"I have had two issues since they installed the new sump pump and irrigation. Issue number one was water still getting passed the new concrete. The other issue is that the new concrete was not level at all which has caused issues with the new flooring I installed. However, their customer service is top notch and will work hard to take care of you."

"Being on the coast and close to wetlands, there is a ton of water accumulation in my crawlspace. Terra Firma had a ton of work to dig out the drainage trenches but they did a wonderful job! They had a large crew that tackled different projects to get it all done in 1 day. Everyone was professional and very friendly. I will definitely use them again for my continual foundation improvements."

"Jamison and his crew were absolutely awesome to work with. I would and already have recommended them! Once they started the job they worked until it was finished and cleaned up after. They poured 43 yards of concrete, with 50% of it colored and stamped for our driveway and patio. They were very meticulous around the screens and covered our home with plastic to ensure there was no splatter. They were also very meticulous with the underground drain system for our driveway. The kept us informed the whole way through so we knew what was happening and what to expect. Our slopped driveway turned out awesome and our patio is stunning!"

"I'm waiting to receive their proposal today, but when he came to see the project site yesterday, Dustin was professional, on time and very thorough in his assessment of the problem. I learned a lot about French drains."

Foundation Drain Installation FAQs, answered by experts

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.

Pooling or standing water in your basement should be cause for alarm and action. This indicates that there is a leak or a drainage issue, and until you repair the root of the problem, the situation will only happen again or grow in severity. It’s important to deal with water damage as soon as it occurs.

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.

Yes, it’s possible to install a sewage ejector pump outside rather than in a basement. However, there may be some extra steps involved, including running pipes from the inside to the outside of your home and digging (and re-filling) a hole for the basin. If you aren’t comfortable with this type of work, contact a plumbing pro to handle it for you.

Some questions you should ask before hiring a plumber or drainage installation company include:

  • Are you licensed and insured?

  • Do you have any customer testimonials I can read?

  • How do you handle unforeseen challenges that occur during the job?

  • Is your fee a flat rate or hourly?

  • Do you do the work, or do you have subcontractors?

  • Is everyone who does the work licensed and qualified plumbers?

  • Is cleanup included in the quote?

  • Do you offer a warranty or guarantee on your work?
