"Vincent knows the cement business. I learned a lot from him. He replaced old cement floor and driveway. He works hard for his customers even weekends when circumstances dictate. I plan to hire him again to install patio stone when I choose the material and design."

"Elson and company did a great job replacing a garage apron and old patio block sidewalk. He was always prompt from the estimate to the final inspection. He kept in touch with me on his work schedule, even when he had to bump out the start date due to the weather. He kept to his word and quote. I'd hire him again without question."

Foundation Drain Installation FAQs, answered by experts

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.

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.

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.

In most cases, a crawl space will not dry out on its own unless the moisture comes from an uncommon flood and isn’t expected to be a recurring issue. For most homeowners, moisture problems in the crawl space will only continue to get worse over time, so addressing the underlying problem with gutter systems or a foundation drainage system and setting up a preventative solution like a dehumidifier is necessary.

If you hire a professional, installing a new sewage ejector pump costs $850 to $3,500, or an average of $2,300. Otherwise, if you handle the installation yourself, you can expect to pay $500 to $1,000 for the sewage ejector pump, permits, and other supplies required for this DIY project.
