"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

In nearly all cases, you are required to install a vapor barrier in your crawl space. However, local regulations will change based on the local climate and the crawl space's susceptibility to moisture. Even if a vapor barrier is not legally required, it is often a good idea to keep your crawl space dry.

No, your basement dehumidifier doesn’t need to be on 24/7. While it’s an excellent tool for tackling damp, musty air, especially in humid seasons, leaving it running nonstop can backfire. Over-drying the space can mess with your sinuses, warp wood, and even crack certain materials. Instead, only use your humidifier when moisture levels rise above 50%, and then give it a break when the humidity levels drop.

Whether to waterproof your basement from the interior or exterior depends on several factors, including your budget.

Exterior waterproofing is generally considered the superior method because it stops water at the source, preventing it from seeping into and damaging your basement walls. This approach offers the most protection, making it ideal if you use your basement for storage.

By contrast, interior waterproofing is often less expensive and requires less labor because the area is more accessible.

For maximum protection against water leakage and moisture, applying waterproofing measures to both the inside and outside is the best solution. However, if you must choose only one, stopping water from the outside is the most effective approach to preserve your foundation and prevent damage.

The most challenging part of finishing a basement is addressing moisture control. Basement waterproofing is an essential task that requires a professional’s skills and knowledge. If you don’t properly waterproof your finished basement, it’ll be vulnerable to dampness, water damage, and mold growth. Ensuring proper insulation and ventilation to combat these issues while meeting building codes adds complexity to your remodeling project.

A sump pump can remove excess moisture from under a house if standing water is present. Other ways to protect your crawl space from moisture include installing a vapor barrier, using a dehumidifier, installing insulation, and using a fan to dry the space. Finally, keeping your gutters clear of debris and positioning your downspouts away from the home’s foundation can prevent moisture from getting into the crawl space in the first place.
