"Excellent service. I had a sump pump system put in 10 years ago by Rescon. Never had any problems with it, worked great. This weekend with all the rain the pump stopped working. I called there emergency line and a service technician called me back in less than an hour. They were at my house in less the 2 hours fixing my pump. They did charge me an emergency dispatch fee for the service call but I guess that s expected on a weekend. Overall it was excellent service and I am very happy I chose this company."

"I finally got to build my dream garage to store all my tools and have a cool hangout on Friday nights with the boys n a couple coors. Chris came and did everything from the bathroom and the heating system. I will definitely be calling him back to add a mini split in the future. He was professional, punctual and clean. Very knowledgeable you can tell he cares about his clients."

"Adam and his team did an amazing job on completing a backyard fence for my family. He was hardworking and detailed with the work. Kept me updated through every step of the way from the permit process, ordering materials and check-ins as the build was happening. Our fence is great! He also completed a custom railing and gate to attach to our existing deck. Will definitely be using we do it all again for future projects."

Sump Pump Installation questions, answered by experts

Yes, it’s normal (and beneficial) to have a small amount of water in the bottom of your sump pit. It shows that your system is collecting groundwater, rain, and excess water from around your property—just like it’s supposed to. However, if the sump pit is always full, you might have a leak or a faulty sump pump.

If you notice any new sump pump noises, such as persistent clanging or gurgling, then you likely have a sump pump problem on your hands. Foul odors coming from the pump can also indicate problems. Additionally, if your unit turns on but doesn't pump water, you might have to address electrical problems. In any of these cases, it's a good idea to hire a professional to address the issue.

A sump pump's lifespan is typically 7 to 10 years, though the general range can be anywhere from 5 to 15 years. The specific type of pump is a major factor: pedestal sump pumps last an average of 20 to 25 years, whereas submersible sump pumps last between 5 and 15 years. While pedestal pumps are less expensive to service, they are also louder and more prone to clogging.

Several other factors influence longevity, including the pump's quality, usage frequency, and maintenance schedule. A high-quality pump that is well-maintained in a dry climate may last for two decades, while a lower-quality, poorly maintained pump in an area with a high water table or frequent flooding may fail in six years or less.

Regular maintenance, including annual inspections and tuneups from a professional, can significantly extend the pump's life. It is time to consider a replacement if your sump pump runs constantly, cycles frequently, shows visible rust or corrosion, or trips a circuit breaker. As a preventative measure, many homeowners replace their pumps every eight years. It's also worth noting that a manufacturer's warranty can indicate expected lifespan, and some home insurance policies may not cover water damage from a pump that is past its recommended replacement date.

Yes, you can add a battery to your existing sump pump. There are batteries available that can be plugged into your existing system; however, most battery backups come as a complete system and act as a replacement for your existing sump pump.

A sewage ejector pump is necessary if you have any plumbing fixtures, such as a bathroom, laundry room, or sink, located below the level of your home's main sewer line. Standard plumbing relies on gravity to move wastewater and solid waste to the municipal sewer or septic tank. However, for fixtures located below grade (e.g., in a basement), gravity is not sufficient.

The purpose of a sewage ejector pump is to actively pump this wastewater and solid waste upward into the main sewer line. Without an ejector pump in this situation, wastewater would have no way to exit and would eventually back up, causing a sewage overflow or flooding in your basement. If all of your home's plumbing is on the main floor or higher, gravity can handle the drainage, and an ejector pump is not needed.
