Do you offer crawl space clean out services?
While we do not offer crawl space clean out as a standalone service, we ensure your crawl space is properly prepared for any project we undertake. Before beginning an installation for services like waterproofing or foundation repair, our team will remove any debris that could interfere with the work. For projects requiring more extensive clearing or dig outs, we coordinate with trusted subcontractors to handle the process.
Our primary focus is to provide a comprehensive and lasting solution for your foundation and waterproofing needs, which begins with a properly prepared space.

What Are the Top Signs Your Crawl Space Needs Attention?
You don’t have to be an expert to spot the warning signs of a crawl space problem. Keep an eye out for these indicators:
Musty or earthy smells, especially on the first floor
A feeling of dampness or high humidity indoors
Worsening allergy symptoms that seem to improve when you leave the house
Buckling or cupping hardwood floors on the main level
Visible mold or mildew on baseboards or in closets
Increased pest activity, such as insects or rodents
Cold floors during the winter months
Unusually high heating or cooling bills
Do you do commercial building waterproofing?
Yes, we provide comprehensive interior waterproofing services for commercial buildings. Our team identifies and addresses potential water intrusion points to ensure your property remains dry and protected. Our experts will tailor a solution to meet the specific needs of the building, using the latest techniques and high-quality materials.
Do you repair sagging floor joists?
Yes, we repair sagging floor joists using a high-quality system designed for durability and effectiveness. Our process involves replacing the sagging beam with a steel supplemental beam and installing SmartJacks to provide strong support. The SmartJacks are specifically engineered to reduce floor bounce and lift the floors back toward their original position, ensuring your structure is stable and secure.
How much does crawl space encapsulation cost?
The cost of crawl space encapsulation can vary because every home is different. Key factors influencing the price include the total square footage of your crawl space, its current condition, and the specific encapsulation products required to permanently protect your home. For example, a larger crawl space or one with existing moisture damage and debris will require a different approach than a smaller, cleaner space.
Because the final cost depends on these unique factors, we provide a free, no-obligation inspection for homeowners. One of our specialists will evaluate your crawl space to identify any issues and determine the most effective solutions. Afterward, we will provide a detailed estimate tailored specifically to your home’s needs, so you know exactly what to expect for your crawl space encapsulation project.
How often should I service my waterproofing system?
We suggest servicing your basement waterproofing system at least once a year to identify signs of wear and tear, such as moisture buildup or cracks. Early detection allows you to address these issues before they become more severe and compromise your basement’s protection.
We recommend an annual service to ensure your sump pump system functions correctly. We suggest servicing the sump pump every six months to ensure its longevity. Additionally, monthly cleanings and quarterly assessments can help keep your sump pump in optimal working condition.
What are helical piers?
Helical piers provide permanent stabilization for a home’s foundation and, in most cases, can lift it back to its original position. Made of steel, these piers are screwed into the soil adjacent to the foundation. They are then connected to the home’s foundation using steel brackets, effectively transferring the weight of the house from unstable ground to the secure piers. Helical piers come with a 25-year warranty, ensuring long-term reliability and peace of mind.
What does it mean if I have horizontal foundation cracks?
Horizontal cracks on your foundation walls indicate that the walls are starting to bow inward due to excessive pressure from the soil outside. This pressure can result from overly compressed backfilled soil or hydrostatic pressure from heavy rain followed by a freeze. Bowing walls are a serious issue as they can lead to structural failure and, ultimately, home collapse.
What is the average cost of a crawlspace encapsulation?
The cost of crawlspace encapsulation can vary significantly based on several factors, primarily the size and condition of the crawlspace. For smaller crawlspaces, you can expect to pay between $4,000 and $8,000. Larger homes with more extensive crawlspaces may see costs upwards of $10,000 or more. If the crawlspace is in poor condition, additional remediation work may be necessary before encapsulation can begin, which can add to the overall expense.
Why do I need a dehumidifier for my crawlspace?
A dehumidifier for your crawl space efficiently controls moisture levels, preventing mold and mildew growth. The SaniDry dehumidifier improves indoor air quality by reducing allergens and protects metal objects from rust and corrosion. It operates quietly and efficiently, with a durable design that ensures long-term use. The SaniDry is easy to operate and maintain, making it an excellent investment for a healthier and more comfortable home environment.
Why would a house need a sump pump?
A house may need a sump pump to effectively manage water intrusion in the basement and prevent potential flooding. Sump pumps actively pull water out of the basement and direct it away from the property, helping prevent flooding and protect the foundation’s structural integrity.





Homeowners often forget about their crawl spaces. However, issues with your crawl space can impact your entire home. A wet or otherwise damaged crawl space can lead to poor indoor air quality, uneven interior floors, and other costly problems.
