Basement Waterproofing Cos

The Cost of Basement Waterproofing

Basement waterproofing costs can range from $2,300 to $7,575, with an average cost of $4,920. However, the cost of basement waterproofing depends heavily on the waterproofing methods. Generally, there are two ways to waterproof the basement: interior and exterior waterproofing. 

1. Interior Basement Waterproofing 

As the name suggests, interior basement waterproofing focuses mainly on waterproofing the inside of your home.  It generally includes waterproofing methods such as applying sealants or coatings to the interior walls and floors, installing drainage systems like drain tiles or French drains, and using sump pumps to remove collected water.

Moreover, the cost of waterproofing the basement from the inside ranges between $200 and $3,000. 

2. Exterior Basement Waterproofing

The exterior basement waterproofing method focuses on preventing water from entering the basement through the outdoor walls of the foundation. It involves applying barriers or coatings to the exterior walls of the basement. 

In addition, exterior basement waterproofing can involve excavation around your home to access the foundation walls, installing exterior waterproofing membranes, drainage systems, or coatings. Because of this, exterior basement waterproofing can cost from $1,000 to $15,000

Interior Basement Waterproofing And The Related Costs 

1. Interior Sealants or Membranes

One of the most cost-effective ways to waterproof the basement is interior sealing. Though it doesn’t involve coating the entire basement, it can effectively target minor issues in the foundation. These waterproofing sealants are applied to the interior walls and floors of the basement to create a waterproof barrier. 

The cost of interior sealants ranges from $3 to $7 per square foot, depending on the type of sealant chosen. While interior sealants can temporarily solve water infiltration problems, they may not be sufficient for more severe water damage.

2. Sump Pump Installation

Sump pumps are essential components of interior basement waterproofing systems. They are responsible for pumping out excess water and are installed in a pit to collect the water from the drainage system. The cost of installing a sump pump generally ranges from $600 to $1,900, including both the pump and the installation. Additional features, such as battery backup systems or alarms, may increase the overall cost.

3. Interior Drainage Systems

Interior drainage systems, such as drain tiles or French drains, are designed to collect and redirect water away from the basement. Interior drainage systems are connected to a sump pump, which takes the collected water out of the basement. The cost of installing an interior drainage system varies depending on factors such as the size of the basement and the extent of drainage needed. On average, homeowners can expect to pay between $10 and $100 per square foot for an interior drainage system.

4. Basement Wall Panels

Basement wall panels are another interior basement waterproofing option. These are made from materials such as plastic or fiberglass and are installed directly onto the interior walls of the basement. The cost of installing basement wall panels varies depending on the material chosen and the size of the basement. On average, you can expect to pay between $25 and $100 per basement wall panel, adding up to the total basement waterproofing cost. 

Exterior Basement Waterproofing And The Associated Costs

1. Exterior Waterproofing Membranes

Exterior waterproofing membranes are a practical solution for preventing water infiltration in basements. These membranes are applied directly to the exterior walls and are typically made from materials like asphalt-modified polyurethane or rubberized asphalt. 

The cost of installing exterior waterproofing membranes ranges from $1,000 to $15,000, which is a small price to pay for the peace of mind that comes with knowing your basement is protected against water damage.

2. Excavation Waterproofing

Excavation waterproofing involves digging out the soil surrounding a house’s foundation to apply a waterproof membrane or coating on the exterior walls. This waterproofing method is ideal for homes with significant water damage problems. This technique provides full protection against water intrusion. The cost of excavation waterproofing can range from $120 to $220 per linear foot. 

3. Exterior Drainage Systems

Exterior drainage systems, like French drains or footing drains, are installed around the home to gather and redirect water away from the foundation. These systems reduce the risk of water infiltration by preventing water from pooling around the basement walls. The cost of an exterior drainage system installation varies depending on factors such as the home’s size and the extent of drainage needed. The average cost for homeowners to install an exterior drainage system is between $10 and $50 per linear foot.

4. Exterior Waterproofing Coatings

Exterior waterproofing coatings can be applied directly to the outer walls of a basement to create a protective barrier against water penetration. These coatings are typically made from cementitious or polymer-based materials and can be sprayed or brushed onto the surface of the walls. On average, homeowners can expect to pay around $2 to $5 per square foot for cementitious exterior waterproofing, and $3 to $7 per square foot for polymer-based coatings.

Final Thoughts 

Apart from the techniques used, basement waterproofing costs will depend on the size of your foundation, the labor involved, the materials incorporated, and your location. So, when deciding to waterproof your basement, consider all these factors before making this significant financial investment.
