"Removed old fiberglass insulation that at one time was rodent infested. Removed old plastic ground cover sheeting. Installed new ground cover black plastic sheeting and new fiberglass insulation. This was in the basement crawl space in my 9-unit apartment building. Very satisfied with the work - they were very responsive to some follow up work - would definitely recommend ."

"They came in and put plastic on the floor and kept the door closed as as much as possible thus not letting heat out of the house. All the work after went smoothly i.e. quick and neat. Everytime I had a question, Andy stopped and answered every concern we had. He also guaranteed the water clogging wont happen and asked us to contact him on direct line if ever we have a problem. At the end, on request, he also explained to us where and how things work and where the water will go in future. Time was scheduled at 10 am. Andy and his crew came 1.5 hours earlier than the expected time without prior information which caused me to get up and rush to the door half awake. That was the only complain I had."

"Had Groundworks install a drainage system and sump pump in our home’s crawl space. Anthony and his crew, Jordon, Uriel, and James were Outstanding. It was a three day job. They were on time every day and worked their tails off each day. It was a muddy job in cramped quarters. They never complained. Anthony kept me updated on the progress they made each day. Anthony shared pictures of the job as it progressed. They cleaned up the job site each day. Anthony went over all the details at the completion of the job and answered all of my questions. The whole process was Great. From the initial inspection done by Kristy to the office staff and the installation. The communication was also Great. I highly recommend Groundworks for a complete and thorough job."

Basement Waterproofing questions, answered by experts

Methods include interior sealants, exterior excavation and waterproofing membranes, sump pump installation, and vapor barriers for encapsulation. Techniques vary based on the structure and severity of moisture issues.

Egress windows or doors are required in finished basements to meet safety and building codes. If your basement is unfinished and used as a storage space, egress windows are not required, but anything considered a habitable space must have an additional point of egress in addition to the stairs.

Proper drainage is the only way to ensure that your crawl space stays dry. Depending on your property and the extent of your issue, you might need to consider a gutter system, a French drain, or sump pumps to avoid and handle water and moisture under your home. Dehumidifiers can also help to prevent moisture from accumulating if you have a high-humidity environment.

Yes, it’s worth it to repair a crawl space foundation, even if the issue seems relatively minor. Foundation problems often get worse and more expensive to fix if you leave them untreated. Additionally, your entire home, from the framing and flooring to the roof system, relies on the foundation for even and level support. Issues with your foundation will almost always manifest as problems in and above your living space, so it’s important to find a solution.

Some disadvantages of crawl spaces are mostly regarding the air itself—moisture build-up and poor ventilation, which can cause problems both in the house and underneath it, even damaging the foundation itself. Crawl spaces are difficult to access and often invite unwanted pests during the hot summer months and the cold winter ones. These hard-to-seal spaces are also susceptible to water damage during periods of heavy rain or melting snow.
