"The crew from Foundation Support Specialists, which included Hector Roman, Eddie Sanchez, Ricky Rodrigez, and Mark Willis, did a fantastic job installing piers under the stem wall between my garage and house, and also encapsulating and insulating the crawl space in my basement! They worked quickly and tirelessly to get both jobs done despite having to work in 95+ degree weather with no air conditioning. They were all very courteous and took great efforts to keep the areas they were working on clean of any debris. I will definitely use them again for any future foundation work, and highly recommend them for similar work for anyone needing these types of services."

"We started a DIY to replace a toilet. We saw the builder’s plumber did a bad job on the flange. No screws to hold it down but a lot of glue. We had 3 plumbers come in to review and give us their input/quote. John explained what he wld need to do. The quote was reasonable. Best part, he wld not need to bust up the tile or go underneath the foundation. We are very pleased with his work along with his apprentice. We will recommend and use them again. Thank you."

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.

Waterproofing or encapsulating protects against moisture, preventing mold growth and structural damage. These services also enhance energy efficiency and improve air quality by keeping humidity levels in check.

Anything having to do with the structure of your home, such as raising the ceiling, is usually the most expensive part of finishing a basement. Another project component that could be a surprisingly high expense is adding an exterior entrance. 

The cost of a walkout basement can be anywhere from $5,000 to $35,000.

Several factors can impact the cost of waterproofing your basement. Some of the most common cost factors include:

  • Location

  • Square footage

  • Cause of the water leak

  • Type of foundation

  • Accessibility

  • Waterproofing method

  • Materials

  • Contractor experience and availability

  • Engineering reports, if needed

  • Structural and other repairs

  • Permits
