"Paul Swann evaluated our foundation problem and referred us to an engineer who provided a detailed repair plan. Unfortunately, the nature and scope of the proposed repair plan was outside the parameters of what Northern Basement System's themselves could provide. We appreciated their honesty and have been looking for a contractor to take on the project."

"Just finished a visit with Foreman Doug and his crew, Devin, Sean, and Mason. Waterproofing the basement and super sound and solid work! Doug was professional and very good at keeping me in the loop with the project over the 3 day visit, and created a solid system that we are confident will keep water out of the basement forever. Above and beyond as well with problem solving when having to find solutions to fit our basement layout, all with a solid financing option/great price and 5 year warranty/ yearly inspection plan. If you are stuck with water in your basement, get Groundworks working for you ASAP!"

"They replaced a pipe for me in my basement. They came when they said they would, charged what they said they would, and finished up in the time he said he would. I'm very happy with them and wouldn't hesitate to hire them again. The one down fall is the shiny new copper pipe is so pretty, it's a shame it has to be in the basement where no one can see it !"

Basement Waterproofing FAQs, answered by experts

It depends on what caused your basement flooding, the extent of the problem, and the risk of the flood continuing. If your flood is coming from a septic system or sewer line, breathing in the sewer gasses can be dangerous, so you should vacate. If the flood occurs from an ongoing natural disaster, relocating to a safe area might be wise. If you just have a plumbing leak or rainwater coming in, you can likely stay in the house if you don’t have electrical lines down there, but make sure you call in professionals to fix the issue immediately.

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.

In most climates, contractors recommend closing your crawl space vents in winter. Keeping them shut protects your crawl space from freezing temperatures, pests, and cool breezes that can lead to chilly floors in your home. However, it's often best to speak with a local crawl space team about your specific design and its relationship to the winter season.

Although the two terms are closely related and often used interchangeably, pier and beam foundations and crawl spaces are different things. A pier and beam foundation is made up of concrete piers and wooden beams and creates a space under the home known as a crawl space. There are several types of foundations that create crawl spaces, often collectively known as “crawl space foundations,” but the crawl space itself is separate from the foundation. 

Covering the dirt floor in your crawl space with a vapor barrier helps insulate the space and improve the air quality in your home. It protects your crawl space from pest infestations, excess moisture, and mold growth. It also makes the crawl space less dusty, which means there’s a lower chance of dust mites breeding and causing allergic reactions in your home.
