the house or freeze in the line.
How often should a sump pump be replaced?
Most pumps last seven to ten years. If yours runs constantly, cycles loudly, or is more than ten years old, have it checked before the spring melt. We offer replacement and maintenance for existing systems.
