"These two gentlemen showed up everyday and on time with a smile on their faces. Yuni talked me through every step of the conversation process and was easy to work with. A Generous amount of care and professionalism went into my project. Their pricing will be hard to match for any of the big companies. I strongly recommend Dry Summer Waterproofing to anyone with crawl space problems like I had. They offer many other services that I will be using them for the future for."

"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

Thankfully, you do have a few sump pump backup options in case it fails. One option is a battery-powered backup sump pump. Another option is using a portable backup generator as a power supply for your sump pump. Unlike a battery-powered backup which has limited power, a generator can run around the clock for as long as you need it. 

Or you can opt for a water-powered backup pump, which uses your home’s water supply as a source of power. However, this may not be the best option if you find your house frequently has low water pressure.

Due to the nature of basements, some level of waterproofing is necessary to prevent water from seeping in and causing damage. Some definitive signs that your basement needs waterproofing measures or needs existing waterproofing measures need to be updated include:

  • Water in your basement, including damp walls or puddles on the floor

  • Mold spots in your basement

  • Musty smells or odors

  • Warped doors or walls

  • Cracks in walls

  • Insect issues, such as cockroaches and termites

The best way to ensure the ground next to your home’s foundation drains properly is to divert water away from it as much as possible. While a flood wall can stop water from entering the house, gutters and spouts can help direct rainwater and melting snow away from the foundation. Keep your gutters as clear as possible from dead leaves and other yard debris so they can effectively divert water from your house. Add extenders to the spouts so the water runs out and away from your home, not into the surrounding soil.

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.

The most cost-effective foundation repair is using masonry patches and sealants to seal foundation cracks and offer some support to prevent further damage. These methods are used to fix minor foundation cracks quickly. However, they’re not suitable as a long-term solution, and they only offer minimal stability. On average, masonry patches and sealants cost $500, but a sealant like an epoxy crack injection can total over $2,000. If you’re handy and only looking for a temporary solution until you contact a local foundation repair contractor for a more permanent one, you can save hundreds by DIYing this repair.
