"Dan was here this morning, showed him where water was leaking in over our slab and ruining the flooring in the master bedroom. He gave me the full range of possible remedies, from installing a eaves gutter on the roofline outside the bedroom to a full (very expensive) sealing of the entire exterior foundation. And actually recommended that we start with the gutter (which I can do myself) and then monitor the area next rainy season and see if that fixes the problem. No pressure to hire them or spend big $$, just good advice. Couldn't have asked for more. Highly recommended- this is real service!"

"I returned home from a trip and found water all over my downstairs bathroom and adjoining shed. It was late afternoon and I called Western Rooter who agreed to come out first thing the next day, I had a pretty sleepless night. Rene showed up the next day and assessed the situation and started clean up. Tony soon joined him and the two worked all day until after dark and helped me with cleanup and putting things right. They explained to me what they were doing and why along the way. I felt they charged a fair price. I am so grateful for their service and highly recommend Western Rooter."

"We worked with Ali (sales manager) and Tony (project manager), who took the time to design a project that made sense for our property and our budget, made a number of suggestions and recommendations and were never pushy or tried to "sell" us on something. The crew really went above and beyond to provide top quality workmanship and overall we were in very good hands. Highly recommended!"

"Joseph is amazing. We have used him many times for years for multiple home projects including remodeling a bathroom, new siding on the house, new roofing, plumbing repairs (and emergencies). He has always responded quickly, his work has been excellent, the site is always left immaculate, his crew are always on time and very pleasant. Joseph's work is outstanding and we have never had any issues. He has helped us out fixing issues that predated him also promptly and done to only his high standards. We can not recommend him high enough and will use him for many years to come."

Basement Waterproofing questions, answered by experts

Permits may be required for major repairs, structural work, or electrical and plumbing restoration after a flood. Check with your local building department to determine permit requirements and associated fees for your flooded basement cleanup project. Obtaining the correct permits helps ensure work is done safely and up to code.

The most flood-resistant materials you can count on in a flood scenario are concrete, closed-cell insulation, foam insulation (also known as expandable foam), pressure-treated wood, marine-grade plywood, and ceramic tile. When a material is flood-resistant, it can withstand direct contact with floodwater for at least 72 hours without being significantly damaged.

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

If foundation problems are not fixed, they will likely worsen over time, leading to more complex and expensive repairs. Neglecting a damaged foundation can cause a range of issues, including:

  • Structural Damage: Minor problems like small cracks can escalate into major structural issues. This can damage the house above the foundation and, in severe cases, lead to foundation walls caving in or a total collapse.

  • Water Damage and Pests: Moisture and water intrusion can cause flooding, mold growth, and pest infestations.

  • Health and Safety Risks: Mold can lead to poor indoor air quality and other health risks, while structural instability poses a significant safety hazard.

  • Reduced Home Efficiency: A compromised foundation can negatively impact your home's energy efficiency.

To avoid these escalating problems and costs, it's best to hire a foundation repair company to address any issues as soon as you become aware of them. The earlier problems are discovered and fixed, the lower the repair cost will likely be.
