"They did an excellent job of waterproofing our foundation, burying downspouts, and replacing a patio to guarantee drainage away from the house. Most of our interaction was with the crew foreman. He spoke good English, showed attention to detail, and did a careful, professional job even when the weather got so hot we found ourselves urging the crew to take more breaks. They were not the cheapest bid, but worth it for the skilled workmanship. This is the second project we have hired them to do, and I would recommend them for any work where drainage is important."

"We had a wet basement, so we had foundation work done, and a sump pump installed. The work was done in March, but we have waited until well into the rainy season to submit this review, so we could be sure there were no further water problems. Dan, Tony, and the men who assisted Tony were excellent! Dan told us the work would take four days, but they completed it in three. They dug up a small mountain of soil in the backyard while working on the foundation, and their clean up job was very clean. They also took special care to protect belongings when installing the sump pump. Thank you."

"Kap from Joseph Plumbing and Drain was great. I requested a quote Saturday morning and they came out within a few hours. We scheduled the work for Friday and they arrived on time, were friendly and professional, and did excellent work installing my new main water shut-off valve. Highly recommend."

"It went very well. Lal wore covid19 PPE and covered his shoes as not to soil my floors. He had to remove the toilet to unstop the drain pipe. He used an electric snake to clear the drain and replaced the toilet including re caulking. I'm very pleased."

"Excellent work! Arturo helped us originally followed by his amazing crew. Highly recommend this company. Arturo as consultant, Jeff as Project Manager and Hymie we’re all excellent. Our crawl space foundation was disgusting. This work should have been performed by earlier owners but it fell to us. We were tired of critters, cold floors in the winter, and moisture. Now we have a space under our house that is immaculate and dry. And, cracked wooden beams have been stabilized and a de-humidifier Installed that drains invisibly."

Foundation Drain Installation questions, answered by experts

Most sump pumps come with power cords that can be plugged into an outlet, but there are options that can be hardwired into a home’s electrical system. Either way, it’s smart to have a backup power supply in case the electricity goes out during a storm. That way, the sump pump can keep running and removing water from the sump pit.

Methods include interior sealants, exterior excavation and waterproofing membranes, sump pump installation, and vapor barriers for encapsulation. Techniques vary based on the structure and severity of moisture issues.

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 drain wastewater and solid waste into the municipal sewer system or a septic tank. For fixtures below this level, like those in a basement, gravity cannot move the waste upward. The ejector pump provides the force needed to pump the sewage up to the main line. Without one, wastewater from below-ground fixtures would back up, potentially causing a sewage overflow and flooding. If all of your plumbing is on the main floor or higher, gravity is sufficient and an ejector pump is not needed.

Costs depend on pump type, labor, and site-specific requirements like excavation or drainage lines.

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.
