Basement Waterproofing & Foundation Repair

At Costello Construction, we specialize in basement waterproofing and foundation repair, two essential services that protect your property from water damage, structural issues, and the threats that can arise from an unstable foundation. Whether you're dealing with dampness in your basement or notice cracks in your foundation, we are here to help you safeguard your home for years to come.

Why Basement Waterproofing & Foundation Repair Matter

A solid foundation and dry basement are the bedrock of a healthy home. Neglecting issues in these areas can lead to severe damage that affects the value, comfort, and safety of your property.

common problems our services address:

  • Water Damage in the Basement: Excess moisture in your basement can lead to mold growth, wood rot, and structural deterioration. Waterproofing prevents water intrusion, ensuring your basement remains dry and livable.

  • Cracks in Foundation: Over time, foundations can shift, settle, or crack due to a variety of factors like soil movement, poor construction, or age. Cracked foundations can cause doors and windows to become misaligned, lead to uneven floors, and compromise your home’s overall stability.

  • Leaks and Flooding: Basement leaks can occur during heavy rain or melting snow, especially if your home is in an area prone to flooding. Waterproofing is the first line of defense to prevent leaks and the costly damage that comes with them.

  • Structural Integrity: A compromised foundation can jeopardize the structural integrity of your entire home. Foundation repair ensures your home stays safe and stable.

Our Approach to Basement Waterproofing & Foundation Repair

At Costello Construction, we combine the latest technology and techniques with our years of expertise to provide effective, long-lasting solutions for your foundation and waterproofing needs.

  • We begin by thoroughly inspecting your basement and foundation. Our team looks for signs of water intrusion, cracks, shifting, or settling. Using this information, we create a customized plan that addresses the specific needs of your home.

    • Interior Waterproofing: This includes installing a sump pump system, drainage channels, and waterproof sealants to direct water away from the foundation and prevent it from entering your basement.

    • Exterior Waterproofing: For a more comprehensive solution, we can apply a waterproof membrane to the exterior of your foundation. This involves digging around the perimeter of your home to access the foundation and applying a protective layer that prevents water from penetrating.

    • Crack Injection: For minor cracks, we use specialized epoxy or polyurethane injections to fill the cracks and restore the integrity of your foundation.

    • Foundation Piering: For more severe foundation issues, we use piering techniques that stabilize your foundation by driving steel piers deep into the ground until they reach stable soil. This method can lift and level your foundation to correct settling or shifting.

    • Wall Stabilization: If your basement walls are bowing or leaning, we offer wall stabilization systems like carbon fiber straps or steel braces that prevent further movement and restore the structural integrity of your foundation.

  • After completing the repairs or waterproofing installation, we conduct a final inspection to ensure everything is properly sealed and stable. We will walk you through the work performed and answer any questions you have about maintaining your newly waterproofed basement or repaired foundation.
