Waterproofing FAQs

The cost for waterproofing services can vary widely depending on the scope of the project and the method used. On average, homeowners in the U.S. spend between $2,000 and $7,000 for professional waterproofing services. Here’s a breakdown of common services:

  • Basement Waterproofing: $3,000 to $10,000, depending on whether exterior or interior systems are used.
  • Foundation Crack Repair: $500 to $4,000, depending on the size and extent of damage.
  • Crawl Space Encapsulation: $1,500 to $15,000, based on the size of your crawl space.
  • Exterior Waterproofing: Starting at $5,000 and can go up to $20,000.

It’s important to have an inspection done to get an accurate estimate tailored to your specific needs.

Signs that your home might need waterproofing include:

  • Wet or damp basement walls or floors;
  • Musty odors in the basement or crawl space;
  • Visible mold or mildew growth;
  • Standing water around the foundation after heavy rains;
  • Peeling paint or efflorescence (white, chalky residue) on walls;
  • Cracks in the foundation or walls.

If you notice any of these symptoms, it’s a great idea to schedule an assessment with a waterproofing professional to avoid more severe damage in the future.

In many cases, waterproofing services are not covered by standard homeowners insurance policies. Insurance generally covers damage caused by sudden and accidental events, like a burst pipe, but not damage from gradual issues like foundation leaks. However, if flood damage is an issue in your Onset home, you may want to look into a separate flood insurance policy. Be sure to check with your insurance provider to understand your coverage and plan accordingly.

Waterproofing Pros offer a wide range of services designed to protect your home from water damage. These include:

  • Basement waterproofing: Both interior and exterior systems.
  • Foundation repair: Crack injection, structural repairs, and sealing.
  • Crawl space encapsulation: Moisture barriers and drainage systems.
  • Sump pump installation and repair: Keeping basements and crawl spaces dry.
  • Exterior waterproofing: Protecting the foundation from the outside.

They also offer inspections and consultations to recommend the best waterproofing solutions for your home.

The timeline for waterproofing depends on the scope and complexity of the project:

  • Basement waterproofing or interior systems: Typically 1–3 days.
  • Foundation crack repairs: Can be completed in 3–8 hours for minor cracks.
  • Crawl space encapsulation: Most jobs are completed in 1–4 days.
  • Exterior waterproofing: May take 3–10 days due to excavation and additional labor.

Your waterproofing contractor will provide a timeline during your consultation, taking into account the size and specific needs of your home.

To choose the right waterproofing contractor, ask the following questions:

  1. Are you licensed and insured? 🛠️
  2. What warranty do you offer for your services?
  3. Do you have references or reviews I can see?
  4. What methods do you recommend for my home's waterproofing issues, and why?
  5. Does your quote include all materials, labor, and cleanup costs?

Getting clear answers ensures you’re working with a reputable company and staying informed about the process.

Most waterproofing work is minimally disruptive, though the level of disruption depends on the type of project:

  • Interior waterproofing systems involve working inside the home, which may limit access to certain areas for 1–3 days.
  • Exterior waterproofing requires excavation around your foundation, which can be more disruptive to landscaping but doesn’t impact the home’s interior.
  • Crawl space encapsulation usually affects your crawl space access but won’t interfere much with daily life.

Your contractor will let you know exactly what to expect and how to prepare for the work.

Permit requirements for waterproofing projects vary by city and state. In some areas, exterior waterproofing or significant foundation repairs may require permits. For homeowners in Onset, it’s essential to check with your local building department to determine what’s needed. A reputable company like Waterproofing Pros will often handle the permitting process for you. For detailed codes and regulations, visit your city's website or check out the International Code Council's FAQ.

While no solution can guarantee 100% waterproofing forever, many professional systems are long-lasting and highly effective. For example:

  • Interior systems often come with lifetime warranties against water intrusion into basements.
  • Exterior waterproofing can last decades when properly installed.
  • Crawl space encapsulation effectively prevents moisture issues for years with proper maintenance.

It’s crucial to maintain your waterproofing system (e.g., servicing sump pumps regularly) and address any new issues promptly to ensure the longevity of the solution.

Be cautious of these warning signs:

  • Lack of licensing or insurance: Always ask for proof.
  • High-pressure sales tactics: Reputable companies will give you time to make decisions.
  • Vague quotes: Ensure everything is itemized, including labor, materials, and cleanup.
  • No warranty offered: A reliable waterproofing solution should come with a warranty.
  • Poor reviews or no references: Look for a history of satisfied customers.

Taking the time to vet your contractor minimizes risks and ensures you get quality service.

Our basement started flooding after heavy rains, and we were panicking about long-term damage. Waterproofing Pros sent an expert out the next day who found the issue and installed a sump pump that afternoon. The peace of mind was priceless, and it cost less than we'd feared!
