"I called Gash Plumbing and they were here the next day. The guy was professional and worked really hard to clean and empty our septic tank. He went well above just placing a hose and pumping out. I will use them again."

"The service i received from Greggs Foundation repair was outstanding. They installed a sump as well as a new drain to prevent my basement from flooding. I needed help and i needed it fast. I sent them a last minute message on their Facebook page, they showed up the same day and went to work. I am very grateful for Greggs Foundation Repair for showing up when they did and i would recommend them to anyone having foundation issues."

"In 2013 I was out of town on a trip. My wife called in a panic because water was coming in through a crack in the basement wall. We had lived in the house for 20 years with no issues. Recently we had new sidewalks poured which disrupted the water flow from the house. This caused water to seep back into the foundation. The Leaky Cellar came the next day and provided a fair estimate and repaired. When I returned home I was very pleased with the work, timeliness, and price they charged. A less reputable company could have taken advantage of the situation. Recently we had the annoying water seepage in our stone foundation. The Leaky Cellar proposed various options to address the situation. They recently installed interior drains. The men were very professional and answered all my questions. For a messy job, they left the basement in good shape. I was very pleased with the work, price, and professionalism. I would recommend them to a friend."

"This company does it ALL! When we called to get a quote on few projects around our house we found out all other extra things they do. I was so impressed by the professionalism and quality work they do. We got our house waterproofed (had a private pool on the side of our house), few drains installed in ground, mudjacking (lifted our driveway and steps) and fixed our sump pump to drain correctly and more. Our foreman was extra awesome and they left the site clean as a whistle. We will definitely use them for our future projects and we already recommended them to our relatives. A1 is A+ in my book!"

Sump Pump Installation FAQs, answered by experts

Yes, it’s possible to install a sewage ejector pump outside rather than in a basement. However, there may be some extra steps involved, including running pipes from the inside to the outside of your home and digging (and re-filling) a hole for the basin. If you aren’t comfortable with this type of work, contact a plumbing pro to handle it for you.

If you have a self-cleaning washing machine but you’re still seeing lint, your water pump filter might be clogged. To clean it, you should unscrew the drain hose, then remove the water pump filter. From there, you can inspect it and clean it with warm water before replacing it. Check to be sure your washing machine is functioning by running a short cycle. 

In most cases, standard homeowners insurance policies do not cover damage from a sump pump failure or overflow. Coverage for water damage is often limited to sudden, unexpected events like a burst pipe that was not caused by negligence. To be covered for sump pump issues, you will likely need to purchase a specific rider, endorsement, or additional water backup insurance. If your insurer offers this type of coverage, they may require proof that your sump pump is regularly maintained.

Common problems include motor failure, clogged discharge lines, and float switch malfunctions. Regular maintenance prevents many issues.

Yes, a well-maintained sump pump can increase a home's value and make it more desirable to potential buyers; it does not lower property value. By protecting the basement from flooding and water damage, a sump pump provides peace of mind and can make the space usable for storage or as an extra room. For buyers interested in homes with basements, a working sump pump is a significant feature that adds value by ensuring the space is secure and less likely to flood.
