"They had to take out a portion of my front wall which was not planned on, and the conic quality of the concrete was not as good as I thought it should be they destroyed the brick wall that they said they would be able to save and I think they also damaged an additional plumbing line, which I’m going to have to have repaired But we did get the leaking stopped, which was the big part of the problem they had to dig up the entire front foundation down to the 8 foot footer and re-waterproof the wall put in a French drain system and a new drainage system for the gutter and a sump pump"

"They leveled our sagging floors beautifully and installed a drain system with a sump pump to address basement flooding issues. All was done with punctuality, precision, and professionalism. Additionally, the price was very reasonable especially compared to competitors. Highly recommend."

"Mr Rooter called almost immediately and was at my home in less than 1 hour. Mr Rooter's technician Chris identified, cleared, and verified the blockage very quickly. After clearing the blockage, Chris set up a followup visit for the following week to pump out our septic tank and install a clean out fitting. We were very satisfied with all of the work."

"From start to finish working with this company was a wonderful experience! DJ was our point of contact and he is very professional and knowledgeable. He ensured we were adhering to city coding as well. The team worked efficiently and our patio looks better than we could have imagined! They noted holes in our underground drain spout and purchased us a new one during the patio install! They went above and beyond and we could not be happier with the results! Highly recommend this company and all employees."

"It took two days to tear out the old insulation under the bottom floor and install encapsulation in the whole crawlspace. Nick and his crew did quality work getting the job completed. They also patched holes in the foundation, hauled off all the old, dirty insulation and torn vapor barrier. All-in-all a very accommodating crew."

"We would highly recommend Sampson Concrete. Gideon made multiple trips to our home to help us determine the best design for our projects. The team arrived on time and were very professional. They took additional care to repair a French drain that had collapsed before pouring our patio. We had multiple projects today and are exceptionally happy with all of them. We will be hiring them again."

Foundation Drain Installation FAQs, answered by experts

A sump pump is one of the most common ways to get excess moisture out of your home, but it’s not the only way. If your home doesn't have a sump pump, other options to get excess water out of the basement include trash pumps, submersible pumps, service pumps, and hand-crank pumps. However, it’s worth calling a pro in to assess your situation and potentially install a sump pump for you.

Ideally, your sump pump discharge should run down a natural downhill slope 10 to 20 feet away from your home’s foundation. However, if your property is naturally flat, that might not be an option. Instead, you may be able to discharge it into a neighborhood storm drain or a nearby creek or pond. If that’s not possible, consider burying it underground.

Sump pumps remove excess water from the lowest point of your home, which prevents flooding. When a sump pit fills with water, a sump pump pushes that water outside of the basin and into an exterior discharge pipe. From there, the water flows away from your home, so it doesn’t damage your foundation.

Installing a battery backup for your sump pump is recommended, particularly if you live in an area with frequent power outages or severe rainstorms. A sump pump requires electricity to function, and a battery backup ensures it can continue to move water out of your home if the power goes out, providing crucial protection against flooding. Additionally, frequent power outages can create electrical surges that might damage the sump pump's motor. A battery backup system offers an additional layer of protection, ensuring your basement stays dry.

The cost to install a new sump pump, including materials and professional labor, typically ranges from $1,000 to $3,000. The average cost is often cited between $1,200 and $2,500. Several factors influence the final price, including the type of pump, the complexity of the drainage system, and the installation location. For instance, installing a sump pump in a basement may cost around $1,200, while a more complex installation in a crawl space can cost an average of $3,900. It is important to hire a licensed professional for the installation to ensure quality work, which can impact the pump's lifespan and warranty. Note that these costs are for a new installation; replacing an existing unit is less expensive, typically costing $308 to $748.
