"I hired this company to design my backyard landscape and they did a fantastic job. The designer was creative and came up with a beautiful plan that incorporated all of my ideas. The installation process was seamless and the team was professional and efficient. I now have a backyard that I can be proud of and enjoy all year round. I highly recommend this company for anyone looking to enhance their outdoor space."

"I highly recommend Groundworks for foundation concerns. They were very prompt with returning my call and providing a free inspection. I had concerns for my 103 year old home, especially a section of the foundation. Their Inspector, Bob Bloom, arrived on time, was professional and experienced, took time to answer all my questions (thank you for not rushing), and provided me with useful feedback on my foundation and options for repair. Bob gave an honest assessment with no sales pressure. Although I decided to defer foundation work at this time, I will definitely use them in the future."

"These guys are the best. Did a partial home repipe of both the water and drain pipes. Other plumbers tried to upsell us by replacing newer pipes and the water heater. Ray and Alex just did the repiping that was necessary. Excellent communication, friendly and on time. Even worked in tough, rainy conditions. Ray owns his own business and takes pride in his work. Recommended him to all my neighbors."

"Enriquez and his crew actually went above and beyond the original scope of work. Although he decided to replace more of the sidewalk concrete than quoted, he held the original price. Quality of the finishing was excellent as was the communication. Many positive comments from neighbors. I'd hire them in a wink if I needed more work."

"We re-did our driveway, front paths, side yard & backyard, making an entirely new look. eLite did a good job of making adjustments & gave expert advice. We even did a rather unusual path: we made a bridge over a dry creek bed. The entire project was completed in record time, with a very experienced crew. We're happy with the outcome & highly recommend."

"Joseph was on the job when he said he would be here. He is knowledgeable about the issue I presented, but did not try to oversell me on the job. He did notice that an electrical outlet could be improved with not a lot of time or money and which made my system safer. I would definitely hire Joseph and DIvine Electric again when I need them.

Foundation Drain Installation FAQs, answered by experts

The best basement waterproofing method depends on the specific issue causing the water intrusion. For minor problems, simple solutions like installing a properly functioning gutter system to direct runoff away and grading the soil to slope away from your foundation can be effective.

If you have more significant water problems, the solution will need to be more robust:

  • For standing water on the basement floor, a floor drain or a sump pump system may be the best solution.

  • For water pooling around the foundation, installing an exterior French drain can intercept water before it reaches the basement walls.

Other effective waterproofing methods, which can be used depending on your home's specific needs, climate, and soil type, include sealing the interior walls, landscape alteration, installing interior drainage systems, and using a dehumidification system to control moisture levels.

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.

Several factors can impact the cost of waterproofing your basement. Some of the most common cost factors include:

  • Location

  • Square footage

  • Cause of the water leak

  • Type of foundation

  • Accessibility

  • Waterproofing method

  • Materials

  • Contractor experience and availability

  • Engineering reports, if needed

  • Structural and other repairs

  • Permits

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.

The least expensive basement waterproofing methods include grading soil away from your home, installing downspout extenders on your gutter system, and applying a waterproof paint on the interior of the foundation walls. Installing a French drain is a relatively inexpensive method if you do the work yourself, although it’s labor-intensive and can be challenging to install properly.
