Having had bad experiences in the past, I can be pretty wary of contractors, but I need not have worried with Riley! We were in a no-heat situation during cold weather and he was able to move things around and get to us within a few hours. During the diagnostic, he insisted I was present as he...

Hired Andrew to replace and install new class 4 shingles on my garden shed. Him and his helper were very fast and professional with install. After the install they did a very thorough clean up of the jobsite! Would recommend and hire for any future projects.

Owner Jerry Boyd was professional, timely, and meticulous in his work. Jerry was open about the process of the bathroom remodel from start to finish. Especially like that he will not install â cheapâ items. Everything done to our liking. Highly recommend Jerry!

A+ It went great! Doug was early, and already had the out buildings inspected before I arrived. This left me time to focus on the home, which was the bulk of the inspection time. I really appreciated that, since I was on my lunch, and I am more concerned about the home than the other buildings....

The process went fairly well. Only hitch was it started to rain when they had the roof tore off. They had started to install the new roof at the time. They were very quick to get tarps up! So far we are very happy with the work and have gotten many compliments on how the house looks.

"Our technician, Dameyan Jackson, called the night before the day of service to let me know the time that he would be here to service our system. On Friday, he called to let me know that he was available to come earlier than scheduled, if I would like. He arrived shortly after the phone call, came in and quickly recognized that the pump had failed. He was very knowledgeable and professional. I was very pleased with his service and look forward to him returning to install a new pump."

"Goettl & Verbracken did a very competent job for us under difficult conditions in an older home. Working side by side was helpful for both parties, as questions always come up. Location of installed flex gas line (next to and in the same opening as the metal dryer vent) was not anticipated. I drilled a new hold with spade bit and extension and rerouted the gas line. Otherwise, we are happy with the work done and would hire again!"

Sump Pump Installation questions, answered by experts

No. Sump pumps have different capacities, which refers to the volume of water that they can remove. They also come in various horsepower ratings, which measure the size of the pump’s motor. For many homes, 1/3 horsepower is enough. But if you live in an area that floods often, you might need a more powerful model.

3/4 HP is stronger than 1/2 HP. Horsepower measures how much weight can be moved and how fast, or the power needed to move 550 pounds one foot in one second. 1 HP equals 550 foot-pounds per second, so the higher the horsepower, the heavier the load it can lift. While 1/2 HP is a standard, powerful option, 3/4 HP has the extra strength to handle heavier, larger doors with ease.

Sewer ejector pumps need to be cleaned at least once a year by a professional. You shouldn’t attempt to clean it yourself because it can release sewer gasses that are toxic to humans and can be fatal. But to keep the system as clean as possible between professional inspection and cleaning services, be sure to only flush human waste and toilet paper. Avoid flushing items that can clog the system, like paper towels, grease, oil, or menstruation products.

A sump pump battery backup can typically run for 6 to 24 hours. The factors that affect its runtime include the battery capacity and pump usage.

When purchasing your backup system, take these factors into consideration to determine which system is best for your home. If you live in an area with frequent and long-lasting power outages, consider a longer-lasting backup battery.

A small sump pump running infrequently uses an average of 10 kilowatt-hours (kWh) of electricity per month. The average cost for electricity is $0.171 per kWh. The size and use frequency affect how much electricity it uses. Sump pumps average one-third to one horsepower (hp) motors. One hp is equal to 745.7 watts. Watts multiplied by the time your pump is running divided by 1,000 equals your average kWh. Multiply kWh by your average cost of electricity. In areas with high rain or a marsh basin, the average cost can be as high as $15-$25 a month.
