"I want to recognize three young men who recently completed our basement work through Groundworks: Matt, Taylore, & Gavin. The work was thorough, clearly explained, & the finished product looks excellent. But the biggest positive was the crew. They worked incredibly hard every day on a physically demanding, messy job, yet remained professional, disciplined, & respectful. They took great care of our home, kept debris contained, & cleaned up afterward. Matt took time to explain the full system to us & went above & beyond to help replace insulation that had fallen, even though it wasn't part of the job. Taylore & Gavin were equally helpful, helping us salvage & store shelving materials and remove a few stubborn pieces we couldn't manage ourselves. I'm genuinely impressed by their work ethic, attitude, & pride in doing the job right. I would absolutely recommend Groundworks, but especially these three young men. They represented the company exceptionally well!"

Basement Waterproofing FAQs, answered by experts

A sewage smell in your crawl space is usually from a damaged or clogged pipe leaking sewer gasses or actual sewage underneath your home, but there are some other common causes. Moisture, from poor or damaged encapsulation or a malfunctioning sump pump, can harbor mold and bacteria, causing a musty smell. Pests can also get stuck in your crawl space and die, which causes a sewage-like odor.

In many homes, an unfinished basement is an ideal place for an in-ground pool. The concrete floors, protection against water damage, and access to the ground below your home make this a large contender. Speak with a local basement remodeling contractor to ensure your space is right for the large construction.

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.

It is better to have a crawl space that is tailored to the outside temperature, your needs, and the season. For example, it is much better to have a vented space when it’s very hot outside and your AC bills are sky-high. Conversely, when the temperature drops and humidity rises, it is almost always better to have your vents shut and covered if possible.

A vapor barrier can last over 20 years, but they are vulnerable to pests, flooding, and other natural disasters. If your home weathers a storm or is treated for any pest infestation, make sure to have a drywall pro come check the integrity of your vapor barrier. It’s also important to have a pro install a vapor barrier since improper installation can lead to tears or leaks in the barrier that shorten its lifespan.
