"Called company on Monday and got an appointment for an inspection on Wednesday. That following Monday, the technician arrived and went through each step is sealing off the concrete foundation to the water leak. The fix worked well and was put to the test with the recent record rains. Not one drop of water came into the basement."

Customers say: Quality work

"Very pleased with the prompt, friendly service. Very efficient and told me exactly what had to be done and what it would cost in advance. The old, limed up water heater had to be a bear to haul up and out of the basement. It gives me peace of mind knowing that the appliance was installed correctly by an experienced plummer and that it will last for many years to come."

"During heavy rains we would have water flowing freely in our basement. We hired Everdry over ten years ago to fix the problem. Their workmanship and attention to detail has proven we made the right decision. We haven't had any issues with water in our basement. When the sump pump kicks on we know the drainage system is working as it was designed to. We appreciate the job Everdry did in keeping our basement dry. We wholeheartedly recommend them for you waterproofing needs."

Basement Waterproofing FAQs, answered by experts

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.

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

Yes, these services often increase home value by preventing moisture-related issues and enhancing the usable space in basements or crawlspaces.

Yes, it is possible to over-dehumidify a house by removing too much moisture from the air. This can create an overly dry environment that negatively affects those with respiratory or skin issues, and may cause your skin, hair, and sinuses to feel dry. However, this is unlikely to happen with most modern dehumidifiers, as they are equipped with moisture sensors and adjustable settings. These features allow the unit to pause automatically when the desired humidity level is reached, preventing the air from becoming uncomfortably dry. In contrast, older or more basic dehumidifiers left running for too long could potentially over-dry the air. To avoid this, aim for a balance between removing excess moisture and maintaining a comfortable environment. You can often monitor your home's humidity levels using a modern thermostat for guidance.

Plan on cleaning your crawl space at least once a year, though twice a year is ideal. During the cleaning, remove any debris or dust and check for potential issues like pest infestations or water damage. The sooner you catch these issues, the easier (and cheaper) it will be to fix them.
