"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!"

"Josh and Luis and their crew from Moisture Solutions did a professional job in my crawl space area sistering joists and repairing an outerband beam. They were prompt and always kept me informed of when they were coming and the progress of the work they were doing. They cleaned up the job site and on top of that they were pleasant, respectful, and friendly. I would hire them again without hesitation! They deserve a 5 star review!"

Basement Waterproofing FAQs, answered by experts

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.

If you set up a dehumidifier, it will usually dry out your wet crawl space within 12 to 24 hours. Once the space is dry, it’s a good idea to take preventative measures to keep it dry. These include installing a French drain or other exterior foundation drainage system, installing a sump pump in the crawl space, and installing a vapor barrier in addition to leaving the dehumidifier running.

“Basement waterproofing” sometimes refers to applying a waterproof sealant to basement walls, in which case you would use a waterproof paint, often made of latex. However, there are many methods you can use to waterproof a basement, including exterior drainage systems, interior drainage systems, dehumidifiers, and more. As such, the materials you use can vary depending on the methods you use.

It’s not the number of weep holes that should be of concern to builders but rather their spacing. Weep holes are usually spaced anywhere between 16 inches on center when using round tubes or wicking materials and 24 inches on center when using open-head joints. This is a more conservative spacing than the 33-inch maximum spacing on center that’s mentioned in the International Residential Code. All in all, the total number of weep holes a brick exterior should have will depend on the size of the structure.

Signs include persistent dampness, mold or mildew presence, musty odors, and visible water stains. If any of these occur, it is advisable to contact a professional for an inspection.
