"Fantastic! Still so happy about how everything went and how professional and knowledgable Sean was and what a pleasure he was to work with. We have been busy transforming a dank, disgusting old fieldstone foundation basement that had a variety of water issues into usable space. Between creating a lapidary work area for our son, an art area for me and some play area for our grandkids, we have been busy and so glad we called Century. Not only did Sean do the job right, well and fairly, he was flexible and ____ when we discovered we had an issue with the lobby columns. We were also very impressed with the people who worked for Century, such hard workers, polite and efficient. I have referred Sean and Century to many people already and would use his services again if the need arises."

"Bob and his crew were great! They installed a sump pump and drain in a part of my basement that had water for the chest time in 25 years. They also checked and repaired all my gutter leaders to make sure any clogs could be easily accessed. I highly recommend them!"

"Had basement french drains installed. Communication after the inspection/estimate was excellent. Gave me a start day and they arrived on time to get the job started. They protected my hardwood floors and thoroughly cleaned the floor once they were done. Time will tell if There are any problems with the drains."

"I can't say enough good things about American A-1 Waterproofing. Roland and his team were amazing. I had originally opted to go with another contractor to install a French drain and sump pump, but after exposing the foundation, they got spooked and said they wouldn't perform the work. Roland came by and assured me his team could get the work done and they did not disappoint. Through the initial estimate, permitting, construction and final sign off, Roland and his team were communicative, prompt, clean, and extremely professional. It was an absolute pleasure to work with them!"

"Went great, let me know that as my piping interconnects with my neighbor's (row houses dating to the 1940s), he couldn't actually snake the bathroom sink. That was after he looked in my attic and my neighbor's attic to see if he could gain access to the vent pipe from above. Did snake the tub - which is now draining much better. In addition to the snaking, he recommended and had on hand a bottle of enzyme declogger for the sink - hopefully that works!"

Foundation Drain Installation FAQs, answered by experts

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

Yes, many contractors offer warranties for their work. Confirm terms before starting the project.

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.

In most cases, yes, because the large majority of basements leak or will have moisture issues at some point, and waterproofing methods can mitigate that risk or eliminate it entirely. Plus, water and moisture issues can be quite problematic, as they can lead to mold growth, rotting of building materials, structural damage, poor indoor air quality, increased electric bills, and other problems.

Some sump pumps are powered by water rather than electricity. Water-powered sump pumps generally use one gallon of city water to pump out two gallons of water from its basin. Therefore, if you're looking at a potential 10,000-gallon flood, your sump pump will need to use 5,000 gallons of city water to prevent it.
