"The crew was absolutely amazing! Very impressed with how professional, polite, and personable they all were. The management and crews are top notch! Management answered all the questions I had, walked me through what steps they were going to take to get things done. Dustin was extremely thorough, knowledgable, and took time to explain the recommended systems. I will 100% be utilizing them in the future strictly based on the level of trust and quality he presented! His communication was fantastic, they always arrived on time. They were careful with the property, always cleaned up when they were done. I will absolutely hire them again to complete any future foundation/basement work and I will absolutely recommend this company without reservation or hesitation. They stand behind their work."

Basement Waterproofing questions, answered by experts

The process might take a few days to a week, depending on the method chosen, area size, and weather conditions. Some solutions, like simple interior sealants, may require less time.

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.

Costs depend on the area's size and condition, damage extent, and chosen method. A professional evaluation provides a tailored estimate based on specific needs.

As the first layer of water protection for your roof deck and the building materials below, underlayment is designed to prevent water damage, so it’s okay if it gets wet. However, you shouldn’t rely solely on underlayment for protection. If rain interrupts your roof project and you have all of the underlayment down, you’ll likely be fine, but you should install shingles over that layer as soon as possible, as long-term exposure can lead to water damage.

French drains and yard grading systems are two highly effective ways to fix standing water around the foundation. Since the French drain uses a perforated pipe covered by gravel, you won’t have to worry about water taking the soil away from your foundation. Meanwhile, yard grading levels out the ground to prevent water from gathering around your foundation.
