"They did exactly what they said. After looking at the basement mudjacking, I noticed that they could have easily done some work to get their recently re-leveled floor to match with the rest of what was around the section they touched. Good work, but no extra effort."

"Jordan was awesome! He initially sent one of his guys out to check for some gurgling and sediment in our plumbing in the basement. They took a good look and found some grading issues with our pipes. Jordan followed up with me after and then committed to coming out himself to determine options. Throughout it all he was very communicative and extremely knowledgeable. We discussed some options and moved forward with the one that made the most sense. The issue was addressed and Jordan followed up later on to make sure everything was still good. Highly recommend Jordan and team dr.drain!"

Basement Waterproofing questions, answered by experts

A crawl space is an area under the house that provides access to plumbing, electrical, heating ducts, and other HVAC units. Its purpose is to create a buffer between the ground and the living area, helping with ventilation, moisture control, and access for maintenance or repairs. Crawl spaces are most often seen in houses in North America which are built on concrete foundations versus other parts of the world where buildings are constructed differently.

Basements are commonly converted into game rooms. The potential challenges you may run into include controlling moisture, working with low ceilings, limited natural light, and the need for additional electrical or HVAC work. Addressing these issues can add to the total cost, but it ensures a comfortable and functional space.

Home improvement grants are available for various groups, including individuals with very low-income housing, elderly people, older adults, and veterans. These grants can cover a range of needs, from accessibility modifications to addressing critical issues that may affect a resident's health or safety.

Many prevention methods can be used individually or in combination to waterproof your basement. Some of the most common waterproofing methods include:

  • Using dehumidifiers 

  • Silicate concrete sealers

  • Vapor barriers 

  • Baseboard channels 

  • Drain tile systems

  • Waterproofing paint

  • Drainage systems

  • Epoxy injection

  • Interior French drains

  • Exterior excavation and waterproofing

  • Cement waterproofing

  • Weep tiles

  • Liquid membrane

  • Sheet membrane 

  • Yard grading

  • Gutters and downspouts

Yes, water coming up from the floor should be treated as an emergency. If you're unable to either identify or stop the source of the water on your own, contact an emergency plumber right away. In addition to harming your flooring, standing or pooled water can lead to water-damaged concrete.
